Window Mastic in Lambhill
We cover Lambhill for mastic around window and door frames, sills and patio doors. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Leaking joints at the ends of sills
- Draughts coming in around windows and doors
- Cracked or shrunken mastic around the frame
About our window mastic in Lambhill
If you can feel air around a shut window, the gap is often at the frame. Resealing that joint can make a room feel noticeably less draughty. If the draught is through the window seals instead, we will tell you. We work on aluminium frames, composite doors and patio & French doors, and people most often call us about gaps where the sill meets the wall and mastic that’s falling out in pieces.
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.
The work is covered for a year after we finish. If there’s a problem with it, please drop us a line at info@mrmastic.co.uk.

Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Do not paint over the silicone
- Don’t use solvent cleaners on the joint
- Keep paint and stain on wooden frames in good order
- Keep jet washers away from the mastic
Check the drainage slots in the frames aren’t blocked, so water can run away instead of sitting against the joint.
Wet, windy weather is when failed mastic shows itself, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.

What else we do in Lambhill
Window mastic in Lambhill: local notes
Much of Glasgow is built from red and blond sandstone, and porous sandstone needs a sealant that will not mark it. With historic houses such as Tenement House (about 1.7 miles south) nearby, there’s older building stock in the area around Lambhill as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
For site and facilities teams at buildings such as John Paul Academy, its window and door frames need their mastic kept sound, just like a home’s. If you let a flat or house near Possilpark & Parkhouse station, renewing tired window mastic between tenants heads off draught and damp complaints.

How we quote for window mastic
The quote reflects the job in front of us. We look at:
- The type of sealant required
- Any mould that needs treating
- The old material and how stubborn it is
- How many rooms, windows or areas are involved
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts.
What to tell us for a quote
You don’t need to know the technical terms. It helps if you can tell us:
- If it’s domestic, commercial or a hotel
- Where the job is, and your postcode
- What’s wrong with the joints now
- Roughly how big the job is
If you are in Lambhill and need window mastic, email us at info@mrmastic.co.uk. Tell us what the problem is and where, and we’ll agree the price before any work begins.
What happens on the day
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it usually takes anything from an hour or two to a full day, depending on how many frames there are. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. In Lambhill, it helps to know the floor, the door entry arrangements and the nearest parking.
- 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.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- For business premises, tell us about site rules or sign-in
- Clear the area around the work
How to get a quote

What we’re called out for in Lambhill
Joints that are too thin or too deep fail early. A thin smear across a wide gap has nothing to it, and a gap filled solid can’t flex. That is what backing rod is for.
The problems people usually mention when they call include:
- Cracked sealant at the sill ends
- Draughts coming in around windows and doors
- A bead that does not match the frame
- Gaps between the frame and the inside reveal
Tenement House, about 1.7 miles south, is one of the historic houses in the wider area around Lambhill.
Questions to ask before booking
- Is the old sealant removed completely?
- How the joint is cleaned and prepared
- What guarantee comes with the work
- How much experience the applicator has
How the job changes by surface
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. We will point out any rot we find, as that’s a job for a joiner.
Composite doors
Front doors take the weather head on. We pay most attention there.
When something else is needed
In fairness, there are a few things sealant won’t fix:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- A frame that has rotted at the joint
- Broken hinges, locks or handles
Not sure which it is? You can send an email to info@mrmastic.co.uk and we will tell you honestly.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
