French Drain Cost Per Foot
1. Interior French
An interior French drain refers to a trench for channeling water into a sump pump pathway. The trench has a perforated pipe in it, which is also filled with gravel. The trench floor is level, and holes in the pipe are designed to allow water to flow through it. From there, the pipe and water flow run under the ground and away from the house to a safe site. In San Francisco, this system has a standard price of $40 to $100.
2. Exterior French Drain
The primary role of an exterior French drain is to move water away from your basement. This prevents seepage into the walls, consequently reducing the risks of mold and moisture damage. The price of an exterior French drain ranges from $10 to $75 per linear foot.
3. Curtain drain
A curtain drain, also known as an interceptor drain, is an external drainage mechanism. Unlike more comprehensive drainage options, a curtain drain isn’t designed to protect a structure. Instead, it safeguards an area (like a lawn) from becoming waterlogged. These drains are used when shallow depth is needed and heavy water flow is absent. A good ballpark for this installation is between $10 and $20 per linear foot, depending on the installation quality and materials used.
4. Trench or yard drain
Yard trench drains are frequently implemented to help control surface water running over impervious hardscapes like driveways or patios. This drain is designed as an elongated, narrow cavity, which is instrumental in diverting water from garage entrances and around the yard. The cost per linear foot is $5 to $15.

Frequently Asked Questions:
1. Who can benefit from a French drain in San Francisco?
San Franciscans facing problems with drainage, exemplified by standing water, flooding or soil erosion, can significantly benefit from French drains. Due to their effectiveness, they are the top choice for houses with sloping backyards, low-lying areas, or areas with high water tables or heavy rainfall. Fundamentally, they will be indispensable to homeowners who wish to prevent their basements and crawl spaces from getting water damaged since this can lead to structural problems and excessive mold growth. The French Drainage systems can help remove excess moisture from the edges of homes, providing permanent safety and peace of mind for San Francisco residents.
2. What are the benefits of French drains in San Francisco, CA?
Through the installation of French drains, San Francisco homeowners can have an opportunity to enjoy several benefits. French drains divert excessive water from the foundations, basements, and crawl spaces, defying the likelihood of interior damage. What was once considered a solution used only in regions with heavy rainfall is now used to prevent downslope seepage, which typically creates wet basements, crawlspaces, and foundation-related moisture problems.
3. Are interior French drains effective?
French drains inside the house have proven themselves as instruments to prevent excessive moisture. Moisture in basements or crawl spaces leads to molds, warping, and decay of wood materials. The accumulation of these problems causes extensive damage and costly renovations. Indoor French drains are particularly useful in areas with high groundwater tables or buildings lacking proper exterior drainage facilities. When correctly installed and maintained, these systems can last a lifetime. Installation and regular maintenance are crucial; however, it is also strongly recommended that they be used in conjunction with outdoor French drainage.
4. How long do French drains last?
The lifetime of a French drain is variable; however, with proper installation and care, it can endure for many decades. A well-placed and suitably structured French drain’s average longevity ranges between twenty and thirty years. The lifespan of this drain depends on the material used, the local soil, and the amount of water it carries. Nonetheless, measures should be in place, like regular maintenance that goes hand-in-hand with an excellent working attitude and proper cleaning, to ensure longevity. As time goes by, the pipe and gravel might expire, while the hole will forever give your property a facelift with just a little upkeep and repairs on the side.
