"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!"

"There aren’t enough words to express how happy we are with Cade and Modern Edge Construction! Cade helped us finish our basement and lay down new flooring on the main level. He was at our house within 24hrs to give us an estimate and started working on the house the very next day! Cade always communicated the plan, was extremely fair with pricing, and took a lot of pride in his work! We have a couple more projects and can’t wait to work with him again! Highly recommend! 😃"

"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 FAQs, answered by experts

Yes. Renovating your basement has a return on investment (ROI) of 75%, meaning your remodel investment will significantly increase the value of your home. Besides the ROI, your family can enjoy a larger, more usable space while you live there. 

The difficulty of adding a basement to an existing house can vary depending on the house’s location, the size of the basement, and the type and condition of the existing foundation. Adding a basement is a job best handled by the pros, so you’ll need to enlist professional help for this project.

The time it takes to finish or remodel a basement can vary significantly, ranging from a few weeks to several months or even up to a year. On average, the construction phase can take four to eight weeks, but the total project time can extend to three or four months when including planning and permits. The timeline depends on several factors, including the basement's size, design complexity, the scope of the work, and your contractor's availability. A more detailed breakdown for an average-sized basement might include: framing (3-5 days), electrical and rough-in plumbing (3-5 days), drywall installation (5 days), flooring (2-3 days), and final touches like painting and trim (about a week). If preliminary work like installing a waterproofing system or addressing structural issues is needed, the timeline could extend to six to twelve months. Factors like difficult access, material transport, and ventilation needs can also add to the project's duration.

Renovations that add functionality or more comfortable floor space generally add the most value when remodeling your home. Attic or basement finishing can add floor space without altering the home's structure, saving you renovation money while adding valuable space. Smaller improvements, such as installing smart-home components or replacing entry doors and windows, also experience high ROIs. 

Joists and beams are both part of the flooring system above your basement, with the beams spanning the length of your home and getting support from vertical posts underneath, and joists usually spanning half the width of your home with no support posts underneath. The floor joists provide even support to the subflooring and flooring above, and they distribute that load to the beams. The beams then distribute that load down through the support posts to the foundation.
