New build mastic in Dunkeld, done properly
We work in new homes and on new-build sites across Dunkeld. One shower or a whole phase of plots, the method does not change: cut out, clean, prime where needed and reseal neatly. We work on plot handovers, bathrooms & en suites and skirting & floors, and people most often call us about second-fix sealing on new plots and skirting joints opening in the first winter.
Timber frame is common in newer Scottish homes, and it settles over the first years, so skirting and floor joints can open up. In older homes, timber floors move through the year too.
There’s a 12-month guarantee on every job, large or small.

For a place like Dunkeld, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- Each joint is checked for movement before we start.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
Before we arrive
- Let us know about stairs, lifts or work at height
- On commercial sites, let us know about site rules

Advice
How to look after the new joints
After the cure time, these simple habits help:
- Wipe joints with warm soapy water
- Report sealant problems to your builder during the snagging period
- Watch for new gaps as the house dries out
- Avoid running a DIY bead over the old one
Wipe the sealant with warm soapy water. Avoid abrasive pads and strong solvents, which can damage the surface.
Do not let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you so report it promptly.

Is Dunkeld within the area you cover?

There can be a smell while the sealant cures. Ventilation helps.

How the job changes by surface
Skirting and floors
New homes often develop a gap between skirting and floor. We seal it with a flexible sealant that copes with the movement.
Plot handovers
We work through plots to your schedule, sealing each room ready for handover. Joints are prepared properly before sealing.
DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Do you need new build mastic in Dunkeld?
New homes are full of moisture from plaster, screed and concrete, which takes a year or two to dry out. Drying timber shrinks and pulls joints apart, and sealant that can’t keep up splits.
Look out for these signs:
- Gaps opening as the house dries out and settles
- Smeared, uneven beads picked up at snagging
- Worktop and upstand sealant coming away
- Cracked sealant around new window and door frames
For new homes near Dunkeld & Birnam station, it’s worth checking the sealant early, while snags are still fresh.
Questions to ask before you book
- How the surfaces are prepared before sealing
- Who does the work, and how experienced they are

- What insurance they hold
