"2024 basement remodel with AM Leech, including bedroom, office, bathroom, and laundry room. Adrian and Jim and entire crew were friendly, highly skilled, communicative, prompt, and honest. Easy permitting process that they took care of, and all of their sub-contractors such as electrical, plumbing, and drywall were at the same level of high standards as AM Leech. They were willing to troubleshoot, change gears as needed, and were all around responsive to our needs. Highly recommend."

"I had a leaking roof and needed to get a new one quickly. Lo's Contracting had the best bid and time frame. I'm happy with the end result however it was a bit a fiasco. When putting on the roof there was a bad rainstorm at night and only the underlayment was down at that point. Water came in through almost every room in the house. As you can imagine, I was freaking out! However, I was able to get a hold of one of the workmen who called it in and everyone came out that night around 8pm in the dark and rain and put tarps over the entire house. They brought in huge de-humidifiers the next day and had them running for a few days which seemed to dry everything up. (Lo's Contracting paid for the extra electricity that the de-humidifiers used). They also replaced the insulation in the attic crawlspace at no cost. Three years later there was a leak around one of the nails and pipe collar on the roof, which reading up on does happen(not sure if it should happen after 3 years(that's why the B...but) Amadou was quick to check it out the same day I called and then sent someone as soon as their schedule allowed, a couple days. I appreciate them fitting me in to the schedule and responding so quickly and apologetically. They also cleaned my house after all was done. Amadou, the owner, and Marlon and his team were great to work with, friendly and fixed a couple little things that weren't on the bid at not cost. I would hire again - I'm just not doing anything during the rainiest months of the year again!"

"Once again Hillhouse Construction did the job to perfection. What started out as redoing the baseboards turned into adding matching trim on all windows and doors and painting the doors and jams white to give the home a more updated look. I am so HAPPY with the work and I really enjoy showing it off to friends and family!"

"I hired Joshua to do a master bathroom remodel and can't say enough about the quality, professionalism and integrity that he displayed throughout the entire process. Not only was he thorough, skilled, punctual, neat and communicative,, his subcontractors were as well. Joshua treated his trades people with respect and consideration and that was reflected in the work that they did for him on my job. Together they delivered a project that was both on time and beautifully executed. I was an interior designer for many years and worked with a myriad of different contractors. Joshua stands head and shoulders above anyone I have worked with previously and I would not hesitate to recommend Rutledge Construction."

"Rob was excellent. We could not be happier! An old cabinet was removed from the basement to make room for a new tenant’s washing machine/dryer. The cabinet had been used as support for handrails. The cabinet’s removal resulted in no hand rail and a 4-ft drop onto the floor. A safety hazard! Rob, with short notice, designed, constructed, installed a durable, artful solution. Certainly we would use Mt. Tabor Construction again!"

"Val really listened to my request and gave me options that worked within my budget limit. Also, both Val and Moses responded to any concerns with immediate attention. My kitchen remodel was executed in a timely manner and I am very happy with the result. I can tell that they take pride in their work and it shows in the end result. I would have no problem working with them again."

"We had a rental property which we needed to update and remodel the kitchen of. Christian came out and was very professional, respectful and had a ton of insight regarding our project. Wealth of experience between Christian and his father. The work was completed on time and on budget. We truly could not have asked for a better general contractor. I would highly highly recommend Harris and Sons to anyone looking for a remodeling contractor."

Customers say: Terrific value

"I received several bids for my fence project. I was quit surprised to learned most are specialized in the fact they only install the fence. They do not stain their finished work. But of course they have someone they can recommend. I have a small retaining wall that needed shored up and completed. They don't do it, but they know someone they could recommend. Well lucky for me I found Micheal. He gave me a fair and reasonable bid for all the work I needed completed. He and his crew worked on my project in a timely manner. I would recommend MSW Remodeling LLC to others. I plan to use Michael in the future for my other honey do list."

FAQs for basement remodeling projects in Portland, 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.
