- Cracked or shrunken mastic around the frame
- Mastic that’s falling out in pieces
- Water coming in at the bottom corners of a door
What we can’t put right
New sealant can’t fix everything, and we’d rather say so up front. It won’t solve:
- Faulty window hardware
- A door that needs adjusting, rehanging or new seals
- A failed sealed unit that has misted up
If in doubt, drop us a line at info@mrmastic.co.uk and we’ll say what we think.
Joints and surfaces we work on
- Window sills
- Patio & French doors
- Timber windows & doors
- Aluminium frames
- Composite doors
- uPVC windows
Window mastic in Inverinan
A window frame and the wall around it expand and shrink at different rates. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. That is why the joint needs a flexible, low-modulus sealant rather than something rigid. Common call-outs are for hard, cracked sealant around windows and a bead that doesn’t match the frame, across timber windows & doors, composite doors and uPVC windows.
Mastic can only go onto a dry joint, so outside work in Inverinan depends on the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
The work is covered for a year after we finish. If anything isn’t right with it, send an email to info@mrmastic.co.uk.

DIY versus a professional finish
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
How the visit works
Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes a few hours for a few frames, or a day or more for a whole house, depending on the amount of work. Outdoor work around Inverinan depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- 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.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- For business premises, tell us about site rules or sign-in
- Tell us about any water getting in

Advice
Why it’s worth doing now in Inverinan
Running fresh sealant over the old joint is tempting, but new sealant can’t bond to old, crumbling mastic. It soon lifts and the leak carries on behind it. The old mastic has to come out. In a place like Inverinan, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Rather than a set price list, 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.
Why book with us
- Domestic, commercial and hotel work
- Quality sealants from Arbo and Everbuild
- White, clear, grey or coloured to suit, where the product allows
- We never seal over old sealant

Windows and doors in Inverinan
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. The west of Scotland is wetter than the east, which means the mastic around window and door frames has to cope with a lot of rain.
