"NWPM was a subcontractor for a bathroom remodel. They were prompt and responsive -- they showed up when they said they would, and did good work. They installed a subfloor, vanity, toilet, shower door, and an exhaust fan with necessary conduit. I don't know about their pricing because they were a subcontractor, but I would hire them based on their responsiveness and the quality of the work performed."

"Jon B and his crew were a delight to work with. I interviewed 4 general contractors and Jon was the most professional, accurate, and focused contractor. He remodeled a bathroom for me, installed exterior doors, and ended up remodeling my laundry room too! The work performed was outstanding and the cost was reasonable. The crew was professional and a pleasure to work with. I even asked Jon to come back after the project was completed to help with another project that he squeezed in his schedule to accommodate me. I would recommend Jon B. Construction to anyone that wants their project completed efficiently."

"James and the Cox Custom Remodeling crew did an outstanding job on my remodel project despite the fact that I changed scope significantly multiple times during the work. The project began with a fairly modest goal to make an exterior covered deck a bit more resistant to wind and rain by adding side walls, but after the initial bid I asked if it would be possible to turn the deck into the equivalent of an interior room that could be used year-round. James presented a number of different options that were cost-effective and could be accomplished without significant structural changes to the house as I wanted to avoid major alterations if possible, and the team was able to deliver a 4-season room in just over 2 months of work (and with several more changes I added during construction) that's perfectly integrated into the original design of the building. The new room has become the focal point of the house. The crew also completed a full bathroom remodel, added several new window openings, and completed some other projects during the ~10 weeks of construction, but the new room is really what showcased the Cox Custom Remodeling expertise and ingenuity on this project. Before and after pictures attached."

FAQs for basement remodeling projects in Oak Harbor, 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.
