"This was no small project and this contractor is not typical... a second floor deck around 3 sides of a 6 bedroom house done in a way I could park a car on the deck. Workmanship was 5 star, worked full days, used quality materials and the fit and finish is beyond our expectations. Phil and his crew are AMAZING!! I only have pictures of the two additional projects, one a storage area and the other an eating area built on top of a tree with a 1.5" gap between deck and tree platform to conform to code. Non better to do business with!"

"<p>We recommend this contractor.</p> <p><strong>Background.</strong>  This was our first project since the construction of the house in 10 years.  We researched the options of wood and metal buildings.  The cost of each was about the same.  However, the metal building was a quicker and durable option. </p> <p><strong>Contractor Choice.</strong>  We chose the contractor due to the price, the interview with the owner, their website, and a testimonial; we visited a previous job site where they did a similar project.  In general, the owner was more responsive and professional than the other contractors.  The other companies seem less professional and some were just odd.  The local contractor business in our area is competitive but not cheap.  </p> <p><strong>Foundation. </strong> Overall, the survey, land clearing, and laying the A/B aggregate went well.  We chose to hire an additional contractor to clear more land to expedite their work and for other projects.  Foundation framing and cement work went according plan.  During this phase, we were very much involved with their work since we need to integrate our other requirements into the foundation.  We needed to run water and power conduits into the foundation before the pouring of the concrete.  In addition, we prepared a portion of the foundation to support an in ground carlift.  All these actions required us to coordinate closely with the construction team.  Though our special modifications may have been a deviation from their standard work, they were more than willing to work with us to accommodate each special request and let us do the portions of the work we intended to do ourselves.  In addition, we were welcome to ask questions and review the work daily to ensure that there were no misunderstandings or incorrect expectations.   We enjoyed working with both the owner Caleb and his site lead, Calvin.</p> <p><strong>Erection.  </strong>We elected to wait 30 days to begin the erection after the pouring of foundation.  The erection went without any major incident. Caleb's crew performed all of the work for this portion, and did so at remarkable speed.</p> <p><strong>Follow-up.  </strong>We required a follow up visit to fix one of the overhead roll up garage doors that came off its track.  The contractor responded within a reasonable time and completed the work without issue.<br /> Overall, we were very satisfied with the entire experience, from bid through construction to completion. We recommend you consider this vendor for your next construction project.</p> <br />"

"I know nothing about construction. M3 is a family owned business and has exceptional reviews, which is why I selected them (after getting several other quotes). This was my first remodel on my first home (which is REALLY old) - I had LOTS of questions, and M3 was very responsive and patient with me throughout the whole process. They took a very family oriented approach with me and I never felt that they were out to make the big bucks with me. When I was designing the remodel, Brian provided me with his recommendations, and M3 did things for me that I didn't even request (like put together a ceiling fan and come up with a better solution to my electrical issue that saved me A LOT of money). They were very fast - in and out within a week for a whole kitchen remodel. I rated them a and quot;Band quot; in quality as some of the tiny 1/2 inch glass backsplash aren't 100% aligned. Also, the countertops were ordered before the cabinets were installed. The backsplash is not noticeable unless I point it out (it's just me being picky). They were absolutely wonderful and I believe I paid an excellent price for what I got. Come time for my bathroom remodel, they will be the ones I call. <br />"

"This is a great company. B3 replaced some siding on the front of my home, damaged from an ice dam. I was worried about the repair due to the location of the damage and the fact that the paint would need to be matched with the rest of the house. Bob was very knowledgeable with all aspects of the building code, home materials, and history of the neighborhood. His team was able to not only replace the siding, but added some additions to ensure that an ice dam would not damage the siding again. His painter was able to match the color to the rest of the house perfectly. Great work at a great price!"

FAQs for basement remodeling projects in Flagstaff, AZ

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.
