On the whole, I thought they did a pretty good job, but there were some issues. The company tried to fix issues when we brought them up. The work generally was of pretty high quality, especially on the interior of the house. However, they did a rush job finishing the cement that had to be re-poured, and they did a shoddy job- the concrete is not smooth and was damaged (made not smooth) by a tarp that they used to cover it (due to the cold weather and the concrete curing). The top of the seal for the exterior waterproofing also needed to be re-done (which the company did at no cost after we brought it to their attention), and they replaced the original noisy radon fan with a quieter one (also at no cost). The job also took significantly longer than originally promised, and I was told by one of the workers that they should have had more people working on our job.
Description of Work: We had a damp corner of our basement waterproofed, and a radon mitigation system installed. We had the exterior wall of the basement waterproofed, a sump pump installed, and a radon mitigation system installed.

Called complete basements systems about getting my dirt crawlspace sealed off with a vapor barrier. I had a few questions about different methods. The company sent me out a very informative guide book that covered crawlspace issues and how to address them. Dave came to the property to do an on site analysis and was very professional, informative, honest and did not recommend anything that I did not need. I received a very competitive bid and was very happy with the company. An unforeseen financial obligation came up and I had to hold off on the job for now, but will contact complete basement systems to do the job when we are ready.

Well, we were quite conflicted about this review. We found Complete Basement at the Denver Home Show and thought it would be a great way to maximize the use of our otherwise unusable crawl space and cut down on the dust in our home. We called to schedule an estimate, and they were scheduling 2 or 3 weeks out. They then proceeded to call and email us multiple times over the next 3 weeks trying to get us ginned up about how great the company was ... before they had even come out to give us an estimate. We really felt like we were being stalked -- multiples calls and emails each week. Finally we got an estimate ... it was expensive, but the work quality looked excellent. So we scheduled the service, again about 3 weeks out. About 2 weeks later, we were called at 8pm to ask if they could change our appointment and show up at 8am the next morning! We politely declined, since we weren't ready for the work to happen. Then, about 2 days before our scheduled appointment, they called and tried to delay our appointment a few days. Again, we had to decline, because we were scheduled to be out of town. They promised that they would keep our original appointment. The morning of our appointment, they failed to show up. At 10am, we called them, and they said they had to push our appointment back to 1pm. They claimed to have called us, but they didn't. So, we learned that their promise to keep our original appointment just meant that they were going to try to squish two jobs into one day. And we all know how that ends ... our job wasn't completed on the scheduled date. They worked on our basement from 1pm to 8pm but couldn't get the job done. The next morning they did the same thing, coming to our house at 1pm after they had finished their originally scheduled project, and staying until 7pm. It was an annoying way to be treated. Despite all of that hassle, all of the scheduling snafus, all of the stalking by the salespeople at the beginning of the process ... we are actually quite happy about the quality of the work. The plastic liner that they use is very sturdy and very easy to clean, so it has made the crawl space a fantastic clean storage area. The workers were also quite careful in our house and they used a negative air containment process to keep the dust generated during their work to a minimum. The workers were also very polite. We would recommend the process to others ... with the caveat that the sales process is annoyingly overbearing, and the scheduling process is a mess. If you can get past those two negatives, you'll be happy with the final product.
Description of Work: Insulate and cover the walls and dirt floor of our crawl space with a heavy plastic liner to prevent dust from getting into our HVAC system and to enable us to use the crawl space for clean storage.

We made contact with Complete Basement Systems at the home show. A rep came to the house and examined the crawl space. We didn't have any water, mold or structural damage. He measured the space and provided some options and prices. He gave us 2 days to make an order at that price. On the scheduled day, they arrived on time. They removed all of the old insulation, and installed everything in one (long) day. They removed all debris and cleaned up. They came through a window in the basement rather than the house. It looks great, and is a lot easier to move around in the crawlspace for storage
Description of Work: We had Complete Basement Systems install foam insulation and liner(CleanSpace) on the floor of the crawl space and wall insulation panels on the walls of the crawl space to create a sealed

I want the work to be completed as soon as possible. I do not want to hear excuses anymore.
Description of Work: Back in March I had mold in my basement. I called them to have them remediate the area. Signed a contract and had a guy assess the work. The work was done at the end of March but at the time the work was done, I had to leave town. I ended up being out of state for a few months. The agreement was that the work would be completed I paid the first deposit, and then they called me and told me the work was done, and I finished the payment. When I returned, the work was not completed. They have avoided my calls, or not called back after promising to do so. I scheduled an appointment for them to check out the work and they did not show up for that either.

Workmen came at appointed time and did their work in 2 1/2 days. They had to jack-hammer the floor to get to the repair. They replaced the boxes that had to be removed to get to the job and cleaned up afterwards.

They were very aggressive on the solicitation of their business. When it came to the time when they were to do the job, they had minimal communication with the workers which were not english speaking. They were not able to install the piers they tried to charge me more money to do it another way and said it would take additional time to complete. They have to date not submitted the proper paperwork to comply to the building dept requirement for a permit and the work has been done for over a month. I also have not received my paperwork for my warranty.
Description of Work: They installed 4 helical piers.

Overall, the company is very good. Their responsiveness to coming out took 2 weeks as opposed to other companies withing a few days. Their bid was right in the same ballpark as the others so I went with them as they seemed more knowledgeable and freindly. After my appt was set, one of the estimators told me to write him with any questions, so I asked only 3 questions and to this day, he has not yet answered them. I suppose once they have the appt, they don't care as much (?) I can only assume, but that did irk me. The 3 guys that came out were on time and excellent, however, they had already worked their 40 hrs for the week, so were told by the company to leave an hour and 1/2 later (at 2:30pm!) and I was very upset as I had taken off work at 1:00pm on, to get this all done as the estimate said. I called the company and everything was fine. (Hint: Don't book work on Fridays). The guys worked really hard, did a great job and were friendly and considerate.
Description of Work: Had their ''CleanSpace'' system put in my dirt 600+ crawl space under the house. It is an encapsulation system which isolates the home from the earth. It is supposed to reduce the humidity level in the air, which reduces or eliminates mold growth, rot and insects from the crawl space. It is a special thick white plastic with 7 different coatings/layers that they lay on the crawl space after leveling it and taking debri out. It goes up the wall about 1' in the crawl space and about 4' up the wall in the tiny basement area. Looks very light and clean in there now.
