How we handle sand mastic in Hollybushes
Fresh sand mastic forms a skin quite soon, but it takes longer to harden fully. Traditionally, sand mastic is left unpainted and we’ll advise if you are redecorating. We are often asked to deal with open joints round the window box and weathered mastic on the most exposed windows, across stone surrounds, sash and case windows and tenement windows.
Mastic can only go onto a dry, clean joint, so window work in Hollybushes is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Each job carries a 12-month guarantee.

Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Take care around the mastic when scraping paint
- Plan mastic work ahead of painting
- Ask us before painting near the mastic
- Find out about consent before window work on a listed home
Keep gutters and sills clear so water runs away from the surround. Water sitting against the mastic shortens its life.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
When something else is needed
Before you book, it’s worth knowing the limits too:
- Masonry that needs repairing
- Sashes that need overhauling
- Putty and glazing repairs
If you are not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer.

Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
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, and the work is guaranteed for a year.

In most cases you can choose. We’ll tell you which colours the right product comes in.
Can I do it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.

Yes. We are fully insured, and we have been doing sealant work for more than 20 years.

Windows and doors in Hollybushes
With historic houses such as Belmont House and Gardens (about 4.8 miles east) nearby, there’s older building stock in the area around Hollybushes 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. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around Church of St Mary and the Holy Cross, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Rented homes near Sittingbourne station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.
