New build mastic near Greengairs

New build mastic in Greengairs

Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. If you are still within the builder’s snagging or warranty period, tell them first. If you have gaps opening as the house dries out and settles and sealant that never bonded to the surface, we can help.

Work in a place like Greengairs is planned ahead, journey included. Outdoor plot mastic needs dry weather, but indoor floor and skirting joints can be sealed whatever the forecast.

Big or small, it’s backed by our 12-month guarantee.

Should I try it myself first?

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

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.

Signs you need new build mastic in Greengairs

Sealant applied onto damp surfaces doesn’t bond well. On a busy site, joints aren’t always given time to dry first.

These are the problems we’re asked about most:

  • Messy sealant that spoils new finishes
  • Plot mastic for developers ahead of handover
  • Sealant applied over dusty or wet surfaces
  • Joints pulling apart as timber shrinks

If you’ve bought a new home near Cumbernauld station, the sealant around baths, showers and frames is worth checking in the first year or two.

Questions to ask before booking

  • Which colour the sealant will be
  • How the surfaces are prepared before sealing
  • Are they insured?
  • How much experience the applicator has

Choosing a sealant specialist

Aftercare tips

Aftercare is simple, and it makes a real difference:

  • Wipe joints with warm soapy water
  • Open a window or run the fan after bathing
  • Don’t seal over failed sealant yourself
  • Get a leaking seal dealt with right away

Keep the bathroom ventilated, especially in the first year. Use the extractor fan or open a window after showers so moisture doesn’t sit on the sealant.

Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant and the new finishes intact.

How the visit works

We bring everything the job needs with us. Once we’ve agreed what’s being done, the area is protected and the work begins. Most jobs take anything from a few hours to several days, depending on the number of plots. Outdoor work around Greengairs depends on the weather, as sealant needs a dry surface, 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 work begins.
  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. The finished joints are checked and the cure times given.

Getting ready for the visit

  • Tell us about access, such as stairs, a lift or high-level joints
  • Keep pets and children clear of the area while we work
  • Where the joints are inside, avoid wetting them before we arrive

What sealant work can’t fix

Honest advice matters more to us than a booking, so here’s what new sealant won’t do:

  • Cracked trays, tiles or worktops
  • Disputes or warranty claims with your builder
  • Leaking fittings rather than failed sealant

If in doubt, drop us a line at info@mrmastic.co.uk and we will say what we think.

What the job involves on each surface

Show homes

We seal show-home bathrooms, kitchens and frames. We will plan around viewing times.

Bathrooms and en suites

What happens if it’s left?

A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Dealing with it early keeps the damage away from ceilings, floors and finishes. In a place like Greengairs, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.

What it costs depends on the amount of work, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.
