What Our Clients are Saying

From the day that we first contacted Carmen Mastroianni, we have been impressed with his understanding of our needs, his responsiveness to our questions, and the amazing quality of his work. Carmen cares deeply about the standards of design and construction. We were particularly impressed by his attention to detail when doing the “invisible” but critical work on the foundation, the framing, the roof structure, and all-important drainage. The finishes are first-class: our family and friends love to visit because they love our new home, as we do.

Carmen can be very confident of his 10-year warranty, because the quality of his work is so high. Solving problems arising during construction as well as provision of service after occupation have been great experiences. Carmen employs excellent trades people who meet the high standards that a client needs and Carmen requires.

We would definitely hire Carmen’s company again for new construction or for renovation.

It has been our privilege to have worked with Carmen Mastroianni. Carmen is a person who, once involved, will be satisfied with nothing but excellence.

Last June, my husband and I undertook a huge building project; we built an inground pool! My husband wanted to complete this project alone, but he found it to be impossible. Carmen was available to help! Carmen has many transferable skills. He is a positive person with a solid background in construction. He has a proven track record of punctual, dependable service and a reputation for impeccable customer service!

His work for us was not to take over the project but to become my husband's arms and legs. He worked hard to help my husband remain as independent and as active in this project as possible. Carmen is a flexible, solutions-oriented team player with many years of building experience. During difficult times, Carmen knew how to maintain a cheerful and positive attitude that was contagious to all the workers around him. He was always willing to work under pressure and he had the ability to adapt to our ever- changing priorities.

Carmen possesses a strong work ethic with an unfailing attention to detail. He takes pride in precise workmanship that consistently results in a quality product. We are delighted to have had the opportunity to work with Carmen on our pool. It is refreshing to work with a man of Carmen's calibre; he is a person with great pride and knowledge for the trades. We proudly give Carmen Mastroianni our highest recommendation.

I would like to acknowledge the professional workmanship that Carmen displayed while installing our inground pool, pool shed and concrete work surrounding our premises.

I am a meticulous home owner who demands the the best from all tradesmen and workers. He paid attention to every detail and discussed all work with us before he proceeded, even the most discreet areas were covered.

We were so happy with his work and price, we had our basement completely finished by Carmen. I would strongly recommend Carmen to anyone who is as demanding as we are.

All the best Carmen you get a double thumbs up.

Carmen, please feel free to use this as a letter of reference for potential clients. Trust in the builder was the biggest selling point for Barb and I when we wanted to build our house.

We were not interested in someone who would not work with us in making all of the decisions required when building a new home. Carmen was very easy to work with.

Carmen provided answers at each level of the building stages and gave professional options when there was more than one choice to be made. He was very meticulous to quality and ensured the sub tradesman provided the same high standards he expected of himself.

We did not know Carmen before we started working with him on our house. He respected our busy schedule by contacting us at every step of the building process and always followed up and did what he said he would do. We would definitely have Carmen build another house for us if we decide to build again.

Carmen.......just a note to tell you how pleased myself and my family are with our new home. We spent a lot of time looking at homes in the area, but the ones we went through just didn't have the attention to quality we were looking for. We thought building might be a lot of work and take up a considerable amount of our time but you stayed on top of the whole process and delivered the results we were looking for.

It was really something to see the custom plans for our home start to take shape and eventually develop into what is truly our dream home.

I'm sure with your abilities and attention to detail, you will be recognized as one of the premier builders in the Niagara Region. If there is anything we can do for you, please do not hesitate to ask. All the best to you in your future.

Phil and I would like to thank you for the excellent job you did in our recent home renovations. Your professionalism, patience and timeliness far exceed all others even when we would change our minds or add something new. We have had many compliments from our friends and family about the high quality of your workmanship and we do not hesitate to recommend you to them all.

During the renovations and having a little one in our home, dust control and safety were of great importance to us both.You kept the debris to a minimum and always cleaned the work area before you left for the day.

Once again, thank you and if you care to, you can use us as a reference in the future. We would inform them what we already know, that you are a true craftsman.
