Sand mastic for homes and businesses in Out Elmstead
We renew sand mastic around sash windows and doors set in stone or brick. Out comes the old, loose mastic, and new mastic is applied and shaped by hand. Typical jobs include failed mastic on an exposed elevation and mastic dropping out of the joint, across tenement windows, brick reveals and period & listed homes.
Somewhere as small as Out Elmstead, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
You get a one-year guarantee, the same in Out Elmstead as everywhere else we work.

Landlords, agents and businesses in Out Elmstead
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Why it’s worth doing now in Out Elmstead
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. Older cottages and farmhouses around Out Elmstead can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we will explain what it covers.

Questions from Out Elmstead
Do you work for landlords with property near Aylesham station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before any work starts.
Will you come out to Out Elmstead?
Yes, Out Elmstead is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you match the sealant colour?
Yes. Sealants come in white, clear, grey and other colours for many products, and we’ll agree it with you first.
Do you have insurance?
Yes. We’re fully insured, and we’ve been doing sealant work for more than 20 years.
Which is right for my windows, sand mastic or modern sealant?
We will help you decide. Sand mastic suits many period homes and newer frames suit modern sealant.
Will there be a smell?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Can you quote for more than one area?
Of course. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
Should I check with the council before work on a listed or conservation-area home?
Speak to your local planning authority before work starts. Sand mastic is often favoured as like for like but the decision is theirs.
When to call us in Out Elmstead
Age is the main cause. Even well-laid mastic needs renewing in time, depending on exposure and upkeep.
Signs it’s time to call us include:
- Gaps where the frame meets the masonry
- Mastic round period door frames that has failed
- Draughty sash windows at the surround
- Silicone on a period window that looks wrong
For an older house near a landmark such as Church of St Giles, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Inspect the joints round the windows every year or so
- Leave the new mastic unpainted
- Ask the planning authority about consent for listed or conservation-area homes
- Keep sills and gutters clear so water drains away
Leave the new mastic unpainted, which is the traditional advice. Ask us before any decorating around it.
Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger as more mastic falls out.
What sand mastic looks like in Out Elmstead
With historic houses such as Goodnestone Park (about 3.6 miles north-east) nearby, there’s older building stock in the area around Out Elmstead as well as newer homes. 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, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you look after a building such as Barham Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages. If you let a flat or house near Aylesham station, older sash windows in a rental need their mastic kept sound to keep the weather out.
