What is sand mastic?
It’s the traditional filler for the joint round timber windows and doors. It’s made with sand and a linseed-oil-based binder.
How we handle sand mastic in Reigate
Sand mastic doesn’t last for ever and gaps open up round the frame. We rake it out and renew it so the surround looks right again. If you have gaps where the frame meets the masonry and modern sealant on a period surround, we can put it right, whatever the surface.
Reigate mixes older streets, where windows have often been replaced, with newer estates fitted with uPVC. In every case, the joint between frame and wall is what keeps water out.
A 12-month guarantee comes as standard.

Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Letting a property close to Reigate station? Then any sash windows need sound mastic to keep draughts and rain out. If you live in an older home near Church of St Mary Magdalene, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What else we do in Reigate
How it works
We keep the work tidy and contained to the area we are working on, so you can carry on as normal. Expect the work to take anything from a few hours to a full day, depending on how many windows, and we explain the cure time before we leave. A visit in Reigate needs access to the work and a place to park close by. For outside work, let us know about side access, gates and any upper-floor joints.
- We check the window surrounds and agree which joints need renewing.
- Old, loose mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The finish is dressed so it sits neatly against the stone or brick.
How to prepare
- Mention any leaks or damp you’ve noticed
- For business premises, tell us about site rules or sign-in
- Try not to wet indoor joints just before the visit

Landlord and commercial work in Reigate
In hotels, rooms out of use cost money, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What sealant work cannot fix
We will not take on work that will not last, so here’s what sealant cannot put right:
- Cracked or broken glass
- Masonry that needs repairing
- Decayed frames that need repair
If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before booking.
Joints and surfaces we work on
- Stone surrounds
