"Ilya and team were great! Communication was timely and constant. Ilya is a hard hard worker and made our master bathroom amazing. He took out our tub and single shower and installed 2 shower head bathroom with heated flooring, floating vanity, and another light above the shower. He is respectful of our home and a dog person for sure! He left everything nice and neat and went through thoroughly to ensure he did not leave any dust or debris past his working hours. Would recommend to friends and family! Easy, much cheaper than our other quotes and he did it all within our agreed upon timeline! Please use GASHIN and support local!"

"Before we initially hired Johnson & Sons, we were careful about due diligence and spoke to their references.  When we completed that first project, we were very pleased, so we echoed the earlier references and spoke about how well everything was handled.  When we had another small project, we went straight to Johnson & Sons, and again are very pleased with their work.  Vic is an excellent communicator and leaves no stone unturned, keeping us fully up to date with respect to scheduling.  Vic’s relationships with the subcontractors make the entire process seamless.  So if any of you have been frustrated by workers that are AWOL, or by unwelcome changes in scope, or by inferior results, go straight to Johnson & Sons to solve all those issues!"

"Since I now need to use a wheelchair, several doorways in my home needed to be widened. Two exterior doors had to be replaced, one of which also had to be changed to open out rather than opening in. I hired Johnson Custom Builders and was absolutely delighted with their work. They were always professional. They laid or hung plastic sheeting to contain the dust they created, then at the end of the day they ran the vacuum and even mopped the floor! They were respectful of me and my home. Their work was excellent. One of the things I most appreciated was Ryan Johnson's communication with me before, during, and at the conclusion of the project. He listened to what I needed and then figured out how to make it happen. I recommend Johnson Custom Builders highly!"

"We worked with Renovate from August 2024 through April 2025. Our experience was exceptional. Ross, Eric, and Jeremiah were efficient and effective, treating our project with great care. The Renovate team stands out in several ways: - Their pricing is transparent. We paid an hourly cost and subcontractor costs, plus a fixed mark-up, which aligned incentives. Amanda provided receipts and timesheets regularly. - They have superb attention to detail. They pointed out issues we might have missed and ensured they were fixed. - They were super responsive, encouraging us to text or email any time and often responding quickly. They kept us updated on the timeline and explained any delays. - They have a strong client focus. They addressed subcontractor errors quickly and reminded us to ask for what we wanted, even if non-standard. They provided recommendations but let us make the final decisions. We highly recommend the Renovate team. For our more detailed review, see Google."

FAQs for basement remodeling projects in Monroe, 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.
