Sand mastic in Bainsford
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant and we will explain which is best for yours. If you have wind and rain getting in round a sash window and old sand mastic that has cracked, crumbled or fallen out, we can put it right.
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, so the mastic there works hard.
All our work is covered by a one-year guarantee, wherever you are in Falkirk.

Leave it or put it right?
New mastic over crumbling mastic won’t hold. We remove the loose material first so the new work lasts. 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.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

What we are called out for in Bainsford
Previous repairs in cement or silicone often trap water or crack away. They don’t move with the timber and we normally remove them.
Any of these means the joints need attention:
- Gaps where the frame meets the masonry
- Mastic that needs renewing before redecorating
- Silicone on a period window that looks wrong
- Old cement repairs round a window that have failed
Homes close to Grahamston United Church include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.

FAQs for Bainsford
Do you cover smaller places like Bainsford?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Does living near the coast affect sand mastic in Bainsford?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
I’m a tenant. Can you help?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
Do you have insurance?
Yes, we’re fully insured for every job we do.
Can I choose the sealant colour?
Most of the time, yes. We’ll explain which colours are available and agree one before we start.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Can I paint the new mastic?
Sand mastic is normally left unpainted, as guidance on traditional windows advises. Talk to us before any painting near it.
What guarantee comes with the work?
Our 12-month guarantee applies on every job.
How we quote for sand mastic
The price is agreed before any work begins. It takes into account:
- How many areas need sealing
- Working hours on commercial sites
- Whether old sealant or filler has to be cut out
- The product the joint needs
Doing several joints on one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.
Asking for a quote
Photos by email are helpful but not essential. Please mention:
- Whether it’s a home or a business
- What’s wrong with the joints now
- Any previous sealing or DIY work
- Roughly how big the job is
There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, email us at info@mrmastic.co.uk.
Can I do it myself?
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.
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.
Landlord and commercial work in Bainsford
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we’re fully insured.
Surface by surface
Tenement and terrace windows
Rows of sash windows on tenements and terraces often need renewing together. We work on single windows or whole elevations.
Brick reveals
Gaps between frame and brick let in rain and draughts. Renewing the mastic closes it.
What we do, step by step
On the day, we look over the joints with you first, so you know exactly what we are doing. Surfaces next to the work are protected before we start. Most jobs take anything from a few hours to a full day, depending on how many windows. Outdoor work around Bainsford depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- First, we look at the surrounds with you and agree what needs doing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- We dress the surface so it sits neatly against the masonry.
Before we arrive
- Let us know about stairs, lifts or work at height
- For business premises, tell us about site rules or sign-in
- Clear the area around the work

Advice
Bainsford homes and the weather
Bainsford is within about 3 miles of 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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
For landlords with property near Falkirk Grahamston station, any sash windows need sound mastic to keep draughts and rain out. Schools such as Comely Park School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
