“Costello Construction is an exemplary company in all ways. They provide the optimum building/renovating experience with a combination of excellent work while keeping costs at a reasonable level. We had a complete house construction done by Costello and couldn’t be happier with the outcome. Sean is always extremely professional and knowledgeable concerning his craft. He is very personable to deal with and I attribute this in part to his being the head of a wonderful family. His wife Roxanne is indispensable to the business and is Sean’s right-hand in dealing with customers and answering all questions promptly. Our project was in MA. while we live in Ct. and so I gave Costello Construction complete confidence and trust during the times we weren’t actually anywhere near the job site. My confidence in CC was rewarded tenfold as we got what we were promised. Imagine a company that sticks to it’s price quotes! The only changes to price were when I’d ask for a change in the plan or material.
I’ve done several renovations for family members in Ct. and NY. I was very fortunate to find Costello Construction for the MA. renovation and after my experience I wouldn’t use another company. In fact CC has been back to that house and one other for various projects. Being so far away I just call Sean and Roxanne and they do a magnificent job of attending to any need. I interviewed 5 builders before selecting them and they stood out as the best. Each reference I checked raved about CC. Take advantage of the due diligence I did and don’t hesitate to hire Costello Construction. You will be very satisfied and happy with the outcome!”

“Costello Construction recently finished a complete renovation of the exterior and windows of our very old home in Manchester, MA. My husband and I were naturally apprehensive about this undertaking given that we live currently in South Carolina. Sean and Roxanne kept us fully informed by email, telephone, and photo attachments during every phase of the renovation. The quality of the work is excellent, and you could not ask for a more reliable and diligent group of craftsmen. We would use Costello Construction again without hesitation.”

“I’ve worked with Costello Construction on large and small projects. The attention and focus to detail was great. Their approach seems unique for contractors in laying out estimates in advance then you pay as go; protects both the customer and them. I’ve found all their workers very friendly with a real willingness to make things right. Having a local resource for building on the North Shore was invaluable when building our house. Overall, an extremely positive experience.”
