Sand mastic in Racton, done properly
If your home is listed or in a conservation area, check with your local planning authority if consent is needed before window work. Like-for-like sand mastic is often the preferred finish. If you’re dealing with old cement repairs round a window that have failed and gaps round a timber door in stone or brick, we can help, on brick reveals, stone surrounds and timber door frames alike.
Around Racton, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or drop us an email.

How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Check with your local planning authority if your home is listed
- Do not run silicone over sand mastic
- Have rotten timber repaired before new mastic goes in
- Leave the new mastic unpainted
Leave the new mastic unpainted, which is the traditional advice. If you are redecorating, ask us first.
Sound mastic protects the frame. Once it fails, water can sit against the timber and timber that stays wet can rot.
Windows and doors in Racton
Racton is within about 3 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. Historic houses like Warblington Castle (about 3.9 miles south-west) are a reminder that the area around Racton has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Managing a site like Bourne Community College? Then the mastic around its windows and doors needs looking after like any other building’s. In the older streets around Racton Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What we do, step by step
We bring everything the job needs with us, so you do not need to buy or prepare anything. Once we have agreed what’s being done, we protect the area and start. It normally takes anything from a few hours to a full day, depending on how many windows. For a village or hamlet like Racton, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- 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.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Let us know about parking restrictions
- Mention any leaks or damp you’ve noticed

What sealant work can’t fix
In fairness, there are a few things sealant will not fix:
- Sash cords, weights and draught-proofing of the sashes
- Decayed frames that need repair
- Planning or listed building consent (your local planning authority decides)
If in doubt, phone 0345 464 0079 or email us and we will say what we think before booking.
What we seal
- Period & listed homes
- Sash and case windows
- Stone surrounds
- Timber door frames
- Tenement windows
- Brick reveals
What we’re called out for in Racton
Timber swells and shrinks with the weather. The movement cracks the mastic over time.
People generally contact us when they notice something like this:
- Failed mastic on an exposed elevation
- Patchy fillers round a sash window
- Silicone on a period window that looks wrong
- Wind and rain getting in round a sash window
For landlords with property near Southbourne station, older sash windows in a rental need their mastic kept sound to keep the weather out.

What else we do in Racton
Why it’s worth doing now in Racton
Not every filler suits an old window surround. Sand mastic matches what was there and that can be important for listed homes. Around Racton, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, phone 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.
