"We had a top to bottom, excellent experience with the local team from Universal. My wife and I had an in-home consultation, a measurement and the install completed in a little over a months time. As stated in a prior review, the cost is reflected in the quality of the workmanship. Our family could not be happier with our experience. Big thanks to Kyle, Ron, Mike and Dennis for the top-notch service. I can wholeheartedly recommend Universal Windows Direct to any homeowner in need of a new door, installed quickly and by a friendly, knowledgeable and friendly staff. Thank you again!"

"The project went great; I'm very happy with the final product. It lines up exactly with what I was looking for at the start of the project and looks better than I could have planned because of some great design suggestions from Wagner Home Renovation along the way. We ended up creating two separate closets from the previous closet incorporating some previously unused space in the condo as well. Both closets are accessed through very nice double doors. The laundry closet and general/clothes closet both look great. Wagner Home Renovation used high quality repurposed wood from a previous project and black iron rods to give the general/clothes closet great character. All of the work was very well done, and blends into the existing paint and trim-work so well, you can't even tell any work has been done. As an example, they added a wooden keystone at the enlarged entranceway near the new closets that was a very nice touch and feels like it was always there. They were able to save me money throughout the project by offering to use repurposed wood from previous projects that was often better quality than what would normally be used. Wagner Home Renovation does high-quality work and has a genuine interest in how well the end result turns out. They have a great attention for detail, offer great design ideas and options, and are responsive, honest, budget-conscious, flexible, reliable and easy to work with. I highly recommend them."

"I highly recommend Boyd Builders. My sunroom and deck were coming away from the house. Shawn jacked up both replaced footings, posts and drain pipes. Budget was clear from the start. He is professional and exceptional in his work. I have already recommended him to friends."

"Dana is a true professional with a keen attention to detail. His work started with an exterior door replacement at my house. I liked the quality of work and talked with him more, and decided to have my kitchen remodeled as well. Very happy with the finished projects, highly recommend Dana for any fine carpentry work!"

"Responsive. Respectful. Reliable. MRC Construction did an outstanding job with my new siding and gutters! This was my first big home improvement project. I set a budget, began the research and ultimately requested bids from four suppliers. MRC was the most competitive, offered the product selection and warranty I was looking for and their schedule fit mine. Rodrigo is professional and patient and answered all of my questions. Marco managed the onsite work flawlessly. From the first phone call to the last walk through, MRC Construction is FIVE stars. I highly recommend MRC Construction and will go back to them for my future projects."

Customers say: Terrific value

"The guys were a great team. They showed up on time, communicated well with each other, and cleaned up any mess they made. There was quite a gap of time between when they finished the porch and came back to finish the ceiling (a small part was due to electrical work) because they overbooked themselves, but they kept in contact with me about it and successfully completed the job. Only complaint at this point is I contacted them after the job was done about something I had that went missing, and they never returned my messages. Will be placing a phone call to try and remedy the situation."

"My wife and I needed a new roof on our carport and also the 3 season porch roof. The carport had a hole in the roof and caused rot around the rear support post. Eddie told me what needed to be done. It wasn't a simple job as I hoped it would be. After most of the work was completed, they noticed that there was a lot of rot on the house siding where it meets the roof of the 3 season porch. There was also other rot around the carport roof. Knowing that We wanted to eventually do vinyl siding, we decided now was as good a time as any. The crew did an excellent job on the carport and 3 season room, so we hired them to vinyl side our house. Best decision we ever made. The workers who did this job are top notch, very professional. Cudos to Mike, Matt, Craig and Tommy"
