Professional Gutter Installation in St. Louis, MO
Seamless gutter installation, replacement, and repair for St. Louis homeowners. Custom-fabricated on-site. Backed by a workmanship guarantee from a locally owned contractor.
Why Gutters Matter More Than You Think
A properly functioning gutter system is your home’s first line of defense against water damage. Without it, rainwater erodes soil around your foundation, floods basements, stains siding, and accelerates rot on fascia boards. For St. Louis homeowners dealing with 40+ inches of annual rainfall — plus spring storms that can dump several inches in a single day — reliable gutters are not optional.
Foundation Protection
Directs water away from your foundation to prevent cracking, settling, and costly structural repairs that can run $5,000–$15,000+.
Prevents Basement Flooding
Channels roof runoff into downspouts and away from your home — the single most effective defense against a wet basement in St. Louis.
Stops Landscape Erosion
Without gutters, water cascading off your roof carves trenches through flower beds and mulch. Seamless gutters control the flow and protect your landscaping investment.
Ice Dam Defense
Properly sized gutters with adequate slope help prevent ice dams during St. Louis winters, reducing the risk of water backing up under your shingles.

Gutter Replacement
If your existing gutters are sagging, rusted, or pulling away from the fascia, a full replacement is often more cost-effective than patching. We remove the old system, inspect the fascia for rot, and install a new seamless gutter system designed for your home.

Leaking joints, loose hangers, damaged sections, or clogged downspouts — we diagnose the root cause and make lasting repairs. We also install additional downspouts when your current system can’t handle the volume (a common issue on homes over 2,000 sq ft).

Gutters don’t last forever. If you’re seeing any of these signs, it’s time to call a professional before the damage spreads.
Sagging or Pulling Away
Gutters pulling away from the fascia board usually mean the hangers have failed or the fascia is rotting behind the gutter. Either way, patching won’t fix it.
Water Pooling at the Foundation
Standing water within 2–3 feet of your foundation after rain means your gutters aren’t directing water properly — or they’re overflowing.
Visible Rust, Cracks, or Holes
Rust spots and cracks on older galvanized gutters allow water to drip behind the system, causing fascia and soffit damage you may not notice until it’s severe.
Overflowing During Rain
If water pours over the edges during moderate rain, your gutters are either undersized, clogged, or improperly pitched. St. Louis thunderstorms will expose a weak system fast.
Mold or Mildew on Exterior Walls
Dark streaks or mold growth on your siding directly below the roofline is a telltale sign of persistent gutter overflow or leaks.
Peeling Paint or Staining
Water running behind or overflowing from gutters strips paint and stains the fascia, soffit, and exterior walls. If you’re repainting the same areas repeatedly, the gutters are the real problem.

Gutter Installation FAQ
How much does gutter installation cost in St. Louis?
Gutter installation costs vary based on the size of your home, material, number of downspouts, and whether fascia repairs are needed. Most residential projects in the St. Louis area fall within a predictable range. We provide free on-site estimates so you get an accurate number — not a ballpark from a website.
How long does gutter installation take?
Most residential gutter installations are completed in a single day. Larger homes or projects that require significant fascia repair may take two days. We’ll give you an estimated timeline when we provide your quote.
What’s the difference between seamless and sectional gutters?
Sectional gutters come in pre-cut pieces that are joined together on-site, creating seams every 10 feet. Those seams are the #1 failure point — they leak, collect debris, and separate over time. Seamless gutters are formed from a continuous piece of aluminum, which means fewer leaks and far less maintenance. We install seamless gutters exclusively because they last longer and perform better.
Do you repair existing gutters or only install new ones?
Both. We handle gutter repairs including reattaching loose sections, replacing damaged runs, fixing leaking joints, and adding or relocating downspouts. If a full replacement makes more sense financially, we’ll tell you that upfront.
Should I get 5-inch or 6-inch gutters?
Standard 5” gutters work for most homes. We recommend 6” gutters for homes with steep roof pitches, large roof areas, or areas that collect heavy runoff — all common situations in St. Louis. During our inspection, we’ll measure your roof and recommend the right size based on actual drainage calculations, not guesswork.
Can gutters be installed during winter in St. Louis?
Yes. Aluminum gutters can be installed year-round. Cold weather doesn’t affect the material or sealant performance. In fact, replacing failing gutters before winter helps prevent ice dam damage during freeze-thaw cycles, which are common in the St. Louis metro from December through February.
Seamless Gutters vs. Sectional Gutters
An honest comparison from a contractor who has installed both.
| Category | Seamless Aluminum | Sectional (Big Box Store) |
|---|---|---|
| Leak Risk | Minimal — no joints except corners | High — seams every 10 ft leak over time |
| Durability | 20–30+ years with proper hangers | 10–15 years typical before sagging |
| Custom Fit | Fabricated on-site to exact measurements | Pre-cut lengths, spliced to fit |
| Maintenance | Low — smooth interior, less debris buildup | Higher — seams trap leaves and debris |
| Appearance | Clean, continuous lines — 25+ color options | Visible seams every 10 ft |
| Installation | Professional crew, typically same-day | DIY-possible but error-prone |
| Warranty | Workmanship guarantee + material warranty | Material only, no labor coverage |
| Best For | Homeowners who want a lasting, low-maintenance system | Temporary fixes or rental properties |
Bottom line: Sectional gutters from a hardware store cost less upfront, but seamless gutters installed by a professional outperform them in every metric that matters over time. We install seamless gutters exclusively because they’re the better long-term investment for St. Louis homeowners.
What St. Louis Homeowners Say
Real feedback from homeowners across the St. Louis metro area.
We had Meridian replace all the gutters on our house after the old ones started pulling away from the fascia. The crew showed up on time, fabricated everything on-site, and finished the whole job in about five hours. No mess left behind and the new gutters look great. Would absolutely use them again.
Had gutters and downspouts installed on a new addition. Alex came out personally to measure and recommended 6-inch gutters because of our steep roof pitch. Smart call — we haven’t had any overflow issues even during heavy storms. The seamless look is a big upgrade too.
We hired Meridian for a full roof replacement and added new seamless gutters at the same time. Having one contractor handle both saved us money and the coordination was seamless. Honest pricing and solid work from start to finish.
