I hired Evert to install new air ducts in the basement. He came and did an entire inspection, and walked me through the best options, including not installing the ducts as it would be costly and not efficient. This guy is not about making a buck--he has the customer best interest at heart. I would call him again for any HVAC needs and I would highly recommend him.

David was wonderful to work with. He promptly scheduled an appointment with me for the very next day to accommodate my association's requirement to inspect my HVAC condensate line. He arrived in a timely manner and kept me abreast of his travel plans. He provided a detailed explanation of the work he was about to do and even provided a better explanation than my association offered as to why this inspection was required. He was very thorough, detailed and professional in all respects. His rates were very reasonable. I highly recommend his services.

I would give Leo six stars if that were possible. I needed a significant amount of insulation repaired done at my business within 24 hours and he made it happen. He and his guys did a great job and we passed the inspection. I was lucky to find them.

Mr. Moore was impressively quick with his response times, and cheerfully accommodated our short time line to perform a termite inspection. Easy to work with and highly professional, he is first on our list for any future pest control needs!

Mike inspected my basement and explained to me in both technical terms and laymens terms the cause and effect of mold. He seemed very knowledgeable in this area, and now I have a better understanding of how to prevent future problems! After the inspection, he wrote down everything that I would need to remedy the problem, he could have stiffed me for $1200 but he was so honest that he said that I could take care of this myself! I would definitely recommend this guy for your inspection and he will let you know,the truth!! Rare today!!!

I hired Ben with Certified Building Inspections to complete an inspection and radon test for a home we are trying to purchase. He was extremely responsive to my initial inquiry and was able to complete the inspection to meet my timeline. His pricing was very competitive with other companies I contacted. Upon arrival at the property, he explained how he would complete the inspection (outside/in, top/bottom, left/right) and asked if I had any questions. I felt he was very thorough and explained what he was looking for in each room. He made sure to point out areas needing attention but also highlighted what was done correctly with the house construction. I had the inspection report including pictures the same day and a revised report with the radon results and thermal images when the test was complete. His service also includes follow-up calls if you have maintenance questions while you own the house. Overall, Ben is an extremely genuine person who stands behind his work and I would not hesitate to hire him again.

I used Ray for the first time to perform a maintenance service on my HVAC system which also includes a whole house humidifier and an air purifying system. He responded immediately to my call, was courteous, pleasant and professional. Ray demonstrated a great deal of skill and knowledge. He did a thorough inspection and explained the work he was doing. He also took the time to vacuum out the unit which had begun to accumulate dust. His charge for the service was reasonable. I also appreciated the fact that he was respectful of my time and arrived promptly as scheduled. That meant that I didn't have to wait around for the standard 2 hour window. I plan to call on Ray from now on to service my HVAC unit and I highly recommend him.

Dave was simply fantastic. He did a very through inspection for our HVAC tune up and had very fair pricing. He kept me involved through the entire processes which was great and I never felt pressured to make any decisions. We’ll definitely use him for any future HVAC needs and recommend him to our friends and family.

Ken was great from start to finish. He took the time to talk with me before the inspection and let me know what to expect. Then, he set up an exact appointment (no four-hour window!) and worked with my schedule so I could avoid taking off too much time from work. He was on time to our place and was professional and polite, explaining more about his process and thoroughly checking out the problem. Throughout, he was excellent in his kindness, understanding, and communication. We agreed to two indoor air samples, in addition to the outside control sample. (He even talked us out of another sample as unnecessary!) Best of all, he was very calm and reassuring with my girlfriend, who was highly upset due to her asthma being seriously aggravated by the problem. As he promised, the lab results came back the next day (bad problem), and he had his full report to us the following day. It included an excellent, comprehensive protocol for selecting and hiring a remediation service. Having been through a mold situation three times in three separate places now, I can tell you firsthand how absolutely important it is to get an independent inspector/tester like Unbiased Mold Inspection, which does not do any remediation or anything else. A LOT of companies do it all, which can make their intentions suspect. With Ken and his company, you know you're getting an objective opinion from someone who's not trying to sell you more services.

From the moment they walked into my house for a FREE ESTIMATED which I loved to the last day they completed the project they showed professionalism, punctuality and work ethic. I love the way my whole house look after the mold inspection and removal plus the floor tile and mastic on my basement. I truly RECOMMEND CRISROD for any asbestos or mold project in your house or commercial.

We are selling a home and a home inspection reported moisture within the basement walls. Not 60 seconds after I inquired with Dan (AdvantaClean) he was responding to me. He was on time for the appointment, explained to me exactly what he would do, and then did a complete analysis of the wall (scope, thermal, moisture meter, mold assessment, etc.) He and his team were extremely professional. Although I didn't end up needing any additional work, I'd hire Dan and his team for any future issue in this area of expertise. Additionally, I enjoyed knowing I was providing my business to a veteran.

We asked Jim to do a complete house mold inspection for a house we were under contract to purchase. We were concerned about previous flooding in the basement of the house, and we noticed areas of the garage ceiling that had been exposed to moisture. There was no visible mold. Jim used the latest spore collection methods and equipment, and he employed infrared viewing to inspect hidden spaces. As it turned out, Jim's expertise paid off. We were saved from making a very expensive investment in a house that showed evidence of toxic mold. We can't praise Jim enough. He is a professional educator who guided us through the process and helped us understand the significance of his findings. We would recommend him as a first choice to anyone in the Maryland area who wishes to have peace of mind about his or her home purchase.

While selling my condo, Thomas fixed all the electrical items identified on short notice. He even corrected items wrong on the inspection report and made sure they were up to code.
