Pittsburgh's choice for superior home inspections. President of the Pittsburgh ASHI certified chapter of inspectors. We are a local family owned business that takes pride in helping all people who are buying or selling homes in the Pittsburgh and surrounding area. Michael is HAAG Engineering Residential Certified Roofing Inspector - #201504301. This designation allows for greater experience in roofing inspections and the ability to work with insurance companies for roof damages. Infrared thermal imaging is included with all homes to help ensure we find leaks from the plumbing or roofing systems, overheated electrical issues, or missing insulation. These are all issues not visible in a typical home inspection. We will customize our work to your specific home without conforming or compromising to a franchise type business model or procedures. We work for you and assist in the process of buying or selling your home. Photos are included in your detailed report that has a full summary to help navigate the process of the inspection.

"Michael is the best! We had an AMAZING experience with him as the inspector for our new home. He was so friendly and involved us in the process, answering all of our questions. We learned so much during the inspection appointment. He didn't just point out issues that needed to be addressed immediately, but also showed us some potential problem areas to keep an eye on. Michael stayed available to answer questions that arose after the inspection and was always so quick to respond. The report he provided was so thorough and was invaluable as first-time home buyers. We are so appreciative of Michael's professionalism and expertise, and highly recommend his services!"

We offer 5 years no interest loans (if qualified) and other finance options.

"I supposedly won their contest at the State College Home Show 2022 for $1200 certificate. Rep came out and knew nothing about giving me the prize I won. Should have seen this as red flag. Window and entry door replaced anyway. Like the window. BUT, the door has major air draft coming in down the side and across the bottom. Have been calling repeatedly for 2 months leaving multiple messages- no return call since back in October. Company sent me letter 11/30 and called me that evening trying to get me to hire them to do more work. Assured me they would send someone to correct problem with initial work. Still have not received phone call or service visit from anyone in this company. Don't enter their contests at Home shows- I think they use this as way to get into your home to sell you their company when you haven't really won anything. and don't hire them to do any work. They will not fix any problems!!"

Energy Efficiency Auditing questions, answered by experts

STC (Sound Transmission Class) ratings tell you how well something blocks airborne noise. It’s a single number that sums up how much sound a material, like a window, can stop across regular speech frequencies. The higher the number, the better the sound reduction. A typical single-pane window hovers around STC 25 (where you can hear normal conversations), while well-sealed, double-pane options can push past STC 45 (which blocks out loud speech and most music). Just keep in mind that STC doesn’t cover everything—low rumbles like bass or thunder can sneak through—so pairing methods are always ideal for the most peace and quiet.

Modern windows provide enhanced UV protection, improved heat retention, and cooling efficiency, contributing to overall household energy savings.

Upgrade to double-glazed glass or apply energy-efficient coatings to reduce heat loss and utility costs.

R-value is a measurement that dictates how much resistance an insulation material has against heat flow—or how well it can stop heat from coming and going. A higher R-value, which is attributed to thicker and more dense materials, means the better the insulation performs. There is not one universal recommended value. It depends on climate zones. For example, Alaska, which has a naturally cold and arctic climate, has higher R-value recommendations than the hot and humid Hawaii.

Gas fireplaces use either natural gas or propane—both of which will increase your energy expenses. On average, running a gas fireplace costs $400 to $640 per year; however, these costs can vary significantly depending on the fuel price in your area and the frequency of fireplace use. If you’re looking for a more energy-efficient option, consider switching to an electric fireplace.
