We have the experience and we are committed to providing quality workmanship and superior customer service on all our applications. We at Christiansen Carpentry strive to maintain our reputation as a high quality, very service oriented company with our main focus being customer satisfaction.

"Unprofessional, untimely, poor workmanship, stressful experience. Shawn did a LVP flooring install on two levels of my house, including the kitchen. Almost $8K for 1K SF. Flooring failed 1st time due to no subfloor leveling despite me asking twice if it was needed. 24 planks in 600 SF were separating in 2 weeks. Once I informed Shawn the floor was failing, his workers tried accessing my garage without permission to get tools. Seemed like they were trying to split on a bad job. Despite the bad job done, I worked with him on cost-effective products to try and save as much money as possible on the rework. Both levels of flooring had issues, but I only asked for main level to be redone. Ultimately, it took 4 months of poor communication and terrible customer service to finally get new flooring installed, still not level but holding????! Ultimately, the new flooring installed was left unfinished, leaving me to install trim, transitions, end caps, stair nosing and caulk on my own."

Basement Remodel questions, answered by experts

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.

Create a checklist, reimagine the space use, set a realistic budget, choose materials and aesthetic details, and get professional support for guidelines and troubleshooting.

Adding a bathroom to your basement can increase your home value since homes with multiple bathrooms sell for more. The return on investment (ROI) for a basement bathroom is 50% to 75%. The actual return varies with your home and location. Adding a half bath to your home increases the value by 2.9% while finishing a basement increases the home value by 6.6%.

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.

While framing a basement is not as difficult as finishing a basement, it's something you should typically leave to the pros. That’s because if something is installed correctly, it will affect your entire basement. However, you can take care of some of the smaller tasks, like filling holes or putting up some insulation.
