"A friend of mine who was very happy with their work recommended G&B Carpentry to me. I called on the weekend and had Lamar out on Monday for an estimate. He was very knowledgeable and professional. The estimate was detailed, and the prices were fair. The work began that same week with demolition and new drywall being installed. The work was well done and detailed. The project manager and I had excellent communication, and he kept me informed about the work that was being done. I had a couple areas where I requested some additional work to be done, and they were accommodating to my request. Everything was finished on time and with high-caliber work. I feel like G&B really worked with me as well as for me in the completion of my project. I am very pleased with all aspects of their work and excellent followup to ensure satisfaction. I would highly recommend them and will use them again for any future projects."

Customers say: Terrific value

"I can’t even say enough great things about this company. The owner and his crew were outstanding! Did such a great job on our garage addition. They were so patient and understanding. The owner (Frank) even came with me to the city appeal hearing. A+ communication. Reasonably priced. Would I recommend him to family? He IS family. I am so grateful I found him on Angi’s list and hired him for this project. I highly recommend him!"

"We initially hired Bearded Builders to repair the drywall that was left open after we had plumbers extend our water lines. Not only did the Bearded Builders team repair the drywall, but they made it look seamless! We requested they hang the cabinets in our exam room as well as do other repairs around the office. They are now our Go-To for all things building related."

"We are seniors who had foundation and floor support work done by AccuLevel. Soon after they got paid we started finding more & worse problems arising from their work than what we originally contacted them for. The floors they ?fixed? were not level and started heaving like a roller coaster, many of the doors do not open or close properly, our finished floors are squeaking & popping up all over and the foundation is shifting & leaking more that it originally did. Twice they sent out servicemen to fix the problems by making adjustments; that only made it worse. The last service man said that the problems were bigger than he could handle alone and would set up to have a crew come back in warm weather to make the needed repairs; that hasn?t happened yet. We found out that much of the work was done wrong and not done as per the plan and specifications or what our salesman told us would be done, the materials we were quoted, paid for and supposed to be used were substituted and never instal"

"David and Micah remodeled our master bathroom. They did a fantastic job and provided their opinions when asked. They completed the job a few days early. I would highly recommend Hudson Home Improvement for any remodeling. In fact, I plan to remodel my other bathroom and will be hiring them for that job as well."

FAQs for basement remodeling projects in Portland, TN

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.
