New build mastic for homes and businesses in Auldgirth
In a new home, every joint should have a clean, even bead. Smeared, patchy or cracked sealant is worth sorting early, before water gets into the floor or walls. If you have gaps behind new kitchen upstands and plot mastic for developers ahead of handover, we can help, on show homes, plot handovers and windows & doors alike.
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.
We stand behind the work with a 12-month guarantee, so you’re covered after we have gone.

When to call us in Auldgirth
Baths and trays settle under load once the home is lived in. A bath sealed empty drops slightly when filled, straining the joint.
If you can see any of these, it’s time to have the joints looked at:
- Cracked caulk along new skirting
- Leaking shower tray seals in a new home
- Sealant applied over dusty or wet surfaces
- Cracks appearing as a new home settles
In and around Auldgirth, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Different surfaces, different methods
Plot handovers
We work through plots to your schedule, sealing each room ready for handover. Each joint is cleaned and primed where needed.
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. We reseal once the old bead is fully out and baths are filled before sealing.
What affects the cost of new build mastic
Your quote is based on your job. We take into account:
- How much there is to do
- The product the joint needs
- Any working-time requirements on site
- Whether old sealant or filler has to be cut out
Doing several joints on one visit usually makes better use of the time than several visits. You will get one clear quote for the whole job.
What to tell us for a quote
When you contact us, it’s useful to know:

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. Around Auldgirth, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.

Should I try it myself first?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
If you’re set on DIY, put the effort into 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.
New build mastic in Auldgirth: local notes
Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles.
Whether the job is in Auldgirth itself or nearby, the right material for each joint matters as much as a neat finish.

Common questions in Auldgirth
Do you cover Auldgirth for new build mastic?
Yes. We work across all of Scotland, and Auldgirth is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Is new build mastic in Auldgirth guaranteed?
Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint.
When is the best time to reseal in a new build?
Where water is getting through, do not wait. Small gaps that are just cosmetic can be resealed once movement has slowed.
Is there any odour?
Some sealants have a smell while they cure, but it fades. Opening a window helps.
I’m a tenant. Can you help?
We are happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
Is it normal for sealant to crack in a new home?
Lots of new homes see sealant crack early, because the house is drying and settling. Rushed application on dusty surfaces makes it worse.

The process
All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we’ve agreed what’s being done, we protect the area and start. It normally takes a few hours for most snagging lists, longer for a run of plots. Outside jobs in Auldgirth need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely down to clean surfaces.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Before we arrive
- Keep pets and children clear of the area while we work
- Mention any parking rules near the property
- Where the joints are inside, avoid wetting them before we arrive
