Recommended language related to incorrect installation of adhered masonry stone veneer cladding.

Background: In recent years adhered masonry stone veneer cladding has been used with increased frequency on the exteriors of buildings. In many cases the installation has been found to be improper and not in compliance with the installation instructions of the stone manufacturers. Incorrect installation can result in water penetration, structural damage, and fungal growth. The following language is recommended for use by home inspectors with regard to incorrectly installed adhered masonry stone veneer cladding. The bulleted items should be used as deemed appropriate for the building inspected.

Recommended Language: Adhered masonry stone veneer cladding has been installed on this house. An inspection of the visible components suggests that the stone cladding system may not have been installed in such a way as to prevent water penetration behind the cladding. At the time of the inspection, the following concerns related to the lack of proper detailing and flashing were observed:

  • No visible weep system was noted at the base of the wood frame walls or horizontal transitions.
  • No visible weep system was noted at the tops of window and/or door openings.
  • No visible sealants were noted along seams between the stone cladding and siding, trim, windows, and/or doors.
  • No indication of a flashing and/or weep system was noted where the stone cladding is in contact with roofing materials or along head flashings.
  • Metal lath was visible, indicating that the proper base coats of mortar were not applied prior to installation of the stone cladding.

The lack of proper detailing and flashing is conducive to water penetration behind the stone cladding and possible hidden damage to the home.

Additional concerns related to installation are listed below:

  • Clearances were not maintained between stone cladding and the ground and/or paved surfaces to prevent wicking and frost heave problems.
  • Clearances were not maintained between stone cladding and roofing materials to allow for proper drainage and future roof repairs and/or replacement.

The installation of the stone cladding should be evaluated by a licensed general contractor and repaired as needed to correct any possible water penetration issues and verify that the stone cladding is installed to the specific installation requirements of the stone manufacturer and/or Masonry Veneer Manufacturer’s Association (MVMA). National Concrete Masonry Association.

Please note that because the water resistive barrier, metal lath, and base coat(s) of cement stucco are completely concealed behind the stone cladding, they cannot be evaluated by a visual inspection.

The gas piping system of this home includes corrugated stainless steel tubing (CSST). This flexible gas line system has specific installation requirements related to electrical bonding, designed to reduce the potential for lightning related electrical arcing that can perforate the tubing and result in gas leaks or fires. During the home inspection, the CSST could not be verified to be integrally bonded or to have a bonding attachment. An electrical contractor should be consulted for a complete evaluation of the CSST installation to ensure the presence of an electrical bonding path.

The purpose of this statement is to assist home inspectors with reporting language when decks are supported by attachment to the structure using only a nailed connection.

The deck relies on a nailed attachment to the framing of the home for structural support. A supporting attachment that uses only nails presents a safety hazard due to the potential for corrosion that can jeopardize the deck support and cause the deck to collapse. When a deck is supported by attachment to the structure, specific attachment schedules utilizing a combination of hot-dipped galvanized nails and bolts or approved self-drilling screw fasteners are required to ensure stability and safety. The deck should be repaired by a licensed general contractor, if the repair is beyond the scope of the building code a licensed professional engineer should be consulted.

Exterior Insulation Finish System (EIFS) Non-Draining

This home is clad with a synthetic stucco system known as Exterior Insulating Finish System (EIFS). EIFS was installed before 1996 as a barrier or non-draining system; however, this method has been discontinued due to extensive problems with trapped moisture, often resulting in hidden structural damage. Based on the visible inspection and age of the home, the cladding system was thought to be a barrier or non-draining EIFS. Due to the non-invasive nature of a home inspection, it is not possible evaluate the home for possible moisture issues or damage behind the cladding. The stucco cladding for this home is in need of a complete evaluation by a licensed general contractor or qualified EIFS inspector.

Exterior Insulation Finish System (EIFS) Not Determined

This home is clad with a synthetic stucco system known as Exterior Insulating Finish System (EIFS). EIFS was installed before 1996 as a barrier or non-draining system; however, this method has been discontinued due to extensive problems with trapped moisture, often resulting in hidden structural damage. Revisions to installation requirements mandated the use of weather resistive barriers and drainage plane systems behind the cladding, designed to reduce the potential of trapped moisture and structural damage. At the time of the inspection, it was not possible to determine whether the cladding on this home is the original problematic barrier system or the improved drainage plane system. The stucco cladding for this home is in need of a complete evaluation by a licensed general contractor or qualified EIFS inspector.

Water Penetration and Condensation: Fungi/Mold

Direction Statement for Consumer Protection

When building components have surface discolorations and decay typical of fungal growths, such as mold, mildew, and wood destroying fungi, the home inspection focuses only on moisture concerns and evidence of wood damage. Health issues related to the presence of mold are beyond the scope of the home inspection. If the client has concerns beyond the scope of the home inspection, a certified professional such as an industrial hygienist should be consulted prior to purchasing the home.

1996 to 2010 PEX

The visible plumbing lines in this home are cross-linked polyethylene (PEX) with brass fittings. Evidence of localized low water pressure and or discolored/corroded fittings was noted during the inspection. This could be the result of dezincification of the brass alloy.

Dezincification occurs when zinc leaches from the brass leaving the fittings in a weakened state. As the zinc leaches, it can also form a build-up inside the fitting restricting water flow and ultimately leaving the plumbing system prone to failure. A licensed plumbing contractor should be consulted for a complete evaluation of the plumbing system to determine the significance of this concern and to make necessary repairs.

Polybutylene

This home has a plumbing supply system that uses polybutylene plastic distribution lines and compression band fittings. Even though this plumbing system was installed in many homes from 1978 until mid-1990’s, it is no longer an approved plumbing system due to a history of material failures. The failures were related to improper installation, improper handling, improper storage, and plastic deterioration due to chemical reactions with the water supply. Due to the nature of this latent defect, it was not possible to adequately assess the condition of the plumbing system during the home inspection. A licensed plumbing contractor should be consulted for a complete evaluation of the plumbing system to determine the significance of this concern.
