About our sand mastic in Wexham Street
Sand mastic suits most period window surrounds. Newer frames usually get a flexible sealant instead, and we’ll talk through which suits your home. We work on stone surrounds, brick reveals and timber door frames, and people most often call us about mastic worn away on windows facing the weather and gaps round a timber door in stone or brick.
Outdoor sealant needs dry, clean surfaces, so work on frames around Wexham Street is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
All of our work is guaranteed for twelve months.

Windows and doors in Wexham Street
The South East is one of 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 Windsor Castle (about 4.3 miles south) nearby, there’s older building stock in the area around Wexham Street as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
If you look after a building such as Khalsa Secondary Academy, the mastic around its windows and doors needs looking after like any other building’s. Homes close to St Andrew's Church Centre include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can go on one quote.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Do you need sand mastic in Wexham Street?
Paint, silicone or cement used over old mastic causes problems. They don’t suit the joint, and they generally need raking out.
People generally contact us when they notice one of these:
- Failed mastic on an exposed elevation
- A silicone bead on a sash window that spoils the look
- Draughty sash windows at the surround
- Patchy fillers round a sash window
Letting a property close to Slough station? Then older sash windows in a rental need their mastic kept sound to keep the weather out.

How the visit works
We bring everything the job needs with us, so you do not need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. Most jobs take anything from a few hours to a full day, depending on how many windows. Somewhere as small as Wexham Street, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.

Related advice
Should I try it myself first?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
What the job involves on each surface
Brick reveals
We rake out the old mastic and pack deep voids before the new mastic goes in.
Period and listed homes
Many older homes were built with sand mastic round the windows. On listed buildings, check with your planning authority first.
How to look after the new joints
Looking after new joints is easy:
- Avoid heavy scraping on the mastic joint
- Look over the window mastic once a year
- Avoid patching sand mastic with silicone
- Have rotten timber repaired before new mastic goes in
Do not touch or press the mastic while it hardens. It forms a skin fairly soon, but takes longer to harden fully.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber, which can lead to rot.
Why deal with it now?
Not every draught comes from the sashes themselves. Open mastic joints round the box can let air in, and renewing the mastic closes them. Where a wall is exposed, as many are in small places like Wexham Street, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
