- Plot mastic for developers ahead of handover
How we handle new build mastic in Libberton
Developers send us the plot schedule and we work through it. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over using the right product for each joint. We work on skirting & floors, bathrooms & en suites and windows & doors, and common reasons people get in touch are gaps opening as the house dries out and settles and second-fix sealing on new plots.
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.
Our work is backed for twelve months.

Questions from Libberton
Do you work for landlords with property near Carstairs station?
Yes, landlords and agents are among the people we work for. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear price.
Do you cover smaller places like Libberton?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for hotels and businesses?
Yes. We have worked for hotels, offices and other businesses, and we are fully insured.
What colour sealant will you use?
Most bathroom joints are white or clear, but other colours are available. We choose one to suit the room and agree it with you.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status and we’re fully insured too.
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.
How long will you be here?
It depends on the size of the job, but as a guide it takes a few hours for most snagging lists, longer for a run of plots. We’ll give you a better idea when we quote.
When is the best time to reseal in a new build?
That depends on the joint. Failed seals in wet areas need doing now, while small cosmetic gaps can wait a while.
DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Places near Libberton
What else we do in Libberton
Do you need new build mastic in Libberton?
On many sites, sealant goes on in the final rush before handover. Dusty, unprimed joints are common, and the sealant sits on grit instead of the surface.
The most common problems we see are:
- Sealant that never bonded to the surface
- Messy sealant that spoils new finishes
- Gaps behind new kitchen upstands
- Joints pulling apart as timber shrinks
If you’ve bought a new home near Carstairs station, the sealant around baths, showers and frames is worth checking in the first year or two.
Questions to ask before you book
- Which sealant they’ll use, and why
- Is VAT in the price?
- Which colour the sealant will be
- What guarantee comes with the work
How to look after the new joints
Good habits help new joints last longer. A few tips:
- Report sealant problems to your builder during the snagging period
- Keep water off fresh sealant until it has cured
- Look at the sealant regularly in the first couple of years
- Clean sealant with mild detergent, not abrasives
Watch the joints as the house settles. Small gaps can appear as the house dries and can be resealed later.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Small faults turn into leaks if left.
What happens on the day
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for most snagging lists, longer for a run of plots and we leave things clean and tidy. Around Libberton, distance and access matter more than parking. Tell us how to find the property and how to reach the work.
- 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.
Before we arrive
- Move anything stored near the joints
- Tell us about any water getting in
- Let us know about parking restrictions

For landlords and businesses
We also work for property managers and facilities teams. Several sites can be quoted together, and we’re fully insured for the work.
In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
What the job involves on each surface
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. The joint is stripped back before the new bead goes in with baths filled first.
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We remove cracked sealant and apply a flexible one that suits the frame.
Honest limits
Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Settlement cracks that need a surveyor
- Disputes or warranty claims with your builder
- Baths and trays that move too much for sealant to cope with
If in doubt, drop us a line at info@mrmastic.co.uk and we will say what we think before booking.
Surfaces we seal
