Sand Mastic in Saunderton Lee
Problem with your window and door surrounds in Saunderton Lee? We remove the old material, prepare the joints and seal them properly, with a one-year guarantee.
- A silicone bead on a sash window that spoils the look
- Draughts and rain around sash boxes
- Old cement repairs round a window that have failed
Keeping the joints in good condition
So the new joints stay in good condition:
- Ask a joiner to look at soft timber first
- Look over the window mastic once a year
- Ask us before painting near the mastic
- Make sure water runs off the sill
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
Sound mastic protects the frame. Failed mastic lets water reach the timber, which can lead to rot.
About our sand mastic in Saunderton Lee
Fresh sand mastic forms a skin quite soon, but it takes longer to harden fully. Traditional guidance is not to paint over it, so ask us before you decorate. We work on timber door frames, stone surrounds and sash and case windows, and common reasons people get in touch are gaps between timber frames and stone or brick and modern sealant on a period surround.
Somewhere as small as Saunderton Lee, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
The work is covered for a year after we finish. If anything is not right with it, ring 0345 464 0079 or email us.

Can I do it myself?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

Frames and glazing around Saunderton Lee
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like West Wycombe Park House (about 3.6 miles south) are a reminder that the area around Saunderton Lee has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Schools such as St John's Church of England Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. Homes close to Church of St John the Evangelist include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you let a flat or house near Saunderton station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

Why deal with it now?
Filling over old, loose mastic doesn’t last. Raking out and preparing the joint gives it a sound base so the new mastic stays put. Around Saunderton Lee, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

Questions from Saunderton Lee
Is Saunderton Lee within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is Saunderton Lee in your area for sand mastic?
Yes. Our work covers London and the South East, and Saunderton Lee is part of that. You can phone 0345 464 0079 or send us an email and tell us what needs doing.
Do you offer different sealant colours?
We help you choose a colour that suits. The product needed can limit the range.
Can old silicone round a sash window be swapped for sand mastic?
Normally, yes. Once the silicone is out and the joint prepared, sand mastic is applied by hand.
What’s sand mastic made of?
Sand mastic is a traditional material for pointing round windows and doors. It combines sand with a linseed-oil-based binder.
Can I do it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Is consent needed for window work on a listed home?
Check with your local planning authority. They decide whether consent is needed for work to your windows.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Surface by surface
Stone surrounds
We take care not to mark the stone when the old mastic comes out.
Tenement and terrace windows
In shared buildings, the windows may be part of a wider repair, so check who is responsible first.
