What is a French drain and how does it work?

A French drain is a gravel-filled trench containing a perforated pipe that collects and redirects surface and groundwater away from your foundation. Water enters through the perforations, flows through the pipe, and discharges at a safe location away from your home.

How much do exterior drainage solutions cost in Atlanta?

French drains typically cost $2,500-$8,000 depending on length and depth. Downspout extensions range from $200-$800 per downspout. Grading and swale projects vary from $1,000-$5,000 based on yard size and soil conditions. Hydroguard provides free estimates.

How far should downspouts extend from my house?

Downspouts should discharge at least 10 feet away from your foundation. In Atlanta's clay soil, which drains poorly, extending them 15-20 feet is ideal to prevent water from seeping back toward your foundation.

Will a French drain solve my basement flooding problem?

French drains are highly effective for surface water and high water tables. However, if water is entering through foundation cracks or below-grade seepage, you may also need interior drainage or foundation waterproofing. We assess your specific situation and recommend the best combination of solutions.

How long do French drains last?

Properly installed French drains last 20-30+ years. The key is using quality materials (geotextile fabric to prevent clogging, proper pipe grade, adequate gravel) and correct installation. Our systems are built to last.

Can I install drainage solutions myself?

While possible, professional installation ensures proper slope calculation, correct depth for freeze protection, appropriate discharge locations, and compliance with local codes. Improper installation can worsen drainage problems or violate regulations.

Do I need permits for exterior drainage work?

In most Atlanta-area jurisdictions, French drains and grading typically don't require permits. However, if work affects storm water management, property lines, or public right-of-way, permits may be needed. Hydroguard handles all necessary permitting.

What is the best way to prevent foundation water damage?

The best protection is a layered approach: proper grading directing water away, functioning gutters with extensions, French drains where needed, and interior drainage as a backup. This comprehensive system handles all water sources.
