Window mastic in Hairmyres
Over two decades of sealing frames has taught us which products suit which walls. We’re ARBOMaster approved and fully insured, and we give a one-year guarantee on the work. Common call-outs are for sealant in the wrong colour for the frame and old mastic that has gone black or come away, on window sills, aluminium frames and patio & French doors.
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.
Whatever the size of the job, it’s backed by our one-year guarantee in Hairmyres and across South Lanarkshire.

How long does it take to reseal the windows on a house?

It depends on the job. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
Can you match the sealant to my frames?
Generally, yes. Mention the frame colour when you ask for a quote and we will match it as closely as we can.
Will new mastic stop draughts?
Yes, where the draught is at the frame edge. We check where the draught is before we start.
When something else is needed
New sealant cannot fix everything, and we’ll tell you before we start. It will not solve:
- Damp coming through the wall itself rather than the frame joint
- A door that needs adjusting, rehanging or new seals
- Rotten timber, which needs a joiner first

Hairmyres homes and 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. Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
For landlords with property near Hairmyres station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. For site and facilities teams at buildings such as Duncanrig Secondary School, its window and door frames need their mastic kept sound, just like a home’s.

Aftercare tips
A little care helps the new joints last. Our advice:
- Avoid harsh chemicals near the mastic
- Keep jet washers away from the mastic
- Look round the frames every year or so
- Repaint timber before it’s bare
Clean the frames with mild soapy water, and keep solvents and harsh chemicals off the joint.
Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.
Leave it or put it right?
A quick bead over the top of old mastic looks like an easy fix, but it will not grip old, dirty sealant. It soon lifts and the leak carries on behind it. The old mastic has to come out. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

Advice
How the job changes by surface
Window sills
The end joints of a sill tend to fail before the rest. We reseal them so rain can’t run into the wall.
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. The threshold and the bottom corners take the most water, so they get particular care.
How we quote for window mastic
You’ll get a clear quote before we start. It takes into account:
- The amount of work
- Whether the work is at height
- The type of sealant required
- The old material and how stubborn it is
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What we need to know
Before you ask for a quote, have a think about:
- The rough size of the job
- If someone has resealed it before
- What’s wrong with the joints now
- Any access issues, like height or stairs
Every job is quoted individually, so the first step is telling us about yours. Just send an email to info@mrmastic.co.uk with the details and send pictures if you have them.
