"We were looking for someone to remodel our kitchen in Kent and honestly didn’t know where to start. A friend from work mentioned Fusion Builders and said to ask for Daniel. I gave him a call and he came by the next day to take a look. From the first meeting, Daniel was super professional and easy to talk to—he gave us ideas we hadn’t even considered, like opening up the wall to the dining area for more light. The whole process went smoothly; his crew showed up on time every day, kept the area clean, and finished earlier than we expected. Now our kitchen looks completely different—bright, modern, and way more functional. We’ve already had family over and everyone keeps asking who did it. We’re really glad we found Daniel through that recommendation, and we’ll definitely call him again for our bathroom next!"

"The Bedrock team was awesome! Did a terrific job. On time. Most important to me is that they were trustworthy and I felt very confident with them alone in my house. This is the second time Jake has been to my house- the other project was installation of a new wall and door to partition a room off. Also excellent work! Highly recommend!!!"

"Yes! Eduardo and his son did a great job and I highly recommend them to anyone. There’s a lot of contractors who reached out about this project but what I really liked and one of the reason why I hired them because when Eduardo came out to look at the projects he listened and and then he shared with me his thoughts, unlike the others who just insisted this and that and I even almost kicked one out of the house already. After all, we the homeowners are the customers . Anyways, there’s more projects ahead of us and I definitely don’t mind having them to come out for estimate. We showed photos to friends and families and they all loved it."

FAQs for basement remodeling projects in Tumwater, 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.
