About our new build mastic in Finnieston

A new house keeps drying out and settling for its first couple of years. Timber shrinks, plaster dries and baths and trays bed down, so sealant that was laid quickly before handover often cracks. If you have joints pulling apart as timber shrinks and shower seals failing in the first year or two, we can put it right, whatever the surface.

Scotland’s cities are still adding new flats and houses, and new-home owners often find sealant snags in the first year or two.

All our work is covered by a 12-month guarantee.

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.

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

New build mastic in Finnieston: local notes

Finnieston 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. Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles.

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

What we’re called out for in Finnieston

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.

Look out for any of the following:

  • Internal frame sealant that has split
  • Worktop and upstand sealant coming away
  • Skirting joints opening in the first winter
  • Beads laid onto grit and dust from the build

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

  • How the surfaces are prepared before sealing
  • How long to leave it before use

How to choose a mastic man

Surface by surface

Show homes

Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish to a tidy standard. Tell us when the home is open so we can plan around it.

Skirting and floors

Wet-area floor joints need a flexible seal. They get a flexible, water-resistant sealant.

What happens if it’s left?

Water getting past a failed seal in a new build reaches walls and floors that are still settling. Resealing promptly protects the new finishes around it. Wind-driven rain gets into any failed joint on the outside of a city building, and in a tall building in Finnieston, damp can travel a long way before it shows.

Combining jobs into one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.

Questions from Finnieston

What guarantee comes with new build mastic in Finnieston?

Can you help a landlord with a rental near Exhibition Centre station?

Yes, rental work is part of what we do. Just email us at info@mrmastic.co.uk and tell us about the property, and we will give you a clear quote.

What do you need from me for a quote?

Where is Mr Mastic based?

We’re based in Crawley, West Sussex, and we work across South East England, London and Scotland.

Can I do it myself?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

Do you remove the old sealant?

Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.

Do you come to Finnieston?

We do. Our applicators work in Finnieston.

How the visit works

Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for most snagging lists, longer for a run of plots. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. In Finnieston, it helps to know the floor, the door entry arrangements and the nearest parking.

  1. We look at why each joint failed, including any movement.
  2. We remove the failed sealant and clean the joints.
  3. Joints are dried and primed where the product calls for it.
  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.

Preparing for the visit

  • Mention any tricky access
  • For business premises, tell us about site rules or sign-in
  • Let us know about parking restrictions

It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. Whenever you are ready, email us at info@mrmastic.co.uk.

Advice

Honest limits

Some problems need a builder, plumber or other trade rather than us:

  • Movement caused by a poorly fitted tray or bath
  • Leaking fittings rather than failed sealant
  • Deciding who is responsible under a builder’s warranty
