Window mastic in Kelvinbridge
The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. Our applicators cut it out and replace it with a flexible, weatherproof sealant. We work on composite doors, window sills and uPVC windows, and the jobs we see most are rushed sealant from a window installation and white mastic on grey or black frames.
Scotland’s cities are full of stone-built tenements and terraces, in sandstone or granite. Stone needs a sealant that suits it, which generally means a neutral-cure product or a traditional sand mastic rather than an acetoxy silicone.
Each job carries a 12-month guarantee, whatever its size.

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Ventilate rooms so frames don’t stay wet inside
- Look round the frames every year or so
- Avoid blasting the frames with a pressure washer
- Do not use solvent cleaners on the joint
Wipe the frames with soapy water when you clean the windows, and avoid solvent cleaners on the sealant.
Signs to watch for: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. If you notice one, it’s time to get the joint looked at.
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
What window mastic looks like in Kelvinbridge
Much of Glasgow is built from red and blond sandstone, and sandstone is porous, so any sealant against it has to be one that won’t stain or attack it. Kelvinbridge is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for the mastic around window and door frames to keep out.
For an older house near a landmark such as St Vincent Street Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For site and facilities teams at buildings such as College of Piping, the mastic around its windows and doors needs looking after like any other building’s. For landlords with property near Charing Cross (Glasgow) station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Why deal with it now?
A quick bead over the top of old mastic looks like an easy fix, but new sealant cannot bond to old, crumbling mastic. It peels before long, and water still gets in behind. The old mastic has to come out. Private landlords in Kelvinbridge must meet the Repairing Standard, and damp or leaks can fall short of it, so it’s worth fixing failed sealant before a tenant reports it.
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, send an email to info@mrmastic.co.uk for an honest opinion and a quote.

How it works
Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes anything from an hour or two to a full day, depending on how many frames there are. For a tenement in Kelvinbridge, work inside your flat is between us and you, while shared parts may need the factor or neighbours to agree. Tell us which applies when you book.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away, along with any loose debris.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Let us know about parking restrictions
- Let us know about stairs, lifts or work at height

How the job changes by surface
Patio & French doors
Door frames take knocks and movement every time the doors are used. The sealant must cope with it, where a rigid one would crack.
Window sills
The end joints of a sill tend to fail before the rest. We reseal them so rain can’t run into the wall.
What we can’t put right
To be straight with you, some problems need a different trade:
- Draughts through the window seals rather than the frame
- A failed sealed unit that has misted up
- Damp problems in the wall away from the window
If you are not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer before you book.
