Sand mastic in West Reading
If your home is listed or in a conservation area, check with your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. We work on stone surrounds, timber door frames and sash and case windows, and the jobs we see most are tired mastic found when preparing windows for paint and cement or filler used on old window joints that has cracked.
Many houses in smaller places like West Reading have conservatories, garden rooms or patio doors. Those joints need the same attention as the main windows.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

When something else is needed
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Sashes that need overhauling
- Planning or listed building consent (your local planning authority decides)
- Cracked or broken glass
If in doubt, phone 0345 464 0079 or email us and we will say what we think.

Sand mastic is the like-for-like choice for many period homes. On listed buildings, check with your planning authority first.
Timber door frames
Period doors in stone or brick openings are often pointed with sand mastic. The method is the same as for windows.
What sand mastic looks like in West Reading
Rainfall in the South East is lower than in much 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 Mapledurham House (about 2.8 miles north-west) nearby, there’s older building stock in the area around West Reading 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.
For landlords with property near Reading West station, any sash windows need sound mastic to keep draughts and rain out. For site and facilities teams at buildings such as Battle School, the mastic around its windows and doors needs looking after like any other building’s. Homes close to Church of St Mark include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Why act early in West Reading
Before painting the windows, it pays to renew the mastic. Painting over failed mastic doesn’t seal it, and the new mastic is traditionally left unpainted. Homes in smaller places like West Reading can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

Aftercare tips
A little care helps the new joints last. Our advice:
- Have rotten timber repaired before new mastic goes in
- Plan mastic work ahead of painting
- Ask us before painting near the mastic
- Inspect the joints round the windows every year or so
Leave the new mastic unpainted, as traditional guidance advises. If you’re redecorating, ask us first.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens.
The process
We bring everything the job needs with us, so you do not need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours for a single window, longer for several. For a job in West Reading, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Mention any leaks or damp you’ve noticed
- Let us know about earlier repairs to the joints
