New build mastic in California
For builders and developers, we work through plots to the schedule you give us. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over with a sealant suited to each area. We work on show homes, bathrooms & en suites and skirting & floors, and people most often call us about kitchen sealant that has pulled off the wall and gaps opening as the house dries out and settles.
Many newer homes in Scotland are timber-framed and settle as they dry out, so skirting and floor joints can open up. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.
Each job carries a 12-month guarantee, whatever its size.

Your questions about new build mastic in California
Do you cover smaller places like California?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you cover California for new build mastic?
Yes, California is within the area we cover. We work across all of Scotland. Just send an email to info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear price.
Do the sealants smell?
There can be a smell while the sealant cures. Ventilation helps.
Is it worth trying it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Can you quote for more than one area?
Yes, and it often makes sense. Doing several areas at once is usually more efficient.
What does new build mastic cost?
Size, access and the old material all affect the cost. Call for a quick quote.
Do you work through snagging lists?
Yes. Photos of each sealant item help us quote. Items that need a plumber, tiler or the builder are flagged.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We’ll tell you what we are using and why.
Do you need new build mastic in California?
The first winter with the heating on dries a new home quickly. Skirting, frames and worktops pull away slightly.
The problems people generally mention when they call include:
- Frame joints opening as the plaster dries
- Sealant that never bonded to the surface
- Worktop and upstand sealant coming away
- New-build shower sealant that has already split
For new homes near Polmont station, it’s worth checking the sealant early, while snags are still fresh.

DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Why it’s worth doing now in California
Resealing everything on a snagging list in one visit is generally simpler than chasing joints one at a time. You get one visit and one clear quote. Around California, 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.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs. Ask us for a quote and we’ll go through it with you.

Different surfaces, different methods
Plot handovers
Send us the schedule and any sealant specification. Sealant work across the plot is covered as agreed.
Kitchens
New-kitchen sealant is often applied in a rush. We take it out and reseal neatly, colour-matched where it shows.
How it works
The work is kept neat and contained to the joints we’re treating, so you can carry on as normal. The job usually takes a few hours in a single home, and we tell you how long to leave it before we go. Around California, distance and access matter more than parking. Tell us how to find the property and how to reach the work.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely, with no layer left behind.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Before we arrive
- Keep pets and children clear of the area while we work
- On commercial sites, let us know about site rules
- Move anything stored near the joints
