C. Costello Masonry Inc.

We just had our chimney grinded & repointed & added flues to the chimney top, and replaced lead flashing. Colm’s team were great; on time, clean & very easy to deal with. Would definitely recommend.

Excellent work on a very challenging brownstone project on both the exterior and interior. Colm coordinated the work to deal with rainy weather and multiple changes in scope. The end result was great and I'd be pleased to work with Costello Masonry again.

I hired Costello Masonry to replace my very old front stairs and walkway. He was very professional when he gave us a quote. He started the job earlier than he thought he could and finished early. This was awesome for us because we had a tough timeline and he called and asked if he could start early because he had an opening. We were thrilled. His crew was courteous and professional and very good at what they do. My front stairs and walkway went from an eyesore to a showpiece. I priced out my job with a few masons and Colm met us and suggested a few options and prices. He was right on everything he had suggested. I highly recommend Costello Masonry. They do A+ work and I'd hire them again without hesitation. A 10 out of 10 company. Colm also either answers his phone or calls you back in a t

Colm Costello Masonry did an excellent job with a chimney rebuild at our 115 year old home in West Roxbury. From the moment we met him (referred by a neighbor), he was clear in his communication, explanations, and discussion. Everything was documented clearly in a contract. The work was actually conducted ahead of schedule. Great craftmanship by his crew from beginning to end. I highly recommend him!

Colm Costello and his team responded quickly and professionally to my inquiry for service to my chimney during one of the coldest weeks of this winter. Within a matter of days from me calling he was at my house and the work was completed in a professional manner. I would highly recommend Costello Masonry.
