"My husband and I are in our 70’s. All of the upgrades/construction in our house in over 26 years was done by my career-construction husband. But recently he hurt his back. We needed our guest bath prefab bathtub/shower removed and replaced with a NICE prefab WALK-IN shower handicapped out. Our 95-year old mom was coming for a 2-week visit. We only had 3 weeks notice. Ani Kevorkian, owner of LGC Construction came to our house 1 day after I called. She listened, REALLY listened to what we wanted and understood the time constraint. She gave us a quote within hours and started the job within days. Her two gentlemen who came out were just awesome and cleaned everything up each day. Then Ani surprised us with “barn-door” glass shower doors that we didn’t even know we were getting. The shower is just beautiful! This company is exceptional. I have and will continue to tell our neighbors, people at our church, friends, etc. about LGC Construction! You can TRUST THEM!!!!"

"We did a 3 room kitchen and bath remodel in just under 3 months, and we are over the moon with how well everything came out! Micky and his team are simply superb — every team he brought in did top notch work, including tiles, flooring, plumbing, electrical, countertop, cabinets, glass, stucco, windows, drywall, and more. Micky coordinated everything to perfection, ensuring the project was progressing day to day, sometimes hour by hour. The only “negative” was that we had to work hard to keep up with their impressive pace (in terms of making decisions and ordering needed supplies) and it was well worth it! We are now starting an ADU conversion and we can’t wait for the results."

Basement Remodel questions, 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.

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.

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.

While framing a basement is not as difficult as finishing a basement, it's something you should typically leave to the pros. That’s because if something is installed correctly, it will affect your entire basement. However, you can take care of some of the smaller tasks, like filling holes or putting up some insulation.

A finished basement does not always count as square footage, though this varies by state regulations. You may live in an area that allows for below-grade spaces to be considered in a home's official square footage. In those cases, the basement must meet certain conditions, like having a functional egress and being a livable space with flooring, finished walls, and temperature control. Your local assessor can confirm your area's policies regarding basement square footage.
