I moved into a place which was built in 1935 and they had put some wood down there but they hadn’t sealed the basement so it was in a pretty nasty condition when I moved in...

Mr. Larry Janesky, Owner Connecticut Basement Systems 33 Progress Avenue Seymour, CT 06483

Re: Connecticut Basement Systems (CBS) Hegermiller Installations – 4 Oakledge Circle and 18 Scribner Ave, Norwalk, CT 06854

Dear Mr. Janesky,

I am writing to compliment you and your team. From my initial inquiry to CBS to the completion of the second installation today, your people were a complete pleasure with whom to work.

Your salesperson, Vin Orsini overcame my significant objections to hiring CBS, starting with the adequacy of the design and ending with your price for the work (which was significantly higher than the competition). What convinced me to work with CBS was Vin’s thorough knowledge not only of your product, but of construction and of the specific challenges of the job. He far surpassed his peers from Vulcan and BudgetDry who gave cursory, inaccurate or incomplete answers to my questions. Over multiple conversations, Vin spent the time necessary to fully understand the project and to thoroughly explain the solution he recommended. He also was available to me through the prolonged scheduling process and through the job completion. He returned calls, text and emails promptly.

Your production coordinator, Jennifer Raccio, was a joy. I had asked for an earlier job date than was called out in the contract. She called and offered me several dates and ultimately the job was completed before the specified contract date. She was unfailingly cheerful and accommodating.

Finally, your construction crew – both times headed by Josh – was fantastic. (They did my daughter’s house at 18 Scribner first, after which I requested them for the job at my house. I am so glad that I did.) The crew called ahead to confirm their arrival time, arrived when scheduled, worked diligently while on the job, and did a splendid job overall at both locations. Their work was neat and professional. Their truck was well organized and clearly reflected their work ethic. They finished ahead of schedule and left both the basement and their path to the
basement cleaner than they found it. Afterward, Josh fully briefed me on the operation of the system and recommended that I call CBS for annual maintenance.

It is not often you encounter such courtesy and professionalism these days and my experience is that the corporate culture has a great deal to do with how your employees relate to the world. My congratulations to you for the business you have created and the people you have chosen for your team.

At this point, my hope is that your system performs as well as your people. I hope to be able to write you again after a few heavy rains and report that all is well.

Very truly yours,

Don Hegermille

Jules L. Sasqua Pond Road

I have had many servicemen come to my home in many, many years but none as nice as Tony who came to service our dehumidifier today.

Fantastic job! The basement is finally dry! Our odd basement configuration in your old house means multiple installations. Both installation jobs were handled beautifully. The 3rd and hopefully final part of the project should be a cake-walk after these 2!

Vicinity of West Rocks Road in Norwalk

Found water in basement lots of it - water is still coming in after cleanup. House is 3.5 years old has not happened in the past. No sump pump but there are cracks on the floor - one specific area has water seeping in. Temporary sump pump set up and it's removing the water as it comes into the basement. Need someone to come out ASAP

Vicinity of Maher Dr in Norwalk

Last year we had three massive rainstorms that resulted in a flooded basement (had to replace carpet, etc.). We are thinking of possibly moving in next year and cannot have potential floods coming in when the rain gets bad.

Vicinity of Pheasant Ln in Norwalk

Sometimes I get water in my basement, although I already have sump pumps that run a lot during this time of year.

Vicinity of Glendenning Street in Norwalk

The previous homeowners built a deck (c. ~1995) and extended the kitchen onto the deck footings, which have since subsided. About three feet of our kitchen now slants down about an inch, and the door to the deck is slightly out of true. I suspect that there are some flashing/water infiltration issues as well. We would like to preserve as much of the kitchen as possible while building a proper foundation underneath the space. Also, we will be replacing the deck once the foundation / floor issue is fixed. Looking to get quotes on the cost and approaches for this project.

Vicinity of Rockmeadow Rd in Norwalk

Want waterproof flooring, concerned about costs

Vicinity of Raymond Terrace in Norwalk

The previous owners put up a temporary support post in the basement that needs to become a permanent one. I think that more support posts are needed around the stairwell area to prevent additional floor sagging/uneven floors.

We have a full, unfinished basement that we are planning on partially finishing over time. While we want to do most of the work ourselves, we would like to look into waterproofing options prior to doing any work.
