Dear Dave,

The Official Board of the United Protestant Church of Sydney River wishes to extend our appreciation to you and your staff for the excellent quality of the work performed in the roofing job for the Church Manse.


Ken Jones,



It seems all you hear nowadays is people complaining that customer service is dead, a thing of the past, and that quality is a forgotten concept. Well, we'd like to clearly state that our recent experience in dealing with Marcus at Gentek sure puts those rumours to rest! When we reported that our siding was fading we truly thought nothing would be done about it - pleasant and professional though the contact was. In fact, we had shrugged off the whole idea when Marcus called back to say Dave from Cormack Builders would be out in the next few days to inspect the siding at Gentek's request.

No sooner had Dave examined it, and sent a piece of siding to be examined by Gentek's lab, then arrangements were being made to replace the siding. And the level of professionalism with Cormack remained as high as the level set by Gentek. The siding was replaced in short order by a crew that were excellent at their job, respectful and friendly, and who left the site as neat as a pin afterwards. We are your number one fans - and we have told scores of people how Gentek is a company that lives up to their promises and delivers customer service that can stand as a model for a company wanting to be known as a leader in their market - and one that associates itself with professional renovators like Cormak to contract their work.

Marcus, may we ask you to do one more task for us? I know it is sometimes awkward to forward comments that speak directly to a person's own excellence, but we would like you to forward our email to your senior management so they are aware of the excellent customer service that you provided. We want them to know that you were extremely professional and assisted us every step of the way. They should be very proud to have you as the voice of their company to customers like us. In addition, we'd like them to know how much we appreciate both your professionalism and that of Dave and his crew at Cormack builders, as well as the fact that Gentek is a company that models its values, not just uses pretty words as an advertising slogan.

Many Thanks,

Willie & Kathy Macintosh

Dave and Alfred,

Both Jane and I wish to compliment Cormack Builders for the excellent work carried out during the installation of our windows and the re-shingling of the roofs.

We were very pleased with the guidance offered with respect to window and door choices, the quality of the Cormack's workmanship and the fact that work was completed within the timeframe quoted. The on-site crew were very diligent about daily cleanup, which was very much appreciated.

We anticipate doing additional work with you in the future, and will not hesitate in recommending Cormack Builders Limited to others.

Best Regards,

Bruce Taylor

My kitchen is beautiful. I love my large pantry.

The doors and trim throughout the house were installed and painted with great care. They make the house look so much brighter looking.

I appreciate the care and work that was done by everyone at Cormack Builders. I was not sure what to expect as I would be alone during the renovations. My fears were put to rest from day one. The men who came to work treated me and my home with respect. They worked very hard every day to get the work done right and on time. They helped me in any way they could, and truly worked as a team.

My husband works away and when he arrived home he could see why I was very happy with the new look of the kitchen and the brightness of the house with the new white doors and trim.

We are proud to tell everyone who did the work for us.

Thank you,

Eric and Martha Timmons

Attention Dave Udle

Dear Dave,

Full Kitchen Renovation

I have to write to tell you how delighted I am with the kitchen renovation which Cormack Builders completed for me at the above address.

You submitted a detailed specification following the professional blueprint I gave you, and your skilled carpenters carried the work out with care and diligence. All of them were helpful and considerate while in my house.

It is now a joy to be in my new kitchen and I am very proud of its convenience and appearance. Friends who have come to see it are astonished at its transformation, and green with envy as well.

Thanking you for a job well done: you did not fail me.

Yours sincerely,

Nancy More
