"I was so happy with the work done in my home. Tyler was very easy to communicate with throughout the whole process. Everyone on the Kennedy construction team was very polite and ensured that the work they did would not be finished until we as the customer were happy. Overall I would recommend them to anyone for all their home improvement needs!"

"New walls were built using paneling that matched existing paneling.  I had asked for a 3-foot-high box with removable or hinged lid to be built around the sump pump to keep the cat from playing with it; Jamie recommend a closet instead of a box, which was acceptable to me, and will prove to be a better choice when I have the sump pump discharge rerouted away from sanitary sewer.
Sump pump failed overnight during construction.  I had not moved in yet, so I was glad that the workers altered me.  With my authorization they had a new sump pump installed, removed the soaked carpet, and ran dehumidifiers to dry out the basement.
One door was installed opening opposite my request, but this was too minor a detail to ask for a correction.
New doors and trim were stained and varnished, and all messes were cleaned up completely.  Very happy with the work.  Solar tube (skylight) in bathroom is wonderful!"

"Amanda was really very good!  At first I was very skeptical, thinking why did I pay money to just speak with someone on the phone about my kitchen remodel project... but after just a few minutes of her addressing some of the issues/questions I emailed to her earlier, I knew it was worth it.  It was very clear that she knew her business and she gave me several ideas that I had not even thought about.  I told her that I would definitely recommend her to friends and I will very likely use her again myself for my next home project!

Basement Remodel questions, answered by experts

The best type of basement ventilation system depends on your budget, the moisture in your basement’s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.

Building a bar in the basement will likely add value to your home, although it’s unlikely that you’ll see a significant return on investment (ROI) unless you plan on using the space for you and your guests. If you think you’ll use the area frequently, though, it’s probably worth the investment, and you should see a bump in value if or when you sell your property.

A finished basement must have a heat and electrical supply with an entrance that meets building code requirements, such as a stairwell to the home's main living space. It often must include finished walls, ceilings, and floors. If the finished basement includes a bedroom, it should have a heat source, an egress window, and a closet.

Remodeling, as opposed to finishing, means altering an already finished basement by adding a bathroom, bedroom, or living area.

Whether it’s more affordable to gut a house than build a new one depends on the markets where you'd be buying and selling. However, it’s usually less expensive to renovate a home than to build new construction. 

Most homeowners pay between $100,000 and $200,000 for demolition and remodeling costs, whereas the average cost to build a new home is between $139,000 and $531,300.

Yes, you can add a bathroom to an unfinished basement, but you’ll want to take proper precautions if doing so. As with any bathroom addition, you’ll need to make sure that it’s approved by local building authorities first. With unfinished basements, you especially need to keep an eye on proper ventilation practices.
