Glazing silicone in Crayford, 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. If you are dealing with leaks where conservatory glass meets the frame and rooflight joints letting water in, we can help, whatever the surface.
Homes around Crayford range from older properties to newer houses, and their windows range just as widely. The right sealant depends on the frame and on what it sits in.
Whatever the size of the job, you get the same one-year guarantee.

Different surfaces, different methods
Conservatory frames
Conservatory frame joints are a common source of leaks. We remove the failed sealant and renew it.
Rooflights
Rooflights get the full force of the weather. Its sealant ages faster than vertical joints.
Why deal with it now?
A leaking joint won’t fix itself. Water can damage frames, walls, flooring and furniture, so it pays to deal with it early. Around Crayford, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.

Quotes for glazing silicone in Crayford

- Any working-time requirements on site
- Mould in or behind the old joints

There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.
What we need to know
There’s no need for technical detail. It helps if you can tell us:
- Photos by email, if that is easy
- Roughly how big the job is
- Whether it has been sealed before
- Where the job is, and your postcode
Getting a quote is simple: let us know the job and the location, and roughly how big it is. A few photos by email make the job easier to understand, and we will take it from there.
Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Ventilate the conservatory to cut condensation
- Act on drips or damp patches early
- Run a squeegee over the glass when you’re done
- Inspect the sealant on glazing annually
Avoid scraping near the new silicone when you clean. A soft cloth or sponge is best.
If silicone on glass has cracked, water is already getting in. Resealing now is a small job compared with fixing water damage later.

Glazing silicone in Crayford: local notes
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. With historic houses such as Hall Place and Gardens (about 0.9 miles west) nearby, there’s older building stock in the area around Crayford 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 live in an older home near Church of St Paulinus, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Rented homes near Crayford station change hands often, and glazing joints are worth checking at the end of a tenancy, before a small leak grows.

Silicone won’t bond to a dirty surface. Where the joint wasn’t cleaned and degreased, the bead can peel away early.
People usually contact us after spotting something like this:
- Glass-to-glass joints that have split
- New silicone smeared over old sealant
- Leaks where conservatory glass meets the frame
- Black or yellowed silicone on glass joints
Schools such as Wentworth Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.
