"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."

"Excellent. We added a bathroom and a bedroom, took down paneling and completely redid the family room. These guys did all the electrical work, plumbing work, flooring, painting and everything else. Amazing communication, stayed on budget, worked very well with us and the work was done quickly and exactly as described. Any issues were immediately dealt with. Any questions were immediately answered. Would absolutely work with these guys again and would recommend them!"

"Timber and Meghan were great to work with. The price for the work was extremely reasonable and Timber was very flexible and creative with solutions. The original plan was to power wash and treat the existing fence and pergola. Timber suggested going over the old fence with a new fence and building a new pergola.The overall cost for these changes was pretty much the materials. We provided Timber with a photo of a pergola that we found on line and he recreated it flawlessly. I cannot praise Timber highly enough. We are thrilled with the new deck. One of our friends is a retired home builder who is never impressed. He had nothing but praise for the quality and craftsmanship of the work. We already have plans to engage Timber for additional projects. PS We had to order a new dishwasher while Timber was here. He installed it for us and took the old one away."

"Abdul Perry and crew did a fantastic job. Diligent workers, meticulous work. Cleaned up at the end of every day. The price was fair. They even took care of the rot around some windows and walls. No hidden fees, no unnecessary work done. We will definitely be hiring them for future projects."

The quality of the work is excellent, and the new roof looks great. They kept the work area clean and communicated well throughout the process. I would definitely recommend them to anyone needing a roof replacement."

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