New build mastic in Greenock West, done properly
Snagging sealant properly means taking the failed bead out completely. New silicone won’t bond to old silicone, so the joint is cut out, cleaned, dried and resealed. We’re often asked to deal with shower seals failing in the first year or two and untidy sealant flagged on a snagging list, on bathrooms & en suites, show homes and skirting & floors.
Work in a place like Greenock West is planned ahead, journey included. Outdoor plot mastic needs dry weather, but indoor floor and skirting joints can be sealed whatever the forecast.
You’re covered for a year from the day we finish. If there’s a problem with it, please email us at info@mrmastic.co.uk.

When to call us in Greenock West
Not every new-build joint gets the right sealant: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Neither lasts long.
Keep an eye out for these signs:
- Frame joints opening as the plaster dries
- New-build shower sealant that has already split
- Second-fix sealing on new plots
- Cracked caulk along new skirting
In and around Greenock West, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

- Which sealant they’ll use, and why
- How the surfaces are prepared before sealing
- What guarantee comes with the work
When something else is needed
New sealant cannot fix everything, and we’ll tell you before any work starts. Sealant will not put right:
- Leaks from pipes, valves or wastes, which need a plumber
- Settlement cracks that need a surveyor
- Deciding who is responsible under a builder’s warranty
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think.

Why deal with it now?
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 photos. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, 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.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
For landlords and businesses
Landlords and letting agents in Greenock West can book us as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.

What new build mastic looks like in Greenock West
Greenock West 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. Greenock West is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for plot mastic and the sealant in new homes to keep out.
For new homes near Greenock West station, it’s worth checking the sealant early, while snags are still fresh.
