Sand mastic for homes and businesses in Wootton
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. We work on timber door frames, stone surrounds and brick reveals, and people most often call us about silicone on a period window that looks wrong and mastic worn away on windows facing the weather.
Around Wootton, 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.
You’re covered for a year from the day we finish. If anything isn’t right with it, call 0345 464 0079 or send us an email.

Aftercare tips
Good habits help new joints last longer. A few tips:
- Do not paint over the new mastic
- Take care around the mastic when scraping paint
- Check with your local planning authority if your home is listed
- Look over the window mastic once a year
Avoid painting over the new mastic, which is the traditional advice. If you’re redecorating, ask us first.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.

What we do, step by step
The work is kept neat and contained to the joints we’re treating, so you can carry on as normal. Expect the work to take a few hours for a single window, longer for several, and we tell you how long to leave it before we go. Somewhere as small as Wootton, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Mention any tricky access
- Plan for the work area to be out of bounds to pets and children

Wootton homes and the weather
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Avon Tyrrell House (about 3.2 miles west) nearby, there’s older building stock in the area around Wootton as well as newer homes. 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.
Homes close to St John include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Why it’s worth doing now in Wootton
Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic suits the building and finishes neatly against the masonry. Around Wootton, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

Is Wootton in your area for sand mastic?

Can old silicone round a sash window be swapped for sand mastic?
Yes. We remove the silicone and clean the joint before the sand mastic goes in.
Is it possible to paint over sand mastic?
Traditional guidance is not to paint over sand mastic. If you’re redecorating the window, ask us first and we will talk you through it.
Are you ARBOMaster approved?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us, and we’re fully insured.
When will the new mastic be hard?
It skins over fairly quickly but takes longer to harden fully. We will tell you what to expect for your job.
Can you seal over the old sealant?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. We remove it all first.
DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
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 does not work out, we can still put it right.
