Sand Mastic in Bassett Green
Problem with your window and door surrounds in Bassett Green? We cut out the old, prepare the joints and apply the right sealant.
- Mastic dropping out of the joint
- Tired mastic found when preparing windows for paint
- Failed mastic on an exposed elevation
Sand mastic in Bassett Green, done properly
A silicone bead around a sash window can look out of place and isn’t always the right material. Sand mastic is the traditional choice, and we can replace one with the other. If you are dealing with open joints round the window box and mastic round period door frames that has failed, we can put it right, whatever the surface.
Homes around Bassett Green 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.
Your job is guaranteed for a year, as with all our work.

How to look after the new joints
Aftercare is simple:
- Keep modern sealant off the mastic
- Take care around the mastic when scraping paint
- Ask us before painting near the mastic
- Look over the window mastic once a year
Make sure water drains away from the window surround. Constant wetting wears the mastic faster.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber and timber that stays wet can rot.
Frames and glazing around Bassett Green
Bassett Green is within about 3 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you live in an older home near St Alban's Church, the joint between an old wall and a newer frame is normally the first place rain gets in. Schools such as Bassett Green Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

Bassett Green questions
Does living near the coast affect sand mastic in Bassett Green?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Can you help a landlord with a rental near Swaythling station?
Yes, we work for letting agents and landlords. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before work begins.
Can new sealant go over the old?
No, it will not last. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Should I check with the council before work on a listed or conservation-area home?
Yes, it’s worth checking. Ask your local planning authority whether consent is needed for listed or conservation-area properties.
Can sand mastic be painted?
The usual advice is to leave sand mastic unpainted. Ask us before you decorate around it and we’ll advise.
Do you hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
What does sand mastic cost?
Size, access and the old material all affect the cost. Call for a quick quote and we will talk you through it.
Do you take out the old sealant first?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Leave it or put it right?
Draughts round a sash window are not always the sashes. Open mastic joints round the box can let air in and new mastic seals them. In an older home around Bassett Green, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
What you pay reflects the work, not guesswork. That’s why we ask about the job first and agree the price before starting.
