About our new build mastic in Kilmahog
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. In both, preparation makes the difference. We work on skirting & floors, show homes and plot handovers, and people most often call us about new-build shower sealant that has already split and gaps behind new kitchen upstands.
For a place like Kilmahog, 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.
Every job comes with a 12-month guarantee, wherever you are in Stirling.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Clean sealant with mild detergent, not abrasives
- Put sealant faults on your snagging list early
- Get a leaking seal dealt with straight away
- Photograph failed sealant before it’s redone
Follow the cure time we give you before the area gets wet. Most silicones need around a day.
Lifting sealant traps moisture and mould behind it. Resealing before mould gets in saves a harder job later.

Surface by surface
Show homes
Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish to a tidy standard. Tell us when the home is open so we can plan around it.
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
When to call us in Kilmahog
A new house holds a lot of water from the build, and it dries out over the first couple of years. Drying timber shrinks and pulls joints apart and the sealant has to cope with the movement.
If you can see any of these, it’s time to have the joints looked at:
- Joints pulling apart as timber shrinks
- Beads laid onto grit and dust from the build
- Sealant work across a run of new homes
- Frame joints opening as the plaster dries
In and around Kilmahog, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

- Are they insured?
- Whether they seal over old material or remove it
- Who does the work, and how experienced they are
DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
How it works
On the day, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before we start. The work generally takes a few hours in a single home. In smaller Scottish places, parking is normally less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely down to clean surfaces.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
Before we arrive
- Keep children and pets away from the work area
- Try not to wet indoor joints just before the visit
- Tell us about any water getting in

What affects the cost of new build mastic
For a quick quote, just ask. What matters most is:
- Any mould that needs treating
- The amount of work
- How many areas need sealing
- Whether old sealant or filler has to be cut out
The cost reflects the work involved, not guesswork. That is why we ask a few questions first.
What to tell us for a quote
Photos by email are helpful but not essential. Please mention:
- How many joints, rooms or windows are involved
- What the problem is, such as mould, gaps, leaks or cracking
- A few pictures by email, if you can
- Whether it’s a home or a business
For a quick quote, get us on the phone, or email us if that is easier. Tell us about the joints that need doing and we’ll talk you through the work.
New homes and floors in Kilmahog
Kilmahog is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for plot mastic and the sealant in new homes to keep out. Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up.
Whether the job is in Kilmahog itself or nearby, the right material for each joint matters as much as a neat finish.
