New build mastic for homes and businesses in Lonemore
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. If you’re still within the builder’s snagging or warranty period, tell them first and if that stalls, we can do it. Typical jobs include messy sealant that spoils new finishes and gaps between new skirting and floors, on windows & doors, plot handovers and show homes.
Work in a place like Lonemore is planned ahead, journey included. Inside work goes ahead in any weather; outside mastic needs a dry day.
There’s a 12-month guarantee on every job, whatever its size.

Aftercare tips
After the cure time, these simple habits help:
- Record problems with dated photos
- Follow the cure time we give you
- Use the extractor fan every time you shower
- Check bath and shower seals every few months as the house settles
Do not stand on the bath edge or the lip of the tray in the first few weeks. If a bath or tray moves when you stand in it, get it looked at.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in saves a harder job later.
When something else is needed
To be straight with you, some problems need a different trade:
- Settlement cracks that need a surveyor
- Baths and trays that move too much for sealant to cope with
- Your warranty claim itself, which is between you and the builder
If in doubt, email us at info@mrmastic.co.uk and we will say what we think before booking.

New build mastic in Lonemore: local notes
Lonemore 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. Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles.
For jobs in and around Lonemore, choosing the right material for each joint is as important as a tidy finish. In and around Lonemore, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Lonemore is in Highland. Homes, rented property, offices and hotels in Lonemore can book us for new build mastic. Every job comes with our 12-month guarantee. We cover 253 towns and villages across Highland, from the larger towns to small villages.

What affects the cost of new build mastic
Every job gets its own quote. These are the things that affect it:
- Any mould that needs treating
- Whether old sealant or filler has to be cut out
- The number and length of the joints
- The type of sealant required
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.
Asking for a quote
There’s no need for technical detail. It helps if you can tell us:
- Roughly how big the job is
- Any previous sealing or DIY work
- The address or postcode of the job
- Pictures of the joints, sent by email
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we will talk you through what we’d do. When it suits you, send an email to info@mrmastic.co.uk.
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
What happens on the day
At the end, we look at the finished work together. The work normally takes a few hours in a single home, depending on the size of the job. Somewhere like Lonemore may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- The old bead comes out in full, with no layer left behind.
- Each joint is cleaned of dust and grit, then primed if required.
- We apply a sealant that suits each joint and tool it to a neat finish.
- We check every joint and tell you how long each needs to cure.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Mention any leaks or damp you’ve noticed
- Tell us about any previous sealing or DIY attempts

Surface by surface
Bathrooms and en suites
En suite showers are a common source of leaks into the room below. Resealing properly keeps water where it belongs.
Kitchens
As a new house dries, worktops and walls shift a little, opening gaps behind the upstand. A fresh flexible bead closes them.
Common questions in Lonemore
Is new build mastic in Lonemore guaranteed?
All our work, in Lonemore and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Do you cover smaller places like Lonemore?
Yes. Lonemore is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Should I wait before resealing?
It depends on whether water is getting through. Failed seals in wet areas need doing now, while small cosmetic gaps can wait a while.
Why has my new-build shower seal failed already?
Lots of new homes see sealant crack early. Rushed application on dusty surfaces makes it worse.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Do you work for letting agents?
Yes, often. Several properties can go on one quote, and between tenancies is a good time for the work.
Do you use white or clear sealant?
We use white, clear or a colour to suit the finishes. Tell us what you’d like when you get a quote.
Is it messy?
No. We work neatly, protect the area around the joints and tidy up afterwards.
