New build mastic in Stepps, done properly
For builders and developers, we work through plots to the schedule you give us. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover with a sealant suited to each area. Common call-outs are for shower seals failing in the first year or two and cracks appearing as a new home settles, on kitchens, bathrooms & en suites and plot handovers.
For a place like Stepps, 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.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Can I do it myself?
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 does not work out, we can still put it right.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

What new build mastic looks like in Stepps
Stepps is in the west of Scotland, which is wetter than the east, which means plot mastic and the sealant in new homes has to cope with a lot of rain. Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles.
Around Stepps, as everywhere, new build mastic is only as good as the preparation behind it.

Looking after it afterwards
A little care helps the new joints last. Our advice:
- Clean sealant with mild detergent, not abrasives
- Get a leaking seal dealt with straight away
- Use the extractor fan every time you shower
- Put sealant faults on your snagging list early
Watch the joints as the house settles. Small gaps can appear as the house dries and can be resealed later.
Early snagging is easier snagging. Small faults turn into leaks if left in a busy bathroom.
Do you need new build mastic in Stepps?
Once people move in, baths and trays take weight and bed down. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used and can tear.
It’s worth asking for a quote if you see:
- Shower seals failing in the first year or two
- Cracks appearing as a new home settles
- Gaps behind new kitchen upstands
- Second-fix sealing on new plots
For new homes near Stepps station, it’s worth checking the sealant early, while snags are still fresh.

How the job changes by surface
Skirting and floors
As timber and screed dry, skirting and floors shift. We use a flexible product rather than caulk.
Show homes
Show homes need sealant that looks right from day one. We lay neat, even beads in colours to suit the finishes.
Why act early in Stepps
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 Stepps, water from a failed joint in an older stone home can soak into timber and plaster.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.
Why book with us
- Approved under the ARBOMaster scheme
- We never seal over old sealant
- You choose the colour before work begins
- Every job guaranteed for a year

What we do, step by step
Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for most snagging lists, longer for a run of plots. Outdoor work around Stepps depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- We go through the snagging list or plot schedule and agree the joints to do.
- We cut out every bit of the failed or messy sealant.
- Surfaces are cleaned of building dust and primed where needed.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Each area is checked and left with its cure time.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- For indoor joints, keep the area dry beforehand if you can
- Mention any sign-in or site rules at work premises

Stepps questions
Do you cover smaller places like Stepps?
Yes, Stepps is covered. We work across all of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
I let a flat near Stepps station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear quote.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Does someone need to be in?
Access is agreed with you when the job is booked. Indoors, that normally means someone at home.
Do you use white or clear sealant?
We use white, clear or a colour to suit the finishes. Tell us what you’d like when you get a quote.
Are you fully insured?
Yes. We’re fully insured.
My new home is still under warranty. Should I contact you?
Your builder, if you’re still in their snagging or warranty period. After that, or if their repair keeps failing, we can do it with our one-year guarantee.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
