Special shout out to Hunter Lewis, always provided cost effective options for problems, always available for quick questions, timely updates on project progress, polite and patient.

"Would highly recommend Jason and Blue Mountain. We recently used him for a master bedroom and bathroom remodel as well as renovations to our screened in porch. Jason was responsive and communicated with us every step of the way. He met the timeline and deadlines that were set for our projects. Jason and his skilled employees were friendly, courteous and a pleasure to have in our home. Their work was meticulous and they cleaned up every day before leaving our home. We are thrilled with our upgrades and have future projects planned with Jason and Blue Mountain Building."

"My experience working with Basement Gurus, especially Phil Thistle, was fantastic. Phil and the crew were very thoughtful and responsive from the moment I called basement gurus until the moment my installation in my basement was complete. I greatly appreciated how dedicated Phil was in answering my questions and checking in with me regularly about my concerns and how the job was going throughout the entire process. Would definitely recommend basement gurus for your waterproofing needs!"

"Ground up Renovations finished my walk out basement for my mom and step dad to live in. After consulting with 3 other renovating companies, we felt the best about them and they were very fair with price. They were on schedule with everything and it really turned out amazing. If there was ever a question about something he would call and stop by if needed. They are professional yet caring and easy to talk to. We ended up having them back for other projects and estimates and they are now our go-to company."

"Yaniel's Renovation LLC completed remodeling work, including putting in hardwood floors, installing cabinets, vanities, and doors, and interior painting. Francisco and his team worked to ensure that the home improvements were to my liking and that they were suitable down to the very last detail. They remodeled with an eye towards the future maintenance of my home. Rosa was immensely responsive. I am very pleased with the results."

Basement Remodel FAQs, answered by experts

Adding an extension or addition to your home costs more than a loft conversion in all but the rarest cases where the home's structural integrity is lacking. Because a home addition requires a new foundation section or significant structural upgrades to handle a cantilevered portion, the cost compared to almost any loft conversion is significantly greater for the same square footage.

The most challenging part of finishing a basement is addressing moisture control. Basement waterproofing is an essential task that requires a professional’s skills and knowledge. If you don’t properly waterproof your finished basement, it’ll be vulnerable to dampness, water damage, and mold growth. Ensuring proper insulation and ventilation to combat these issues while meeting building codes adds complexity to your remodeling project.

Yes, it is possible to turn a regular basement into a walkout basement. Doing so involves excavating the land around at least one side of your basement foundation, installing retaining walls to create a permanent below-grade area outside your home, and then cutting into the foundation to install an exterior door that leads out to the new space. This is an expensive and time-consuming project, but it can add a lot of value and utility to your home.

In many homes, an unfinished basement is an ideal place for an in-ground pool. The concrete floors, protection against water damage, and access to the ground below your home make this a large contender. Speak with a local basement remodeling contractor to ensure your space is right for the large construction.

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.
