What the job involves on each surface
Window sills
The end joints of a sill tend to fail before the rest. We reseal them so rain cannot run into the wall.
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A neat, narrow bead in a colour to match keeps the clean look.
Window mastic for homes and businesses in Calderwood
Behind a thin line of old mastic there’s sometimes a deep void. Packing it solid with sealant gives a joint that can’t flex, so deep gaps get backing rod first. That way the new bead bonds to the frame and the wall only. We’re often asked to deal with sealant in the wrong colour for the frame and old mastic that has gone black or come away, on uPVC windows, timber windows & doors and patio & French doors.
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.
Each job carries a 12-month guarantee, large or small.

What we do, step by step
When we arrive, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before any work begins. Most jobs take a few hours for a few frames, or a day or more for a whole house. Outdoor work around Calderwood depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints

What window mastic looks like in Calderwood
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
Historic houses such as Howden House, about 2.8 miles west, show how far back building around Calderwood goes. For site and facilities teams at buildings such as Our Lady's High School, its window and door frames need their mastic kept sound, just like a home’s.

Leave it or put it right?
Failed mastic is not a reason to replace sound windows. Where the frames are sound, new mastic normally deals with draughts and leaks at the edges. If we find failed glass units or worn seals, we’ll tell you. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
The cost depends on the amount of work, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts.

Questions from Calderwood
Do you work for landlords with property near Kirknewton station?
Yes, rental work is part of what we do. You can send an email to info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before any work starts.
Do you cover smaller places like Calderwood?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
How much does window mastic cost in Calderwood?
It depends on the job, so we quote each one individually. For a quick quote, drop us a line at info@mrmastic.co.uk and tell us what needs doing and where.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Where are you based?
We work from Crawley. We cover Calderwood and the rest of West Lothian, along with the rest of our area.
Can you seal over the old sealant?
No, it won’t last. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
Which products do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Do you seal inside as well as outside?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We can do either or both.
When to call us in Calderwood
Plenty of failed mastic was poorly applied in the first place. Mastic laid onto dusty, damp or crumbling surfaces didn’t grip properly, and it lets go sooner than it should.
Most people get in touch after spotting something like this:
- Cracked or shrunken mastic around the frame
- Draughts coming in around windows and doors
- Rushed sealant from a window installation
- Black, perished sealant on frames
Rented homes near Kirknewton station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
