Sand mastic in West Hoathly, done properly
On many period windows, sand mastic looks right and suits the building. Newer frames generally get a flexible sealant instead and we’ll explain which is best for yours. Common call-outs are for mastic worn away on windows facing the weather and silicone on a period window that looks wrong, across tenement windows, sash and case windows and brick reveals.
Homes in small places like West Hoathly often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

West Hoathly homes and the weather
With historic houses such as Priest House (about 0.2 miles south-west) nearby, there’s older building stock in the area around West Hoathly as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
Managing a site like West Hoathly CofE Primary School? Then the mastic around its windows and doors needs looking after like any other building’s. In the older streets around St Margaret's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Should I try it myself first?
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 heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

The job usually takes anything from a few hours to a full day, depending on how many windows, and we tell you how long to leave it before we go.

What we can’t put right
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Timber that has rotted
- Cracked or broken glass
- Decisions on consent for listed homes
If in doubt, call 0345 464 0079 or send us an email and we will say what we think.
What we seal
- Sash and case windows
- Stone surrounds
- Period & listed homes
- Tenement windows
- Brick reveals
- Timber door frames
Leave it or put it right?
Not every draught comes from the sashes themselves. Open mastic joints round the box can let air in, and renewing the mastic closes them. Around West Hoathly, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please phone 0345 464 0079 or send us an email and we’ll talk you through it.
