Window mastic in Gartly
The mastic around a window or door seals the gap between the frame and the wall. When it cracks, hardens or pulls away, draughts and rain get in. The old mastic is removed and the joint resealed with a flexible exterior sealant. Common call-outs are for white mastic on grey or black frames and rain getting in at the frame or under the sill, on window sills, patio & French doors and timber windows & doors.
In and around a place like Gartly, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

How the visit works
At the end, we look at the finished work together. The work normally takes a few hours for a handful of frames, longer for a whole house, depending on the size of the job. Somewhere like Gartly may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- 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.
- We tool each bead neatly and check every joint is closed.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Tell us about any previous sealing or DIY attempts
- Keep pets and children clear of the area while we work

Common questions in Gartly
Is Gartly within the area you cover?
Yes, Gartly is covered. We work across all of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
I let a flat near Huntly station. Can you help?
Yes, rental work is part of what we do. You can send an email to info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before work begins.
Is it OK to seal over old sealant?
No, because it fails. The old sealant always comes out first.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Can you do the inside joint as well?
Yes, we do both. Inside, the joint between frame and plaster is sealed neatly.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
What does window mastic cost?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before we start.
Do you work on first-floor windows?
Yes, as long as they can be reached safely. Tell us about access when you get in touch and we’ll plan for it.
Do you need window mastic in Gartly?
Water runs down the glass onto the sill, so the sill ends and the joint below the frame are common leak points. Failed sealant there lets rain into the wall or behind the frame.
People usually contact us when they notice something like this:
- Damp patches on the reveal after heavy rain
- Rushed sealant from a window installation
- Hard, cracked sealant around windows
- Sealant in the wrong colour for the frame
Leith Hall, about 2 miles south-east, is one of the historic houses in the wider area around Gartly, and older homes nearby need a sealant that suits their walls.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
What window mastic looks like in Gartly
With historic houses such as Leith Hall (about 2 miles south-east) nearby, there’s older building stock in the area around Gartly 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. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
If you let a flat or house near Huntly station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Why it’s worth doing now in Gartly
Failed mastic is not a reason to replace sound windows. Where the frames are sound, new mastic generally deals with draughts and leaks at the edges. If we find failed glass units or worn seals, we’ll tell you. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

Different surfaces, different methods
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. We will point out any rot we find, as that is a job for a joiner.
uPVC windows
We clean the frame edge carefully so the plastic is not marked, then the sealant goes in between frame and wall.
Aftercare tips
A little care helps the new joints last. We recommend:
- Keep solvents and bleach off the sealant
- Walk round the house once a year and look at the joints
- Don’t aim a pressure washer at the joints
- Wipe condensation off the frames
A yearly look round the frames is enough. Small splits are simple to catch before they leak, and if anything looks wrong, just send an email to info@mrmastic.co.uk.
Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
