What happens if it’s left?
The work is quick compared with the damage it prevents: the visit takes most of a day for a typical house, less for a few frames. Wait for damp to appear and there may be plaster and decorating to sort out too. Where a wall is exposed, as many are in small places like East Donyland, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

Window mastic in East Donyland, done properly
Most frames have an outside joint and an inside one. Outside, the mastic keeps rain out; inside, the joint between frame and plaster stops draughts and tidies the reveal. Either or both can be done. If you are dealing with cracked or shrunken mastic around the frame and whistling draughts around closed windows, we can put it right.
Homes in small places like East Donyland often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
Each job carries a 12-month guarantee, large or small.

What window mastic looks like in East Donyland
East Donyland is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around window and door frames, especially on the side facing the sea. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you let a flat or house near Wivenhoe station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Schools such as St Lawrence Church of England Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Your questions about window mastic in East Donyland
Do you cover smaller places like East Donyland?
Yes. East Donyland is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
I let a flat near Wivenhoe station. Can you help?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear quote.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Will there be a smell?
Possibly a little. It fades as the sealant cures, and ventilation helps.
Is the new sealant paintable?
Not if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you do not need to watch us work.
How long does it take to reseal the windows on a house?
It depends on access, the old mastic and the size of the frames. You will know the timing when we quote.
Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can go on one quote.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
The process
We keep the work tidy and contained to the joints we are treating, so you can carry on as normal. Expect the work to take anything from an hour or two to a full day, depending on how many frames there are. For a village or hamlet like East Donyland, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by checking each window and door with you.
- Next the failed sealant is cut away and the joint cleaned.
- Where gaps are deep, backing rod goes in first.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- We clear up and check every joint is fully closed.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Let us know if you’ve seen damp or leaks
- Clear items away from the joints we are working on

Signs you need window mastic in East Donyland
Plenty of failed mastic was poorly applied in the first place. Mastic laid onto dusty, damp or crumbling surfaces didn’t grip properly, and it lets go sooner than it should.
Common reasons people contact us include:
- White mastic on grey or black frames
- Mastic that has split away from the wall
- Black, perished sealant on frames
- Whistling draughts around closed windows
Homes close to Church of St Lawrence include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

- What the cure time is
- Whether all the old sealant comes out first
