How we handle sand mastic in Hampton Hill
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s a mix of sand and a linseed-oil-based binder, applied by hand. On period homes, it looks right where silicone wouldn’t. If you’re dealing with mastic that needs renewing before redecorating and draughts and rain around sash boxes, we can put it right, on period & listed homes, timber door frames and brick reveals alike.
From mansion-block windows to modern glazing in new flats, London has every kind of frame. Over the years, the sealant around them shrinks, cracks and pulls away, letting in draughts and water.
All of our work is guaranteed for twelve months, in Hampton Hill and everywhere else we cover.

What do you put in the joint?
Products from Arbo and Everbuild, among others, picked for each joint. We will tell you what we’re using and why.
Do I need to be at home?
Access is agreed with you when the job is booked. Indoors, that usually means someone at home.
Is it messy?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.

Yes. We are fully insured.
Do you need sand mastic in Hampton Hill?
Sand mastic slowly weathers. It dries out, cracks and loses its grip on the stone or timber.
The most common problems we see are:
- Crumbling sand mastic round a window
- Gaps where the frame meets the masonry
- Draughty sash windows at the surround
- Silicone on a period window that looks wrong
For site and facilities teams at buildings such as Hampton Hill Junior School, its window and door frames need their mastic kept sound, just like a home’s.

What we do, step by step

Mention any building rules, key holders or managing agents when you book.
- First, we look at the surrounds with you and agree what needs doing.
- Old, loose mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The mastic is finished to sit tidily against the stone or brick.

Aftercare tips
After the cure time, these simple habits help:
- Ask the planning authority about consent for listed or conservation-area homes
- Plan mastic work ahead of painting
- Do not paint over the new mastic
- Ask a joiner to look at soft timber first
When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.

What sand mastic looks like in Hampton Hill
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Strawberry Hill House (about 1.2 miles north-east) nearby, there’s older building stock in the area around Hampton Hill 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.

DIY versus a professional finish

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
