Common questions in West Cliffe
Do you cover smaller places like West Cliffe?

I let a flat near Martin Mill station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Can sand mastic be painted?
Traditional guidance is not to paint over sand mastic. Ask us before you decorate around it and we will advise.
How long does sand mastic take to go off?
The surface skins quite quickly and it hardens fully over a longer time. The weather and joint depth both affect it.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Does someone need to be in?
Access is agreed with you when the job is booked. Indoors, that normally means someone at home.
Will there be a smell?
It depends on the product. Some products have a noticeable smell, others very little.
Is it possible to take out silicone and use sand mastic instead?
Normally, yes. With the silicone removed and the joint cleaned, sand mastic is applied by hand.
Sand mastic in West Cliffe
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s a mix of sand and a linseed-oil-based binder and built up by hand. On period homes, it looks right where silicone wouldn’t. We work on timber door frames, period & listed homes and sash and case windows, and people most often call us about weathered mastic on the most exposed windows and old cement repairs round a window that have failed.
Outdoor sealant needs dry, clean surfaces, so work on frames around West Cliffe is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
Big or small, you get the same 12-month guarantee.

DIY versus a professional finish
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What we are called out for in West Cliffe

How to look after the new joints
After the cure time, these simple habits help:
- Ask a joiner to look at soft timber first
- Avoid heavy scraping on the mastic joint
- Renew mastic before redecorating the windows
- Do not run silicone over sand mastic
When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.
Different surfaces, different methods
Stone surrounds
Old stone surrounds are often uneven, so the joint varies in width. Sand mastic is shaped by hand to suit.
Period and listed homes
A traditional finish suits a period property, and sand mastic is one of them.
What sand mastic looks like in West Cliffe
West Cliffe 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. Historic houses like Walmer Castle (about 3.8 miles north-east) are a reminder that the area around West Cliffe has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Managing a site like St Margaret's-at-Cliffe Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. If you live in an older home near Church of St Peter, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Why act early in West Cliffe
Gaps round a sash window let in rain and draughts. Left, water can reach the timber and the wall, so dealing with it now protects both. Where a wall is exposed, as many are in small places like West Cliffe, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or send us an email.
