Sand mastic in Middleton, done properly
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant, and we’ll talk through which suits your home. If you are dealing with wind and rain getting in round a sash window and old cement repairs round a window that have failed, we can put it right, on timber door frames, stone surrounds and brick reveals alike.
Outdoor sealant needs dry, clean surfaces, so work on frames around Middleton is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or send us an email.

I rent my home. Can I book you?

The usual advice is to leave sand mastic unpainted. Ask us before you decorate around it and we will advise.

Leave it or put it right?
Before painting the windows, it pays to renew the mastic. Painting over failed mastic doesn’t seal it and traditional guidance is to leave the new mastic unpainted. Older cottages and farmhouses around Middleton can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we’ll explain what it covers.

How the visit works
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours for a single window, longer for several. For a village or hamlet like Middleton, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We check the window surrounds and agree which joints need renewing.
- Old, loose mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.
Getting ready for the visit
- Mention if the joints have been sealed before
- For business premises, tell us about site rules or sign-in
- For indoor joints, keep the area dry beforehand if you can

Can I do it myself?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.

For landlords and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we are fully insured for the work.
Middleton homes and the weather
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For site and facilities teams at buildings such as Longparish Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s. Homes close to Church of St Nicholas include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you let a flat or house near Whitchurch (Hampshire) station, cracked sand mastic around sash windows lets in the draughts tenants complain about.
