Sand mastic in Roke
On many period windows, sand mastic looks right and suits the building. Newer frames generally get a flexible sealant instead, and we will talk through which suits your home. We work on period & listed homes, timber door frames and sash and case windows, and the jobs we see most are tired mastic found when preparing windows for paint and weathered mastic on the most exposed windows.
Outdoor sealant needs dry, clean surfaces, so work on frames around Roke is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or email us.

Common questions in Roke
Is Roke within the area you cover?
Yes, Roke is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Is sand mastic in Roke guaranteed?
All our work, in Roke and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Do I have to be there?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Can I add another job to the visit?
Yes. Just list everything you need.
Can you seal over the old sealant?
No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.
Where are you based?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
Can old silicone round a sash window be swapped for sand mastic?
Yes. The silicone is cut out and the joint cleaned, then point it with sand mastic.
Is consent needed for window work on a listed home?
It’s best to ask your local planning authority first. Sand mastic is often favoured as like for like but the decision is theirs.

What sealant work cannot fix
A few problems are outside what sealant work can do:
- Timber that has rotted
- Whether work needs listed building consent
- Masonry that needs repairing
If in doubt, ring 0345 464 0079 or email us and we’ll say what we think before booking.
Surfaces we seal
- Sash and case windows
- Tenement windows
- Period & listed homes
- Timber door frames
- Brick reveals
- Stone surrounds
Why deal with it now?
Gaps round a sash window let in rain and draughts. Left, water can reach the timber and the wall so renewing it early protects the window. In a small place like Roke, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What it costs depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.

Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Go gently near the mastic when preparing windows
- Look over the window mastic once a year
- Sort the mastic before the decorators arrive
- Don’t paint over the new 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.
Do you need sand mastic in Roke?
Rain on the window surround works into any crack and loosens it further. Exposed elevations normally fail first.
It’s worth asking for a quote if you see:
- Mastic that needs renewing before redecorating
- Gaps between timber frames and stone or brick
- Wind and rain getting in round a sash window
- Weathered mastic on the most exposed windows
If you live in an older home near Church of St Helen, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Questions to ask before booking
- Which colour the sealant will be
- How the joint is cleaned and prepared
- Who does the work, and how experienced they are
- How hidden problems are handled
How the visit works
We bring everything the job needs with us. After a quick look at the joints together, we protect the area and start. It normally takes a few hours per window, depending on the condition of the joints. Somewhere as small as Roke, access is often the only tricky part. 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 is not too thick.
- The mastic is mixed, pressed into the joint by hand and shaped.
- We dress the surface so it sits neatly against the masonry.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Move anything stored near the joints
- Mention any leaks or damp you’ve noticed

Sand mastic in Roke: local notes
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Brightwell Manor (about 3.4 miles south-west) nearby, there’s older building stock in the area around Roke as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
For site and facilities teams at buildings such as Benson Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Should I try it myself first?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
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 does not work out, we can still put it right.
What the job involves on each surface
Sash and case windows
Most of our sand mastic work is on sash windows. Each joint round the box is raked out and renewed.
Stone surrounds
Stone openings are rarely perfectly straight, so the gap is not the same all the way round. We shape it by hand to follow the stone.
