What Our Clients Are Saying
I had two experiences with Keith Manca, renovating a condo and a house… I found him to be exceptionally knowledgeable, technical but yet able to explain himself in layman terms.. He also has excellent taste along with creative suggestions. I found his sub contractors to all be top of the line which is reassuring.. But most important to me, Keith maintained his “yes, we can do that” attitude and good humor throughout both projects… He is the BEST contractor I’ve ever worked with…
Keith Manca and his seasoned crew, did an amazing job on both of the additions we did with him over the years. The attention to detail was amazing. He worked very well with the architect, on what was a very involved job. He was always prompt, responsive and available. My wife and I have a future project coming up and KJM is the only choice.
I would wholeheartedly reccomend Keith J. Manca Building Company to anyone in need of a contractor. Keith and his staff have the highest level of professionalism, craftsmanship, and knowledge. He has been incredibly helpful in keeping our home in top condition. All work is done promptly, neatly, and beautifully. It’s a pleasure to work with Keith and a relief to know that he is just a phone call away.
I have worked with Keith over the last ten years on various projects- mostly on historic homes with lots of daunting structural problems and legacy building systems, long overdue for replacement. He has tirelessly and cheerfully risen to every challenge and never failed to deliver the best results. He has great craftsmen and conscientious subcontractors. His projects are always tidy and orderly and managed personally by him. The final results are proof.
Over the past 15 years I have worked on several home improvement projects with Keith and his crew, ranging in size from several thousand to several hundred thousand dollars. I cannot speak more highly of the quality of work he has delivered. His timeliness, attention to detail, and client loyalty are second to none. It’s my pleasure to recommend Keith Manca and his company without reservation to all looking for reliable and quality work.
We had never built or renovated anything before and knew that it would be crucial to hire a builder we could completely trust to guide us every step of the way. After meeting Keith and touring a few of his projects, our choice was easy. The quality of craftsmanship was evident, even in the smallest of details. As we embarked upon our own project, we never could have imagined how much we would come to rely on Keith’s expertise. Hundreds of decisions had to be made over the next nine months. It could have been an overwhelming burden if not for Keith’s constant guidance. Keith and his master carpenters provide an old fashioned service, rarely, if ever found anymore. He took the time to advise us on the various cutting edge materials or products available for our use. Keith has an amazing eye for style, color, décor, landscape and more, which allows him to look at the big picture. KJM’s quality of craftsmanship and service are unparalleled.
KJM Building really is a team of professionals, beginning with Keith himself. All aspects of our project— every detail, change and issue we confronted— was handled with care, diligence and to our complete satisfaction. Keith was always leading each of the sub-contractors and was integrating them seamlessly into the work plan for a high-quality, comprehensive result.
We have worked with Keith for over ten years now on three major projects. The first was a renovation of our historic 1812 Greek revival house, the second a conversion of an old farm building into a beautiful garage and gardens and the third a remodeling of a 1930’s cottage and guest cottage. Keith is an absolute perfectionist and the quality of his work is second to none. He’s fantastic at understanding the broad scope of a project and the smallest design details. Keith always does what he says he will do– and does it well. He has a built a tremendous network of exceptional subs and suppliers, including architects, electricians, plumbers, stonemasons, and tillers. We really, really like Keith’s people and have got to know them well over the years. They are the same team that we have worked with for the past ten years, which is a testament to Keith’s ability to pick good people and build long-term relationships. Most importantly, we just plain like Keith. He’s a really decent chap, who is easy to be with and easy to work with – which makes the project a delight to work on.
Keith has been a customer for several years and we’ve always enjoyed the opportunity to custom mill materials for his new construction projects and renovations. His team produces the highest quality craftsmanship and is extremely professional from project manager down. We’d highly recommend Keith J. Manca building for your next project.
