What People Are Saying
“My husband and I were looking to redesign our new home. A friend of his told us about Greenport Construction and I am glad we decided to try them out. They came to the house on time, offered us advice on the best way to make the house better. The workers were hardworking and very knowledgeable, and the design looks awesome. Our home looks wonderful. I am so impressed with this company.”
— Wendy K.
“I asked Greenport Designs to bid on moving a bathroom. The bid itself was good in terms of amount, but what impressed me most was the careful way it was broken down between each section of the job for both materials and labour. I knew exactly what I was paying for and what I was getting I ended up not moving the bathroom but repairing the old one, a smaller job and one they finished perfectly. Each step was done thoroughly and neatly and the whole job was finished a day earlier than originally quoted. Even more surprising was the response of my tenant who complains every time I let a repair person set foot on the property. He was so impressed by the quality of the work and the considerate way they behaved that he sent me an email to compliment them!”
— Carol C.
“I had a fence and gate that I wanted built and I was super nervous about it and had no idea who I should call. I was referred to Greenport through a friend and I could not be happier with the work they did.”
— Brandi S.
