How we handle window mastic in America Ground
Frames and walls don’t move together. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. Typical jobs include gaps where the sill meets the wall and gaps left after new windows were fitted, on window sills, patio & French doors and timber windows & doors.
Houses in smaller places like America Ground can stand more in the open than those in a built-up town. The mastic around frames on those walls tends to age faster.

When something else is needed
We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:
- Damp coming through the wall itself rather than the frame joint
- Soft or decayed wood in the frame
- A door that needs adjusting, rehanging or new seals
If you are not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer before booking.

What window mastic looks like in America Ground
America Ground is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Rented homes near Hastings station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. For site and facilities teams at buildings such as University School, its window and door frames need their mastic kept sound, just like a home’s. If you live in an older home near Holy Trinity Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Looking after it afterwards
Aftercare is simple:
- Use gentle cleaners on frames and sealant
- Repaint timber before it’s bare
- Don’t aim a pressure washer at the joints
- Air rooms to keep condensation down around windows
Silicone cannot generally be painted, so if you are planning to paint the frames or walls, tell us beforehand. There are paintable sealants for joints that need it.
Leaks generally show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.
Your questions about window mastic in America Ground
I let a flat near Hastings station. Can you help?
Yes. We work for landlords and agents as well as homeowners. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Does living near the coast affect window mastic in America Ground?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. Walls facing the sea are usually the first to need attention.
Does the work come with a guarantee?
Yes, with our one-year guarantee. A yearly look at the joints helps them last.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Can new sealant go over the old?
No. The old sealant always comes out first.
Can you match the sealant to my frames?
Yes. Grey and black frames get grey or black sealant, and wood-effect frames normally suit brown.
Where do you work from?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Can I paint over the new sealant?
Not if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
For landlords and businesses
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.

Composite doors
Draughts round the door leaf generally come from worn seals or adjustment, not the mastic. We’ll tell you if that’s what we find.
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the bottom joint sees the most water. Each is cleaned, backed where deep and resealed.
Why it’s worth doing now in America Ground
The work is quick compared with the damage it prevents: the visit takes anything from an hour or two to a full day, depending on how many frames there are. Wait for damp to appear and there may be plaster and decorating to sort out too. In an older home around America Ground, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, call 0345 464 0079 or send us an email and we will give you an honest view and a quote.

- Deep voids are backed, then the sealant is gunned in.
