"Nick Cleveland was very helpful in evaluating our needs for the project. He came up with a good and economical solution for repairing deck railing for which replacement parts are no longer available. He showed up on the job when he said he would be there and finish the work in a very timely manner. Rich from Tyrone, NY"

"Modern construction was efficient, professional. Performed as we talk about what was needed. I would hire them again if needed. They kept us informed with all the steps they performed. I would give them 100% if I could."

"So happy we chose R&D for our exterior wall repairs! they were great to work with throughout the process of what turned out to be a complicated issue. Their communication was really appreciated as they dug into things and problem solved some unique issues with how the previous home owners had cut corners on the house. R&D wasn’t the cheapest initial bid we received but I have no doubt that we would have wound up paying more in the end for a lower quality result with anyone else. Thanks guys!"

"Although a slight problem at the beginning with both ends finding a mutually agreeable time to meet to discuss the project, I felt a good job was done by TriCounty Remodelers. Initial options were asked about and a secondary solution was agreed upon after some more local research was completed. A slight push back was experienced, but that was due to uncooperative weatherfor the initial start of the project. Better options were also offered and accepted in the doing of the project. The project was fully completed in the time alloted. All demolished materials were removed after work was completed each day. I will be having more work performed by these professionals during the next constructuion season in 2010."

Basement Remodel FAQs, answered by experts

Installing a bathroom in a basement isn’t a project for most homeowners. Many parts—plumbing, electricity, and carpentry—go into this project, each requiring expert-level knowledge and tools. One miscalculation can lead to very expensive repairs. Plus, some homeowner’s insurance might not pay for damages caused by a homeowner DIYing this project. You can protect yourself by allowing the pros to complete this job for you. 

Common mistakes when finishing basement walls include neglecting proper insulation, insufficient moisture management, and poor ventilation. Not addressing these issues can lead to mold growth, water damage, and discomfort. Additionally, inadequate planning, improper framing, and rushing the project can result in subpar outcomes. 

It's essential to follow best practices, seek professional guidance if needed, and prioritize thoroughness and attention to detail.

Walkout basements are not generally included in a home’s square footage, although they may be if they meet certain conditions that depend on local regulations. A finished walkout basement used as a living space may be counted toward square footage in some locations as long as all codes for livable space are met.

A finished basement must have a heat and electrical supply with an entrance that meets building code requirements, such as a stairwell to the home's main living space. It often must include finished walls, ceilings, and floors. If the finished basement includes a bedroom, it should have a heat source, an egress window, and a closet.

Remodeling, as opposed to finishing, means altering an already finished basement by adding a bathroom, bedroom, or living area.

There are several small, inexpensive upgrades you can make to upgrade your basement. Although you still need to adhere to building codes and obtain permits when necessary, you can complete small but mighty tasks like painting the masonry walls and installing entertainment devices to make the space more usable.
