"We have been wanting to convert our tub to a walk in shower for years. We are grateful that we found Fusion builders. Daniel the project manager and his team made such a masterpiece. All the details and our request are perfectly done. We requested for shower nische, floating vanity & mirror with lights, high tech toilet with heated seat, bidet and more. Working with them is smooth. Great craftsmanship, professionalism and communication. We will hire them again for our future home updates. Highly recommended! "

"I had some projects like repair cedar boards on deck, wash desk, and sand deck. Also replace facsia on house, remove rotted 4x6 cedar functioning as a retaining wall, replace some fence posts, and tear down and remove a gazebo. Eliberto reviewed the work and gave me a detailed estimate and began work within a week. Within four days he had completed the projects. He did an excellent job working efficiently but carefully and if any issues came up(like rotting lumber beyond scope of estimate) we discussed the problems and came up with a solution and then implemented it. I will certainly be calling on him for any future work I have. It was a good experience to work with him and his crew and I highly recommend him."

FAQs for basement remodeling projects in Dupont, 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.
