"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 Erie, CO

Yes, you can add a bathroom on a concrete slab, but the crew will need to saw-cut the slab, trench in new supply and drain lines, and then patch the concrete without weakening the foundation. Working with an experienced plumber and concrete pro keeps the structure intact and helps the new bathroom pass inspections.

schedule covers planning, permits, framing, rough-ins, finishes, and punch-list items. 

Larger spaces or extensive plumbing and electrical upgrades can stretch the timeline, while a simple powder-room conversion may wrap up faster. Hiring licensed pros helps keep the schedule on track and the work up to code.

The best location depends on how your family uses the space. An upstairs bath keeps nighttime trips close to the bedrooms, while a first-floor powder room is handy for guests and everyday traffic. 

Think about where plumbing lines already run, how much square footage you can spare, and what layout changes fit your budget. A pro can map out the smartest spot and handle any code hurdles.

With the right planning, you can carve out a bathroom in almost any part of the house. A successful addition requires sufficient space, proper ventilation, and access to plumbing and electrical systems. Structural modifications and adherence to building codes are essential. 

This process demands careful planning and the coordination of specialized professionals who ensure that the new space meets all code requirements and functional needs.

Under specific conditions, adding an extra bedroom can boost home value more than adding a bathroom. Home value is driven by overall configuration, market demand, and functional balance. A new bedroom influences the property’s appeal in different ways, while an additional bathroom enhances living convenience. Evaluating the current layout and market trends determines the optimal choice for maximum value.
