How we handle sand mastic in West Itchenor
For a listed home or one in a conservation area, ask your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. If you have cement or filler used on old window joints that has cracked and mastic round period door frames that has failed, we can help, on timber door frames, stone surrounds and sash and case windows alike.
Somewhere as small as West Itchenor, 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.
All our work comes with a 12-month guarantee.

Sand mastic in West Itchenor: local notes
West Itchenor is close to 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 older windows and doors, 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, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to St Nicholas' Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Should I try it myself first?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
FAQs for West Itchenor
Is West Itchenor within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you work for landlords with property near Bosham station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before we start.
Can you match the sealant colour?
Yes. White, clear and grey are common, and other colours are available for many products, and we will agree it with you first.
What information do you need?
A short description and the location, with pictures by email if possible. If we need more, we will ask.
Is it possible to take out silicone and use sand mastic instead?
In most cases. The silicone is cut out and the joint cleaned before the sand mastic goes in.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done and you will get one quote.
Is consent needed for window work on a listed home?
Speak to your local planning authority before work starts. Like-for-like sand mastic is often the preferred finish but the decision is theirs.
Is it OK to seal over old sealant?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.
Landlord and commercial work in West Itchenor
Hotels need rooms back in use, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
Do you need sand mastic in West Itchenor?
Previous repairs in cement or silicone often trap water or crack away. They don’t move with the timber, and they generally need raking out.
Any of these means the joints need attention:
- Gaps where the frame meets the masonry
- Patchy fillers round a sash window
- Cracked mastic round a front door frame
- Mastic worn away on windows facing the weather
For landlords with property near Bosham station, any sash windows need sound mastic to keep draughts and rain out.
What your quote should include
- Whether they’re fully insured
- How long to leave it before use
- What preparation is included
- What product goes in the joint
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Ask us before painting near the mastic
- Look over the window mastic once a year
- Clear gutters so water does not pour onto the windows
- Get any rot dealt with first
When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens.
