What new build mastic looks like in St Katherines
Timber frame is common in newer Scottish homes, so skirting and sealant joints can open up as the building settles.
For jobs in and around St Katherines, choosing the right material for each joint is as important as a tidy finish.

New build mastic for homes and businesses in St Katherines
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. In both, preparation makes the difference since hurried prep is behind a lot of new-build failures. We’re often asked to deal with sealant that never bonded to the surface and cracked sealant around new window and door frames, across bathrooms & en suites, skirting & floors and windows & doors.
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.
Whatever the size of the job, it’s backed by our one-year guarantee in St Katherines and across Aberdeenshire.

How it works
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take anything from a few hours to several days, depending on the number of plots. 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.
- We go through the snagging list or plot schedule and agree the joints to do.
- The old bead comes out in full, with no layer left behind.
- We clean off dust from the build and prime the surfaces where the product needs it.
- 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.
Getting ready for the visit
- Clear the area around the work
- Tell us about any previous sealing or DIY attempts
- Tell us if parking is tricky

Advice
Different surfaces, different methods
Plot handovers
Developers can send the plot schedule and specification and we will quote. We seal bathrooms, kitchens, frames and floors as agreed.
Windows and doors
A draught at a new window can be a missed or failed joint. We look at the joints and reseal where needed.
What happens if it’s left?
For developers, getting the sealant right first time saves return visits. Snagging visits for failed sealant cost time on every plot and most come down to preparation. Around St Katherines, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
Combining jobs into one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.
Why us?
- One-year guarantee on every job
- Full insurance on every job
- Sanitary silicone with an anti-fungal additive in wet areas
- White, clear, grey or another colour, product permitting

Common questions in St Katherines
What guarantee comes with new build mastic in St Katherines?
All our work, in St Katherines and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Is St Katherines within the area you cover?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll tell you what we are using.
Is it worth trying it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Do you use white or clear sealant?
Most bathroom joints are white or clear, but other colours are available. We match the colour to the finish and agree it with you.
Do you work for developers?
Yes. Second-fix sealing in bathrooms, kitchens, frames and floors is part of what we do. We clean and prime joints properly to keep callbacks down.
Can you quote for more than one area?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Do you take out the old sealant first?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Looking after it afterwards
Aftercare is simple:
- Don’t wait for the house to settle if water is getting through
- Wipe joints with warm soapy water
- Record problems with dated photos
- Don’t seal over failed sealant yourself
Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry, and they’re simple to reseal once movement has slowed.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
What we are called out for in St Katherines
The first winter with the heating on dries a new home quickly. Gaps open along skirting, frames and worktops and cracks appear in the sealant.
Most people get in touch after spotting something like this:
- Smeared, uneven beads picked up at snagging
- Skirting joints opening in the first winter
- Joints pulling apart as timber shrinks
- Cracked sealant around new window and door frames
Around St Katherines, as everywhere, new build mastic is only as good as the preparation behind it.
