Seamless Gutter

Spectra Metals is the largest manufacturer and distributor of gutter products within the United States, offering a complete line of rainware products including coil and accessories in aluminum, copper, and steel.
Spectra Metals’ K-style gutter comes in two sizes, 5” and 6” and is made of either aluminum, copper or galvanized steel.
The 5 inch K-style gutter comes with a 2 inch x 3 inch downspout. Our larger 6” system uses a 3 inch x 4 inch downspout.
Our K-style gutters are manufactured and installed on site by a nationwide network of gutter, roofing and home improvement specialists.
Spectra Metals produces and paints its entire K-style gutter coil, downspouts, elbows and nearly 30 other accessories right in its own production facilities, ensuring the customer of a consistency of color and product quality no matter when the product is made.
Spectra Metals offers 22 different colors. Different colors are available in .025, .027 and .032 aluminum and in .018 galvanized steel. Our unique finish resists dirt adhesion, prevents unsightly peeling, has greater color retention ability than other products and is easy to clean and moisture resistant.
Crystal Exteriors LLC only offers .032 gauge gutter to our customer, the thickest aluminum gutter available for residential application.

Like many of you, you employ some contractors that are decent but you have a select few contractors that you would recommend to anyone without hesitation. Crystal Exteriors is one of the latter for me. You get to deal with the owner, Edgar, directly. He communicates very well and is responsive. It was no problem for Edgar to give me an estimate on short notice, and the project was completed exactly as promised without a hitch. If you want a smooth job with personal attention and no drama, go with Crystal Exteriors.
