Kelvinhaugh Window Mastic
Our applicators work in Kelvinhaugh on mastic around window and door frames, sills and patio doors. Old sealant removed completely, joints prepared properly.
- Mastic that has split away from the wall
- Leaking joints at the ends of sills
- Old mastic that has gone black or come away
What happens on the day
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. It normally takes a morning for a couple of windows and a door. For a tenement in Kelvinhaugh, 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.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about earlier repairs to the joints
- Keep pets and children clear of the area while we work

About our window mastic in Kelvinhaugh
Over two decades of sealing frames has taught us which products suit which walls. We’re ARBOMaster approved and fully insured, and every job is covered by a 12-month guarantee. We work on aluminium frames, window sills and uPVC windows, and the jobs we see most are cracked internal joints between frame and plaster and a bead that doesn’t match the frame.
Kelvinhaugh is in one of Scotland’s four big cities, where many older buildings are sandstone or granite. Stone needs a sealant that suits it, so acetoxy silicones, which can attack some stone, are best avoided.

Surface by surface
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so the joint needs a low-modulus sealant that stays flexible. We match white, brown, anthracite grey and black frames.
Window sills
Sills catch the water running down the glass, so the sill ends and the joint under the frame are vital. Each is cleaned out and resealed.

When to call us in Kelvinhaugh
A lot of older mastic was never designed to stay flexible. Once it’s rigid, every bit of frame movement pulls at it, and a gap opens along one edge.
These are the problems we are asked about most:
- Cracked or shrunken mastic around the frame
- Draughty joints inside around the window
- Gaps where the sill meets the wall
- Untidy mastic left by window fitters
Managing a site like Church Street Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.
Questions to ask before booking
- Is the old sealant removed completely?
- How the colour is chosen
- What happens if the job turns out different
- What product goes in the joint
Looking after it afterwards
So the new joints stay in good condition:
- Walk round the house once a year and look at the joints
- Repaint timber before it’s bare
- Ventilate rooms so frames do not stay wet inside
- Keep solvents and bleach off the sealant
On timber frames, keep the paintwork in good order, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.
Water gets in quietly when mastic fails. You might not see it until plaster blows or a damp patch appears inside. Early resealing stops it reaching that point.
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
What affects the quote in Kelvinhaugh
We don’t publish a price list, because jobs vary so much. What we look at:
- Whether the work is at height
- The number and length of the joints
- The old material and how stubborn it is
- Working hours on commercial sites
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, email us at info@mrmastic.co.uk and we will give you an honest view and a quote.

Common questions in Kelvinhaugh
Do you cover Kelvinhaugh for window mastic?
Yes. We work across all of Scotland, and Kelvinhaugh is part of that. You can email us at info@mrmastic.co.uk and let us know what needs doing.
Who arranges sealant work on the shared parts of a tenement in Kelvinhaugh?

Can you do upstairs windows?
Yes, in most cases. We plan safe access before the job.
Can new window sealant be painted?
It depends on the sealant. Some hybrid sealants can be painted; silicone can’t. Tell us if you’re decorating and we will choose accordingly.
Does the work come with a guarantee?
Yes, with our one-year guarantee. A yearly look at the joints helps them last.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
Can tenants book the work?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
Frames and glazing around Kelvinhaugh
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that. Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
If you live in an older home near Sandyford Henderson Memorial Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Rented homes near Exhibition Centre station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
