Sand Mastic in Thorpe Bay
Problem with your window and door surrounds in Thorpe Bay? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Weathered mastic on the most exposed windows
- Modern sealant on a period surround
- Gaps round a timber door in stone or brick
Should I try it myself first?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Sand mastic for homes and businesses in Thorpe Bay
Fresh sand mastic forms a skin quite soon but full hardening takes longer. Traditional guidance is not to paint over it and we will advise if you’re redecorating. We work on period & listed homes, tenement windows and stone surrounds, and common reasons people get in touch are old sand mastic that has cracked, crumbled or fallen out and cracked mastic round a front door frame.
Many houses in smaller places like Thorpe Bay have conservatories, garden rooms or patio doors. Those joints need the same attention as the main windows, and any older timber or sash windows need a sealant that suits them.
There’s a 12-month guarantee on every job.

In total, it normally takes a few hours per window, depending on the condition of the joints.

- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.

Thorpe Bay homes and the weather
Thorpe Bay is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Homes close to St Augustine include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For site and facilities teams at buildings such as Thorpedene Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

Common questions in Thorpe Bay
Do you cover smaller places like Thorpe Bay?
Yes, Thorpe Bay is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

What is sand mastic?
Sand plus a binder based on linseed oil. It’s built up in the joint by hand and finished to sit neatly against the masonry.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is normally more efficient.
Where do you work from?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Do I need permission for sand mastic on a listed building?
Yes, it’s worth checking. Your local planning authority can say if consent is needed for work on a listed home or in a conservation area.
Can you seal over the old sealant?
No, because it fails. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Are you fully insured?
Yes, we’re fully insured for every job we do.
What we cannot put right
New sealant can’t fix everything, and we’d rather say so up front. It won’t solve:
- Broken panes
- Rotten sashes, sills or window boxes (a joiner’s job)
- Masonry that needs repairing
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think before you book.
Surfaces we seal
- Timber door frames
- Period & listed homes
- Sash and case windows
- Brick reveals
- Tenement windows
- Stone surrounds
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Ask us before painting near the mastic
- Go gently near the mastic when preparing windows
- Plan mastic work ahead of painting
- Make sure water runs off the sill
Don’t run silicone over the new mastic. If anything cracks, get it looked at rather than patching it.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.
When to call us in Thorpe Bay
Water gets into small cracks in the mastic and loosens it further. Windows facing the weather tend to go first.
The problems people generally mention when they call include:
- Open joints round the window box
- Mastic that needs renewing before redecorating
- Mastic worn away on windows facing the weather
- Draughty sash windows at the surround
For landlords with property near Thorpe Bay station, any sash windows need sound mastic to keep draughts and rain out.
