About our sand mastic in Hare Green
On many period windows, sand mastic looks right and suits the building. On modern frames we’d normally use a flexible sealant and we’ll explain which is best for yours. We work on brick reveals, tenement windows and stone surrounds, and people most often call us about crumbling sand mastic round a window and silicone on a period window that looks wrong.
In a village or hamlet like Hare Green, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
Our work is backed for twelve months, in Hare Green and everywhere else we cover.

When to call us in Hare Green
Most of it is simply age. Even well-laid mastic needs renewing in time, depending on exposure and upkeep.
Keep an eye out for these signs:
- Modern sealant on a period surround
- Mastic dropping out of the joint
- Mastic worn away on windows facing the weather
- Old cement repairs round a window that have failed
Rented homes near Great Bentley station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.

Windows and doors in Hare 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. Historic houses like Castle House (about 5 miles north) are a reminder that the area around Hare Green has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
If you look after a building such as St George's Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s. Homes close to Church of St George include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Advice

Also in Hare Green
Why it’s worth doing now in Hare Green
Not every filler suits an old window surround. Sand mastic matches what was there, which can matter on listed and conservation-area homes. Older cottages and farmhouses around Hare Green can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Doing several joints on one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

Keeping the joints in good condition
Aftercare is simple:
- Clear gutters so water does not pour onto the windows
- Keep modern sealant off the mastic
- Avoid heavy scraping on the mastic joint
- Ask a joiner to look at soft timber first
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber, which can lead to rot.
How the job changes by surface

Questions from Hare Green
Do you cover Hare Green for sand mastic?
Yes. Our work covers London and the South East, and Hare Green is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job.
Will you come out to Hare Green?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
What guarantee comes with the work?
You get our one-year guarantee to all our work.
Where are you based?
We are a Crawley-based firm. We work across South East England, London and Scotland.
Is it OK to seal over old sealant?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Do you work for letting agents?
Yes. We work in homes, commercial premises and hotels.
Do you offer different sealant colours?
We’ll suggest a colour to suit the surroundings, from white and clear to greys and other shades. The product needed can limit the range.
Honest limits
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Putty and glazing repairs
- Crumbling stone or brickwork round the window
- Decayed frames that need repair
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think.
