Leaky Homes

The founders of Flashclad Ltd and Flashman Flashing Systems have an extensive knowledge of Leaky Homes. Mike Anticich and Steve Hotton the founders and directors of Flashclad and Flashman have been heavily involved in investigating the causes of Leaky Homes for many years. Their expertise and experience extends to redesign, repair and the major work of inventing new and intelligent ways of preventing ongoing leaks in remediated buildings as well as avoiding future leaks in new builds.

Mike Anticich has undertaken in depth investigation and written numerous highly detailed forensic reports on Leaky Homes and buildings for the Government and private clients. He has attended numerous mediations run by government agencies as an expert witness. Steve Hotton has extensive practical and design knowledge. He has advised, redesigned and project managed 50 Leaky Homes and some commercial buildings. Steve provides technical advice and weathertightness detailing covering a wide range of projects to Architects, Designers and remediation specialists throughout NZ. Mike and Steve are qualified builders which mean they have a down to earth practical wisdom in their approach to the original cause of leaky buildings and in their methods to eliminate these same defects when carrying out or advising on the remediation.

Mike and Steve came to the conclusion 15 years ago that there are major endemic problems in weathertightness design, specification and building practice. Weathertightness, which is essentially about correct flashing practice and robust cladding systems is not given the importance or priority weathertightness demands to avoid ongoing leaky building problems. Both men concluded that something needed to be done beyond the painstaking investigation and blame game that is essentially at the core of the litigation process. They decided to do something practical about this national scandal of incompetence and building carelessness.
First, they invented a complete new method of flashing windows and doors with their patented Flashman Window and Door Flashing System. See FLASHINGS.

Second, having redesigned and fully repaired 50 homes as a thorough real life testing ground for their Branz Appraised Flashing Systems, they realised that there is a very limited range of durable, low maintenance, satisfactorily weathertight claddings on the market. They came to the rapid conclusion that they were not happy with any of the popular, mainly paint dependent claddings on the NZ market! As a consequence they have designed and now manufacture, fabricate, market and install a highly innovative range of premium quality, aluminium cladding systems that possesses remarkable weathertightness durability and outstanding aesthetics with very low maintenance requirements. See BevelBord & DualBord

All cladding can and does leak unless properly designed and properly and permanently flashed.

Sadly we are now seeing quite a number of secondary failures in NZ homes that have been inadequately remediated.

High court judge said

 

“the builder failed to maintain proper standards of workmanship” He said “the builder failed to install seals around the windows, allowing water to get in behind the aluminum joinery and penetrate the house`s wooden frame, which then rotted.”

BRANZ BUILD Magazine

A two year consumer awareness campaign launched recently aims to encourage people to consider weathertightness issues when buying, building, renovating and maintaining their homes.
The  most common failures resulting in leaks are cap flashings window flashings cracks in external cladding and cladding too close to the ground.
(Flashclad have isolated other causes of Leaky Homes such as a very heavy and incorrect reliance on sealants to solve most flashing problems and the practice of draining from behind the cladding once it has already penetrated the cladding or junction. This is bad building practice!)

There is a chronic lack of knowledge and experience at all levels in the industry and building failures are the result

Branz recently completed research to understand the movement of air and water in the cavities around windows. This has provided new insight into alternative ways of managing water at the difficult junction between walls and windows

The project was designed to lend scientific support to the window industry in its search for alternatives to the traditional head and sill flashings which can be difficult to install around aluminum-framed windows.
