Gutters and Drainage in Florida
Engineered for Maximum Foundation Protection
Foundation Waterproofing 101 LLC specializes in gutters and drainage in Florida—not guesswork. As the state’s only true water hydraulics engineering firm and a Certified General Contractor (License #CGC1539326), we design systems that control water flow, prevent hydrostatic pressure, and permanently protect your foundation.
We brought real waterproofing science to Florida in 2016. Since then, others have tried to copy what we do—but they still get it wrong. This page explains how properly engineered Florida gutters and drainage systems should be built to last.
Why Gutters Matter for Foundation Protection
When rainwater falls off your roof with no control, it saturates the soil around your foundation. Over time, that creates hydrostatic pressure, soil erosion, and allows a water table to form around the structure.
Here’s the funny part: why is it that Florida builders never install gutters? What’s the problem? The rest of the country uses them—Florida needs them the most. Homeowners see it every day and know it makes no sense.
Once a localized water table develops around a home, it’s permanent—you can’t remove it. That’s where hydrostatic pressure comes into play. While the water table can’t be erased, we control it with engineered hydraulic systems that manage flow, pressure, and discharge.
Typical cost of gutters in Florida: $10–$15 per linear foot installed (roof height, profile, and complexity may affect price).
6-Inch Seamless Aluminum Gutters for Florida Homes
Our 6-inch seamless aluminum gutters are designed for Florida’s intense rainfall and large roof areas. They handle up to ~40% more flow than standard 5-inch systems, eliminating overflow and keeping water away from foundations.
- Seamless, leak-free design formed on-site
- Heavy-gauge aluminum for coastal durability
- Multiple colors and profiles
- Built to outlast Florida’s humidity and storms
Hydraulic Discharge Design for Gutters and Drainage in Florida
Here’s where most contractors fail. Downspouts are pressure lines; French drains are gravity systems; sump lines are mechanical. Mixing them violates basic hydraulics and guarantees failure in heavy rain.
What Not to Do
- Never connect downspouts to French drains.
- Never tie downspouts into sump discharge lines.
- Never use perforated pipe for roof runoff.
What To Do Instead
- From each downspout, run a solid 4-inch PVC discharge line a minimum of 20 feet from the structure to a grate box, splash basin, or approved discharge area.
- If the discharge point is higher than foundation grade, extend the solid pipe ~18 inches vertically near the downspout to create a hydraulic column. That column builds head pressure and keeps flow consistent.
Typical installed price for solid 4-inch PVC discharge: ~$25 per linear foot (depth, routing, and obstacles can affect cost).
This is the hydraulic standard that makes our gutters and drainage systems in Florida outperform every competitor.
Florida Building Code & Elevation Requirements
Florida doesn’t have a dedicated “waterproofing code.” It relies on elevation and drainage provisions in the building code to reduce stormwater and groundwater intrusion. See the Florida Building Commission and the ICC-hosted Florida Building Code for current language.
The first-floor slab must be at least 12 inches above finished grade (Florida Building Code – Residential, Foundations).
We don’t just follow code; we design above it because every site in Florida is different—soil type, slope, elevation, and coastal/tidal influence vary on every property. It takes a specialized trade with years of field experience in water hydraulics to interpret those factors and engineer systems that actually work.

Complete Florida Foundation Waterproofing & Drainage Systems
We don’t offer patchwork fixes—we engineer full-system protection from roof to soil, integrating gutters and drainage in Florida that control water at every level.
- Seamless Gutters & Downspouts
- Solid PVC Discharge Lines (minimum 20 ft from structure)
- Foundation Waterproofing & Sealants
- Grading & Surface Drainage Correction
- Crawlspace & Basement Waterproofing
- Sump Pumps (only when mechanical lift is required)
Our perimeter systems—what we call the Foundation Waterproofing & Hurricane-Resistant System—are built to meet or exceed performance expectations used in the International Building Code for northern states. Florida lacks explicit waterproofing standards; we deliver the protection those codes expect.
