Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
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 does not work out, we can still put it right.
Sand mastic for homes and businesses in Mayes Green
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s a mix of sand and a linseed-oil-based binder and built up by hand. On period homes, it looks right where silicone wouldn’t. If you have weathered mastic on the most exposed windows and old sand mastic that has cracked, crumbled or fallen out, we can put it right, on period & listed homes, tenement windows and brick reveals alike.
Mastic can only go onto a dry, clean joint, so window work in Mayes Green is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
You get a 12-month guarantee, the same in Mayes Green as everywhere else we work.

Surface by surface
Timber door frames
Door frames get knocked and soaked and the mastic can crack early. It’s renewed by hand.
Period and listed homes
Many older homes were built with sand mastic round the windows. On listed buildings, check with your planning authority first.
Looking after it afterwards
Aftercare is simple:
- Find out about consent before window work on a listed home
- Ask us before painting near the mastic
- Ask a joiner to look at soft timber first
- Do not run silicone over sand mastic
Look at the mastic when you look over the windows. Catching cracks early keeps repairs small.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber, which can lead to rot.
How we quote for sand mastic
The price is agreed before any work begins. It’s based on:
- How many areas need sealing
- Any mould that needs treating

- Working hours on commercial sites
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and give you a clear quote before any work starts.
What to tell us for a quote
You do not need to know the technical terms. Just tell us:
- Whether it has been sealed before
- If it’s domestic, commercial or a hotel

Getting a quote is simple: let us know what needs doing and where and its rough size. Photos by email help us understand the job, and we’ll come back to you with a quote.

What we’re called out for in Mayes Green
Previous repairs in cement or silicone often trap water or crack away. They do not move with the timber, and they generally need raking out.
Look out for any of the following:
- Weathered mastic on the most exposed windows
- Window mastic to renew ahead of painting
- Silicone on a period window that looks wrong
- Old sand mastic that has cracked, crumbled or fallen out
If you live in an older home near Church of St John the Baptist, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

The process
You don’t need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the job takes a few hours for a single window, longer for several in most cases. Somewhere as small as Mayes Green, 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.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Mention any sign-in or site rules at work premises
- Clear items away from the joints we’re working on
