"Greg did an excellent job with our flooring and went above and beyond our expectations! Others came in and wanted to laminate over the existing laminate flooring in our kitchen. However, Greg did it the right way and removed 3 layers of laminate and was able to save our existing oak trim in the process. He was also very efficient when it came to using materials. I would absolutely recommend Greg for any flooring installation projects!"

"Francisco Garcia did an excellent job finishing our basement. The work quality is excellent. The communication and flexibility throughout the project was excellent. The project finished on time within budget with zero surprises. Any concerns that arose were addressed expeditiously and professionally. I highly recommend Colorado Paradise Builders for your next project. The building inspections were coordinated by Colorado Paradise Builders and passed easily. We learned while talking to the inspectors that we had a gift by using Francisco as a general contractor. They mentioned other people in the business may not provide the level of customer service and professionalism which Colorado Paradise Builders demonstrated on our basement finishing project. I could not be more enthusiastic with a recommendation."

"Mathew did an outstanding job on the porch. I couldn’t be happier. I was really scared that the stone needed wasn’t going to be found. Mathew took the time to find the right stone. There was also a delay due to weather and he stayed communicated. He was also honest with the materials and let me keep what was left of the stone. I was impressed with his craftsmanship and the completion of the job by himself. Usually this type of job other companies need 2-3 people.Overall very professional. I look forward to using Mathew in future home projects."

Addition to existing structure building services FAQs

How far you can push a room depends on the structure you choose. A cantilevered bump-out can extend 24 inches before building codes require its own footing or foundation. Anything longer needs engineered support and a permit. Check local codes or consult with a structural professional before finalizing plans to ensure your design remains safe and compliant.

Most bump-outs are completed within one to four weeks, even with minimal electrical, plumbing, or HVAC work. Their compact size means less demolition, simpler inspections, and fewer weather-related delays compared to a full-scale addition. Your contractor can provide a more precise timeline once they have determined the scope, materials, and permit schedule, but plan on having the extra square footage ready in approximately a month.
