Testimonials
Words of Appreciation from Our Clients
It is my absolute pleasure to recommend the services of Jason Schneider. From beginning of the project to end I was impressed with his professionalism , attention to detail and recommendations for the highest quality subs on his team.
Jason gave us an extremely detailed proposal and answered my MANY questions throughly & patiently before we even signed the contract.
He is a FANTASTIC communicator, very accessible & was always able to let us know where we were in the process at every step.
Our project was completed on time and to our utmost satisfaction. AND he & his crew kept the worksite extremely clean & neat, something I am VERY picky about, I really appreciated this as well.
I have no reservations giving Jason my highest recommendation. I am confident that you cannot go wrong by hiring him & his team for your project & that you will be very pleased with the end result.
We set out to convert our garage into an ADU. Having never gone through a renovation of any kind before, we were nervous and anticipated all sorts of hiccups, delays, additional costs and just an overall bad experience.
Jason and his crew were so on top of it all. He communicated with us daily. He shows up on site and keeps track of the schedule. We always knew what was coming next. We really love the ADU, it's gorgeous,, the craftsmanship is very apparent. I'm a realtor and see shoddy work often, this is not it. I could not be happier with the results.In a crowded field, finding a trusted contractor is difficult. Jason and his team are the right people for your project! He was consistently available, professional, and knowledgeable. His plans and work were always rooted in our overall vision. He would offer practical, aesthetic advice to us whenever we asked and found solutions for what seemed like impossible requests or ideas. Furthermore, he was never offended or hurt when we did not abide by his suggestions. We fully support Jason and are confident that he is the right choice to help build your dream home. ☺️
As an interior designer, I want to take a moment to commend Jason for being an exceptional contractor!
He truly embodies the definition of conscientious—someone who is dedicated to doing what is right and executing their work with thoroughness and integrity.
Jason is reliable and transparent, consistently meeting deadlines while demonstrating a keen attention to detail and accountability.
Our collaboration on numerous projects has been a pleasure, and I feel fortunate to work with someone who brings such perfect synergy to our projects!
