Verified record
Keller’s Chimney Repair is an Auburn masonry shop led by Paul Keller Jr., a self-described third-generation mason with more than 27 years in the trade. It focuses on chimney rebuilding and repair, repointing, flashing, waterproofing, caps, steps, sidewalks, and basement doors across central Massachusetts. The two Google reviews are detailed and positive. A May 2026 homeowner described a chimney-liner replacement and repointing job, calling the quote reasonable and the work prompt, organized, respectful, and efficient. A repeat customer described sidewalk repair and chimney work completed on time and on budget, with Paul providing delivery updates. Google shows 5 stars from 7 ratings, although the written review history is small. The Massachusetts HIC license 170948 is registry-verified active. The state registry separately lists CSL CS-106080 as expired, while BBB and the website still list that number; confirm which credential applies before signing. BBB reports 65 years in business and names Paul Keller Jr. as owner. Keller’s is a focused fit for chimney masonry, repointing, flashing, waterproofing, caps, and related exterior repairs. Ask for a written scope, verify the active HIC status, and clarify the expired CSL.
A happy customer in Auburn, MA. I can’t say enough about Paul. I contacted him for a quote on a chimney liner replacement and repointing job. His quote was more than reasonable, and he got to work right away. Paul was nothing shy of professional, considerate, timely, organized, and efficient. Paul was extremely respectful of my property. It was obvious to me that Paul has a true passion for his trade and pride in his work. I, without reservation, highly recommend Paul for any chimney repair or liner replacement. Thank you, Paul, for doing such an amazing job!
I am a repeat customer of Paul because of his dedication to complete the job with the highest level of expertise. Last year, I had my sidewalk repaired and last month, I had some chimney repair work. On both jobs, Paul completed each on time and on budget. I appreciate giving business to deserving contractors who put the customer first, treated me with respect, kept me up to date with delivery dates, and was dedicated to not just doing a job, but doing a great job. Thanks again Paul!
