Sand mastic in Slough
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant and we will explain which is best for yours. If you have silicone on a period window that looks wrong and draughts and rain around sash boxes, we can put it right.
Town-centre flats, shops and offices in Slough have long runs of frames and glazing, often on upper floors. A cracked joint on an upper floor can let water in long before anyone spots it.
You are covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

Why it’s worth doing now in Slough
Gaps round a sash window let in rain and draughts. Left, water can reach the timber and the wall so renewing it early protects the window. In flats, shops and offices in Slough, a failed joint can let water into the unit below or behind a wall, where it can go unnoticed until the damage is done.

Is there any odour?
Some sealants have a smell while they cure. Ventilation helps.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
How much does sand mastic cost in Slough?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
When will the new mastic be hard?
A skin forms quite soon, but full hardening takes longer. We will explain what to expect before we leave.
Is consent needed for window work on a listed home?
It’s best to ask your local planning authority first. Sand mastic is often favoured as like for like, but they decide.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.

Sand mastic in Slough: local notes
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. With historic houses such as Windsor Castle (about 2.1 miles south) nearby, there’s older building stock in the area around Slough as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
In the older streets around St Michael and All Angels, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For landlords with property near Slough station, older sash windows in a rental need their mastic kept sound to keep the weather out. If you look after a building such as Herschel Grammar School, the mastic around its windows and doors needs looking after like any other building’s.

DIY sealant or a professional job?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
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.
