About our new build mastic in Canongate
Developers send us the plot schedule and we work through it. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over with a sealant suited to each area. We’re often asked to deal with smeared, uneven beads picked up at snagging and gaps behind new kitchen upstands, across show homes, plot handovers and windows & doors.
Offices, shops and commercial units in Scotland’s cities have floors with movement joints and thresholds that take heavy wear. In Canongate, we cover those floor joints as well as plot mastic for developers.
Your job is guaranteed for a year, as with all our work.

What happens if it’s left?
DIY kits do not solve the main problems with new-build sealant: dust, no primer and old sealant left in the joint. Proper removal and preparation are what make it last. Wind-driven rain gets into any failed joint on the outside of a city building, and in a tall building in Canongate, damp can travel a long way before it shows.
What it costs depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts.

Joints and finishes in Canongate homes
Canongate 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.
Around Canongate, as everywhere, new build mastic is only as good as the preparation behind it.

Keeping the joints in good condition
After the cure time, these simple habits help:
- Act quickly if a seal starts to leak
- Resist patching a failed seal with a tube from the DIY shop
- Record problems with dated photos
- Watch for new gaps as the house dries out
Leave the sealant for the cure time we give you before showering or bathing. Silicone is generally left for about a day to cure enough for use.
Do not let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you, so raise it early.
Your questions about new build mastic in Canongate
Can you do new build mastic in Canongate?
Yes. Our work covers the whole of Scotland, and Canongate is part of that. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing, and we’ll send you a clear quote.
I let a flat near Edinburgh Waverley station. Can you help?
Yes, we work for landlords and letting agents. Just drop us a line at info@mrmastic.co.uk and tell us about the property, and we’ll give you a clear quote.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Will you leave a mess?
We keep the work tidy. Nearby surfaces are protected.
Why does sealant fail so quickly in new builds?
There are generally two causes: movement as the house dries and settles, and sealant laid onto dust without primer. A proper reseal deals with both.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status, and we’re fully insured.
How long should I leave it?
Different products cure at different speeds, so please follow the time we give you when we finish.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned.
What affects the cost of new build mastic
You will get a clear quote before any work starts. It takes into account:
- The old material and how stubborn it is
- The size of the job
- Working hours on commercial sites
- The product the joint needs
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, email us at info@mrmastic.co.uk for an honest opinion and a quote.
What to tell us for a quote
When you contact us, these details help:
- Pictures of the joints, sent by email
- If someone has resealed it before
- Whether it’s a home or a business
- How many joints, rooms or windows are involved
For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we’ll talk you through the work.
What happens on the day
When we arrive, we start by going over the job with you. Surfaces next to the work are protected before any work begins. Most jobs take a few hours for most snagging lists, longer for a run of plots. For a tenement in Canongate, work inside your flat is between us and you, while shared parts may need the factor or neighbours to agree. It helps to know which it is when you get in touch.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- The old bead comes out in full, with no layer left behind.
- Surfaces are cleaned of building dust and primed where needed.
- New sealant suited to each joint is applied and tooled neatly.
- Each area is checked and left with its cure time.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Clear the area around the work
- Mention any tricky access
Ask for a quote
Getting a quote is simple: let us know the job and the location, and roughly how big it is. A few pictures by email make the job easier to understand.
Advice
DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
What we’re called out for in Canongate
On many sites, sealant goes on in the final rush before handover. Dusty, unprimed joints are common, and the sealant sits on grit instead of the surface.
Most people get in touch when they notice one of these:
- Cracked sealant around new window and door frames
- Shower seals failing in the first year or two
- Beads laid onto grit and dust from the build
- Gaps opening as the house dries out and 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.
What your quote should include
- Is the old sealant removed completely?
- The length of the guarantee
- How much experience the applicator has
- What preparation is included
