"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."

"J J Construction owner Khoa Ha completely replaced my upper and lower decks with composite. He solved many problems we were facing with the decks and designed a system to deflect rain water away from the house. The upper deck was 48'x12' and the lower deck 14'x21', also replaced existing stairs, added bench seating. and lights. In addition he also repaired/reflashed metal roof on the lower back of the house and address foundation concerns. His team were great to work with, hard working, professional and courteous. We could not be happier with the results of this 4 week project. I highly recommend J J Construction for any project. We will be using him on future projects as well such as house painting, and some interior remodeling in the coming year."

"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 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"

"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

The best type of basement ventilation system depends on your budget, the moisture in your basement’s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.

Lifting a house and adding a basement is one way to add usable square footage. Lifting or jacking a house is a complex process, and it can be expensive, not to mention that you won’t be able to live in your house while it’s lifted, due to safety concerns. Lifting a house should only be done by experienced professionals.

Common mistakes when finishing basement walls include neglecting proper insulation, insufficient moisture management, and poor ventilation. Not addressing these issues can lead to mold growth, water damage, and discomfort. Additionally, inadequate planning, improper framing, and rushing the project can result in subpar outcomes. 

It's essential to follow best practices, seek professional guidance if needed, and prioritize thoroughness and attention to detail.

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.

When considering finishing your basement, take into account a few pros and cons:

Pros

  • Can increase the value of your home

  • Separate space from the rest of the house 

  • Customize and personalize the basement to suit your needs and style

  • Increase the amount of living space in your home

Cons

  • May not regain enough value to cover the cost of finishing

  • Lack of natural light if it’s below ground level

  • Moisture or flooding can cause costly damage

  • Installing plumbing and electrical can be messy and costly
