"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."

"The work went exceptionally well. The work was professionally done and completed within the original estimates for time, cost and schedule. The work included repairing of plaster, painting of walls, floors and ceilings. Also a problem with existing shingles on the roof was repaired. Several good suggestions were made and used as to the materials to be used and how to best perform the work."

"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."

"Fine Construction did a terrific job of gut renovating a 1,900sf pre-war unit for my client who purchased the property. Client, and engineer, interviewed 3 contractors we recommended and chose Fine Construction. Project required a major re-design to add a 3rd a bedroom, flooring structure reinforcement, complete systems upgrades, kitchen, baths, millwork, detail finishing -- you name it they did it. Very pleased with the cost estimates, design advice and workmanship details. Processional service all along the way during months of work. Highly recommend Ciaran Strong and his team for any job, large or small. Contact me Bruce.Robertson@Compass.com, Assoc. Broker, COMPASS"

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