"After interviewing several contractors for our kitchen and bathroom remodel, my husband and I felt immediately at ease with Matt. His professionalism and integrity shine through the moment you meet him. We initially bid out a modest bathroom and kitchen facelift in an old 1900's farmhouse. With his insight and resources, we were able to completely remodel both in addition to updates throughout the rest of our home (refinished hardwoods, paint, carpet, etc.). We had an aggressive timeline and he delivered on time and kept within our budget (aside from our requested change orders). Matt and his team of subcontractors surpassed our expectations and were lovely to work with. Matt was always available (never missed our calls) and patient with us throughout all the phases of our remodel. All whilst navigating effortlessly through the various COVID restrictions. We also had the pleasure of working with his lovely wife, Jacqui, who guided us through all the design elements. She made the overwhelming task of choosing paint, fixtures, faucets, tile, flooring etc., fun and fluid. She even showed up as we moved into our home equipped with homemade soup for lunch and helped us unpack! We are so grateful for the opportunity to work with Ziebart Construction and highly recommend them! We will be working with them again on future projects."

FAQs for basement remodeling projects in Hillsboro, OR

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.
