"My husband and I reached out to the company to repair some rotten boards we discovered on the exterior of the house. We spoke to David who was extremely responsive and quick to set up our services. The crew came a couple days later right at the time they said, the repairs are great quality, and everyone we interacted with was polite and kind. I wouldnâ t hesitate to hire them for a bigger job in the future!"

"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"

"Miguel Tapia the owner was outstanding. He promptly followed up his initial proposal and we reach an agreed upon price. His crew was hardworking, neat and professional. I was impressed with their prep work as the took the old paint down to the wood base. They painted around numerous flower beds without disturbing anything. I was so impressed with their work, I had them repair and paint some wooden shingles on various areas of the siding of my house. Very pleased with the work and the cost."

"Our kitchen remodel went extremely well! We have done several remodeling projects and Custom Home Pro stood out way and above anyone else we had used. Marcio, who is calm and easy going, was extremely easy to work with. In addition to managing our kitchen project, Marcio also helped us design the kitchen on our own, saving money on a designer, & hired an expert cabinet maker. There were also no cost overruns on our project, even when extra work was sometimes unexpectedly required. Our kitchen is beautiful and we are always getting tons of compliments. Thanks to Marcio and his professional team!"

"I hired Solimine to build an addition sun-room and attached deck from a hand sketch of what I envisioned. They were able to create just about exactly what I was envisioning from the sketch. Work was very professional and all the crew were responsive to questions and comments as they arose. They were also willing to work with me on cost and payments allowing me to upgrade from the original sketch. I would definitely hire them again."

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