"This was a huge effort, especially with working through Jefferson County permitting processes. They worked with architect, engineer, soil, surveyor, and then did an amazing job on the construction. They found phenomenal matches to existing materials, including fireproof wood siding to match existing. The finish work, especially Tile and cabinet install were phenomenal."

"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."

"Fantastic high-end and quick basement remodel. 1250sf added to the house in total, took 4mo to complete from initial meeting in mid-July to finished product 1st week of November 2024. Very happy with the result and strong communication. Rich helped pick out finishes for the home and presented color/material options as well."

"Mark cleaned and stained my deck across the back of my house. We had to work out a day for the staining due the rain, snow and schedules. The deck turned out great, I am very pleased with the job Mark and Nathan did. Kathy from Arvada"

"I reached out initially to have my roof replaced. After a few consultations. We expanded to Gutters and exterior house painting. I have been in the home since build. I inquired about the replacement/ repair of a few windows in the back that the wind had roughed up. We decided to revisit the whole project. In the end We moved forward with the Roof, Windows, Painting and gutters…it was a no brainer. Yes, the PRICE was obviously a factor. However, the seemless transition, communication, execution(completion and look) was the WIN. I’m not usually a person who makes changes like this let alone all at once. However, having ONE contractor and a local team went along with the results satisfaction."

FAQs for addition to existing structure building service projects in Castle Rock, 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.
