Ram Construction & Home Remodeling
Ram Construction & Home Remodeling
RAM Construction is an owner/operator business. My customers expect to see me on the job, not a sub. I truly enjoy what I do for a living and am fortunate enough to live that dream.
"We hired Rich with RAM Construction to complete a major renovation to our property. With my husband being a contractor himself but having no time to do the work, this was a big step to take on our behalf and we needed a contractor we could trust to show up and complete this major renovation. Rich took the job on knowing full well what challenges may exist with working at another contractorâ s home. Rich was completely open to my husbandâ s suggestions as well as being able to provide his own ideas on how to complete the project. Even though we had a contract Rich has been very accommodating with allowing us to veer outside of the project specs. Rich has been great to work with and we recommend him 100% to anyone who may be looking for a great Contractor."

"We bought our first home this year and absolutely love it, but we quickly learned it needed more TLC than we realized. We could see rot on our exterior trim and clapboards, plus a missing gable vent. From the very beginning, Shawn impressed us. His estimate was incredibly thorough, and it was clear he’s a true professional. As new homeowners, we felt confident putting our home in his hands. We are so fortunate we hired him. Shawn showed up early, worked late, and demonstrated meticulous attention to detail in everything he did. When we discovered the rot was far more extensive than we thought, he never made us feel stressed or overwhelmed—he walked us through our options, offered solutions, and helped us make the right decisions for our home. The quality of his work speaks for itself, but just as important, his communication, reliability, and integrity made the experience exceptional. We will be working with Shawn for all of our home’s needs. We actually missed him when he left ! "

"Honeycomb helped save our house. As they were replacing our deck, they discovered rot and quickly removed and replaced all the bad material. They also discovered that we had a termite infestation. The issue was in the structure of the house. They assured us everything would be fine and efficiently dispatched all the rot and talked us through next steps with detailed recommendations, involving other contractors. The additional charge to remove the rot was minimal and I would have gladly paid 10x for the security of having a safe house. And just look at how beautifully it turned out. The photos really don't do it justice, when you get to sit out there enjoying a coffee in the morning or actually having a family gathering. It is such a game changer meeting space. Also, and it might seem like a little thing, but its the details that matter. It was really hard for me to get on my deck as a physically handicapped person. Taylor made it easy for me to go outside alone. I love you guys 11/10"
