How we handle sand mastic in Weston
On many period windows, sand mastic looks right and suits the building. On modern frames we’d normally use a flexible sealant, and we will talk through which suits your home. Typical jobs include mastic worn away on windows facing the weather and silicone on a period window that looks wrong, across timber door frames, stone surrounds and tenement windows.
Outdoor sealant needs dry, clean surfaces, so work on frames around Weston is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
All our work comes with our one-year guarantee.

Work for landlords, hotels and businesses
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Renew mastic before redecorating the windows
- Check with your local planning authority if your home is listed
- Take care around the mastic when scraping paint
- Ask a joiner to look at soft timber first
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
Once mastic starts to crumble, rain gets in. That water can reach the timber frame and the wall so early renewal protects both.

DIY versus a professional finish
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.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

Why deal with it now?
Filling over old, loose mastic does not last. Raking out and preparing the joint gives it a sound base so the new work lasts. In a small place like Weston, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.
What you get with us

What sand mastic looks like in Weston
Historic houses like Benham Park (about 4.7 miles south-east) are a reminder that the area around Weston 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. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to St Thomas' Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Letting a property close to Kintbury station? Then any sash windows need sound mastic to keep draughts and rain out.
