Sand mastic in Westbrook
For a listed home or one in a conservation area, ask your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. We’re often asked to deal with cement or filler used on old window joints that has cracked and silicone on a period window that looks wrong, across sash and case windows, tenement windows and period & listed homes.
Around Westbrook, conservatories, garden rooms and patio doors are often part of the house. Their glazing joints and frame seals are as much a part of the job as the windows, and any older timber or sash windows need a sealant that suits them.
There’s a 12-month guarantee on every job.

Why act early in Westbrook
An open joint round the frame lets weather in. Water can get to the frame and the masonry, so dealing with it now protects both. Around Westbrook, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
Doing several joints on one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

When to call us in Westbrook
Timber frames move with the seasons. The movement cracks the mastic little by little.
It’s worth asking for a quote if you see:
- Mastic worn away on windows facing the weather
- Cement or filler used on old window joints that has cracked
- Draughts and rain around sash boxes
- Mastic that needs renewing before redecorating
Schools such as Garlinge Primary School and Nursery are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.
What to look for in a quote
- What happens if the job turns out different
- Which sealant they’ll use, and why

How it works
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. Once we’ve agreed what’s being done, we protect the area and start. It normally takes a few hours for a single window, longer for several. In a smaller place like Westbrook, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic is not too thick.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
Getting ready for the visit
- Mention if the joints have been sealed before
- Clear items away from the joints we are working on
- Try not to wet indoor joints just before the visit

Advice
Windows and doors in Westbrook
Westbrook is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Homes close to Church of All Saints include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in. Letting a property close to Margate station? Then any sash windows need sound mastic to keep draughts and rain out.
