"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. He has proved to be reliable, efficient, and fair in his pricing, as well as very pleasant to work with. I am keeping his number as I will definitely work with him again in the future and recommend him to anyone needing framing or deck building services."

"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."

FAQs for basement remodeling projects in Bothell, 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.
