Leaf guard gutter installation costs roughly $20 to $35 per foot, as of 2015. This amounts to around $2,500 to $5,000 for the average-sized home. Pricing varies widely among installers and depends on the type and quality of the product installed.
A simple metal or plastic screen covering the gutter costs around 50 cents per foot, while a better-quality guard may cost as much as $25 per foot. The price of installation usually includes the leaf guards, any fasteners used during installation and the labor charged by the company doing the installation. Most installers offer free estimates prior to installation.
