New build mastic for homes and businesses in Kingarth
Some owners wait for the first year’s movement before having joints redone. That makes sense for small gaps that are just cosmetic, but a failed shower or bath seal shouldn’t wait. We work on kitchens, skirting & floors and show homes, and common reasons people get in touch are joints pulling apart as timber shrinks and leaking shower tray seals in a new home.
Work in a place like Kingarth is planned ahead, journey included. Outdoor plot mastic needs dry weather, but indoor floor and skirting joints can be sealed whatever the forecast.
The work is covered for a year after we finish. If there’s a problem with it, please send an email to info@mrmastic.co.uk.

What else we do in Kingarth
What happens on the day
Every visit runs the same way: we check the joints, protect the area around them, do the work and tidy away. It normally takes a few hours for most snagging lists, longer for a run of plots. Outside jobs in Kingarth need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- Each joint is checked for movement before any work starts.
- 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.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Where the joints are inside, avoid wetting them before we arrive
- Tell us if parking is tricky

- 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
For jobs in and around Kingarth, choosing the right material for each joint is as important as a tidy finish.

New build mastic in Kingarth: local notes
Kingarth 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. Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up.
In and around Kingarth, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Kingarth is about 13 miles north-west of Saltcoats, in Argyll and Bute. We provide new build mastic to homeowners, landlords and businesses in Kingarth and nearby. Kingarth is one of 118 places in Argyll and Bute where we work for new build mastic. Glasgow is on our list too, about 30 miles from Kingarth.

Different surfaces, different methods
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We cut out the cracked bead and reseal with a flexible sealant that suits the frame.
Plot handovers
Send us the schedule and any sealant specification. We seal bathrooms, kitchens, frames and floors to the agreed spec.
Leave it or put it right?
DIY kits don’t 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. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.

Common questions in Kingarth
Do you cover smaller places like Kingarth?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Can you do new build mastic in Kingarth?
Yes, Kingarth is within the area we cover. Our work covers the whole of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job.
When is the sealant fully cured?
Different products cure at different speeds, so please follow the time we give you when we finish.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Do you guarantee your work?
Yes, always. There’s a 12-month guarantee on every job, large or small.
Why does sealant fail so quickly in new builds?
It’s common, and there are normally two reasons: the house moving as it dries, and sealant that never bonded properly. A proper reseal deals with both.
Can I add another job to the visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
Do you do commercial work?
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.
DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Use the extractor fan every time you shower
- Put sealant faults on your snagging list early
- Record problems with dated pictures
- Wait for the cure time before using a resealed shower
Keep pictures of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.
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.
