"Excellent communication and very responsive. Also very considerate, including wearing booties in the house to avoid additional footprints on our floors. We would be happy to do business with The Cleaners and Builders LLC again in the future."

"We highly recommend Dede’s Remodeling LLC for any renovation project. The owner, Nanti, recently renovated our master bathroom & we could not be happier with the results. He is professional, reliable, & his workmanship is excellent. He is a pleasure to work with —communicative, respectful, and attentive to detail. When we requested a change to part of our tile floor after it was completed- he handled everything promptly and without issue. We are extremely pleased with our bathroom and would not hesitate to work with him again or recommend him to others."

"This company is fabulous. Renald and his workers gave a great estimate, and did the job flawlessly designing and executing the building of my exquisite patio. He met us at the supply house to help us pick out materials, he took a personal interest. Beside our beautiful patio, I had him redo our fireplace which looks like a work of art! And since the chimney needed some attention, they fixed some problems with the chimney. All work was beautifully done. I recommended this company to friends of mine, and they hired Renald and his crew and got back to me as to how terrific they found his work and the ease it was to work with them. This is how things should be....attention to detail, quality craftsmanship! I'm happy I could submit this review!"

"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."

"The folks at Daddona were very professional and excellent to work with. My wife and I were very satisfied with the job they did. The basic build was actually completed a bit ahead of schedule and any minor issues thereafter were taken care of without a problem. I would certainly use them again and would be happy to recommend them to anyone else that has a need for the services they offer. Stan and Dawn"

"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!"

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