Sand mastic for homes and businesses in Bedhampton
Fresh sand mastic forms a skin quite soon, but it takes longer to harden fully. Traditionally, sand mastic is left unpainted and we’ll advise if you are redecorating. If you’re dealing with draughts and rain around sash boxes and mastic worn away on windows facing the weather, we can help, whatever the surface.
Homes around Bedhampton 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.
You are covered for a year from the day we finish. If anything isn’t right with it, ring 0345 464 0079 or send us an email.

How the job changes by surface
Period and listed homes
Many older homes were built with sand mastic round the windows. On listed buildings, check with your planning authority first.
Stone surrounds
Stone surrounds suit sand mastic well. The finish blends with the masonry.
Windows and doors in Bedhampton
Bedhampton is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Historic houses like Warblington Castle (about 1.7 miles south-east) are a reminder that the area around Bedhampton has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
In the older streets around St Nicholas Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Letting a property close to Bedhampton station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about. For site and facilities teams at buildings such as Bidbury Junior School, its window and door frames need their mastic kept sound, just like a home’s.

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 job generally takes anything from a few hours to a full day, depending on how many windows. Parking around Bedhampton is usually easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- First, we look at the surrounds with you and agree what needs doing.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
Preparing for the visit
- Move anything stored near the joints
- Tell us if parking is tricky
- Let us know about earlier repairs to the joints

Related advice
Common questions in Bedhampton
Is sand mastic in a coastal place like Bedhampton any different?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Will you come out to Bedhampton?
Yes, Bedhampton is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can sand mastic be painted?
Traditional guidance is not to paint over sand mastic. Ask us before you decorate around it and we will advise.
What guarantee comes with the work?
You get our 12-month guarantee on every job.
Is sand mastic better than silicone for my windows?
We will help you decide. Sand mastic suits many period homes, and modern sealants suit newer frames.
Do I need permission for sand mastic on a listed building?
Checking first is sensible. Ask your local planning authority whether consent is needed for listed or conservation-area properties.
Can landlords and businesses book you?
Yes. Domestic, commercial and hotel work are all part of what we do.
What’s sand mastic made of?
It’s a mix of sand and a linseed-oil-based binder. It’s built up in the joint by hand and finished to sit neatly against the masonry.
Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Find out about consent before window work on a listed home
- Ask us before painting near the mastic
- Ask a joiner to look at soft timber first
- Clear gutters so water doesn’t pour onto the windows
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens as more mastic falls out.
Work for landlords, hotels and businesses
In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll quote.
When it is not the sealant
Some problems need a builder, plumber or other trade rather than us:
- Decisions on consent for listed homes
- Decayed frames that need repair
- Putty and glazing repairs
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.

Quotes for sand mastic in Bedhampton
For a quick quote, just ask. The main things that affect it are:
- Any working-time requirements on site
- How many areas need sealing
- The product the joint needs
- Whether the work is at height
What you pay reflects the work, not guesswork. That is why we ask about the job first and give you a clear price before any work starts.
Helping us quote
What to tell us when you ask for a quote:
- What’s wrong with the joints now
- The address or postcode of the job
- Access, such as stairs, a lift or height
- Any previous sealing or DIY work
If you are in Bedhampton and need sand mastic, phone 0345 464 0079 or drop us an email. A short description of the job and where it is helps us quote, and we’ll agree the price before any work begins.
Why deal with it now?
Filling over old, loose mastic does not last. Raking out and preparing the joint gives it a sound base so the new mastic stays put. In a smaller place like Bedhampton, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.
