What the job involves on each surface
Period and listed homes
A traditional finish suits a period property, and sand mastic is one of them.
Tenement and terrace windows
Where a building is shared, window work may involve neighbours so it’s worth checking responsibilities.
How we handle sand mastic in Burchett's Green
On many period windows, sand mastic looks right and suits the building. Newer frames normally get a flexible sealant instead and we will explain which is best for yours. Typical jobs include failed mastic on an exposed elevation and modern sealant on a period surround, on period & listed homes, tenement windows and stone surrounds.
Mastic can only go onto a dry, clean joint, so window work in Burchett's Green is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
You get a one-year guarantee, the same in Burchett's Green as everywhere else we work.

How the visit works
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours for a single window, longer for several and we leave things clean and tidy. Somewhere as small as Burchett's Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we look at the surrounds with you and agree what needs doing.
- We rake out the old mastic and clean the joint.
- Deep voids are packed so the mastic is the right thickness.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Getting ready for the visit

What does sand mastic cost?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before any work starts.
Can you do several jobs on one visit?
Of course. Combining jobs makes good use of the visit.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status and we are fully insured too.
Should I use sand mastic or silicone?
Sand mastic generally suits period timber windows best. On modern frames, we’d normally use a flexible sealant.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
How long will you be here?
Typically it takes a few hours for a single window, longer for several. Bigger jobs take longer, and we’ll say how long yours will take.
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

Why it’s worth doing now in Burchett's Green
Not every draught comes from the sashes themselves. Gaps between the frame and the wall can be just as bad, and renewing the mastic closes them. Around Burchett's Green, 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. For a quick quote, please phone 0345 464 0079 or drop us an email and we will talk you through it.

What sand mastic looks like in Burchett's Green
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Harleyford Manor (about 2.1 miles north) nearby, there’s older building stock in the area around Burchett's Green 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.
Homes close to Saint John the Evangelist include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in. If you look after a building such as Burchetts Green CofE Infants' School, its window and door frames need their mastic kept sound, just like a home’s. For landlords with property near Furze Platt station, any sash windows need sound mastic to keep draughts and rain out.
