What the job involves on each surface
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.
Bathrooms and en suites
En suite showers are a common source of leaks into the room below. A proper reseal keeps water in the tray.
About our new build mastic in Quothquan
Building dust is behind a lot of failed new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the new bead bonds properly rather than sitting on a layer of grit. We work on skirting & floors, bathrooms & en suites and windows & doors, and the jobs we see most are gaps opening as the house dries out and settles and second-fix sealing on new plots.
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.
Every job comes with our one-year guarantee, wherever you are in South Lanarkshire.

For anyone letting property in or around Quothquan, jobs at different addresses can go on one quote. Just tell us the addresses and what each one needs.
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Record problems with dated pictures
- Check bath and shower seals every few months as the house settles
- Act quickly if a seal starts to leak
- Open a window or run the fan after bathing
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small and protects the rest of the house.
Quothquan questions
Will you come out to Quothquan?
Yes, Quothquan is covered. We work across all of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Carstairs station?
Yes, we work for letting agents and landlords. Just send an email to info@mrmastic.co.uk and tell us about the property, and we’ll send you a clear quote.
What colour sealant will you use?
It depends on the joint: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We agree the colour before work begins.
What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
How long should I leave it?
Cure times vary by product. Before we leave, we will tell you the cure time.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Should I try DIY first?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
When to call us in Quothquan
If plaster or screed was still damp when it was sealed, the bond suffers. Site programmes do not always leave time for joints to dry.
The problems people normally mention when they call are:
- Cracked caulk along new skirting
- Beads laid onto grit and dust from the build
- Internal frame sealant that has split
- Shower seals failing in the first year or two
For new homes near Carstairs station, it’s worth checking the sealant early, while snags are still fresh.
Questions to ask before you book
- Who does the work, and how experienced they are
- What the cure time is
- Is the old sealant removed completely?
- Whether VAT is included
What happens if it’s left?
It often makes sense to do all the sealant items on a snagging list together. You get one visit and one clear quote for the lot. Around Quothquan, water from a failed joint in an older stone home can soak into timber and plaster.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, email us at info@mrmastic.co.uk for an honest opinion and a quote.
Why book with us
- One-year guarantee on every job
- Quality sealants from Arbo and Everbuild
- Anti-fungal silicone where joints get wet
- An ARBOMaster approved applicator

How the visit works
You don’t need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the job takes a few hours for most snagging lists, longer for a run of plots for a typical job. Outdoor work around Quothquan depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- 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
- Tell us if parking is tricky
- Let us know about stairs, lifts or work at height
- Mention any sign-in or site rules at work premises

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 fails, we can still redo it.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
