Window mastic in Dowanhill, done properly
Frames and walls do not move together. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. If you’re dealing with gaps where the sill meets the wall and damp patches on the reveal after heavy rain, we can put it right, whatever the surface.
Tenement flats in Scotland’s cities often have windows high above the street, so the mastic outside can go unchecked for years. For a flat in Dowanhill, access is the first thing to plan.
All of our work is guaranteed for twelve months.

Common questions in Dowanhill
How is work on the outside of a tenement in Dowanhill usually arranged?
It generally goes through the owners together, or through the factor if the building has one. The Tenements (Scotland) Act 2004 covers the common parts where the deeds don’t.
Can you do window mastic in Dowanhill?
Yes, Dowanhill is within the area we cover. Our work covers the whole of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Do you have insurance?
Yes. Full insurance covers our work.
When is the sealant fully cured?
Different products cure at different speeds, so please follow the time we give you when we finish.
Is it messy?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we’re done.
How do I get a quote for window mastic in Dowanhill?
Size, access and the old material all affect the cost. Call for a quick quote and we will talk you through it.
Do you seal inside as well as outside?
Yes. Plenty of draughts come through the inside joint as well as the outside, so it can be worth sealing both.
Can tenants book the work?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.

How the visit works
We keep the work tidy and contained to the area we’re working on, so you can carry on as normal. Expect the work to take a few hours for a few frames, or a day or more for a whole house, and we tell you how long to leave it before we go. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. For a job in Dowanhill, tell us the floor, how the door entry system works and where we can park nearby.
- 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.
- The joint is shaped to shed water and the area tidied.
How to prepare
- Clear the area around the work
- Plan for the work area to be out of bounds to pets and children
- Where the joints are inside, avoid wetting them before we arrive
How to get a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.

DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
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.

When something else is needed
A few problems are outside what sealant work can do:
- Condensation trapped between the panes
- Penetrating damp from a failed cavity tray or render
- Draughts through the window seals rather than the frame
If in doubt, email us at info@mrmastic.co.uk and we will say what we think.
Surfaces we seal
- Patio & French doors
- uPVC windows
- Composite doors
- Timber windows & doors
- Window sills
- Aluminium frames
What we are called out for in Dowanhill
Frames are never completely still. Sun on a frame makes it expand, and it contracts again overnight, while the brick or render around it hardly moves. If the sealant can’t stretch, it splits.
Look out for these signs:
- Black, perished sealant on frames
- Rain getting in at the frame or under the sill
- Rushed sealant from a window installation
- Draughty joints inside around the window
Tenement House, about 1.4 miles south-east, is one of the historic houses in the wider area around Dowanhill.

Surface by surface
Window sills
Sills catch the water running down the glass, so the joints at each end and underneath matter. Each is cleaned out and resealed.
Aluminium frames
Aluminium needs a sealant that bonds to coated metal and we avoid acetoxy silicones, which can react with some metals. We use a neutral-cure product.
