Working with Jim is fantastic. He is all about giving the customer what they want. Jim pays attention to all details and is extremely proud of his work, he gets in the dirt with his guys or on his own and works to produce a beautiful product. I needed him to remove and replace the apron around the foundation and a the wall to be repair, which all looks great, he has responded promptly and taken care of the issue immediately and at no additional cost. I highly recommend Jim and Celtic Masonry.

We had a great experience with Celtic Masonry for our chimney rebuild. Owner, Jim Bresnahan was a pleasure to work with. He explained all the specifics of the job beforehand and sent a detailed quote. He completed the job in a timely manner and delivered everything as promised. Jim clearly takes great pride in his work. Don’t hesitate to call Celtic Masonry if you need a mason!

We recently had Jim rebuild our 130-year-old front porch wall from the ground up, also replacing the porch surface with bluestone and installing granite curbing and stone paths on permeable gravel. We're thrilled with the results, and hope this will now last a few hundred years more.

Jim was great. Came out three times to review the project and let us know what he thought and could be done. Had many masons say the job could not be done, but Jim did it and it came out awesome. Already asked him to install spark arrestors on my chimneys. Highly recommend.

Jim called back within a day of me requesting an estimate and came by a couple of days later and followed up with a written estimate by email. He knew immediately what had caused my front steps to fail. He started the work in a week or so. I was please that he offered me some choices and what would cost more or less. He was able to use most of the existing brick and stone. He updated me each day on how the project was going. Jim was great to work with and did a fabulous job. I would recommend Celtic Masonry without reservation.

James is very professional, I check others for an estimate and none other companies did, Celtic Masonry was the only one to come to my house and gave me an estimate, the job was performed perfectly and on time... h I asked questions and he answered all of it, and explain what was the steps and materials that he was going to do... I will recommend to all....

All aspects of the job went as well as it possibly could. The carpenter patched the roof so one couldn’t even tell a chimney had ever been there. The large metal chimney was removed without incident. The gas fireplace insert needed to be cut out so as to preserve the brick encasing the fireplace and the wood mantel. Jim then expertly installed the electric fireplace, doing a beautiful job both solidly securing the new fireplace and making sure the presentation of the fireplace was perfect! It was a pleasure to see someone take meticulous care throughout the entire job, which included thoroughly cleaning up afterwards.

My backyard had a failing timber wall that the previous owner had propped up with posts, and had allowed it to lean into rapidly deteriorating shed. Jim's crew came in, removed the shed and timber wall, and also removed an intact but inadequate stone wall extending from the backyard to the street, a total distance of around 40 feet. He replaced that entire length with a beautiful split-faced masonry wall and poured a new concrete walkway to improve access to the backyard. Jim is the ultimate professional. He takes great pride in his work, loves to talk masonry and answer questions about the project, and is very transparent about pricing. The walkway was an add-on to the original project scope due to some unexpected circumstances uncovered during excavation, but he explained this at length and took photos so I could see why the additional work was required. I would not hesitate to hire him again or recommend his services.

Jim was fast and responsive while other contractors were not returning my calls. He was able to assess the situation and recommend a plan of action to fix water leaking into the house from an old improperly installed concrete walkway. While the project had a lot of unexpected twists and turns, Jim was great through the whole process, keeping me informed of what they found, and how they could go about fixing the problem. The work was done quickly and was top notch quality. We are very pleased with the results and best of all, no water is now coming into the house!

Detailed explanation and discussion of work required to replace steps and landing of the 150-year-old house. Very professional, detail-oriented, and aesthetically appropriate for the house and the needs of the occupants. Masonry was completed in a timely manner. Photos to show results will be added soon.

Celtic Masonry was my 2nd hire off of Angie's List so I had high hopes based on my 1st experience. I'm happy to say I wasn't let down! Jim was great and easy to work with. His initial response to my pro quote request was within a few hours and we scheduled a time to meet within a few days. After initial visit, Jim came back a few times to discuss the project with me as I was still trying to figure out what I wanted. Once I decided on a project/design, he sent me a formal quote (very reasonable and competitively priced - I had 2 other quotes to compare to) within 48hrs and I agreed to move forward. Jim told me I was slotted in for mid-June...by end of 1st week of June, Jim reached out to let me know he'd be starting the work the following Monday. As promised, they arrived bright and early! The work was also completed on time. Work came out beautiful (and I’m picky!)!! Jim was great to work with, anytime I reached out to him I’d have a response within 24hrs. I’m already getting ideas about my back steps and I wouldn’t call anyone else! Thank you Jim for such great work!
