"We used Gove Restoration to remodel our 1910 Kitchen and downstairs bathroom and couldn't be more pleased with the results of the project and the way Gove performed, from start to finish. Matt Gove handled every detail of the job, and assisted making the plan and executing it. All of the work was performed on schedule, as promised, and with the highest craftsmanship. Village Cabinets were the showstopper and Gove coordinated all the details for the cabinets, installed hardwood flooring, lighting, and a redesign of our former pantry into a new and beautiful space. The workspace was kept clean and organized during the whole period. Gove moved the existing appliances and kept them ready to reinstall. Matt was a hands-on GC, checking on work, keep us up to date on the schedule and any changes, and really proved that he cared about this big investment for us. Gove proved their expertise in older homes and their unique situations, and handled any unexpected condition perfectly. Every single one of the contractors that came into our home was respectful, professional and did great work. We'd highly recommend Gove Restoration and would use them again!"

"RDO did a fantastic job with our kitchen and bathroom remodel, and we couldn’t be happier! From start to finish, the process was seamless, and the results exceeded our expectations. The team was professional and kept us informed every step of the way. They truly listened to our ideas and brought our vision to life. The kitchen looks sleek, with beautifully designed cabinets and thoughtful details. They finished on time, kept everything clean, and made the entire experience stress-free. If you’re considering a remodel, I highly recommend RDO—definitely a 10/10!"

"Timber and Megan are consummate professionals who are timely, hard working and detail oriented. I was very fortunate to have them realize a project that was centered around creating an in-law apartment in an existing space in my home for my father. They worked with me every step of the way which resulted in a collaborative design with a nautical theme. The end result is stunning and everyone who sees it wants to live in it! Thank you Timber and Megan for making my vision a reality."

"Vinny is a very friendly and professional guy who we really enjoyed working with. The quality of his work is excellent- we used him for our sidewalk and refurbishing the rod iron railings. Overall positive experience with him and the final project turned out great! We would definitely recommend him and will be using his services again in future projects."

"I needed to have the old flooring removed and the new flooring put down. They team was very professional. They realized the subflooring was messed up in a section and made sure to stop and communicate so the job can be doone correctly. I appreciated that factor and was able to approve a replacement of the messed up board the great thing was they were still able to finish the job in the time frame they originally stated! I plan to use them for all jobs moving forward. Priced fair,quality work, and friendly and professional!"

"Our project was the residing of a large two story duplex that has been in our family since 1915 that was carrying siding from 1985. Everyone at Alliance was a pleasure to deal with from Keith, our salesman to Sergie the lead installer on our job."

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