"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.

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. 

Some older homes have toilets in the basement to combat sewage backups. This type of toilet, also known as a Pittsburgh potty, acted as a safety valve over the incoming sewer line. If a line backed up, it would back up into the toilet because it was the lowest fixture in the home, keeping it out of sight and away from the finished areas of the house.

Basement toilets were also used by workers with messy jobs, like those who worked in coal mines or steel mills. This way, they could clean up and avoid tracking dirt through their home.

Yes, adding a walkout basement will usually bump up your property value. Most homeowners prefer walk out basements because the exposed wall that’s level with the ground provides more utility via a ground-level exterior entrance, and they can fit full windows, which adds natural light and ventilation to the basement area. The only exception might be in areas prone to tornadoes, as walkout basements aren’t as safe as regular basements during a tornado, particularly if they include large windows or glass sliding doors.

A finished basement does not always count as square footage, as this varies by state regulations. In areas that allow below-grade spaces to be included in a home's official square footage, the basement must typically meet certain conditions. These conditions often include having a functional egress and being a livable space with flooring, finished walls, and temperature control. To be certain, contact your local assessor to confirm your area's specific policies regarding basement square footage.
