"Connecticut Basement Systems prides themselves on their superior customer service, and they really live up to that. Their communication, quality of products and service, and attentiveness to customer needs is unsurpassed. Here are a couple of examples of how they go the extra mile for a satisfied customer: They installed their basement drainage system around my existing heating oil tank, but as I'm planning to convert away from oil this summer, they offered to come back AT NO EXTRA CHARGE once the tank is removed, to reroute the drainage system. Also, I was scheduled for a 3-day project, which included the replacement of some flooring in my basement. On the day the project began, we reconsidered the need for the flooring, and asked if we could cancel that portion of the job. They could not have been more accommodating to that adjustment, and made the change with no questions asked or negative attitude, even though it significantly lowered the price of the project and eliminated a whole day of scheduled work on 2-days' notice. That sort of total customer dedication is rare. I recommend them highly."

"We needed to replace a patch of our living room ceiling due to damage from a water leak upstairs. We contacted C&B, who responded and quoted us a price quickly. The price was fair for a multi-day job, they got it done within a week, and they even helped us repaint the ceiling. Very professional, courteous, and trustworthy. We'd strongly recommend!"

"Vincent Police, the owner, started and completed the work as per the schedule. He was on site the majority of the time both supervising his crew and performing the work. He kept me informed on a daily basis and was very helpful explaining the scope of work as it took place for removing the slab in my 2 car garage and pouring a new reinforced slab. The finished product has a professional looking appearance and the crew left a totally cleaned site. I'm very satisfied with the work and i recommend AA Outdoor Services for similar projects.d"

Basement Waterproofing questions, answered by experts

Basements are commonly converted into game rooms. The potential challenges you may run into include controlling moisture, working with low ceilings, limited natural light, and the need for additional electrical or HVAC work. Addressing these issues can add to the total cost, but it ensures a comfortable and functional space.

Roughing in and connecting utilities are the hardest parts of finishing a basement, and they’re the parts we typically don’t recommend doing as a DIY project. Unfortunately, your finishing timeline can be extended by weeks while you wait for contractors and inspectors to install electrical wiring, plumbing lines, and heating/cooling equipment and carry out inspections.

The best ventilation for a crawl space is a fully encapsulated crawl space with its own separate ventilation system. If you go this route, ensure you have the proper crawl space code requirements done and dusted before encapsulating your crawl space with a moisture barrier and installing appliances that may not be up to the proper specs.

Home improvement grants are available for various groups, including individuals with very low-income housing, elderly people, older adults, and veterans. These grants can cover a range of needs, from accessibility modifications to addressing critical issues that may affect a resident's health or safety.

Yes, outside leaks can easily cause damage to your home if you don’t have waterproofing measures in place. Regularly check your property for signs of a leak, ensure your home’s landscaping is at least at a 5% slope, your basement windows are sealed, and you have an aligned gutter system to catch rainwater.
