New-build mastic & snagging in Cadder, East Dunbartonshire
Professional new build mastic in and around Cadder, with old sealant always removed completely.
- Shower seals failing in the first year or two
- Untidy sealant flagged on a snagging list
- Skirting joints opening in the first winter
DIY versus a professional finish
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 fails, we can still redo it.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
New build mastic for homes and businesses in Cadder
Across Cadder, we work for both new-home owners and the builders handing those homes over. Whether it’s one en suite or a run of plots, the method is the same: cut out, clean, prime where needed and reseal neatly. We work on windows & doors, skirting & floors and bathrooms & en suites, and the jobs we see most are gaps behind new kitchen upstands and smeared, uneven beads picked up at snagging.
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.
Whatever the size of the job, you get the same one-year guarantee.

Questions from Cadder
Will you come out to Cadder?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for landlords with property near Bishopbriggs station?
Yes, we work for landlords and letting agents. You can drop us a line at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before work begins.
Do you guarantee your work?
Yes, for a year. If anything isn’t right with the work within the year, let us know and we’ll sort it.
Is it worth resealing while the house is still settling?
For failed seals that let water through, the best time is now. Cosmetic gaps can wait until the first year or two of movement has passed.
Why has my new-build shower seal failed already?
Cracking in the first couple of years is common, because the house is drying and settling. Poor preparation at handover adds to it.
What colour sealant will you use?
The colour is chosen to suit the tiles, worktop or frame. Let us know your preference when you ask for a quote.
Where are you based?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
What happens on the day
We keep the work tidy and contained to the area we are working on, so you can carry on as normal. Expect the work to take a few hours for most snagging lists, longer for a run of plots, and we tell you how long to leave it before we go. Somewhere like Cadder may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.

Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Avoid running a DIY bead over the old one
- Photograph failed sealant before it’s redone
- Avoid scourers and strong chemicals on sealant
- Wait for the cure time before using a resealed shower
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
Why act early in Cadder
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Resealing promptly protects the new finishes around it. In an older home around Cadder, damp from a failed joint can get into timber and plaster.
The cost depends on how much there is to do, how much old material has to come out and access to the work. We give a clear quote before any work starts.

A new house holds a lot of water from the build, which takes a year or two to dry out. As it does, timber shrinks and joints open and the sealant has to cope with the movement.
Keep an eye out for any of the following:
- Gaps opening as the house dries out and settles
- Shower seals failing in the first year or two
- Cracked sealant around new window and door frames
- Skirting joints opening in the first winter
If you’ve bought a new home near Bishopbriggs station, the sealant around baths, showers and frames is worth checking in the first year or two.

How the job changes by surface
Kitchens
As a new house dries, worktops and walls shift a little, which opens gaps along the back. We reseal them with a flexible sealant.
Skirting and floors
Where the floor meets a bath panel or kitchen plinth, the joint keeps mop water out. We seal them with a sealant suited to wet areas.
