How we handle sand mastic in Garlinge Green
We work across Garlinge Green renewing sand mastic on sash windows and doors. Every joint is cleaned out and filled by hand for a neat, traditional finish. We work on brick reveals, tenement windows and sash and case windows, and the jobs we see most are mastic round period door frames that has failed and modern sealant on a period surround.
Homes in small places like Garlinge Green often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Look over the window mastic once a year
- Avoid patching sand mastic with silicone
- Ask a joiner to look at soft timber first
- Plan mastic work ahead of painting
Do not touch or press the mastic while it hardens. It forms a skin fairly soon but needs longer to fully harden.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens.
Why act early in Garlinge Green
Not every filler suits an old window surround. Sand mastic matches what was there and that can be important for listed homes. Around Garlinge Green, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
What you get with us
- Old sealant always removed completely
- Anti-fungal silicone where joints get wet
- Quality sealants from Arbo and Everbuild

Your questions about sand mastic in Garlinge Green
Is Garlinge Green within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Chartham station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done and you’ll get one quote.
Can new sealant go over the old?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Is it possible to take out silicone and use sand mastic instead?
Often, yes. Once the silicone is out and the joint prepared, sand mastic is applied by hand.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Can I choose the sealant colour?
We help you choose a colour that suits. The product needed can limit the range.
Is the work guaranteed?
Every job comes with our one-year guarantee.

Different surfaces, different methods
Period and listed homes
On a listed home or in a conservation area, the right material matters. Sand mastic is often the preferred finish.
Stone surrounds
Stone openings are rarely perfectly straight, so the joint varies in width. Sand mastic is shaped by hand to suit.

We keep the work tidy and contained to the joints we are treating, so you can carry on as normal. The job normally takes a few hours for a single window, longer for several.
