Sand mastic for homes and businesses in Brookland
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 older homes, it suits the building far better than silicone. We work on sash and case windows, tenement windows and timber door frames, and people most often call us about gaps between timber frames and stone or brick and failed mastic on an exposed elevation.
Mastic can only go onto a dry, clean joint, so window work in Brookland is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
All of our work is guaranteed for twelve months.

Landlords, agents and businesses in Brookland
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
We also work for property managers and facilities teams in Brookland and across Kent. We can quote a run of properties together.
What happens if it’s left?
Replacing sash windows is a big decision for a period home and on a listed home, consent may be needed. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Where a wall is exposed, as many are in small places like Brookland, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we’ll explain what it covers.

Signs you need sand mastic in Brookland
Previous repairs in cement or silicone often trap water or crack away. They do not move with the timber, and they normally need raking out.
The problems people usually mention when they call include:
- Mastic dropping out of the joint
- Silicone on a period window that looks wrong
- Weathered mastic on the most exposed windows
- Patchy fillers round a sash window
If you live in an older home near St Augustine's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
What your quote should include
- Whether all the old sealant comes out first
- The length of the guarantee
- Which sealant they’ll use, and why
- How hidden problems are handled
Frames and glazing around Brookland
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Schools such as Brookland Church of England Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. Letting a property close to Appledore (Kent) station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about.

Around Brookland
We work in homes and buildings around The Royal Oak Inn. The closest station to Brookland is Appledore (Kent) station, roughly 2.5 miles north of the centre.

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Take care around the mastic when scraping paint
- Make sure water runs off the sill
- Look over the window mastic once a year
- Get any rot dealt with first
Don’t run silicone over the new mastic. If you see a crack, ask us to take a look before trying a quick fix.
Sound mastic protects the frame. Once it fails, water can sit against the timber, which can lead to rot.
What sealant work cannot fix
Some problems need a builder, plumber or other trade rather than us:
- Damaged stone surrounds
- Rotten sashes, sills or window boxes (a joiner’s job)
- Sashes that need overhauling
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think.
What we seal

What else we do in Brookland
Brookland questions
Will you come out to Brookland?
Yes, Brookland is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Appledore (Kent) station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or send us an email and tell us about the property, and we will send you a clear quote.
Is consent needed for window work on a listed home?
Your local planning authority is the one to ask. They decide whether consent is needed.
Can I choose the sealant colour?
Usually, yes. White, clear and grey are common, and other colours are available for many products, and we will agree it with you first.
Do I have to be there?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
What does sand mastic cost?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Are you insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Can I paint the new mastic?
Sand mastic is normally left unpainted, as guidance on traditional windows advises. Talk to us before any painting near it.
How the visit works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a single window, longer for several, and the area is left clean. Somewhere as small as Brookland, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- Large voids are packed out.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
Getting ready for the visit
- Keep children and pets away from the work area
- Try not to wet indoor joints just before the visit
- Tell us about any previous sealing or DIY attempts
