We were more than happy with Knowles’ workmanship on the first project we recommended them for, so we’re now using them again.

When we began working with Knowles at the Rumford Mill years ago, they were the only game in town. Now there are other companies, but there’s really no competition in terms of safety, value, timeliness and quality of work. . .

Concrete repair and coatings work requires a highly-skilled specialty contractor with successful experience performing similar work. Our experience is that there is great fluctuation in the quality of work that Owners receive from repair contractors when using the open bid process. I often strongly recommend to Owners that they work with Knowles, in my opinion one of the best and most reputable repair contractors in New England. Woodard & Curran has 25 years of positive experience working with Knowles, and we have worked together on dozens of successful repair projects serving many satisfied clients along the way. Knowles is also a valuable resource for me when performing condition assessments, by providing practical repair advice and cost opinions. They always get the job done right and at a fair price, and I have found their project management staff and field crews to be an absolute pleasure to work with. I look forward to working with Knowles on many more successful repair projects in the future.
— Jim Sturgis, P.E. Woodard & Curran
