"The visit to my home in West Hartford was a nice affair. The technician explained everything. He even mentioned that I had to get a plumber to remove the sink away from the wall, so the work could be done to repair the window and wall area, but I did not hear him mention that I had to pull permits. The problem with this permit pulling issue is that I never initiated the pulling of permits, and this also is a red flag for me. The pulling of a permit should always be done by the contractor who is doing the job. It ensures that the permit pulled is to code. It ensures that the permit pulled follows local ordinance and CT. laws and statutes regarding construction, and that also includes consumer protection mandates in the State of Connecticut. Having me pull the permit to allow the CT. Basement Systems to do the work is a big, red flag, and it can result in my home owner's policy being cancelled if the permits are pulled either after the fact, or the permits pulled do not line up with the inspection process. I can also be fined by the town for pulling permits after the fact too. I've had my furnace replaced. The plumbing company who replaced the furnace followed state law and guidelines. Especially, since funding provided through a loan from a Credit Union chosen by the State of Connecticut ensured that permits were pulled correctly, legally. The same applies to my roof being replaced. The roofing company pulled the permit. Having a customer whom you are charging in excess of $20,000 to pull a permit is putting that customer in legal jeopardy, which is unacceptable. If I sell my house, and I had the work done in my basement, and the permits were pulled by me. The person who bought my house could sue me for an incorrectly pulled permit. How would I answer questions from the town about the technical aspects of the job, which should be handled by the contractor directly? Why introduce another layer of bureaucracy that slows down communication? Have the contractor pull the permit, so that the contractor and the municipality, town or city can communicate directly, and the pulling of the permit is done correctly and legally. How would I know, when the town should be doing an inspection during or while the job is being completed or after the job is completed? This should never be a requirement of the customer to pull the permit for a job to be done. The tech who visited my home mentioned that I had to hire a plumber to move a basement sink, but they did not mention about pulling of permits, but I went and re-read the quote again, and it is at the bottom of the quote page under "Customer Will" that states not only hiring of the plumber but also pulling permits and scheduling inspections. I did not have this job financed by CT. Basement Systems. I, instead, decided to get a home equity loan. If I did not get the home equity loan, then decided to go with CT. Basement Systems financing, then I would be screwed. The best thing I did was slow the process down, seek my own financing, and ask larger, bigger, deeper questions that prevented me from making a mistake by allowing this work to be done."

"Dustin and CCC did wonderful work creating a new bathroom and remodeling a bedroom for our house. What was most positive was Dustin’s energetic interest in the project, dedication to seeing the project through to make it come out with high quality, and persistently spirited good will. There were two aspects that didn’t work quite optimally: (1) The crew took much longer to finish than they promised (the original time was “1-month +” but over two months passed and there were still lingering issues---see below.) If you hire them, I recommend having it written into the contract exactly when it will start and end, including a specification of what the consequences will be if the job isn’t done on time. (2) They didn’t know what to do with our laminated wood floors. They needed to put down protection for the dining room floor which was damaged by the construction traffic, and they had trouble patching and refinishing the floor in the bedroom after removing a wall. When I asked Dustin to address (2), to his credit he was ready to bring in a floor refinishing specialist to fix the issues at a very favorable price to us. At that point, unfortunately, we couldn’t afford the interruption it would cause to have this repair done at that moment. In response, Dustin gave us a discount so we can address these issues with a profession flooring company in the future when we’ll have a good opportunity to vacate the house for this purpose. I recommend that if you need wood floor work done, you make sure there is an agreement in the contract to have somebody with wood floor expertise address that part. In all, Dustin was generous and willing to try to work with us when there were issues. I know that his company has also been generous about helping people who were in need in the past. This is a quality that I particularly admire in a company, so we still feel very positive toward CCC, but I have identified the issues we had in hopes that they won’t be issues for other clients in the future."
