What happens if it’s left?
The builder is usually the first port of call while the snagging or warranty period runs. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please email us at info@mrmastic.co.uk and we’ll talk you through it.

New build mastic for homes and businesses in North Dell
Building dust is behind a lot of failed new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the new bead bonds properly. We work on show homes, bathrooms & en suites and skirting & floors, and people most often call us about gaps between new skirting and floors and worktop and upstand sealant coming away.
Timber frame is common in newer Scottish homes, and it settles over the first years, which shows as gaps at skirtings and floor joints. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.
Your job is guaranteed for a year, as with all our work.

How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from a few hours to several days, depending on the number of plots, and the area is left clean. Somewhere like North Dell 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.
- Surfaces are cleaned of building dust and primed where needed.
- 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
- Mention if the joints have been sealed before
- On commercial sites, let us know about site rules
- Move anything stored near the joints

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

Aftercare tips
Aftercare is simple:
- Photograph failed sealant before it’s redone
- Report sealant problems to your builder during the snagging period
- Get a leaking seal dealt with right away
- Avoid running a DIY bead over the old one
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak over time.
New build mastic in North Dell: local notes
North Dell 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. 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 North Dell itself or nearby, the right material for each joint matters as much as a neat finish. Around North Dell, as everywhere, new build mastic is only as good as the preparation behind it.

Different surfaces, different methods
Skirting and floors
Floors and skirting move as the house dries and the heating runs. We use a flexible product rather than caulk painted or coloured to suit.
Show homes
Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish ready for viewings. Tell us when the home is open so we can plan around it.
