How we handle sand mastic in Hyde
Burnt sand mastic is a traditional material that sits naturally against stone and brick. It’s a good fit for period properties where a modern sealant bead would stand out. We work on period & listed homes, sash and case windows and timber door frames, and people most often call us about draughts and rain around sash boxes and old sand mastic that has cracked, crumbled or fallen out.
In a village or hamlet like Hyde, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Different surfaces, different methods
Stone surrounds
We take care not to mark the stone when the old mastic comes out.
Sash and case windows
On a sash window, the mastic joint shows on the outside, so a neat, even finish matters.
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 mastic stays put. Where a wall is exposed, as many are in small places like Hyde, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Combining jobs into one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. We will give you a clear quote for the lot.

Should I try it myself first?
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.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

For a quick quote, just ask. What matters most is:

How it works
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take a few hours per window, depending on the condition of the joints. For a village or hamlet like Hyde, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.
Getting ready for the visit
- For business premises, tell us about site rules or sign-in
- Mention any leaks or damp you’ve noticed
- Tell us if parking is tricky

Sand mastic in Hyde: local notes
Historic houses like Breamore House (about 4.4 miles north) are a reminder that the area around Hyde has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. 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.
Schools such as Hyde Church of England Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Do you need sand mastic in Hyde?
Timber swells and shrinks with the weather. The movement cracks the mastic over time.
Common reasons people contact us include:
- Wind and rain getting in round a sash window
- Crumbling sand mastic round a window
- Cement or filler used on old window joints that has cracked
- Modern sealant on a period surround
If you live in an older home near Church of the Holy Ascension, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Common questions in Hyde
Do you cover smaller places like Hyde?
Yes, Hyde is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
What guarantee comes with sand mastic in Hyde?
Every job comes with our 12-month guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Can I do it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Is it OK to seal over old sealant?
No, it won’t last. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Is consent needed for window work on a listed home?
Speak to your local planning authority before work starts. Sand mastic is often favoured as like for like but the decision is theirs.
Is sand mastic better than silicone for my windows?
Sand mastic normally suits period timber windows best. Modern frames normally suit a flexible sealant.
Which products do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll tell you what we’re using.
