Basement Drainage System Repair Cost

The cost to repair a basement drainage system varies depending on the severity of the damage, the type of drainage system and the size of the property. On average, you can expect to spend $846 on repair costs. By properly maintaining a drainage system, you can also save thousands on repair costs caused by water entering the basement.

Basement Drainage Repair Cost Factors

Basement Drainage Repair Cost Factors

One of the biggest factors that affects the cost of repair is the extent of the damage. Professionals can often remove simple clogs in a short amount of time, meaning there's a lower cost. However, if there are multiple clogs, the contractor needs specialized equipment or excavation tools to repair the damage. As such, you can anticipate a much higher cost. The season or time of year also affects the cost. Plumbers tend to offer lower rates during their slow seasons and higher rates during busy seasons — such as seasons that see a lot of rainfall and flooding — due to demand. Regular maintenance of any type of drainage system reduces the chances of damage and saves you from unexpected repair bills.

Cost To Install New Drainage

If your current drainage system is nonexistent or damaged beyond repair, then it may be necessary to install a brand new drainage system. In some instances, this might be the less expensive option. For example, installing a floor drain costs between $100 and $500 on average. The cost for installing a sump pump in a typical home costs between $2,000 and $6,000, but can be as much as $10,000 to $15,000. Exterior French drains cost an average of $750 to $1,250. Interior French drains are often installed as a last resort and are significantly more expensive than their exterior counterparts. Costs for installing this new French drain range from $2,000 to $15,000.

Significance Of Basement Drainage

Without a functioning drainage system in the basement, homes are prone to flooding and water damage. A basement drainage system functions to keep water out of the house and to move it away from the home when it appears. Moisture that's allowed to build up in a home can cause a number of problems, including structural damage. A concrete foundation can crumble and crack when exposed to water for a long period of time. Likewise, moisture can lead to mold and mildew growth in the basement, which can cause health problems. Thus, it's important to call a plumber or contractor to make repairs before a small problem turns into a large one.

Best Basement Drainage Systems

The three most common types of basement drainage systems are floor drains, sump pumps and French drains. Floor drains are perhaps the most popular because of their cost effectiveness and the fact that you can retrofit them into existing structures. Floor drains are installed just below the basement floor and prevent water from leaking into the basement.

Sump pumps function to keep water out of the basement and to automatically drain any water that does happen to get into the space. These are common in homes that are prone to flooding or in homes where the water table is located above the foundation. Sump pumps are installed in a pit; water flows naturally into the pit and the pump removes it.

French drains can be installed inside or outside the basement. These drains are perforated pipes that route water away from the foundation or basement. The pipes connect to a gravel-lined trench that's angled away from the home.

Significance Of Basement Drainage

Common Repairs

No matter which type of drainage system you choose, there are common repairs and maintenance tasks you should keep in mind. Sump pump and floor drains are prone to backing up. This is especially common during times of flooding or periods of heavy rain when the system becomes overwhelmed with water. Because French drains tend to be open, gravel, dirt and other debris can enter the system and cause a clog. Drain fabric helps to reduce this problem, but you'll need to have the fabric professionally cleaned in order to keep the system draining properly.

DIY Or Hire A Pro?

When dealing with an issue as important as basement drainage, it's best to hire a professional. It's possible to install or repair a drainage system as a DIY project, but a professional knows how to identify the causes of leakage and water backing up into your basement. Additionally, it's important to contact utility companies before excavating. Neglecting to do this could result in damaging utility lines and lead to higher repair costs.

How To Avoid Basement Flooding

In addition to installing and maintaining a proper drainage system, there are a number of things you can do to prevent basement flooding. Keeping gutters and drain spouts free from debris and pointed away from the foundation helps move water away from the home during a rainstorm. Sealing up cracks in the foundation prevents water from leaking into the basement. Lastly, having the sewer or septic system cleaned and inspected regularly helps prevent a disaster from occurring after periods of heavy rain.
