About our sand mastic in Paynes Green
Sand mastic skins over fairly quickly but full hardening takes longer. Traditionally, sand mastic is left unpainted and we’ll advise if you are redecorating. We work on sash and case windows, timber door frames and brick reveals, and people most often call us about weathered mastic on the most exposed windows and cracked mastic round a front door frame.
Mastic can only go onto a dry, clean joint, so window work in Paynes Green is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

The process
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it normally takes a few hours per window, depending on the condition of the joints. Somewhere like Paynes Green needs a little journey planning: 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 look at the surrounds with you and agree what needs doing.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- The mastic is mixed, pressed into the joint by hand and shaped.
- We dress the surface so it sits neatly against the masonry.
How to prepare
- Tell us if parking is tricky
- Let us know if you’ve seen damp or leaks
- Clear the area around the work

Will the old sealant be removed?

Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
Is it possible to take out silicone and use sand mastic instead?
Normally, yes. Once the silicone is out and the joint prepared we point it with sand mastic.

DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Why act early in Paynes Green
Filling over old, loose mastic does not last. Raking out and preparing the joint gives it a sound base so the new work lasts. Where a wall is exposed, as many are in small places like Paynes Green, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
The cost depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.
