- Tired mastic found when preparing windows for paint
Surface by surface
Timber door frames
Sand mastic is used round timber door frames too. The method is the same as for windows.
Stone surrounds
Old stone surrounds are often uneven, so the gap is not the same all the way round. We shape it by hand to follow the stone.
Sand mastic in College Town, done properly
On many period windows, sand mastic looks right and suits the building. On modern frames we’d normally use a flexible sealant, and we will talk through which suits your home. We’re often asked to deal with failed mastic on an exposed elevation and tired mastic found when preparing windows for paint, across sash and case windows, stone surrounds and period & listed homes.
Homes around College Town range from older properties to newer houses, and their windows range just as widely. The right sealant depends on the frame and on what it sits in.
Each job carries a 12-month guarantee, large or small.

College Town homes and the weather
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Letting a property close to Blackwater station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about. In the older streets around Royal Memorial Chapel, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Schools such as College Town Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
College Town is about 1 mile south-east of Sandhurst, in Bracknell Forest. Jobs in College Town get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee. Across Bracknell Forest, we cover 41 places, College Town among them. Reading is on our list too, about 11 miles from College Town.

Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Ask us before painting near the mastic
- Ask a joiner to look at soft timber first
- Inspect the joints round the windows every year or so
- Ask the planning authority about consent for listed or conservation-area homes
Make sure water drains away from the window surround. Constant wetting wears the mastic faster.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens.
Why it’s worth doing now in College Town
Before painting the windows, it pays to renew the mastic. Paint over cracked mastic won’t stop the gaps and traditional guidance is to leave the new mastic unpainted. Homes in smaller places like College Town can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.

What else we do in College Town
How the visit works
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. Most jobs take a few hours per window, depending on the condition of the joints. A visit to College Town is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic is not too thick.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
Preparing for the visit
- Move anything stored near the joints
- Keep pets and children clear of the area while we work
- Mention any sign-in or site rules at work premises
