"In 2022, we decided to add a new kitchen and substantially remodel our mid-1960s Edmonds rambler. After reading many on-line reviews and meeting with several contractors we decided to go with Johnson and Sons.....and we are so very happy that we did. From the very start we were impressed with how open, honest and responsive Vic Johnson was, a trend that continued throughout our project. As you might imagine, a significant remodel and addition to a 60-year old home is likely to bring with it surprises and our remodel was no exception. Despite the many challenges encountered, Johnson and Son and their subcontractors readily overcame them. Among the many lessons we learned during our remodel was the value of quality subcontractors. Vic's relationship with his subs in some cases extend more than a decade and the depth of these relationships was reflected by the quality and timeliness of their work. All in all we feel that the workmanship, attention to detail and care shown by all involved in our remodel was superb. We highly recommend Johnson and Sons to anyone looking to remodel their home."

"Everyone at Renovate was excellent to work with, communicated well, and obviously cared about doing quality work according codes and rules. Our project had a couple surprises (asbestos!), and we ending up spending more than we thought, but the whole team made it a positive experience, and we would love to work with them again on the next phase of our basement!"

"Ryan and his team completed an extensive basement remodel in our 1924 home. The basement work included new framing/drywall, windows (including a large egress window), plumbing and electrical to support a main living space, new bathroom and new laundry room. We also updated our old forced-air HVAC and water heather to new mini-splits and a tankless water heater. This is our second major project with Ryan and we plan to work with him for many years to come. He's incredibly responsive and detail oriented and always plans phases of our projects to support our future plans. Ryan's expertise and quality of work is well worth the cost."

"I hired Topaz Remodeling to replace my front porch, including tearing out the damaged surface, installing a proper drain (the original builder’s oversight caused major leaks), and repairing the resulting damage to the floor, hardwood, and basement. The owner’s communication was excellent, keeping me informed about schedules and progress. They even finished ahead of the estimated timeline. Omar, the project lead, was phenomenal. His recommendations elevated the final result, and his attention to detail was unmatched. The tilework is flawless, with precise measurements ensuring a polished look. The team delivered exceptional quality, turning a stressful situation into a seamless process. My new porch is beautiful and fully functional. I highly recommend Topaz Remodeling and will gladly use them again for future projects."

Basement Remodel FAQs, answered by experts

Renovations that add functionality or more comfortable floor space generally add the most value when remodeling your home. Attic or basement finishing can add floor space without altering the home's structure, saving you renovation money while adding valuable space. Smaller improvements, such as installing smart-home components or replacing entry doors and windows, also experience high ROIs. 

You should plan on waiting at least a year and ideally two to three years after construction before finishing your basement. This will give the foundation time to settle in response to the weight of your home and the expansion of the surrounding soil. You can then repair your foundation and seal any cracks as needed before finishing it to reduce your risk of future leaks or other issues.

Walkout basements cost more than other kinds of basements, and can also increase your risk of leaks as well as a loss of insulation, leading to higher heating and cooling costs. Improperly installed walkout basements may lead to structural issues with your foundation, so ensure you’re working with a contractor who has extensive experience with this kind of basement.

It’s less expensive to finish your basement than it is to build an addition to your home. The average cost to refinish a basement is $32,000 (between $7 and $23 per square foot) while building an addition to your home costs $50,325 ($80 to $210 per square foot). Depending on the size of your basement and other factors, like moving plumbing and electrical, refinishing a basement is a more cost-effective option in most cases.

Framing a basement takes three to five days, on average, when completed by a professional, though it may take longer for a larger space. Keep in mind this doesn’t include the time to complete the design, obtain permits, and install the drywall on the framing. On average, fully finishing a basement takes an average of 45 days.
