FAQs for Strone
Is Strone within the area you cover?
Yes, Strone is covered. Our work covers the whole of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
I let a flat near Gourock station. Can you help?
Yes, rental work is part of what we do. Just drop us a line at info@mrmastic.co.uk and tell us about the property, and we’ll send you a clear quote.
Why has my new-build shower seal failed already?
A new house dries and settles for a year or two, and sealant is often applied quickly onto dusty surfaces. Either can make it fail early.
Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can I do it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
When is the best time to reseal in a new build?
That depends on the joint. A leaking shower or bath seal should be redone right away, but cosmetic gaps can wait for movement to slow.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Is there a guarantee?
Yes, always. Each job is guaranteed for twelve months, large or small.
New build mastic in Strone, done properly
For builders and developers, we work through plots to the schedule you give us. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover with a sealant suited to each area. We work on plot handovers, windows & doors and skirting & floors, and common reasons people get in touch are cracked sealant around new window and door frames and gaps behind new kitchen upstands.
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.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

DIY versus a professional finish
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.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Common problems we fix in Strone
The wrong product is sometimes used in the wrong place: caulk where water collects, or a rigid product on a moving joint. Neither lasts long.
Signs it’s time to call us include:
- Skirting joints opening in the first winter
- Frame joints opening as the plaster dries
- New-build shower sealant that has already split
- Gaps opening as the house dries out and settles
Around Strone, as everywhere, new build mastic is only as good as the preparation behind it.

New homes and floors in Strone
Strone is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up.
If you’ve bought a new home near Gourock station, the sealant around baths, showers and frames is worth checking in the first year or two.

Landlord and commercial work in Strone
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
What sealant work can’t fix
Before you book, it’s worth knowing the limits too:
- Movement caused by a poorly fitted tray or bath
- Leaks from pipes, valves or wastes, which need a plumber
- Settlement cracks that need a surveyor
If you are not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer.
Joints and surfaces we work on
- Show homes
- Skirting & floors
- Kitchens
- Bathrooms & en suites
- Plot handovers
- Windows & doors
Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Keep water off fresh sealant until it has cured
- Report sealant problems to your builder during the snagging period
- Don’t seal over failed sealant yourself
- Use the extractor fan every time you shower
Leave the sealant for the cure time we give you before showering or bathing. Silicone is normally left for about a day.
Mould takes hold quickly in sealant that has gaps or lifted edges. Resealing before mould gets in saves a harder job later.
What affects the quote in Strone
Jobs vary more than people expect. What affects the quote:
- How easy the joints are to reach
- Working hours on commercial sites
- The amount of work
- Which sealant suits the joint
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.
Asking for a quote
To help us quote quickly, please include:
- Where the job is, and your postcode
- Pictures of the joints, sent by email
- Any access issues, like height or stairs
- What’s wrong with the joints now
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job, and we will take it from there.
How the visit works
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself usually takes a few hours for most snagging lists, longer for a run of plots, depending on how much there is to do. Outside jobs in Strone need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
Getting ready for the visit
- On commercial sites, let us know about site rules
- Where the joints are inside, avoid wetting them before we arrive
- Keep pets and children clear of the area while we work
