About our sand mastic in Hoswick
We work across Hoswick renewing sand mastic on sash windows and doors. Every joint is cleaned out and filled by hand for a neat, traditional finish. We work on tenement windows, timber door frames and sash and case windows, and common reasons people get in touch are old sand mastic that has cracked, crumbled or fallen out and gaps between timber frames and stone or brick.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
Whatever the size of the job, you get the same 12-month guarantee.

Questions from Hoswick
Do you cover Hoswick for sand mastic?
Yes. We work across all of Scotland, and Hoswick is part of that. You can email us at info@mrmastic.co.uk and tell us what needs doing.
Is sand mastic in a coastal place like Hoswick any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Where do you work from?
We are based in Crawley, West Sussex, and we work across South East England, London and Scotland.
Do you hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
How much does sand mastic cost in Hoswick?
Size, access and the old material all affect the cost. Call for a quick quote.
Should I check with the council before work on a listed or conservation-area home?
Speak to your local planning authority before work starts. Sand mastic is often favoured as like for like, but they decide.
I rent my home. Can I book you?
We’re happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Do you work for letting agents?
Yes. We work in homes, commercial premises and hotels, and we are fully insured.
How it works
At the end, we look at the finished work together. The work normally takes anything from a few hours to a full day, depending on how many windows, depending on the amount of work. For a place like Hoswick, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Let us know if you’ve seen damp or leaks
- Tell us if parking is tricky

Different surfaces, different methods
Brick reveals
Loose mastic comes out and deep gaps are packed before pointing.
Sash and case windows
Most of our sand mastic work is on sash windows. We renew the mastic round each box.
How to look after the new joints
A little care helps the new joints last. Our advice:
- Plan mastic work ahead of painting
- Check with your local planning authority if your home is listed
- Leave the new mastic unpainted
- Ask a joiner to look at soft timber first
Keep paint scrapers and sanders off the mastic when redecorating. It can be damaged by heavy scraping.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.
What affects the cost of sand mastic
For a quick quote, just ask. The main things that affect it are:
- The product the joint needs
- Whether the work is at height
- When we can work, for business premises
- How many areas need sealing
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, email us at info@mrmastic.co.uk for an honest opinion and a quote.
What to tell us for a quote
You do not need to know the technical terms. Just tell us:
- Whether it’s a home or a business
- Any access issues, like height or stairs
- Where the job is, and your postcode
- Whether it has been sealed before
Call for a quick quote, or email us if that is easier. Describe what needs sealing and we’ll explain what’s involved and give you a clear price.

Other services in Hoswick
Hoswick homes and the weather
Hoswick is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.
Whether the job is in Hoswick itself or nearby, the right material for each joint matters as much as a neat finish.
