"Oscar and his team were great. They gave an estimate less than a day after I requested a quote and came to do the work within a week. They were on time, professional, and did great work.

"Gil did an amazing job of figuring out exactly what I needed, and he hired an amazing crew to get it done. This is by far the best home renovation experience I've ever had. Gil and Oliver both were very thorough in figuring out what needed to be done, and every step of the way if there was ever any ambiguity, they asked questions and came up with great solutions for everything that came up. I have never before had such a good experience with a home renovation, and I wish all contractors were as good as them. My project was fairly involved, with a complete renovation of my kitchen, dining room, and laundry room, and yet the whole process took under a month to get done, and it was done right the first time. I wholeheartedly recommend Your Home Builders. No complaints at all."

As of April 2025, my wife and I decided to take the next step and become a licensed, bonded, and insured general contractor as I transition out of the military via retirement. Prior to that, my wife and I have over 12 years of experience together doing fix and flips, fix and holds, working on our own properties, completing projects for family and friends, along with taking on side jobs. We are fully capable of any remodel, aided by our 4 employees and growing, plus our solid sub-contractors that we have used over the years after going through a few unreliable ones, so you don't have to! When working with Apex Home Solutions, you can count on consistent and clear communication, being a part of any decision point that arises, and have the peace of mind that timelines and budgets are managed responsibly. All of our employees go through an extensive background check. Reach out for your free estimate, you won't be disappointed with our finishes.

"We were among Apex’s first clients and had them totally remodel two bathrooms and partially remodel a third. We appreciated not only their “can-do” attitude but also their skills to back up the attitude. We also appreciated that they didn’t try to upsell us; Zach always had high-end options for us to consider, not to increase the costs but only because he wanted us to be happy with the results, and if we wanted to keep things simple/inexpensive, he was happy to accommodate us. We are super happy with our new bathrooms and will definitely call on Apex for our next projects. "

Current Super Service Award Winner for 2019 seven years running! Johnson Custom Builders is a Design Builder. Our approach is simple. It all starts with listening. We work closely with our clients to understand everything from their needs to their design preferences. Then we go to work helping them exceed their goals. www.johnsoncustombuilders.com Our process is completely transparent. Our estimates are designed to provide realistic expectations not best-case scenarios. For us, communication is key and we keep you completely informed every step of the way communicating in a way that helps you anticipate and act to effectively engineer the best possible solutions every step of the way. At Johnson Custom Builders our approach is never just about managing timelines and budgets its about delivering on promises and helping you realize dreams. One look at a Johnson Custom build and you'll immediately understand why so many discriminating customers recommend us to their friends looking for a higher level of customized home building. It's not just about the attention to detail or use of the highest-quality materials or even the custom-crafted details. It's about the personalization. Personalization that comes from a builder that not only knows how to listen but also how to anticipate, communicate and most of all deliver on a promise. A native of Kirkland, Washington, founder Ryan Johnson shares the same core values as the community he has always called home: Integrity, Honesty and Originality. He's been actively designing, building and remodeling homes in the area for over 25 years. And in that time, he has earned a stellar reputation for providing outstanding results crafted with uncompromising integrity and quality. Hes also earned a reputation for delivering on his promises. A+ rating on the Better Business Bureau (BBB) !

"Since I now need to use a wheelchair, several doorways in my home needed to be widened. Two exterior doors had to be replaced, one of which also had to be changed to open out rather than opening in. I hired Johnson Custom Builders and was absolutely delighted with their work. They were always professional. They laid or hung plastic sheeting to contain the dust they created, then at the end of the day they ran the vacuum and even mopped the floor! They were respectful of me and my home. Their work was excellent. One of the things I most appreciated was Ryan Johnson's communication with me before, during, and at the conclusion of the project. He listened to what I needed and then figured out how to make it happen. I recommend Johnson Custom Builders highly!"

We are a family owned & locally operated general construction / remodel company with over 60 combined years in the industry. Although we are general contractors and can do everything, we specialize in kitchen and bathroom remodeling. We have found that through proper communication and great listening our customers are more at ease and comfortable from beginning to end. It is our pleasure to provide top service in design assistance, material decisions, planning, demo and project completion. We go out of our way to uniquely tailor our service to each of our customers needs, wants and desires. We realize our customers invite us into their homes to provide the best service possible and we don't stop until we have done our best to help our customers turn their dreams into a reality. Thank you kindly for taking the time to look into Johnson and Sons Construction, LLC. We look forward to the opportunity to serve!

"I reached out to Johnson & Sons and several other contractors to discuss the possibility of opening up and completely remodeling my kitchen and bathrooms, with the addition of a shower to the former half bath off the master suite. After receiving bids and meeting with each contractor, I went with Johnson & Sons due to the transparency and consideration Vic Johnson showed when discussing the project and its challenges, as well as providing a detailed quote. Because this remodel involved the removal of walls, tiling of the kitchen/bathrooms, potential size constraints, and a re-plumbing of the house, It was very important for me that things be done correctly, to code and with permits. Once demo and construction started, things proceeded at a brisk pace with minimal lag between subcontractors, and inspections. Their tile guy, Tony was great to work with and very helpful with making the appropriate detail selections around the showers. We did have a long wait for a cosmetic piece of cabinet siding, which ended up being the final part needed to complete the project. Vic was direct with me about the issue and the delay. Such a minor issue is in my opinion, very small potatoes compared to having quality work done. Ultimately, Johnson & Sons came in slightly under their contract price - a very pleasant and welcome surprise."

FAQs for basement remodeling projects in Seattle, 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.
