"I've got a 112 year old hose that is pretty solid, but it had a cracked floor joist and part of the flooring wasn't properly supported. I hired Kristian and his team to install a couple of lally columns to support a carrying beam and sister a couple of floor joists. Many contractors wouldn't even return my call because I wasn't looking to complete a huge remodel job, but Kristian came over, gave me a fair verbal estimate on the spot, and worked with me on timing to complete the project. Not only that, but the solution wasn't overly complicated. The job was straightforward, completed exactly as described in the time described, and there was no scope creep. If I ever have a larger need, they'll certainly be my first call. I would highly recommend K&X construction if you need any services that they offer."

"These guys were great! We got turned down by two large companies because our dryer vent was almost at the peak of our roof on the second floor, but these guys took it on. They came out the same day we spoke with them to take a look and draw up a quote and then came back the following day to do the cleaning on our dryer vent and put in a new vent on the house. The previous owners had on the wrong cover which caused most of our issues to begin with. I would recommend them to anyone we know. They were professional and explained out everything."

"Bill came over and looked at my basement gave me a quote. I had 3 other quotes but not from Angie’s List. Bills was the best quote. He also noticed I had a water problem and my sub pump was not working correctly and he recommended Connecticut basement. I also contacted them. Thanks to Bill now I have a new basement and a lifetime warranty from Connecticut basement for my sub pump and water leak. If it wasn’t for Bill my basement would still have water problems."

"Customer Service was by far above expectations. I felt my basement was as important to Pella as it was to me. Also, we were given great recommendations throughout the process. Quality of the work was very good. Only area for improvement was that the upfront estimate had a couple minor misses, and I would have liked the laminate planks to have been laid with 3-4 row repeating pattern rather than a 2 row; but I never made that expectation known upfront. Overall an excellent experience and I highly recommend!"

"My husband and I hired Lasting Strength after a very stressful experience dealing with a previous contractor who did a terrible job remodeling our bathroom--specifically a horrible shower tile job. Adam came to our house to give us an estimate within the week and began work three days later. He was extremely detail-oriented and skilled. He and his associate Danny repaired our bathroom tile work and also did our planned kitchen reno. He did all the carpentry/cabinet work in the kitchen and suggested ideas of how to handle some challenging issues in our kitchen. He executed brilliantly on all these things and left our new kitchen looking exactly as we dreamed it would look. He also recommended a skilled electrician and plumber who we worked with for the other aspects of the kitchen renovation. We were incredibly satisfied with all the work done on our kitchen and bathroom so we asked Adam to repair some rotted wood in our main door entryway area. The wood rot and damage was significantly more extensive than we originally thought, but Adam and Danny did a great job repairing the structural damage and then laid tile over the repaired area. A beautiful tile job, by the way! We couldn't be happier with our home renovation and with our decision to hire Lasting Strength. In addition to being top-knotch professionals, Adam and Danny are also extremely friendly and always willing to go the extra mile for my home. My family will be keeping Adam's number for any future home needs we have. We HIGHLY recommend Lasting Strength."

FAQs for basement remodeling projects in New Canaan, CT

Finishing a basement turns unused square footage into livable space and returns up to 70% of what you spend when you sell your home. Beyond that resale boost, you gain a playroom, home office, or guest suite you can start enjoying right away. That mix of daily comfort and solid return on investment (ROI) makes basement finishing one of the smartest upgrades you can tackle.

In some parts of the country—especially lots on swamps, high water tables, or other wetlands—local codes prohibit basements. Saturated soil puts constant pressure on foundation walls and lets water seep in faster than any sump pump can handle. 

If your property sits on waterlogged ground, building on a slab or crawl space is often safer, more affordable, and code-compliant.

Most basements wrap up in four to eight weeks. Framing takes three to five days, with electrical and plumbing rough-ins following over the next week. Add five days for drywall, two to three for flooring, and another week for paint, trim, and punch-list items. 

Delays can happen if materials run late or your contractor’s calendar is packed, so build in a little cushion when you plan.

Whether a finished basement counts toward your home’s official square footage depends on local rules. Many areas only include below-grade space if it has code-approved egress, fully finished walls, ceilings, and floors, plus consistent heating. 

Check with your local assessor or building department before you start; meeting those standards can affect taxes, appraisals, and resale value.

Building codes require a checklist: dedicated heat and electrical service, a code-approved stairway, and at least one egress window or exterior door. Walls, ceilings, and floors must be fully finished and meet insulation, ventilation, and fire-separation standards. If you add a bedroom, you’ll also need a closet, proper clearances, and safe exits. If you change the layout later, be ready to update the space so every new room still meets today’s code.
