EverLast Windows and SunHouse in Stamford, CT

EverLast Windows and SunHouse in Stamford, CT

EverLast Windows and SunHouse in Stamford, CT EverLast Windows and SunHouse in Stamford, CT

This Stamford home had windows that were clearly insufficient. The windows could not let in any light because of the overgrown grass. Not only did the basement lack natural light, but it also let in a lot of moisture and air that made the area uncomfortable. The homeowner wanted a solution so he decided to call Connecticut Basement System.  

The solution for this basement was to install EverLast windows paired with a SunHouse window well. The EverLast window has a durable vinyl frame that will not rust, rot, corrode, or need to be repainted. These windows will also prevent heat loss with its Low-E double-paned glass panes. Basement windows are usually located below ground just like this Stamford one. Dirt, debris, water, pests and even plants that take root in the well’s dirt floor would block the beautiful new EverLast window. A SunHouse window well was installed to prevent any disturbances and will also let in lots of sunlight into the basement with the well’s light color and curved form. 

The difference is incredible and the homeowner was very happy with the results. Now, his basement is more comfortable and the area is brighter and more inviting!

To be stable, strong and level, the floor above a crawl space requires solid mid-span support that's usually provided by a post-and-beam assembly. But beams are often undersized, and many contractors use wooden posts that can rot, shift and settle. When this happens, floor joists sag and other structural problems occur. The SmartJack system is a foundation repair product that provides a permanent solution to these problems.

Job Stories From Stamford, CT
WaterGuard System in Stamford, CT

This Stamford home would frequently experience a wet basement every time it rained. The water was damaging their storage items and leaving a musty odor. The homeowner was frustrated and decided to find a solution with Connecticut Basement Systems.  

On the day of the appointment, Sales Representative Steve Godbout arrived at the home to inspect the basement. He identified the problem and knew the perfect solution. He recommended a full perimeter drainage system (WaterGuard System) that would internally collect the excess water and channel it to a sump pump. From there, the water in the sump pump system will discharge the water away from the home. This will ensure to keep the basement waterproofed. The homeowner was impressed with the system and knew that this is exactly what his basement needed to keep dry.

On the day of production, Foreman Krzys Wilk and his team installed the WaterGuard system professionally and efficiently. They first had to excavate the perimeter of the floors to be able to have a place the system. Once the system is placed internally, it is back filled with gravel and then sealed up with cement. This homeowner decided to have a Super sump pump installed and CleanSpace liner, which will help prevent air and moisture from entering and this will help eliminate the musty odor. Once everything was installed, the basement was transformed and waterproofed! The homeowner was impressed and happy that he found a permanent solution.

WaterGuard Keeps Home Dry in Stamford, CT

Griffin H. is a loyal and longtime customer that first used Connecticut Basement Systems more than 20 years ago. When he purchased a second home this year, and found that his basement had a water problem, he knew exactly who to call.

The same week he spoke to Connecticut Basement Systems, Joe met with Griffin at his Stamford home. He recommended the Waterguard interior drainage system, along with a Trench Drain drainage channel, which would prevent the water from getting back into areas it doesn’t belong. When Marcio and his crew arrived at the house, they quickly and successfully installed the systems, along with an alarm to alert Griffin of any further issues. They further protected his property with the usage of a Lawnscape outlet in the backyard, which can be easily cleared by the homeowner. 

A longtime customer like Griffin knows that when waterproofing a basement, a homeowner needs the expertise and permanent solutions that Connecticut Basement Systems provides to keep his home dry for many years to come!

Waterproof First Before Finishing Your Stamford, CT Basement

After two major storms brought unwanted water into Al Y.’s basement, he was ready for a long term solution.  Beyond just waterproofing, he was looking to turn the unfinished basement in his Stamford home into a usable space.  He researched companies online and contacted Connecticut Basement Systems for an estimate.  

Soon after, Mike arrived at his house and discussed his interest in transforming his basement into a family room.  First though, Al needed to take care of the water issue once and for all.  Sid Avis and his crew installed 60 feet of DryTrak, a SuperSump sump pump system, along with a WaterWatch alarm, and the IceGuard system as well.  That way, water would stay out not only when it rained, but when it snowed as well.  

With the basement now completely protected, Al is ready to begin the process to refinish his basement through Connecticut Basement Systems so that he can turn his formerly wet and unfinished basement into a room the entire family can enjoy.

Water Seepage into Stamford, CT Basement

When Tony M. found cracks in his basement walls, identifying that as the source of his water woes, he headed online to research companies that could help him.  He came across Connecticut Basement Systems and sent an email explaining his issue.  Waterproofing specialist Tarn Granucci visited him soon after and came up with a plan to keep the water out.

In just one day, Cisco and his crew used the FlexiSpan Foundation Wall Crack Repair System, and installed a TripleSafe sump pump.  A few months later, Tony noticed another issue where water was coming up through the basement floor.  He called Connecticut Basement Systems again, this time for a complete and permanent solution.  A second sump pump, along with the WaterGuard interior drainage system and a LawnScape outlet in his yard, took care of the problem.  

On top of waterproofing Tony’s basement, Connecticut Basement Systems also tested and sealed the entire area for radon.  Tony’s basement is no longer a source of stress and is instead, a dry and safe space to be in.

Waterproofing unfinished basement
Project Location: Stamford, CT
During Ida we had water seep into our basement (about 1 - 2 inches of water - not a large amount). However, we had never had that happened before. We were able to wet-dry vac it up and dry it out. However, it damaged the wood floor so we want to re-do the area, but ensure that we do any necessary water-proofing, mold-mitigation, etc. before we undertake a renovation.
