"Josiah did an excellent job on our down-to-the-studs basement remodel, including flooring, doors, windows, trim and a bathroom. He cares about the details and the quality of his work is superb. He suggested great ideas - like a pocket door for the bathroom. He is easy to work with, collaborative, and very professional. He went above and beyond when we had unforeseen difficulties unrelated to his work. We are looking forward to remodeling another bathroom with Josiah!"

"Ian did an entire gut and remodel of our bathroom and we ran into countless other issues that needed to be fixed that were unplanned and he never once complained. He is extremely knowledgeable, kind, and has some of the best work ethic I have ever seen - he shows up, puts his head down, and grinds out some incredible, attention to detail work. One thing I really appreciated was that he swept up and cleaned nightly when he was finished, I can not say enough good things! We will 100000% be hiring him again. Worth every penny! Thanks again, Ian!!"

"You expect a handyman to quote a job and charge to the quote with out add one; you expect a professional job done in a timely manner. Ean of Emery Builders does exactly that. Not just my deck but also he built an 8 X 10 foot shed in ONE day! Painted the entire house and my fence. All to quote! I have had many compliments on all the jobs. I would recommend Ean to anyone. Believe me not all handymen are equal."

He responded to my request quickly, provided me with an estimate the next day. This was done on a Friday and my new deck was completed by Monday afternoon. Fantastic!"

FAQs for basement remodeling projects in Bellingham, 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.
