"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.

"Carlos has been helping us with some framing items we needed to take care of in the midst of a renovation of our 1926 home.

"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."

"We worked with Renovate from August 2024 through April 2025. Our experience was exceptional. Ross, Eric, and Jeremiah were efficient and effective, treating our project with great care. The Renovate team stands out in several ways: - Their pricing is transparent. We paid an hourly cost and subcontractor costs, plus a fixed mark-up, which aligned incentives. Amanda provided receipts and timesheets regularly. - They have superb attention to detail. They pointed out issues we might have missed and ensured they were fixed. - They were super responsive, encouraging us to text or email any time and often responding quickly. They kept us updated on the timeline and explained any delays. - They have a strong client focus.

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. "

FAQs for basement remodeling projects in Federal Way, 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.
