Netherburn questions
Is Netherburn in your area for new build mastic?
Yes. We work across all of Scotland, and Netherburn is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job.
Is Netherburn within the area you cover?
Yes, Netherburn is covered. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
Do I have to be there?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Should I go to my builder first?
If you are still within the builder’s snagging or warranty period, report it to them first. If it isn’t sorted, or keeps failing, get in touch with us.
Do you hold any approvals?
Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
I’m a tenant. Can you help?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
Do you work for developers?
Yes. We carry out plot mastic and second-fix sealing for builders and developers. Send us the plot schedule and we’ll quote.
New build mastic in Netherburn, 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 work on plot handovers, bathrooms & en suites and skirting & floors, and the jobs we see most are gaps between new skirting and floors and internal frame sealant that has split.
For a place like Netherburn, the journey and access are planned in advance. Outdoor plot mastic needs dry weather, but indoor floor and skirting joints can be sealed whatever the forecast.
Big or small, you get the same one-year guarantee.

Different surfaces, different methods
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
Show homes
We seal show-home bathrooms, kitchens and frames ready for viewings. We will plan around viewing times.
When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Leaks from pipes, valves or wastes, which need a plumber
- A tray or bath that is not properly supported, until it’s fixed
- Damaged fittings that need replacing
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly before you book.
What we seal
- Show homes
- Skirting & floors
- Kitchens
- Plot handovers
- Windows & doors
- Bathrooms & en suites
What we are called out for in Netherburn
Once people move in, baths and trays take weight and bed down. A bath sealed empty drops slightly when filled, straining the joint and the sealant may split.
Signs it’s time to call us include:
- Untidy sealant flagged on a snagging list
- Cracked sealant around new window and door frames
- Shower seals failing in the first year or two
- Plot mastic for developers ahead of handover
If you’ve bought a new home near Carluke station, the sealant around baths, showers and frames is worth checking in the first year or two.

- The failed sealant is removed completely.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
Preparing for the visit
- Mention if the joints have been sealed before
- Move anything stored near the joints
- Plan for the work area to be out of bounds to pets and children

Related advice
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
