"Jordon and Cam were awesome to work with and our new basement is amazing. We had never hired a contractor before so we were nervous about hiring someone. Wright Brothers took the time to answer all questions, and we had a lot of questions. There communication during the job was great and our new basement exceeded our expectation. The initial price they quoted was exactly what we paid, with the exception of a few upgrades we requested after the project had started. We have already referred several of our friends to them and cannot say enough good things about them."

"This is the second time I have hired Sean, and once again his work exceeded my expectations. Sean is always thorough, detailed and quality focused. His work ethic is beyond reproach. He does NOT speed through the job, but takes the right amount to time to make sure it is done right the first time. You never have to call him back to fix anything. I highly recommend Master MCG Remodeling for any of your household remodeling projects."

"The Basement Company North finished our basement and added a fireplace in our home. The team always kept us notified on the schedule and kept a very clean worksite even with all the construction. They were always quick to respond to our questions and we love the finished work they did. We would definitely recommend The Basement Company North and will be using them on additional house projects down the road."

"Integrity Remodeling Services completed the remodeling of 3 bathrooms and a laundry room for our house. Once we finalized the quote, they were timely and professional. Jim and Carlos were able to help us overcome several unforeseen obstacles during the remodeling projects and advised on bathroom remodeling options. Jim was also flexible when changes needed to occur. Overall, we recommend Integrity Remodeling Services for home renovations, especially when on a budget."

"I chose Emilio with 614 drywall to mud, tape and texture the drywall in my basement. For multiple reasons, his quote was reasonable, his previous work was impressive and he was very timely in his quote and responses to questions. I am so happy that we chose 614 drywall to complete this project. The work was done with pride and the finished product was incredible. Emilio completed the 1200 sqft basement in the quoted time, and worked very hard to do so. I would recommend 614 Drywall to anyone who has ANY drywall needs."

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.
