Back in the 1980’s, the now President of DCI Products was a contractor who went on countless calls to customers who faced issues such as rotted wood on the fascia, foundation damage, internal water damage and clogged gutters. Understanding that all of these problems originated from a clogged gutter he searched for a long-term solution. Not satisfied with the gutter protection that was available on the market, he designed a flexible, durable and strong nylon matrix that would later be named Flo-Free Leaf Guard.

In 1989, Flo-Free became available to the public along with its LIFETIME WARRANTY. There are now hundreds of varieties of gutter guards on the market and there are also many that have also been discontinued, but for the past 30 YEARS, Flo-Free has remained the choice for a long lasting solution to keeping debris out of the gutter.

Flo-Free Leaf Guards are available for all types of gutter styles and sizes. Please contact us using the form below to request your sample of this time proven product.

Will Flo-Free™ Leaf Guard work with my gutter?

How do I know what size gutters are on my house?

To determine what size and style gutter will require you to have access to the gutter. (If you are uncomfortable climbing on ladders we suggest you call a professional.)

The two most common style gutters are the K-style and Half-round as shown below:

Flo-Free Leaf Guard Flo-Free Leaf Guard

To determine the size of the gutter you will need to measure from the back to the front of the gutter mouth or opening. In most cases your measurement will be 5 or 6 inches across.
Please see images below

Flo-Free Leaf Guard

In this example the gutter mouth measures 5 ” across. It is referred to as a 5 ” K-style gutter.

Flo-Free Leaf Guard

In this example the gutter mouth measures 6″ across. It is referred to as a 6″ K-style gutter.

Fascia gutters are similar in look to a K-style gutter. The face of the gutter is usually slanted, but may also have a concave appearance. In California and other Western states fascia gutters are becoming more common.

Custom Sizes will require measurements to be submitted
