Sand mastic for homes and businesses in Oakgrove
Our applicators renew the sand mastic around sash and case windows and doors set in stone or brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. We work on tenement windows, stone surrounds and brick reveals, and the jobs we see most are gaps round a timber door in stone or brick and gaps where the frame meets the masonry.
Homes around Oakgrove range from older properties to newer houses, and their windows range just as widely. The right sealant depends on the frame and on what it sits in.

How it works
All our tools and materials come with us in the van. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours per window, depending on the condition of the joints. For a job in Oakgrove, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We check the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.
- 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.
- The finish is dressed so it sits neatly against the stone or brick.
How to prepare
- Mention if the joints have been sealed before
- Tell us about any water getting in
- Let us know about stairs, lifts or work at height

Advice
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
When it is not the sealant
In fairness, there are a few things sealant will not fix:
- Broken panes
- Sashes that need overhauling
- Whether work needs listed building consent
If in doubt, call 0345 464 0079 or send us an email and we will say what we think.
Surfaces we seal

How the job changes by surface

Brick reveals
