Sand mastic for homes and businesses in Hatchford
Sand mastic suits most period window surrounds. Newer frames usually get a flexible sealant instead, and we’ll talk through which suits your home. We are often asked to deal with mastic worn away on windows facing the weather and old cement repairs round a window that have failed, on brick reveals, timber door frames and period & listed homes.
Mastic can only go onto a dry, clean joint, so window work in Hatchford is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Whatever the size of the job, you get the same 12-month guarantee.

Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
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, then guaranteed for a year.
Why deal with it now?
Not every draught comes from the sashes themselves. Gaps between the frame and the wall can be just as bad and new mastic seals them. Around Hatchford, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

Sand mastic in Hatchford: local notes
With historic houses such as Byfleet Manor (about 2.1 miles north-west) nearby, there’s older building stock in the area around Hatchford 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. 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.
Letting a property close to Effingham Junction station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about. If you look after a building such as St Matthew's CofE Aided Infant School, the mastic around its windows and doors needs looking after like any other building’s.

What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
Is it possible to paint over sand mastic?
The usual advice is to leave sand mastic unpainted. Ask us before you decorate around it and we’ll advise.

Most of the time, yes. We will explain which colours are available and agree one before any work starts.

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Ask the planning authority about consent for listed or conservation-area homes
- Get any rot dealt with first
- Sort the mastic before the decorators arrive
- Don’t paint over the new mastic
Keep paint scrapers and sanders off the mastic when redecorating. It can be damaged by heavy scraping.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
