Sand mastic in Wexham Court, done properly
We renew sand mastic around sash windows and doors set in stone or brick. Out comes the old, loose mastic, and new mastic is applied and shaped by hand. We are often asked to deal with weathered mastic on the most exposed windows and draughty sash windows at the surround, on sash and case windows, brick reveals and period & listed homes.
In a village or hamlet like Wexham Court, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
Big or small, it’s backed by our one-year guarantee.

Surface by surface
Sash and case windows
Sash windows are where we do most sand mastic work. We renew the mastic round each box.
Period and listed homes
On a listed home or in a conservation area, the right material matters. Like-for-like sand mastic is normally favoured.
The process
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes anything from a few hours to a full day, depending on how many windows from start to finish. Somewhere as small as Wexham Court, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Mention any parking rules near the property
- Keep children and pets away from the work area

Quotes for sand mastic in Wexham Court
Jobs vary more than people expect. What affects the quote:
- Access and height
- Whether there’s mould to deal with
- How many areas need sealing
- The number and length of the joints
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Helping us quote
To help us quote quickly, let us know:
- Photos by email, if that is easy
- The rough size of the job
- What’s wrong with the joints now
- If it’s domestic, commercial or a hotel
We don’t publish a price list, because every job is different. Instead, we send you a clear quote for your job. To arrange one, ring 0345 464 0079 or email us.
Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, 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.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
FAQs for Wexham Court
Can you do sand mastic in Wexham Court?
Yes. Our work covers London and the South East, and Wexham Court is part of that. You can phone 0345 464 0079 or email us and tell us what needs doing, and we will give you a clear quote.
Do you cover smaller places like Wexham Court?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do I need permission for sand mastic on a listed building?
Check with your local planning authority. They decide whether consent is needed.
What information do you need?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Can you replace silicone on a period window with sand mastic?
Yes, it’s a common request. The old silicone has to come out completely so the mastic can sit properly.
Can tenants book the work?
We are happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.
Can landlords and businesses book you?
Yes, regularly. We can quote for several properties at once, and between tenancies is a good time for the work.
Is sand mastic better than silicone for my windows?
It depends on the window. Period windows in stone or brick usually suit sand mastic and newer frames normally get a flexible sealant.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Sort the mastic before the decorators arrive
- Take care around the mastic when scraping paint
- Get any rot dealt with first
- Leave the new mastic unpainted
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.
When to call us in Wexham Court
Paint, silicone or cement used over old mastic causes problems. They do not move with the timber, and they normally need raking out.
It’s worth asking for a quote if you see:
- Mastic worn away on windows facing the weather
- Crumbling sand mastic round a window
- Gaps where the frame meets the masonry
- Draughts and rain around sash boxes
Rented homes near Slough station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.

Sand mastic in Wexham Court: local notes
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Windsor Castle (about 3.4 miles south) nearby, there’s older building stock in the area around Wexham Court as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Managing a site like Wexham School? Then the mastic around its windows and doors needs looking after like any other building’s. Homes close to Parish Church of St Mary include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
