New build mastic for homes and businesses in Riverside of Blairs
We never seal over a failed new-build bead. Fresh silicone cannot bond to the old layer, so it all comes out before we clean, dry and reseal. Common call-outs are for cracked sealant around new window and door frames and untidy sealant flagged on a snagging list, across windows & doors, show homes and bathrooms & en suites.
New homes in smaller Scottish places are often single plots, self-builds or small developments. Each needs its sealant and floor joints finished as carefully as on a big site.
A 12-month guarantee comes as standard, so you are covered after we’ve gone.

What the job involves on each surface
Skirting and floors
Wet-area floor joints need a flexible seal. They get a flexible, water-resistant sealant.
Plot handovers
We work through plots to your schedule, sealing each room ready for handover. Joints are prepared properly before sealing to keep callbacks down.
How the visit works
On the day, we start by going over the job with you, so you know exactly what we’re doing. We protect the surfaces around the joints before any work begins. The work normally takes anything from a few hours to several days, depending on the number of plots. Outdoor work around Riverside of Blairs depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- 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.
- We check every joint and leave you with the cure times.
How to prepare
- Let us know about stairs, lifts or work at height
- Mention any sign-in or site rules at work premises
- Where the joints are inside, avoid wetting them before we arrive

Related advice
Can I do it myself?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Keeping the joints in good condition
Aftercare is simple:
- Watch for new gaps as the house dries out
- Avoid running a DIY bead over the old one
- Put sealant faults on your snagging list early
- Photograph failed sealant before it’s redone
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it.
Early snagging is easier snagging. Left alone, a small crack can become a leak.
What sealant work can’t fix
To be straight with you, some problems need a different trade:
- Broken tiles or a split tray
- Deciding who is responsible under a builder’s warranty
- A tray or bath that isn’t properly supported, until it’s fixed
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly before booking.

- Sealant work across a run of new homes
- Leaking shower tray seals in a new home
