Aftercare tips
After the cure time, these simple habits help:
- Check with your local planning authority if your home is listed
- Avoid heavy scraping on the mastic joint
- Have rotten timber repaired before new mastic goes in
- Avoid patching sand mastic with silicone
Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.
Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
How the visit works
There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the job takes a few hours per window, depending on the condition of the joints in most cases. In Bushwood Area of Leytonstone, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- 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.
Preparing for the visit
- Mention any parking rules near the property
- Mention any sign-in or site rules at work premises
- Tell us about any water getting in

Advice
Why deal with it now?
Not every draught comes from the sashes themselves. Open mastic joints round the box can let air in and new mastic seals them. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll go through it with you.
