About our new build mastic in East Mains
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. If you are still within the builder’s snagging or warranty period, tell them first, and if it isn’t put right, get in touch with us. Typical jobs include second-fix sealing on new plots and new-build shower sealant that has already split, on plot handovers, windows & doors and skirting & floors.
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.

What we do, step by step
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. It normally takes a few hours in a single home. For a place like East Mains, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We go through the snagging list or plot schedule and agree the joints to do.
- The old bead comes out in full, with no layer left behind.
- Each joint is cleaned of dust and grit, then primed if required.
- We apply a sealant that suits each joint and tool it to a neat finish.
- We check every joint and tell you how long each needs to cure.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Move anything stored near the joints

Show homes need sealant that looks right from day one. Every bead is neat and coloured to suit the room.
Plot handovers
Send us the schedule and any sealant specification. Sealant work across the plot is covered as agreed.
Aftercare tips
Aftercare is simple:
- Ventilate bathrooms well, especially in the first year
- Do not seal over failed sealant yourself
- Do not wait for the house to settle if water is getting through
- Photograph failed sealant before it’s redone
Leave the sealant for the cure time we give you before showering or bathing. Silicone is usually left for about a day before water reaches them.
Early snagging is easier snagging. Small faults turn into leaks if left in a busy bathroom.
Questions from East Mains

Are you insured?
Yes. We are fully insured for domestic and commercial work.
Do you do commercial work?
Yes. We have worked for hotels, offices and other businesses and we are fully insured.
Will the old sealant be removed?
Yes, every time. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Can you reseal over the builder’s sealant?
No. Sealing over old sealant looks fine for a few weeks, then lifts. All the old sealant comes out before any work starts.
Is there a guarantee?
Yes. Every job comes with a one-year guarantee.
For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we will give you a quote.
DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
What we can’t put right
To be straight with you, some problems need a different trade:
- Disputes or warranty claims with your builder
- Cracking that points to a structural problem
- Leaking fittings rather than failed sealant
If in doubt, drop us a line at info@mrmastic.co.uk and we’ll say what we think.
Surfaces we seal
- Plot handovers
- Skirting & floors
- Kitchens
- Windows & doors
- Bathrooms & en suites

Common problems we fix in East Mains
Later trades and the final clean can damage fresh sealant. If it’s disturbed before curing, the joint can be left weak.
Keep an eye out for these signs:
- Shower seals failing in the first year or two
- Skirting joints opening in the first winter
- Gaps behind new kitchen upstands
- Sealant applied over dusty or wet surfaces
If you’ve bought a new home near East Kilbride station, the sealant around baths, showers and frames is worth checking in the first year or two.
Questions to ask before you book
- Who turns up on the day
- The length of the guarantee
- Whether VAT is included
- How the joint is cleaned and prepared
