Can I do it myself?
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.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Honest limits
A few problems are outside what sealant work can do:
- Rotten sashes, sills or window boxes (a joiner’s job)
- Sashes that rattle, stick or will not open
- Whether work needs listed building consent
If you are not sure, just phone 0345 464 0079 or email us and we will give you a straight answer before you book.

Why act early in Stoke Mandeville
Not every filler suits an old window surround. Sand mastic is the like-for-like choice, which can matter on listed and conservation-area homes. Homes in smaller places like Stoke Mandeville can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.

What we do, step by step
We keep the work tidy and contained to the area we are working on. Expect the work to take a few hours for a single window, longer for several, and we explain the cure time before we leave. In a smaller place like Stoke Mandeville, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
Before we arrive
- Tell us about any water getting in
- For business premises, tell us about site rules or sign-in
- Keep pets and children clear of the area while we work

Keeping the joints in good condition
After the cure time, these simple habits help:
- Plan mastic work ahead of painting
- Take care around the mastic when scraping paint
- Ask us before painting near the mastic
- Find out about consent before window work on a listed home
Don’t touch or press the mastic while it hardens. It forms a skin fairly soon, but takes longer to harden fully.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall, so renewing it early is worth it.

What is sand mastic?
It’s the traditional filler for the joint round timber windows and doors. It’s made with sand and a linseed-oil-based binder.

You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
