Windows and doors in Lambs Green
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.
Rented homes near Faygate station change hands often, and any sash windows need sound mastic to keep draughts and rain out. In the older streets around St Mary Magdalene church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

About our sand mastic in Lambs Green
Our applicators renew the sand mastic around sash and case windows and doors in stone and brick. The old mastic is raked out, and new mastic is applied and shaped by hand. Common call-outs are for open joints round the window box and mastic round period door frames that has failed, on brick reveals, sash and case windows and stone surrounds.
Mastic can only go onto a dry, clean joint, so window work in Lambs Green is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
Each job carries a 12-month guarantee, large or small.

Honest limits
Some problems need a builder, plumber or other trade rather than us:
- Decayed frames that need repair
- Decisions on consent for listed homes
- Sash cords, weights and draught-proofing of the sashes
If in doubt, ring 0345 464 0079 or email us and we will say what we think.
Surfaces we seal
- Period & listed homes
- Stone surrounds
- Sash and case windows
- Tenement windows
- Brick reveals
- Timber door frames
Common problems we fix in Lambs Green
Timber frames move with the seasons. That movement opens up the mastic joint little by little.
Look out for any of the following:
- Gaps round a timber door in stone or brick
- Modern sealant on a period surround
- Old cement repairs round a window that have failed
- Failed mastic on an exposed elevation
Schools such as Rusper Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.
Questions to ask before booking
- What product goes in the joint
- How long to leave it before use
- How the colour is chosen
- How hidden problems are handled
What we do, step by step
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours for a single window, longer for several. For a village or hamlet like Lambs Green, 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 start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- Deep voids are packed so the mastic is the right thickness.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The finish is dressed so it sits neatly against the stone or brick.
Preparing for the visit
- Keep children and pets away from the work area
- Tell us if parking is tricky
- Mention if the joints have been sealed before

Is it worth trying it myself?

Do you guarantee sand mastic work?
There’s a 12-month guarantee on every job.
What information do you need?
The location, the problem and the rough size of the job. Photos by email help too.
Do you remove the old sealant?
Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.
Can sand mastic be painted?
Traditional guidance is not to paint over sand mastic. Ask us before you decorate around it and we will talk you through it.
For landlords and businesses
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll quote.
Failed sealant is one of the commonest items on a check-out report. Several properties can go on one quote.
What happens if it’s left?
If you are redecorating, renew the mastic first. Painting over failed mastic doesn’t seal it and traditional guidance is to leave the new mastic unpainted. Around Lambs Green, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and send you a clear quote before work begins.
