Window & door mastic in Skinflats, Falkirk

Why deal with it now?
Once mastic fails, rain can get between the frame and the wall. Over time that can mean damp patches, damaged plaster and rotting timber. Resealing now is a small job by comparison. In a place like Skinflats, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Combining jobs into one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

Window mastic for homes and businesses in Skinflats
Around Skinflats we seal all kinds of frames: from uPVC casements to timber and aluminium, along with patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. We are often asked to deal with hard, cracked sealant around windows and water coming in at the bottom corners of a door, across uPVC windows, timber windows & doors and composite 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.
You’re covered for a year from the day we finish. If there’s a problem with it, please drop us a line at info@mrmastic.co.uk.

Landlord and commercial work in Skinflats
In hotels, rooms out of use cost money, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.
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.
What sealant work cannot fix
We won’t take on work that won’t last, so these are the limits:
- Damp coming through the wall itself rather than the frame joint
- A door that needs adjusting, rehanging or new seals
- Soft or decayed wood in the frame
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly.
Where we work in Skinflats
- Window sills
- uPVC windows
- Aluminium frames
- Patio & French doors
- Timber windows & doors
- Composite doors
Surface by surface
Timber windows & doors
Wood swells when it’s wet and shrinks when it dries, so a flexible sealant is essential. The paint or stain needs to be sound where the sealant meets it.
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. Most leaks start at the bottom corners, so they get particular care.

Skinflats questions
Can you help a landlord with a rental near Falkirk Grahamston station?
Yes, rental work is part of what we do. Just send an email to info@mrmastic.co.uk and tell us about the property, and we will give you a clear quote.
Is window mastic in a coastal place like Skinflats any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Is the work guaranteed?
Yes, for 12 months. A yearly look at the joints helps them last.
Do you seal inside as well as outside?
Yes. Plenty of draughts come through the inside joint as well as the outside, so sealing both is often worthwhile.
Can you seal over the old sealant?
No, it will not last. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
What does window mastic cost?
It depends on the job, so we quote each one individually. To get one, send an email to info@mrmastic.co.uk and let us know what needs doing and where.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint.
The process
We keep the work tidy and contained to the joints we’re treating. The job usually takes a few hours for a few frames, or a day or more for a whole house, and we explain the cure time before we leave. Somewhere like Skinflats may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Getting ready for the visit
- Tell us about any water getting in
- Mention any tricky access
- For business premises, tell us about site rules or sign-in

Getting a quote is simple: let us know what needs doing and where, and roughly how big it is. A few pictures by email make the job easier to understand.
Related advice
Window mastic in Skinflats: local notes
Skinflats is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around window and door frames, especially on the side facing the sea. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
Managing a site like Graeme High School? Then its window and door frames need their mastic kept sound, just like a home’s.

What we are called out for in Skinflats
Water runs down the glass onto the sill, so the sill ends and the joint below the frame are common leak points. When that sealant fails, water gets into the wall or under the frame.
These are the problems we’re asked about most:
- Mastic that has split away from the wall
- Old mastic that has gone black or come away
- Cracked internal joints between frame and plaster
- Cold air getting in at the frame edge
If you let a flat or house near Falkirk Grahamston station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
