New homes and floors in Hairmyres
The west of Scotland 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, and as the frame dries and settles, skirting and sealant joints can open up.
Around Hairmyres, as everywhere, new build mastic is only as good as the preparation behind it.
Hairmyres is about 1 mile west of East Kilbride, in South Lanarkshire.

New build mastic for homes and businesses in Hairmyres
Some new-home owners let the house settle before resealing. That makes sense for small gaps that are just cosmetic, but a failed shower or bath seal shouldn’t wait. If you have new-build shower sealant that has already split and kitchen sealant that has pulled off the wall, we can put it right, on skirting & floors, bathrooms & en suites and kitchens alike.
Work in a place like Hairmyres is planned ahead, journey included. Outdoor plot mastic needs dry weather, but indoor floor and skirting joints can be sealed whatever the forecast.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

What sealant work can’t fix
Some problems need a builder, plumber or other trade rather than us:
- A tray or bath that isn’t properly supported, until it’s fixed
- Plumbing faults behind the sealant
- Deciding who is responsible under a builder’s warranty
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think before you book.
Joints and surfaces we work on
- Plot handovers
- Windows & doors
- Skirting & floors
- Show homes
- Bathrooms & en suites

Leave it or put it right?
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Resealing promptly protects the new finishes around it. In an older home around Hairmyres, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Doing several joints on one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will give you a clear price for the lot.
Why book with us
- More than 20 years in sealant work
- Neat joints and a tidy finish
- Arbo and Everbuild products
- Domestic, commercial and hotel work
When to call us in Hairmyres
On many sites, sealant goes on in the final rush before handover. Joints aren’t always cleaned of dust or primed, so the bead never bonds properly.
The problems people normally mention when they call are:
- Kitchen sealant that has pulled off the wall
- New-build shower sealant that has already split
- Sealant work across a run of new homes
- Gaps opening as the house dries out and settles
For new homes near Hairmyres station, it’s worth checking the sealant early, while snags are still fresh.
What your quote should include
- Who turns up on the day
- What the cure time is
- What product goes in the joint
- Which colour the sealant will be

What else we do in Hairmyres
How it works
When we get to you, 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. Somewhere like Hairmyres may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out down to clean surfaces.
- 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.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Clear items away from the joints we’re working on
- Tell us about any water getting in
Getting a quote
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. Whenever you’re ready, email us at info@mrmastic.co.uk.

Looking after it afterwards
So the new joints stay in good condition:
- Don’t seal over failed sealant yourself
- Photograph failed sealant before it’s redone
- Open a window or run the fan after bathing
- Report sealant problems to your builder during the snagging period
Watch the joints as the house settles. Hairline gaps can open as timber and plaster dry, and they’re simple to reseal once movement has slowed.
If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.
What affects the cost of new build mastic
Your quote is based on your job. We look at:
- Whether old sealant or filler has to be cut out
- Working hours on commercial sites
- The size of the job
- Which sealant suits the joint
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
Helping us quote
Photos help, but a description is a good start. Please mention:
- The problem you’ve noticed
- Pictures of the joints, sent by email
- The rough size of the job
- Whether it’s a home or a business
We quote each job on its own, so the first step is telling us about yours. Just email us at info@mrmastic.co.uk with the details and send photos if you have them.
Different surfaces, different methods
Skirting and floors
Gaps under skirting are one of the most common new-build snags. We seal it with a flexible sealant that copes with the movement.
Kitchens
New-kitchen sealant is often applied in a rush. We take it out and reseal neatly, colour-matched where it shows.
