How we handle glazing silicone in Cranmore
Glazing silicone is a maintenance item. Sun, rain and movement wear it down and cracked joints let water in. Renewing it keeps glazing joints doing their job. We’re often asked to deal with black or yellowed silicone on glass joints and rooflight joints letting water in, across glass balustrade bases, glass-to-frame joints and rooflights.
Around Cranmore, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
Each job carries a 12-month guarantee.

What else we do in Cranmore
Different surfaces, different methods
Glass-to-glass joints
Frameless glass corners and panels are joined with silicone. We reseal with a suitable glazing silicone.
Shower screens
A screen’s wall joint and tray joint are where leaks start. Both are resealed with anti-fungal silicone.
Frames and glazing around Cranmore
Cranmore is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on glazing joints and frame seals, especially on the side facing the sea. With historic houses such as Swainston Manor (about 3.4 miles south-east) nearby, there’s older building stock in the area around Cranmore as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Swainston Manor, about 3.4 miles south-east, is one of the historic houses in the wider area around Cranmore. Managing a site like Shalfleet Church of England Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.

What’s near Cranmore

Why deal with it now?
A new conservatory roof is a big job. Where the water is getting in through sealant renewing the joint is the simpler fix. If it’s the roof itself, we will tell you. In a small place like Cranmore, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.

- Domestic, commercial and hotel work
- Anti-fungal silicone where joints get wet
- Colour agreed with you before any work starts

How the visit works

The visit itself normally takes anything from an hour or two to most of a day, depending on the size of the job, depending on the size of the job. Somewhere as small as Cranmore, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we check where the water gets in.
- We remove the old sealant carefully.
- We clean the glass and frame so the new silicone bonds.
- A neutral-cure glazing silicone is applied and tooled.
- Each joint is checked and, where possible, water-tested.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Move anything stored near the joints
- Mention any tricky access

Cranmore questions
Is glazing silicone in a coastal place like Cranmore any different?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Do you cover smaller places like Cranmore?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Will there be a smell?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
Is the work guaranteed?
All our work has a 12-month guarantee, and we are fully insured.
Can you fix a leaking conservatory?
It depends on the cause. Failed glazing and frame joints can be resealed but roof and panel problems need another trade.
Should I try DIY first?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Why not top up the existing silicone?
It does not last. The new bead can’t grip the old one so we take it all out and start clean.
Should I try it myself first?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Stick to mild cleaners on glass
- Inspect the sealant on glazing annually
- Act on drips or damp patches early
- Run a squeegee over the glass when you’re done
Clear the conservatory gutters regularly so water does not back up against the seals. Blocked gutters can push water where it shouldn’t go.
Don’t leave lifting or mouldy silicone on glazing. Once it starts to peel, water gets behind it and the problem grows.
