How we handle sand mastic in Whitehawk
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’re often asked to deal with cement or filler used on old window joints that has cracked and old sand mastic that has cracked, crumbled or fallen out, on stone surrounds, brick reveals and sash and case windows.
In smaller places like Whitehawk, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. The right sealant depends on the frame and on what it sits in.
All of our work is guaranteed for twelve months, in Whitehawk and everywhere else we cover.

Whitehawk homes and the weather
Whitehawk is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around older windows and doors, especially on the side facing the sea. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Schools such as City Academy Whitehawk are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. If you live in an older home near St Cuthman's, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

How it works
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. It generally takes a few hours per window, depending on the condition of the joints. For a job in Whitehawk, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- Each surround is checked first.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic isn’t too thick.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
How to prepare
- Move anything stored near the joints
- Where the joints are inside, avoid wetting them before we arrive
- Plan for the work area to be out of bounds to pets and children

Why it’s worth doing now in Whitehawk
Draughts round a sash window aren’t always the sashes. Open mastic joints round the box can let air in, and renewing the mastic closes them. In a smaller place like Whitehawk, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
What it costs depends on how much there is to do, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts.
Why us?
- More than 20 years in sealant work
- An ARBOMaster approved applicator

DIY versus a professional finish
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.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
