Daniel has some really experienced subcontractors in his arsenal and was able to help us achieve a substantial renovation at a very reasonable price. He was flexible as our design plans changed and had good ideas and pushed us to do a couple larger projects that we were a bit uncertain about until we understood how feasible it was to accomplish.

Our team of professionals will meet all your needs from planning, renovations and building new residential and commercial buildings. We know how important it is to stay within the budget, provide quality work in a timely manner.

"I cannot say enough about Aaron Schwarder and Schwarder Construction. We bought a home that had not been updated since 1964. Plumbing included. Aarons crews redid both baths and the kitchen. Beautiful bright Carrera look tile, white counter tops, beadboard, wainscoting. New light and plumbing fixtures. Kitchen went from dark and cave like with fluorescent lights in plexiglass recessed ceiling thing, to raised ceiling, high end appliances, beadboard cabinets and an open to the dining room floor plan. Aaron was not satisfied with the cabinet surfaces and repainted them himself. All custom cabinets. Very important to me is the comfort level of having people working in my home. It can be awkward, to say the least. Aaron's guys are very respectful and always clean up at the end of the day, even if they are coming back in the morning. They were very careful not to let the animals escape. Recently I called the home depot pro desk with some questions about installing a new entry door and the first name they gave me was Schwarder Construction. I was raised to believe that a man's word is his worth. You can take Aaron at his word. 5 stars only because you cannot rate higher."

"It is hard to review this company. The contractor they sent to do my widows was great! His name is Heath Coffield from Coffield construction. So, this company does have great work. However, their customer services outside of the contractor they hired is not great. They will go weeks on end without giving you any type of update and since they do not notate things will, there was miscommunication."

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.
