About Me

Even the competitors know they can’t compete.

Don’t take our word about Mark’s vast 47 years of experience. Just ask his competitors. Though many other building agencies dislike it when Mark finds faults in their construction, they still recognize his skill. Other builders will even refer to him when they encounter a construction difficulty beyond their level of expertise.

Patti Parlee observes, “The fact that we receive referrals from competitors says a lot about Mark’s presence in the business.”


The Building Consultant evolved out of a professional call to duty after Mark began his own framing and siding business in 1990. Many homeowners were overwhelmed with their home’s poor construction and frustrated with their builder’s attempts to mend the recurring problems. Various builders recognize Mark’s skill and called him for help with widespread damage repair.

The popularity of his services was virtually self-perpetual — taking flight by word of mouth. Recommendations from impressed customers describing Mark’s “great attention to detail”, “prompt responses”, and “highly competent resolutions” resulted in the consulting aspect of his career coming to occupy the majority of his time. Mark created an identity as The Building Consultant in November 2008.


Mark Parlee has been in the construction business since 1976. For 14 years, Mark acquired considerable construction experience and then formed his own company, Parlee Builders, a construction and remodeling company in 1990. He later also formed Crossroad Homes, a new home construction company in 2000.

Now known as The Building Consultant, Mark hasn’t transitioned out of building; he has created an offshoot profile out of demand for his consultation services to builders and homeowners. Mark has built, dismantled, and replaced exteriors on several hundreds of homes, leading to his current knowledge of how the forces of nature affect the building envelope. He has consulted with a diverse client base regarding all sorts of single-family homes, townhomes, apartments, and commercial buildings.

What is the most prevailing piece of evidence attesting to Mark’s reputation? “We have a 100% satisfaction rate with customers,” Patti Parlee confirms. “Mark loves his job.” Every single one of Mark’s clients has seen their frustration dissolved, established trust with the Parlees, and gained a relationship with their family. Having raised five children of his own, Mark empathizes with parents’ concerns for their children’s safety within their own home and finds fulfillment in knowing you and your loved ones are protected and your largest investment secured.

Do you suspect that your home was defectively constructed?  If you are pursuing a lawsuit, need a deposition, or a third party mediator,  Mark Parlee has been trusted to testify as an expert witness in many significant court cases.

Current Consulting Work & Services

We use a style of reporting that includes detailed pictures of the areas of failure in a building envelope, a narrative that explains the failure, references to the building code and manufacturers’ specifications for the products used and required action to remedy. Some of this investigation requires testing and forensics. Invasive forensic work is only done with approval from the client. We have different styles of moisture detection meters that include both scan and probing meters for confirmation of the presence of moisture. We can provide a thermal scan observation if needed. Caution is in order when using and relying solely on infrared technology as it can produce false positives and one must know how to shoot and read the images. This diagnostic consulting service has developed out of a growing demand from homeowners and businesses that are experiencing problems with their structures. Our investigations and reports are hard to argue against as they
present the facts in an easy to understand and very visual form. If needed, we have access to mechanical engineering services, architectural services, and mold testing and diagnosis.

For out of state clients we have developed a systematic approach to consultations using electronic data transfer. While not as close up and detailed as a personal visit, this method still allows some assessment that can steer a project in the right direction. This is especially helpful if there are personnel on the other end that can gather and disseminate the required data for such a consultation.
