"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."

"My basement finishing project was seamless. After getting several bids and designs, I went with Will, who meticulously went over everything, through permits, materials, and the overall concept including pointing out things that I hadn t considered that I am so glad I did. The project turned out fabulous with no issues during the project outside of normal expected issues when working with construction. I would hire Will again for any future needs as I always knew what to expect, there were no hidden costs, and changes were flawless."

Customers say: Terrific value

"I highly recommend this company. Fran Garcia, the owner, did an outstanding job on our basement remodel. Every stage of this project went smoothly, from the initial design to the finishing touches. I felt Fran went out of his way to provide excellent value. In addition, he did a great job of communicating with us. He was always willing to answer questions and provide advice. Overall, my wife and I were thrilled with the work, and we would definitely hire Fran again."

"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."

"Steve and his team at westec helped us add an addition to our garage and the results and experience were outstanding. The actual construction took only 3 months which was way faster than I was expecting and everything was done with a very high attention to detail and integrity. We had an unrelated fire happen during the job (a dryer fire unrelated to the work) but luckily the team was there and was able to put it out and save the house from a lot of fire damage. They really went above and beyond. Would highly recommend working with westec. The process was easeful and Iâ m so happy with the results!"

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.
