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

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.

You can paint your ceiling or install a drywall ceiling if the ceiling is unfinished, as they take up less headroom than drop ceilings. 

If there are pipes in the way of ceiling installation, you can do one of two things: reroute the pipes or adjust the installation to fit, which will cost extra.

Adding an extension or addition to your home costs more than a loft conversion in all but the rarest cases where the home's structural integrity is lacking. Because a home addition requires a new foundation section or significant structural upgrades to handle a cantilevered portion, the cost compared to almost any loft conversion is significantly greater for the same square footage.

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.

Yes, adding a walkout basement will usually bump up your property value. Most homeowners prefer walk out basements because the exposed wall that’s level with the ground provides more utility via a ground-level exterior entrance, and they can fit full windows, which adds natural light and ventilation to the basement area. The only exception might be in areas prone to tornadoes, as walkout basements aren’t as safe as regular basements during a tornado, particularly if they include large windows or glass sliding doors.
