About our new build mastic in Dowanhill
Some owners wait for the first year’s movement before having joints redone. That makes sense for small gaps that are just cosmetic, but a failed shower or bath seal shouldn’t wait. If you have cracks appearing as a new home settles and leaking shower tray seals in a new home, we can put it right.
Offices, shops and commercial units in Scotland’s cities have floors with movement joints and thresholds that take heavy wear. Those joints, and plot mastic for developers, are part of the work we cover in Dowanhill.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

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 in a single home, and we explain the cure time before we leave. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. In Dowanhill, it helps to know the floor, the door entry arrangements and the nearest parking.
- Each joint is checked for movement before work begins.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
Before we arrive

- Mention any sign-in or site rules at work premises

Advice
What new build mastic looks like in Dowanhill
The west of Scotland is wetter than the east, which means plot mastic and the sealant in new homes has to cope with a lot of rain. Many new homes in Scotland are timber-framed, and as the frame dries and settles, skirting and sealant joints can open up.
For new homes near Hyndland station, it’s worth checking the sealant early, while snags are still fresh.

Questions from Dowanhill
I let a flat near Hyndland station. Can you help?
Yes, landlords and agents are among the people we work for. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we’ll send you a clear quote.
Is new build mastic in Dowanhill guaranteed?
All our work, in Dowanhill and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
What does new build mastic cost?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You will get a clear quote before work begins.
When is the best time to reseal in a new build?
Any seal that’s leaking should be redone straight away. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
Do you use white or clear sealant?
The colour is chosen to suit the tiles, worktop or frame. Let us know your preference when you ask for a quote.
Can you work from my snagging list?
Yes. Snagging lists are a common starting point for us. We agree the sealant items with you before we start.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.
What sealant 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 tell you what we’re using.
When to call us in Dowanhill
The first winter with the heating on dries a new home quickly. Skirting, frames and worktops pull away slightly and cracked sealant shows up.
These are the problems we’re asked about most:
- Skirting joints opening in the first winter
- Internal frame sealant that has split
- Shower seals failing in the first year or two
- Second-fix sealing on new plots
In and around Dowanhill, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Why act early in Dowanhill
If you are still in the builder’s snagging or warranty period, ask them to put it right first. If it keeps failing or is not dealt with, we can reseal it properly. For landlords in Dowanhill, damp and leaks can be a Repairing Standard issue, so failed sealant is best replaced before it becomes a complaint.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts.
What you get with us
- You choose the colour before work begins
- Any old sealant cut out fully, not covered over
- ARBOMaster approved applicator
- Every job guaranteed for a year
Aftercare tips
To keep the joints looking good and working properly:
- Keep water off fresh sealant until it has cured
- Check bath and shower seals every few months as the house settles
- Open a window or run the fan after bathing
- Do not seal over failed sealant yourself
Keep pictures of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.
Early snagging is easier snagging. Left alone, a small crack can become a leak in a busy bathroom.
DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
When something else is needed
Sealant is not the answer to every problem, and we’d rather say so up front. It will not solve:
- Leaks from pipes, valves or wastes, which need a plumber
- Cracked trays, tiles or worktops
- Settlement cracks that need a surveyor
Not sure which it is? You can send an email to info@mrmastic.co.uk and we will tell you honestly.
