Condiotti…read more& Associates had my inspection scheduled within days, and provided a very detailed report which will assist me with negotiating during the house inspection period. I received an 18-page report with noted issues and the recommended fix action, as well as pictures of the noted items. This report included a review of the home's foundation, door/window issues, garage floor issues, and the structural integrity of a 2nd level deck and stairs. This was also a very quick-turn request as I had less than a week to provide this report to the sellers. Pricing for inspection and a sealed report were reasonable. Chris Condiotti was very easy to work with, professional, and I highly recommend his services to anyone thinking about purchasing a home in the Denver metro area.

The plans included caissons, structural beams and slab, with void-forms to address problems with expansive soils.

Prostruct also then supported the caisson and form inspection with the required "Engineer's' Letter." Thanks Prostruct! Well done!

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.

I feel we received a fair inspection but had a couple minor questions and were unable to get back in touch with the inspector. Then came the radon. They are a radon mitigation company that advertise a LIFETIME warranty, well that's not even close to true. It just happened that the home they inspected for my client they had installed a mitigation system just over 5 years ago, I sent them their advertising material and there was a whole list of things that you need to do for the warranty to be in place and it was only good for 5 years. This particular house that they installed the mitigation system the warranty wasn't good for a day because of a location of a wall. If you want a big company feel with terrible customer service and a company that doesn't stand behind their service this is the company for you. RUN don't walk. SHAME ON YOU AXIUM.
