Sand mastic in Sedlescombe, done properly
Sand mastic does not last for ever and gaps open up round the frame. Renewing it closes the gap and tidies the surround. We work on stone surrounds, period & listed homes and timber door frames, and the jobs we see most are failed mastic on an exposed elevation and tired mastic found when preparing windows for paint.
Homes in small places like Sedlescombe often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
Each job carries a 12-month guarantee, large or small.

Landlord and commercial work in Sedlescombe
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
Leave it or put it right?
If you’re redecorating, renew the mastic first. Paint over cracked mastic will not stop the gaps and traditional guidance is to leave the new mastic unpainted. In a small place like Sedlescombe, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or send us an email.

DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
The process
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a single window, longer for several and we leave things clean and tidy. For a village or hamlet like Sedlescombe, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic isn’t too thick.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us if parking is tricky
- For business premises, tell us about site rules or sign-in

Advice
Common problems we fix in Sedlescombe
Rain on the window surround works into any crack and loosens it further. Exposed elevations normally fail first.
Most people get in touch after spotting something like this:
- Draughts and rain around sash boxes
- A silicone bead on a sash window that spoils the look
- Mastic dropping out of the joint
- Weathered mastic on the most exposed windows
Rented homes near Battle station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.

How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Look over the window mastic once a year
- Ask us before painting near the mastic
- Find out about consent before window work on a listed home
- Do not run silicone over sand mastic
Leave the new mastic unpainted, which is the traditional advice. Ask us before any decorating around it.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens as more mastic falls out.
Different surfaces, different methods
Stone surrounds
The stone is treated with care when the old mastic comes out.
Brick reveals
Gaps between frame and brick let in rain and draughts. Renewing the mastic closes it.

Will you leave a mess?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
Is it OK to seal over old sealant?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
Can I add another job to the visit?
Yes, we can. More than one area can go on one quote.
Should I check with the council before work on a listed or conservation-area home?
Your local planning authority is the one to ask. They’ll tell you if consent is needed.
Do the sealants smell?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
Are you insured?
Yes. We’re fully insured, and we can confirm the details when we quote.
Frames and glazing around Sedlescombe
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Durhamford Manor (about 0.7 miles north-west) are a reminder that the area around Sedlescombe has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
In the older streets around The Parish Church of St John the Baptist, the joint between an old wall and a newer frame is generally the first place rain gets in. Managing a site like Sedlescombe CofE Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.
