Poly Lift Colorado fixed our sunken sidewalk slab very efficiently, about three weeks before he…read moreinitially estimated he'd have an opening. I'm leaving this review on multiple sites, because these guys deserve your attention. Overall, my experience with Rich and Poly Lift Colorado was (1) great communication, (2) reasonable and competitive pricing (3) clear explanations of their methods, (4) what results we could expect, and (5) what could -- albeit very unlikely -- go wrong. Day of, the team took great care to avoid sprinkler heads that were within an inch or two of the lifted slab and removed all overflow foam very quickly. Best of all, the port holes are essentially invisible. After some weathering, I'm not sure I'll be able to find them at all. This was a very, very, easy process. Highly recommended.

Where to begin with all the great things about this company? I had several quotes and Polylift had…read morethe best price, customer service, and professionalism. Integrity: Rich was very upfront about what he could do and didn't overpromise, under deliver. He was certain that a certain slab would be pinched and still did his best to lift it because other companies said they could, but stopped when it compromised any damage to the concrete slab. You can trust him to do his best and take care of your home. Communication: He was timely in getting my quote, scheduling, and finishing the job in the agreed time. He shared all the details of the job and what to expect, as well as guided me along the process to assure me. This showed me he is honest and direct. Great value: He had the best price and shared how his pricing model worked so I knew exactly what I was paying for. I didn't get overcharged for unnecessary or extra work. I'm very happy with Polylift and know you would be too if you hire them.

The plans included caissons, structural beams and slab, with void-forms to address problems with expansive soils. Despite coming in a bit behind schedule, the Prostruct plans were in such good shape that there were no go-backs or comments from the Building Dept so that the permit issued quickly and work started back on schedule. Prostruct also then supported the caisson and form inspection with the required "Engineer's' Letter." Thanks Prostruct! Well done!

Good project planners would have postponed, but Liftech took down a section of fence (creating a hazard for our dogs), parked a backhoe in our yard, and damaged our neighbors property in the process. Then it was too wet to work - so this mess sat there for weeks. Once work started, it must have been the practice session for the guy on the backhoe - they ended up damaging our seamless steel siding, requiring replacement of a large section of siding, which caused a delay in project completion. Replacing a basement window with an egress window should've been easy - but the crew tossed the removed window onto our rock landscaping, leaving another hazard for visitors with small children, us, and our dogs.. Despite our patience with them while their heavy equipment was parked on our yard, Liftech was unwilling to wait until our siding repairs were complete for final payment. We explained repeatedly that we were waiting for final invoicing from the siding contractor (by now we were not confident they would reimburse for excess expense for repairs) - but Liftech filed a lien against our house instead of having an adult conversation. Then last fall while doing yard cleanup, we realized that they had left a gap between the foundation wall and base plate of our home - full sized leaves were blowing into our basement. Their response: Not our responsibility - go to Home Depot and fix it yourself. Gee, it seems like after paying them this much money they could've restored the house to a safe, sealed condition. Save yourself some heartache and hire someone else.

Job 1 (foundation). Workers good guys and by appearances competent to do job, as was the materials used. They had to bring in backhoe for our 6 ft foundation (we live on hillside with springs where houses commonly shift)- I checked on work and it seemed sound. However, they ran day behind and we had to leave when they backfilled and finish that part of job. It had rained previous 2-3 nights and basically they left yard in a mess that will necessitate me bringing in a landscaper to repair (i.e. more than the topsoil disruption they put in contract- dirt clods the size of soccer balls 25 ft away from foundation wall). My recommendation- make absolutely sure you are present to see finished job before you let them leave- I would never have approved the mess they left the yard in. Not really their fault as they were moving mud vs dirt, but they should've left it and came back the next week to finish. Job 2 (driveway and front approach leveling). It turned out this was an unachievable outcome & there is still 2.5 inch "trip" edge between driveway and garage floor. They should never has bid the job. We contested the job as a breach of contract since goal of job not even close to achieved. Gen Mgr came out & agreed. On my threat to taking to small claims court, they refunded me most of cost of that job. Again, they were responsive to my concerns & outcome OK in the end as avoided court hassle. Lesson here: think about what they are proposing is even possible before agreeing to it. The suggestion is that the job solicitors are working on a commission. If you doubt it can be done, it probably can't- have them describe EXACTLY how they will achieve the proposed outcome. Again, no problem whatsoever with the employees- all did their jobs well.
