Landlords, agents and businesses in Heriot
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can be quoted together.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
About our new build mastic in Heriot
Some owners wait for the first year’s movement before having joints redone. That makes sense for small gaps that are just cosmetic, but a failed shower or bath seal shouldn’t wait. We work on skirting & floors, bathrooms & en suites and windows & doors, and the jobs we see most are messy sealant that spoils new finishes and second-fix sealing on new plots.
Many newer homes in Scotland are timber-framed and settle as they dry out, so skirting and floor joints can open up. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.
You’re covered for a year from the day we finish. If there’s a problem with it, please email us at info@mrmastic.co.uk.

What happens if it’s left?
Resealing everything on a snagging list in one visit is normally simpler than chasing joints one at a time. You get one visit and one clear quote. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Wait for the cure time before using a resealed shower
- Keep photos and emails about snagging items
- Get a leaking seal dealt with right away
- Use the extractor fan every time you shower
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
Signs you need new build mastic in Heriot
A new house holds a lot of water from the build, which takes a year or two to dry out. Drying timber shrinks and pulls joints apart and the sealant has to cope with the movement.
It’s worth asking for a quote if you see:
- Sealant that never bonded to the surface
- Messy sealant that spoils new finishes
- Gaps between new skirting and floors
- New-build shower sealant that has already split
Whether the job is in Heriot itself or nearby, the right material for each joint matters as much as a neat finish.

FAQs for Heriot
Is there a guarantee on new build mastic in Heriot?
Every job comes with our one-year guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Do you cover Heriot for new build mastic?
Yes, Heriot is within the area we cover. Our work covers the whole of Scotland. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing.
Can I add another job to the visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Can you work from my snagging list?
Yes. Snagging lists are a common starting point for us. We will go through the sealant items and agree what we will do.

How long should I leave it?
Cure times vary by product. Before we leave, we’ll tell you the cure time.
