Sand mastic for homes and businesses in Skinners 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 sash and case windows, stone surrounds and brick reveals, and common reasons people get in touch are old sand mastic that has cracked, crumbled or fallen out and gaps where the frame meets the masonry.
Homes in small places like Skinners Green often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or send us an email.

What affects the cost of sand mastic
There’s no set price list. The quote depends on:
- Which sealant suits the joint
- Any mould that needs treating
- How many rooms, windows or areas are involved
- How easy the joints are to reach
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
What to tell us for a quote
You don’t need to know the technical terms. Just tell us:
- Any previous sealing or DIY work
- The problem you’ve noticed
- Where the property is
- The type of property
Getting a quote is simple: let us know the job and the location and its rough size. A few pictures by email make the job easier to understand, and we’ll come back to you with a quote.
How to look after the new joints
To keep the joints looking good and working properly:
- Look over the window mastic once a year
- Ask the planning authority about consent for listed or conservation-area homes
- Plan mastic work ahead of painting
- Ask us before painting near the mastic
Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.

Skinners Green questions
Is Skinners Green within the area you cover?
Yes. Skinners Green is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.

Yes, Skinners Green is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or email us and tell us what needs doing, and we will give you a clear quote.
Do you work for landlords and businesses?
Yes, we do. We work in homes, commercial premises and hotels.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that generally means someone at home.
Is sand mastic better than silicone for my windows?
We’ll talk it through with you. Sand mastic suits many period homes, and modern sealants suit newer frames.
Will there be a smell?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
What guarantee comes with the work?
Our one-year guarantee covers every job, sand mastic included.
Should I try it myself first?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
The process
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours per window, depending on the condition of the joints. Somewhere like Skinners Green needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- 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
- Mention any leaks or damp you’ve noticed
- Mention any sign-in or site rules at work premises
- Try not to wet indoor joints just before the visit

What the job involves on each surface
Brick reveals
Sand mastic is also used where timber frames meet brick. It suits older brickwork.
Period and listed homes
Many older homes were built with sand mastic round the windows. If your home is listed, ask your local planning authority about consent.
Why deal with it now?
Filling over old, loose mastic does not last. Raking out and preparing the joint gives it a sound base so the new work lasts. Around Skinners Green, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we will explain what it covers.

Frames and glazing around Skinners 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 Benham Park (about 1.4 miles north) are a reminder that the area around Skinners Green has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Schools such as John Rankin Infant and Nursery School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. If you live in an older home near Parish Church of St Michael, the joint between an old wall and a newer frame is usually the first place rain gets in. For landlords with property near Newbury station, older sash windows in a rental need their mastic kept sound to keep the weather out.
