New build mastic in Ardrossan
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. Common call-outs are for sealant work across a run of new homes and gaps behind new kitchen upstands, across kitchens, show homes and plot handovers.
Many newer homes in Scotland are timber-framed and settle as they dry out, which shows as gaps at skirtings and floor joints. In older homes, timber floors move through the year too.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

What the job involves on each surface
Windows and doors
External mastic around new windows and doors is sometimes rushed or missed. We reseal it with a weatherproof, flexible sealant.
Skirting and floors
New homes often develop a gap between skirting and floor. We seal it with a flexible sealant that copes with the movement.
The process
Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes anything from a few hours to several days, depending on the number of plots, depending on the size of the job. For a place like Ardrossan, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Let us know about parking restrictions
- Clear the area around the work

Related advice
Why deal with it now?
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Dealing with it early keeps the damage away from ceilings, floors and finishes. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.

Signs you need new build mastic in Ardrossan
Sealant is often one of the last jobs before handover. Dusty, unprimed joints are common, so the bead never bonds properly.
These are the problems we’re asked about most:
- Smeared, uneven beads picked up at snagging
- Gaps opening as the house dries out and settles
- Sealant work across a run of new homes
- Kitchen sealant that has pulled off the wall
For new homes near Ardrossan Town station, it’s worth checking the sealant early, while snags are still fresh.
Before you book anyone
- How the joint is cleaned and prepared
- How long the guarantee is
- Which colour the sealant will be
- What product goes in the joint
Can I do it myself?
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, and the work is guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Ardrossan questions
Is Ardrossan within the area you cover?
Yes, Ardrossan is covered. We work across all of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is Ardrossan in your area for new build mastic?
Yes. Our work covers the whole of Scotland, and Ardrossan is part of that. Just email us at info@mrmastic.co.uk with a few details of the job.
What colour sealant will you use?
We use white, clear or a colour to suit the finishes. Tell us what you’d like when you get a quote.
Can new sealant go on top of the old bead?
No. Over-sealing traps mould and water and soon fails. We remove every bit of the old bead before resealing.
Should I go to my builder first?
Your builder, if you are still in their snagging or warranty period. After that, or if their repair keeps failing, we can do it and our work is guaranteed for a year.
Should I wait before resealing?
It depends on whether water is getting through. A leaking shower or bath seal should be redone right away, but cosmetic gaps can wait for movement to slow.
Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
Is it worth trying it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
New homes and floors in Ardrossan
Ardrossan is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. 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.
Around Ardrossan, as everywhere, new build mastic is only as good as the preparation behind it.

Aftercare tips
So the new joints stay in good condition:
- Act quickly if a seal starts to leak
- Ventilate bathrooms well, especially in the first year
- Clean sealant with mild detergent, not abrasives
- Record problems with dated pictures
Leave the sealant for the cure time we give you before showering or bathing. Silicone is normally left for about a day before water reaches them.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant and the new finishes intact.
