Carpenters cut, measure and shape lumber in useful ways. Working from a master plan, they create wooden structures, piece by piece. Their work involves mastering a wide variety of hand and power tools. Some of the work they do involves cutting wood using chisels, planes, saws and sanders.

"The first picture is our family deck before and the second is after. I could not recommend Norsemen Construction enough! The founder is extremely reliable and reasonable, they are willing to make sure you get what you are looking for and then some. They had also done two door replacements for us, beautiful work. We will be contacting Norsemen in the future!"

Basement Remodel questions, answered by experts

Yes, finishing a basement is worth the money in most cases. Although the project is a relatively expensive one, finishing a basement adds usable square footage to your home and typically increases your home value. Many times, your finished basement will add value that’s equal to or greater than the cost of finishing.

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.

The average cost of remodeling a basement is $30 to $75 per square foot. If your space is unfinished and looks like it may need more help, use the higher number when calculating your estimated basement remodeling costs. A good rule of thumb is to add an additional 20% to the top of your estimate to cover any “what if” situations.

Yes, you can add a bathroom to an unfinished basement, but you’ll want to take proper precautions if doing so. As with any bathroom addition, you’ll need to make sure that it’s approved by local building authorities first. With unfinished basements, you especially need to keep an eye on proper ventilation practices.

Finishing your basement adds value to your home, providing an average return on investment (ROI) of around 75%. That means the typical basement refinishing costs of $32,000 will add an average of $24,000 to the value of your property. The value added to your home will depend on the price you pay to have the work completed, the area you live in, the quality of the work and building materials, and more.
