By Barbara
It all went very smoothly and we were very satisfied. Sisco,the supervisor on the job,was very good and if we needed you again we would certainly want him.
By Cheryl
All the positives come with a caveat - it would be hard to recommend a waterproofing company until the next giant storm. My basement typically floods once a year. So we are looking at next spring for the real test.
By Janice
The test is whether my heating/cooling bills will go down. Definitely will let you know. I also enjoyed reading your founder's book which was very informative and easy to read.
By Thomas
The video of a basement refinishing done by Larry Janesky was very compelling and played a big part in my decision to go ahead with the work.
By MARY
PLEASE PLEASE SEND ME A CERTIFICATE OF COMPLETION WHICH I MUST HAVE IN ORDER TO MARKET MY HOUSE & SUBMIT FOR TAX PURPOSES AT SALE. I NEED IT RIGHT AWAY.
By Loan
Thank you Connecticut Basement Systems for being flexible in getting to us in a timely manner and doing a great job.
By nancy
everything went as planned and the staff was efficient, showed up on time. the salesperson (Tom) explained the process thoroughly and the video was very helpful. I called him and he called me right back several times. All in all, a very good experience.
By Tom
They arrived as scheduled and installed as requested. They cleaned up the work site and were polite.
By Robert
From the salesmen (Tom H.) to the installers, it was the best experience I have ever had!
By Yuki
Overall, my experience was excellent and although the price tag was much much higher than I expected to spend it was well worth the money. This is one case where I have to say you get what you pay for in terms of professionalism, organization, superior product and most important for us, your warranty. We are preparing our house for sale and the wet basement was a huge issue and now it is perfectly dry and completely a non-issue as we can point to your product and your warranty.
By Zachary
Your installation crew was excellent and the head installer, I forgot his name, was very professional. They did an excellent job at cleaning up. We're very pleased with the experience and would recommend you to our friends and neighbors.
By Ernie
Better job than I anticipated.
By Venice
They were curious, on time and provided a good service.
By Peter
Vincent was knowledgeable and a pleasure to work with. Even better was your installation crew...Courteous, friendly and helpful. I couldn't be happier.
By Susan
Overall positive experience
By Larry
From the first meeting with Rick and after reading the company literature, I was really looking forward to the installation. I could not be happier with the system, the installation crew and the company representatives. Rick was extremely helpful prior to the installation and Noel and crew were completely professional, polite and painstakingly clean. I chose to install the triple safe pump, well duct and hot water heater protector and now have complete peace of mind. Not long after the system was installed, we had heavy rain and the pump kicked on flawlessly and very quietly. I cannot wait to recommend your company in the future.
By Michael
Just a note for Ray Lecours. Ray was professional from the moment he came into my home till the end of the presentation. His approach was informal and relaxed as well as educational. I would recommend Ray to anyone who would ask about which company I used for my basement waterproofing system.
By Elizabeth
This company knows their work like no other company, and will transform your basement as they say they will. Be prepared for dust to be everywhere in your house after day one---it is a messy job, but well worth it. Your days of a wet basement will soon be OVER for GOOD! Great company all the way around!
By David
On Saturday 10/8/11 I had my sump pump system installed.The results were impressive, and the whole process was unbelievably easy.I feared the installation would be disruptive, messy and chaotic. Instead, it was a clean, controlled process that was incredibly smooth and efficient.Noel and Martine (I believe that was their names) did the job. They were prompt and courteous. I was very impressed by their professionalism andthey should be commended. The electrician, Mr. William Stocker arrived early and did an awesome job wiring things up. He was a huge help as well.The whole installation was a breeze. And I'm really grateful for everyone involved.Thanks again.
By Kathie
The entire process went smoothly. John McArdle, the sales person explained the product clearly and what to expect in the installation process which was on target. The only concern that I had is with the sani dry unit which was not properly sealed according to my plumber and HVAC people - a concern should the waste system back up. I've spoken with Jason in Quality Control who has been helpful.

We bought our home in Hastings with a great deal of moisture in the basement and even spots of pooled water, particularly after the rain.  The water in the basement was almost enough to stop us from purchasing the home.  CT Basements installed French drains and the moisture system and it has made a dramatic difference.  The basement is now largely dry and accordingly it has become a more usable space.  We are grateful for the product/service they provided particularly given the lifetime warranty and knowledge that they are here if the water returns.

Chuck Stofko and Bill Anderson came to our house at no charge and started analyzing our issue.  They even cut into some walls to identify the source of the odor. They quickly identified the problem was coming from the outside, which essentially took the work away from them.  They took the time to discuss our options and even followed up in that they were looking for local providers to help out. I sincerely appreciated the honesty and quick diagnosis. I would absolutely do business with them again

First off, this is long overdue, but we were extremely happy with the work the team did on on our basement. The team was great and working hard to make sure everything was completed on time. Now we have an awesome space downstairs as well as an extra “bedroom”.

Dear Mr. McCarty, I wanted to write to you to let you know what an asset Gary Meglino is to Connecticut Basements.  Gary came out last Monday, April 23 to assess our waterproofing needs and give me an estimate. From the phone call the night before to confirm our appointment to his follow-up call after his visit, every aspect of my interactions with Gary confirmed that Connecticut Basements is a company I would like to give my business to.  He was professional, personable, and informed. I really felt educated after his visit about the products Connecticut Basements offers and what options were available to me. With his presentation of the product samples and videos, I really felt like I knew exactly what I would be getting from the installation. Gary was so patient in entertaining all of my questions and gave thorough answers.  When he sensed that I would be reluctant to do a full-perimeter installation, he quickly adjusted the quote to fit our priorities. Although we are taking some time to see if some exterior modifications will help to alleviate our water problems, if we do decide a waterproofing installation is necessary, based on my interactions with Gary, we would have full confidence in having Connecticut Basements complete the job. Best regards, Carla Moopenn

To Lawrence Janesky, I am writing this email to praise Basement Systems on two fronts. But first let me tell you our story. After living in our new house for the past 4.5 years with hardly a drop of water in our unfinished basement, we discovered water flooding in at a rate of 10 gallons an hour through every part of the basement perimeter. Naturally we were stressed and baffled and called everyone we could think of including plumbers, excavators, roofers, basement specialists etc. One of the many calls we made was to Basement Systems and it was three weeks for a first time estimate appointment. After applying 6 gallons of hydraulic cement we were able to reduce the flood to a few gallons an hour but we were still frantic to find a solution quickly. Due to the wait for an appointment we wrote off your company as one of the contenders for a solution. After having several basement waterproofing companies visit our home, and after giving a deposit to one of them, we read through the Dry Basement Science book you had sent us through the mail. This very well written and descriptive book put a lot of things in perspective for us and gave us a new light on some of the things the other basement companies had said in their presentations. One of the things I especially valued in your book were the concentration on the technology of your solution vs the other companies concentration on how often they were praised and by whom. It was really the receipt of the Dry Basement Science book alone that caused us to reevaluate your company as a contender. We purposely sought your company out at a booth at the Home Expo at Pace University in Pleasantville, NY last weekend to see what you had to say and whether you might be persuaded to come out earlier to visit our home.  At the Home Expo we had the pleasure to meet with Jeff Nelson who was very helpful in his description of your system and your company. Even better, was that Jeff agreed to make a personal visit to our house that same evening, a Sunday night, after the expo was over! This visit combined with Jeff's superb demeanor and knowledge convinced us to choose your company over the company we had already given a deposit to. In addition, we later learned that Jeff was able to give us a very early date to implement the proposed solution. In summary, I would like to praise you for the book you have written, for the willingness to send it through the mail before we had seen anyone from your company, and for retaining excellent staff such as Jeff Nelson. Sincerely, Patrick V.

    Waterproofing Installation in Croton-Hudson, NY

    This old stone foundation basement in Croton on Hudson, New York was looking a little worse for wear. The family living inside of the home was worried about possible flooding of the basement, so they gave us at Connecticut Basement Systems a call to come check it out!

    Our System Design Specialist Vin Orsini quickly came out to check out the basement, and designed a plan for this basement that was sure to keep it water free. He sent foreman Kryz Wilk and his team, and they got right to work. They installed a TripleSafe Sump Pump, a WaterGuard interior drainage system, IceGuard, SaniDry, and CleanSpace Vapor Barrier. The TripleSafe and Waterguard work together to create a safe, waterproofing method for the basement. The water is captured by the WaterGuard drainage system, then directed to the TripleSafe Sump Pump, and directed outward to an exterior discharge line. In order to protect the basement from mold and moisture, we also installed a SaniDry and CleanSpace Vapor Barrier. The SaniDry works as a powerful dehumidifier, with the ability to capture 109 pints of water a day! The CleanSpace Vapor Barrier protects the basement from moisture and vapor, and also works to keep cold drafts in the winter! 

    This family can now rest easy in knowing they have a basement that will not only be dry, but more comfortable! Give us a call TODAY for your free estimate!

    WaterGuard System in Hastings-on-Hudson, NY

    This basement had a constant water problem that would disrupt the functionality of this home. Tired of a wet basement, the homeowner decided to call Connecticut Basement Systems for a permanent solution. 

    The solution to this basement was to install a full perimeter WaterGuard system to prevent water to enter the area. This system is installed around the perimeter of the basement and will collect water internally and channel it to the sump pump. The sump pump will then discharge the water away from the home. CleanSpace liner was also installed on the half wall around the basement to prevent any moisture or water from the coming through the walls. (You can see the liner in the after photo) This is exactly what the homeowner wanted and was pleased with the results!

    CleanSpace, SilverGlo and SaniDry in Hastings on Hudson, NY

    Before, this Hastings on Hudson, NY crawl space was filthy, smelly and had a dirt floor. This combination led to a moist and unhealthy environment which would affect the rest of the home. The homeowner wanted to transfer her crawl space into a dry and healthier area. With this vision in mind, she trusted the experts at Connecticut Basement Systems who special in crawl space issues of all types.  

    Now, this crawl space is transformed into a clean, dry and healthy area! CleanSpace liner was installed on top of the dirt floor which will act as a moisture barrier and give the crawl space a clean finish. SilverGlo insulation was installed on the walls of the crawl space. This 2 inch insulation with a radiant barrier will both insulate and reflect heat back into the crawl space. Lastly, a SaniDry Sedona was installed and placed into the area. This dehumidifier will keep humidity below 55% ensuring that the air quality will be cleaner and healthier. The combination of all of these products created the exact crawl space that this homeowner wanted!

    A customer in Ardsley on Hudson, NY was getting water in their basement and had existing water damage. They called us at Connecticut Basement Systems to find a solution to their problem. Once an appointment was set, it would be time for one of our Sales Consultants, Vin Orsini, to go to the home to estimate the issues and provide a solution. 

    Once a job was proposed it would then be time for one of our Foremen, Cisco Berrios, and his team to get started on the installation. They installed a WaterGuard perimeter drain system below ground to capture any water that might seep in. Then they installed a TripleSafe sump pump that will collect and pump out the water from the home at a safe distance. The crew also installed CleanSpace on the walls to act as a vapor barrier and protect it from any moisture. Now this basement is dry and the homeowner no longer has to worry about water issues!

    ThermalDry and EverLast Transformation in Mount Vernon, NY

    Before, this Mount Vernon, NY home was a drag with its poorly lit area and not very welcoming atmosphere. The homeowners wanted to transform their space into a welcoming, dry area for the whole family to enjoy. They saw our advertisement in the local newspaper and decided to give us a call for a free, no obligation estimate. They were impressed by our products and decided to move forward with the transformation.

    Now, the area is completely transformed to a bright and welcoming space, thanks to the patented products that Total Basement Finishing has to offer. ThermalDry Elite dark walnut flooring was installed which is a glow up from the previous outdated tile. The benefit of the ThermalDry flooring (besides its beauty) is that it is designed to prevent any moisture from seeping through and it is also up to 10 degrees warmer than traditional basement flooring! The walls were also transformed with our EverLast wall panels. These durable panels are also moisture resistant and add a welcoming feel to the area. Two SaniDry Sedonas were also installed to ensure that the humidity stays below 55%. The entire installation was done by our Total Basement Finishing Foreman, Mike Towle, who sure does have a keen craftsman skill. 

    The homeowners are completely thrilled with their basement’s beauty and the added value their home now obtains.

    This Sleepy Hollow, NY home had cracking and bowing walls that was caused from soil expansion. The homeowner was very concerned for the safety of his home and wanted to take care of the problem immediately. After doing some research, he decided to set an appointment with Connecticut Basement Systems to help find him a solution. 

    Glen Kerpchar was the Sales Representative who arrived at the home the day of the appointment. He concluded that in order to fix the bowing of the walls, Carbon Armor would need to be installed. He explained the benefits of the product and the homeowner agreed that this was the best solution and quickly set an appointment for a production date.

    On the day of production, Victor Alves and his crew installed the CarbonArmor. The CarbonArmor is a great product because it stabilizes your home’s foundation walls by using fiber-reinforced polymers which are 10-times stronger than steel. The ArmorLock brackets bind and secure the Carbon Armor straps to the floor joists making it a great solution, non-invasive, and ideal for stabilizing bowing and leaning walls.  

    With the CarbonArmor fully installed, the homeowner now has a peace of mind of the structure of his home!
