Problem with your new-build sealant joints in Stonehouse? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.
- Untidy sealant flagged on a snagging list

How it works
We keep the work tidy and contained to the area we are working on, so you can carry on as normal. The job usually takes anything from a few hours to several days, depending on the number of plots, and we explain the cure time before we leave. In smaller Scottish places, parking is normally less of an issue than access and distance. Let us know how to find you and how to reach the joints.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely 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.
Getting ready for the visit
- Let us know about parking restrictions
- Keep pets and children clear of the area while we work
- Try not to wet indoor joints just before the visit

Advice
New build mastic in Stonehouse, done properly
We work in new homes and on new-build sites across Stonehouse. One shower or a whole phase of plots, the method does not change: remove, clean, prime where needed, then a neat new bead. We work on plot handovers, windows & doors and show homes, and the jobs we see most are beads laid onto grit and dust from the build and cracks appearing as a new home settles.
Work in a place like Stonehouse is planned ahead, journey included. Inside work goes ahead in any weather; outside mastic needs a dry day.
We stand behind the work with a 12-month guarantee, so you’re not left on your own once the job is done.

Common problems we fix in Stonehouse
Later trades and the final clean can damage fresh sealant. A bead disturbed before it has cured may never seal properly and it shows once the home is in use.
Most people get in touch when they notice one of these:
- Shower seals failing in the first year or two
- Second-fix sealing on new plots
- Internal frame sealant that has split
- Joints pulling apart as timber shrinks
If you’ve bought a new home near Larkhall station, the sealant around baths, showers and frames is worth checking in the first year or two.

Joints and finishes in Stonehouse homes
Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles.

Keeping the joints in good condition
After the cure time, these simple habits help:
- Open a window or run the fan after bathing
- Record problems with dated photos
- Do not seal over failed sealant yourself
- Clean sealant with mild detergent, not abrasives
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant and protects the rest of the house.
Honest limits
It helps to know what we cannot do:
- Movement caused by a poorly fitted tray or bath
- Damaged fittings that need replacing
- Leaks from pipes, valves or wastes, which need a plumber

Different surfaces, different methods
Plot handovers
Taking time over preparation reduces return visits. Dust from the build is removed first and prime where the product needs it.
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
Stonehouse: your questions answered
Can you do new build mastic in Stonehouse?
Yes, Stonehouse is within the area we cover. We work across all of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Do you work for landlords with property near Larkhall station?
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 price.
When is the best time to reseal in a new build?
Any seal that is leaking should be redone right away. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
Will you just run a new bead over the existing one?
No. Sealing over old sealant looks fine for a few weeks, then lifts. We remove every bit of the old bead before resealing.
Will the old sealant be removed?
Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Stonehouse, along with the rest of our area.
Can I do it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Do you work through snagging lists?
Yes. Send it with photos and we will quote for the sealant items. Items that need a plumber, tiler or the builder are flagged.
