About our sand mastic in Burntcommon
A silicone bead around a sash window can look out of place and isn’t always the right material. Sand mastic is the traditional choice and we can swap the silicone for it. Common call-outs are for silicone on a period window that looks wrong and patchy fillers round a sash window, on sash and case windows, brick reveals and tenement windows.
Outdoor sealant needs dry, clean surfaces, so work on frames around Burntcommon is planned for dry weather. Let us know about access to all the frames, upstairs ones included.

How the job changes by surface
Period and listed homes
Sand mastic is the like-for-like choice for many period homes. On listed buildings, check with your planning authority first.
Timber door frames
Round a period front door, sand mastic gives the right look.
Why deal with it now?
Replacing sash windows is a big decision for a period home, and in listed buildings it may need consent. Where the frames are in good order, new mastic seals the surround. In a small place like Burntcommon, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

- Failed mastic on an exposed elevation
- Gaps where the frame meets the masonry

For site and facilities teams at buildings such as Send CofE Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Burntcommon homes and the weather
With historic houses such as Clandon Park (about 2.4 miles south) nearby, there’s older building stock in the area around Burntcommon as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s 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.
Rented homes near Clandon station change hands often, and any sash windows need sound mastic to keep draughts and rain out. Homes close to St William of York include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Is Burntcommon within the area you cover?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Is sand mastic better than silicone for my windows?
That depends on your windows. On many period windows, sand mastic looks right and suits the building, while modern frames normally get a flexible sealant.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
What is sand mastic?
A traditional pointing material made from sand and a linseed-oil-based binder for the joint between timber frames and masonry.
Do you guarantee sand mastic work?
Our 12-month guarantee applies to all our work.
Which products do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
