How we handle sand mastic in Bradville
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s a mix of sand and a linseed-oil-based binder, applied by hand. On older homes, it suits the building far better than silicone. Common call-outs are for crumbling sand mastic round a window and gaps round a timber door in stone or brick, across stone surrounds, timber door frames and tenement windows.
Homes around Bradville range from older properties to newer houses, and their windows range just as widely. Each frame material needs the right sealant against the right wall.

How it works
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. It usually takes a few hours for a single window, longer for several. For a job in Bradville, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.

Advice
Should I try it myself first?
If you do try it yourself, take your time over the 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.
When it isn’t the sealant
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Sashes that rattle, stick or won’t open
- Decisions on consent for listed homes
- Cracked or broken glass
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think.
What we seal
- Sash and case windows
- Tenement windows
- Stone surrounds
- Brick reveals
- Period & listed homes
- Timber door frames
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. Around Bradville, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Take care around the mastic when scraping paint
- Ask us before painting near the mastic
- Clear gutters so water doesn’t pour onto the windows
- Avoid patching sand mastic with silicone
Avoid painting over the new mastic, as traditional guidance advises. Ask us before any decorating around it.
An open joint round the box lets weather through. Left, the gap tends to get bigger.
Bradville homes and the weather
With historic houses such as Linford Manor (about 1.5 miles north-east) nearby, there’s older building stock in the area around Bradville as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Milton Keynes, which Bradville is part of, is one of England’s post-war new towns. Many homes date from the post-war decades, and many will have had their original windows replaced. The mastic around replacement frames ages too, and gaps at sills and frame heads are where water gets in.
Managing a site like Pepper Hill School? Then the mastic around its windows and doors needs looking after like any other building’s. Rented homes near Wolverton station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. For an older house near a landmark such as Christ Church, the joint between an old wall and a newer frame is usually the first place rain gets in.

Your questions about sand mastic in Bradville
Is it worth replacing old sealant in an older home in Bradville?
Usually, yes, if it’s cracked, shrunk, mouldy or coming away. The key is cutting all the old sealant out, as new sealant will not bond to it.
Can you help a landlord with a rental near Wolverton station?
Yes, we work for landlords and agents. Just call 0345 464 0079 or drop us an email and tell us about the property, and we will send you a clear quote.
What guarantee comes with the work?
There’s a 12-month guarantee on every job.
Which is right for my windows, sand mastic or modern sealant?
Sand mastic normally suits period timber windows best. On modern frames, we’d normally use a flexible sealant, and we’ll explain why.
What does sand mastic cost?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You will get a clear quote before any work starts.
Are you an approved applicator?
Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
What’s sand mastic made of?
It’s sand mixed with a linseed-oil-based binder for the joint between timber frames and masonry.
How long does sand mastic take to harden?
The surface skins quite quickly, then hardens over a longer period. The weather and joint depth both affect it.
