A constant throughout my 14 year engineering career has been the exceptional service provided by Knowles Industrial Services. We consider Knowles a partner in the restoration projects that we work on together and a valued resource in the restoration design work that we do. I know that I will get an honest assessment of the details that we develop and an accurate estimate of the cost to complete them. This is critical information as we work with parking garage owners to plan and prepare for restoration projects.

Having worked with Andy, Tim and Travis on many projects I can confidently recommend them and be certain that the Owner will receive a completed project with outstanding workmanship, quality materials, and most importantly a final project cost that is very close to the original estimate. With regard to the projects we have worked on with Knowles, we spend more time improving and refining the details than passing change orders back in forth. Whether the project has been bid or we have worked with Knowles from the start, we always feel like we are part of the same team with the ultimate goal of providing the Owner with top quality work within the estimated budget.

As an owner of a company in Maine, I understand the difficulty in finding and retaining qualified staff especially for specialty work. Dan should be commended for his ability to find and retain a knowledgeable staff of project managers and site superintendents. It is reassuring for us to know that when we recommend Knowles for a project that we are going to be dealing with the same group of people that we have dealt with on the last project, the project before that, and the project before that, etc…

The projects on which we work are not glamorous or high profile. They are noisy, dirty, and an inconvenience for Owners and patrons. When the projects are finished, the average person will likely not even know that anything was done. It is the professionalism and drive for quality work within this context that speaks volumes as to who Knowles Industrial Services is.

From the inception of this project almost three years ago working with Bob Kahn Architect and the owners I was looking forward to the opportunity to recommend Knowles Industrial Services. From a product manufacturers viewpoint, Knowles continues to produce outstanding quality through thorough restoration product knowledge and workmanship. Full restoration projects of this magnitude are not common and your level of detail re-creation is superb. As I quite often say, the man with the trowel in his hand can make the big difference in the success or failure ofthe best restoration products available.

Thank you for your continued contribution to the restoration industry.

On behalf of the Board of Commissioners, I would like to take this opportunity to express our sincere appreciation for your work on the Sagadahoc County Courthouse Restoration Project. The professionalism, patience, dedication to quality, skill and knowledge displayed by you and your workmen were outstanding; in fact, I can honestly state that Knowles Corporation is by far the best contractor with whom I have ever worked!

The scope of this project was much greater than originally anticipated and your willingness to assist with problem solving and finding financial options enabled us to overcome that hurdle. And your unfailing courtesy to our employees and citizens; your insistence on maintaining the integrity of your work; and your prompt communications are but a few of the reasons for the success of this undertaking.

We are extremely pleased with the appearance of the Courthouse, and we thank you once again for making this a successful project for the citizens of Sagadahoc County. With best wishes, I remain,

I just wanted to take a few minutes to express my appreciation for the work that your company performed at our Pacolet Hydro Plant recently. I was first impressed with you, when you came on site to view the Penstock and quickly was able to determine the best way to repair the damage. I was then surprised at how fast you were able to mobilize a crew and have them travel over a thousand miles to the site. When the crew arrived I realized that the project had been well planned and everyone knew exactly what their job was. I was amazed that your crew was able to make the repairs in only ten days, which was better than the schedule you had promised. I was also impressed with the crew’s safety attitude, although they were working very long hours there was not a single accident.

In conclusion, thank you for providing a cost effective, quality repair in a timely manner for our Penstock. Your professionalism and your crew’s work ethic should be commended.

The work completed by Knowles Industrial at the Chestnut Street Church exemplifies the craftsmanship they bring to a project and the component elements of patience, precision, and coordination in executing this type of high quality masonry restoration work.

It is a pleasure to have the opportunity to comment on the exceptional work completed by Knowles Industrial on the masonry restoration of the Chestnut Street Church, now known as Grace Restaurant.

When work was begun on the Chestnut Street fa~ade of the building, the three decorative brownstone door surrounds and trefoil window surrounds, originally constructed with bold moldings in the decorated gothic style, had weathered away to almost nothing. With only one remaining example of each molding profile intact or partially intact for the door surrounds, and almost no original fabric to work with for the colonette capitals and trefoil window surrounds, it is an understatement to say that the accurate restoration of these features required patience and attention to detail. The masons studied the building, and working with Scott Whitaker of Building Envelope Consultants, accurately recreated the moldings utilizing Jahn brownstone restoration mortar. This same attention to detail was also employed for the restoration of the ashlar units, the decorative corbel table under the rose window and even the historically accurate black pointing mortar.

Having recently completed an extensive facade renovation due to initial design and construction flaws, I would like to offer our whole-hearted appreciation to you and the Knowles Industrial Services team for the support and professionalism we experienced during the entire project. From the initial planning and pricing to the final days of completing the punch list, you and your team supported us every step of the way.

In addition, your crew was punctual, and pleasant to work with which was important to our community due to both towers being fully occupied during the process. Your foremans ability to work around other contractors allowed this project to be completed in a timely fashion and on budget. We highly recommend Knowles, and would welcome the opportunity to work with you in the future

I greatly appreciate the prompt professional support provided by Knowles Industrial Services Corporation (KISC) in response to the Portland School Department’s request for assistance in making repairs at Portland High School.

I greatly appreciate the prompt professional support provided by Knowles Industrial Services Corporation (KISC) in response to the Portland School Department’s request for assistance in making repairs at Portland High School.

KISC started work in December, 1995 and worked continuously through April, 1996 varying the size of the crew to meet the tight time schedule established for the project. I found KISC to be extremely flexible in meeting our scheduling needs.

KISC personnel on site often partnered with the engineers to design unique and innovative ways to make repairs. Problems were overcome that included inaccessible spaces, restricted spaces, reinforcing requirements, forming and the unexpected loss of grout. The repair team was able to resolve all grout related problems resulting in successful completion of work.

The work performed by KISC involved pressure grouting the clay tile arch floor and roof system and CMU walls in more than one hundred locations. The work in the attic required special staging to protect the existing 1917 ceiling system. Work above the auditorium was in a confined space, approximately three feet in height, between the plaster ceiling system and clay tile arch floor. Other confined spaces included elevator shafts, and inaccessible spaces under the stairs. KISC also had to establish a lock-out/tag-out procedure to work in the elevator shafts. KISC personnel were very knowledgeable in the safe work practices needed to do this work. At KISC, safety is not just something talked about by management. It is practiced in the field.

In closing, it was the willingness of KISC to support the Portland High School repair project, on short notice, with a well trained and experienced staff that enabled the Portland School Department to complete the work in such a short period of time. It was also your willingness to discount your manpower and equipment rates that reduced the financial impact on the citizens of Portland. Again, your assistance was greatly appreciated.

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. . . Knowles is great at identifying and solving problems; they have state-of- the-art equipment; their knowledge is top-notch; and they’re competitively priced.

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. That’s why Boise Cascade turns to Knowles time and again for chimney work, tank linings, pressure grouting and more. Knowles is great at identifying and solving problems; they have state-of- the-art equipment; their knowledge is top-notch; and they’re competitively priced.

With paper mill machines producing eight to ten thousand dollars an hour, downtime is the biggest cost. Knowles excels in completing the job on time… or even ahead of time: when we have a sudden need to speed up the timeline, they have the depth of skilled personnel to meet our demand.

Safety is perhaps the next biggest cost factor. Knowles has always been right out in front in complying with the mill’s stringent regulations. They’ve also performed superbly on work that’s environmentally sensitive. All in all, Knowles gives me the impression that someone’s really paying attention down there!

It is with pleasure that I take a moment to reflect back on the work performed by Knowles Industrial Services for us this past year.

We were looking for a productive, experienced and cost effective team that could perform concrete repair (hand and gunite applications), grout repair (chemical and cementitous), and expansion joint repair. We also needed a crew that was extremely safety oriented, especially in regards to working at respectable heights, over water, with chemicals, and in confined spaces. In addition, we wanted support from the contractor’s home office so that our Company and it’s field representatives were on the same page as the contractor’s home office and work crew. Finally, we wanted not to babysit the work crew-due either to incompetence or poor work ethic.

In reference to the above, we were blessed in all areas with your work. Scott Doucette, as foreman, was a true professional, understanding our needs and striving to meet them all. His experience, technical competence and desire to constantly improve were easily seen in the physical work. But, I often reflect on a time where we had some safety concerns and without hesitation he referenced his on-site OSHA Manual. Never have I had a contractor have such a reference on-site… let alone know how to use it!

I’d be remiss, if I didn’t acknowledge the support of the home office, especially yourself. Regardless of the lengthy drive from your office to our work sites, you made frequent trips, especially at critical periods, to ensure the success of the job.

With continued quality work and of course competitive rates, I look forward to working you in the future.

On behalf of everyone here at HRH/Dunlap we want to thank you for a job well done on the renovations to the exterior of our building. I cannot tell you how many positive comments I’ve received from others within the Lewiston/Auburn community. The renovation truly captured the original essence and stature of this grand old building.

I also need to mention how impressed I was with Barney Stilphen, who managed the job on a daily basis, as well as his crew. Barney kept me informed on a regular basis and it didn’t take long for me to figure out that his first concern was the quality and the longevity of the work product. His attention to detail and making sure that problems were corrected properly was greatly appreciated. I would also like to thank Barney for his concern and creativity in matching the color of the cement stones to the marble stones in the rest of the building. He and his crew did a great job with this detail work.

As you are well aware this project was for the most part completed during the winter months of 2003. Your crew did an excellent job in dealing with winter conditions, jobsite safety, (which was equally important to you as well) and to the needs and concerns of our employees regarding noise issues. You and your crew were very sensitive to the time of day that certain tasks would be done.

Again, it was a pleasure working with you and your company through out the project. We are all very pleased with the outcome of the building. Please feel free to have potential clients contact us or use us as a referral.

On behalf of Dragon Products Company, I would like to thank you and your staff for your superb efforts on the recently completed silo roof repairs. Your crew and office staff worked extremely hard under extraordinarily harsh conditions to safely complete the project without any problems. Coordination with my staff and our engineering group was excellent, and your budgeting and cost forecasting were correct in spite of the complex job scope.

Creative solutions to our unique problems saved Dragon Products Company a substantial amount of money and downtime, which is a critical aspect of doing business in a competitive market.

In summary, we realized up front that this project presented many challenges that would have to be overcome. Working together as a team enabled us to meet those challenges. We look forward to future business relationships with your firm.

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

The two things that separate Knowles from the rest are, one, they bring intelligence and openness to the initial discussion of the project; and, two, they’re extremely reliable. They develop a detailed plan before they begin, and then carry it out to the letter. And they’re always on your side, working long hours if necessary to get a job done on time. From top to bottom, their employees have been with them for years, so we can count on them for a level of continuity that’s rare to find these days.

I want to express my sincere gratitude and thanks to you and the great crew who recently spent over 7 weeks working here at the East Windsor Water Pollution Control Facility. While this may be something that you deal with on a regular basis, this was the first time I have had to deal with the possible loss of an entire building.

What made this project even more challenging was the fact that this building housed critical equipment that needed to be operated while all of your work was taking place. You did a great job of coordinating with the structural engineer and myself as we continued to uncover more issues as we progressed.

“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.”
