How we handle new build mastic in Minnigaff
Some new-home owners let the house settle before resealing. For small cosmetic gaps, that’s reasonable, but a seal that is letting water through needs doing now. We work on skirting & floors, bathrooms & en suites and kitchens, and the jobs we see most are skirting joints opening in the first winter and sealant work across a run of new homes.
Work in a place like Minnigaff is planned ahead, journey included. Outdoor plot mastic needs dry weather, but indoor floor and skirting joints can be sealed whatever the forecast.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Aftercare tips
So the new joints stay in good condition:
- Don’t seal over failed sealant yourself
- Avoid scourers and strong chemicals on sealant
- Put sealant faults on your snagging list early
- Open a window or run the fan after bathing
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. Getting it resealed properly, and any movement checked, stops it recurring.
The process
We bring everything the job needs with us, so there’s nothing for you to buy. Once we’ve agreed what’s being done, we protect the area and start. Most jobs take a few hours for most snagging lists, longer for a run of plots. For a place like Minnigaff, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- 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.
- We tool every joint neatly and tell you when each area can be used.
Getting ready for the visit
- Keep children and pets away from the work area
- Tell us about any previous sealing or DIY attempts
- Let us know about stairs, lifts or work at height

Advice
New homes and floors in Minnigaff
Many new homes in Scotland are timber-framed, and as the frame dries and settles, skirting and sealant joints can open up. Minnigaff is in the west of Scotland, which is wetter than the east, which means plot mastic and the sealant in new homes has to cope with a lot of rain.
Around Minnigaff, as everywhere, new build mastic is only as good as the preparation behind it.

Yes. We work across all of Scotland, and Minnigaff is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job.
Will you just run a new bead over the existing one?
No. The old sealant is cut out fully, then clean and prime the joint, and a new bead applied.

Do you work for letting agents?
Yes. We work for homeowners, landlords, letting agents, businesses and hotels.

The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we’ll talk you through it.
What information do you need?
Just the basics: where it is, what you’ve noticed and how we reach it. Then drop us a line at info@mrmastic.co.uk.
Signs you need new build mastic in Minnigaff
Once people move in, baths and trays take weight and bed down. A bath sealed empty drops slightly when filled, straining the joint and can tear.
People generally contact us after spotting something like this:
- Leaking shower tray seals in a new home
- Internal frame sealant that has split
- Skirting joints opening in the first winter
- Cracks appearing as a new home settles
Whether the job is in Minnigaff itself or nearby, the right material for each joint matters as much as a neat finish.
What your quote should include
- The length of the guarantee
- Whether VAT is included
- How the joint is cleaned and prepared
- How much experience the applicator has
What sealant work can’t fix
We’d rather tell you now than do work that won’t last, so these are the limits:
- Broken tiles or a split tray
- Baths and trays that move too much for sealant to cope with
- Plumbing faults behind the sealant
If you are not sure, just drop us a line at info@mrmastic.co.uk and we’ll give you a straight answer.
What we seal
- Skirting & floors
- Windows & doors
- Kitchens
- Show homes
- Plot handovers
- Bathrooms & en suites
How the job changes by surface
Kitchens
Beside the sink, the joint takes water every day. We use a sealant suited to kitchens, food-safe where it’s needed.
Plot handovers
Taking time over preparation reduces return visits. Dust from the build is removed first and primer used where needed.
Why deal with it now?
It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times for the lot. In an older home around Minnigaff, damp from a failed joint can get into timber and plaster.
Doing several joints on one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.
