Why it’s worth doing now in Buckland
Gaps round a sash window let in rain and draughts. Water can get to the frame and the masonry so renewing it early protects the window. Around Buckland, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Doing several joints on one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will give you a clear quote for the lot.

Some old mastic was never deep enough. A thin layer does not hold well, which is why we pack deep voids first and get the depth right.
Most people get in touch when they notice one of these:
- Gaps where the frame meets the masonry
- Old sand mastic that has cracked, crumbled or fallen out
- Mastic worn away on windows facing the weather
- Draughty sash windows at the surround
For site and facilities teams at buildings such as Freman College, its window and door frames need their mastic kept sound, just like a home’s.

How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from a few hours to a full day, depending on how many windows, and the area is left clean. Somewhere as small as Buckland, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Keep children and pets away from the work area
- Mention if the joints have been sealed before

Advice
Buckland homes and the weather
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.
Rented homes near Royston station change hands often, and any sash windows need sound mastic to keep draughts and rain out. Homes close to St Andrew's Church include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.

DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
When something else is needed
A few problems are outside what sealant work can do:
- Masonry that needs repairing
- Sash cords, weights and draught-proofing of the sashes
- Broken panes
