Monolithic Clad House Repairs Are Different

Correct the defects that let water into your home and decay your timber, with proven repair methods developed specifically for monolithic cladding.

The various types of monolithic cladding each have their own set of typical defects and best ways to address them. Just patching the cracks, re-sealing or painting isn’t usually the answer – in fact repainting just makes it harder for the water from the leak to dry out.

With over twenty years specialist experience in repairing and improving plaster clad homes, Moisture Detection has developed a range of repair methods to resolve the root leaky home problems and make your house dry again.

Our repairs fix key defects such as:

  • Leaking or defecting flashings
  • Decayed timber
  • Untreated timber
  • Leaking windows
  • Cracks
  • High ground lines up to or above the cladding
  • Overflowing Taylor or Klass fascia style gutters
  • No or inadequate head flashings above windows and doors

Unique ‘Proof of Repair’

Moisture Detection is the only company with the tools to find the leaks, fix them, then prove that the repair has worked with Moisture Detection Probes.

  • Find, the leak – either with visual inspection or with moisture detection probes
  • Diagnose, investigate the cause of the leak and recommended repair method,
  • Repair, carry out the repairs
  • Monitor, with Moisture Detection Probes to confirm that the house is drying out.
Examples of Plaster Home Repairs 

Drying and Venting Skirts – for high ground line problems

Many homes were built with the cladding buried into, or just too close to the ground.  This allows moisture to soak up the cladding like blotting paper, wetting the framing.  Because the cladding is fixed hard against the framing, there is no ventilation and the timber stays wet -and goes rotten.

Our moisture probes show which parts of the house are damp or decayed because of this fault. 

Pre-purchase inspectors always report any high ground line issues as a leaky home risk and sales often fall through because of this.

Moisture Detection Company Drying skirts break the connection between the cladding and the ground while simultaneously ventilating the bottom cavity to allow moisture to dry out. 

Window Sill Flashings

Probably the most common leaks we see in plaster clad homes are from the windows. Most of the cladding manufacturers relied on PVC strips to keep out the water and now, 20 years or more later, they are failing.

Our moisture probe installations usually find at least one window leak causing moisture and decay which needs to be resolved before the damage gets worse.

Pre-purchase inspectors will find the leak and report that windows without adequate flashings are a high leaky home weathertightness risk.

Moisture Detection Company have retrofitted hundreds of coloursteel window flashings which fit up behind the window flange and safely direct water out of the house. These are neatly plastered into the jamb and incorporate an obvious out-turn at the ends.

Overflows for Fascia Style Guttering

The Taylor or Klass fascia style guttering was a spectacular failure installed on tens of thousands of homes.  When the guttering overflows, the water runs back into the wall, where it can cause very serious decay problems.  There are often other gutter installation defects causing other leaks.

If you can’t afford to replace your guttering then a low cost option is to have high volume overflows installed at critical locations so that overflows go out of the house instead of into the walls.

Custom Flashings

One of the big contributors to the leaky home scandal was the failure of flashings. This was due to the increasing complexity of houses, the decreasing skill level of the designers and builders, and an over-reliance on sealants, instead of steel and lead, to keep out the water.

Building regulations now recognise that sealants are not sufficient however tens of thousands of homes are left with leaks that are just getting worse. Leaks are happening around roof connections, deck connections, scuppers, internal gutters, chimneys…..

Just one badly formed flashing can result in massive damage (see this webpage for an example).

The leaks from bad flashings can’t hide from Moisture Detection Probes. Then, if resealing is not going to be sufficient, a custom flashing is made to ensure weathertightness.

Pre-purchase inspectors look for, and report on, flashings that are missing, or don’t look properly constructed. House sales fall through because of these defects which can be resolved before going to market.

Stop Decay Without Replacing Timber

The biggest leaky home defects is the untreated or undertreated timber, which decays when it is wet.  This timber should never have been used in the first place however now there is a way to correct this.

RotStop Treatment is injected through small holes in the cladding

  • RotStop, from Moisture Detection Company, puts rot on hold and treats your timber to protect it from decay in the future.
  • Every plaster clad house with untreated timber is at risk and needs RotStop.
  • Identify the areas needing treatment with Mdu Moisture Probes.
  • Treat the rot, then fill up and paint the holes

Please visit our RotStop page for more information.

Improve the Resale Value of Your Plaster Clad Home

Buyers, Pre-Purchase Inspectors and Banks can walk away from your home if leaks and critical design and construction defects aren’t corrected.

Many of the construction techniques used during the leaky homes era are now called ‘Risk Features” and a pre-purchase inspection report will list everythingl that can be seen as well as many that just might be there. Your buyers either walk or drop their offer price.

Identifying and correcting as many of these defects as possible before going to market lets you sell for a fair market price, without buyers walking away.

Correctly diagnosing

Your home is likely to be your largest asset.

Why is it then that we spend more time, energy, and money on cars than we do on our homes?

When you own a Monolithic, or plaster clad home, there are several areas that need extra attention to keep it ship shape.

Here’s a list of some of those repairs that you home will thank you for:

1. Cleaning The Guttering

This is particularly important if you have an internal guttering system. After the autumn leaves have fallen, make sure you clean out the gutters so that the water can flow freely. Failure to do this can have water pouring into the cladding and wetting timber.

2. Overflows on Guttering

An internal gutting system may look nice, however they are no longer sold because of their high failure rates. The internal lip is typically lower than the outside ridge, allowing excess water to build up and overflow inside the house. If you are experiencing this, Moisture Detection can install overflows to re-route the water outside and onto the ground.

3. Drying Skirts

The patented Drying Skirt introduces a cavity and enhanced dryability into a wall without the need for expensive recladding. It can be simply retrofitted onto an existing building to introduce much needed drying and drainage at the base and midfloors of houses. It is sealed onto the existing cladding system and the look is a neat plinth. Coupled with other technologies, it completely does away with the need to reclad vast areas of wall – saving hundreds of thousands of dollars. Retrofitting the Drying Skirt on your building gives you many benefits:

Simple and cost-effective alternative to recladding.
Allows a thorough inspection of bottom timber of walls without the removal of the rest of your cladding system during installation.
Window and door flashing systems remain intact
Eliminates moisture wicking issues caused by absorbent fibre cement and plaster cladding systems that go into the ground
Introduces bottom drainage gaps to the cladding system
Introduces ventilation ducts allowing drying to occur on the cladding behind
Note that if your wall framing has decay or untreated timber, we recommend treating the wall with RotStop before installing a dry skirt.

4. Window Eyebrows

What are Window Eyebrows? They are a stylish water management system for diverting surface water away from vulnerable cladding edges and openings.

Eyebrow Deflectors simply retrofit onto existing window systems, pushing surface water off the wall face before it hits the window, improving the deflection of window systems and protecting the head flashing of sensitive systems.
