Somewhere as small as Upper Chute, 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.
- We rake out the old mastic and clean the joint.
- Large voids are packed out.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
How to prepare

Sand mastic in Upper Chute
Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. We rake it out and renew it so the surround looks right again. We work on timber door frames, stone surrounds and period & listed homes, and the jobs we see most are mastic round period door frames that has failed and mastic dropping out of the joint.
Somewhere as small as Upper Chute, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
A one-year guarantee comes as standard, so you’re covered after we have gone.

What the job involves on each surface
Timber door frames
Sand mastic is used round timber door frames too. We renew it the same way as on windows.
Stone surrounds
Stone openings are rarely perfectly straight, so the joint varies in width. Sand mastic is shaped by hand to suit.
Looking after it afterwards
So the new joints stay in good condition:
- Go gently near the mastic when preparing windows
- Inspect the joints round the windows every year or so
- Ask us before painting near the mastic
- Clear gutters so water doesn’t pour onto the windows
Check the mastic when you check the paintwork. Catching cracks early keeps repairs small.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber and timber that stays wet can rot.

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.

Upper Chute questions
Will you come out to Upper Chute?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is Upper Chute in your area for sand mastic?
Yes. We work across London and the South East, and Upper Chute is part of that. Just phone 0345 464 0079 or email us with a few details of the job.
How long will you be here?
As a guide, most jobs take a few hours per window, depending on the condition of the joints. Larger jobs naturally take longer, and we’ll say how long yours will take.
Is consent needed for window work on a listed home?
Checking first is sensible. Your local planning authority can say if consent is needed for listed or conservation-area properties.
Do the sealants smell?
Possibly a little. It fades as the sealant cures, and ventilation helps.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is generally more efficient.
What should I tell you?
Let us know what needs doing and where. If we need more, we will ask.
Can you work on commercial sites?
Yes. We’ve worked for hotels, offices and other businesses, and we are fully insured.
What happens if it’s left?
Not every filler suits an old window surround. Sand mastic matches what was there and that can be important for listed homes. Where a wall is exposed, as many are in small places like Upper Chute, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

When to call us in Upper Chute
Age is the main cause. Even well-laid mastic needs renewing in time, depending on exposure and upkeep.
These are the problems we’re asked about most:
- Failed mastic on an exposed elevation
- Mastic that needs renewing before redecorating
- Wind and rain getting in round a sash window
- Crumbling sand mastic round a window
In the older streets around Church of St Nicholas, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
