Your questions about window mastic in Yateley
Is there a guarantee on window mastic in Yateley?
All our work, in Yateley and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Can you do window mastic in Yateley?
Yes. We work across London and the South East, and Yateley is part of that. You can phone 0345 464 0079 or send us an email and let us know what needs doing.
Do I have to be there?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Do you seal inside as well as outside?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We can do either or both.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Is the new sealant paintable?
That depends on the product. Some hybrid sealants can be painted; silicone cannot. Tell us if you’re decorating and we’ll choose accordingly.
I rent my home. Can I book you?
Yes. Check with your landlord; we can send the quote to them too.
What do you put in the joint?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
About our window mastic in Yateley
Colour matters on a frame. White, brown, anthracite grey, black and clear sealants are all available, so the line suits the frame instead of standing out. Common call-outs are for damp patches on the reveal after heavy rain and cracked sealant at the sill ends, across composite doors, uPVC windows and aluminium frames.
Around Yateley, many houses have gained conservatories, French doors or replacement windows over time. Each one adds more joints to look after, and those joints age at different rates. Sills, frame heads and glazing joints are where leaks usually start.
All of our work is guaranteed for twelve months, in Yateley and everywhere else we cover.

What happens if it’s left?
Resealing frames is a short job: it takes most of a day for a typical house, less for a few frames. Wait for damp to appear and there may be plaster and decorating to sort out too. Gaps in sealant and mould in the bead never get better on their own, and in a busy household in Yateley they spread with every shower and every downpour. Replacing the sealant now is the simplest fix.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

What happens on the day
The work is kept neat and contained to the joints we are treating, so you can get on with your day. The job normally takes a morning for a couple of windows and a door, and we tell you how long to leave it before we go. In Yateley, parking is rarely complicated, though it helps to know about driveways or restrictions, and mention if the work is upstairs, in a flat or high on the outside.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
How to prepare
- Clear the area around the work
- Where the joints are inside, avoid wetting them before we arrive
- Mention any tricky access

Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
Common problems we fix in Yateley
Joint shape matters as much as the product. A skim of sealant over a wide gap soon tears, while a joint packed solid cannot stretch. That’s what backing rod is for.
Signs it’s time to call us include:
- Rushed sealant from a window installation
- Mastic that has split away from the wall
- A bead that does not match the frame
- Leaking joints at the ends of sills
For site and facilities teams at buildings such as Yateley School, larger buildings have plenty of frames, and the mastic around each one ages.
Questions to ask before you book
- Who turns up on the day
- What guarantee comes with the work
- Whether VAT is included
- Which sealant they’ll use, and why

Windows and doors in Yateley
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.
Rented homes near Sandhurst station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. In the older streets around Church of St Peter, the joint between an old wall and a newer frame is generally the first place rain gets in.

Surface by surface
Composite doors
Composite doors are normally hung in an uPVC-type frame, so its perimeter joint is sealed much like a window. We match the colour to the frame.
uPVC windows
uPVC expands and contracts noticeably with temperature, so we use a flexible, low-modulus sealant. We match white, brown, anthracite grey and black frames.
