How we handle glazing silicone in Crowmarsh Gifford
Glazing joints need a sealant made for glass. Our applicators use neutral-cure glazing silicone, which suits glass and most frame materials, and we tool it to a neat, even finish. We work on conservatory frames, rooflights and shower screens, and the jobs we see most are mouldy sealant around glass panels and leaking glazing joints on a rooflight.
Mastic can only go onto a dry, clean joint, so window work in Crowmarsh Gifford is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Each job carries a 12-month guarantee, large or small.

Crowmarsh Gifford: your questions answered
Can you do glazing silicone in Crowmarsh Gifford?
Yes, Crowmarsh Gifford is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or email us and let us know what needs doing, and we will give you a clear quote.
Do you cover smaller places like Crowmarsh Gifford?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Do you reseal glass shower screens?
Yes. We remove the old sealant and reseal the wall and tray joints.
How long does glazing silicone take?
A typical job takes a few hours for most jobs, including preparation and clearing up. Your quote will say how long we expect yours to take.
Do the sealants smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
Is the work guaranteed?
You get our 12-month guarantee on all our work.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Work for landlords, hotels and businesses
If you manage several properties in or around Crowmarsh Gifford, several properties can be quoted together. Just tell us the addresses and what each one needs.
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Leave it or put it right?
Replacing windows or a shower screen is not needed for a failed joint. Sound glass and frames usually just need resealing, and we will tell you if that’s not the case. Where a wall is exposed, as many are in small places like Crowmarsh Gifford, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.

Crowmarsh Gifford homes and the weather
With historic houses such as Brightwell Manor (about 2.7 miles west) nearby, there’s older building stock in the area around Crowmarsh Gifford as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. London and the South East are among 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 Crowmarsh Gifford Church of England School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. Rented homes near Cholsey station change hands often, and glazing joints are worth checking at the end of a tenancy, before a small leak grows. Homes close to Church of St Mary Magdalene include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Should I try it myself first?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What we cannot put right
We will always be straight with you, so here’s what sealant can’t fix:
- A frame that needs repairing or replacing
- Water coming through the roof rather than a sealant joint
- A sealed unit that has misted inside
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly.
