Sand mastic in Aldermaston: local notes
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to Church of St Mary the Virgin include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame. For site and facilities teams at buildings such as Aldermaston C.E. Primary School, its window and door frames need their mastic kept sound, just like a home’s.

How the visit works
A visit follows a simple pattern: we check the joints, protect the area around them, do the work and clear up. It normally takes a few hours per window, depending on the condition of the joints. For a village or hamlet like Aldermaston, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.
Before we arrive
- Mention any sign-in or site rules at work premises
- Mention any parking rules near the property
- Where the joints are inside, avoid wetting them before we arrive

Different surfaces, different methods
Brick reveals
An open joint at a brick reveal lets weather in. New mastic seals the gap.
Sash and case windows
Most of our sand mastic work is on sash windows. Each joint round the box is raked out and renewed.
Do you need sand mastic in Aldermaston?
Timber frames move with the seasons. That movement opens up the mastic joint over time.
Most people get in touch when they notice something like this:
- Draughts and rain around sash boxes
- Silicone on a period window that looks wrong
- Mastic that needs renewing before redecorating
- Mastic round period door frames that has failed
Letting a property close to Aldermaston station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about.

DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
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.
Honest limits
We will not take on work that won’t last, so here’s what sealant cannot put right:
- Decisions on consent for listed homes
- Masonry that needs repairing
- Putty and glazing repairs
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly.
