"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

Although it’s not required, air ventilation in a finished basement can help improve the air quality, prevent moisture and mold issues, keep musty odors away, and also maintain the air quality throughout the rest of your home. Proper ventilation will help maintain the value of your investment in finishing your basement. Try basement ventilation methods like installing vents or a dehumidifier for best results.

Physically, the most challenging part of finishing a basement is installing egress windows or doors when the space is below ground level. Mentally, the hardest part may be envisioning the project and planning around load-bearing and mechanical obstacles.

The average cost to remodel a basement is between $12,100 and $33,400. Depending on the project's complexity, the price can be as low as $3,500 or exceed $50,200. For a simple project like adding a home office, you might spend between $500 and $3,000. However, a more extensive project, such as adding a bathroom, can range from $6,600 to $16,500. The final cost is influenced by factors like the basement's size and condition, the type of remodel, material choices, your location, and accessibility. For an accurate price, it's best to consult with a basement remodeling team.

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.

Yes, most general contractors require an initial down payment. A reasonable deposit is typically between 10% and 25% of the total project cost, although this can vary by project size and location. This upfront payment helps the contractor cover initial costs like materials, permits, licensing, and hiring subcontractors. The remaining balance is usually billed according to a schedule outlined in your contract, often tied to project milestones or completion dates. Be cautious of contractors who ask for a large deposit of 50% or more, as this could be a red flag for a scam.
