"You will love working with this contractor. Honest to a fault, generous beyond compare and a wonderful dry sense of humor. I chose Allset because he was willing to let me do part of the work in order to save costs. Others that I spoke with only wanted to do all the work. I highly recommend Scott for any project you might have."

"Leo and helper rebuilt outdoor stairs and did a very nice job. He was quick and professional from first contact to job completion. But, he underestimated wood needed for replacement of deck boards and he didn’t bid the cleanup/disposal of removed wood so the quote was short by $300. I would recommend Leo just be sure the quote includes everything you want done."

"Yes! Eduardo and his son did a great job and I highly recommend them to anyone. There’s a lot of contractors who reached out about this project but what I really liked and one of the reason why I hired them because when Eduardo came out to look at the projects he listened and and then he shared with me his thoughts, unlike the others who just insisted this and that and I even almost kicked one out of the house already. After all, we the homeowners are the customers . Anyways, there’s more projects ahead of us and I definitely don’t mind having them to come out for estimate. We showed photos to friends and families and they all loved it."

"We worked with Ali (sales manager) and Tony (project manager), who took the time to design a project that made sense for our property and our budget, made a number of suggestions and recommendations and were never pushy or tried to "sell" us on something. The crew really went above and beyond to provide top quality workmanship and overall we were in very good hands. Highly recommended!"

Basement Remodel FAQs, answered by experts

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.

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.

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.

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.

Rebar is an essential part of reinforcing a basement floor, as not having it can impact its structural integrity. It helps absorb the tension factors that contribute to cracks in your floor and strengthens its load-bearing capabilities by evenly distributing the weight. Not including rebar could lead to an unstable floor, so don’t skip it!
