"We waited 1 year from project completion before writing this review for the 'honeymoon' period to wear off... but it never did. We went into this project with our eyes wide open, having heard so many stories of other peoples remodel projects ending in less than stellar results. Our experience with Johnson and Sons, from planning and project quoting thru demo and remodel, more than met our expectations. We would not hesitate in using them again and/or recommending them to our friends and family for their projects."

"My wife and I have been on a 18 month journey with Renovate to plan a significant basement remodel which included replacement of the main beam of the house and a dig out of a crawlspace to expand the footprint of the basement. Along the way, Amanda and her team (especially Jeremiah and Ross) have been utterly professional and helped us craft an amazing vision for the project, with lots of changing scope and financial constraints on our side that changed along the way. It was always easy to get on the phone with someone there and to talk things out when we needed to discuss something or revise our plans and they were always great about working out multiple options to solve problems as we encountered them. What we wanted to do was really ambitious and they always had a steady hand at the wheel. We were especially grateful that, in order to save us money, they would allow us to contract with an excavation company directly in order to bring the project within budget. Ultimately, we had to shelve the project until financing it would be more feasible, but Amanda was extremely gracious and understanding even about that turn of events. And, in the end, we have engineering drawings and floorplans that we can keep until the time is right to do the work, so it wasn't all for naught."

"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."

"Ilya and team were great! Communication was timely and constant. Ilya is a hard hard worker and made our master bathroom amazing. He took out our tub and single shower and installed 2 shower head bathroom with heated flooring, floating vanity, and another light above the shower. He is respectful of our home and a dog person for sure! He left everything nice and neat and went through thoroughly to ensure he did not leave any dust or debris past his working hours. Would recommend to friends and family! Easy, much cheaper than our other quotes and he did it all within our agreed upon timeline! Please use GASHIN and support local!"

"I had an outstanding experience with Anyvision Home Remodeling on my master bathroom remodel. Chase and his team were incredibly professional, reliable, and communicative, demonstrating true craftsmanship and attention to detail. In addition to the master bath, they also rebuilt a guest bathroom shower that had been poorly done by a previous contractor, and the difference in quality was remarkable. Their dedication to excellence exceeded my expectations, and after a frustrating experience with another contractor, it was a relief to work with a team that is both highly skilled and trustworthy. I highly recommend Anyvision Home Remodeling for anyone looking for a stress-free, top-quality renovation."

FAQs for basement remodeling projects in Bothell, WA

Finishing a basement turns unused square footage into livable space and returns up to 70% of what you spend when you sell your home. Beyond that resale boost, you gain a playroom, home office, or guest suite you can start enjoying right away. That mix of daily comfort and solid return on investment (ROI) makes basement finishing one of the smartest upgrades you can tackle.

In some parts of the country—especially lots on swamps, high water tables, or other wetlands—local codes prohibit basements. Saturated soil puts constant pressure on foundation walls and lets water seep in faster than any sump pump can handle. 

If your property sits on waterlogged ground, building on a slab or crawl space is often safer, more affordable, and code-compliant.

Most basements wrap up in four to eight weeks. Framing takes three to five days, with electrical and plumbing rough-ins following over the next week. Add five days for drywall, two to three for flooring, and another week for paint, trim, and punch-list items. 

Delays can happen if materials run late or your contractor’s calendar is packed, so build in a little cushion when you plan.

Whether a finished basement counts toward your home’s official square footage depends on local rules. Many areas only include below-grade space if it has code-approved egress, fully finished walls, ceilings, and floors, plus consistent heating. 

Check with your local assessor or building department before you start; meeting those standards can affect taxes, appraisals, and resale value.

Building codes require a checklist: dedicated heat and electrical service, a code-approved stairway, and at least one egress window or exterior door. Walls, ceilings, and floors must be fully finished and meet insulation, ventilation, and fire-separation standards. If you add a bedroom, you’ll also need a closet, proper clearances, and safe exits. If you change the layout later, be ready to update the space so every new room still meets today’s code.
