Sand mastic for homes and businesses in Pirbright
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s made from sand and a linseed-oil-based binder, applied by hand. On older homes, it suits the building far better than silicone. If you’re dealing with crumbling sand mastic round a window and weathered mastic on the most exposed windows, we can put it right, on brick reveals, sash and case windows and tenement windows alike.
Mastic can only go onto a dry, clean joint, so window work in Pirbright is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
Whatever the size of the job, you get the same one-year guarantee.

Do you cover Pirbright for sand mastic?
Yes. Our work covers London and the South East, and Pirbright is part of that. Just ring 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear quote.
Do you do commercial work?
Yes, regularly. We can plan bigger jobs in stages.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned.
What do you put in the joint?
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 tell you what we are using.
How long does sand mastic take to go off?
The surface skins quite quickly and it hardens fully over a longer time. The weather and joint depth both affect it.
Should I try DIY first?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
What affects the quote in Pirbright
Call for a quick quote. The main things that affect it are:
- Whether the work is at height
- The number and length of the joints
- Whether old sealant or filler has to be cut out
- Mould in or behind the old joints
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Asking for a quote
There’s no need for technical detail. It helps if you can tell us:
- How we’d reach the joints
- Photos by email, if that’s easy
- The type of property
- Where the property is
There’s no standard price list, because every job is different. Instead, your job gets its own clear quote. To get started, ring 0345 464 0079 or email us.
Why act early in Pirbright
Cement-based fillers and modern sealants don’t always suit a period surround. Sand mastic is the like-for-like choice and that can be important for listed homes. Where a wall is exposed, as many are in small places like Pirbright, 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 the cost depends so much on the job itself. Call for a quick quote.

What we are called out for in Pirbright
Most of it is simply age. Sand mastic is a maintenance item like any pointing, depending on exposure and upkeep.
Signs it’s time to call us include:
- Modern sealant on a period surround
- Patchy fillers round a sash window
- Tired mastic found when preparing windows for paint
- Failed mastic on an exposed elevation
For site and facilities teams at buildings such as Knowl Hill School, larger buildings have plenty of frames, and the mastic around each one ages.

What sand mastic looks like in Pirbright
With historic houses such as Wanborough Manor (about 4.4 miles south) nearby, there’s older building stock in the area around Pirbright 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’s traditional sand mastic. 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.
If you let a flat or house near Brookwood station, cracked sand mastic around sash windows lets in the draughts tenants complain about. In the older streets around Church of St Michael and All Angels, the joint between an old wall and a newer frame is normally the first place rain gets in.

Should I try it myself first?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
