Sand mastic in Church Town, done properly
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 work on brick reveals, sash and case windows and tenement windows, and the jobs we see most are mastic dropping out of the joint and modern sealant on a period surround.
Homes in small places like Church Town 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.
Every job comes with our 12-month guarantee.

What happens on the day
There is not much for you to do on the day. Show us the job and we will take it from there. The job generally takes anything from a few hours to a full day, depending on how many windows, including the tidy-up. For a village or hamlet like Church Town, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
Ask for a quote
Call for a quick quote, or send an email if you’d rather. Tell us about the joints that need doing and we will explain what’s involved before giving you a price.
Advice
Signs you need sand mastic in Church Town
Timber frames move with the seasons. That movement opens up the mastic joint little by little.
Look out for these signs:
- Gaps round a timber door in stone or brick
- Old sand mastic that has cracked, crumbled or fallen out
- Gaps where the frame meets the masonry
- Old cement repairs round a window that have failed
Homes close to Church of St Nicholas include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
Before you book anyone
- Whether all the old sealant comes out first
- How the colour is chosen
- Whether they’re fully insured
- How the joint is cleaned and prepared
What affects the quote in Church Town
The quote reflects the job in front of us. We look at:
- Working hours on commercial sites
- Whether the work is at height
- The amount of work
- Which sealant suits the joint
Combining jobs into one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.
What we need to know
Photos help, but a description is a good start. Try to tell us:
- Photos by email, if that is easy
- The type of property
- Access, such as stairs, a lift or height
- How many joints, rooms or windows are involved
Getting a quote is simple: let us know the job and the location. A few photos by email make the job easier to understand, and we will come back to you with a quote.
Looking after it afterwards
Aftercare is simple:
- Ask the planning authority about consent for listed or conservation-area homes
- Sort the mastic before the decorators arrive
- Take care around the mastic when scraping paint
- Avoid patching sand mastic with silicone
Keep gutters and sills clear so water runs away from the surround. Water sitting against the mastic shortens its life.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
When something else is needed
Sealant is not the answer to every problem, and we’ll tell you before work begins. Sealant will not put right:
- Crumbling stone or brickwork round the window
- Putty and glazing repairs
- Sashes that rattle, stick or won’t open
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.

Church Town homes and the weather
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Titsey Place (about 3.8 miles north-east) are a reminder that the area around Church Town 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 is traditional sand mastic.
Rented homes near Godstone station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. For site and facilities teams at buildings such as Godstone Village School, larger buildings have plenty of frames, and the mastic around each one ages.
