"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."

We help homeowners find solutions to home remodeling and construction renovation needs. We have been serving the Denver, Westminster and Arvada communities for over 25 years with the highest attention to detail with our master design concepts. References are available and we pride ourselves on working around your schedule, respecting your privacy and property. We thank you in advance for allowing us to give your home the attention it deserves. As always we provide a FREE initial consultation, then follow up schematic drawings, preliminary budgets, and as-needed 3D renderings to help you make a great decision for your families needs.

"Kelle is a good salesman. Unfortunately that's where the good ends. Today Kelle "terminated" our basement remodel agreement because they were "overbudget and have another project to focus on." We have thousands of dollars of work remaining and he "forfeited" $700 of punchlist left to bill - big mistake on our part. Not only that, but he scammed us out of a $1,500 Facebook promotion to take photos of the project upon completion - since its not "complete" we won't be seeing that credit. There is good news - we can now finish the work to a level of quality that is acceptable - we have fought Kelle every step of the way to prevent them from cutting corners which they describe as "industry standard." If you care about the quality of your project, look elsewhere so you don't end up making the same costly mistake as us - we've worked with many contractors and never experienced anything like this. We hired Kelle because we have a new infant and trusted someone would get the project done."

FAQs for addition to existing structure building service projects in Longmont, CO

Yes, hidden rooms are legal, as long as they meet all local building regulations. If you sell your house, most states require homeowners to disclose full houseplans, which would include any hidden rooms.

If your secret room is a safe room, it should contain a means of communication aside from a cell phone, such as a shortwave radio. You should also have plenty of drinking water, a portable generator, emergency food supplies, blankets, pillows, flashlights, batteries and a first aid kit.

Any time you update your home’s square footage, you increase its value, but a secret room is a niche feature that doesn't rank high on every buyer’s list of must-haves. Investing your money in remodeling more common living areas like bedrooms, bathrooms, or kitchens will have a higher ROI than adding a secret room. Many secret rooms can act as entertainment spaces (think a game room or wine cellar) or quiet spaces (a library or study), so when building your secret room you may want to consider its versatility for when you’re ready to sell.
