Stacey S.

He was extremely thorough. He advocates and looks out for his clients. He does not let the realtor bully him in to clearing something that should not be cleared.

mr carls and another gentleman came right on time on the date of service. they did a thorough walk thru of the entire house from the exterior, attic, and all the levels of the house (3 floors). they found about 6 pages of items that the builder will need to look into, including improper insulation, vents not working properly, water leaks, warped siding, etc... they were very knowledgeable about how everything in the house worked and gave us good advice. although it was pricey, the things they found that should be covered under the 1 year builder's warranty made it worthwhile. i would give them 2 thumbs up.

Phil Carls and Conn O'Neill showed up to do the work and were punctual, friendly, thorough and very pleasant to work with. They took a lot of time to explain to both of us issues that they found as well as things about the house that were in great shape and things we should be happy about. They made sure we understood what they saw, and encouraged us to get involved by touching and getting hands on in some of the items that they discovered. Throughout the inspection, they answered all questions and even answered questions before we asked them! They went as far as eyeballing the outside environment to figure out if there were any concerns in the surrounding area (neighbor's very large tree was angling towards the home and could prove to be disastrous should it fall). Their professionalism, knowledge and demeanor were impeccable and they left us their contact information to call them for any follow up questions we would have. Their pricing even came in lower than a few other shops we located, so that was an added bonus! Highly recommended in every way!

Description of Work
The Carls Group was recommended to us by our realtor, who had previously worked with them on multiple occasions for a home purchase inspection. We bought an older home (35 years old) with a pool and two separate kitchens, so we required a long and thorough inspection of the home. They started with the roof and exterior of the house, the patio, deck, pool, then every single outlet, fixture, smoke detector, window, plumbing, etc. I don't think there was an inch of the home that they did not inspect.

Phillip and Conn were very thorough. They walked us through every step and taught us things we need to know in order to take care of the house. They inspected the house very thoroughly and explained everything to us. They were very professional, friendly, and they even arrived before the designated time. It was a pleasure to see such a professional team work. Phil and Conn were even so kind as to offer their services as we grow with the house. This kind of relationship and commitment is unheard of. I would recommend their services to anyone looking to make a good first investment in their house.

We moved into a new modular constructed home just after the 4th of July. After moving in, we soon noticed a septic smell that seemed to be emanating from the master bath. The same smell was at the corner of the house where the Junction box connecting the electrical sensor from the home to the septic pump chamber located ten yards away. No one. I mean no one could find out the source of the foul septic odor. Our builder called a master plumber to investigate. The master plumber was stumped. The builder had a company conduct a smoke test. Although smoke filled the master bath, the company asserted that it was not a problem. My wife and I scratched our heads, and the service folks just shrugged. Then we contacted Phil Carls. As soon as he hopped out of his truck he had already discovered a few discrepancies with our septic venting system (the vent pipe was too low) and he pointed out that the J-box at the side of the house was not properly covered. He and his assistant then went through the entire piping system up in the attic. Following the pipes along the attic, Phil found a clue: a small chard of broken PVC. He trailed the pipe with his finger until he located the place from where the shard came. A huge hole. He also discovered that the cap of the T-joint was not sealed or capped. Instead joists were resting on the open T-joint. Phil Carls solved the puzzle. He also pointed out other items throughout the home that are not consistent with industry standard and sound construction practices that should be addressed from improper insulation to potential radon problems. We are extremely happy and satisfied with his service.

Phil Carls performed a thorough walk through of our SFH during the home inspection. He conducted a detailed 3 hr inspection ; included Attic, Kitchen/Appliances, Central Heating/AC, Plumbing, Electrical, Roofing, Exterior, Structure, Fireplace, Water Heater, Grounds, Windows/Doors, Gutters/Drainage and much more! He was friendly, professional, and clearly knows what he's doing. He took time to help us evaluate the priority of issues; what were cosmetic defects and what were real safety issues.
