How sand mastic works in West Berkshire

Fresh sand mastic forms a skin quite soon but full hardening takes longer. Traditional guidance is not to paint over it and we’ll advise if you’re redecorating. Typical jobs include old cement repairs round a window that have failed and gaps round a timber door in stone or brick, on brick reveals, period & listed homes and timber door frames.

There isn’t much for you to do on the day. Show us the job and we will take it from there. The work itself takes a few hours for a single window, longer for several, including the tidy-up.

First we agree which joints need doing.
Old mastic and any loose material are raked out.
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 we quote

The cost depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts.

Windows and doors across West Berkshire

From Newbury, Thatcham and Burghfield Common to its smaller places, West Berkshire has windows and doors of every age and material. The mastic around all of them ages, and it’s usually the first thing to let the weather in.

London and the South East are among the drier parts of the UK, though outside sealant still needs a dry, clean joint, so work across West Berkshire is planned around the weather.

Newbury: Managing a site like St Nicolas C.E. Junior School? Then its window and door frames need their mastic kept sound, just like a home’s. If you live in an older home near St Nicolas Church, the joint between an old wall and a newer frame is normally the first place rain gets in.

Leave it or put it right?

Not every filler suits an old window surround. Sand mastic is the like-for-like choice, which can matter on listed and conservation-area homes.

Should I try it myself first?

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Looking after it afterwards

After the cure time, these simple habits help:

Check with your local planning authority if your home is listed
Clear gutters so water doesn’t pour onto the windows
Go gently near the mastic when preparing windows
Plan mastic work ahead of painting

Don’t run silicone over the new mastic. If you see a crack, ask us to take a look before trying a quick fix.

Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.

Signs you need sand mastic

Paint, silicone or cement used over old mastic causes problems. They do not suit the joint, and they generally need raking out.

Any of these means the joints need attention:

Draughts and rain around sash boxes
A silicone bead on a sash window that spoils the look
Window mastic to renew ahead of painting
Failed mastic on an exposed elevation

West Berkshire questions

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 I paint the new mastic?

Sand mastic is normally left unpainted, as guidance on traditional windows advises. Ask us before decorating.

Which products do you use?

We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we’re using.

Do you offer different sealant colours?

Generally, yes. White, clear and grey are common, and other colours are available, and we agree the colour with you before work begins.

Do you remove the old sealant?

Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.

I’m a tenant. Can you help?

Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.

Can I do it myself?

Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
