- Gaps behind new kitchen upstands
Surface by surface
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. The joint is stripped back before the new bead goes in with baths filled first.
Kitchens
As a new house dries, worktops and walls shift a little, opening gaps behind the upstand. A fresh flexible bead closes them.
How we handle new build mastic in Dalserf
We work in new homes and on new-build sites across Dalserf. Whether it’s one en suite or a run of plots, the method is the same: remove, clean, prime where needed, then a neat new bead. We work on plot handovers, show homes and windows & doors, and the jobs we see most are cracked caulk along new skirting and messy sealant that spoils new finishes.
Many newer homes in Scotland are timber-framed and settle as they dry out, so skirting and floor joints can open up. In older homes, timber floors move through the year too.
A one-year guarantee comes as standard, so you are covered after we have gone.

Dalserf: your questions answered
Do you cover Dalserf for new build mastic?
Yes. Our work covers the whole of Scotland, and Dalserf is part of that. Just email us at info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear quote.
I let a flat near Larkhall station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can go on one quote. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we’ll send you a clear quote.
Can you reseal over the builder’s sealant?
No. The old sealant is cut out fully, then clean and prime the joint, and a new bead applied.
Do I need to be at home?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Who should fix failed sealant in a new build?
Report it to the builder first while you are covered. If it isn’t resolved, we will cut it out and reseal it.
Should I wait before resealing?
Any seal that’s leaking should be redone straight away. Cosmetic gaps can wait until the first year or two of movement has passed.
Do you take on second-fix sealing for builders?
Yes. Plot mastic and second-fix sealing for developers is part of our work. Send us the plot schedule and we’ll quote.
Should I try DIY first?
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.

How we quote for new build mastic
We quote each job individually. These are the things that affect it:
- Whether there’s mould to deal with
- Whether the work is at height
- How much old sealant there is and how hard it is to remove
- The size of the job
Some things make a job bigger or smaller: 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 we need to know
When you call or email, these details help:
- What’s wrong with the joints now
- Any access issues, like height or stairs
- Roughly how big the job is
- Whether it’s a home or a business
We quote each job on its own, so the first step is telling us about yours. Simply send an email to info@mrmastic.co.uk and describe the job.
Honest limits
Sealant is not the answer to every problem, and we’d rather say so up front. It will not solve:
- Structural cracks in walls or ceilings
- Deciding who is responsible under a builder’s warranty
- Plumbing faults behind the sealant
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly before you book.
Surfaces we seal
- Show homes
- Windows & doors
- Bathrooms & en suites
- Plot handovers
- Kitchens
- Skirting & floors
Leave it or put it right?
If you’re still in the builder’s snagging or warranty period, ask them to put it right first. If it keeps failing or is not dealt with, we can reseal it properly. 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 each one gets its own quote. Size, access and the product the joint needs all make a difference.
