"Jon did an excellent job of transforming our outdated, broken bathroom into one that is in showroom condition. The bathroom required more work and time than anticipated and he was at our house everyday putting it all back together. We will have Jon return to our house for future jobs and we highly recommend him for any project that you are considering. Most importantly, Jon listens to and respects women. If there is a problem he will offer solutions/alternatives."

"I recently had my shingle roof replaced and I?m very happy with the results. The team was professional, punctual, and completed the job efficiently. 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."

"So far so good. Kevin the owner of RWL Contracting arrived on Saturday, Jan. 22, 2022 at 8AM promptly. It was very cold and he walked to the back of the property with me to see the basement door from which I told him is the only door his guys will use access the property. When we went inside he offered to remodel the whole bathroom including the ceiling, which I told him he did not have to do. In addition, RWL Contracting/Kevin also was willing to help me with filling out his portion of the RI Living Home Modification Grant page 5. This is a little extra time but would not affect his payment. He explained that his workers work from 8AM- to 4Pm and would not make a mess. Kevin is awesome. He gave me a ballpark quote of $15,000 for a full remodel of the bathroom and told me he would be able to do the work in about a month and a half from January 22, 2022. I am looking forward to working with him, he is very professional. I showed him the tiles I would be using and told him I need one grab bar in the shower and one near my toilet. I also offered to show him my basement from the inside so he could see where his guys would be working from as secondary work space, he said he didn't need to see it. I called him on Friday, February 4, 2022 to ask him if he could please email the quote when he is done preparing it. He agreed. So far, so good!"

"We recommend, without hesitation, Tom Lopatosky and all of those from LOPCO Contracting who worked on the transformative exterior revival of our recently purchased East Side home. When determining which contractor to go with, there were three things integral to our choice - ease, quality and value. As the job required not only paint, but also moderate carpentry work and a new seamless gutter system; we frankly did not want to be coordinating with two or three contractors' schedules, etc. LOPCO Contracting addressed all items for the house, making the process so much easier. The balance between quality and value can be quantified in many ways, especially when quotes vary so wildly. Quite simply, we felt as though the job was worth every dollar spent - and we're both quite particular. And while not something we initially considered, we felt it worth mentioning that all those who we worked with are great guys - a sentiment also shared by our 22-month-old daughter (the greatest of all tests). In summation, LOPCO Contracting was everything one could ask for - competent, consultative, thorough and trustworthy."

"Mario did a great job painting our top floor apartment on the East Side of Providence. The apartment is lofted with skylights exposed wooden beams, so the painting job was complex work that required a lot of edging. Mario did very precise work quickly. He also was able to recommend a high-quality ceiling paint."

"The job was done quickly and efficiently and both buildings look great. Some minor over spray was taken care of and cleaned quickly. We would hire them again for more painting in the future."

"The clapboard on my house is the original wood from when the house was built in 1925. So you can imagine the sanding and prep work that needed to go into the project. The paint job looks incredible The results as well as the pricing exceeded my expectations. I would highly recommend JMC Painting Company. Very honest, clean and reliable. Very happy with the work and I am now using JMC for interior paint projects"

FAQs for addition to existing structure building service projects in Woonsocket, RI

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.
