Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Keep sills and gutters clear so water drains away
- Renew mastic before redecorating the windows
- Take care around the mastic when scraping paint
- Get any rot dealt with first
When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall, so renewing it early is worth it.

Everything for the job comes with us, so a second trip is avoided where possible.

Windows and doors in Stones Green
Stones Green is within about 3 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Schools such as Wix and Wrabness Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. Historic houses such as Thorpe Hall, about 3.3 miles south, show how far back building around Stones Green goes.

If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.

Questions from Stones Green
Is sand mastic in a coastal place like Stones Green any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Will you come out to Stones Green?
Yes, Stones Green is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Where is Mr Mastic based?
Our base is in Crawley, and we work across South East England, London and Scotland.
Are you fully insured?
Yes. We are fully insured.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Do you work for landlords and businesses?
Yes, we do. Domestic, commercial and hotel work are all part of what we do.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
When will the new mastic be hard?
A skin forms quite soon, but full hardening takes longer. We’ll tell you what to expect for your job.
