"I am thrilled to share my overwhelmingly positive experience with this exceptional contractor. Their team recently completed work in my home, transforming the kitchen and installing a bathroom along with an expert job in painting. The quality of their work is simply outstanding, with meticulous attention paid to every detail. The workers were a pleasure to interact with - neat, polite, and extremely professional. They always took the time to answer my questions and explain the process, which made me feel involved and at ease throughout the project. Their respect for my home and dedication to keeping the work area clean and organized was truly appreciated. As for Robert, the owner, working with him was a breeze. His commitment to customer satisfaction was apparent from our first conversation. He ensured everything was running smoothly, maintaining open communication and offering helpful advice when needed. Our first interaction with Kaitlin, the assistant, was just as impressive. She consistently answered calls promptly and courteously. Her responsiveness and professional demeanor made every interaction a pleasure. I wholeheartedly recommend this contractor to anyone in need of home improvement services. Their commitment to quality work and outstanding customer service is truly unmatched. You can expect your project to be handled with the utmost competence and care."

Basement Remodel questions, answered by experts

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, you can add a kitchenette to a basement. However, you’ll have to consider the costs associated with basement kitchenettes. If you’re starting from scratch in an unfinished basement, you’ll need to account for brand-new plumbing, electrical, flooring, and more in addition to the cost of the kitchenette. If you’re putting a kitchenette in an already finished basement equipped with plumbing and electrical, you’ll save considerable money.

Yes, finishing a basement is worth the money in most cases. Although the project is a relatively expensive one, finishing a basement adds usable square footage to your home and typically increases your home value. Many times, your finished basement will add value that’s equal to or greater than the cost of finishing.

For most basement remodels, you’ll want to hire a general contractor. This is for a number of reasons, but the main two are that general contractors have dedicated teams they are comfortable with, and hiring one means you only have to deal with one pro. You may also get a better project quote since they can lump all their work and subcontracting into a single quote. 

The cost to remodel a basement is between $12,100 and $33,400 for the average homeowner. The price you pay can be as little as $3,500 or as much as $50,200, depending on the size and condition of your basement and the type of remodel you're doing. 

If you're doing a simple project like adding a home office to your basement, you can expect to pay anywhere from $500 to $3,000. However, if you're adding a bathroom, which is an extensive project, you can expect to pay between $6,600 to $16,500.
