"Our split unit air conditioner was under performing. Paul performed a thorough inspection of the system. During the process he used his experience and state of the art testing equipment. He kept us informed of his findings and also explained how to consider solutions. The issue turned out to be a build of of pollen and dust deep inside the wall unit. He opened it up and removed every component carefully cleaning each surface and crevice. Paul is very personable and considerate. He took precautions to protect our wall and flooring. He was also attentive to the integrity of all the parts he cleaned. Now the air conditioner is as clean as a new unit. It is efficient, quiet and we are cool again. Thank you, Paul"

RDO Construction LLC is a premier general contracting company dedicated to delivering high-quality construction services across residential and commercial sectors. With a commitment to excellence, our team of skilled professionals combines expertise, innovation, and integrity to build structures that meet our clients' needs and stand the test of time.

"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!"

At Connecticut Custom Creations™, we specialize in transforming kitchens, bathrooms, basements, and attics into beautiful, functional spaces tailored to your needs. We take great pride in helping people build their dream homes, a core value that drives everything we do. As an owner-operated business with over a decade of experience, I bring seasoned expertise to every project, no matter the size. Whether it’s a small renovation or a large-scale remodel, we’re committed to delivering exceptional results with care and precision.

"We hired CTC Creations to renovate our kitchen after reading multiple positive reviews, and we had high hopes for the work Dustin and his team were going to do based on our initial discussions. While Dustin communicated promptly and seemed responsive to our needs initially, unfortunately right after the contract was signed and deposits paid, his initial work and behavior related to our project became very problematic… We encountered multiple issues: Not only did he take advantage of us financially related to an initial electrical project that his sub-contractor did for us (charging us over $400 an hour a simple outlet swap out), but he demonstrated a lack of knowledge on basic construction elements such as how to install a replacement window and LVP flooring, and most disconcerting, he is now refusing to return ANY of $4,000 deposit we have given him, telling us that we will need to hire him in order to get our deposit back. When we tried to resolve the issues, he refused to be reasonable and instead assessed multiple cancellation fees as well as a restocking fee for supplies he had not purchased. We are very unhappy with how we have been treated, and are disappointed with how he and his partner have refused to acknowledge any of these issues and are now inappropriately refusing to return the unused deposit funds."

We pride ourselves on being a unique construction company. Everything Under the Roof is an interior, residential construction company owned by Kim and Jay Spanier. At work we are a husband and wife team, but at home we are mom and dad, so we truly understand the importance of keeping your project orderly and on time, while keeping your family (including your pets) safe. We can also guarantee NO high pressure sales calls, and no crabby, condescending construction guys working on your home improvement project – just our family helping yours! Kim is your main point of contact through the project. She walks you through the construction process, acts as your personal construction jargon translator, and, most importantly, she is the budget master. Kim will help you shop for materials so that you stay on budget. Jay is the jobsite superintendent. He manages the day to day activities of your remodeling/construction project, he coordinates and manages the sub-contractors, and it’s his skillful carpentry that will transform your home. All of our projects work within the existing footprint of your house. What exactly does that mean? Well, in a nut shell, we don’t do additions, and we won’t raise your roof. We find all the hidden, un-used spaces in your house and re-create your floor plan to work for you and your family.

"Kim and Jay are the best contracting group I have ever worked with. Thorough, responsive and always friendly and courteous."
