"My wife and I were looking for a contractor to remodel our master bathroom. We were looking for someone that was knowledgeable, honest, fair in pricing, and great with communication. Victor from VAP Contracting was exactly that. Victor told us exactly when he would start, what he would need, and always answered any questions that we had. His team arrived every morning on time and was very polite. They were very neat and cleaned up each day and truly did an amazing job! Our new bathroom looks great. Victor stands behind his work and we look forward to working with them again on other projects that we have."

"We had a fantastic experience working with Dave and his team at Westbrook. Dave is highly professional, honest, friendly, thorough and a great communicator. And so are his team of workers. We worked with Dave to finish our basement and they exceeded our expectations every step of the way. He provided valuable input throughout the entirety of the planning process. And the uncontrollable issues we did face, he was there to help troubleshoot and ensure our 100% satisfaction."

"We live in Bronxville, where the expectation are high for quality of work done on houses. Bud, and team, did an amazing job with a pretty large job. It was a full basement remodel, down to the studs, and he was great to work with. Really appreciate his professionalism and quality. I would recommend him fully, even for jobs that are larger and require a high level of finish quality."

"Angela gave me a fair estimate for my bathroom remodel, not over inflated like most contractors. The workers were courteous, professional, knowledgeable, detail oriented, and kept the work area super clean the entire week they worked on my bathroom. I am very happy and satisfied with the final product. I would absolutely contract Hire Her Home Improvement again!"

"We hired Gustavo to remodel a 1960s house we purchased and we are pleased with the outcome he and his team delivered. Remodeling included vaulting our living room and kitchen ceilings, adding steel beams and refinishing kitchen and bathrooms with new plumbing, cabinets and tiles. Gustavo is very knowledgeable in all aspects of construction and the codes. His team and the subcontractors listen to him and they work together very well. Overall, we were very pleased with his work and we would hire him for future projects again."

"Guardian took care of our basement renovation in Somers, and I couldn’t be happier with how everything turned out! They added an additional bathroom, which required a new sump pump and sewage ejector pit, redid all the electrical, and even connected us with a reliable architect. They were also a huge help when it came to picking out finishes and making decisions throughout the project. I had a million questions, and they were always patient, took the time to explain everything, and never once made me feel dumb for asking (even though I probably asked way too many!). What I really loved is that they’re a true family business. I got to meet all five brothers and their father, and every single one of them was a pleasure to deal with. You can tell they genuinely care about their work and their customers. Couldn’t be happier with Guardian and our new basement. Great people, great work, and a company I would recommend to anyone!"

"Every step of the way was above expectations. Scheduling was easy, I was notified of ETA, and Al, our technician, was prompt and thorough. We needed our gas fireplace cleaned, and the job was done thoroughly, carefully, and efficiently. Our 25+ year old fireplace now functions perfectly and looks amazing. Can’t beat the price. 10/10 recommend."

Basement Remodel FAQs, answered by experts

Anything having to do with the structure of your home, such as raising the ceiling, is usually the most expensive part of finishing a basement. Another project component that could be a surprisingly high expense is adding an exterior entrance. 

The cost of a walkout basement can be anywhere from $5,000 to $35,000.

If you don’t have a crawl space but have a partial basement you want to make deeper, you can expect to spend a little less—between $40,000 and $90,000 on average. However, if you’re not adding new finished square footage, you won’t see much in the way of ROI.

Yes, most general contractors require an initial down payment, typically between 10% and 25% of the total project cost. This upfront payment helps cover the costs of materials, permits, and subcontractors. The remaining project costs are usually billed after specific project milestones are reached or on set completion dates, as outlined in your contract. Be wary of contractors who require a significant deposit of 50% or more upfront, as this could be a red flag for a scam.

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 difficulty of adding a basement to an existing house can vary depending on the house’s location, the size of the basement, and the type and condition of the existing foundation. Adding a basement is a job best handled by the pros, so you’ll need to enlist professional help for this project.
