- Cracked internal joints between frame and plaster
- Cracked or shrunken mastic around the frame
- Water coming in at the bottom corners of a door
The process
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take anything from an hour or two to a full day, depending on how many frames there are. Somewhere as small as Worlds End, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away, along with any loose debris.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
How to prepare
- Let us know about parking restrictions
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about any previous sealing or DIY attempts

Advice
Window mastic in Worlds End, done properly
The new joint does not have to be white. White, brown, anthracite grey, black and clear sealants are all available, so the line suits the frame instead of standing out. We are often asked to deal with whistling draughts around closed windows and old mastic that has gone black or come away, on composite doors, uPVC windows and patio & French doors.
Somewhere as small as Worlds End, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
We stand behind the work with a 12-month guarantee, so you are covered after we’ve gone.

DIY sealant or a professional job?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
If you are 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 does not work out, we can still put it right.
Why deal with it now?
A quick bead over the top of old mastic looks like an easy fix, but it won’t grip old, dirty sealant. It soon lifts and the leak carries on behind it. Proper resealing starts with removing the old joint. Older cottages and farmhouses around Worlds End can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Quotes for window mastic in Worlds End
Every job gets its own quote. These are the things that affect it:

- Whether it has been sealed before

Call for a quick quote, or email us if that is easier. Tell us about the joints that need doing and we will explain what’s involved.

Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Keep solvents and bleach off the sealant
- Don’t aim a pressure washer at the joints
- Wash the frames with mild soapy water
- Keep drainage slots and sill grooves clear
Silicone cannot generally be painted, so if you are planning to paint the frames or walls, tell us beforehand. We can use a paintable sealant where that matters.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. A new joint closes it up.
