About our new build mastic in Paisley
A new build should have a neat, sound bead at every joint. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. If you’re dealing with smeared, uneven beads picked up at snagging and new-build shower sealant that has already split, we can help, on bathrooms & en suites, plot handovers and kitchens alike.
Around Paisley, shops and business units have floor joints that break down under traffic. Sealing them before the edges break up saves a bigger repair.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

How the visit works
We bring everything the job needs with us, so there’s nothing for you to buy. Once we have agreed what’s being done, we protect the area and start. Most jobs take a few hours in a single home. Parking around Paisley is rarely difficult, though older streets in the centre can be tight. For flats, mention the shared stair or door entry system.
- First we work through your snagging list or plot schedule with you.
- Failed or untidy sealant is cut out completely.
- Each joint is cleaned of dust and grit, then primed if required.
- New sealant suited to each joint is applied and tooled neatly.
- We check every joint and tell you how long each needs to cure.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Let us know about stairs, lifts or work at height
- Mention any parking rules near the property

When it isn’t the sealant
Some problems need a builder, plumber or other trade rather than us:
- Disputes or warranty claims with your builder
- Baths and trays that move too much for sealant to cope with
- Leaks from pipes, valves or wastes, which need a plumber
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we will tell you honestly before you book.
What we seal
- Kitchens
- Plot handovers
- Windows & doors
- Skirting & floors
- Bathrooms & en suites
- Show homes
When to call us in Paisley
On many sites, sealant goes on in the final rush before handover. Dusty, unprimed joints are common, and the sealant sits on grit instead of the surface.
Keep an eye out for any of the following:
- Cracked sealant around new window and door frames
- Plot mastic for developers ahead of handover
- Skirting joints opening in the first winter
- New-build shower sealant that has already split
In and around Paisley, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Why deal with it now?
It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times for the lot. If you live in a flat in Paisley, failed sealant can send water to the neighbours below, which turns a small job into a bigger one.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.

Aftercare tips
So the new joints stay in good condition:
- Report sealant problems to your builder during the snagging period
- Wipe joints with warm soapy water
- Photograph failed sealant before it’s redone
- Avoid running a DIY bead over the old one
Do not stand on the bath edge or the lip of the tray while the sealant cures. Report any movement in a bath or tray.
Report failed sealant to the builder while you’re in the snagging period. Once it ends, the repair may be down to you.
What new build mastic looks like in Paisley
Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles. The west of Scotland is wetter than the east, so there’s plenty of rain for plot mastic and the sealant in new homes to keep out.
If you’ve bought a new home near Paisley Canal station, the sealant around baths, showers and frames is worth checking in the first year or two.

Common questions in Paisley
What guarantee comes with new build mastic in Paisley?
Every job comes with our 12-month guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Do you cover Paisley for new build mastic?
Yes. Our work covers the whole of Scotland, and Paisley is part of that. You can send an email to info@mrmastic.co.uk and let us know what needs doing.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures.
Do you take out the old sealant first?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Can you reseal over the builder’s sealant?
No. Over-sealing traps mould and water and soon fails. All the old sealant comes out before work begins.
Are you insured?
Yes. We are fully insured, with over 20 years’ experience in sealant work.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator.
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 painted or coloured to suit.
Kitchens
Sink joints are wet all the time. We use a sealant suited to kitchens suited to the job.
Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
