"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."

"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!!"

"We recently worked with Johnson Custom Builders to complete a total remodel of our master bathroom and we are absolutely thrilled with the results. We interviewed about 5 companies for the job, and it was clear from the start that working with the owner at JCB was a perfect match for us. This was our first major renovation, and we were anxious about...basically everything! We worked directly with the owner, and he made sure that we knew exactly what to expect at every point of the process. He encouraged us to dream big and then figured out ways to value engineer a solution that was closer to our budget. He brought experts into the project and was very respectful of our home and our family while the project was in process. He was the perfect blend of consultant, designer, builder, project manager, and sometimes even a mediator (!) when we couldn't agree on things. We are excited to continue remodeling our home in the coming years and wouldn't dream of using anyone other than JCB."

"Good end result, but be ready to run the project yourself I hired Topaz Remodeling for a 50K basement finish. Some areas look good. But it required constant oversight. The serious stuff: The crew punctured a fully exposed water pipe 6 inches in front of them. Live wiring was left exposed above the ceiling with no junction box. I found it. That knocked out my greenhouse circuit, costing me about half my plants. Drywall went up before these issues were caught. Management: I was told a manager would be on site every other day. I saw one once. Communication went quiet after payments cleared. After a nearly two-hour milestone meeting, they requested payment early and disputed the terms. Quality: The shower door didn't fit because the base had a non-standard 2.5" threshold. The replacement failed after a week. Bottom line: The craftsmanship is there, but the homeowner has to catch the mistakes. If you hire Topaz, be prepared to manage closely and inspect everything before paying."

Basement Remodel FAQs, answered by experts

Unless you have extensive experience in construction work, remodeling a basement is best left to a professional. There are several tasks associated with this project that require exact precision, including:

  • Replacing insulation 

  • Replacing carpet or other flooring 

  • Adding heating and cooling

  • Adjusting or adding walls and doors

  • Altering or adding plumbing elements

If any of these elements is done incorrectly, it could severely impact the quality of your basement remodel and be dangerous. Changing a basement often comes with code safety requirements, like egress windows and proper ventilation. Therefore, leaving it up to a professional is often the best decision.

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.

For most basement remodels, you’ll want to hire a general contractor. This is for a number of reasons, but the main two are that general contractors have dedicated teams they are comfortable with, and hiring one means you only have to deal with one pro. You may also get a better project quote since they can lump all their work and subcontracting into a single quote. 

When choosing materials for finishing basement walls, consider factors such as moisture resistance, durability, and fire resistance. Opt for materials specifically designed for basement environments, like moisture-resistant drywall or cement board. Insulation with vapor barriers can help regulate temperature and prevent condensation. Consider using mold-resistant paints or coatings. 

Research and consult with experts to select materials that are suitable for your specific basement conditions and intended use. Prioritize quality and compatibility to achieve long-lasting and aesthetically pleasing results.

Installing a bathroom in a basement isn’t a project for most homeowners. Many parts—plumbing, electricity, and carpentry—go into this project, each requiring expert-level knowledge and tools. One miscalculation can lead to very expensive repairs. Plus, some homeowner’s insurance might not pay for damages caused by a homeowner DIYing this project. You can protect yourself by allowing the pros to complete this job for you.
