Why it’s worth doing now in Inverlochy
Cement-based fillers and modern sealants don’t always suit a period surround. Sand mastic matches what was there and that can be important for listed homes. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
Why book with us
- Tidy, careful work
- Arbo and Everbuild products
- Anti-fungal sanitary silicone in wet areas
- Full insurance on every job

About our sand mastic in Inverlochy
Burnt sand mastic is a traditional material that sits naturally against stone and brick. It’s a good fit for period properties, where modern sealant can look out of place. We work on timber door frames, brick reveals and tenement windows, and common reasons people get in touch are old sand mastic that has cracked, crumbled or fallen out and failed mastic on an exposed elevation.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Exposed frames and sills take the full force of wind-driven rain.
We stand behind the work with a one-year guarantee, so you’re not left on your own once the job is done.

DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
What the job involves on each surface
Sash and case windows
On a sash window, the mastic joint shows on the outside, so a neat, even finish matters.
Period and listed homes
Sand mastic is the like-for-like choice for many period homes. On listed buildings, check with your planning authority first.
What sealant work cannot fix
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Sashes that rattle, stick or will not open
- Decisions on consent for listed homes
- Decayed frames that need repair
If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think.
Joints and surfaces we work on
- Stone surrounds
- Tenement windows
- Brick reveals
- Period & listed homes
- Sash and case windows
- Timber door frames
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Ask the planning authority about consent for listed or conservation-area homes
- Do not paint over the new mastic
- Keep sills and gutters clear so water drains away
- Look over the window mastic once a year
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens.
What sand mastic looks like in Inverlochy
Inverlochy is within about 2 miles 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. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.
If you live in an older home near St Mary's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Letting a property close to Fort William station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about. For site and facilities teams at buildings such as Lochaber High School, larger buildings have plenty of frames, and the mastic around each one ages.

Common questions in Inverlochy
Does living near the coast affect sand mastic in Inverlochy?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are generally the first to need attention.
Do you work for landlords with property near Fort William station?
Yes. We work for letting agents and landlords as well as homeowners. Just send an email to info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear quote.
Can I paint the new mastic?
Traditional guidance is not to paint over sand mastic. Ask us before you decorate around it and we will talk you through it.
Do you offer different sealant colours?
Most of the time, yes. We will explain which colours are available.
Is it messy?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
What is sand mastic?
Sand plus a binder based on linseed oil. It’s built up in the joint by hand and shaped to suit the surround.
Should I use sand mastic or silicone?
Sand mastic normally suits period timber windows best. On modern frames, we’d normally use a flexible sealant.
How long does the job take?
Typically it takes a few hours per window, depending on the condition of the joints. Bigger jobs take longer.
