Window mastic in Clerkhill
There are two joints on most windows. Outside, the mastic keeps rain out; the internal joint closes the gap to the plaster and stops draughts. We seal one or both, depending on what’s needed. We work on window sills, timber windows & doors and patio & French doors, and common reasons people get in touch are cracked internal joints between frame and plaster and leaking joints at the ends of sills.
In and around a place like Clerkhill, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill.
Big or small, it’s backed by our one-year guarantee.

Looking after it afterwards
After the cure time, these simple habits help:
- Clean frames with a soft cloth and soapy water
- Clear any debris from frame drain holes
- Keep solvents and bleach off the sealant
- Avoid blasting the frames with a pressure washer
Check the drainage slots in the frames aren’t blocked, so rain drains out rather than building up at the sealant.
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 early resealing is worth it.

Honest advice matters more to us than a booking, so here’s what sealant can’t fix:

How it works
The work is kept neat and contained to the joints we’re treating. Expect the work to take most of a day for a typical house, less for a few frames, and we tell you how long to leave it before we go. In smaller Scottish places, parking is usually less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- First we look at every frame and agree the list.
- The old mastic is cut out and the surfaces cleaned back.
- Deep gaps are filled with backing rod to set the depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Every joint is checked before we leave.
How to prepare
- Mention any tricky access
- Tell us about any previous sealing or DIY attempts
- Keep children and pets away from the work area

Windows and doors in Clerkhill
Clerkhill is close to 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 window and door frames, especially on the side facing the sea. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
For jobs in and around Clerkhill, choosing the right material for each joint is as important as a tidy finish.

Surface by surface
Aluminium frames
Large aluminium doors have long joints down each side and across the head, and the bottom joint sees the most water. Each is cleaned, backed where deep and resealed.
uPVC windows
The frame is cleaned with a product that won’t harm the plastic, then the new bead is laid against the frame and the wall and tooled smooth.
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, 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.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.

Common problems we fix in Clerkhill
Sills take more water than any other part of a window, so the sill ends and the joint below the frame are common leak points. Failed sealant there lets rain into the wall or behind the frame.
Any of these means the joints need attention:
- Mastic that has split away from the wall
- Gaps where the sill meets the wall
- Cracked internal joints between frame and plaster
- Draughts coming in around windows and doors
In and around Clerkhill, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

Clerkhill: your questions answered
Does living near the coast affect window mastic in Clerkhill?
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.
Is Clerkhill within the area you cover?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
I’m a tenant. Can you help?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
What should I tell you?
Just the basics: the address or postcode, what’s wrong and any access issues. Then drop us a line at info@mrmastic.co.uk.
Will new mastic stop draughts?
It will if the frame joint is the problem. We check where the draught is before we start.
Do you work on first-floor windows?
Usually, yes. We plan safe access before the job.
Can you seal the gap between the frame and the plaster indoors?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We do one or both.
Can I paint over the new sealant?
Not if it’s silicone. Tell us your decorating plans and we’ll pick a sealant to suit.
