New build mastic near Shewalton

New build mastic for homes and businesses in Shewalton

Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. In both, preparation makes the difference since hurried prep is behind a lot of new-build failures. We work on bathrooms & en suites, kitchens and plot handovers, and the jobs we see most are cracks appearing as a new home settles and untidy sealant flagged on a snagging list.

Many newer homes in Scotland are timber-framed and settle as they dry out, which shows as gaps at skirtings and floor joints. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.

Our work is backed for twelve months.

How the job changes by surface

Kitchens

Beside the sink, the joint takes water every day. A kitchen sealant goes in there, food-safe where it’s needed.

Plot handovers

We work through plots to your schedule, sealing each room ready for handover. Joints are prepared properly before sealing so the sealant lasts.

Should I try it myself first?

Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

Joints and finishes in Shewalton homes

Shewalton is within about 2 miles of the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. Shewalton is in the west of Scotland, which is wetter than the east, which means plot mastic and the sealant in new homes has to cope with a lot of rain.

Around Shewalton, as everywhere, new build mastic is only as good as the preparation behind it.

Questions from Shewalton

Do you cover smaller places like Shewalton?

Yes, we do. We work across all of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.

I let a flat near Irvine station. Can you help?

Yes, rental work is part of what we do. You can email us at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before we start.

Can you work from my snagging list?

Yes. We often work straight from a snagging list. We agree the sealant items with you before work begins.

Are you fully insured?

Yes. We’re fully insured.

Does someone need to be in?

If the work is inside, we need someone to let us in. Once we have agreed the job, you do not need to watch us work.

What should I tell you?

Tell us what needs doing and where, plus pictures if you have them. We will ask anything else we need to know.

Who should fix failed sealant in a new build?

Start with the builder if you’re in the snagging or warranty period. Once that’s done, or if they will not put it right, we can reseal it properly.

Can I do it myself?

It depends on the job. High-level, external movement and fire-rated joints are professional jobs.

What happens if it’s left?

If you are still in the builder’s snagging or warranty period, ask them to put it right first. If it keeps failing or isn’t dealt with, we can reseal it properly. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.

We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.

What you get with us

  • White, clear, grey or another colour, product permitting
  • Anti-fungal silicone where joints get wet
  • Full insurance on every job
  • An ARBOMaster approved applicator

What we’re called out for in Shewalton

If plaster or screed was still damp when it was sealed, the bond suffers. Site programmes do not always leave time for joints to dry.

Signs it’s time to call us include:

  • New-build shower sealant that has already split
  • Cracked sealant around new window and door frames
  • Beads laid onto grit and dust from the build
  • Cracked caulk along new skirting

For new homes near Irvine station, it’s worth checking the sealant early, while snags are still fresh.

What your quote should include

  • Is the old sealant removed completely?
  • When the joint can take water or movement
  • What happens if the job turns out different
  • How the colour is chosen

How to choose a mastic man

What happens on the day

There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the job takes anything from a few hours to several days, depending on the number of plots for a typical job. Outside jobs in Shewalton need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.

  1. Each joint is checked for movement before any work starts.
  2. Old sealant is cut out and the joints cleaned.
  3. We make sure the joints are dry and prime them if needed.
  4. New sealant goes in, with baths filled first so they’re at their heaviest.
  5. We check every joint and leave you with the cure times.

How to prepare

  • Mention any sign-in or site rules at work premises
  • Tell us if parking is tricky
  • Mention any tricky access
