Aftercare tips
Aftercare is simple, and it makes a real difference:
- Look over the window mastic once a year
- Avoid patching sand mastic with silicone
- Ask us before painting near the mastic
- Ask a joiner to look at soft timber first
Don’t run silicone over the new mastic. If you see a crack, ask us to take a look rather than patching it.
Once mastic starts to crumble, rain gets in. That water can reach the timber frame and the wall, so renewing it early is worth it.
Do you need sand mastic in Gardeners Green?
Most of it is simply age. Even well-laid mastic needs renewing in time, depending on exposure and upkeep.
If you can see any of these, it’s time to have the joints looked at:
- Crumbling sand mastic round a window
- Open joints round the window box
- Modern sealant on a period surround
- Draughty sash windows at the surround
Homes close to St Sebastian's Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

How we quote for sand mastic
There’s no set price list, because jobs vary so much. What we look at:
- Whether there’s mould to deal with
- Whether old sealant or filler has to be cut out
- Working hours on commercial sites
- Which sealant suits the joint
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and give you a clear price before any work starts.
What we need to know
To make quoting easier, let us know:
- How we’d reach the joints
- The type of property

Why it’s worth doing now in Gardeners Green
Filling over old, loose mastic does not last. Raking out and preparing the joint gives it a sound base so the new mastic stays put. Older cottages and farmhouses around Gardeners Green can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Why book with us
- Old sealant always removed completely
- 12-month guarantee on every job
