About our new build mastic in Gartness
A new build should have a neat, sound bead at every joint. Smeared, patchy or cracked sealant is worth sorting early, before water gets into the floor or walls. We work on show homes, windows & doors and kitchens, and common reasons people get in touch are messy sealant that spoils new finishes and gaps behind new kitchen upstands.
New homes in smaller Scottish places are often single plots, self-builds or small developments. They need their sealant and floor joints finished just as carefully as on a big site.
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.

Quotes for new build mastic in Gartness
For a quick quote, just ask. What matters most is:
- Working hours on commercial sites
- The type of sealant required
- How many rooms, windows or areas are involved
- The number and length of the joints
What it costs depends on the amount of work, how much old material has to come out and access to the work. We give a clear quote before work begins.
What we need to know
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- How many joints, rooms or windows are involved
- What the problem is, such as mould, gaps, leaks or cracking
- Whether it’s a home or a business
- A few photos by email, if you can
We do not publish a price list, as no two jobs are quite the same. Instead, we give you a clear price for your job. To arrange one, drop us a line at info@mrmastic.co.uk.
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Raise failed sealant with the developer while you’re covered
- Do not seal over failed sealant yourself
- Follow the cure time we give you
- Clean sealant with mild detergent, not abrasives
Keep pictures of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
Report failed sealant to the builder while you’re in the snagging period. After that, putting it right may fall to you, so raise it early.
What we do, step by step
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours in a single home. Outdoor work around Gartness 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.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
How to prepare
- Tell us about any water getting in
- Mention any parking rules near the property
- Mention any tricky access
Getting a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.
Related advice
DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

What we are called out for in Gartness
Sealant applied onto damp surfaces doesn’t bond well. On a busy site, joints aren’t always given time to dry first.
The problems people normally mention when they call are:
- Sealant applied over dusty or wet surfaces
- Kitchen sealant that has pulled off the wall
- Second-fix sealing on new plots
- Leaking shower tray seals in a new home
For new homes near Drumgelloch station, it’s worth checking the sealant early, while snags are still fresh.
Questions to ask before you book
- How long to leave it before use
- Whether the sealant suits the joint
- The length of the guarantee
- How the surfaces are prepared before sealing
What the job involves on each surface
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. A proper reseal keeps water in the tray.
Plot handovers
We work through plots to your schedule, sealing each room ready for handover. Each joint is cleaned and primed where needed.
