About our window mastic in West Mersea
Some gaps around frames are far deeper than they look. Filling it with sealant alone leaves a joint that cannot move properly, so deep gaps get backing rod first. The sealant then grips the two sides it should. We work on aluminium frames, window sills and uPVC windows, and common reasons people get in touch are mastic that’s falling out in pieces and cracked sealant at the sill ends.
Homes around West Mersea range from older properties to newer houses, and their windows range just as widely. Each frame material needs the right sealant against the right wall.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

For a job in West Mersea, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We check each frame and agree which ones need doing.
- We remove the old mastic and clean the frame and the wall.

Common questions in West Mersea
Do you cover West Mersea for window mastic?
Yes. We work across London and the South East, and West Mersea is part of that. You can call 0345 464 0079 or email us and let us know what needs doing, and we’ll give you a clear price.
Is West Mersea within the area you cover?
Yes. West Mersea is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do the sealants smell?
Possibly a little. It fades as the sealant cures, and ventilation helps.
Can I paint over the new sealant?
That depends on the product. Silicone isn’t paintable, but some hybrid sealants are. Mention any painting plans before any work starts.
Do I need to be at home?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
How long will my window job take?
The work takes anything from an hour or two to a full day, depending on how many frames there are. Access and the amount of old mastic make the biggest difference.
Do you remove the old sealant?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.
Where are you based?
Our base is in Crawley, and we work across South East England, London and Scotland.
Looking after it afterwards
So the new joints stay in good condition:
- Avoid harsh chemicals near the mastic
- Ventilate rooms so frames don’t stay wet inside
- Do not aim a pressure washer at the joints
- Clear any debris from frame drain holes
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.
Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.
Signs you need window mastic in West Mersea
Frames are never completely still. Sun on a frame makes it expand, and it contracts again overnight, while the masonry beside it stays put. If the sealant cannot stretch, it splits.
People normally contact us when they notice something like this:
- Mastic that has split away from the wall
- Old mastic that has gone black or come away
- Draughty joints inside around the window
- Damp patches on the reveal after heavy rain
For an older house near a landmark such as Church of St Peter and St Paul, the joint between an old wall and a newer frame is normally the first place rain gets in.

Frames and glazing around West Mersea
West Mersea is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around window and door frames, 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, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Schools such as Mersea Island School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
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 we can’t put right
New sealant can’t fix everything, and we’d rather say so up front. Sealant will not put right:
- A failed sealed unit that has misted up
- Damp problems in the wall away from the window
- A sash or casement that will not close properly
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think.
