"Josh and Hometown Construction did a fabulous job on our basement remodel! They were communicative, professional, and showed up on time. All of the subcontractors were also professional and did a fabulous job. Josh regularly came to check on progress of work being done, and he personally took care of any typical construction issues ASAP. They went above and beyond to finish the job to our standards and on time, and they never nickel and dimed us. I’ve already recommended Hometown Construction to friends and family, and I’ll continue to recommend them to anyone looking to remodel their home or basement!"

"We hired Wright Brothers to do our basement remodel that included a full bar, guest bedroom, bathroom, and a lot of custom millwork (i.e built in entertainment center, wainscoting, base trim and window casing). Although we had a design in mind before we hired Wright Brothers, they were able to offer suggestions to improve what we had already started. Their prices were very fair and the communication from the beginning to the end of the project was outstanding. We never felt pressured to do anything and they were always upfront and transparent when items outside the scope of work were identified. Guests are constantly amazed when they walk in our basement and see the before and after pictures. It is a place our family will use for many years to come thanks to the quality, dependability and integrity Cameron and Jordan put into their jobs."

"We hired Matt and the A-Z Remodel and Repair team for our basement remodel, and the experience exceeded our expectations from start to finish. Matt was punctual, professional, and incredibly communicative throughout the entire project. We always knew what was happening and what to expect next. The job site was kept impressively clean and organized every single day, which made living through a remodel far less disruptive than we anticipated. Matt’s attention to detail is outstanding, and it shows in the quality of the finished work. Even when subcontractors were on site, Matt was there alongside them, making sure everything was executed to his standard. The project stayed on schedule, the craftsmanship is excellent, and Matt’s customer-service-first approach made the whole process genuinely enjoyable. We’d hire A-Z Remodel and Repair again without hesitation and recommend them to anyone looking for a contractor who truly cares about doing the job right."

"I worked with Baker Builders on finishing my basement (around 900 sqft, with a full bathroom and a wet bar area). I started the project in late 2019, just before the pandemic. They took the measurements and proposed the layout. Due to the pandemic the project was put on hold. I was very pleasantly surprised that when I resumed the project in early 2021 we didn't have to start from the scratch - we could jump directly to the execution. The basement has been finished according to the plan, and I could not be happier with the outcome. Every detail has been taken care of, and I have no doubts as to the quality of the work performed. Each crew working on the project was extremely accommodating about any smaller and bigger requests that I had during the execution. Travis, who was the project manager, deserves a separate mention. Thanks to him the project went so smoothly. I really appreciated the initial schedule provided by him, and that we actually followed it to a large extent. There was no unreasonable delays, and generally things happened when they were supposed to. I was really afraid the project would drag for much longer, based on previous experiences with other companies, but Travis just made it happen! He was on top of things all the time. He accommodated each of my requests, his responsiveness was truly amazing, and I really have never worked with anyone like this on any other project. In general, Baker Builders did an outstanding job with this basement project. Every aspect of it - the price, timeliness, responsiveness, no hidden cost, no unexpected delays, even accommodating COVID precautions - made this is a very pleasant and smooth experience. This is a very solid 5 stars, and with no hesitation I would recommend Baker Builders to any of my friends (which I already did), or use them for any project in the future."

"I hired 614 Drywall to remove my popcorn ceilings, re-texture and paint. They were timely, professional, communicative, helpful, and did an amazing job. The ceilings look so great! My house looks so much brighter and updated. It’s a messy job but totally worth it. High quality work and I would recommend them to anyone!"

"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."

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.
