Sand mastic for homes and businesses in Bluetown
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s a mix of sand and a linseed-oil-based binder and built up by hand. On period homes, it looks right where silicone wouldn’t. Typical jobs include a silicone bead on a sash window that spoils the look and mastic that needs renewing before redecorating, across sash and case windows, stone surrounds and brick reveals.
Somewhere as small as Bluetown, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
The work is covered for a year after we finish. If anything isn’t right with it, call 0345 464 0079 or send us an email.

FAQs for Bluetown
Can you help a landlord with a rental near Sittingbourne station?
Yes. We work for landlords and letting agents as well as householders. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear quote.
Will you come out to Bluetown?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Where do you work from?
We work from Crawley. We cover Bluetown and the rest of Kent, along with the rest of our area.
What do you need from me for a quote?
The location, the problem and the rough size of the job. If you can, email a few photos.
Do you do commercial work?
Yes. We’ve worked for hotels, offices and other businesses.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Which is right for my windows, sand mastic or modern sealant?
We will talk it through with you. Period homes often look best with sand mastic, and modern sealants suit newer frames.
Is it possible to take out silicone and use sand mastic instead?
Yes. The silicone is cut out and the joint cleaned, then point it with sand mastic.
Why act early in Bluetown
Not every draught comes from the sashes themselves. Open mastic joints round the box can let air in and new mastic seals them. Older cottages and farmhouses around Bluetown can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.
Why us?
- Over 20 years’ experience
- Quality sealants from Arbo and Everbuild

What else we do in Bluetown
What happens on the day
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours per window, depending on the condition of the joints. In a small place like Bluetown, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic isn’t too thick.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- We dress the surface so it sits neatly against the masonry.
How to prepare
- Mention any sign-in or site rules at work premises
- Tell us about access, such as stairs, a lift or high-level joints
- Clear items away from the joints we’re working on

Advice
How the job changes by surface
Sash and case windows
The box of a sash and case window sits in the stone or brick opening. The gap round it is pointed with sand mastic.
Tenement and terrace windows
Where a building is shared, window work may involve neighbours so it’s worth checking responsibilities.
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Sand mastic in Bluetown: local notes
Historic houses like Belmont House and Gardens (about 4.4 miles east) are a reminder that the area around Bluetown has older buildings as well as new. 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, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For site and facilities teams at buildings such as Milstead and Frinsted Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s. If you let a flat or house near Sittingbourne station, cracked sand mastic around sash windows lets in the draughts tenants complain about. Homes close to Church of St Catherine include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.
