Why deal with it now?
Filling over old, loose mastic doesn’t last. Raking out and preparing the joint gives it a sound base so the new mastic stays put. Around Stocking Pelham, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
Why book with us
- Any old sealant cut out fully, not covered over

About our sand mastic in Stocking Pelham
Traditional burnt sand mastic 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 tenement windows, brick reveals and timber door frames, and common reasons people get in touch are patchy fillers round a sash window and mastic dropping out of the joint.
Somewhere as small as Stocking Pelham, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.

How long does sand mastic take?
As a guide, most jobs take a few hours for a single window, longer for several. Larger jobs naturally take longer.
Can you replace silicone on a period window with sand mastic?
Usually, yes. Once the silicone is out and the joint prepared we point it with sand mastic.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Can I choose the sealant colour?
We help you choose a colour that suits, from white and clear to greys and other shades. The product needed can limit the range.
Should I use sand mastic or silicone?
For period timber windows in stone or brick, sand mastic is often the better fit. Modern frames normally suit a flexible sealant.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.

We work for landlords and letting agents as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.

Advice
Signs you need sand mastic in Stocking Pelham
Timber swells and shrinks with the weather. The movement cracks the mastic little by little.
Any of these means the joints need attention:
- Gaps where the frame meets the masonry
- Gaps round a timber door in stone or brick
- Draughts and rain around sash boxes
- Old sand mastic that has cracked, crumbled or fallen out
For an older house near a landmark such as Church of St Mary, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

- Which sealant they’ll use, and why
Can I do it myself?
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.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Inspect the joints round the windows every year or so
- Avoid patching sand mastic with silicone
- Check with your local planning authority if your home is listed
- Take care around the mastic when scraping paint
Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look rather than patching it.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.
