Glazing silicone in High Garrett, done properly
Glass, frames and walls all move at different rates, so the sealant between them does a lot of work. When it cracks or lets go, water gets in. We replace it with a glazing silicone that suits the glass and frame. Typical jobs include rooflight joints letting water in and glass-to-glass joints that have split, on glass-to-glass joints, conservatory frames and rooflights.
Outdoor sealant needs dry, clean surfaces, so work on frames around High Garrett is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

DIY versus a professional finish
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.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.

Windows and doors in High Garrett
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Schools such as Bocking Church Street Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

What happens if it’s left?
Replacing a conservatory roof is major work. Where the water is getting in through sealant, resealing is far simpler. If it’s the roof itself, we will tell you. In a small place like High Garrett, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, ring 0345 464 0079 or send us an email for an honest opinion and a quote.

Questions from High Garrett

How much does glazing silicone cost in High Garrett?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before we start.
Is it worth trying it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Where is Mr Mastic based?
We’re based in Crawley, West Sussex, and we work across South East England, London and Scotland.
Can you work on commercial sites?
Yes. We have worked for hotels, offices and other businesses, and we are fully insured.

Are you ARBOMaster approved?
Yes. We’re approved under the ARBOMaster scheme.
Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Ventilate the conservatory to cut condensation
- Get a new leak looked at quickly
- Don’t use a blade near the sealant
- Use gentle products around the joints
Look over the glazing joints every year or so. Spotting a crack early means a simpler fix.
Damp patches, drips and condensation along a joint are worth checking. The cause may be sealant or another part, and we will tell you which.

Surface by surface
Rooflights
Rooflights get the full force of the weather. The sealant around the glass and frame wears faster than most.
Glass-to-glass joints
Frameless glass corners and panels are joined with silicone. We reseal with a suitable glazing silicone.
What happens on the day
On the day, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before work begins. Most jobs take a few hours for most jobs.
