Services
In 1954, two major events took place. The first was the beginning of a 50 year marriage between Joe and Rosalie. The second was the start of "Jay Kay Roofing Co.," a small residential business that over the years has grown into what is today "Jay Kay Seamless Gutter Supply." As a contractor, Joe knew the importance of completing a job in a timely fashion, while still providing the homeowner with the best quality building materials available.
Please contact us if you have any questions regarding products we carry or delivery services we provide. We are more than happy to answer your questions. Our office and warehouse are located in Wanaque, right across the street from the main entrance to the Wanaque Reservoir. Please ask for Rob Scott when placing an order.
Our drop-off system allows you to have custom length gutters delivered right to the jobsite along with all of the required parts and accessories. Residential 5" and commercial 6" gutters come in a wide variety of standard colors, with matching leader pipe and accessories. If your project calls for a larger gutter, we carry industrial 7 gutter in white and brown, with 4x5 leader pipe to match.
Whether your project is to renovate a historical property, or to build a new structure with a classic feel, half round gutters are probably what your project calls for. We carry all necessary half round gutter parts in white, brown, copper and galvanized. Also, for the European accent, we carry Berger Bros EuraCraft Gutter System, available in 18 foot lengths.

Product received exactly as described. Received faster than originally promised. And all the free goodies thrown in (pen, contractor pencil, magnet) were a nice touch. Great experience.

Bought a Y-connector for a downspout that had a failing hand-crafted connector in its place. The new one from Jay Kay looks like a perfect fit and the finish is great. Glad to find a small business nearby making exactly what I need. Shipped the same day I purchased it and arrived in short order.

Ah the lost art of customer service isn't lost here. A refreshing and pleasant experience in the current culture of "not my problem." Ordered from clear across the country and had my order shipped with a personal email on a Sunday.

Excellent experience working with Jay Kay on a downspout Y connector shipping to Canada. Super responsive and shipped fast. Highly recommend their products and customer service. And they also included a nice pen and carpenter pencil as a bonus in the package!

I found the Downspout Y Connector from Jay Kay on eBay. Ordered it there. It was fulfilled the same day and delivered a couple days later as expected. While not installed yet, the Y Connector is beautifully crafted seemingly with all the extra attention to detail required for a piece like this to work without a leak. Appreciate the service from this small business.

Local and big-box hardware stores didn't have what I needed, Jay Kay did and I'm grateful I found them. I ordered on a Friday afternoon and had the part Monday (I live in MD). The Y connector was exactly as described and fit the job perfectly. Worth every penny.

I previously posted a five-star review based on excellent customer service, quick delivery and apparent availability of the parts I needed that were not available at local big-box home improvement stores. However, when I went to actually use them, I discovered that the "Downspout Y-Connector _Standard_ Left" was not really standard. At least with the Amerimax "standard" turns I bought at Lowes, they did not line-up exactly.probably 5 or 10 degrees off.

I had to leave additional play in the joints just to overcome the mis-match with still some residual non-straightness in a few joints. The response from the company was (paraphrasing) that they are as-described on the web site and that "everyone" knows their custom "standard" parts are not exact and may need to be tweaked during installation to line-up. OK, so I guess he's trying to say that this is like everyone knowing that a 2x4 does not really measure 2"x4", or, as I found-out recently, that 1-1/2 inch "clean basalt rock" is not really clean and contains lots of fines and dust (my own analogies).

But I would have expected there to be some disclaimer or note on the web site about what "standard" means. Like when I buy HEPA filters for my home air handling unit. I buy "20x20x5" filters, but the web site lists the EXACT dimensions down to the 1/8" so you can tell if it will really fit in your unit. As another heads-up, in case anyone is also trying to do this same thing, the Upright Y-Connector (that my wife called the Saguaro Cactus joint) was also not a perfect fit for my application.

I was using it to go around a gutter so that I could have a second story downspout go around the gutter and directly into the drain, rather than just dump into the porch gutter (which was overflowing). Although not specified or implied, I was disappointed that the "arm" did not extend far enough outward to fully go around the gutter. So I had to deform the gutter a bit so I could get the arm extension up to the second floor gutter.

The customer service from Rob was outstanding! I had to add a section of gutter above my front door and tie into an existing downspout from above. I had no idea what to do, but Rob took the time to use a photo I sent him and put a diagram into the photo and send back to me. I ordered that item's he suggested and showed up quickly to my home. First time ever doing gutter work and thanks to Rob at Jay Kay Seamless Gutter Supply it saved me a ton of money and product and service was outstanding. Oh did I mention Rob worked with me well after normal business hours to ensure I had what I needed. Thanks Rob! Photo attached, house is being painted this week.

Excellent on all fronts. I ordered Jay Kay's Y Connectors off Ebay and it was the most smooth transaction I have ever had with any online company (Amazon included). Within a few hours I had my tracking information and

I can't say enough about how HAPPY I'm with the "Y Connector" I purchased from Jay Kay Gutter Supply. I was combing the internet and I kept finding "Y Connectors" only from some pretty shady over sea suppliers. My tenacity finally paid off and I come across Jay Kay Gutter Supply. I called and spoke to a very nice representative who told me they were a small business and their "Y connectors" were handcrafted right in their shop.

I immediately ordered the part. As you could see from the before pictures I was trying to clean up the prior owners sloppy looking sump drainage pipe and gutter downspout that were ruining the curb appeal on my daughter's new house. I wanted to connect the sump pump drainage pipe and the gutter downspout so we had a nice tidy look. From the after picture you can see I was able to accomplish exactly what I was hoping for. Thank you Jay Kay for helping me with this project. If I could give you more than five stars I would!
