Sand mastic for homes and businesses in Temple Mills
Sand mastic skins over fairly quickly but full hardening takes longer. Traditional guidance is not to paint over it and we’ll advise if you’re redecorating. We are often asked to deal with mastic dropping out of the joint and weathered mastic on the most exposed windows, on tenement windows, brick reveals and timber door frames.
From mansion-block windows to modern glazing in new flats, London has every kind of frame. Over the years, the sealant around them shrinks, cracks and pulls away, letting in draughts and water.
Big or small, it’s backed by our 12-month guarantee.

How it works
There isn’t much for you to do on the day. Point us to the joints and we will get on with it. The work itself takes anything from a few hours to a full day, depending on how many windows from start to finish. In Temple Mills, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- First, we look at the surrounds with you and agree what needs doing.
- Old, loose mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- We dress the surface so it sits neatly against the masonry.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- Mention any parking rules near the property
- Keep pets and children clear of the area while we work

Related advice
Do you need sand mastic in Temple Mills?
Scraping and sanding before painting can loosen old mastic. It’s often found when windows are being prepared for paint, which is a good time to renew it.
Signs it’s time to call us include:
- Crumbling sand mastic round a window
- Draughts and rain around sash boxes
- Mastic round period door frames that has failed
- Modern sealant on a period surround
As a London address, Temple Mills can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.
What your quote should include
- What happens if the job turns out different
- Is VAT in the price?
- Who turns up on the day
- How the colour is chosen
When it is not the sealant
We will not take on work that won’t last, so these are the limits:
- Putty and glazing repairs
- Crumbling stone or brickwork round the window
- Sashes that need overhauling
If you are not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer before you book.
What we seal
- Brick reveals
- Period & listed homes
- Sash and case windows
- Tenement windows
- Stone surrounds
- Timber door frames
What happens if it’s left?
If you are redecorating, renew the mastic first. Paint over cracked mastic won’t stop the gaps and traditional guidance is to leave the new mastic unpainted. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler for homes in Temple Mills.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we’ll explain what it covers.

Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Get any rot dealt with first
- Keep sills and gutters clear so water drains away
- Go gently near the mastic when preparing windows
- Ask us before painting near the mastic
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.
What sand mastic looks like in Temple Mills
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Sutton House (about 1.6 miles west) nearby, there’s older building stock in the area around Temple Mills as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
For an older house near a landmark such as St Eleutherius, the joint between an old wall and a newer frame is usually the first place rain gets in. Managing a site like Chobham Academy? Then its window and door frames need their mastic kept sound, just like a home’s.
