Sand mastic for homes and businesses in Bishopstoke
A silicone bead around a sash window can look out of place and is not always the right material. Sand mastic is the traditional choice and we can swap the silicone for it. Common call-outs are for patchy fillers round a sash window and crumbling sand mastic round a window, on stone surrounds, sash and case windows and tenement windows.
In smaller places like Bishopstoke, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. The right sealant depends on the frame and on what it sits in.
There’s a 12-month guarantee on every job.

Bishopstoke questions
Can you help a landlord with a rental near Eastleigh station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Will you come out to Bishopstoke?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

Only a few details: the address or postcode, what’s wrong and any access issues. Then ring 0345 464 0079 or email us.
What is sand mastic?
Sand mastic is a traditional material for pointing round windows and doors. It’s made with sand and a linseed-oil-based binder.
Can you work on commercial sites?
Yes. We’ve worked for hotels, offices and other businesses.
Can sand mastic be painted?
Sand mastic is normally left unpainted, as guidance on traditional windows advises. Talk to us before any painting near it.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.

DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Leave the new mastic unpainted
- Ask a joiner to look at soft timber first
- Take care around the mastic when scraping paint
- Check the mastic when you check the paintwork
Avoid painting over the new mastic, which is the traditional advice. If you are redecorating, ask us first.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.
How it works
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the work takes a few hours per window, depending on the condition of the joints for a typical job. In a smaller place like Bishopstoke, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.
How to prepare
- Mention any sign-in or site rules at work premises
- Tell us about any previous sealing or DIY attempts
- Keep pets and children clear of the area while we work

What happens if it’s left?
New mastic over crumbling mastic will not hold. We remove the loose material first so the new work lasts. In a smaller place like Bishopstoke, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
The cost depends on the amount of work, how much old material has to come out and how easy the joints are to reach. We give a clear quote before we start.

Frames and glazing around Bishopstoke
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as South Stoneham House (about 3 miles south-west) nearby, there’s older building stock in the area around Bishopstoke as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Managing a site like Stoke Park Junior School? Then larger buildings have plenty of frames, and the mastic around each one ages. If you live in an older home near St Paul's, the joint between an old wall and a newer frame is normally the first place rain gets in.
