New build mastic in Leverburgh, done properly
Some new-home owners let the house settle before resealing. That makes sense for small gaps that are just cosmetic, but a seal that’s letting water through needs doing now. We are often asked to deal with new-build shower sealant that has already split and frame joints opening as the plaster dries, on plot handovers, windows & doors and bathrooms & en suites.
Around smaller Scottish places like Leverburgh, new homes tend to be single plots or small developments. Each needs its sealant and floor joints finished as carefully as on a big site.
You get a one-year guarantee, the same in Leverburgh as everywhere else we work.

How the job changes by surface
Show homes
In a show home, the sealant is on display. We lay neat, even beads in colours to suit the finishes.
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We cut out the cracked bead and reseal with a flexible sealant that suits the frame.
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Watch for new gaps as the house dries out
- Don’t wait for the house to settle if water is getting through
- Ventilate bathrooms well, especially in the first year
- Put sealant faults on your snagging list early
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Small faults turn into leaks if left over time.
How we quote for new build mastic

- When we can work, for business premises

What happens on the day
You don’t need to clear the whole room or building, only the area right around the joints. We protect the rest, and the job takes anything from a few hours to several days, depending on the number of plots in most cases. In smaller Scottish places, parking is normally less of an issue than access and distance. Let us know how to find you and how to reach the joints.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
Before we arrive
- Let us know about earlier repairs to the joints
- Let us know about parking restrictions
- Clear the area around the work
Getting a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that is easy.
Related advice
Should I try it myself first?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Joints and finishes in Leverburgh homes
Leverburgh is within about 1 mile of the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. The west of Scotland is wetter than the east, which means plot mastic and the sealant in new homes has to cope with a lot of rain.
Whether the job is in Leverburgh itself or nearby, the right material for each joint matters as much as a neat finish. In and around Leverburgh, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

What sealant work can’t fix
New sealant can’t fix everything, and we’d rather say so up front. Sealant won’t put right:
- Leaking fittings rather than failed sealant
- Broken tiles or a split tray
- Your warranty claim itself, which is between you and the builder
If you’re not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer before booking.

Your questions about new build mastic in Leverburgh
Is Leverburgh within the area you cover?
Yes, we do. We work across all of Scotland, islands included, and smaller places are part of that. Longer journeys are simply planned in advance.
Is there a guarantee on new build mastic in Leverburgh?
Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Will you leave a mess?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Why has my new-build shower seal failed already?
It’s common, and there are normally two reasons: movement as the house dries and settles, and sealant laid onto dust without primer. A proper reseal deals with both.
Can landlords and businesses book you?
Yes, regularly. We can quote for several properties at once, and between tenancies is a good time for the work.
What colour sealant will you use?
Most bathroom joints are white or clear, but other colours are available. We match the colour to the finish before we begin.
Does someone need to be in?
It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
