Window mastic in Paley Street, done properly
The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. Our applicators cut it out and replace it with a flexible, weatherproof sealant. We’re often asked to deal with damp patches on the reveal after heavy rain and cold air getting in at the frame edge, on uPVC windows, composite doors and patio & French doors.
Around Paley Street, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
The work is covered for a year after we finish. If anything is not right with it, ring 0345 464 0079 or send us an email.

What happens if it’s left?
Working on frames from a ladder with a sealant gun isn’t easy, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, in a sealant suited to the wall. Where a wall is exposed, as many are in small places like Paley Street, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote.

What window mastic looks like in Paley Street
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Dorney Court (about 3.8 miles north-east) nearby, there’s older building stock in the area around Paley Street as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Rented homes near Maidenhead station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Historic houses such as Dorney Court, about 3.8 miles north-east, show how far back building around Paley Street goes, and older homes nearby need a sealant that suits their walls.

Common problems we fix in Paley Street
Plenty of failed mastic was poorly applied in the first place. Sealant run over dust, wet brick or loose mortar didn’t grip properly, and it lets go sooner than it should.
People normally contact us after spotting one of these:
- Draughts coming in around windows and doors
- Rain getting in at the frame or under the sill
- Cracked internal joints between frame and plaster
- Black, perished sealant on frames
For site and facilities teams at buildings such as Holyport College, larger buildings have plenty of frames, and the mastic around each one ages.

What the job involves on each surface
Timber windows & doors
Soft or rotten wood can’t be sealed successfully. We’ll point out any rot we find, as that is a job for a joiner.
Composite doors
A composite door normally sits in a plastic outer frame, so its perimeter joint is sealed much like a window. We match the colour to the frame.
For landlords and businesses
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will quote.
