- Water escaping where a screen meets the wall
- Stained, discoloured glazing silicone
- Sealant that was laid over old silicone and failed
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Keep conservatory gutters clear of leaves
- Do not use a blade near the sealant
- Use a gentle glass cleaner and a soft cloth
- Check the silicone on glass every year or so
Look over the glazing joints every year or so. Catching a split early keeps the repair small, before water gets in.
A small conservatory leak soon spreads. Water runs along frames and down walls so it’s best dealt with right away.
Glazing silicone for homes and businesses in Coolham
Many conservatory leaks come down to failed sealant, where glass meets frame or frame meets wall. We find the joint that’s letting water in and renew it and tell you plainly if the cause is something else. If you’re dealing with conservatory leaks at frame and glazing joints and water tracking down the inner face of the glass, we can put it right, on glass-to-glass joints, glass balustrade bases and rooflights alike.
Around Coolham, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

Coolham questions
Can you help a landlord with a rental near Billingshurst station?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can go on one quote. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Do you cover Coolham for glazing silicone?
Yes. We work across London and the South East, and Coolham is part of that. You can ring 0345 464 0079 or send us an email and let us know what needs doing.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Can I add another job to the visit?
Yes, we can. More than one area can go on one quote.
Can you reseal the base of a glass balustrade?
Yes, where the base is finished with sealant. Send us pictures and we will take a look when you call 0345 464 0079 or drop us an email.
Do you replace glass?
We do not replace glass. We reseal the joints around it and can tell you if a unit seems to have gone.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint.
Do the sealants smell?
Sometimes, a little. Any smell clears as the sealant cures.
How the visit works
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and clear up. It usually takes a few hours, depending on how many joints need doing. In a small place like Coolham, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
Getting ready for the visit
- On commercial sites, let us know about site rules
- Mention if the joints have been sealed before
- Let us know about parking restrictions
How to get a quote
We quote each job on its own, so the first step is telling us about yours. Simply phone 0345 464 0079 or drop us an email and describe the job.
Advice
Leave it or put it right?
A quick bead over the old sealant might stop a drip for a while, but new silicone won’t bond to old and water soon finds its way back. Cutting out and resealing properly lasts. Where a wall is exposed, as many are in small places like Coolham, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part.

Frames and glazing around Coolham
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Rented homes near Billingshurst station change hands often, and glazing joints are worth checking at the end of a tenancy, before a small leak grows. If you look after a building such as William Penn School, the mastic around its windows and doors needs looking after like any other building’s. For an older house near a landmark such as St Mary's Mission Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What we seal
- Conservatory frames
- Glass-to-frame joints
- Rooflights
- Glass balustrade bases
- Shower screens
- Glass-to-glass joints
What the job involves on each surface
Glass balustrade bases
We reseal the joint where the glass meets the base channel. Glass fitting is a separate trade.
Conservatory frames
Conservatory frame joints are a common source of leaks. We cut out the old sealant and reseal.
Can I do it myself?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
A DIY attempt does not rule out a professional job. We cut it out and start again.
