C Costello Masonry Inc

This is the second time I have used Colm and his work is consistent and incredible. Colm came out to look at the job while I was at work but called me from my property to talk through what I would like to do. His price was comparable and competitive with others. Before starting the job, he came over to walk through everything with me again to be sure he and I were on the same page. His crew showed up early and stayed on task throughout the week. Colm met the timeline that he estimated. The cobblestone border and walkway were done very well. He partners with another provider (Bannon Paving) to pour the asphalt. They showed up when Colm was ready and did a wonderful job to finish the project. Almost every person on my street has stopped to compliment his work. I am so glad I used Colm again, and will absolutely use him for any masonry project in the future.

The walls holding back earth on either side of our driveway were built in the 1930s and were beginning to bow inward from the pressure of the earth against them (the driveway is cut into a hill). Mortar had started to crack. Also, the driveway was very narrow and needed to be widened. Colm Costello gave us the lowest of three estimates and impressed us as someone with integrity who cared about the work. He and his crew showed up on the agreed-upon date, and the work proceeded according to the schedule he'd laid out. They brought in heavy equipment when needed to break up the old wall and move heavy stones around, but much of the work was done by hand, and the masons were skilled. They took care to put crushed stone behind the new wall, for drainage, and they conferred with us at key points on questions of design. Some minor additions we asked for were accommodated at reasonable cost. When it came time to repave the driveway they brought in a crew of driveway specialists who accomplished the whole job in a day. Colm came by personally to inspect the work and make sure we were satisfied. We were.

Costello was extremely professional and timely. They replaced the entire front stairs with granite and rock, as well as a retaining wall with granite and rock. They also replaced three stairs with granite and rock leading up to a small area which they paved with interlocking pavers. The job has enhanced the value of my home as well as glistened the curb appeal of the property. The clean up after the job was concise and complete and Costello responded to all my queries in a timely and professional manner. I would highly recommend this company for any masonry work that needed to be done to improve your home. Very happy with their service.

Colm and his team were professional, punctual and great to work with. They did a high quality job on both our front steps and our garage floor. I would highly recommend them to anyone.

The Costello crew were at our house when they said they would be and they worked long days - they did a magnificent job. Craftsmen level work in my opinion. I know that now because I used another provider (to save a bit of money / wont do that again)
with a ton of great ratings and the work they did on my chimneys was horrifying - looked like a child's work.
I would use Costello again without reservation.

They were incredible from start to finish and their quality of work was amazing. Colm was very helpful even when first looking at the job, making great suggestions, and helping me choose the best products for the job. He was slightly more expensive than another quote I received, but I could tell that his quality of qork would make up for that. He showed up when he said, and completed the job in the time he estimated. The finsihed product came out very well. Colm even followed up with me to make sure we were happy with the job. Many neighbors have commented on how great the job turned out and have asked for his contact information. We have work to do in the future, and I will be calling him again without any question.

Work was excellent. They are very busy and the only downside was I had to wait several weeks to get into their schedule but it was worth it. Meticulous and great attention to detail. Stairs look great and I have asked for estimates for more work.

It was wonderful. He did a very good job. I got several other quotes and his price was the lowest, if not the next one up. The price was fair for what he did.

They were very prompt, they came when they said they would. They were very clean, and picked up after themselves. They were very respecful. We do not haev any sidewalks, so they cleaned the street up after they were finished with the project. The price was very fair; I had two other bids and their price was the lowest. Their work was excellent and well done. The wall looked beautiful when it was finished.

I actually recommended him to a couple of other people and they loved him. My experience with him was great. He was doing my front landing and steps, and he ran into a problem with rotted wood underneath and he fixed all that as well, even though he is a mason. He sent out my wrought iron and had a different company come in and had that all done over and he did an excellent job.

I found Colm very professional and friendly. His workers were also very competent and friendly. They arrived on time and began their work. They were here about 1-1/2 days and when they finished the job they left the areas they worked in completely free of any debris and very clean. Colm even returned the next day to remove two additional bags of 'trash' that they were not able to take when the finished the job.
I would highly recommend Colm and his company to anyone who is looking for masonry work that they need to have done. My co-owners also found them all very professional and friendly.

Initially, it was very difficult to reach Colm and to set an appointment with him. However, he did terrific work once he arrived, and he was very professional. We would definitely use him again if necessary.

I was very pleased with the work performed. The walkway looks great. The owner was very involved in the process from start to finish. He was very knowledgeable and listened to my reqiurements. He even recommended a new configuration for the walkway which made a real differance in the finished product. When I drive up to my house and see the walkway I am very glad I found this company. I would definitely hire them again.

I purchased my circa 1875 small single family home in Jamaica Plain in 2007. Buttoning things up for my first winter, I mounted the roof to remove a satellite dish bolted to the cement-parged chimney. I found the only thing holding the chimney together was the parge on the outside. All the mortar inside had deteriorated. I got estimates from three masons to rebuild.
It was recommended that the chimney be brought down to roof-line and rebuilt with new lead flashing as there was leaking inside the house. With several years having now passed, the leak was corrected by the work Colm performed.
Colm's crew completed the job in a day, left the job site clean and debris free, the work is perfectly pointed with a simple corbel, properly flashed, and topped with a stainless steel cap.
I was very pleased with the work, and the cost seemed reasonable. I would use Colm Costello Masonry again.

This was a difficult project, technically and politcally, for any masonry/roofing contractor because the access to the work site was from the roof of a neighboring condo building whose owners had less at stake in the project than our building. Several contractors had declined to bid simply because the project involved a party wall. One major contractor who had performed many extensive restorations in this historical district almost started the job only to be dissuaded by the intransigence of the neighboring condominium building. Costello Masonry not only bid and completed the project in a reasonable amount of time but also successfully navigated the hornet's nest of conflicted neighbors to satisfy all parties. Costello Masonry also brought in skilled experts in roofing and sheet metal work to perform the non-masonry subtasks of the project. Thanks go to Angie's List for introducing this excellent (and perhaps only possible) contractor to our condominium association.

He was pretty great. I don't think there was anything I disliked. He was responsive, very professional and so were his guys. They cleaned up after themselves and everything. They gave a price three times and then he stuck with it. It seems like he really did a really great job. He looked at a couple of different options and helped me figure out which option I really needed which I really appreciated because it all turned out right. I wanted to get a lot done then I decided not to just because it was a little expensive which he did not mind to give me a price any where when I told him. He did the rest of it it all free for me.

NO complaints. Scheduling was easy; the team appeared on the committed day and worked for 3 days until the job was done. There was no debris left for us to clean up and the job was a great success.

Colm as his workers worked very cleanly throughout the project and finished the job quickly once they started. The project started a little later than expected but was completed quickly as soon as they started. It was definitely worth waiting the few extra weeks to have the work completed by Costello Masonry.

Colm did an absolutely beautiful job replacing our seven (now eight) front steps, using granite slabs on top of the steps and Arcadian granite stones artfully set in concrete for the risers and the sides of the steps. He was the only mason we talked to who had creative ideas as to what we might do aside from the usual bluestone and brick, and we've received many compliments since the completion of the project. Colm was professional and pleasant to work with, and always either picked up immediately when called on his cell or got back to us quickly. We recommend him highly and would definitely use him again..

I would hire them again. The chimney looks great. He came by afterwards to collect the check and wanted to make sure we were satisfied.

It was a big job. The crew worked hard throughout the day and did a very good job. i thought they were very professional.
The crew were polite and respectful which helped make this a positive outcome. There were a few additional charges on the final amount that I thought shouldn't have been there but this was a small percentage of the overall cost, which was lower than other quotes.

Very well. Colm was very professional and well in-charge of his crew from start to finish. They arrived promptly when they said they would, and completed the job professionally over approx 5 days during a horrible spate of 100-degree weather interrupted intermittently by thunderstorms. Demo'd old steps and performed some prep the first day. Next several days, continued prep on walls and other brickwork while constructing stairs. Finished up, cleaned up, and did finish work on final day. Workmanship was of the finest quality. No complaints whatsoever. Very, very pleased with the exceptional end result and highly recommend them to others in need of masonry work.

Colm and his crew dismantled and rebuilt the main chimney on the front of our house, repaired a second chimney, installed new flashing, and installed two chimney caps. The work was done in a timely manner, by craftsmen who were distinguished not only by their skill but also their professionalism. The price was fair, and we are happy with the result. Colm and his crew showed up when they said they would, completed the work when they said they would, and cleaned up the yard afterwards. We very much appreciated their politeness and that they did not leave trash or cigarette butts in the yard (as other contractors have done). We also appreciate how Colm patiently explained things to us about the chimney construction and about other masonry projects around our house. We highly recommend him.
