What is sand mastic?
A traditional pointing material made from sand and a linseed-oil-based binder, used between timber frames and stone or brick.

Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status.
Sand mastic in Ringwood
Sand mastic suits most period window surrounds. Newer frames generally get a flexible sealant instead, and we’ll talk through which suits your home. If you are dealing with crumbling sand mastic round a window and open joints round the window box, we can put it right, on period & listed homes, sash and case windows and brick reveals alike.
In smaller places like Ringwood, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. Each frame material needs the right sealant against the right wall.

Why act early in Ringwood
Draughts round a sash window are not always the sashes. Open mastic joints round the box can let air in, and renewing the mastic closes them. Homes in smaller places like Ringwood 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.
Doing several joints on one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

Different surfaces, different methods
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.
Sash and case windows
Most of our sand mastic work is on sash windows. Each joint round the box is raked out and renewed.
What affects the quote in Ringwood
Some jobs are bigger than they look, and some smaller. The main factors:
- Whether old sealant or filler has to be cut out
- Which sealant suits the joint
- When we can work, for business premises
- Any mould that needs treating
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
What to tell us for a quote
Photos by email are helpful but not essential. Please mention:
- Where the job is, and your postcode
- The problem you’ve noticed
- Pictures of the joints, sent by email
- Whether it’s a home or a business
Quotes start with a quick conversation. Describe the problem, the location and the size of the job. When it suits you, call 0345 464 0079 or send us an email.
The process
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours for a single window, longer for several, and the area is left clean. For a job in Ringwood, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First, we look at the surrounds with you and agree what needs doing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- On commercial sites, let us know about site rules
- Mention any leaks or damp you’ve noticed
Ask for a quote

Related advice
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Sort the mastic before the decorators arrive
- Avoid heavy scraping on the mastic joint
- Do not paint over the new mastic
- Keep sills and gutters clear so water drains away
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall so early renewal protects both.

Frames and glazing around Ringwood
Historic houses like Avon Tyrrell House (about 3.6 miles south-east) are a reminder that the area around Ringwood has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For site and facilities teams at buildings such as Ringwood School, the mastic around its windows and doors needs looking after like any other building’s. If you live in an older home near Trinity Congregational Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
