Sand mastic for homes and businesses in Langley Common
We renew sand mastic around sash windows and doors set in stone or brick. The old mastic is raked out, and new mastic is applied and shaped by hand. We work on brick reveals, timber door frames and stone surrounds, and people most often call us about crumbling sand mastic round a window and gaps between timber frames and stone or brick.
Mastic can only go onto a dry, clean joint, so window work in Langley Common is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
All our work is covered by a 12-month guarantee, wherever you are in Wokingham.

Sand mastic in Langley Common: local notes
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homes close to St Eligius include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Schools such as The Coombes Church of England Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Langley Common: your questions answered
Is Langley Common in your area for sand mastic?
Yes. Our work covers London and the South East, and Langley Common is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job.
Can you help a landlord with a rental near Wokingham station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Does someone need to be in?
It depends on the job. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
When will the new mastic be hard?
It skins over fairly quickly but takes longer to harden fully. We will tell you what to expect for your job.
How long will you be here?
That depends on how much there is to do, but as a guide it takes anything from a few hours to a full day, depending on how many windows. We will tell you when we quote.
Can you quote for more than one area?
Yes, and it often makes sense. Doing several areas at once is generally more efficient.
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.

Related advice
Why act early in Langley Common
Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic suits the building and finishes neatly against the masonry. In a small place like Langley Common, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, call 0345 464 0079 or drop us an email for an honest opinion and a quote.

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Ask us before painting near the mastic
- Sort the mastic before the decorators arrive
- Avoid patching sand mastic with silicone
- Go gently near the mastic when preparing windows
When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber, which can lead to rot.
Surface by surface
Brick reveals
An open joint at a brick reveal lets weather in. Renewing the mastic closes it.
Tenement and terrace windows
Where a building is shared, window work may involve neighbours so it’s worth checking responsibilities.
Landlord and commercial work in Langley Common
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
For anyone letting property in or around Langley Common, several properties can be quoted together. Send us the addresses and the work at each, and photos by email help.
What we are called out for in Langley Common
Timber frames move with the seasons. The movement cracks the mastic over time.
It’s worth asking for a quote if you see:
- Window mastic to renew ahead of painting
- Mastic worn away on windows facing the weather
- Gaps round a timber door in stone or brick
- A silicone bead on a sash window that spoils the look
If you let a flat or house near Wokingham station, older sash windows in a rental need their mastic kept sound to keep the weather out.
