What affects the cost of new build mastic
The price is agreed before any work begins. It’s based on:
- Which sealant suits the joint
- Any mould that needs treating
- When we can work, for business premises
- How many areas need sealing
Doing several joints on one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.
What we need to know
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- The address or postcode of the job
- How we’d reach the joints
- Photos by email, if that’s easy
- How many joints, rooms or windows are involved
There’s no standard price list, because every job is different. Instead, your job gets its own clear quote. To arrange one, send an email to info@mrmastic.co.uk.
About our new build mastic in Low Valleyfield
A new build should have a neat, sound bead at every joint. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. We’re often asked to deal with skirting joints opening in the first winter and leaking shower tray seals in a new home, on kitchens, skirting & floors and windows & doors.
Many newer homes in Scotland are timber-framed and settle as they dry out, so skirting and floor joints can open up. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Common problems we fix in Low Valleyfield
Not every new-build joint gets the right sealant: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Neither lasts long.
People usually contact us after spotting one of these:
- Gaps behind new kitchen upstands
- Cracked caulk along new skirting
- Sealant work across a run of new homes
- Untidy sealant flagged on a snagging list
For jobs in and around Low Valleyfield, choosing the right material for each joint is as important as a tidy finish.
What your quote should include
- Whether VAT is included
- When the joint can take water or movement
- Whether the sealant suits the joint
- How the colour is chosen
Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Watch for new gaps as the house dries out
- Act quickly if a seal starts to leak
- Raise failed sealant with the developer while you are covered
- Record problems with dated pictures
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it as they wear the bead.
If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.
What happens if it’s left?
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it will not bond to the old layer. A lasting seal starts with removing the old one completely. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

In and around Low Valleyfield, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

What happens on the day
At the end, we look at the finished work together. The visit itself usually takes a few hours for most snagging lists, longer for a run of plots, depending on the amount of work.

- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
How to prepare
- For business premises, tell us about site rules or sign-in
- Try not to wet indoor joints just before the visit
- Let us know if you’ve seen damp or leaks
