"Dylan is an exceptional craftsman. I have used him for countless jobs while restoring my 1913 duplex. He was able to manipulate a variety of salvaged materials that I requested to create the perfect complements to the original beautiful wood. Dylan was prompt, fair, and detail-oriented. I would recommend Dylan to anyone looking for exceptional work."

"Fantastic job! Candace is the ultimate pro- she’s amazing! She listened to exactly what I wanted and my vision and provided great recommendations (at no pressure) and she stayed in constant communication. Gio and his team were on-time, professional, and did a great job. Our project spread out over several days and they cleaned up each night and were very thorough. Excellent communication during and after project. Great follow up and minor detail retouching were done immediately and without hesitation. Would absolutely recommend and will be using in the future!

"Z-Man sent Jonathan from JC's Electrical and he did excellent work for us. We needed two replacement switches installed for bathroom celling heat/fan/light units. The previous wiring was done by an amateur and I was very grateful for Jonathan improving the safety of the wiring when he replaced the switches. He didn't even charge us anything extra above the reasonable price quoted for installing the switches. I highly recommend Jonathan and JC's Electrical! We'll definitely contact him for our next project. Fast and friendly service!"

"azco is the most honest and skilled contractor we've ever worked with. After another company botched our brand-new bathroom, Peter and Valdy came in with a fair quote, tore out the damaged shower, and flawlessly rebuilt it using the Schluter system. You’d never know it was redone—they kept everything clean and precise. We later hired them to expand a second bathroom, and it turned out even better than we hoped. Beyond their exceptional workmanship, what sets them apart is their integrity. They never cut corners, were proactive with issues, and truly cared. After a stressful experience with another contractor, Kazco gave us peace of mind and results we love. Can't recommend them enough!"

"We found a speck home being built by Baker Builders. We went under contract just in time to pick out all of the finishes. We worked primarily with Travis, who was great to work with. He communicated well on any changes, delays, or issues. At the time we were building there were several supply chain issues, so we had to make some changes along the way. Travis always provided an alternative or solution anytime we needed to make a change. The house turned out beautiful! We are very happy with our custom home."

"We had a fantastic experience with CMR Handyman Services. Both the bid and the completion time were as promised. Cesar and his crew remodeled our bathroom, including some structural changes to accommodate a bathtub, and also revised two closets. They were timely, did exactly what they said they would, and were responsive, respectful professionals with an impressive range of skills. We absolutely love our new bathroom and highly recommend Cesar and his team to anyone looking for quality workmanship and dependable service. "

FAQs for basement remodeling projects in Longmont, CO

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.
