Meet the Business Owner

Dennis G.

Business Owner

I began working with masonry in the 1980’s and have been enjoying it ever since. I take pride in having complete control of the outcome of all projects and being directly involved in all aspects of my business. I pay great attention to detail and feel one of my strong points is seeing all projects how I would want them done in my own household. I look forward to hearing from clients and giving advice, and the satisfactory completion of a job. I am always in touch and reachable if any questions arise.

Dennis did a Great job rebuilding our brick mailbox column!
He was on-​time, considerate and very reasonably priced.
He also called me back the same day that I initially called him. 4 others never returned my call at all.
He’s also a nice guy.
I would hire him again without hesitation!

A nice guy that’s easy to work with and is very reasonably priced. He got the job done in a timely manner and it looks fabulous. We have more on our wish list of projects and Dennis will be the one we call.

We recently had Denny rebuild our brick column mailbox structure. Denny did an excellent job from start to finish. He gave us a fair estimate and completed the job on time.

Dennis was a pleasure to work with on our chimney stone veneer project.
He was personable and knowledgeable in all facets of masonry trade. Our project did take a bit longer than anticipated, but it was mostly the initial wait time while he worked through his previous jobs elsewhere. Once the work was underway, communication was good and his associate Mark and he did great from start to finish.
Most impressively, he was the lone mason who did climb up onto the roof for the estimate, in addition to scope out the firebox and flue. We were most thrilled about the «do-​it-​the-​right-​way» approach he displayed throughout the whole process. I am probably an OCD-​type homeowner, so it was a joy to find an expert contractor who reciprocated positively.
In summary, he did great work at a competitive price, and we will certainly use him for future work.

We had a leak in the brick on the front of our house. I was given a few cards from the Brickyard in Concord. Within 24 hours, Dennis came out to our house to quote the job. Within a week the brick was gone and the new stone front complete. Dennis’s work looks amazing! Look forward to using Dennis for future masonry work.

Our chimney façade was pulling away from the house and became a safety hazard. I called a few masons in the area and Dennis returned my call promptly and gave me a very reasonable estimate. Dennis just finished rebuilding the façade and fixing previous work that had not been done correctly, and he did a wonderful job. He was also a pleasure to work with, responsive and answered all my questions. I’d highly recommend him.

I hired Denny years ago to put brick work combined with rock around our pool. The work far exceeded my expectations. He was always on time, we knew what to expect by when and he delivered with a great attitude. His work is solid and beautiful. I later had him refinish the inside of my fireplace and again, he worked hard, stayed in budget and on time.

I approached Denny in regards to helping me have some brick pillars put up around my yard. After we discussed the price and I was happy with it, we moved forward. Upon completion of the project, I must say I am very impressed with not only the attention to detail, but also the finished result!

I recently hired Dennis to come in and fix a fireplace job that the original contractor didn’t install properly. The job involved sealing some large gaps between the fireplace stone and the installed glass doors on the firebox. The original contractor left huge gaping holes and smoke was pouring into the house whenever we had a fire burning. Not good.
Dennis came in with a great «can do» attitude and spend a half day fixing the problems the other guy left for me to deal with. When he was finished, the fix was both effective and aesthetically pleasing to look at.
This wasn’t the first job Dennis has done for me. About ten years ago, he refaced a fireplace in another home I was living in. We were going for a stream stone look and it came out gorgeous. People always oohed and ahhed when they saw that fireplace.
I have known Dennis for over 30 years now and I know him to be honest, forthright and fair in all his business dealings. Plus he is a master craftsman at his trade. His work is just gorgeous. If you’re thinking of hiring a masonry contractor, look no further than Dennis!
