About our new build mastic in Portskerra
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first. We work on kitchens, plot handovers and bathrooms & en suites, and the jobs we see most are joints pulling apart as timber shrinks and internal frame sealant that has split.
Many newer homes in Scotland are timber-framed and settle as they dry out, which shows as gaps at skirtings and floor joints. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.
Every job is covered by our one-year guarantee, wherever you are in Highland.

How it works
A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and tidy away. Most jobs take a few hours in a single home. In smaller Scottish places, parking is generally less of an issue than access and distance. Let us know how to find you and how to reach the joints.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- 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.
Getting ready for the visit
- Tell us about any water getting in
- Let us know about earlier repairs to the joints
- Try not to wet indoor joints just before the visit

Advice
Landlord and commercial work in Portskerra
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.
We also work for property managers and facilities teams. Several sites can be quoted together.
How to look after the new joints
To keep the joints looking good and working properly:
- Wait for the cure time before using a resealed shower
- Photograph failed sealant before it’s redone
- Look at the sealant regularly in the first couple of years
- Don’t seal over failed sealant yourself
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
DIY versus a professional finish
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
When it isn’t the sealant
Before you book, it’s worth knowing the limits too:
- Leaks from pipes, valves or wastes, which need a plumber
- Baths and trays that move too much for sealant to cope with
- Cracking that points to a structural problem
If you’re not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer before booking.
