New build mastic in Merchiston, done properly
In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water gets into the floor or walls. We work on skirting & floors, show homes and plot handovers, and the jobs we see most are cracked caulk along new skirting and kitchen sealant that has pulled off the wall.
In a Scottish city, commercial floors have movement joints and thresholds that wear under traffic. In Merchiston, we cover those floor joints as well as plot mastic for developers.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Look at the sealant regularly in the first couple of years
- Raise failed sealant with the developer while you are covered
- Avoid running a DIY bead over the old one
- Follow the cure time we give you
Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry and can be resealed later.
Do not let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you.
New homes and floors in Merchiston
Merchiston is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. Many new homes in Scotland are timber-framed, and as the frame dries and settles, skirting and sealant joints can open up.
In and around Merchiston, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. If you’ve bought a new home near Haymarket station, the sealant around baths, showers and frames is worth checking in the first year or two.

Merchiston: your questions answered
What guarantee comes with new build mastic in Merchiston?
Every job comes with our one-year guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
I let a flat near Haymarket station. Can you help?
Yes, rental work is part of what we do. Just drop us a line at info@mrmastic.co.uk and tell us about the property, and we’ll give you a clear price.
Are you ARBOMaster approved?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
What do you put in the joint?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
Can you do plot mastic on a new development?
Yes. We seal plots to the developer’s programme. Tell us the plots and the joints involved for a clear quote.
How much does new build mastic cost in Merchiston?
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 we start.
Do you use white or clear sealant?
It depends on the joint: white or clear for most sanitary joints, colours for worktops, floors and frames. We agree the colour before work begins.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done and we will quote it together.
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
If you’ve already had a go yourself, that is fine. We cut it out and start again.
What sealant work can’t fix
We will not take on work that will not last, so here’s what sealant cannot put right:
- Leaks from pipes, valves or wastes, which need a plumber
- Baths and trays that move too much for sealant to cope with
- Cracking that points to a structural problem
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly.
Surfaces we seal

The process
Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for most snagging lists, longer for a run of plots. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. For a job in Merchiston, tell us the floor, how the door entry system works and where we can park nearby.
- 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.
Getting ready for the visit
- Clear the area around the work
- For indoor joints, keep the area dry beforehand if you can
- Keep children and pets away from the work area
