Gutter replacement in Denver runs $8 to $15 per linear foot for 5-inch K-style seamless aluminum with 2x3-inch downspouts. Most full replacements on a typical home land between $2,500 and $3,500. You get that as one flat price before work starts, and the number we give you is the number on the invoice.
That's the answer. The rest of this guide covers how the estimate is built, how to check the math yourself, and what moves a home up or down the range. It also covers how Front Range weather shapes the job, what a complete replacement includes, and when we'll tell you not to replace at all. It reflects how we price gutter replacement and gutter installation across Denver, Aurora, Lakewood, and the rest of Colorado.
What gutter replacement costs in Denver
| Job | How it's estimated | Published range |
|---|---|---|
| 5-inch K-style seamless aluminum, 2x3-inch downspouts | Per linear foot, delivered as one flat price | $8 to $15 per linear foot |
| Typical full gutter and downspout replacement | Same method, whole home | $2,500 to $3,500 |
| Removal and haul-away of the old system | Included in your quote | Typically adds $1 to $2 per linear foot |
| First install on a home with no gutters | Same per-foot rate, no removal | $8 to $15 per linear foot |
| 2x3-inch downspouts | Counted with the gutter footage | Same as the 5-inch gutter range |
| Steel, 6-inch, half-round, box, copper | Per linear foot, scoped on site | Higher than aluminum, quoted per home |
| Rotted fascia replacement, wood or composite | Assessed at the free estimate, included in your one fixed price | $20 to $35 per linear foot |
| Gutter repairs, if replacement isn't needed | Time, materials, and markup, one flat price | $100 to $900 |
Larger homes, two-story rooflines, and premium materials push a project above the typical range. A small ranch with short, simple runs can come in under it.
How we build the estimate, and why you get one number
Every replacement starts with a free on-site estimate. We measure your roofline, look at where water is going now, check the fascia, and talk through material and color. From that we build the price per linear foot, then hand you a single flat number for the whole job.
We do it this way because a per-foot rate on its own isn't a price. It's a formula with your footage missing. If a contractor quotes you "$8 a foot" and measures on install day, the total isn't set until the crew is already on your roof. That's when change orders show up.
Measuring first lets us commit. Removal, haul-away, and recycling of the old system are in the number, along with the downspouts. If the fascia needs work, we assess it at the same free estimate, and you get a single, fixed price covering both before any work begins.
How to check the math yourself
You can rough out your own estimate using the same method we use.
| Step | What to count |
|---|---|
| 1 | Linear feet of gutter along every roof edge that drains |
| 2 | Linear feet of downspout, from gutter outlet to ground |
| 3 | Number of elbows, counted as one unit each |
| 4 | Add steps 1 to 3 for your total units |
| 5 | Multiply the total by $8 for the low end and $15 for the high end |
| 6 | Add $1 to $2 per foot of old gutter for removal |
On step 6, a home with 200 feet of old gutter adds roughly $200 to $400 for removal and disposal.
Your count from the ground will be rough, because roof edges hide behind each other. Treat your number as a sanity check on bids, not a quote.
What decides where your home lands in the range
Material. Aluminum is the best value for most Denver homes. It doesn't rust, it comes in 30-plus colors, and it handles freeze-thaw well. Steel costs more and earns it on homes that shed heavy snow off upper rooflines. Copper is a longevity and appearance choice. Our guide to the best gutter materials for Colorado homes goes deeper.
Size and profile. Most Colorado homes were built with 5-inch gutters and 2x3-inch downspouts. That's fine for some and undersized for many. A large or steep roof moves a lot of water fast. Stepping up to 6-inch gutters and 3x4-inch downspouts on those homes is correct sizing, not an upsell.
Roofline, not square footage. Two homes of the same size can carry very different amounts of gutter. A simple gable ranch has two long runs. A two-story with dormers and multiple valleys has many short runs, more corners, and more downspouts. Height and steep pitches add labor and safety time to the same footage.
Downspout count and routing. Downspouts are real footage. More outlets mean more feet and more elbows, and they decide whether water lands away from your foundation or against it.
Fascia condition. Your gutters hang on the fascia board. If it's soft, it gets replaced first. Most of the time we catch it during the estimate, so it's already part of your one fixed price.
Front Range conditions that shape a replacement
National gutter advice assumes mild weather. Denver doesn't have it.
Hail, May through August. The metro sits in a major hail corridor. Dents weaken gutter walls and stress the seal at joints, and a dent that looks cosmetic can separate at the next hard freeze.
Freeze-thaw at 5,280 feet. Denver swings above and below freezing again and again through the cold season. Water in a seam freezes, expands, and opens the gap a little more each cycle. That's the main reason we install seamless gutters. Sectional gutters come in 5- or 10-foot pieces with a seam at every joint. Seamless gutters are formed on site from continuous coil, so joints exist only at corners and outlets.
Heavy spring snow and snow load. Wet spring snow is heavy, and it slides off upper roofs onto lower gutters. Lakewood and other foothills-adjacent areas get more snow than Denver proper. If snow and ice have torn gutters off your roofline before, the usual fix is steel plus more hidden hangers.
Ice dams. Ice dams form when attic heat melts roof snow that refreezes at the cold eave. New gutters alone won't cure them. Attic ventilation, often starting at the soffit, is usually part of the fix. Where it fits the home, we also install heat cable.
Expansive clay soils. Much of the metro sits on clay that swells when wet and shrinks when dry. Water dumped at the base of a wall can move a foundation over time. That's why downspout placement is part of the design. When a downspout alone can't carry water far enough, extensions or a French drain can be scoped as separate drainage work.
Debris seasons. Cottonwood in May, pine needles year-round, and fall leaf drop don't change your replacement price. They do make a replacement the right moment to consider gutter guards, since guards go on after the new system is hung, pitched, and flow-checked.

Repair or replace: where the line is
Many gutter problems are fixable. A few loose hangers, a leaking seam, or a downspout that needs rerouting usually point to a gutter repair. Repairs run $100 to $900 as one flat price. Above that range, replacement is usually the better use of your money.
Replacement starts to make sense when you see these signs, most of them visible from the ground:
- Sagging that comes back after the gutter has been reattached
- Leaks in more than one spot, or a corner that keeps failing
- Standing water that a cleaning doesn't fix, which points to pitch
- Staining, peeling paint, or mildew on the siding below the gutter line
- Gutters too small for the roof, overflowing even when clean
- Gutters pulling away because the fascia behind them won't hold a fastener
If you're not sure which side of the line you're on, we'll usually put both options in front of you: a repair path and a replacement path.
What a complete replacement includes, and where cheap quotes cut corners
| Included in our replacement | Where low bids often fall short |
|---|---|
| Free on-site measurement and downspout planning | Price given by phone, footage measured later |
| Removal, haul-away, and recycling of the old system | Old gutters left at the curb or billed separately |
| On-site seamless fabrication to exact length | Sectional pieces with seams along the run |
| Pitch set for flow toward each downspout | Gutters hung level, holding water |
| Downspouts positioned to direct water away from the foundation | Downspouts undercounted or left dumping at the wall |
| Fascia inspection before anything is attached | New gutters hung on soft wood |
| Cleanup and a final walk-through | Debris left in the yard |
| 2-year workmanship warranty, plus manufacturer material warranties of 20 to 40 years | Vague or no written warranty |
The most common gap in a cheap bid is downspouts. The second is fascia. A gutter hung on rotted wood looks fine for a season and then pulls loose.
Questions to ask before you sign
- Is this a flat price, or a per-foot rate applied after you measure?
- Are downspouts and elbows in the number?
- Is removal and disposal of the old system included?
- What happens if you find rotted fascia once the old gutters are off? With us, the project manager stops work on that section and goes over the options with you before going further.
- Are these gutters seamless?
- What does the workmanship warranty cover, and for how long?
How long it takes and when it can happen
Most residential replacements take one day. Adding fascia work, guards, or drainage can stretch a job longer, and we tell you that before we start. Fabrication happens at your house, so there's no wait on gutters cut to length at a warehouse.
We install year-round, including winter. We do wait for ice to thaw on both the roof and the ground. Ladder safety and protecting your roof come before the schedule.
When we'll tell you not to replace
- A repair will do the job. If the system is sound and one section failed, we'll quote the repair.
- The problem is drainage, not gutters. Water pooling at the foundation often comes down to where the downspout ends. Extending or rerouting it can be the whole fix.
- Gutters under solar panels. We can install them, but they aren't covered by our workmanship warranty, and you should know that going in.
- Large commercial buildings. HOA, multifamily, and commercial projects are scoped per project. See commercial gutters.
Why Denver homeowners choose Fort Comfort Gutters
The number we give you is the number on the invoice. We measure before we price, so there's no revised total on install day.
Crews inspect while they're up there. With the old gutters down, the fascia and soffit are fully exposed, and we tell you what we see before the new gutters go up.
We're locally founded and operated, with offices in Denver and Boulder, and every installation carries a two-year workmanship warranty.
