"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"

Basement Remodel questions, answered by experts

Yes, barndominiums can have basements. Barndominiums are typically built over concrete slabs, so barndo basements are not very common. However, it is possible to include a basement in a barndominium blueprint as long as you’re building completely from scratch. Barndos can have the same types of basements as traditional homes, including full or walk-out basements.

Efficient appliance positioning, optimizing existing plumbing, and sourcing energy-efficient materials reduce financial impact and increase sustainability.

Yes, you can install a summer kitchen or kitchenette in your basement. They serve similar purposes as outdoor kitchens, keeping the main floor of the house cool and providing another space to cook and congregate. Basement kitchens are also a worthwhile alternative for homeowners without much space in the backyard. They come with a few logistical questions to sort out, though, like ventilation and waterproofing.

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.

You should plan on waiting at least a year and ideally two to three years after construction before finishing your basement. This will give the foundation time to settle in response to the weight of your home and the expansion of the surrounding soil. You can then repair your foundation and seal any cracks as needed before finishing it to reduce your risk of future leaks or other issues.
