New build mastic for homes and businesses in Coltness
Some new-home owners let the house settle before resealing. For small cosmetic gaps, that’s reasonable, but a failed shower or bath seal shouldn’t wait. We work on show homes, bathrooms & en suites and skirting & floors, and the jobs we see most are joints pulling apart as timber shrinks and gaps behind new kitchen upstands.
Around smaller Scottish places like Coltness, new homes tend to be single plots or small developments. Each needs its sealant and floor joints finished as carefully as on a big site.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Questions from Coltness
Do you cover smaller places like Coltness?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Do you work for landlords with property near Cleland station?
Yes, we work for landlords and letting agents. You can drop us a line at info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before any work starts.
Can I do it myself?
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.
Do you guarantee your work?
Yes. Each job is guaranteed for twelve months, wherever you are.
How long does the job take?
Most jobs take anything from a few hours to several days, depending on the number of plots. Your quote will say how long we expect yours to take.
Can you work from my snagging list?
Yes. Photos of each sealant item help us quote. If something is not sealant, we will say so.
Do you take out the old sealant first?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Should I wait before resealing?
For failed seals that let water through, the best time is now. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
Honest limits
New sealant can’t fix everything, and we’d rather say so up front. Sealant won’t put right:
- Cracked trays, tiles or worktops
- Cracking that points to a structural problem
- Movement caused by a poorly fitted tray or bath
If in doubt, email us at info@mrmastic.co.uk and we will say what we think.

Should I try it myself first?
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.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
What affects the quote in Coltness
The price is agreed before any work begins. It’s based on:
- Any mould that needs treating
- Working hours on commercial sites
- The number of rooms or windows
- How easy the joints are to reach
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
Helping us quote
When you contact us, it’s useful to know:
- The address or postcode of the job
- The type of property
- What’s wrong with the joints now
- How we’d reach the joints
Asking for a quote is easy: let us know what needs doing and where, and roughly how big it is. Photos by email help us understand the job, and we’ll take it from there.
Common problems we fix in Coltness
Baths and trays settle under load once the home is lived in. A bath sealed empty drops slightly when filled, straining the joint and can tear.
Keep an eye out for any of the following:
- New-build shower sealant that has already split
- Frame joints opening as the plaster dries
- Sealant work across a run of new homes
- Cracks appearing as a new home settles
If you’ve bought a new home near Cleland station, the sealant around baths, showers and frames is worth checking in the first year or two.

Advice
How the job changes by surface
Windows and doors
On new builds, external frame sealant can be patchy. It’s resealed with an exterior sealant suited to the frame and wall.
Plot handovers
We work through plots to your schedule, sealing each room ready for handover. Each joint is cleaned and primed where needed so the sealant lasts.
Landlords, agents and businesses in Coltness
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
