How we handle new build mastic in Blackness
We never seal over a failed new-build bead. Fresh silicone can’t bond to the old layer, so it all comes out before we clean, dry and reseal. We work on windows & doors, plot handovers and skirting & floors, and the jobs we see most are cracked sealant around new window and door frames and new-build shower sealant that has already split.
Scotland’s cities are still adding new flats and houses, and in new homes, sealant and floor joints are often among the first snags, in Blackness as anywhere.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

What the job involves on each surface
Show homes
We seal show-home bathrooms, kitchens and frames. Tell us when the home is open so we can plan around it.
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
Landlord and commercial work in Blackness
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.

What affects the quote in Blackness
The price is agreed before any work begins. It’s based on:
- Working hours on commercial sites
- Mould in or behind the old joints
- The product the joint needs
- Whether old sealant or filler has to be cut out
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.
Helping us quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- The rough size of the job
- The problem you’ve noticed
- Whether it has been sealed before
- Access, such as stairs, a lift or height
Asking for a quote is easy: let us know the job and the location and its rough size. A few photos by email make the job easier to understand.
What sealant work can’t fix
In fairness, there are a few things sealant will not fix:
- Structural cracks in walls or ceilings
- Cracked trays, tiles or worktops
- Leaking fittings rather than failed sealant

Blackness: your questions answered
Can you help a landlord with a rental near Dundee station?
Yes, rental work is part of what we do. You can email us at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before we start.
Is there a guarantee on new build mastic in Blackness?
Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
My new home is still under warranty. Should I contact you?
Your builder, if you’re still in their snagging or warranty period. After that, or if their repair keeps failing, we can do it and our work is guaranteed for a year.
Do you hold any approvals?
Yes. We’re approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
When is the sealant fully cured?
That depends on the sealant used, so follow the cure time we give you when we finish.
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.
Should I wait before resealing?
If the seal has failed and water is getting in, do it now. Small gaps that are just cosmetic can be resealed once movement has slowed.
Why it’s worth doing now in Blackness
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it can’t bond to what’s underneath. A lasting seal starts with removing the old one completely. Scottish rain finds any gap around a frame or wall joint, and in a tall building in Blackness, damp can travel a long way before it shows.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please email us at info@mrmastic.co.uk.

New build mastic around Blackness
Blackness is close to the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. Timber frame is common in newer Scottish homes, so skirting and sealant joints can open up as the building settles.
Around Blackness, as everywhere, new build mastic is only as good as the preparation behind it.
