"I recommend Martin Hartel without hesitation. He and his crew are the best contractors I have ever dealt with. I am so happy and fortunate to have been able to use their services to complete our dream basement. First of all, Martin has so much experience, expertise and skill. His craftsmanship is impeccable. And his ability to work with you to pull out your ideas, and turn them into reality, is awesome. He is extremely patient and smart, and knows how to balance cost and quality to deliver what you want at a fair price. Some of the things that most impressed me were his attention to detail, desire to do quality work, and just their overall goal to make sure the client is happy. I could tell he was treating my job as if he was finishing his own basement. The framing and wiring were impeccable. Many contractors will do sloppy work with wiring, figuring it will be covered anyway. Martin’s wiring was so clean, smartly run, and used the best materials. The subcontractors he works with are also top notch. The drywall and painting were done quickly and to a high standard. Finally, the overall design and fit and finish were excellent. Everyone who sees our basement is blow away. From the wet bar, to the bathroom, to the custom iron railing, everything is perfect. And I can tell you that his price was substantially better than what the builder wanted to basically do four walls and lighting. Honestly I’m so pleased I wish he could remodel my whole house! If your considering a basement remodel project, do yourself a favor and try to get on Martin’s schedule. You won’t regret it!"

"Jon and his crew were amazing to work with from start to finish! They listened to what I wanted and made my dreams come true. My parents were having a hard time on their own so I finished their basement into a little house for me and my family to be close to them to help and it turned out exactly like I wanted thanks to Jon and his crew. Donâ t hesitate, hire him today! You wonâ t be disappointed."

"Their manager came to the house and he was very helpful and had some ideas on our kitchen remodel. Before he left he said he would have a quote by next week. I got a call from him that following week and said that our kitchen remodel estimate was running in the mid 40â s and thatâ s not touching the pantry. He asked would you like for us to proceed. I said absolutely and I have heard nothing back from them. So my decision to go with another contractor was an easy decision"

"We consulted with Robert Horne Contracting to remodel a very dated bathroom for us. From the start, they were very communicative from when he'd have the estimate (we ended up getting that earlier than anticipated) to picking out fixtures to start date. As with any old house, there were some challenges with hidden things which added to the tasks needing to be performed. He told us about those as they came up and gave us the very reasonable estimates, if the issue required extra work. He was able to remove the build-out above the sink and rework the plumbing to vastly open up that space giving the appearance of a bigger, roomier room. We did a walk-through and got written confirmation of our punch list items. He gave us a date of when he'd be out to complete the odds and ends and was there promptly on the given day. We are very satisfied with the work he performed and especially with the communication. We never once wondered when he'd be there or what was going on with products being delivered, etc. We are very happy customers!"

"Philip helped us change a cabinet board under the sink which was damaged by a water leak. He has a lot of knowledge and experience. The price is reasonable. We plan to hire him for our house maintenance and remodeling job in the future."

Basement Remodel questions, answered by experts

Renovations that add functionality or more comfortable floor space generally add the most value when remodeling your home. Attic or basement finishing can add floor space without altering the home's structure, saving you renovation money while adding valuable space. Smaller improvements, such as installing smart-home components or replacing entry doors and windows, also experience high ROIs. 

Roughing in and connecting utilities are the hardest parts of finishing a basement, and they’re the parts we typically don’t recommend doing as a DIY project. Unfortunately, your finishing timeline can be extended by weeks while you wait for contractors and inspectors to install electrical wiring, plumbing lines, and heating/cooling equipment and carry out inspections.

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.

Walkout basements cost more than other kinds of basements, and can also increase your risk of leaks as well as a loss of insulation, leading to higher heating and cooling costs. Improperly installed walkout basements may lead to structural issues with your foundation, so ensure you’re working with a contractor who has extensive experience with this kind of basement.

Making a window in a basement larger costs an average of $4,200. You’ll need to pay an average of $550 to have a structural engineer plan the project, $500 to $1,500 for the installation labor, and an average of $2,200 for the excavation and window well installation. The remainder will go toward pulling permits, installing trim, and repairing drywall on the interior.
