About our new build mastic in Leith
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. In both, preparation makes the difference. We work on skirting & floors, bathrooms & en suites and windows & doors, and common reasons people get in touch are kitchen sealant that has pulled off the wall and sealant work across a run of new homes.
In older Scottish city flats, floors are often timber over joists, with skirting joints that open and close with the seasons. In Leith, a flexible sealant suits those joints better than filler.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

What happens on the day
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from a few hours to several days, depending on the number of plots. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. For a job in Leith, tell us the floor, how the door entry system works and where we can park nearby.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Keep pets and children clear of the area while we work
- Tell us if parking is tricky

Your questions about new build mastic in Leith
Do you work for landlords with property near Edinburgh Waverley station?
Yes, rental work is part of what we do. You can drop us a line at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before we start.
Can you do new build mastic in Leith?
Yes, Leith is within the area we cover. We work across all of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job.
Will there be a smell?

Can you do plot mastic on a new development?
Yes. We work through plots to your schedule. Tell us the plots and the joints involved for a clear quote.
Do you take out the old sealant first?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.

Yes. We have worked for hotels, offices and other businesses.
Will you leave a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Do you work through snagging lists?

What we cannot put right
New sealant can’t fix everything, and we will tell you before we start. Sealant will not put right:
- Plumbing faults behind the sealant
- Damaged fittings that need replacing
- Baths and trays that move too much for sealant to cope with
If you’re not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer before booking.
Surfaces we seal
- Show homes
- Skirting & floors
- Kitchens
- Bathrooms & en suites
- Windows & doors
- Plot handovers
What happens if it’s left?
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Resealing promptly protects the new finishes around it. In a tenement flat in Leith, a failed seal is rarely just your problem: a leak can come through the ceiling below, and gaps in shared walls or fire-rated joints matter to every flat.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
What you get with us
- We’re fully insured
- Every job guaranteed for a year
- You choose the colour before work begins
- We never seal over old sealant

New homes and floors in Leith
Leith is within about 1 mile of the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. Timber frame is common in newer Scottish homes, so skirting and sealant joints can open up as the building settles.
If you’ve bought a new home near Edinburgh Waverley station, the sealant around baths, showers and frames is worth checking in the first year or two.

Looking after it afterwards
Aftercare is simple:
- Look at the sealant regularly in the first couple of years
- Avoid running a DIY bead over the old one
- Report sealant problems to your builder during the snagging period
- Open a window or run the fan after bathing
Don’t stand on the bath edge or the lip of the tray in the first few weeks. If a bath or tray moves when you stand in it, get it looked at.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant.
Do you need new build mastic in Leith?
Later trades and the final clean can damage fresh sealant. A bead disturbed before it has cured may never seal properly and it shows once the home is in use.
Any of these means the joints need attention:
- Internal frame sealant that has split
- Beads laid onto grit and dust from the build
- Worktop and upstand sealant coming away
- Smeared, uneven beads picked up at snagging
In and around Leith, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
What to look for in a quote
- How much experience the applicator has
- Which colour the sealant will be
- How the joint is cleaned and prepared
- What the quote includes, VAT included or not
Can I do it myself?
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, then guaranteed for a year.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
