Whether you are constructing a new home, have purchased one with a problem, or are renting your home, there are times when things go wrong and you need expert help. Even licensed contractors make mistakes, and we can help you navigate disputes by providing expert consultation. 

We were extremely fortunate to have found Stanley Yeskolski ahead of our court appearance versus our general contractor over faulty roofing work.  Stanley exudes professionalism and integrity.  His expertise regarding all aspects of roofing construction, and the thoroughness and technical detail of his supportive written reports and opinions, exceeded all expectation and played a critical role in helping us to prevail with a favorable settlement on our day in court.

moisture inspection

We investigate moisture problems utilizing state-of-the-art equipment to provide a comprehensive review of moisture intrusion causes and effects. Our team will help you understand the problem and recommend an effective course of remediation.

mold inspection

Mold can damage your property and harm your health. IIS can ascertain the causes and extent of mold growth in residential and commercial properties, using a combination of visual inspection, moisture testing, and mold sampling. We will then advise on a proper course of remediation.

exterior building inspections

We provide comprehensive assessment of installation and moisture problems with building envelopes. Our expertise includes all types of exterior finishes, including EIFS, stucco, stone (natural and manufactured), brick, cedar, vinyl, and HardiePlank siding.

roof inspections

A roof is one of the most expensive investments in your home. We can inspect the installation or investigate moisture problems related to all types of roofing materials, including shingles (asphalt, wood, slate, tile, copper, architectural), roll roofing, built-up asphalt roofing, modified bitumen roofing, EPDM and TPO roofing.

Do you know what’s in the air you breathe? IIS conducts indoor air investigations and sampling to evaluate problems related to mold/moisture contamination, allergens, volatile organic compounds (VOCs), infestations, and more. We provide a detailed report of the laboratory analysis.

construction analysis

IIS investigates construction and installation issues, providing failure analysis in situations where installation method, product design, or material defect has led to problems. We also conduct on-site field testing of window and wall components, providing analysis and scope for remediating the problem.
