Downspout Installation in Knoxville, TN
Adding an outlet, moving one that discharges in the wrong place, or replacing a run that has been patched one time too many. Measured on site, priced by the foot.
One more outlet often fixes what a bigger gutter would not.
A gutter drains only as fast as its outlets let it.
If water spills over the same stretch every time it rains hard, the run is usually collecting more than its single downspout can clear. Adding a relief outlet gives that water somewhere to go. It is a smaller job than replacing the gutter, and on a lot of houses it is the correct one.
We measure the run, look at how much roof feeds it, and tell you whether another outlet is the answer — or whether what you actually have is a blockage, a damaged downspout, or a discharge problem.

A relief downspout on a run that is carrying more than it can clear.
Relocating one
Moving a downspout that lands on a walkway, a patio, a bed, or against the wall.
Replacing a full run
Crushed, corroded or repeatedly patched runs, replaced outlet to discharge.
New construction
Outlets planned from the roof lines and gutter runs before grading is finished.
Where a downspout should come down
Placement is decided on the house, not from a rule of thumb. What we look at:
- How much roof feeds the runThe section draining into that stretch of gutter, including any wall that sheds onto the roof.
- The fall already in the gutterWhich way the run drains decides where the low point — and the outlet — belongs.
- Where the water can safely goGrade, hardscape, walkways and planting beds all rule places in or out.
- What is already thereExisting outlets, corners and elevations change what a new one has to do.
We do not publish a spacing rule or a fixed number of downspouts per roof. The honest answer comes from the measurements.
Outlet, elbows, downspout, discharge
A downspout is a path, not a pipe on a wall. It starts at the outlet cut into the gutter, turns back to the wall through an elbow, runs down, and turns again at the bottom to release the water.
Every one of those turns is an elbow, and every elbow is a place water changes direction and slows down. That is why we count them — and why we bill each one as a linear foot rather than hiding it in a vague allowance.
Where the water goes after that last elbow is its own subject. If the system is sound but water still ends up against the house, see downspout drainage and discharge correction.
What downspout work costs
Downspout is priced by the linear foot, the same rate as gutter, and each elbow counts as one linear foot. Your total comes from the footage we measure on site and how many elbows the run actually needs.
| What we measure | Price |
|---|---|
| Downspout | $15.25 / linear ft |
| Each elbow | Counts as 1 linear ft |
| Technical Assessment | $350, credited back in full if you move forward |
| Minimum job size | $790 when a site visit is required |
On-site estimates are free for standard projects. See the full gutter cost page and ballpark estimator for the complete breakdown.
If there is rot behind the old downspout
A downspout is only as secure as the fascia and the wall it is fastened to, so we look behind the old one before we hang the new one.
If rotted fascia, soffit damage or hidden water intrusion turns up once we have access, we stop, document it with photos, explain what we found, and issue a written Change Order before any further work.

Downspout installation questions
When does a house need another downspout?
When one run is carrying more water than its single outlet can clear, which usually shows up as water spilling over the same stretch in every storm. Adding a relief downspout balances the load and often solves overflow that a larger gutter would not.
Can a downspout be moved to a better spot?
Yes. Relocating an outlet is common when water is discharging onto a walkway, a patio, a flower bed, or right beside the house. We look at where the water needs to end up before deciding where the downspout should come down.
Do you replace a whole downspout run?
Yes. When a run is crushed, corroded or has been patched repeatedly, replacing the full run from the gutter outlet to the discharge point is usually more reliable than another repair.
How much does downspout installation cost?
Downspout is priced by the linear foot at $15.25, and each elbow counts as one linear foot at the same rate. Your total comes from the footage we measure on site and how many elbows the run needs. Minimum job size is $790 when a site visit is required.
Do you install downspouts on new construction?
Yes. On a new build we can plan the outlets from the roof plan and the gutter runs, so the downspouts land where the finished grading and hardscape need them rather than wherever is convenient.
What warranty comes with a new downspout installation?
A complete new downspout installation carries MI's 5-Year Workmanship Warranty. A localized downspout repair carries a 1-Year Workmanship Warranty. Both are subject to the signed agreement and the scope of work defined in it.
