Braywoodside Window Mastic
Window mastic for Braywoodside, by sealant specialists with 20+ years’ experience. Rated 4.9 on Google from 180+ five-star reviews.

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 chosen for how the joint moves and where it is.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Window mastic for homes and businesses in Braywoodside
If you can feel air around a shut window, the gap is often at the frame. A new joint stops the air getting through. If the draught is through the window seals instead, we’ll tell you. We work on timber windows & doors, composite doors and aluminium frames, and the jobs we see most are hard, cracked sealant around windows and draughty joints inside around the window.
Outdoor sealant needs dry, clean surfaces, so work on frames around Braywoodside is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
There’s a 12-month guarantee on every job, whatever its size.

Common questions in Braywoodside
Can you do window mastic in Braywoodside?
Yes. Our work covers London and the South East, and Braywoodside is part of that. Just call 0345 464 0079 or email us with a few details of the job.
Can you help a landlord with a rental near Maidenhead station?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Does the work come with a guarantee?
Yes. All our work carries a 12-month guarantee, and we’re ARBOMaster approved applicators.
Can you seal over the old sealant?
No, it will not last. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Can you reach windows above the ground floor?
Yes, where they can be reached safely. Tell us about access when you get in touch and we’ll plan for it.
Will new mastic stop draughts?
If the draught is coming in around the frame, yes. If it’s through the window’s own seals or a hinge, that is a different fix, and we’ll say so.
Do the sealants smell?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
Where are you based?
We are a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Work for landlords, hotels and businesses
Housing providers, facilities teams and property managers book us too in Braywoodside and across Windsor and Maidenhead. Several sites can go on one quote, and we’re fully insured for the work.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
What the job involves on each surface
Window sills
Stone and concrete sills have their own joints, and the joint under the frame can let rain run behind. Those are sealed with a product suited to stone or concrete.
Timber windows & doors
Soft or rotten wood can’t be sealed successfully. If we find rot, we’ll tell you before going ahead, as a joiner will need to deal with it.

Why it’s worth doing now in Braywoodside
Resealing frames is a short job: the visit takes a few hours for a handful of frames, longer for a whole house. Leave it until water is coming in and you may need plastering and decorating as well. In a small place like Braywoodside, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we’ll go through it with you.
What you get with us
- More than 20 years in sealant work

Windows and doors in Braywoodside
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Dorney Court (about 3.8 miles north-east) are a reminder that the area around Braywoodside has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Dorney Court, about 3.8 miles north-east, is one of the historic houses in the wider area around Braywoodside, and older homes nearby need a sealant that suits their walls. Letting a property close to Maidenhead station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

What we’re called out for in Braywoodside
Sills take more water than any other part of a window, so the sill ends and the joint below the frame are common leak points. Failed sealant there lets rain into the wall or behind the frame.
Keep an eye out for any of the following:
- Hard, cracked sealant around windows
- Old mastic that has gone black or come away
- Rushed sealant from a window installation
- Sealant in the wrong colour for the frame
If you look after a building such as Holyport College, its window and door frames need their mastic kept sound, just like a home’s.
