How we handle sand mastic in Bladon
Sand mastic suits most period window surrounds. Newer frames normally get a flexible sealant instead, and we’ll talk through which suits your home. We work on tenement windows, brick reveals and stone surrounds, and the jobs we see most are gaps round a timber door in stone or brick and cement or filler used on old window joints that has cracked.
Mastic can only go onto a dry, clean joint, so window work in Bladon is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
Every job is covered by our 12-month guarantee.

Common problems we fix in Bladon
Scraping and sanding before painting can loosen old mastic. It’s often found when windows are being prepared for paint, which is a good time to renew it.
If you can see any of these, it’s time to have the joints looked at:
- Draughts and rain around sash boxes
- Mastic round period door frames that has failed
- Cement or filler used on old window joints that has cracked
- Tired mastic found when preparing windows for paint
For site and facilities teams at buildings such as Bladon Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Do you cover smaller places like Bladon?

Which is right for my windows, sand mastic or modern sealant?
For period timber windows in stone or brick, sand mastic is often the better fit. On modern frames, we’d normally use a flexible sealant, and we’ll explain why.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we’re fully insured.
What guarantee comes with the work?

Can you match the sealant colour?
We’ll suggest a colour to suit the surroundings. The product needed can limit the range.
Can I paint the new mastic?
Traditional guidance is not to paint over sand mastic. Ask us before you decorate around it and we will advise.
Can you do several jobs on one visit?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Why deal with it now?
Draughts round a sash window aren’t always the sashes. Gaps between the frame and the wall can be just as bad and new mastic seals them. Older cottages and farmhouses around Bladon can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or email us and we’ll talk you through it.

What sand mastic looks like in Bladon
With historic houses such as Blenheim Palace (about 0.9 miles north-west) nearby, there’s older building stock in the area around Bladon 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. 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.
Homes close to St Martin's Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Rented homes near Hanborough station change hands often, and any sash windows need sound mastic to keep draughts and rain out.
