Sand mastic for sash & case windows in Scarborough, Medway
We cover Scarborough for traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old material cut out, joints cleaned and sealed neatly and a one-year guarantee.
- Gaps round a timber door in stone or brick
- Draughts and rain around sash boxes
- Open joints round the window box
Can I do it myself?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you’re 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.
Sand mastic in Scarborough, done properly
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant and we will explain which is best for yours. We work on sash and case windows, brick reveals and stone surrounds, and people most often call us about patchy fillers round a sash window and mastic round period door frames that has failed.
Homes in small places like Scarborough often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Scarborough: your questions answered
Can you help a landlord with a rental near Snodland station?
Yes, we work for landlords and agents. You can call 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Do you cover smaller places like Scarborough?
Yes, we do. 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.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
What exactly 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.
How do I get a quote for sand mastic in Scarborough?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before any work starts.
Do I need to be at home?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Are you an approved applicator?
Yes. We are approved under the ARBOMaster scheme.
Do you remove the old sealant?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Scarborough homes and the weather
Historic houses like Starkey Castle (about 1.7 miles north) are a reminder that the area around Scarborough 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 Burham Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages. Homes close to St Mary's Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Letting a property close to Snodland station? Then older sash windows in a rental need their mastic kept sound to keep the weather out.

How it works
We keep the work tidy and contained to the area we’re working on, so you can carry on as normal. Expect the work to take a few hours per window, depending on the condition of the joints. For a village or hamlet like Scarborough, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- Large voids are packed out first, so the mastic is not too thick.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The mastic is finished to sit tidily against the stone or brick.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Keep children and pets away from the work area
- Tell us about any water getting in

Advice
Different surfaces, different methods
Tenement and terrace windows
Windows above ground floor need the right access. Let us know the floor and we’ll confirm access.
Period and listed homes
Period homes look their best with traditional materials.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Ask the planning authority about consent for listed or conservation-area homes
- Avoid patching sand mastic with silicone
- Keep sills and gutters clear so water drains away
- Plan mastic work ahead of painting
Leave the new mastic alone while it firms up. It skins over quickly, but takes longer to harden fully.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber and timber that stays wet can rot.
