"Wes and the A2Z team are excellent, and I highly recommend them. We hired Wes to demolish an existing porch with stairs, lay a new concrete foundation, and rebuild the porch and stairs. They did a great job, and the front of our house looks 100% better. Wes is prompt, responsive and reliable, and he is great at communicating by phone and email. Very highly recommended, and weâ ll be using them again for future projects"

"I hired Tom for a renovation. Even though the job was small, I felt Tom gave me the attention he would have given his larger jobs. He is extremely punctual and professional and helped obtaining the building permit from the Town of Eastchester. I would highly recommend Tom to any of my family or close friends that need the services of an architect."

"The work was done in a timely manner, and as I was told we needed to wait to paint the stairs, and that was the last item, i paid in full. It has now been over a year and i keep requesting that they come out and complete the work, and i receive no response. Disappointed."

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