Price ranges for downspouts & drainage

Researched New Jersey market ranges, gathered from published contractor price guides and national cost surveys in October 2026. They are not our quote: your price comes from a free on-site estimate, and we will replace these ranges with our own rates.

• Aluminum downspout (2x3 / 3x4), installed: $2.50 to $17 per linear foot, typically about $7
• Copper downspout, installed: $14 to $34 per linear foot, typically about $20
• Underground downspout drain line (market reference): $10 to $30 per linear foot, typically about $20
• Unclog downspout (add-on to a cleaning): $25 to $75 per downspout, typically about $50

Aluminum or copper

Material sets the base rate. Aluminum downspouts, in 2x3 or 3x4, are the everyday choice and cover the low end of the table. Copper downspouts start at $14 per foot and run up to $34, because the metal costs more and the joints are soldered or carefully fitted to match a copper gutter system.

Length and number of downspouts

Total footage is what you pay for, and it grows with the height of the house and the number of outlets. A two-story colonial with four downspouts uses far more pipe than a ranch with two. Adding outlets to fix overflow raises footage but often saves money on repairs and water damage later.

Elbows, extensions and outlets

Each downspout needs elbows at the top to clear the eave and at the bottom to turn away from the wall, plus extensions to carry water out. Houses with deep overhangs, bay windows or offsets need extra elbows. Cutting a new outlet into an existing gutter adds labor at the top.

Clearing a clogged downspout

A downspout packed at an elbow is cleared as an add-on to a cleaning, priced per downspout from $25 to $75. Repeated clogs point to a downspout that is too small or a gutter without enough outlets, which is worth fixing rather than paying for every season. See the gutter cleaning cost guide for visit pricing.

Underground drain lines, for reference

The underground drain row in the table is a market range for a buried drain line, for reference only. It is there so you can budget the whole drainage plan if your yard needs water carried farther than an extension can reach.
