"I hired Topaz Remodeling to replace my front porch, including tearing out the damaged surface, installing a proper drain (the original builder’s oversight caused major leaks), and repairing the resulting damage to the floor, hardwood, and basement. The owner’s communication was excellent, keeping me informed about schedules and progress. They even finished ahead of the estimated timeline. Omar, the project lead, was phenomenal. His recommendations elevated the final result, and his attention to detail was unmatched. The tilework is flawless, with precise measurements ensuring a polished look. The team delivered exceptional quality, turning a stressful situation into a seamless process. My new porch is beautiful and fully functional. I highly recommend Topaz Remodeling and will gladly use them again for future projects."

"We chose Gold Remodeling after talking to a few contractors, and I?m glad we did. They seemed more organized and realistic from the start. The basement remodel stayed close to the original timeline and budget, which doesn?t always happen. The crew worked hard and didn?t cut corners. It?s not perfect, but it feels well done and worth the investment."

"Ryan and his team did a great job on our basement remodel. Communication was strong as was attention to detail. A concerted effort was made to keep the worksite clean. Like many renovations, it took longer than anticipated and we encountered a measurement hiccup that, while solved, could have been identified and addressed upfront"

"Highly recommend Lopez Bros Construction for any remodeling and major home repairs. We completed major home repair and remodeling, including bathroom shower repair and remodeling, Kitchen and Living Room ceiling/internal skylight enhancements, Interior and Deck Painting, and Basement Remodeling. Ray has been always going above and beyond in delivering the results. He will make sure the details and end results are perfect. His team's integrity is unquestionable, responsiveness and quality are top notch. Given the multiple projects he's dealing with, his crew still manage to get the repairs and remodeling done on time, as promised. I would hire Lopez Bros Construction again for my next project."

"Professional, courteous, reliable, honest, hard working, thoughtful and everything you want in a contractor. I have worked with many companies but I have never been this impressed. First of all, the owner is great to work with. He showed up everyday to make sure everything went according to plan. He was very meticulous and brought out a structural engineer several times to make sure that things were done safely and we wouldn’t have any problems down the road. He always had great ideas and what I appreciated was that he wasn’t always trying to upsell you and had cost in mind because re-modeling projects always have unexpected surprises. Gashin took our outdated downstairs and completely changed the look of our home into a stunning modern home. They took out all the tile flooring and installed new hardwood floors, took down several walls to make an open concept space for our kitchen and dining room, refaced the fireplace, installed a new island and countertops for the kitchen, and all the small things involved in a renovation like ours. To add, they did all this in about 6 weeks. I appreciate how our project was not in conjunction with others which helped to make the whole process super timely. Yes, there was dust but they covered everything up and made sure that the zone was clean every night. After getting to know the owner and his crew I had zero reservations about giving them full access to my home."

"After being let down by an unprofessional contractor, we were honestly feeling discouraged—until we found Chase and Anyvision Home Remodeling. From the very beginning, Chase brought back our hope and confidence. He listened, cared, and treated our home like it was his own. The transformation—from the new roof and custom deck to the beautiful kitchen and bathroom remodels—was done with such care and attention to detail. It finally felt like someone was on our side. We can’t thank Chase enough, and we wholeheartedly recommend Anyvision Home Remodeling to anyone looking for a team they can trust."

"I had an outstanding experience with Anyvision Home Remodeling on my master bathroom remodel. Chase and his team were incredibly professional, reliable, and communicative, demonstrating true craftsmanship and attention to detail. In addition to the master bath, they also rebuilt a guest bathroom shower that had been poorly done by a previous contractor, and the difference in quality was remarkable. Their dedication to excellence exceeded my expectations, and after a frustrating experience with another contractor, it was a relief to work with a team that is both highly skilled and trustworthy. I highly recommend Anyvision Home Remodeling for anyone looking for a stress-free, top-quality renovation."

FAQs for basement remodeling projects in Sammamish, 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.
