Sand Mastic in Painters Ash

What happens on the day
Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a single window, longer for several. For a job in Painters Ash, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic isn’t too thick.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive

About our sand mastic in Painters Ash
On many period windows, sand mastic looks right and suits the building. Newer frames usually get a flexible sealant instead, and we will talk through which suits your home. Common call-outs are for failed mastic on an exposed elevation and gaps where the frame meets the masonry, across timber door frames, period & listed homes and stone surrounds.
In smaller places like Painters Ash, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. Each frame material needs the right sealant against the right wall.
Every job is covered by a 12-month guarantee.

What sand mastic looks like in Painters Ash
Painters Ash is within about 3 miles 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. 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.
Schools such as Painters Ash Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around Church of All Saints, the joint between an old wall and a newer frame is normally the first place rain gets in.

Your questions about sand mastic in Painters Ash
Will you come out to Painters Ash?
Yes. Painters Ash is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is sand mastic in a coastal place like Painters Ash any different?
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.
Should I check with the council before work on a listed or conservation-area home?
It’s best to ask your local planning authority first. Sand mastic is often favoured as like for like, but they decide.
I rent my home. Can I book you?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Is sand mastic better than silicone for my windows?
That depends on your windows. Period windows in stone or brick generally suit sand mastic and newer frames generally get a flexible sealant.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures.
Is it messy?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done and you will get one quote.

Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Do not paint over the new mastic
- Inspect the joints round the windows every year or so
- Make sure water runs off the sill
- Ask the planning authority about consent for listed or conservation-area homes
When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.
DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not 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.
When to call us in Painters Ash
Timber swells and shrinks with the weather. The movement cracks the mastic over time.
Signs it’s time to call us include:
- A silicone bead on a sash window that spoils the look
- Mastic worn away on windows facing the weather
- Gaps round a timber door in stone or brick
- Patchy fillers round a sash window
Letting a property close to Ebbsfleet International station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about.

Surface by surface
Tenement and terrace windows
Rows of sash windows on tenements and terraces often need renewing together. We work on single windows or whole elevations.
Stone surrounds
Stone openings are rarely perfectly straight, so the gap isn’t the same all the way round. We shape it by hand to follow the stone.
