The process
On the day, we look over the joints with you first, so you know exactly what we’re doing. Surfaces next to the work are protected before work begins. The work generally takes anything from an hour or two to most of a day, depending on the size of the job. Parking around Apsley is normally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- First, we check where the water gets in.
- The failed silicone is cut out without marking the glass or frame.
- The joint is cleaned and degreased.
- We lay the new bead and tool it smooth.
- We check the finished joints and test with water where it’s safe.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Keep pets and children clear of the area while we work
- Move anything stored near the joints
How to get a quote
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that’s easy.

Glazing silicone for homes and businesses in Apsley
Glazing silicone that has yellowed, blackened or come away looks poor and can leak. It comes off cleanly, without marking the glass before the new bead goes in. We work on rooflights, glass balustrade bases and conservatory frames, and common reasons people get in touch are silicone pulling away from the glass and new silicone smeared over old sealant.
Around Apsley, conservatories, garden rooms and patio doors are often part of the house. Those joints need the same attention as the main windows.
A one-year guarantee comes as standard, so you are covered after we have gone.

What glazing silicone looks like in Apsley
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as High Elms Manor (about 4.1 miles south-east) nearby, there’s older building stock in the area around Apsley as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
If you let a flat or house near Apsley station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. Historic houses such as High Elms Manor, about 4.1 miles south-east, show how far back building around Apsley goes. For site and facilities teams at buildings such as Two Waters Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

How we quote for glazing silicone
We do not publish a price list, because no two jobs are the same. What we look at:
- Working hours on commercial sites
- The type of sealant required
- How easy the joints are to reach
- How much old sealant there is and how hard it is to remove
The cost reflects the work involved, not guesswork. That is why we ask a few questions first and give you a clear price before work begins.
Asking for a quote
To make quoting easier, please include:
- Any previous sealing or DIY work
- What’s wrong with the joints now
- Where the job is, and your postcode
- The rough size of the job
Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we will talk you through the work and give you a clear price.
How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Don’t leave a drip for the next storm
- Clear the conservatory gutters regularly
- Look over the glazing joints once a year
- Wipe the screen down after showering
Check the joints once a year. Catching a split early keeps the repair small.
Shower screen leaks can go unnoticed. It can damage the floor or the ceiling below long before you see it.
Apsley: your questions answered
Will you come out to Apsley?
Yes. Apsley is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is it worth replacing old sealant in an older home in Apsley?
Generally, yes, if it’s cracked, shrunk, mouldy or coming away. New sealant won’t stick to old, so the old bead has to come out completely first.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
I rent my home. Can I book you?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.
Can you reseal the base of a glass balustrade?
Yes, we reseal the joint at the base channel. We do not install or replace the glass.
What sealant do you use on glazing?
A neutral-cure glazing silicone that suits the glass and frame. In bathrooms, we use anti-fungal silicone.
Can you reseal a frameless shower screen?
Yes. We remove the old sealant and reseal the wall and tray joints.
Surface by surface
Rooflights
We reseal the glazing joints on rooflights. If the leak is from the roof around it, a roofer needs to look.
Glass-to-glass joints
You see these joints clearly, so a straight, even finish matters.

Can I do it myself?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Leave it or put it right?
Replacing a conservatory roof is major work. Where the water is getting in through sealant renewing the joint is the simpler fix. If the roof is the problem, we will say so. In a smaller place like Apsley, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
