Sand mastic for homes and businesses in Murrell Green
Sand mastic skins over fairly quickly, but it takes longer to harden fully. Traditionally, sand mastic is left unpainted, so ask us before you decorate. If you have open joints round the window box and wind and rain getting in round a sash window, we can help, whatever the surface.
Mastic can only go onto a dry, clean joint, so window work in Murrell Green is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
We stand behind the work with a 12-month guarantee, so you are covered after we have gone.

Can I do it myself?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Ask us before painting near the mastic
- Have rotten timber repaired before new mastic goes in
- Check with your local planning authority if your home is listed
- Clear gutters so water doesn’t pour onto the windows
Don’t touch or press the mastic while it hardens. It skins over quickly but needs longer to fully harden.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.

How long does sand mastic take to go off?
It skins over fairly quickly but takes longer to harden fully. We will tell you what to expect for your job.
Should I check with the council before work on a listed or conservation-area home?
Your local planning authority is the one to ask. They’ll tell you if consent is needed for work to your windows.
Are you insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Can you seal over the old sealant?
No. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
Which products do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We’ll tell you what we are using and why.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is normally more efficient.
How it works
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take a few hours for a single window, longer for several. Somewhere as small as Murrell Green, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
Preparing for the visit
- Mention if the joints have been sealed before
- Mention any leaks or damp you’ve noticed
- Keep children and pets away from the work area

Sand mastic in Murrell Green: local notes
With historic houses such as Stratfield Saye House (about 4.9 miles north-west) nearby, there’s older building stock in the area around Murrell Green 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. 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.
For landlords with property near Winchfield station, cracked sand mastic around sash windows lets in the draughts tenants complain about. In the older streets around St John the Evangelist, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
What the job involves on each surface
Stone surrounds
Old stone surrounds are often uneven, so the joint varies in width. Sand mastic is shaped by hand to suit.
Timber door frames
Sand mastic is used round timber door frames too. We renew it the same way as on windows.
