What new build mastic looks like in Perth
Timber frame is common in newer Scottish homes, so skirting and sealant joints can open up as the building settles.
For new homes near Perth station, it’s worth checking the sealant early, while snags are still fresh.

New build mastic in Perth
Building dust is behind a lot of failed new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the new bead bonds properly instead of bonding to the dust. We are often asked to deal with gaps behind new kitchen upstands and shower seals failing in the first year or two, across kitchens, show homes and windows & doors.
Commercial units and shops in a town like Perth have floors with joints that need resealing as they wear. Sealing them before the edges break up saves a bigger repair.
Our work is backed for twelve months.

Do you need new build mastic in Perth?
The wrong product is sometimes used in the wrong place: caulk where water collects, or a rigid product on a moving joint. Both fail early.
Keep an eye out for any of the following:
- Plot mastic for developers ahead of handover
- Messy sealant that spoils new finishes
- Cracks appearing as a new home settles
- Gaps behind new kitchen upstands
Around Perth, as everywhere, new build mastic is only as good as the preparation behind it.
Questions to ask before you book
- How the joint is cleaned and prepared
- What happens if they find a problem under the old sealant
- Whether they’re fully insured
- Whether VAT is included

Keeping the joints in good condition
Aftercare is simple:
- Avoid running a DIY bead over the old one
- Ventilate bathrooms well, especially in the first year
- Follow the cure time we give you
- Record problems with dated photos
Keep pictures of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black saves a harder job later.
FAQs for Perth
What guarantee comes with new build mastic in Perth?
All our work, in Perth and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Do you work for landlords with property near Perth station?
Yes, we work for landlords and letting agents. You can send an email to info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before any work starts.
When is the sealant fully cured?
It depends on the product. We tell you how long to leave it before we go.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.
Is there any odour?
It depends on the product. Some products have a noticeable smell, others very little.
What sealant do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
How long will you be here?
It depends on the size of the job, but most jobs take a few hours for most snagging lists, longer for a run of plots. We will tell you when we quote.
Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

What affects the cost of new build mastic
We quote each job individually. This is what makes a difference:
- How many areas need sealing
- Access and height
- The size of the job
- The type of sealant required
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
What we need to know
You don’t need to know the technical terms. Just tell us:
- Photos by email, if that is easy
- Where the job is, and your postcode
- Whether it has been sealed before
- Roughly how big the job is
If you’re in Perth and need new build mastic, email us at info@mrmastic.co.uk. Tell us what the problem is and where, and we will agree the price before any work begins.
Honest limits
To be straight with you, some problems need a different trade:
- A tray or bath that is not properly supported, until it’s fixed
- Structural cracks in walls or ceilings
- Plumbing faults behind the sealant
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly.
