"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."

"We were very pleased with the job performed. Helio's team expanded and renovated our small master bathroom. We took out a large closet and converted it into our shower. Once started, they worked quickly and efficiently. We did have a few small hiccups, namely using our garage to cut tiles and mix thinset, which created an exorbitant amount of dust coating my tools, bikes, and anything else that was stored in the garage. We also had an issue with the cleanliness of the home after some of the workers left, however, after we brought it to Helio's attention, he made sure to tell the team to do a better job moving forward. Contract was a little confusing, so I would encourage many questions to clarify things ahead of time such as timeline for selecting certain items, confirming when the next payments are due etc. All in all, we're pleased with the project and how it turned out."

"It went great. No regrets. They did an excellent job, from the initial quote to the final product, which looks great, and matches the rendering he showed us after he surveyed the space, but before he secured the contract. They walked us through the process, delivered in a timely manner, and they made sure the job was complete. I would recommend them."

Basement Remodel questions, answered by experts

In most cases, a contractor will ask you for a deposit that is a percentage of the total cost of your job, but you should never pay in full before work has begun. The up-front cost could be as much as 50%, or you might give a contractor as little as 10% up front. Discuss payment terms with your contractor before they begin the job to avoid surprises.

Lifting a house and adding a basement is one way to add usable square footage. Lifting or jacking a house is a complex process, and it can be expensive, not to mention that you won’t be able to live in your house while it’s lifted, due to safety concerns. Lifting a house should only be done by experienced professionals.

Adding a bathroom to your basement can increase your home value since homes with multiple bathrooms sell for more. The return on investment (ROI) for a basement bathroom is 50% to 75%. The actual return varies with your home and location. Adding a half bath to your home increases the value by 2.9% while finishing a basement increases the home value by 6.6%.

You can paint your ceiling or install a drywall ceiling if the ceiling is unfinished, as they take up less headroom than drop ceilings. 

If there are pipes in the way of ceiling installation, you can do one of two things: reroute the pipes or adjust the installation to fit, which will cost extra.

The best type of basement ventilation system depends on your budget, the moisture in your basement’s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.
