"Alex and Donavan were very thorough. Discovered more than what we called them for. We originally wanted information on sealing cracks to eliminate cricket infestation coming through cracks in stem wall. We were not interested in repairing foundation rebar which is typical in slab homes in AZ. They were knowledgeable and honest in their evaluation of our home."

"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!"

"J.D.S. Improvements is a company that I can fully stand behind. Their employees are very responsible, respectful, and professional. We had a large TREX deck built and it turned out beautiful. I would recommend them for all your renovations."

"Amanda was really very good!  At first I was very skeptical, thinking why did I pay money to just speak with someone on the phone about my kitchen remodel project... but after just a few minutes of her addressing some of the issues/questions I emailed to her earlier, I knew it was worth it.  It was very clear that she knew her business and she gave me several ideas that I had not even thought about.  I told her that I would definitely recommend her to friends and I will very likely use her again myself for my next home project!

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.
