Mastic / Norandex
Downspouts & Rain Chains
The other half of every gutter system, sized and placed to actually move water away from your home.
A gutter is only half the system. We fit every downspout with the elbows, offsets, and brackets it needs for strength, and we offer rain chains as a decorative alternative for homeowners who want a different look.

Why This Product Is the Best Choice
Engineered for durability. Outperforms alternatives across the factors that matter most.
Corrugated Aluminum
Corrugated downspouts add strength and rigidity compared to smooth panel downspouts.
Correctly Sized
2x3" for most 5" gutter systems, 3x4" for most 6" systems, matched to your specific roof.
Rain Chain Option
A decorative alternative to a standard downspout, installed to hold up through Idaho winters.
Most 5 inch gutter systems use a 2x3 inch rectangular downspout, while most 6 inch systems need a 3x4 inch downspout to keep up with water flow. We calculate the right size and placement for each downspout rather than defaulting to whatever is easiest to install.
Rain chains are a popular aesthetic alternative to a traditional downspout. We have replaced plenty of poorly installed rain chains over the years, and we install them with a process that holds up through Idaho winters rather than pulling loose at the first freeze.
Available Profiles & Styles
Rectangular Downspout
The most common and economical option, sized to your gutter profile.
Round Downspout
Pairs with box gutter systems for a cleaner, modern look.
Rain Chain
A decorative alternative that channels water visibly rather than through an enclosed downspout.
