"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."

"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."

"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!"

"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."

Basement Remodel questions, answered by experts

It is common for a contractor to ask for a down payment before starting a project, especially for jobs that require purchasing materials and equipment or hiring a crew. The deposit amount can range from 10% to 50% of the total job cost. While a request for up to 50% is not unusual, a contractor should not ask for more than that, and you should never pay for a project in full before the work has begun. To protect yourself, always discuss payment terms before starting and have a written contract that outlines the project timeline and expectations. Additionally, be sure to hire reputable contractors and check their licensing and insurance before the project begins.

If you don’t have a crawl space but have a partial basement you want to make deeper, you can expect to spend a little less—between $40,000 and $90,000 on average. However, if you’re not adding new finished square footage, you won’t see much in the way of ROI.

To determine if your basement walls are suitable for finishing, assess their structural integrity and moisture conditions. Look for any signs of damage, such as cracks, bowing, or excessive moisture. Ensure proper drainage and address any underlying issues before proceeding. 

Consult with a professional if you're uncertain about the structural stability or potential risks associated with finishing your basement walls.

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. 

Yes. Renovating your basement has a return on investment (ROI) of 75%, meaning your remodel investment will significantly increase the value of your home. Besides the ROI, your family can enjoy a larger, more usable space while you live there.
