"I recently hired Erick's Painting Services LLC for a full interior repaint of my home, and I can confidently say they are the best in the business. From the initial consultation to the final brushstroke, their professionalism, attention to detail, and customer service were truly outstanding. The team was punctual, respectful of my space, and meticulously clean — they took great care to protect my furniture and flooring and left no mess behind. The color consultation was incredibly helpful; their expert provided thoughtful suggestions that matched my style and lighting perfectly. The quality of the workmanship is second to none. Every line is crisp, every coat is even, and the finish looks like something out of a magazine. They used premium paints, and the results speak for themselves — my home feels completely transformed. What stood out the most was their communication and commitment to satisfaction. They checked in at every stage, welcomed feedback, and made sure I was 100% happy with the results before wrapping up. If you’re looking for a trustworthy, high-quality interior painting company, Erick's Painting Services LLC is the one to call.

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.

"My wife and I needed to finish our basement to accommodate our growing kids. We had an excellent experience with Everything Under The Roof. They really listened to what we wanted to build and everything was done well, on-time, and on-budget. One thing I particularly appreciated is that the owner was onsite doing the work, and not simply sending a team of workers. We'll definitely be using Everything Under The Roof for any future projects. "

"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!"

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