New build mastic for homes and businesses in Whitelees
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. Common call-outs are for gaps opening as the house dries out and settles and gaps behind new kitchen upstands, across skirting & floors, plot handovers and kitchens.
Timber frame is common in newer Scottish homes, and it settles over the first years, so skirting and floor joints can open up. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

How we quote for new build mastic
You will get a clear quote before any work starts. It’s based on:
- Access and height
- Whether old sealant or filler has to be cut out
- The number of rooms or windows
- Mould in or behind the old joints
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before we start.
What to tell us for a quote
What to tell us when you ask for a quote:
- Photos by email, if that’s easy
- The rough size of the job
- The problem you’ve noticed
- Whether it has been sealed before
There’s no standard price list. Instead, your job gets its own clear quote. To get started, send an email to info@mrmastic.co.uk.
DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
The process
When we arrive, we look over the joints with you first, so you know exactly what we are doing. Surfaces next to the work are protected before any work starts. The work usually takes a few hours for most snagging lists, longer for a run of plots. In smaller Scottish places, parking is generally less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Move anything stored near the joints
- Tell us about any previous sealing or DIY attempts

What the job involves on each surface
Skirting and floors
New homes often develop a gap between skirting and floor. A flexible sealant closes it without cracking like caulk.
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.
When something else is needed
New sealant can’t fix everything, and we’d rather say so up front. Sealant won’t put right:
- A tray or bath that is not properly supported, until it’s fixed
- Deciding who is responsible under a builder’s warranty
- Settlement cracks that need a surveyor
If you are not sure, just send an email to info@mrmastic.co.uk and we’ll give you a straight answer.
What we seal
- Windows & doors
- Skirting & floors
- Show homes
- Kitchens
- Bathrooms & en suites
- Plot handovers
Signs you need new build mastic in Whitelees

- Gaps opening as the house dries out and settles
- Sealant that never bonded to the surface
If you’ve bought a new home near Cumbernauld station, the sealant around baths, showers and frames is worth checking in the first year or two.

How to look after the new joints
So the new joints stay in good condition:
- Clean sealant with mild detergent, not abrasives
- Act quickly if a seal starts to leak
- Ventilate bathrooms well, especially in the first year
- Avoid running a DIY bead over the old one
Avoid standing on the rim of the bath or the edge of the tray in the first few weeks. Report any movement in a bath or tray.
Do not let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you.
