Sand mastic for sash & case windows in West Hill, Brighton and Hove
We cover West Hill for traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Modern sealant on a period surround
- Mastic dropping out of the joint
- Draughts and rain around sash boxes
Should I try it myself first?
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.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Sand mastic in West Hill, done properly
On many period windows, sand mastic looks right and suits the building. Newer frames usually get a flexible sealant instead, and we will talk through which suits your home. We work on tenement windows, timber door frames and period & listed homes, and common reasons people get in touch are draughty sash windows at the surround and mastic dropping out of the joint.
Homes around West Hill range from older properties to newer houses, and their windows range just as widely. The right sealant depends on the frame and on what it sits in.
The work is covered for a year after we finish. If anything is not right with it, call 0345 464 0079 or drop us an email.

How the visit works
When we arrive, we start by going over the job with you. Surfaces next to the work are protected before any work begins. The work generally takes anything from a few hours to a full day, depending on how many windows. Parking around West Hill is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Mention any sign-in or site rules at work premises
- Tell us if parking is tricky

West Hill: your questions answered
Can you help a landlord with a rental near Brighton station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before we start.
Does the coastal weather in West Hill affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Can I do it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Should I check with the council before work on a listed or conservation-area home?
Yes, it’s worth checking. Your local planning authority can say if consent is needed for listed or conservation-area properties.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
Can old silicone round a sash window be swapped for sand mastic?
Yes. The silicone is cut out and the joint cleaned before the sand mastic goes in.
Do you cover West Hill?
Yes. We work in West Hill and the rest of Brighton and Hove, as part of our work across South East England, London and Scotland. For a quote, call 0345 464 0079 or drop us an email.
What happens if it’s left?
If you’re redecorating, renew the mastic first. Paint over cracked mastic will not stop the gaps, and the new mastic is traditionally left unpainted. Around West Hill, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part.

West Hill homes and the weather
West Hill 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. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Schools such as St Paul's CofE Primary School and Nursery are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. For an older house near a landmark such as Galeed Strict Baptist Chapel, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Do you need sand mastic in West Hill?
Shallow joints are a common cause. Mastic that’s too thin cracks and drops out so we make sure the new mastic is the right thickness.
If you can see any of these, it’s time to have the joints looked at:
- Weathered mastic on the most exposed windows
- Crumbling sand mastic round a window
- Wind and rain getting in round a sash window
- Gaps where the frame meets the masonry
Rented homes near Brighton station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.
