Sand mastic for homes and businesses in Leigh Park
If your home is listed or in a conservation area, check with your local planning authority whether consent is needed for work to windows. Like-for-like sand mastic is often the preferred finish. We work on brick reveals, stone surrounds and sash and case windows, and people most often call us about tired mastic found when preparing windows for paint and patchy fillers round a sash window.
Houses in smaller places like Leigh Park can stand more in the open than those in a built-up town. That’s hard on the mastic around frames and sills.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Surface by surface
Tenement and terrace windows
Tenements and terraces often have many sash windows with ageing mastic. We work on single windows or whole elevations.
Timber door frames
Period doors in stone or brick openings are often pointed with sand mastic. The method is the same as for windows.
Should I try it myself first?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Leigh Park: your questions answered
Do you cover smaller places like Leigh Park?
Yes. Leigh Park is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Does living near the coast affect sand mastic in Leigh Park?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Should I use sand mastic or silicone?
Sand mastic usually suits period timber windows best. Modern frames normally suit a flexible sealant.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Can tenants book the work?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done and you will get one quote.
What sealant do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we’re using.
Honest limits
To be straight with you, there are a few things sealant won’t fix:
- Planning or listed building consent (your local planning authority decides)
- Damaged stone surrounds
- Broken panes

Why it’s worth doing now in Leigh Park
Replacing sash windows is a big decision for a period home, and in listed buildings it may need consent. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Homes in smaller places like Leigh Park can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.

How it works
We keep the work tidy and contained to the area we’re working on, so you can carry on as normal. Expect the work to take a few hours per window, depending on the condition of the joints, and we tell you how long to leave it before we go. For a job in Leigh Park, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We start by checking each surround and agreeing the joints to renew.
- The loose and crumbling mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The mastic is finished to sit tidily against the stone or brick.
Before we arrive
- Try not to wet indoor joints just before the visit
- Let us know if you’ve seen damp or leaks
- Mention if the joints have been sealed before

Leigh Park homes and the weather
Leigh Park 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. That is hard on the mastic around older windows and doors, especially on the side facing the sea. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you look after a building such as Riders Infant School, the mastic around its windows and doors needs looking after like any other building’s. Letting a property close to Havant station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about. In the older streets around St Francis, the joint between an old wall and a newer frame is generally the first place rain gets in.
Leigh Park is about 1 mile north of Havant, in Hampshire. For sand mastic in and around Leigh Park, it’s easy to get a quote: please call 0345 464 0079 or email us.

Aftercare tips
How long the joints last depends on use and care. We suggest:
- Take care around the mastic when scraping paint
- Find out about consent before window work on a listed home
- Leave the new mastic unpainted
- Inspect the joints round the windows every year or so
Avoid painting over the new mastic, which is the traditional advice. Ask us before any decorating around it.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber and timber that stays wet can rot.
