Common problems we fix in Great Baddow
Sand mastic slowly weathers. It hardens, cracks and starts to come away from the frame or the masonry.
The problems people usually mention when they call are:
- Gaps between timber frames and stone or brick
- Old sand mastic that has cracked, crumbled or fallen out
- Modern sealant on a period surround
- Weathered mastic on the most exposed windows
In the older streets around Church of St Mary, the joint between an old wall and a newer frame is generally the first place rain gets in.

Why act early in Great Baddow
New mastic over crumbling mastic won’t hold. We remove the loose material first so the new mastic stays put. In an older home around Great Baddow, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

What happens on the day
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a single window, longer for several. Parking around Great Baddow is normally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- 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.

Frames and glazing around Great Baddow
Historic houses like Danbury Place (about 2.3 miles east) are a reminder that the area around Great Baddow has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Schools such as Baddow Hall Infant School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. Rented homes near Chelmsford station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.

Keeping the joints in good condition
After the cure time, these simple habits help:
- Find out about consent before window work on a listed home
- Renew mastic before redecorating the windows
- Clear gutters so water does not pour onto the windows
- Inspect the joints round the windows every year or so
Keep gutters and sills clear so water runs away from the surround. Water sitting against the mastic shortens its life.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.
