Questions from Newtonmore
Is Newtonmore within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Do you cover Newtonmore for window mastic?
Yes, Newtonmore is within the area we cover. We work across all of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear quote.
Can you do several jobs on one visit?
Yes. Just list everything you need and you’ll get one quote.
How long should I leave it?
That depends on the sealant used, so follow the cure time we give you.
Do you take out the old sealant first?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
What do you put in the joint?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We’ll tell you what we’re using and why.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
How we handle window mastic in Newtonmore
Every window and door frame has a gap around it, and mastic is what closes it. Once that seal fails, wind and rain find the gap. The old mastic is removed and the joint resealed with a flexible exterior sealant. If you have water coming in at the bottom corners of a door and white mastic on grey or black frames, we can put it right, whatever the surface.
Mastic can only go onto a dry joint, so outside work in Newtonmore depends on the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
Each job carries a 12-month guarantee.

What the job involves on each surface
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A neat, narrow bead in a colour to match keeps the clean look.
Window sills
Masonry sills can have joints where water gets in, including the one between the sill and the frame above. We seal those with a sealant suited to masonry.

Why act early in Newtonmore
A quick bead over the top of old mastic looks like an easy fix, but it will not grip old, dirty sealant. It soon lifts and the leak carries on behind it. Proper resealing starts with removing the old joint. Around Newtonmore, water from a failed joint in an older stone home can soak into timber and plaster.
A failed joint rarely gets cheaper to fix by waiting. If you are not sure whether it needs doing, email us at info@mrmastic.co.uk for an honest opinion and a quote.

What window mastic looks like in Newtonmore
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. The west of Scotland is wetter than the east, so there’s plenty of rain for the mastic around window and door frames to keep out.
Letting a property close to Newtonmore station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. In and around Newtonmore, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

The process
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a handful of frames, longer for a whole house, and the area is left clean. Outside jobs in Newtonmore need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We check how each frame can be reached safely.
- All the failed sealant is cut away.
- The surfaces are cleaned and left dry.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Move anything stored near the joints
- Tell us about any water getting in
