Andy and his teams have surpassed our expectations on every project! We feel fortunate to have such a valuable resource to better make our house our home. We hold Andy in the highest regard due to his attention to detail, integrity, craftsmanship, and follow-through. We know our renovation projects will be completed on time, on budget, and with beautiful results! We highly recommend Costello Builders!

We highly recommend Costello Builders for any and all renovation/remodeling projects around the house. We have trusted and relied on Andy, the owner, for many years for multiple projects - and his work has always well exceeded our expectations. Some larger projects have included: - New stairs/railings to the 2nd floor with hardwood floors in the upstairs foyer; - A total master bathroom remodel; - Installing a heated tile floor in our family room; - Replacing our back deck and building benches to match; - A roof over the deck, complete with lighting and fan, that flows perfectly out from the existing roofline; - Enlarging our barn; and - Building a “She” shed. Andy has always worked (patiently) with us to understand what we thought we wanted done, and then creatively designed and artistically built the perfect solution. We will always check first with Costello Builders on any further projects. And, again, we highly recommend this company.

Andy has been our families go-to guy for anything construction related for many years. He's never let us down. The last two big projects he did for us, was the complete overhaul and reconfiguration of the front wall of a commercial garage, to allow for oversized doors to be installed. He also finished my father's basement and installed new flooring on the first floor. We operate a small business, where people are always asking us for contractor recommendations, something I don't like to do, but I have always been confident when giving out Andy Costello's name, because I know he will take good care of the client.

Costello Builders has done several home improvement projects for us, and they all have been excellent. Andy is responsible, reliable, and we recommend him highly. His attention to detail is exceptional and we wouldn't consider any other contractor for future work.

Andy is an incredible builder. He’s done multiple projects for me and they all turned out great. Anything you can think of he can make a reality.

Andy's first project was our back deck in 2021. His attention to detail, pride, and craftsmanship in the job, made it an easy decision that we would hire him again. We did glass panel railings and added gorgeous lighting. About a year later we hired him to renovate 2 bathrooms. He guided us to a great local cabinet and local tile company he has worked with for years. Both companies that apply the same level of detail as him. He always adds a creative touch that improves the functionality, and was willing to work with my creative ideas too. In my kids bathroom, we put a lot of thought into getting the right placement for shelving in the shower and we have a motion-sensored under vanity lighting (to light the floor) to act as a night light. Every time I walk in the bathroom I think it just looks stunning. We will definitely hire Andy for future projects.
