"The experience was excellent and the resulting deck is a masterpiece. The Gove Restoration was open and up-front about what we would be experiencing, especially when the original scope of the project had to change due to the instability of the wooden joists to support the composite decking. The workmen were professional and agreeable to slight changes to recently completed sections. They were respective as possible of existing landscaping and removed all debris as they finished each portion.The experience was excellent and the resulting deck is a masterpiece.

"Larry is the first contractor I have ever hired, and I am so glad I found him. He was a pleasure to work with. He did some drywall repair/install, and installed a new door for us. He was always in contact with me, and always updated me completely. His prices were so reasonable. I will absolutely be using him again for any of our home repairs."

"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."

"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!"

"KBK Construction does an excellent job. Top notch work that reflects our vision every time. Easy to communicate with, reliable and punctual. We started with a clean slate in the basement and KBK listened, fulfilled every detail and built an amazing playroom with built-ins, bar, and home theatre.

FAQs for addition to existing structure building service projects in East-glastonbury, 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.
