Why act early in Greenock
A hairline gap at a skirting can wait, but water getting through cannot. Not sure whether yours can wait? You can email us at info@mrmastic.co.uk with a few pictures and we will tell you. Scottish weather finds any gap, and in a town like Greenock, failed outside joints soon let damp into walls. Inside, a failed seal around a bath or shower lets water into floors and ceilings.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
What you get with us
- Sealant colour chosen to suit
- Anti-fungal sanitary silicone in wet areas
- 180+ five-star Google reviews
- Arbo and Everbuild products

How we handle new build mastic in Greenock
Snagging sealant properly means taking the failed bead out completely. New silicone will not bond to old silicone, so the joint is cut out, cleaned, dried and resealed. If you’re dealing with frame joints opening as the plaster dries and messy sealant that spoils new finishes, we can help, on show homes, skirting & floors and kitchens alike.
Around Greenock, shops and business units have floor joints that break down under traffic. Sealing them before the edges break up saves a bigger repair.
Your job is guaranteed for a year, as with all our work.

Should I try it myself first?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Work for landlords, hotels and businesses
Letting agents often deal with us directly. Tell us the address, the job and how access works.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
What we do, step by step
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes a few hours for most snagging lists, longer for a run of plots from start to finish. In a Scottish town like Greenock, parking is usually straightforward, though older centres can be tighter. For flats, mention the shared stair or door entry system.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely.
- 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.

What else we do in Greenock
What affects the cost of new build mastic
The price is agreed before any work begins. It takes into account:
- The number of rooms or windows
- Working hours on commercial sites
- The type of sealant required
- Any mould that needs treating
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
What to tell us for a quote
You do not need to know the technical terms. It helps if you can tell us:
- Where the job is, and your postcode
- The rough size of the job
- What’s wrong with the joints now
- If someone has resealed it before
It all starts with a short chat. Describe the problem, the location and the size of the job. When it suits you, email us at info@mrmastic.co.uk.
New homes and floors in Greenock
Greenock is close to the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles.
For new homes near Drumfrochar station, it’s worth checking the sealant early, while snags are still fresh.

Signs you need new build mastic in Greenock
New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. Drying timber shrinks and pulls joints apart.
Common reasons people contact us are:
- Sealant applied over dusty or wet surfaces
- Smeared, uneven beads picked up at snagging
- Cracks appearing as a new home settles
- Leaking shower tray seals in a new home
Around Greenock, as everywhere, new build mastic is only as good as the preparation behind it.
What your quote should include
- Whether the sealant suits the joint
- When the joint can take water or movement
- Whether they’re fully insured
- Whether they seal over old material or remove it
