Testimonials

“For years, our beautiful home, built in 1905, fell deeper into disrepair as we deferred maintenance to raise our family and take care of other necessities. The time arrived when we could no longer ignore the decaying supports of our front porch and the desperately worn siding on our upper story, so we hired Ciaran Mackey of CMAC Contruction to provide the much-needed repairs. What an excellent decision that was. Ciaran and his crew of workers were knowledgeable, efficient, hardworking, and reliable as they addressed the many issues that came up during the repairs. When the pandemic struck, the work stopped for a while, and Ciaran kept us abreast of the steps ahead as he followed the quarantine orders and the CDC criteria for keeping his workers and us safe. When able to start again, we could rest assured that the work was being done safely and expertly. Ciaran made daily check-in visits as the crew progressed with efficiency and skill, and we were able to relax, knowing that everything was being completed with great care. The workers showed up each day before their start time, worked full and long days, and cleaned up their stations before leaving. My husband, who is well known for being a meticulous workman himself, was pleasantly relieved by the high quality of the work. Our house is now restored to its former beauty and strength, and our neighbors often comment on what a fabulous job CMAC Construction did. In fact, several of them have taken Ciaran’s card to request help with some of their household repairs. We are very grateful to Ciaran for the excellent workmanship and integrity shown throughout our restoration project, and we highly recommend CMAC Construction to anyone in need of a qualified and competent contractor.”

Testimonials

“I had the pleasure of working with Ciaran Mackey on a bath remodel in our condominium in 2019. Our bathroom is beautiful, and we are very happy with the quality of Ciaran’s work. Ciaran is capable, honest and takes pride in doing the job correctly. There were especially challenging circumstances with our remodel because our tenant was displaced and anxious to move back in, and we were out of the country for a few weeks. So, Ciaran was under pressure to get the job done, and he had to make decisions on our behalf along the way. Ciaran did not miss a beat, he stepped up and went the extra mile to ensure that every single detail was taken care of. We would definitely hire Ciaran/CMAC Construction again.”

Testimonials

“We hired Ciaran to help rebuild and assist with an insurance claim after extensive water damage to the lower level of our home. Ciaran provided a very reasonable estimate/quote and worked directly with the insurance company to make sure they agreed to the scope and cost. He takes great pride in his work and the work of his subcontractors. He is meticulous and detail-oriented, always wanting to make sure that we were completely satisfied with every choice and (unavoidable) compromise made. The work was completed on budget and we were kept informed about the progress and all the issues throughout the project. We would definitely work with Ciaran again on future home improvement projects.”

Testimonials

“On any scale we would rate CMAC five out of five stars for the work that was done on our house. The quality of work was excellent and the work crew was technically superb, always courteous and prompt. From the beginning of the project Ciaran Mackey, owner, guided us with options to correct dry rot and potentially structural problems at our home.

During the construction Ciaran was on-site always available for questions and we especially appreciated his attention to details. Although it took longer than expected because the dry rot impacted more areas the combination of a Ciaran and his team made the job less stressful for us. Ciaran regularly updated us on the costs and took time to show damage and explain every step before moving forward. Great job, it was nice doing business with you. We would highly recommend CMAC to anyone who needs inside or outside construction work done on their home.”
