Window mastic in Bosham Hoe
The mastic around a window or door seals the gap between the frame and the wall. When it cracks, hardens or pulls away, draughts and rain get in. Our applicators cut it out and replace it with a flexible, weatherproof sealant. We’re often asked to deal with gaps between the frame and the inside reveal and gaps where the sill meets the wall, across window sills, composite doors and aluminium frames.
In a village or hamlet like Bosham Hoe, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
You get a one-year guarantee, the same in Bosham Hoe as everywhere else we work.

How the job changes by surface
Window sills
Masonry sills can have joints where water gets in, and the joint under the frame can let rain run behind. We seal those with a sealant suited to masonry.
Timber windows & doors
Wood swells when it’s wet and shrinks when it dries, so a flexible sealant is essential. We seal onto sound, dry paintwork or timber.
How the visit works
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes most of a day for a typical house, less for a few frames. For a village or hamlet like Bosham Hoe, 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.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Tell us about any previous sealing or DIY attempts
- Let us know if you’ve seen damp or leaks

Advice
When to call us in Bosham Hoe
Joints that are too thin or too deep fail early. A thin smear across a wide gap has nothing to it, and a gap filled solid cannot flex. Backing rod sets the right depth.
These are the problems we’re asked about most:
- Mastic that has split away from the wall
- Gaps where the sill meets the wall
- Draughts coming in around windows and doors
- Rushed sealant from a window installation
Homes close to The Parish Church of the Holy Trinity include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

- Whether the work is at height

What to tell us for a quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:

Bosham Hoe homes and the weather
Bosham Hoe 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, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Bosham station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

DIY versus a professional finish
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Your questions about window mastic in Bosham Hoe
Is Bosham Hoe within the area you cover?
Yes, Bosham Hoe is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Does living near the coast affect window mastic in Bosham Hoe?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are normally the first to need attention.
Can new window sealant be painted?
Most silicone can’t be painted. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
Is it messy?
No. We work neatly, protect the area around the joints and tidy up afterwards.
How much does window mastic cost in Bosham Hoe?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Can you seal the gap between the frame and the plaster indoors?
Yes. Draughts often come through the inside gap too, so it can be worth sealing both.
Can you seal over the old sealant?
No, because it fails. We remove every bit of old sealant first, so the new sealant bonds properly.
Will there be a smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
