Sand mastic for homes and businesses in Locksgreen
For a listed home or one in a conservation area, ask your local planning authority if consent is needed before window work. Like-for-like sand mastic is often the preferred finish. If you have gaps between timber frames and stone or brick and draughty sash windows at the surround, we can put it right.
Somewhere as small as Locksgreen, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
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
You will get a clear quote before any work starts. It’s based on:
- Whether there’s mould to deal with
- How many rooms, windows or areas are involved
- Whether the work is at height
- Working hours on commercial sites
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, ring 0345 464 0079 or send us an email for an honest opinion and a quote.
Helping us quote
Photos help, but a description is a good start. Please mention:
- How we’d reach the joints
- Roughly how big the job is
- If it’s domestic, commercial or a hotel
- Photos by email, if that is easy
There’s no standard price list, as no two jobs are quite the same. Instead, we send you a clear quote for your job. To arrange one, call 0345 464 0079 or drop us an email.

What sand mastic looks like in Locksgreen
Locksgreen is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Historic houses like Swainston Manor (about 1.7 miles south) are a reminder that the area around Locksgreen has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
In and around Locksgreen, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

How the visit works
Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take anything from a few hours to a full day, depending on how many windows. Somewhere as small as Locksgreen, 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.
- 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
- Mention if the joints have been sealed before
- Mention any leaks or damp you’ve noticed
- Mention any tricky access

Related advice
Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Ask us before painting near the mastic
- Do not run silicone over sand mastic
- Check the mastic when you check the paintwork
- Ask a joiner to look at soft timber first
Leave the new mastic unpainted, as traditional guidance advises. If you are redecorating, ask us first.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Locksgreen questions
Does the coastal weather in Locksgreen affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Can you do sand mastic in Locksgreen?
Yes, Locksgreen is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or email us with a few details of the job, and we will send you a clear quote.
Is consent needed for window work on a listed home?
Yes, it’s worth checking. Your local planning authority can say if consent is needed for listed or conservation-area properties.
Do you have insurance?
Yes. We’re fully insured.
Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.
Do you guarantee sand mastic work?
There’s a 12-month guarantee on every job.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.

What we are called out for in Locksgreen
Scraping and sanding before painting can loosen old mastic. It’s often found when windows are being prepared for paint, which is a good time to renew it.
Signs it’s time to call us include:
- Draughty sash windows at the surround
- Old cement repairs round a window that have failed
- Gaps where the frame meets the masonry
- Old sand mastic that has cracked, crumbled or fallen out
Historic houses such as Swainston Manor, about 1.7 miles south, show how far back building around Locksgreen goes.
