Specialist sand mastic for Cade Street: careful preparation, the right product and tidy work. Call for a quick quote.
- Cracked mastic round a front door frame
- Draughty sash windows at the surround
- Weathered mastic on the most exposed windows
How the visit works
The work is kept neat and contained to the joints we are treating. The job generally takes anything from a few hours to a full day, depending on how many windows, and we tell you how long to leave it before we go. Somewhere as small as Cade Street, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check the window surrounds and agree which joints need renewing.
- 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.
How to prepare
- For business premises, tell us about site rules or sign-in
- Let us know about earlier repairs to the joints
- Clear items away from the joints we’re working on

Advice
About our sand mastic in Cade Street
Sand mastic doesn’t last for ever, leaving gaps round the window. Renewing it closes the gap so the surround looks right again. We work on timber door frames, period & listed homes and stone surrounds, and people most often call us about a silicone bead on a sash window that spoils the look and failed mastic on an exposed elevation.
Somewhere as small as Cade Street, 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.
Our work is backed for twelve months.

Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
For landlords and businesses
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
We also work for property managers and facilities teams. We can quote a run of properties together, and we are fully insured for the work.
Cade Street questions
Can you do sand mastic in Cade Street?
Yes. Our work covers London and the South East, and Cade Street is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we’ll send you a clear quote.
Will you come out to Cade Street?

Is the work guaranteed?

Do you have insurance?

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 work on a listed home or in a conservation area.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
Can tenants book the work?
Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.
Is it possible to take out silicone and use sand mastic instead?
In most cases. The silicone is cut out and the joint cleaned before the sand mastic goes in.
What sealant work can’t fix
Before booking, it’s worth knowing the limits:
- Sashes that rattle, stick or won’t open
- Decisions on consent for listed homes
- Rotten sashes, sills or window boxes (a joiner’s job)
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly before booking.

What sand mastic looks like in Cade Street
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. With historic houses such as Bateman's (about 4.7 miles east) nearby, there’s older building stock in the area around Cade Street as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Managing a site like Heathfield Community College? Then its window and door frames need their mastic kept sound, just like a home’s.

What happens if it’s left?
Not every draught comes from the sashes themselves. Gaps between the frame and the wall can be just as bad and new mastic seals them. In a small place like Cade Street, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.

When to call us in Cade Street
Over the years, sand mastic weathers. It hardens, cracks and starts to come away from the frame or the masonry.
These are the problems we’re asked about most:
- Cement or filler used on old window joints that has cracked
- Wind and rain getting in round a sash window
- Gaps where the frame meets the masonry
- Mastic round period door frames that has failed
For an older house near a landmark such as The Parish Church of All Saints, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
What your quote should include
- Which sealant they’ll use, and why
- What insurance they hold
- Who does the work, and how experienced they are
- Whether you can choose the colour
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Have rotten timber repaired before new mastic goes in
- Keep modern sealant off the mastic
- Check with your local planning authority if your home is listed
- Ask us before painting near the mastic
Do not run silicone over the new mastic. If anything cracks, get it looked at rather than patching it.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
