"Vic Johnson and his crew were extremely knowledgeable about construction in general, friendly and accommodating throughout the entire process answering a multitude of questions, pivoting when needed, helping educate us homeowners of the hows and whys, and bending over backwards to make things right...when work wasn't going to plan (and remodels never go perfectly as planned). They were fair, and provided an enormous value. I'd highly recommend Johnson and Sons for any remodel you may have."

"JJ construction was my #1 choice for remodeling. I made my appointment with JJ construction. The person showed up on time and very thorough. We were very pleased by their expertise and their advice. However, I decided to sell the house as is. No work was done on my house. But I do recommend this company for future projects."

"Renovate Construction was excellent at every phase of our Magnolia porch remodel! From the beginning of the planning visits, to the start and completion of the project, Renovate was a true partner! I appreciated they kept us in the loop on potential issues, challenges and scheduling. We received expert advice from an incredible team to ensure our project stayed on track and within budget! Huge thanks to Dave, Amanda, Mike and Ryan for an amazing job- we are so pleased with the results and now have curb appeal again! I will definitely refer/ work with Renovate again. Thanks guys!!"

"I couldn't be happier with how our basement remodel turned out Gold Remodeling made the whole process a lot easier than I expected everyone was professional without feeling overly formal and they actually listened to what we wanted instead of pushing their own ideas the finished basement looks amazing and has completely changed how we use our home here in Kirkland"

"Ryan and his team did a great job on our basement remodel. Communication was strong as was attention to detail. A concerted effort was made to keep the worksite clean. Like many renovations, it took longer than anticipated and we encountered a measurement hiccup that, while solved, could have been identified and addressed upfront"

Basement Remodel questions, answered by experts

Any bowing in a basement wall indicates a problem that needs to be addressed by a professional. If your basement wall bows more than 1 inch, it's time for an inspection. Generally, a wall can bow up to 30% of its thickness (around 2.5 inches for an 8-inch-thick wall) before it becomes an urgent situation. Bowing of 2 to 4 inches is more straightforward to fix than bowing of more than 4 inches, which will require significant repairs. If the bowing is more than 6 inches, the wall will likely need to be replaced. The sooner you address the problem, the easier and less expensive the repair will be.

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.

Anything having to do with the structure of your home, such as raising the ceiling, is usually the most expensive part of finishing a basement. Another project component that could be a surprisingly high expense is adding an exterior entrance. 

The cost of a walkout basement can be anywhere from $5,000 to $35,000.

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.

It is generally more affordable to finish a basement than an attic, though it ultimately depends on how you plan to use the space. The average cost to finish a basement ranges from $7 to $23 per square foot, while attic renovation costs $30 to $60 per square foot. However, a simple attic conversion to a storage space will cost significantly less.
