Cost to Repair Basement Drainage Systems

Various factors affect the price of repairs to a basement drainage system. Plumber costs will vary from as little as $45 per hour to snake a line to $150 per hour or more for complex issues during busy seasons. The price will vary depending on the extent of the damage, the original condition of the system, the season when the work needs to be done, availability of professionals and more.

the average cost to repair basement drainage is $2,100 or $100 to $9,400

In addition to clogs within the pipes, systems that feed into the sewer can begin to back up if the sewer itself backs up, which can occur at times of heavy rain. Having more than one system in place can help make up for weaknesses within each system and can ensure that even if one system fails, another one is available to help. The cost to install a second drainage system depends on what is being installed, but can range from $1,000 to $3,000 on average. For more information, see the Installation section below.

Annual maintenance checks can help prevent system failure. Camera inspections of sewers and drain lines can run you between $100 and $800, depending on the method of inspection, length of the pipe and other factors.

French Drain and Drain Tiles

Homeowners who need to have their French drain cleared through hydrojetting services should plan to pay a plumber between $150 and $200 per hour for the clog to be cleared. If the clog occurs because of a collapsed drain line and it needs replacement, your total budget can grow to be substantial. The average cost to install an internal line is $50-$60 per linear foot, which can add up very quickly.

A French drain is a perforated pipe in a trench, surrounded by tile. Water in the ground filters into the trench and fills the pipe, and then the pipe carries the water away. Usually, they empty at an outlet on the outer edges of the property and rely on hydrostatic pressure in the soil to work. A shallow one drains less water because the pressure is reduced. A deep-channel system is buried deeper in the ground, where there is greater water pressure. Deep-channels relieve more pressure from the foundation.

The cost to fix a clog depends on the type of problem the drain is experiencing. Small clogs can occur because of tree roots and debris. Older systems may suffer from pipe collapse. If the system is in good condition, hydrojetting is a relatively fast and inexpensive way to clear the clog. If the pipe is collapsed or in poor condition, replacement is likely the only solution.

Floor Drains

These are often cleared by plumbers who use an electric snake in the line. The rate a plumber charges to service one may be as little as $100 to $300, depending on the cause of the clog, the severity of the issue, and other factors.

A floor drain is a pipe in the middle of the basement floor. This pipe leads to the home's sanitary line, where it eventually feeds into the sewer. Basement floors often have a slight grade so they will funnel very gradually to the drain which usually has a screen over it. These, too, can develop clogs. Sometimes these clogs are caused by corrosion in the pipe. Some may be caused by objects that work their way into the pipe.

Sump Pump

Most homeowners spend between $250 and $700 to repair their sump pump. Sump pumps are designed to turn on when the water level in the sump reaches a certain height. The pump removes the water from the sump and drains it into the yard. Some common causes of problems include pressure switch failure and tank damage. A pressure switch can cost about $40 to replace, in addition to the service charge. A full tank replacement can run you anywhere from $250 to $500, plus the price of installation.

The best way to avoid problems is to get the technician out to the house as soon there are issues. Warning signs of issues include:

  • Loss of pressure.
  • It makes strange noises.
  • Flooding.

Homeowners are advised to contact a repair person in their area if their sump pump displays problems.

Average Cost of Installing Basement Drains

Basement drain systems come in different types, so installation costs vary between $1,000 and $5,000.

  • French drain: $1,000-$5,000. They can be very effective, but need to be maintained by a qualified contractor or plumber to avoid clogs. Deep-channel French drains can help control moderate to heavy moisture, while shallow channel ones are better or light to moderate moisture.

  • Floor drain: $3,200. The price for this type of installation will depend on the length of the line, the amount of digging to be done in the basement and other factors. They can help control moisture but are best for catching overflow from nearby sinks and appliances.

  • Sump pump: $1,100. Sump pumps cost an average of $1,100 to install. They’re best used in conjunction with another type of system, like a French or floor. They can help homeowners with light to moderate moisture in their basement.

For homeowners, deciding which system is needed can be a challenge. The best way to address this problem is to work with a reputable, licensed professional. For more information about installation, take a look at our drainage installation page.

Basement Flooding and Water Damage Restoration Costs

Flooding and water damage due to damaged or clogged drain systems can be expensive. The average cost of fixing water damage in a home is about $2,500. Water damage can lead to mold growth, structural damage and health problems for members of the household.

Installing a full basement waterproofing system is the best way to avoid costly and inconvenient damage. In addition to the interior waterproofing solution described, many homeowners must turn to other controls to keep water at bay. Some of the most common tools that homeowners use to control moisture include:

  • Gutters help lead water away from the foundation. A lengthy downspout can be used to direct water to a place far away in the yard.
  • Landscape solutions. Dry rivers, drainage ditches and proper landscaping techniques can help keep moisture out of the basement. Sometimes just installing the right kind of water-loving tree can help control moisture in the soil around the house, while angling soil away from the house can prevent water from pooling around the foundation.
  • Dehumidifiers can help reduce humidity, thus reducing the chances of mold growth. Dehumidifiers can also prevent the moisture from drying up.
  • Sealing your walls can help keep moisture on the other side of the basement, and can also help prevent water from seeping through hairline cracks in the walls.

Basements that experience light flooding throughout the year are vulnerable to more severe flooding when serious rain storms hit. Homeowners who do not take the time to protect their home and their belongings could be at risk.

Most homeowners use a combination of waterproofing and moisture control options to prevent flooding. The best way to do this is to hire a licensed professional who can identify the cause of the problem. Once the issue is diagnosed, then solutions that address the true problem can be selected. When working with a contractor, be sure to pick someone who is licensed and insured. Learn more about hiring a licensed professional.
