A Lifetime of Memories

They stay ahead of the field by continuously introducing new, trendsetting products, backed up with a transferable limited lifetime guarantee.

Nicolock is Local, and Proud of It

Nicolock is 100% U.S. owned and operated, with facilities, retailers and contractors covering the Mid-Atlantic and Northeast regions of the United States. The company prides itself on their responsive service, terrific product availability and superior on-time delivery.

The Latest Color Technology

Need inspiration for that elegant front entry or backyard paradise? Just take a look at Nicolock pavers and wall systems. They have more color choices than anyone in the industry. Their products are warm and vibrant the moment they arrive at your home and will stay looking that way year after year.

Their superior color blending means that your finished project will have various tones, not defined blotches here and there. With their proprietary manufacturing technology and unmatched color blending, you can be sure of a smooth installation process. Unlike some other brands, Nicolock’s color extends through the entire paver, not just the surface layer, ensuring the most vibrant color available in the market!

The Paver-Shield™ Difference

Nicolock’s patented Paver-shield™ manufacturing process delivers a paver surface that is tight and dense, not coarse and grainy like some other products. More importantly, Paver-Shield™ ensures that the aggregate needed to give the paver its strength is never exposed, giving you years of “it looks like new” enjoyment. And all Nicolock pavers have color from top to bottom, ensuring a lifetime of beauty and protection. Iron oxide pigments are guaranteed not to fade.

“I highly recommend Exterior Source for your roofing, siding and decks. They perform quality work with the utmost professionalism. The behavior of the sales and construction managers are one definitely dedicated to serving the customer.”

L. Reynolds Jr.

“They installed new gutters and wrapped the trim and soffit. The job was performed on time and professionally. I am now having them install shutters to match. I would not return business unless I was completely satisfied.”

R. Jankowski

“We have used Exterior Source for the installation of our new leaf guard gutters and replacement windows for our entire house. We had fairly quick service. When the installers arrived, they were very efficient. They left our home the way they found it. We are very pleased with them, and we plan to use them a third and fourth time. They are not the cheapest, but you have to play for quality.”
