"We had an absolutely fantastic experience with NZ Improvements! From the very first consultation to the final walkthrough, their team was professional, reliable, and incredibly detail-oriented. They listened carefully to what we wanted, offered thoughtful suggestions, and delivered results that exceeded our expectations. The quality of workmanship was outstanding, and the project was completed on time and within budget. Communication was clear and consistent throughout the entire process, which made everything feel smooth and stress-free. It’s not easy to find a company that truly cares about both the craftsmanship and the customer experience, but NZ Improvements does exactly that. We couldn’t be happier with the outcome and would highly recommend them to anyone looking for high-quality home improvements!"

"I recently hired A-Z Contracting and Weslyn for a laundry room build and a bathroom renovation, and I couldn’t be happier with the results. They built our new laundry room from scratch, including all new plumbing, electrical work, and a new dryer vent installation. They also renovated and extended our bathroom, and the finished space looks fantastic. Weslyn and his team were trustworthy, punctual, and extremely reliable throughout the entire project. I felt completely comfortable giving them access to my home while I wasn’t there, which says a lot about their professionalism and integrity. The craftsmanship is excellent, and the attention to detail really shows in the finished work. All of the workers were knowledgeable, polite, and respectful of our home. The project was completed efficiently and to a very high standard. I would absolutely use A-Z Contracting again and highly recommend Weslyn and his team to anyone looking for quality work done right."

"I was looking for a contractor to renovate a 2BR rental property. After meeting with several contractors I had decided to go with HD Renovations. During the walkthrough BEFORE the work started, Dominick pointed out a few things and we came up with a plan for the project. Dominick and his crew showed up on time every day and worked non-stop until the project was completed. The work was excellent! When electrical and plumbing issues came up, Dom found a solution. He was a pleasure to work with. Always responsive to every question or idea. He had great suggestions along the way and really took pride in his work. The project lasted a month when others had taken 6-8weeks and stayed very close to budget even though I had made a few additions to the original proposal. As a landlord I have used many contractors over the years. HD Renovations were the best! I look forward to working with them in the future!"

"If you want sloppy incomplete and incorrect work hire Hilltop. Bill did not use the products contracted for- used less expensive options without telling us - and hardly ever showed up. The job went way beyond promised finish date. Paid the full balance, Bill then left the work unfinished and ghosted us!"

"Exactly what I was looking for, when I hired this company: they “delivered” a good quality product! They were fast, serious and did not overcharge. Yes! I would definitely ask for their service again and absolutely I would recomend them to my friends and family."

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.
