Window mastic in Crosshouse
Frames and walls don’t move together. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. That’s why the joint needs a flexible, low-modulus sealant rather than something rigid. We work on timber windows & doors, window sills and uPVC windows, and common reasons people get in touch are water coming in at the bottom corners of a door and mastic that’s falling out in pieces.
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.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Frames and glazing around Crosshouse
Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
If you look after a building such as Greenfaulds High School, its window and door frames need their mastic kept sound, just like a home’s.

Questions from Crosshouse
Do you work for landlords with property near Greenfaulds station?
Yes, we work for landlords and agents. Just email us at info@mrmastic.co.uk and tell us about the property, and we will send you a clear quote.
Is Crosshouse within the area you cover?
Yes. Crosshouse is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Crosshouse, along with the rest of our area.
How long does it take to reseal the windows on a house?
It depends on access, the old mastic and the size of the frames. We’ll tell you how long your job needs when we quote.
Is the new sealant paintable?
Most silicone cannot be painted. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
Do you do commercial work?
Yes. We can plan bigger jobs in stages.
Do you remove the old sealant?
Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status.
What we do, step by step
The work is kept neat and contained to the joints we are treating, so you can carry on as normal. Expect the work to take a morning for a couple of windows and a door, and we tell you how long to leave it before we go. For a place like Crosshouse, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
How to prepare
- Let us know if you’ve seen damp or leaks
- Try not to wet indoor joints just before the visit
- Move anything stored near the joints

When something else is needed
In fairness, there are a few things sealant won’t fix:
- Penetrating damp from a failed cavity tray or render
- Broken hinges, locks or handles
- Draughts through the window seals rather than the frame
Not sure which it is? You can send an email to info@mrmastic.co.uk and we will tell you honestly.
Surfaces we seal
- Aluminium frames
- Timber windows & doors
- Composite doors
- Window sills
- uPVC windows

Why act early in Crosshouse
Failed mastic is not a reason to replace sound windows. If the frames and glass are in good order, resealing the joints is often all that’s needed. Problems with the glass or gaskets are for a window company, and we’ll say so. 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 size of the job, how much old material has to come out and access to the work. We give a clear quote before any work starts, so you know where you stand.
What you get with us
- An ARBOMaster approved applicator

Signs you need window mastic in Crosshouse
Some failures date back to when the windows were fitted. Mastic laid onto dusty, damp or crumbling surfaces never bonded as it should, and it lets go sooner than it should.
If you can see any of these, it’s time to have the joints looked at:
- Sealant in the wrong colour for the frame
- Mastic that is falling out in pieces
- Gaps left after new windows were fitted
- Mastic that has split away from the wall
Rented homes near Greenfaulds station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

What the job involves on each surface
uPVC windows
uPVC expands and contracts noticeably with temperature, so we use a flexible, low-modulus sealant. We match white, brown, anthracite grey and black frames.
Patio & French doors
Patio and French doors have the longest joints on most houses. The threshold and the bottom corners take the most water, so we pay close attention there.
Work for landlords, hotels and businesses
Housing providers, facilities teams and property managers book us too in Crosshouse and across North Lanarkshire. We can quote a run of properties together.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
