Sand mastic for sash & case windows in Lake, Isle of Wight
Sand mastic for Lake and the surrounding area: the right sealant, proper preparation and a neat finish. Call for a quick quote.
- Mastic that needs renewing before redecorating
- Crumbling sand mastic round a window
- Failed mastic on an exposed elevation
Why deal with it now?
Silicone might seem the quicker option, but it can look wrong on a period surround. Sand mastic is the traditional material and blends with the stone or brick. Around Lake, 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.
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and agree the price before starting.

How we handle sand mastic in Lake
We work across Lake renewing sand mastic on sash windows and doors. Each joint is raked out, prepared and pointed by hand, finished to suit the masonry. If you have wind and rain getting in round a sash window and gaps between timber frames and stone or brick, we can put it right, on sash and case windows, tenement windows and timber door frames alike.
In a smaller place like Lake, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. That is hard on the mastic around frames and sills.
Big or small, you get the same 12-month guarantee.

Common questions in Lake
Is sand mastic in a coastal place like Lake any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Do you work for landlords with property near Lake 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 will give you a fixed price before we start.
Do you work in Lake?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland.
Do I need permission for sand mastic on a listed building?
Your local planning authority is the one to ask. They decide whether consent is needed for work to your windows.
Can I choose the sealant colour?
Usually, yes. White, clear and grey are common, and other colours are available, and we agree the colour with you before any work starts.
Are you fully insured?
Yes, we’re fully insured for domestic and commercial work.
Can you do several jobs on one visit?
Yes. Just list everything you need and you’ll get one quote.
Can I paint the new mastic?
It’s traditionally left unpainted, which is what traditional guidance recommends. Talk to us before any painting near it.
DIY versus a professional finish
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, then guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, 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.
Different surfaces, different methods
Stone surrounds
Stone surrounds suit sand mastic well. It finishes to look like part of the surround.
Tenement and terrace windows
Windows above ground floor need the right access. Let us know the floor and we will confirm access.
Lake homes and the weather
Lake 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. With historic houses such as Rylstone Manor (about 1.7 miles south) nearby, there’s older building stock in the area around Lake as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Rented homes near Lake station change hands often, and any sash windows need sound mastic to keep draughts and rain out. If you look after a building such as Broadlea Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Work for landlords, hotels and businesses
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.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
What sealant work cannot fix
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Masonry that needs repairing
- Sashes that rattle, stick or won’t open
- Planning or listed building consent (your local planning authority decides)
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think before you book.

Common problems we fix in Lake
Water gets into small cracks in the mastic and pushes it out. Exposed elevations normally fail first.
People normally contact us when they notice one of these:
- A silicone bead on a sash window that spoils the look
- Failed mastic on an exposed elevation
- Gaps between timber frames and stone or brick
- Gaps round a timber door in stone or brick
If you live in an older home near Church of The Good Shepherd, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

How the visit works
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes anything from a few hours to a full day, depending on how many windows, depending on the size of the job. Parking around Lake is usually easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- We check the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.
- Deep voids are packed so the mastic is the right thickness.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
Preparing for the visit
- Tell us if parking is tricky
- Let us know if you’ve seen damp or leaks
- For indoor joints, keep the area dry beforehand if you can
