Why Seamless Gutters and Not Sectional
Seamless gutters are custom-fabricated on site from a single piece of aluminum or copper to match your roofline exactly. The only seams are at the corners and downspout outlets, all sealed by hand. Sectional gutters bolt 8 or 10-foot pre-cut pieces together with a joint in the middle of every run, and those joints are where 90 percent of leaks start. Fewer seams means longer service life, cleaner appearance, and a system that survives Northeast Florida's storm season instead of failing in it.
| Factor | Seamless (what Gutter Pro installs) | Sectional (box-store / cheap quote) |
|---|---|---|
| Joints | One continuous run per side, joined only at corners | Caulked seam every 10 feet |
| Leak points | Inside and outside corners only | Every joint, the first thing to fail |
| Fabrication | Formed on site to your exact roofline | Pre-cut factory lengths |
| Sizes | 6, 7, and 8-inch aluminum or copper | Usually undersized 5-inch |
| Service life | 25 to 40 years aluminum, 75-plus copper | Shorter, seams degrade and separate |
| Best for | Every Northeast Florida home | Not what we install |
Sizes, Styles, and Materials We Install
6-inch K-style (the Jacksonville baseline)
The right size for the majority of Northeast Florida homes. Paired with 3x4 rectangular downspouts. Available in 0.032 aluminum and copper.
7-inch K-style (upsize)
For larger custom homes, steep architectural rooflines, metal and clay-tile roofs, and high-volume valleys. Paired with oversized 4x5 rectangular downspouts.
8-inch K-style and box gutter
For estate homes, commercial buildings, and box-gutter architectural applications. Paired with custom-sized downspouts matched to roof drainage area.
Half-round (6 and 8-inch)
Premium architectural profile. Sheds water faster and traps less debris than K-style at the same width. Hung with custom-cut T-wedges shaped on site. Available in aluminum and copper.
Box gutter (7 and 8-inch)
Built-in box gutter design for commercial buildings, historic homes, and architectural applications. Hand-fabricated to match existing detail.
Materials: 0.032 aluminum and solid copper
Seamless runs are machine-formed in commercial-grade 0.032 gauge aluminum with a baked-on enamel finish — the only gauge we run seamless. Heavier 0.040 and 0.050 aluminum is available as fabricated work for box, custom, and commercial applications. 16 oz solid copper with soldered fittings serves historic and architectural homes. More on copper.
Gutter Pro does not install 5-inch gutters in Northeast Florida. They overflow in Florida's high-volume rain events. Anyone quoting 5-inch on a Jacksonville home is undersizing the system by a full inch. Not sure what your roof needs?

The Install Spec That Holds in a Storm
| Spec | What Gutter Pro installs |
|---|---|
| Hanger system (K-style) | Heavy-duty hidden hangers, screwed through the fascia, 18-inch spacing — tighter than the 24-inch maximum we allow on any job |
| Hanger system (half-round) | Custom-cut T-wedges fabricated on site to match fascia profile |
| Spike-and-ferrule | Never. 1950s technology, backs out under thermal cycling. |
| Miters (corners) | Hand-formed, double-sealed, reinforced. No pre-formed snap-on corners. |
| Downspout sizes | 3x4 rectangular (6-inch gutters), 4x5 rectangular (7 and 8-inch), 4-inch round (half-round and copper) |
| Underground tie-in | FDM heavy-duty HDPE — 3.5 and 4-inch solid pipe, 100% virgin resin, rated for vehicle traffic — to a controlled discharge point. Never recycled black pipe. |
| Old gutter haul-away | Same day, magnetic sweep for fasteners |
| Warranty | Lifetime workmanship on every install, plus manufacturer material warranties |
Built as a Complete Water-Management System
Gutters alone don't solve the problem. A 2,500 square foot roof in a 4-inch rain hour produces over 6,000 gallons. Sending that volume through properly sized seamless gutters into underground drainage that exits at a controlled discharge point is the difference between a dry yard and a flooded crawlspace. Every Gutter Pro install is designed with the whole system in mind: gutter sizing, downspout placement, underground tie-ins, gutter-guard strategy, and where the water actually leaves the property.
Underground runs go in as FDM heavy-duty HDPE — 3.5 and 4-inch solid pipe, 100% virgin resin, rated for vehicle traffic, with no glued joints to crack. Florida soil cycles hard between wet and dry; the ground swells, shrinks, and works the pipe. Rigid glued joints eventually crack under that movement, and a cracked joint underground is a leak you cannot see. Schedule 40 PVC has its place — very low slope, bulkhead and seawall penetrations, backfill that will settle — but FDM is the default because it outlasts the alternatives. As an NDS Certified Professional Drainage Contractor, we design that exit path correctly the first time. See our full drainage solutions.
Pair with the Right Gutter Guard
For any home under heavy oak, pine, or palm canopy, a gutter guard is the difference between a one-time install and quarterly cleanings. Two guards earn a place on our trucks, and they solve different problems. LeafBlaster Pro is 316 marine-grade stainless micromesh — the lowest-maintenance option, our default, rated for oak tassels, pine needles, and shingle grit, with a 40-year manufacturer warranty. Alu-Rex DoublePro is not a mesh at all: it is a continuous hanger with a double-layer aluminum guard that structurally reinforces the entire gutter run — our pick for coastal homes and anywhere strength is the benefit that matters. A guard is required for any home where downspouts tie into underground drainage.

Frequently Asked Questions About Seamless Gutters in Jacksonville
What size gutters are best for homes in Jacksonville, FL?
For most Jacksonville homes, a 6-inch K-style seamless gutter is the right size. Larger custom homes, steep architectural rooflines, metal roofs, clay tile roofs, and high-volume roof valleys typically need 7-inch K-style. Very large homes, commercial buildings, and box-gutter applications can require 8-inch. Gutter Pro does not install 5-inch gutters in Northeast Florida because they overflow in Florida's high-volume rain events.
What gutter sizes and styles does Gutter Pro install?
6-inch, 7-inch, and 8-inch seamless gutters. K-style is available in all three sizes. Box gutter is available in 7-inch and 8-inch. Half-round is available in 6-inch and 8-inch. We fabricate seamless runs in commercial-grade 0.032 aluminum and 16 oz solid copper. We do not install 5-inch gutters.
Are seamless gutters better than sectional gutters?
Yes. Seamless gutters are custom-fabricated on site from a single piece of aluminum or copper to match your roofline exactly, which eliminates the joints in the middle of each run where sectional gutters typically leak. Fewer seams means fewer failure points, longer service life, and a cleaner appearance.
Do you use hidden hangers or spike-and-ferrule?
Gutter Pro installs heavy-duty hidden hangers spaced every 18 inches, screwed directly into the fascia board — tighter than the 24-inch maximum we allow on any install. Hidden hangers hold significantly more weight per foot than spike-and-ferrule and do not back out under thermal cycling. Spike-and-ferrule is 1950s technology that we will not specify.
What downspout size should pair with my gutters?
A 3-by-4-inch rectangular downspout pairs with 6-inch K-style on most Northeast Florida homes. A 4-by-5-inch oversized rectangular downspout is required for 7-inch and 8-inch gutters or any high-volume run. A 4-inch round downspout pairs with half-round gutters and copper systems. Undersized downspouts are the most common reason for overflow complaints.
What materials do you offer for seamless gutters?
Two materials for seamless runs: commercial-grade 0.032 gauge aluminum with a baked-on enamel finish, and 16 oz solid copper with soldered fittings for historic and architectural homes. Heavier 0.040 and 0.050 aluminum is available for fabricated box, custom, and commercial work.
Do gutters help protect my foundation?
Yes. Gutters collect roof runoff and move it away from the home before it can pool against the foundation. The combined system of properly sized seamless gutters, correctly placed downspouts, and underground drainage to a safe discharge point is what actually protects the foundation. Gutter Pro is NDS Certified for full water-system design.
Can you connect gutters to underground drainage?
Yes. Gutter Pro connects downspouts to underground drainage, catch basins, French drains, channel drains, dry wells, and pop-up emitters as part of a complete water-management system. All underground drainage is installed in FDM heavy-duty HDPE rated for vehicle traffic — or Schedule 40 PVC where the job specifically calls for it — never recycled black pipe, which collapses and silts up in Florida soil within a few seasons.
Do I need gutter guards with new seamless gutters?
Gutter guards are optional but strongly recommended for homes under heavy live oak or pine canopy, and required for any home where downspouts connect to underground drainage. LeafBlaster Pro 316 stainless micromesh is rated for both oak leaves and pine needles and carries a 40-year manufacturer warranty. Alu-Rex DoublePro adds a continuous hanger and double-layer aluminum guard that structurally reinforces the gutter — the coastal pick. Gutter Pro is an authorized installer for both.
How long does seamless gutter installation take?
Most residential seamless gutter installations are completed in a single day. Larger estate-scale homes, complex multi-story rooflines, or projects with underground drainage typically take two to four working days.
Do I need to be home during installation?
No. You do not need to be home during the install once the design and color are approved. The crew texts you at arrival, key milestones, and completion. Owner Albert is on site for the design walk and judgment calls.
Do you remove and haul away the old gutters?
Yes. Old gutters are removed, hauled away, and disposed of the same day as part of every install. We never leave debris in the driveway overnight. A magnetic sweep for screws and nails finishes every project.
What warranty do you offer on seamless gutter installation?
Lifetime workmanship warranty on every install. If a seam, corner, hanger, or downspout we installed fails, we fix it at no cost to the original homeowner. Manufacturer warranties cover the materials: 40 years on LeafBlaster Pro gutter guards, baked-on enamel finishes on aluminum, and solid copper components.
