Joints and finishes in Dennistoun homes
Many new homes in Scotland are timber-framed, and as the frame dries and settles, skirting and sealant joints can open up. The west of Scotland is wetter than the east, which means plot mastic and the sealant in new homes has to cope with a lot of rain.
In and around Dennistoun, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

New build mastic in Dennistoun
A new house keeps drying out and settling for its first couple of years. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. We’re often asked to deal with new-build shower sealant that has already split and smeared, uneven beads picked up at snagging, on show homes, windows & doors and kitchens.
New flats and houses are still being built in and around Scotland’s cities, and new-home owners often find sealant snags in the first year or two.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

Questions from Dennistoun
I let a flat near Duke Street 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 send you a clear quote.
Is Dennistoun in your area for new build mastic?
Yes. We work across all of Scotland, and Dennistoun 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 give you a clear price.
Do I have to be there?
It depends on the job. Inside work needs someone to give us access.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Who should fix failed sealant in a new build?
Start with your builder while their snagging or warranty period runs. If that doesn’t work out, we are happy to quote with our one-year guarantee.
Can I send you my snagging list?
Yes. Send us the sealant items on the list, with photos if you can, and we will quote. We will tell you if anything on it isn’t a sealant job.
Are you fully insured?
Yes. We’re fully insured, with over 20 years’ experience in sealant work.
Can you do plot mastic on a new development?
Yes. We work through plots to your schedule ready for handover. Tell us the plots and the joints involved and we’ll quote.
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Wipe joints with warm soapy water
- Put sealant faults on your snagging list early
- Follow the cure time we give you
- Keep photos and emails about snagging items
Avoid standing on the rim of the bath or the edge of the tray. 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. Early resealing keeps the job small and the new finishes intact.
What we cannot put right
We’ll always be straight with you, so here’s what sealant can’t fix:
- Settlement cracks that need a surveyor
- Cracked trays, tiles or worktops
- Plumbing faults behind the sealant
If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think.
Joints and surfaces we work on
- Skirting & floors
- Plot handovers
- Windows & doors
- Kitchens
- Show homes
- Bathrooms & en suites
How it works
Once we are on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours in a single home. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. In Dennistoun, it helps to know the floor, the door entry arrangements and the nearest parking.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
How to prepare
- Let us know about earlier repairs to the joints
- Mention any leaks or damp you’ve noticed
- Tell us if parking is tricky

- Cracked sealant around new window and door frames
- Shower seals failing in the first year or two
- Skirting joints opening in the first winter
- Gaps behind new kitchen upstands
If you’ve bought a new home near Duke Street station, the sealant around baths, showers and frames is worth checking in the first year or two.

- How much old sealant there is and how hard it is to remove
- The type of sealant required

Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
What we need to know
When you call or email, these details help:
- What the problem is, such as mould, gaps, leaks or cracking
- How we’d reach the joints
- Where the property is
- If someone has resealed it before
