DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

What the job involves on each surface
Timber door frames
Sand mastic is used round timber door frames too. The method is the same as for windows.
Period and listed homes
Many older homes were built with sand mastic round the windows. If your home is listed, ask your local planning authority about consent.
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Go gently near the mastic when preparing windows
- Keep sills and gutters clear so water drains away
- Ask a joiner to look at soft timber first
- Renew mastic before redecorating the windows
Don’t run silicone over the new mastic. If you see a crack, ask us to take a look before trying a quick fix.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.
