Vicinity of Westerly Ln South in Thornwood

I recently purchased this house so I don't have much history to talk to you about. The basement shows signs of previous water damage but tested dry at time of home inspection. There was some normal damnpness that a dehumidifier took care of. However, after yesterday's rain storms I have significant water in in my basement. Not a ton, not even a 1/8 of an inch, but it was wet, and I m in the process of turning it into a kids playroom, so any water is bad. I would appreciate a cost a talk about my options a pricing them. Thank you

Concerned about where water comes into the basement and possible cracks in the foundation.

Vicinity of Whittier Drive in Thornwood

About 6 months ago had water seep in basement after heavy rainfall. With rain past few days I'm seeing for the first time since then rain beginning to seep in again. I've only been in the house less than two years, I personally took up all carpets and removed Sheetrock 4ft and down. I can now see exact areas of vulnerability. Would like to see what a more permanent solution would cost. Thanks

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.

Explanation of proposed job and literature was excellent. The cost is shocking. The financing and the people at Endobank are good as is the available plan.

Making available a low cost cleaning service for preparing the basement for the job and more thorough clean up after, would certainly be advantageous to the customer.

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.

Basement Finishing & Remodeling in Thornwood, NY

Waterproofing your basement prevents outside water from coming in but what if a pipe bursts or the water heater leaks inside the home. A newly finished basement done by your average contractor will mold and rot if there is an internal leak. You'll have to tear out your new basement! We fix this issue.

Our Products Include :

Waterproof, washable, insulated walls
Mold-Resistant, No-Sag suspended ceiling
Modular carpet, tile & faux wood flooring

Energy-efficient, double-paned basement windows
Attractive Sunhouse basement window wells
French, bifold, louvre & six-paneled steel doors

Unlike the average Thornwood contractor we use completely inorganic, waterproof materials. Even if the basement floods your walls and floors will not be damaged by the water. These waterproof products are patented and are built to create an attractive finished basement that lasts a lifetime.

Job Stories From Thornwood, NY

WaterGuard and ThermalDry Flooring in Thornwood, NY

This Thornwood, NY home had a water issue in his basement that prevented him from utilizing the space to its full potential. He also wanted to have a finished area for all to enjoy. After doing his research he decided to trust the experts at Connecticut Basement Systems and schedule a free, no obligation appointment.

On the day of the appointment, Sales Representative Gary Meglino arrived at the home to evaluate the basement. He concluded that the water issue would need to be addressed first. He recommended a WaterGuard system which will collect water internally before it enters the basement. It will then channel the water to the SuperSump that will discharge the water away from the home. This system will keep the basement dry. In addition, Gary suggested to have new flooring and wall restoration done to make the basement dry and enjoyable. After reviewing each product thoroughly, the homeowner decided to follow through with the project.

On the day of installation, Foreman Al Guglielmoni and his crew installed the WaterGuard System and SuperSump pump professionally and efficiently. Once the waterproof system was placed, Foreman Kevon Barnett installed wall restoration and ThermalDry elite pecan flooring. The wall restoration will replace the water damaged walls that were previously in the basement and will resist any mold or mildew growth. The ThermalDry flooring not only looks beautiful, but it is waterproof and warmer compared to traditional concrete flooring. This is exactly what the homeowner had wanted and was pleased with his waterproofed and finished basement!
