Matt was respectful, knowledgeable and very professional throughout his inspection. He could have told me I needed to do all sorts of things to fix my issues, instead he explained what was going on, told me that they don't do what I needed to get done and referred me to someone that could help. That type of care, honesty and concern are what's missing from many businesses in 2025. It's tough to know who you can trust in these days but I can tell this company operates with a high level of integrity. It's obvious to me they have a heart to serve not just the Denver community but to understand (and have sympathy for) the despair/ stress that comes to homeowners that have foundational issues in their home. Highly recommend.

I would not recommend Liftech based on my experience. The biggest concerns were the lack of proper…read moresubgrade preparation, the lack of transparency, and the difficulty getting clear, consistent answers throughout the process. I specifically chose and paid extra for high early cement because my goal was to regain access to my garage parking as soon as possible. I expected clear guidance on the product's performance and realistic timelines. Instead, I received conflicting information ranging from not being able to walk on the concrete for 48 hours to not being able to park on it for anywhere from 2-10 days. When I asked for clarification, the responses were vague. Liftech's production manager stated, "There are no specific specs for high early since it is mixed with concrete at the plant," and also said, "There is varying information because no concrete is created equally." I would expect concrete professionals and concrete plants to have more consistent information regarding the product being installed. Another major concern was the subgrade preparation. Liftech subcontracted the concrete work, and when the crew arrived, they did not even have a compactor onsite. I asked the workers if they planned to compact the subgrade, and based on their responses and actions, it did not appear that proper compaction was part of their plan until I contacted their Project Manager and requested that a compactor be brought to the site. A video documenting the work can be viewed here: https://youtu.be/YBubb-Wx-ac. In the video, it appears that only about 50% of the area was properly compacted, with some areas not compacted at all. The subbase also does not appear to have been watered down as part of the preparation process. The video speaks for itself regarding the preparation that was completed before the concrete was poured. For a project of this size and cost, I expected better communication, transparency, and attention to detail. Unfortunately, my experience left me questioning both the workmanship and the information provided throughout the process.

Susan was great in reviewing any and all the structural issues with the home we were purchasing…read more Having that information was crucial before buying. I highly recommend this company!

When I was purchasing my home, my general inspector noted various foundation issues in his report,…read moreand recommended that I have a structural engineer come and inspect as well. I raised this as an inspection objection, and the seller decided to hire Susan to come out and inspect. She refuted and confirmed different issues raised by the general inspector, and then the seller collected quotes for the work she recommended, and gave me a concession for that work -- about $8k. Fast forward to 7.5 years later when I was selling the home -- the buyers decided to have Susan McGourty come back out. She told them that the foundation work was not performed properly, and gave them a verbal estimate of $50k in repairs for the house, apparently without giving them any written report, which they said that she would charge for if we wanted it. We got the buyer's permission to speak with her, and she acknowledged that the original work was not done properly, saying that she knew the mason who performed the work, and that he does "good work" but that he just wasn't the right person for the job. I asked her why she quoted over 5 times the original repair cost, and she acknowledged that there were additional issues raised. I asked why she did not raised those issues 7.5 years ago, surely they weren't knew, and she became flippant at this point, saying that "I was only hired to address the issues the general inspector raised". When I objected saying that despite the seller commissioning her, it was my general inspector's report, and I'd been living there for 7.5 years with these issues, she cut me off and said simply "I work for the people who are paying me, just like you." Ma'am, you don't know me. I'm an engineer too, and actually, the customers who I work for and the people who pay me are entirely different individuals, as is the case for probably the majority of the country. But more importantly, as a PE, you should know that your obligations are to the safety, health, and welfare of the public and persons who will be impacted by the work you're performing. I was absolutely shocked at her candor and unprofessional conduct. DO NOT RECOMMEND.
