How we handle window mastic in Melvich
Behind a thin line of old mastic there’s sometimes a deep void. Filling it with sealant alone leaves a joint that can’t move properly, so deep gaps get backing rod first. The sealant then grips the two sides it should. We work on uPVC windows, patio & French doors and composite doors, and people most often call us about rushed sealant from a window installation and cold air getting in at the frame edge.
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.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

What the job involves on each surface
Composite doors
Composite doors are normally hung in an uPVC-type frame, and the joint around it is sealed like a window. We match the colour to the frame.
Timber windows & doors
Wood swells when it’s wet and shrinks when it dries, so the joint must stay flexible. We seal onto sound, dry paintwork or timber.
Signs you need window mastic in Melvich
Sills take more water than any other part of a window, and the ends of the sill, where it meets the wall, are where it gets in. When that sealant fails, water gets into the wall or under the frame.
If you can see any of these, it’s time to have the joints looked at:
- Leaking joints at the ends of sills
- Untidy mastic left by window fitters
- Gaps between the frame and the inside reveal
- Cold air getting in at the frame edge
In and around Melvich, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

How the visit works
The work is kept neat and contained to the area we are working on, so you can get on with your day. The job normally takes a few hours for a handful of frames, longer for a whole house. In smaller Scottish places, parking is generally less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely, along with any loose debris.
- 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.
- The joint is shaped to shed water and the area tidied.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Let us know about parking restrictions
- Let us know about stairs, lifts or work at height

Melvich questions
Does the coastal weather in Melvich affect outside sealant?
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.
Can you do window mastic in Melvich?
Yes. Our work covers the whole of Scotland, and Melvich is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Can you get sealant to suit coloured frames?
Yes. Anthracite grey, black, brown and white cover most frames, with clear as an option.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Can resealing stop a draught around my window?
It will if the frame joint is the problem. We find where the air is coming from before we reseal.
Do you do commercial work?
Yes. We can plan bigger jobs in stages.
How long should I leave it?
Cure times vary by product and the temperature. We tell you how long to leave it before we go.
Frames and glazing around Melvich
Melvich is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around window and door frames, especially on the side facing the sea. 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.
Whether the job is in Melvich itself or nearby, the right material for each joint matters as much as a neat finish.

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Keep jet washers away from the mastic
- Look round the frames every year or so
- Clean frames with a soft cloth and soapy water
- Keep drainage slots and sill grooves clear
Keep the new mastic undisturbed while it cures, for as long as we advise. Keep jet washers away from the frames.
A small gap around a frame only grows. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. Resealing closes it.

Landlords, agents and businesses in Melvich
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
Landlords and agents in Melvich can book us as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
Why it’s worth doing now in Melvich
A quick bead over the top of old mastic looks like an easy fix, but new sealant cannot bond to old, crumbling mastic. It soon lifts and the leak carries on behind it. Proper resealing starts with removing the old joint. In an older home around Melvich, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before work begins.
