"Adam and his crew did amazing work going above and beyond expectations. Went out of his way to pickup things that were missing out of the shed kit. It was very appreciated that he picked up a vapor barrier so the shed would be built to last. Great communication and even better price. Wouldn't hesitate to recommend to a friend and/or use on future projects. Thanks Adam!"

I recently left the union as a journeyman carpenter and superintendent. I built custom homes in my 20’s after graduating from college with a bachelor’s degree in business administration. Before college I worked in all phases of construction from concrete and framing to finish work. I have a well rounded understanding of building and am passionate about what I do and the quality of work I provide. In my personal life I am led by Jesus. I enjoy running several times a week and working out in my home gym. My goals are to provide value to my clients and give back to my community.

"Beautiful work done by people who care. I had an old deck torn out and a new one built. The work is impeccable. Rob was accommodating as far as changes and special requests. His crew was on time and very easy to work with. Good communication and close attention to detail. I love my new deck. I will certainly hire them again."

"This was a real estate transaction that had urgent deadlines for repairs. Jordan was at the home to evaluate that same day I called him. They were able to come to the home within a couple days to complete the repairs so we could pass the inspection. They did an extremely thorough job, more than what was expected, and everyone involved was happy with their services. I would definitely use them again, and highly recommend this company to anyone needing repairs or remodeled work done!!"

"We had a custom made shelf that needed to be installed out our Corporate Office tower. Josh came in, was very professional, and did the installation under 30 minutes. The wall was perfectly flush underneath our large conference room T.V. screen. Very satisfied and would absolutely hire him again 10/10."

Basement Remodel FAQs, answered by experts

Basements with persistent moisture problems or flooding shouldn’t be finished until the moisture issues have been fixed. In addition, if your foundation is cracked, you have unmitigated radon levels, or you have asbestos or lead pipes, remediate the underlying problem before finishing your basement. Turning a basement into living space before fixing these issues can lead to serious health risks or structural damage. 

The most challenging part of finishing a basement is addressing moisture control. Basement waterproofing is an essential task that requires a professional’s skills and knowledge. If you don’t properly waterproof your finished basement, it’ll be vulnerable to dampness, water damage, and mold growth. Ensuring proper insulation and ventilation to combat these issues while meeting building codes adds complexity to your remodeling project.

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.

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 always use high-quality lumber for your framing in order to ensure it will last the test of time and resist moisture. Use 2-foot by 4-foot lumber that is pressure-treated for your framing.
