What sealant work cannot fix
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Planning or listed building consent (your local planning authority decides)
- Sashes that need overhauling
- Damaged stone surrounds
If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think before you book.

About our sand mastic in Wemyss Bay
Across Wemyss Bay, we renew sand mastic around sash and case windows. Every joint is cleaned out and filled by hand for a neat, traditional finish. We work on tenement windows, timber door frames and brick reveals, and people most often call us about mastic that needs renewing before redecorating and modern sealant on a period surround.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

DIY versus a professional finish
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.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Signs you need sand mastic in Wemyss Bay
Scraping and sanding before painting can loosen old mastic. It’s often found when windows are being prepared for paint, which is a good time to renew it.
Most people get in touch after spotting one of these:
- Wind and rain getting in round a sash window
- Mastic that needs renewing before redecorating
- Gaps where the frame meets the masonry
- Modern sealant on a period surround
If you live in an older home near St Josephs Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Inspect the joints round the windows every year or so
- Clear gutters so water doesn’t pour onto the windows
- Avoid patching sand mastic with silicone
- Ask a joiner to look at soft timber first
When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.

FAQs for Wemyss Bay
Can you help a landlord with a rental near Wemyss Bay station?
Yes, we work for landlords and agents. You can send an email to info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before work begins.
Does living near the coast affect sand mastic in Wemyss Bay?
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.
Can sand mastic be painted?
It’s traditionally left unpainted, as guidance on traditional windows advises. Ask us before decorating.
Is there any odour?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
Is it worth trying it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we are fully insured.
What guarantee comes with the work?
Our 12-month guarantee covers every job.
Should I use sand mastic or silicone?
We will talk it through with you. Period homes often look best with sand mastic, and modern sealants suit newer frames.

Your quote is based on your job. We look at:
- Working hours on commercial sites
- The size of the job

Windows and doors in Wemyss Bay
Wemyss Bay 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. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. The west of Scotland is wetter than the east, so there’s plenty of rain for the mastic around older windows and doors to keep out.
For landlords with property near Wemyss Bay station, older sash windows in a rental need their mastic kept sound to keep the weather out.
