I have been in the service business for over 35 years. Originally from Ridgefield CT - starting out in the moving business, learning the great value of listening and learning from customers during one of life's most stressful times. Eventually moving into corporate sales in Manhattan with long hours of commute and travel and starting a family. In 2004 I decided to explore other professional opportunities where I could have more control over my time, energy, and creativity.

"29 stars. 45 stars. You get the idea. I’ve worked with a lot of different contractors in my life, and Rob and his incredible team were head and shoulders above them all. Meticulous, communicative, kind - delivering work that was on time, on budget, and done more beautifully than we ever could have hoped for. Couldn’t recommend more"

"We couldn’t be happier with our recent bathroom renovation! Carlos was fantastic to work with—he made helpful suggestions throughout the process, including where to purchase materials and creative ways to add extra storage in our small space. The team took the project down to the studs, replaced and relocated plumbing and electrical, and did a meticulous job with the tiling. The results exceeded our expectations—I’m absolutely obsessed with our new bathroom! Carlos and his team were professional, attentive, and a pleasure to work with. We’ll definitely be hiring them for our next renovation."

FAQs for addition to existing structure building service projects in Danbury, CT

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.
