"Very high quality work in a timely and professional manner. Will absolutely come back for future projects around the house. Thank you!"

"I’ve worked with RET Construction on a few different projects now, and they’ve been fantastic every time. The owner, Kevin, is always great to work with. He’s professional, punctual, and genuinely mindful of the client’s needs and wants. His crew pays close attention to detail, making sure everything is done correctly and, most importantly, to code. They also kept me updated every step of the way, which made the whole process stress-free, and they always left the job site clean and tidy. I wouldn’t hesitate to use them again."

"This is THE company to use. I had an old 1907 wooden house sitting on a decaying brick foundation and needing a sister foundation installed and a complete seismic retrofit. Even during the bidding process, Brad from Alpha was extremely attentive without being assertive. I contacted four other companies although one I eliminated since they charged a fee for inspecting. Alpha was very timely with their bid and flexible when I needed help with the budget. All the way through the process, every single person at Alpha was extraordinarily good at customer relations, returned emails immediately, and stayed in constant contact throughout the entire process. Whenever there was a slight change to the original plan due to permitting or a plumbing adjustment, Alpha was very proactive and made sure everything was communicated clearly and promptly. I have really NEVER worked with a company that had such excellent communication skills. This is really one reason I selected them to do the work and, even though they may not have been the least expensive, it is worth the extra price for this reason alone. And Alpha Structural's work speaks for itself as well. Everything was done precisely and well beyond code, an unbid section of foundation was provided under the front porch without increase to the budget, and all materials used were of the highest quality. The project went on somewhat longer than estimated due to permit changes and a short weather delay but was still finished in a timely way. My home is our family's largest asset and it is a great relief to now know it is sitting on a solid foundation. The entire process from first to last was excellent and I cannot say enough good things about the way Alpha Structural handled the project. From the front office to the boots on the ground: A++"

"Leo was very helpful and quick to respond. We’re happy with how our 2 bathrooms turned out. Project was completed within the time promised. Our only complaint is that the workers did not clean up very well. But overall, we’re satisfied and we’ll use them again."

"The team was respectful of my property and worked diligently to ensure that the project was completed within the timeframe and budget we had discussed."

"Prompt, competitive prices, small extras at no cost, neat work. Kept area clean. Small amount of splatter on fences.... totally understandable."

"Was contacted directly by Phil quickly after submitting my info. He was at my house the next day. We had him transform our kitchen and bathrooms. He was very professional and prompt with communication. He worked with my wife on all the materials and textures and even finished 2 days earlier than quoted. Very happy with the services and will use Ramapo again!"

"Jorge and his brother Andy were very responsive and professional through the whole process. We had a complicated ADU and expansion to the main house and they did a great job. Very communicative the whole time. Will be using them in the future!"

"When the Project Consultant, Armando Sandoval came out to inspect the foundation, he actually crawled under the house and took pictures of our foundation. He also measured the house to see how far the foundation had sunk. I have had other construction companies come out and no one else crawled under the house. I felt he was very professional in the assessment of our sinking foundation. The project manager Isaac Stern constantly kept me updated with the process and procedures of the foundation repairs. I was very impressed with the respect the crew had for my property and landscape. I would highly recommend this company to anybody. They had excellent customer service."
