Sand mastic in Slough Green
On many period windows, sand mastic looks right and suits the building. On modern frames we’d normally use a flexible sealant, and we’ll talk through which suits your home. We work on brick reveals, sash and case windows and tenement windows, and common reasons people get in touch are window mastic to renew ahead of painting and old cement repairs round a window that have failed.
Outdoor sealant needs dry, clean surfaces, so work on frames around Slough Green is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.

Sand mastic in Slough Green: local notes
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Tyes Place (about 1.3 miles north) are a reminder that the area around Slough Green 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.
Managing a site like Warden Park School? Then the mastic around its windows and doors needs looking after like any other building’s. Tyes Place, about 1.3 miles north, is one of the historic houses in the wider area around Slough Green. Rented homes near Balcombe station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.

How it works
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The work itself takes a few hours per window, depending on the condition of the joints, including the tidy-up. In a small place like Slough Green, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each surround is checked first.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic is not too thick.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- On commercial sites, let us know about site rules
- Plan for the work area to be out of bounds to pets and children

DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
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.
How the job changes by surface
Stone surrounds
Stone surrounds suit sand mastic well. It finishes to look like part of the surround.
Brick reveals
Gaps between frame and brick let in rain and draughts. New mastic seals the gap.
How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Ask the planning authority about consent for listed or conservation-area homes
- Ask a joiner to look at soft timber first
- Take care around the mastic when scraping paint
- Avoid patching sand mastic with silicone
Leave the new mastic unpainted, which is the traditional advice. Ask us before any decorating around it.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.
Work for landlords, hotels and businesses
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will quote.
