How we handle sand mastic in Low Street
Burnt sand mastic is a traditional material that sits naturally against stone and brick. It suits period and listed homes where a modern sealant bead would stand out. We work on sash and case windows, period & listed homes and tenement windows, and the jobs we see most are gaps round a timber door in stone or brick and patchy fillers round a sash window.
Outdoor sealant needs dry, clean surfaces, so work on frames around Low Street is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Low Street: your questions answered
Will you come out to Low Street?
Yes, Low Street is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Does living near the coast affect sand mastic in Low Street?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Where are you based?
We work from Crawley. We cover Low Street and the rest of Thurrock.
Will there be a smell?
There can be a smell while the sealant cures. Opening a window helps.
How long will you be here?
Most jobs take a few hours per window, depending on the condition of the joints. Your quote will say how long we expect yours to take.
Is it possible to paint over sand mastic?
It’s traditionally left unpainted, as guidance on traditional windows advises. Ask us before decorating.
Do I need to be at home?
We need access to the joints, so we will agree that with you when we book. Indoors, that normally means someone at home.
What should I tell you?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply ring 0345 464 0079 or send us an email.

How the visit works
There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the work takes a few hours for a single window, longer for several for a typical job. For a village or hamlet like Low Street, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- Large voids are packed out.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.

What sand mastic looks like in Low Street
Low Street is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around older windows and doors, especially on the side facing the sea. 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.

Why act early in Low Street
Before painting the windows, it pays to renew the mastic. Painting over failed mastic doesn’t seal it and traditional guidance is to leave the new mastic unpainted. Older cottages and farmhouses around Low Street can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference.
Why book with us
- Anti-fungal sanitary silicone in wet areas
- Homes, businesses and hotels
- Every job guaranteed for a year
- More than 20 years in sealant work

What we are called out for in Low Street
Decorating can disturb tired mastic. It’s often found when windows are being prepared for paint, which is a good time to renew it.
People generally contact us when they notice something like this:
- Mastic dropping out of the joint
- Mastic round period door frames that has failed
- Tired mastic found when preparing windows for paint
- Old cement repairs round a window that have failed
Homes close to St James' Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Questions to ask before you book
- How hidden problems are handled
- Who turns up on the day
- What product goes in the joint
- How the surfaces are prepared before sealing
How to look after the new joints
Aftercare is simple:
- Don’t paint over the new mastic
- Get any rot dealt with first
- Go gently near the mastic when preparing windows
- Clear gutters so water does not pour onto the windows
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
Sound mastic protects the frame. Once it fails, water can sit against the timber and timber that stays wet can rot.
