"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

Installing a bathroom in a basement isn’t a project for most homeowners. Many parts—plumbing, electricity, and carpentry—go into this project, each requiring expert-level knowledge and tools. One miscalculation can lead to very expensive repairs. Plus, some homeowner’s insurance might not pay for damages caused by a homeowner DIYing this project. You can protect yourself by allowing the pros to complete this job for you. 

Professional remodelers streamline the process, manage permits, and handle renovations efficiently—significantly mitigating risk while maintaining standards.

Adding a bathroom to your basement can increase your home value since homes with multiple bathrooms sell for more. The return on investment (ROI) for a basement bathroom is 50% to 75%. The actual return varies with your home and location. Adding a half bath to your home increases the value by 2.9% while finishing a basement increases the home value by 6.6%.

Common mistakes when finishing basement walls include neglecting proper insulation, insufficient moisture management, and poor ventilation. Not addressing these issues can lead to mold growth, water damage, and discomfort. Additionally, inadequate planning, improper framing, and rushing the project can result in subpar outcomes. 

It's essential to follow best practices, seek professional guidance if needed, and prioritize thoroughness and attention to detail.

Since DIYing a basement remodel isn't typically advised, there are some ways that you can still save money on this project without putting yourself in danger. Some ways to save money on a basement remodel include:

  • Painting walls yourself versus including in the cost of the remodel 

  • Installing light fixtures yourself

  • Choosing prefabricated fixtures, like cabinets, over custom ones

  • Choosing a budget-friendly flooring option, like laminate or vinyl flooring, and add rugs where necessary
