"Just moved to Astoria and realized the backyard wall was not going to safely secure our dogs. He had a crew at my house the following week. Tyler also provided an alternate idea to my thought about how it should be done, and his idea was much better. The end product is perfect. Tyler would stop by and check on things every day. He kept me informed at every step by calls or text messages. Highly recommend this company!"

"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!

"We actually had Bellos Construction do considerably more than just a bathroom remodel. Additional work included installing flooring, installing insulation and drywall, demolition work, roofing repair, etc. Overall the experience was good. Jose is very responsive and helped me out quite a bit dealing with renovating and repairing an older house that was not properly taken care of by the previous owners/renters. The only real issue we had was confirming the materials that would be installed in the bathroom (i.e., fixtures, etc). There was some miscommunication there that probably was not helped by the fact we are out of state and trying to manage a construction project. One thing that stood out about Jose was his willingness to help out with things that didn't fall under his contractual obligations. For example, he helped me transport a water tank when he didn't need to do so. If we have a need for services that Bellos Construction offers, then we will definitely consider them in the future given our experiences with them."

Basement Remodel FAQs, answered by experts

Installing a bathroom in a basement isn’t a project for most homeowners. Many parts—plumbing, electricity, and carpentry—go into this project, each requiring expert-level knowledge and tools. One miscalculation can lead to very expensive repairs. Plus, some homeowner’s insurance might not pay for damages caused by a homeowner DIYing this project. You can protect yourself by allowing the pros to complete this job for you. 

A finished basement must have a heat and electrical supply with an entrance that meets building code requirements, such as a stairwell to the home's main living space. It often must include finished walls, ceilings, and floors. If the finished basement includes a bedroom, it should have a heat source, an egress window, and a closet.

Remodeling, as opposed to finishing, means altering an already finished basement by adding a bathroom, bedroom, or living area.

Yes, you can add a bathroom to an unfinished basement, but you’ll want to take proper precautions if doing so. As with any bathroom addition, you’ll need to make sure that it’s approved by local building authorities first. With unfinished basements, you especially need to keep an eye on proper ventilation practices.

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.

A walkout basement is considered to be partially below grade because at least one wall is entirely exposed. In some cases and in specific municipalities, inspectors and appraisers will still count walkout basements as below grade, which means the space can’t serve as living space or be rented out. If you intend on using the area as living space or a separate apartment, you should check with your local building department to make sure it’s legal to do so.
