"We worked with Dylan on a number of house projects, beginning with a full bathroom remodel. We also had him hang new doors throughout the house and build/install a customer island in a tight kitchen. He has an eye for finish details that tend to be ignored, and we were extremely pleased with the finished products on the entire project."

"Adam did a fantastic job from the beginning to end. He communicated along the way and helped make decisions, giving us various options. We appreciated Adamâ s integrity and excellent craftsmanship. He made our house a home and treated us like family rather than just another customer. We will use Adam for other projects and highly recommend him!"

"Wow! I had the privilege of Bailey helping me with a project to build a pantry and I can’t express how impressed I am with his dedication and craftsmanship. He worked SO hard, all day long, and finished the entire thing in record time. All while having innovated ideas to make the project extremely functional and professional. His craftsmanship was outstanding and his work ethic was the cherry on top. I hope to work with him again soon."

"Working with Will was great. He was the best as far as working within our specific budget, and always brought great ideas to the table. It was common for him to go above and beyond, and when scheduling conflicts came up, he was quick to communicate the plan forward. Anytime I have another project, he s my first call"

"If you're looking for pros who will do outstanding work using high quality materials, then Baker Building Solutions is definitely worth talking to. They redid my family room, putting in a large new fireplace with a beautiful stone surround, walnut shelving with lighting, and custom walnut cabinets. They replaced the top of a pony wall separating the family room and the kitchen with a walnut bar top. Very durable and waterproof. Finally, the replaced my stair railings, banisters, and associated trim. Again with walnut. The result is spectacular and catches the eye of all who have seen it."

Customers say: Terrific value

"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."

"The Double O team was very professional and knows the ins and outs of fine custom home building. Impressed with their ability to make changes during the construction process, their ability to value engineer certain areas of the project and still deliver the aesthetic look we required. Seth has built a large network of reliable subcontractors that help him achieve their timelines, and the quality of work is exceptional. Hope to build another home with Double O at the helm."

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

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
