Common questions in Edinburgh
I let a flat near Haymarket station. Can you help?
Yes, landlords and agents are among the people we work for. You can email us at info@mrmastic.co.uk with the details for a clear quote.
Can you do new build mastic in Edinburgh?
Yes. We work across all of Scotland, and Edinburgh is part of that. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing.
Is it normal for sealant to crack in a new home?
It’s common, and there are usually two reasons: movement as the house dries and settles, and sealant laid onto dust without primer. A proper reseal deals with both.
Is the work guaranteed?
Yes, always. There’s a 12-month guarantee on every job, wherever you are.
Do you have insurance?
Yes. We are fully insured, and we can confirm the details when we quote.
How long should I leave it?
Different products cure at different speeds, so please follow the time we give you.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.
New build mastic in Edinburgh
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. Both get the same care over preparation, because that’s what rushed new-build sealant usually lacks. We work on kitchens, show homes and windows & doors, and the jobs we see most are gaps behind new kitchen upstands and skirting joints opening in the first winter.
New flats and houses are still being built in and around Scotland’s cities, and in new homes, sealant and floor joints are often among the first snags, in Edinburgh as anywhere.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.
Why deal with it now?
A quick bead over the top of the old sealant can look fine at first, but it will not bond to the old layer. A lasting seal starts with removing the old one completely. In a Scottish city tenement, failed sealant affects more than one flat: a leak can come through the ceiling below, and gaps in shared walls or fire-rated joints matter to every flat.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first.
What you get with us
- Old sealant always removed completely
- Fully insured
- Homes, businesses and hotels
- Anti-fungal sanitary silicone in wet areas

Honest limits
To be straight with you, some problems need a different trade:
- Structural cracks in walls or ceilings
- Broken tiles or a split tray
- Leaks from pipes, valves or wastes, which need a plumber
If you’re not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer before you book.
Joints and surfaces we work on
- Plot handovers
- Kitchens
- Bathrooms & en suites
- Skirting & floors
- Show homes
- Windows & doors
Different surfaces, different methods
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
Skirting and floors
New homes often develop a gap between skirting and floor. We seal it with a flexible sealant that copes with the movement.
New build mastic in Edinburgh: local notes
Edinburgh is close to the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles.
In and around Edinburgh, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
We also work for property managers and facilities teams. Several sites can be quoted together, and we are fully insured.
How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Record problems with dated photos
- Open a window or run the fan after bathing
- Check bath and shower seals every few months as the house settles
- Get a leaking seal dealt with right away
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day to cure enough for use.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant and protects the rest of the house.
What we are called out for in Edinburgh
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.
If you can see any of these, it’s time to have the joints looked at:
- Sealant applied over dusty or wet surfaces
- Gaps opening as the house dries out and settles
- Cracked caulk along new skirting
- Smeared, uneven beads picked up at snagging
For new homes near Haymarket station, it’s worth checking the sealant early, while snags are still fresh.
What to look for in a quote
- What the cure time is

What we do, step by step
When we arrive, we look over the joints with you first. Surfaces next to the work are protected before work begins. Most jobs take a few hours in a single home. Parking in city streets around Edinburgh can be tight or controlled, so it helps to know about permits or nearby bays. For flats, mention the door entry system and any shared-stair arrangements.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- Tell us about access, such as stairs, a lift or high-level joints
- Clear items away from the joints we’re working on
