About our sand mastic in Chilton Green
Fresh sand mastic forms a skin quite soon, but it takes longer to harden fully. Traditionally, sand mastic is left unpainted, so ask us before you decorate. Typical jobs include modern sealant on a period surround and mastic worn away on windows facing the weather, on stone surrounds, brick reveals and period & listed homes.
Around Chilton Green, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
Your job is guaranteed for a year, as with all our work.

How it works
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. It normally takes a few hours for a single window, longer for several. In a small place like Chilton Green, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
Before we arrive
- On commercial sites, let us know about site rules
- For indoor joints, keep the area dry beforehand if you can
- Mention any parking rules near the property

What we are called out for in Chilton Green
Shallow joints are a common cause. A thin layer does not hold well, which is why we pack deep voids first and get the depth right.
Most people get in touch after spotting one of these:
- Mastic dropping out of the joint
- Wind and rain getting in round a sash window
- Mastic worn away on windows facing the weather
- Gaps where the frame meets the masonry
Managing a site like Brighstone Church of England Aided Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.

Why it’s worth doing now in Chilton Green
Cement-based fillers and modern sealants do not always suit a period surround. Sand mastic matches what was there, which can matter on listed and conservation-area homes. Where a wall is exposed, as many are in small places like Chilton Green, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

Sand mastic in Chilton Green: local notes
Chilton Green is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. 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.
If you live in an older home near St Peter and St Paul's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Keeping the joints in good condition
After the cure time, these simple habits help:
- Plan mastic work ahead of painting
- Look over the window mastic once a year
- Keep modern sealant off the mastic
- Find out about consent before window work on a listed home
Do not run silicone over the new mastic. If you see a crack, ask us to take a look rather than patching it.
Once mastic starts to crumble, rain gets in. That water can reach the timber frame and the wall, so renewing it early is worth it.
Chilton Green questions
Do you cover Chilton Green for sand mastic?
Yes, Chilton Green is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or send us an email and tell us what needs doing, and we’ll send you a clear quote.
Does the coastal weather in Chilton Green affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Will it make a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Can landlords and businesses book you?
Yes, often. We can quote for several properties at once, and between tenancies is a good time for the work.
Do you offer different sealant colours?
We will suggest a colour to suit the surroundings. The product needed can limit the range.
Do you have insurance?
Yes. We’re fully insured.
What does sand mastic cost?
Every job is different, so each one gets its own quote. For a quick quote, phone 0345 464 0079 or email us and let us know what needs doing and where.
Which is right for my windows, sand mastic or modern sealant?
That depends on your windows. Period windows in stone or brick usually suit sand mastic and newer frames usually get a flexible sealant.
