Sand mastic for homes and businesses in Bridge
Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. We rake it out and renew it so the surround looks right again. We work on sash and case windows, period & listed homes and tenement windows, and the jobs we see most are mastic that needs renewing before redecorating and mastic dropping out of the joint.
Around Bridge, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
Every job is covered by our one-year guarantee, wherever you are in Kent.

DIY versus a professional finish
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Frames and glazing around Bridge
With historic houses such as Goodnestone Park (about 4.4 miles east) nearby, there’s older building stock in the area around Bridge as well as newer homes. In older buildings, 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.
Rented homes near Bekesbourne station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about. If you look after a building such as Bridge and Patrixbourne Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s. For an older house near a landmark such as Church of St Peter, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

How the visit works
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes a few hours per window, depending on the condition of the joints, depending on the size of the job. Somewhere like Bridge needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The finish is dressed so it sits neatly against the stone or brick.

Advice
Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Inspect the joints round the windows every year or so
- Take care around the mastic when scraping paint
- Don’t paint over the new mastic
- Check with your local planning authority if your home is listed
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.

Other services in Bridge
Why act early in Bridge
Not every filler suits an old window surround. Sand mastic matches what was there and that can be important for listed homes. Older cottages and farmhouses around Bridge can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Doing several joints on one visit generally makes better use of the time than several visits. We will give you a clear price for the lot.

Common questions in Bridge
Can you do sand mastic in Bridge?
Yes. We work across London and the South East, and Bridge is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job.
Is Bridge within the area you cover?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
When will the new mastic be hard?
It takes a while. It skins first and hardens fully later and we will give you an idea for your job.
Do you remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
What exactly is sand mastic?
Sand mastic is a traditional material for pointing round windows and doors. It combines sand with a linseed-oil-based binder.
Do the sealants smell?
Possibly a little. It fades as the sealant cures.
Can new sealant go over the old?
No, because it fails. The old sealant always comes out first.
Are you an approved applicator?
Yes. We’re approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
