Crawl Space Sump Pump Installation
Give standing water a way out. We install Workhorse sump pumps with a drainage plan that collects crawl space water and carries it away from your home.
Drainage gives collected water a route to the sump basin.
How Does a Crawl Space Sump Pump Work?
A sump pump sits inside a basin that collects water from the crawl space drainage system. As water rises, a float switch activates the pump, sending that water outside through a discharge line.
The pump is one part of the solution. We inspect how water enters, how it reaches the basin, and where it will discharge. Crawl Space Brothers provides sump pump installation, repair, and replacement.
Different moisture problems. Connected solutions.
Water on the ground, moisture in the soil, and humidity in the air need different approaches. Your inspection shows which parts your home needs.
Cover the ground.
A sealed vapor barrier helps limit moisture evaporating from exposed soil into the crawl space.

A dehumidifier removes moisture from the air after water entry and ground moisture are addressed.

Does Your Crawl Space Need a Sump Pump?
Recurring water is the starting point for an inspection. The right repair depends on its source and the way it moves through your crawl space.
- Water after heavy rain
- Puddles or a wet crawl space floor
- An existing pump that needs attention
Standing water or repeated flooding
Water that collects after rain can indicate groundwater entry or a drainage issue. A sump pump may be recommended when collected water needs to be actively discharged.
Water collecting in low areas
The lowest area often shows where water is gathering, but the whole drainage route matters. We inspect the crawl space layout before recommending basin placement.
Leaking pipes or water directed toward the house
A plumbing leak, downspout outlet, or grading issue may be contributing to the problem. Those sources need attention; adding a pump should not leave the cause unexplained.
A pump that stops, cycles unusually, or leaves water behind
Unusual noise, frequent cycling, or rising basin water can mean the system needs service. The pump, float, drainage route, and discharge line should be assessed together.
A complete route from water entry to discharge.
We install Workhorse sump pumps as part of a system planned for the water conditions beneath your home.
Collect the water
A drainage route carries water toward a sump basin positioned for the crawl space layout.
How drainage and the basin connect
Drainage helps collect water across the affected area. Where the layout allows, it flows by gravity into a basin installed at an appropriate low point. We explain any additional drainage or source repairs in the plan.
Install the sump pump
The pump sits inside the basin and activates as water reaches the float switch.
What the pump does
The pump lifts collected water into the discharge line. Basin access, float movement, and the installation environment matter to operation. We check the installed system rather than treating the pump alone as the whole solution.
Route and check the discharge
We plan where the water exits, check operation, and explain access and maintenance.
Why the outlet matters
The discharge route needs to carry water away without sending it back toward the crawl space. We assess the site and outlet conditions and review the completed system with you.
Already have a sump pump?
A working pump depends on the system around it. Repair or replacement starts with understanding what has changed.
Explore TotalCare™ MaintenanceWater remains even when the pump runs
Water may not be reaching the basin, the pump may not be keeping up, or the discharge path may need attention. An inspection can identify which part of the system needs work.
The pump is noisy or behaves differently
Changes in sound, cycling, or water level are useful details to share when scheduling service. We assess whether repair, adjustment, or replacement is appropriate.
Plan for maintenance and power interruptions
Routine checks help identify obstructions and equipment problems. A standard electric pump relies on power; discuss outage concerns during your inspection so any additional protection can be evaluated for your home.

I had called Crawl Space Brothers in Nashville, TN to come analyze a long overdue issue in my crawl space. Have lived in my home over 20 years..and the "original " part was from the 1950's..animals, shoddy plumbing, and lots of moisture/water had left my crawl space in a horrible condition! ( as a person can imagine!). Mike Goodman was the analyst that came out. He spent a full hour thoroughly examining every square inch, documenting his findings, took accurate readings of both moisture and humidity levels at the current time. Upon reaching back on ground..he went over a vast portfolio of pictures. My jaw dropped at what I saw. Mike Goodman went over how Crawl Space Brothers can tackle every problem with ease and professionalism at every part of the process. My crawl space requires a sump pump & dehumidifier..plus all the good as gold encapsulation. Prior to this job being started..I have called Mike to ask further questions..he is very easy to reach..a big plus! He also came to repair an existing plumbing issue....before their job is started. That was above and beyond...very appreciative for his speedy help in that matter. This company is Top Notch. Excellent Professionalism. And for a company to ease my mind..they have done just that!! Really excited for my new clean legit crawlspace...and it's all updated to today's modern standards. Big Thanks To Mike Goodman with Crawl Space Brothers 🙌. It's definitely is worth your time to take a look at your crawlspace! Best regards, Claire (West Meade) Nashville, TN

Crawl Space Brothers replaced the vapor barrier beneath my house recently. I appreciate that they didn’t try to “upsell” me on more expensive solutions or unnecessary equipment (I.e. sump pump) like other companies did. They were fair and honest. The work was done by a crew of friendly, efficient and professional people. All trash and debris removed. They also put insulation back where it had come down in a couple places. Very pleased with the results. Thumbs up!

Every crew in every aspect of the process was phenomenal. The work done was top notch and I truly appreciate the efforts. They have a superb team of wood workers that came in to replace some rotten structural and they crushed it. Sorry guys, I cannot remember all of your names. Hats off to you three! The encapsulation techs Leonard and Scott attacked the crawl and ended with a super clean installation of material as well as sump lines and a dehumidifier. I'm in crawlspaces for my job as well, so I've thoroughly examined the work and am very pleased. David in sales, thank you sir. I appreciate all of your efforts and will recommend you to those in need! Much love to you gents.

I'm pretty happy with the work and price. Both the sales rep and installers showed me pictures throughout, and kept me up to date with the progress. The electricians they use are outsourced, which may have been the cause of a little confusion for my installation job. Our sales rep, David, was great. He was laid back and didn't push unnecessary solutions. In fact, I even ended up calling him back after a particularly bad storm so I could add more drainage and sump pumps to my quote. There was an unexpected change in scheduling, so my crawl space was started and finished a week earlier than scheduled. That was an improvement for me, since I work from home with a flexible schedule. The only downside is that I didn't hear from the electrician until I called the CSB office two weeks later (assuming the scheduling conflict was the initial issue). Our installers, Devon and Daquan, were excellent. They were very professional and kept me informed as they progressed. Devon even warned me that there may be some confusion on the electrical side due to the change order. That warning came true and was able to be resolved the same day, so shout out to Devon for seeing problems before they happen. The electrician, Cody, was great as well. There was a small mix-up with the number of outlets needed, which he resolved immediately. It has only been a few weeks since the installation, so I'll update this post if I run into any issues.

Crawl Space Sump Pump Installation FAQs
Do all crawl spaces need a sump pump?
No. The recommendation depends on water conditions and the drainage plan. A crawl space with a humidity problem may need a different solution from one with recurring groundwater or standing water.
Can you install a sump pump in a dirt crawl space?
Yes, when the conditions support that repair. The inspection establishes where to place the basin, how to collect water, and how to route the discharge.
What sump pumps does Crawl Space Brothers use?
We install Pro Series sump pumps for the standard crawl space sump-pump system. Your written plan explains the equipment and drainage work recommended for your home.
How long does a sump pump last?
Service life varies with operating conditions, how often it runs, and maintenance. We assess the condition of an existing system rather than promising one lifespan for every installation.
What if my crawl space sump pump is not working?
Arrange a service assessment and describe any noise, cycling changes, or standing water you have noticed. Avoid entering flooded areas around electrical equipment. The inspection can determine whether the pump, float, or drainage and discharge routes need attention.
Will a sump pump affect my home’s value?
A documented water-management repair can help explain how a moisture problem was addressed. Its effect on a sale depends on the home and local market; we do not promise a resale increase.
