Sand mastic for homes and businesses in Burnt Hill
If your home is listed or in a conservation area, check with your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. If you have patchy fillers round a sash window and mastic worn away on windows facing the weather, we can put it right, on brick reveals, stone surrounds and tenement windows alike.
In a village or hamlet like Burnt Hill, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
We stand behind the work with a 12-month guarantee, so you’re not left on your own once the job is done.

Looking after it afterwards
A little care helps the new joints last. Our advice:
- Inspect the joints round the windows every year or so
- Get any rot dealt with first
- Ask the planning authority about consent for listed or conservation-area homes
- Keep modern sealant off the mastic
Avoid painting over the new mastic, as traditional guidance advises. Ask us before any decorating around it.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber, which can lead to rot.
FAQs for Burnt Hill
Can you do sand mastic in Burnt Hill?
Yes. Our work covers London and the South East, and Burnt Hill is part of that. You can ring 0345 464 0079 or email us and let us know what needs doing, and we’ll send you a clear quote.
Do you cover smaller places like Burnt Hill?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
What sealant do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Can old silicone round a sash window be swapped for sand mastic?
Yes, it’s a common request. All the old silicone is removed first so the mastic can sit properly.
How long does sand mastic take to harden?
It takes a while. The skin forms first, and the full set comes later, and we’ll tell you what to expect.
Can I choose the sealant colour?
Yes. White, clear and grey are common, and other colours are available for many products, and we’ll agree it with you first.
What information do you need?
The location, the problem and the rough size of the job. Photos by email help too.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
What we’re called out for in Burnt Hill
Most of it is simply age. Sand mastic is a maintenance item like any pointing and how long it lasts depends on the weather it faces.
These are the problems we are asked about most:
- Open joints round the window box
- Wind and rain getting in round a sash window
- Tired mastic found when preparing windows for paint
- Old sand mastic that has cracked, crumbled or fallen out
Managing a site like Yattendon C.E. Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.
What your quote should include
- How hidden problems are handled
- Is VAT in the price?
- Whether you can choose the colour
- How long to leave it before use
Quotes for sand mastic in Burnt Hill
We don’t publish a price list, because no two jobs are the same. What we look at:
- The product the joint needs
- The number and length of the joints
- How many areas need sealing
- Working hours on commercial sites
Doing several joints on one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. We’ll give you a clear quote for the lot.

What to tell us when you ask for a quote:
- Pictures of the joints, sent by email
- Whether it’s a home or a business

Call for a quick quote, or send an email if you’d rather. Tell us about the joints that need doing and we’ll explain what’s involved before giving you a price.
What we do, step by step
Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a few hours per window, depending on the condition of the joints. Somewhere as small as Burnt Hill, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
How to prepare
- Let us know if you’ve seen damp or leaks
- Clear items away from the joints we are working on
- For business premises, tell us about site rules or sign-in

Windows and doors in Burnt Hill
Rainfall in the South East is lower than in much 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 Basildon Park (about 3.5 miles north-east) nearby, there’s older building stock in the area around Burnt Hill as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you let a flat or house near Pangbourne station, any sash windows need sound mastic to keep draughts and rain out. For an older house near a landmark such as Church of St Peter and St Paul, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
