What Does Resealing a Window Actually Mean?
Are you looking for how to reseal windows? Resealing a window means applying fresh sealant around the window frame to close any gaps or cracks that may have formed over time.
It’s a practical way to restore energy efficiency, prevent water ingress, and block draughts — all without replacing the entire window unit.
Is Resealing Just About Applying New Silicone?
Not quite. While silicone sealant is a key part of the process, resealing also involves:
- Removing old, deteriorated sealant
- Cleaning and prepping the area
- Applying a smooth, even seal
- Allowing time for curing

Which Parts of a Window Typically Need Resealing?
You’ll usually reseal:
- Around the external perimeter of the window frame
- Where the frame meets the wall or brickwork
- Sometimes internally, if there’s draught or water ingress
Why Should You Reseal Windows?
Are You Losing Heat or Energy Through the Window Seals?
Yes — damaged seals allow cold air to creep in and warm air to escape, forcing you to crank up the heating. This leads to:
- Higher energy bills
- Less consistent room temperatures
- Reduced comfort during winter
How Can Broken Seals Cause Condensation Between Panes?
If you see mist or condensation between double-glazed panes, it usually means the sealed unit has failed. Moisture gets trapped inside, which:
- Reduces thermal performance
- Affects visibility
- Can even cause mould growth
Note: Resealing won’t fix condensation inside glazing — for that, you’ll need the unit replaced.
Can Resealing Reduce Draughts and Noise?
Absolutely. A fresh seal:
Is It Cheaper Than Replacing Windows?
Definitely. Resealing costs a fraction of full replacement. If your window frames and glazing are still in good condition, resealing is a smart, budget-friendly alternative.
When Should You Reseal Your Windows?
What Are the Signs Your Window Seals Have Failed?
Keep an eye out for:
- Cold draughts even when windows are closed
- Black mould or damp patches around the frame
- Cracked, brittle, or missing sealant
- Increased condensation or foggy double glazing
- Peeling paint or soft woodwork
How Often Should You Reseal Double Glazed Units?
Window sealant can last 5 to 15 years, depending on exposure. South-facing windows or those facing heavy rain may degrade faster.
It’s good practice to inspect seals annually and reseal when needed.
Is Seasonal Maintenance a Good Idea?
Yes — autumn is ideal for resealing, just before the cold and wet winter months hit. Sealing then ensures better insulation and weather protection.

How to Reseal Windows? – Step-by-Step DIY Guide
Here’s your toolkit for resealing:
- Silicone sealant (exterior-grade for outside use)
- Caulking gun
- Utility knife or scraper
- Sealant remover or rubbing alcohol
- Cleaning cloths
- Masking tape (optional for cleaner edges)
- Gloves
How to Safely Remove Old Sealant?
- Utilize a utility knife / scraper to cut along the corner of the old sealant.
- Gently peel away the material.
- Scrape any leftover residue.
Be patient — the cleaner the surface, the better the new seal will bond.
Cleaning and Preparing the Surface
- Wipe the area with rubbing alcohol or sealant remover.
- Let it dry completely before applying new sealant.
- Use masking tape around the edge (optional) to help keep your lines neat.
Applying New Silicone Sealant Evenly
- Load the sealant tube into your caulking gun.
- Chop the nozzle at a 45° angle.
- Apply steady pressure to get down a smooth, even bead.
- Move a wet finger or finishing tool along the seal to smooth it.
Tip: Don’t rush. Take it section by section for a clean finish.
How Long Does Sealant Take to Cure?
Most silicone sealants take:
- 24 hours to cure for light use
- Up to 72 hours for full waterproofing and bonding
Avoid touching or cleaning the area during this time.
Should You Reseal from the Inside or Outside?
What’s the Difference Between Interior and Exterior Sealing?
- Exterior resealing blocks rainwater and wind from entering
- Interior sealing helps with air draughts and aesthetics
When Is It Best to Reseal Externally?
If you’re feeling draughts, seeing damp patches, or have visibly cracked exterior sealant, then external resealing should be your priority.

Clover can be a bit of a nuisance in any garden, especially when you’ve spent time and effort trying to maintain a lush, green lawn.
I used to think it added some charm – until it started taking over my entire yard. If you’re in the UK and wondering how to get rid of clover in lawn uk, I’ve got you covered.
Here’s what I learned through my own experience, and the top 3 methods that worked best for me.
Why Is Clover Growing in My Lawn?
What Causes Clover to Spread in UK Lawns?
Before I could tackle the issue, I had to understand why clover was thriving in the first place. In most UK lawns, clover (especially white clover) tends to appear when:
In short, clover loves stressed lawns. It actually fixes nitrogen in the soil, which helps it thrive even when grass struggles.
Is Clover Really a Weed or Can It Be Useful?
I’ve read arguments in favour of keeping clover – it’s low maintenance, attracts bees, and stays green during drought.
But honestly, when it starts crowding out your grass, it becomes a weed in my book. My goal was to maintain a uniform, healthy lawn, and that meant clover had to go.
How Can I Identify Clover in My Garden?
Types of Clover Found in UK Lawns
The most common one I dealt with was white clover (Trifolium repens). It’s easy to spot with its small white flowers and three rounded leaves.
Sometimes, red clover can appear too, which grows taller and has pinkish-purple flowers.
Signs Your Lawn Has a Clover Infestation
- You’ll see patches of small white flowers
- Leaves grow in clusters of three or even four, if you’re lucky!
- Grass looks thin and is overtaken by creeping stems

What Are the Top 3 Ways to Remove Clover from My Lawn?
Here are the three methods I used – all of which worked in different ways depending on how bad the infestation was.
1. Manual Removal Techniques
How I Pulled Out Clover Without Chemicals?
When the clover patches were small, I just rolled up my sleeves and pulled them out by hand. I made sure to take out the roots to keep away from regrowth.
- Garden fork or hand weeder
- Gloves
- Watering can (moist soil makes pulling easier)
Tip: Try doing this after rain or watering the area to soften the ground.
2. Natural Remedies That Actually Work
Vinegar, Boiling Water & DIY Sprays
This method was eco-friendly and easy. I mixed vinegar with a few drops of washing-up liquid and sprayed directly onto the clover. Within days, the leaves began to shrivel.
Boiling water is another quick fix, but be careful – it’ll kill any grass it touches too.
Adjusting Soil Conditions
Clover thrives in nitrogen-poor soil, so I used a high-nitrogen lawn fertiliser to give the grass a boost and make the lawn less friendly to clover.
3. Chemical Lawn Treatments in the UK
Best Clover Weed Killers Available
When things got out of control, I turned to selective weed killers. These are designed to kill broadleaf weeds like clover without harming your grass.
Some options available in UK garden centres:
- EverGreen Complete 4 in 1
- Resolva Lawn Weedkiller
- Weedol Lawn Weedkiller
Safety Tips and Application Guide
- Always follow the label
- Apply in dry weather with no rain forecast for 24 hours
- Make sure that pets & kids are away from the lawn until dry
Can I Prevent Clover from Coming Back?
How I Strengthen My Lawn to Resist Clover?
After removing the clover, I focused on long-term lawn care:
- Regular mowing (but not too short)
- Feeding the lawn every 6–8 weeks
- Aerating the soil in spring and autumn

Overseeding, Fertilising, and Watering Tips
I started overseeding bare patches with grass seed to crowd out new weeds. Then I applied slow-release fertiliser to encourage thick, healthy grass.
Consistency really is key – the more you maintain your lawn, the less chance clover has to come back.

Final Thoughts: How I Got My Lawn Back from Clover
Getting rid of clover in my lawn took a bit of trial and error, but once I understood why it was growing, everything started to make sense.
The combination of manual effort, natural tricks, and chemical support finally gave me back the lush green lawn I wanted.
If you’re struggling with the same issue here in the UK, just remember – you’ve got options. Pick the method that suits your lawn and your lifestyle, and be consistent. You’ll be clover-free in no time.
Frequently Asked Questions On How to Get Rid of Clover in Lawn UK
1. Can I use vinegar to kill clover?
Yes! I’ve had reasonable outcomes with vinegar mixed with dish soap. Just apply carefully – it can damage surrounding grass.
2. Will fertiliser alone stop clover growth?
Not immediately, but over time, a well-fed lawn becomes thick and healthy enough to crowd out clover.
3. How long does it take to see results?
Manual removal is instant. Natural and chemical methods can take a few days to two weeks depending on severity.
4. Is clover harmful to pets?
Not usually – clover itself is safe. But if you’re using weed killers, keep pets off the lawn until it’s dry and absorbed.

Understanding Condensation on Windows
Condensation is what I’ve had to meet with in nearly every UK home I’ve lived in. It appears as small water droplets on glass, often in the mornings or during cold weather.
Scientifically, it happens when warm, moist air inside meets a colder window surface, causing water vapour to turn into liquid.
In the UK’s damp, cool climate, condensation on windows is extremely common, especially in winter. While a little moisture might seem harmless, over time it can lead to black mould, wood rot, and damage to window seals.
Learning how to stop condensation on windows isn’t just about aesthetics — it’s about protecting your health and home.
1. Indoor humidity
A usual day activities such as cooking, showering, and drying clothes indoors release water vapour. Without enough ventilation, this moisture lingers and at the same time it condenses on surfaces that are colder.
2. Poor ventilation
Modern homes are often sealed tightly to improve energy efficiency. Unfortunately, this traps moisture inside.
3. Temperature differences
When indoor air is warm but your windows are cold (especially single glazing or poorly insulated double glazing), condensation is more likely to form.
4. Damaged window seals
If your double glazing has failed, moisture can form between the panes, leading to misty glass that can’t be wiped away.

What are the Different Types of Condensation on Windows?
Condensation inside windows
Appears on the room-facing surface of the glass. This is caused by high indoor humidity and low ventilation.
Condensation on the outside of windows
Occurs when the outer pane is cooler than the morning air. Usually harmless and tells you that your double glazing is insulating fine.
Condensation between double glazed windows
This is a sign of a blown window — the seal has failed, letting moisture inside the sealed unit.
When I’ve woken up to water-covered bedroom windows, I’ve relied on a few simple tricks:
- Hairdryer method – For emergency use on small areas and to remove moisture from between window panes, it can help dry moisture, but it’s temporary.
- Window vacuum – Quickly removes pooled water before it causes mould or frame damage.
- Daily wipe-down – A microfibre cloth absorbs water without smearing.
These methods give instant results, but they don’t solve the underlying humidity problem.

How to Prevent Condensation on Windows?
To keep condensation from returning, I’ve learned to focus on reducing humidity and improving airflow:
- Install trickle vents – These small vents on window frames allow fresh air to circulate without big heat loss.
- Improve extractor fan performance – Upgrade bathroom and kitchen fans to more powerful, humidity-sensitive models.
- Maintain steady indoor temperatures – Avoid sudden drops in heating which make windows cold enough for moisture to settle.
How to Stop Condensation on Double Glazed Windows in Winter?
Even good double glazing can mist up in winter because the inner pane still cools enough to trigger condensation when humidity is high.
Keeping the heating steady, ventilating rooms briefly each day, and using a dehumidifier can help. Make sure curtains or blinds aren’t blocking airflow around the window, as this can trap moist air against the glass.
How to Get Rid of Condensation in Between Double Glazed Windows?
If you have misting inside the window space, the original airtight seal has failed and lost its job. No amount of surface cleaning will work here.
You have two main options:
- Dry out a blown window using micro-drilled holes along with the silica gel (temporary)
- Replace the sealed unit (permanent)
How to Dry Out a Blown Window?
I’ve tried this on an old kitchen window to buy time before replacement:
- Drill a small hole in the spacer bar or edge of the glass unit.
- Use a dehumidifier positioned right next to the hole to draw moisture out.
- Insert silica gel beads to absorb any remaining water.
- Seal the hole with weatherproof sealant.
It worked for around 18 months before misting returned.

How to Fix Condensation in Double Glazing?
Can condensation in double glazing be fixed?
Yes — but usually only temporarily. Once the seal has failed, it can’t be restored to factory condition.
DIY methods On How to Fix Condensation in Double Glazing?
Micro-drilling and drying, replacing seals, or adding moisture-absorbing materials.
When to reseal windows – How to Reseal Windows?
If the gap is small and accessible, resealing can slow moisture ingress.
When replacement is the only option?
If misting returns quickly after a fix, replacing the glass unit is the only long-term answer.
Natural Remedies – Does Vinegar Stop Condensation on Windows?
How vinegar helps reduce surface condensation?
Vinegar modifies the surface tension of glass, making it harder for water droplets to cling.
Limitations – it won’t fix blown seals
This method only helps with surface condensation and has no effect on trapped moisture inside double glazing.

How to Stop Condensation on Windows Overnight? – Seasonal Condensation Control
Why cold weather increases condensation risk?
Low outdoor temperatures make the inner glass pane cold, so moisture condenses more readily.
Bedroom-specific solutions:
Keep trickle vents open, use a small gap in the window, and avoid drying laundry in the bedroom.
Night ventilation tips without losing heat
Use latest window night locks or short morning airing sessions.
Special Cases – Skylight and Roof Windows
Why skylight windows get condensation easily? – Clean Skylight Windows From Inside
Warm, moist air rises to the roof space, where it meets cold skylight glass. Regular cleaning keeps surfaces free of dust and grime that hold moisture.
Tips for prevention in hard-to-reach glass
Ensure loft ventilation is adequate and surrounding insulation is intact to keep the glass warmer.

Final Thoughts – Clear Windows All Year Round
Dealing with condensation on windows means first identifying its type and cause.
Quick fixes like wiping down or using a hairdryer are fine for emergencies, but long-term prevention requires ventilation, humidity control, and sometimes professional repair.
From how to stop condensation on windows overnight to how to dry out a blown window, the methods here will help you protect your windows and your home from the damaging effects of moisture.
FAQ – Common Questions About How to Stop Condensation on Windows
1. How long does it take to get rid of condensation?
Surface moisture can be wiped away instantly, but full prevention takes ongoing effort.
2. Is vinegar safe for all window types?
Yes, it is safe to use vinegar for glass, but keep it away from wooden frames.
3. Will new double glazing stop condensation completely?
It reduces it greatly, but surface condensation can still occur with high indoor humidity.
4. Should I use a hairdryer every day?
No — it’s fine in emergencies but prolonged use can damage seals.

The Day I Discovered My Blown Window
I first noticed it on a chilly November morning. The sun was shining through my living room window, but instead of a clear view, I saw cloudy streaks trapped inside the glass. This wasn’t normal surface condensation — this was inside the double glazing.
If you’ve ever seen this, you probably have a blown window. Then there comes the question how to dry out a blown window.
It means the airtight seal around your double-glazed unit has failed, letting moisture in. In the UK, where damp conditions are common, blown windows aren’t rare.
Instead of rushing to replace the whole unit, I wanted to see if I could dry out the blown window and remove the moisture between the panels. Here’s exactly how to dry out a blown window — and what I learned along the way.
What Is a Blown Window?
Meaning of “blown” in double glazing terms
A “blown window” simply means the sealed unit in your double glazing has failed. The airtight seal around the two panes of glass has broken, allowing air — and with it, moisture — to get in.
Why moisture gets between the glass panels?
Moisture enters through tiny gaps in the perimeter seal. Once inside, it condenses because the space between the panes is cooler than the surrounding air. Over time, the condensation builds up and causes a foggy appearance.
Signs your double glazing seal has failed
- Mist or fog trapped between the glass layers
- Water droplets inside the pane
- Distorted reflections
- Draughts or noticeable temperature changes near the window

Can You Really Dry Out a Blown Window?
When it’s possible to remove condensation without replacing the unit?
If the glass itself is intact and the frame is in good condition, you can sometimes dry out the window by allowing the trapped moisture to escape and then resealing it.
When replacement is the only realistic option?
If the glass is cracked, the frame is rotting, or the seal damage is extensive, drying it out is a temporary fix at best.
Risks of a DIY drying job
- Drilling incorrectly can crack the glass.
- Moisture may return if resealing isn’t perfect.
- May void any remaining warranty on the unit.
- Electric drill with a fine glass drill bit (3mm–4mm)
- Safety glasses and gloves
- Low-tack masking tape (to protect the surface)
- Silica gel beads or a moisture absorber
- Small funnel or syringe (for inserting silica gel)
- Clear weatherproof sealant
Optional items
- Dehumidifier for faster drying
- Anti-fog glass treatment for temporary clarity
Step-by-Step Guide – How To Dry Out a Blown Window?
Step 1 – Inspecting the seal and glass
Before touching any tools, I carefully examined the glass edges to find the point where the seal had failed. I also checked the frame to ensure it was solid.
Step 2 – Drilling micro-holes in the spacer bar or frame
I used masking tape on the drill point to prevent slipping. Then, using a fine drill bit, I made a small ventilation hole in the spacer bar or corner of the frame — never in the middle of the glass pane.
Step 3 – Removing moisture from between the glass panels
With the hole in place, I positioned a dehumidifier right next to the window for 24–48 hours. This gradually drew moisture out through the hole.
Step 4 – Using silica gel or moisture-absorbing materials
I inserted silica gel beads into the spacer cavity using a small funnel. These beads absorb any remaining moisture and help keep the space dry.
Step 5 – Resealing the glass to prevent further condensation
Once completely dry, I sealed the hole with clear weatherproof sealant to restore the airtight barrier.

Alternative Methods I’ve Tried for Removing Moisture
Dehumidifier against the glass
Placing a dehumidifier directly in front of the blown window can reduce moisture over several days, but it’s slower without ventilation holes.
Warm air drying
A hairdryer on low heat can temporarily clear condensation for a day or two, but it doesn’t remove the moisture permanently.
Specialist window repair kits
In the UK, some kits come with micro-drill bits, silica gel, and vent plugs designed for DIY defogging.

How to Prevent Blown Windows in the Future?
Maintenance tips to keep seals intact
- Avoid pressure washing windows directly at the seals.
- Keep drain holes in the frame clear so water doesn’t pool.
- Inspect seals annually for early signs of wear.
Reducing humidity inside your home
- Use extractor fans when cooking or showering.
- Ventilate regularly, especially in winter.
- Keep indoor humidity around 40–50%.
Choosing quality double glazing
Invest in windows with warm-edge spacer bars and high-quality seals for longer lifespan.
Final Thoughts
Knowing how to dry out a blown windowing and doing it can give you back a clear view without the cost of full replacement, but it’s usually a temporary fix. In my case, it bought me another year before I replaced the unit.
If you’re confident with tools, the drill-and-dry method with silica gel works well. Just remember — sealing the unit properly is the difference between a fix that lasts months and one that lasts years.
FAQ – How to Dry Out a Blown Window?
1. How long does it take to dry out a blown window?
With the drill-and-dry method, expect 1–3 days depending on moisture levels.
2. Will the moisture come back?
If you don’t fix the seal properly, yes. Even a perfect DIY job may only last 1–2 years before misting returns.
3. Is drilling the glass safe?
Yes, if you use the correct drill bit, go slowly, and drill only in the spacer bar or frame area.
4. Can I use a hairdryer or heat gun?
Only as a short-term fix — it won’t solve the root problem.
