- Leaking shower tray seals in a new home
- Plot mastic for developers ahead of handover
- Joints pulling apart as timber shrinks
Looking after it afterwards
Looking after new joints is easy:
- Act quickly if a seal starts to leak
- Record problems with dated photos
- Don’t seal over failed sealant yourself
- Clean sealant with mild detergent, not abrasives
Keep photos of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.
Don’t let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you so report it promptly.
New build mastic for homes and businesses in Auchenharvie
Dust is the enemy of new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the new bead bonds properly rather than sitting on a layer of grit. Common call-outs are for smeared, uneven beads picked up at snagging and cracked sealant around new window and door frames, across show homes, plot handovers and bathrooms & en suites.
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.
The work is covered for a year after we finish. If anything is not right with it, drop us a line at info@mrmastic.co.uk.

Auchenharvie questions
I let a flat near Saltcoats station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can go on one quote. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.
Do you cover smaller places like Auchenharvie?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us, and we’re fully insured.
Do you use white or clear sealant?
That depends on what the joint meets: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We agree the colour before we start.
Do you remove the old sealant?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Can you do several jobs on one visit?
Yes, we can. More than one area can be quoted together.
Where is Mr Mastic based?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
When is the best time to reseal in a new build?
If the seal has failed and water is getting in, do it now. Small gaps that are just cosmetic can be resealed once movement has slowed.
New build mastic around Auchenharvie
Auchenharvie is within about 1 mile of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, 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.
Around Auchenharvie, as everywhere, new build mastic is only as good as the preparation behind it. For new homes near Saltcoats station, it’s worth checking the sealant early, while snags are still fresh.

Work for landlords, hotels and businesses
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we will quote.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
How it works
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it usually takes a few hours for most snagging lists, longer for a run of plots. Outside jobs in Auchenharvie need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- Each joint is checked for movement before we start.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
Before we arrive
- Mention any parking rules near the property
- Tell us about any water getting in
- Keep children and pets away from the work area

Advice
How the job changes by surface
Kitchens
Beside the sink, the joint takes water every day. A kitchen sealant goes in there suited to the job.
Show homes
Tired or marked sealant in a show home can be renewed. The old bead comes out and a clean new one goes in.
Leave it or put it right?
Small cosmetic gaps can wait for the house to settle, but a leaking seal can’t. Not sure whether yours can wait? You can email us at info@mrmastic.co.uk with a few photos and we’ll tell you. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.

Should I try it myself first?
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.
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.
