How we handle new build mastic in Dunbeath
Some new-home owners let the house settle before resealing. That makes sense for small gaps that are just cosmetic, but a failed shower or bath seal shouldn’t wait. Common call-outs are for new-build shower sealant that has already split and cracks appearing as a new home settles, on skirting & floors, windows & doors and kitchens.
New homes in smaller Scottish places are often single plots, self-builds or small developments. Each needs its sealant and floor joints finished as carefully as on a big site.
There’s a 12-month guarantee on every job, large or small.

What else we do in Dunbeath
Why act early in Dunbeath
A quick bead over the top of the old sealant can look fine at first, but it won’t 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.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and send you a clear quote before we start.
What you get with us
- A sealant colour to suit the surroundings
- You choose the colour before work begins
- Any old sealant cut out fully, not covered over
- A 12-month guarantee on all work
New build mastic around Dunbeath
Dunbeath is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up.
Around Dunbeath, as everywhere, new build mastic is only as good as the preparation behind it.

A new house holds a lot of water from the build, and it dries out over the first couple of years. Drying timber shrinks and pulls joints apart.
Most people get in touch after spotting something like this:
- Sealant that never bonded to the surface
- Leaking shower tray seals in a new home
- Messy sealant that spoils new finishes
- Plot mastic for developers ahead of handover
For jobs in and around Dunbeath, choosing the right material for each joint is as important as a tidy finish.

Your questions about new build mastic in Dunbeath
Is new build mastic in Dunbeath guaranteed?
Every job comes with our 12-month guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Can you do new build mastic in Dunbeath?
Yes, Dunbeath is within the area we cover. We work across all of Scotland. You can send an email to info@mrmastic.co.uk and tell us what needs doing.
Which products do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Do you work for landlords and businesses?
Yes, often. We can quote for several properties at once.
Why has my new-build shower seal failed already?
A new house dries and settles for a year or two, and sealant is often rushed onto dusty, unprimed surfaces. Both lead to early failure.
I rent my home. Can I book you?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Can you quote for more than one area?
Yes, and it often makes sense. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Surface by surface
Plot handovers
Taking time over preparation reduces return visits. We clean out building dust before sealing and prime where the product needs it.
Windows and doors
On new builds, external frame sealant can be patchy. We reseal it with a weatherproof, flexible sealant.

What affects the cost of new build mastic
Call for a quick quote. The main things that affect it are:
- How many rooms, windows or areas are involved
- How easy the joints are to reach
- Any mould that needs treating
- Whether old sealant or filler has to be cut out
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.
What to tell us for a quote
When you call or email, it’s useful to know:
- How many joints, rooms or windows are involved
- Whether it’s a home or a business
- Where the job is, and your postcode
- What the problem is, such as mould, gaps, leaks or cracking
Asking for a quote is easy: let us know the job and the location. Photos by email help us understand the job.
Looking after it afterwards
So the new joints stay in good condition:
- Open a window or run the fan after bathing
- Report sealant problems to your builder during the snagging period
- Look at the sealant regularly in the first couple of years
- Wait for the cure time before using a resealed shower
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black saves a harder job later.
