What we do, step by step
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for most snagging lists, longer for a run of plots. Parking in city streets around Garnethill can be tight or controlled, so it helps to know about permits or nearby bays. If you’re in a flat, let us know how we get in at the street door.
- 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.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Clear the area around the work
- Tell us about access, such as stairs, a lift or high-level joints

Related advice
New build mastic in Garnethill, done properly
A new house keeps drying out and settling for its first couple of years. Timber dries and shrinks, and baths and trays settle, and sealant applied in a hurry at handover can split. We work on show homes, kitchens and skirting & floors, and the jobs we see most are beads laid onto grit and dust from the build and shower seals failing in the first year or two.
In older Scottish city flats, floors are often timber over joists, so skirting joints open and close through the year. For a flat in Garnethill, a flexible sealant copes with that movement where filler would crack.
There’s a 12-month guarantee on every job, whatever its size.

What new build mastic looks like in Garnethill
The west of Scotland is wetter than the east, which means plot mastic and the sealant in new homes has to cope with a lot of rain. Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles.
For new homes near Charing Cross (Glasgow) station, it’s worth checking the sealant early, while snags are still fresh.

Do you need new build mastic in Garnethill?
New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. As it does, timber shrinks and joints open, and sealant that cannot keep up splits.
The problems people normally mention when they call include:
- Second-fix sealing on new plots
- Smeared, uneven beads picked up at snagging
- Beads laid onto grit and dust from the build
- New-build shower sealant that has already split
Around Garnethill, as everywhere, new build mastic is only as good as the preparation behind it.
Questions to ask before you book
- Who does the work, and how experienced they are
- Whether they’re fully insured
- Whether they seal over old material or remove it
- What happens if they find a problem under the old sealant
DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
FAQs for Garnethill

Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Do you cover Garnethill for new build mastic?
Yes. We work across all of Scotland, and Garnethill is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
I rent my home. Can I book you?
Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
Can you reseal over the builder’s sealant?
No. Over-sealing traps mould and water and soon fails. We remove every bit of the old bead before resealing.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of 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.
Why it’s worth doing now in Garnethill
Resealing everything on a snagging list in one visit is generally simpler than chasing joints one at a time. It’s one visit, one quote and one set of cure times to plan around. Private landlords in Garnethill must meet the Repairing Standard, and damp or leaks can fall short of it, so it’s worth fixing failed sealant before a tenant reports it.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we will go through it with you.
