Sand mastic for homes and businesses in Chalksole Green
Silicone on a period window often looks wrong and doesn’t suit the building. Sand mastic gives a finish that matches the age of the house, and we can replace one with the other. If you’re dealing with mastic dropping out of the joint and weathered mastic on the most exposed windows, we can help, whatever the surface.
In a village or hamlet like Chalksole Green, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

Why deal with it now?
If you’re redecorating, renew the mastic first. Paint over cracked mastic will not stop the gaps, and the new mastic is traditionally left unpainted. In a small place like Chalksole Green, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost depends on the size of the job, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts.

Work for landlords, hotels and businesses
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
What happens on the day
At the end, we look at the finished work together and tell you how long to leave it. The visit itself usually takes a few hours per window, depending on the condition of the joints, depending on the size of the job. For a village or hamlet like Chalksole Green, 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.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- For indoor joints, keep the area dry beforehand if you can
- On commercial sites, let us know about site rules

Common questions in Chalksole Green
I let a flat near Kearsney station. Can you help?
Yes, we work for landlords and agents. You can ring 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before work begins.
Does living near the coast affect sand mastic in Chalksole Green?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Can you work on commercial sites?
Yes. We can plan bigger jobs in stages to suit the site.
How long does sand mastic take?
Typically it takes a few hours for a single window, longer for several. Larger jobs naturally take longer.
Do you take out the old sealant first?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Is consent needed for window work on a listed home?
Checking first is sensible. Ask your local planning authority whether consent is needed for work on a listed home or in a conservation area.
Do you offer different sealant colours?
We’ll suggest a colour to suit the surroundings. The product needed can limit the range.
What do you need from me for a quote?
The location, the problem and the rough size of the job. If you can, email a few pictures.
Frames and glazing around Chalksole Green
Chalksole Green is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Historic houses like Acrise Place (about 3.6 miles west) are a reminder that the area around Chalksole Green has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
In the older streets around Church of St Anthony the Martyr, the joint between an old wall and a newer frame is normally the first place rain gets in. Rented homes near Kearsney station change hands often, and any sash windows need sound mastic to keep draughts and rain out.

Surface by surface
Period and listed homes
Period homes look their best with traditional materials, and sand mastic is one of them.
Tenement and terrace windows
In shared buildings, the windows may be part of a wider repair, so check who is responsible first.
Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Check the mastic when you check the paintwork
- Plan mastic work ahead of painting
- Keep sills and gutters clear so water drains away
- Take care around the mastic when scraping paint
Do not touch or press the mastic while it hardens. It forms a skin fairly soon but needs longer to fully harden.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.
