"I hired Bob for our basement remodeling project and thatâ s the best decision we took. He is such a perfectionist with his job, gives right suggestions on what needs to be done, not at all money minded, and mainly manages work to be on time. He returned back to work immediately after his surgery just to meet the deadline. We are more than happy with the outcome. I sincerely recommend Bob for any work he is capable of doing and worth the decision. In fact, I kept pinging him for more suggestions even after the job is done and he is very responsive. So thankful that we were able to find Bob through my friend and he is a highly recommended person for any remodeling job."

"I cannot say enough about these guys. Their prices were reasonable and about average compared to other companies. The owner, Dave was great to work with, he kept us updated on a daily basis, and was there every morning to look things over and help get the guys set up. The workers were there at 7 am every day. Work was done well within the given timeframe. Everything was left clean each day. They built a bedroom in our basement, and gutted and remodeled a bathroom, we couldn’t be happier with both projects. Very professional, highly recommend."

"Arthur gave us a fair and competitive estimate and was able to start work quickly thereafter. He and his team did an excellent job gutting and totally remodeling two bathrooms and a closet as well as redoing some of the wood flooring, moving vents, and moving hallways. Arthur himself was at the home everyday and did the important work himself. He also went the extra mile in helping us with small projects around the major project as they came up. He was extremely responsive in provided us with timely updates. When complications occurred (due to the house having not been renovated in 40 years) he was clear and helpful in keeping the project on schedule. He was extremely honest and I trusted him to be alone in my house for weeks on end with his team. I would/plan to work with Arthur again in the future for my home renovation projects."

"Jose and his team were the best team I have ever had work on a job in my house. Jose went WAY above and beyond to make sure we had our basement back in order in a timely fashion. He was willing to work after hours if needed to help get our finished basement back after we had suffered a sewage leak and had to wait until mitigation was complete. A 3-4 day job was complete in 2 days! And one of his workers, Carlos, from the second day stuck around to help me get the heavy and large items back into the basement. There was a previous review that said Jose was very emphatic to their needs and that is so true. That review actual was what made me give Jose a call. I wish there was a word better than highly recommend. Thank you Jose and your entire team!"

"Jeff did a great job on our complete basement bathroom remodel last December so we asked him to do a small job of installing a vanity. The job was done quickly and efficiently. The price was reasonable. Everything was cleaned up. I highly recommend Northgate Home Improvement and will gladly hire them in the future."

"I hired Long Island handyman construction group to remodel a 400sf basement and bathroom in Melville. They were priced in the middle compared to other bids. I picked them thanks to their out of the box advice which saved me thousands of dollars. There was one problem with the plumbing which cost an extra 1800 dollars. The owner settled with me 50/50 even though it was a pre-existing issue. The project was started early and completed early. All mess was cleaned up and the crew was very friendly and fully aware. Very reputable guys and very easy to deal with. Thanks Moises and Eddy."

Basement Remodel FAQs, answered by experts

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.

Some older homes have toilets in the basement to combat sewage backups. This type of toilet, also known as a Pittsburgh potty, acted as a safety valve over the incoming sewer line. If a line backed up, it would back up into the toilet because it was the lowest fixture in the home, keeping it out of sight and away from the finished areas of the house.

Basement toilets were also used by workers with messy jobs, like those who worked in coal mines or steel mills. This way, they could clean up and avoid tracking dirt through their home.

Renovation enhances functionality, increases home value, and can add new space for personal or family needs. It typically modernizes older unfinished basements for new uses.

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.

Costs are guided by renovation scope, materials chosen, project duration, structural needs, and labor. Prioritizing tasks prevents unforeseen expenses.
