our approach & values

Why clients hire us again and again

While our core services are abrasive blasting, power washing, painting, waterproofing and graffiti removal, the fundamental value we provide our customers is helping them extend the usable life of their industrial and commercial assets.

Our clients invest heavily in their buildings, structures, and equipment. By properly restoring and protecting these assets, we not only enhance their aesthetic appearance, but ensure our customers get maximum return on their investments. Tim McCahill had this big-picture perspective when he started the company in 1978, and it continues to guide us today.

Tim McCahill, Owner

“We aim to leave our customers elated with our work. It’s not a goal, it’s a standard expected to be met on every job.”

– Tim McCahill, Owner

How do we do it?  By never compromising our values:

Safety First, Safety Always

The safety of our employees, your staff, and your property is always #1. Maintaining an impeccable safety record over more than four decades in commercial and industrial painting has instilled deep confidence in our customers who know a McCahill Painting crew is a safe crew.

100%, across the board—we respect your space, your staff, your time, your schedule, and your budget. We carefully manage our jobs so you’re free to do yours—no headaches or handholding required.

What else should you know about us?

There’s a good chance we won’t be your lowest bid.

Cranking out a high volume of projects with mediocre workmanship has no place here. McCahill Painting never cuts corners on safety, results, or service, and our customers have come to know that they get what they pay for—they clearly see the value of working with a company that delivers consistently outstanding results, employs excellent safety practices, offers expert consultation, has a professional crew, and can operate without constant oversight and handholding.

What’s more, we do not subscribe to the bait and switch mentality of showing customers a number they want to see only to make up excuses as to why we need to add to that number after the project starts. Change orders do happen, but they should never be the result of incompetent or deceptive estimating processes that do not respect the customer.

Our proposals take a little time because they are complete, and you can actually rely on them.

The last thing we want to do is erode your trust by giving you an on-the-spot quote without taking time to document exactly what we recommend and how we’re going to do it. Or ask you to sign a two-line estimate that is so vague you have to cross your fingers hoping everyone is on the same page or, worse yet, waste your time by having to ask us to go back fill in details that should have been in the proposal to begin with.
