Jensen Sprinkler

Jensen Sprinkler installs quality, water efficient irrigation systems. 

We also provide continued service and customer education after our initial installation. 

We have knowledgeable, experienced field technicians to keep your system in top running form.


​Underground Irrigation

​    Jensen Sprinkler specializes in underground irrigation, or sprinklers, hence the name. It is what we do. It is our main industry focus. We don’t have a multifaceted business including plumbing, landscaping, mowing, tree trimming or Christmas lights like many other companies. We know that they can offer “package deals” that may seem more convenient and cost effective on the surface, BUT think about this – Can one company be really good at a dozen different things? Would you go to a podiatrist if you were having a heart attack or hire your lawn guy to cut your hair? The skill sets are similar, but they aren’t just focused in on what you really need. With most package deals, you aren’t getting the best sprinkler possible for your investment. 

     At Jensen Sprinkler we have a combined industry experience of over 80 years. We are committed to continuing education for our key employees.          

            We don’t have a plan B for our livelihood, so providing you with the best possible irrigation system is our key focus.  In other words, YOU are our plan A.

            We have designed and installed sprinkler systems of all sizes and styles. You would be hard pressed to travel anywhere in Sioux City and not pass several of our installations. Although we often showcase our commercial projects (frankly because it is awkward to take photos of someone's home!), about 95% of our installations are residential. It speaks volumes about our business that our greatest advertising come from our own customers! We often will end up doing several homes on the same block or do installations for various members of the same family. We have been around long enough now that we have done installations for the grown-up kids of some of our long-time customers. 

    Our sprinklers are installed with quality, contractor-grade products by Rain Bird©. We offer a one-year warranty on parts and installation. After your sprinkler installation we will teach you the process of winterizing and starting your new system. If that isn't something you are interested in doing yourself, we have experienced service technicians to handle those processes for you moving forward. 

    There is a Jensen Sprinkler difference.

​LED Landscape Lighting

​    Landscape lighting is an often overlooked component in the overall curb appeal of your home. We want the grass to be green and the plants to be healthy, but what kind of appeal does your house offer after the sun goes down or in the dead of winter? Lighting can enhance the look and security of your home. There are lighting choices to meet almost any budget and the possibilities are endless. Many homeowners start out with minimal lighting around the front of their home and love it so much they expand to other areas in their yard as their budget allows. There are lighting fixtures to match and enhance any style of decor, finish, personal preference or whimsy.

​What are the benefits of landscape lighting? 

    LED lights are long lasting and highly effective. LED lights utilize 80% less voltage than halogen based lights, reducing and lower energy costs.  If you travel, landscape lighting can increase the security of your home. Lighting timers and a well lit exterior will give the impression of occupancy even in your absence. Well placed exterior lighting offer such a security bonus that many insurance companies will offer reduced homeowner’s insurance premiums if you invest in landscape lighting.


​Underground Drainage Systems

​Underground drainage systems are simply a combination of buried pipes that move the water from your existing downspout(s) out to daylight in your yard – away from your home. Draining rainwater underground reduces surface run-off, eliminates unsightly downspout extenders and reduces the chance of excessive rainwater ending up in your basement.

What does drainage have to do with sprinklers? We get called out at least a couple times a season to assess reasons why a homeowner is getting water in his/her basement. Why call your sprinkler guy? Because people with irrigation systems assume that the problem lies in the sprinkler because it has live water lines outside. More often than not that is not the case, but we have garnered a whole lot of knowledge over the years checking into it for people. The most common reason people get water in the basement is due to clogged gutters. Truly. During hard rains a clogged gutter will overflow and dump all that water right next to the foundation. The lesson here? Keep your gutters clean! The second thing we see is trapped downspout drains. With the boom in the popularity of concrete curbing and landscape edging, we have seen more people with water issues. Why? Often the above ground downspout disperses rainwater inside a concrete edged plant bed. In big rains the water backs up behind the concrete curbing, down the foundation walls and into your basement. There are also grade issues, foundation cracks and myriad of other reasons you may be getting water in your house that our outside of our realm of correction and if it is, we can’t point you in the right direction.


We are not taking on new service properties at this time. If you are unhappy with your current provider and searching for a new service company, we can't be that provider for you.  Please accept our sincere apologies in this. We wish we could take care of everyone! In 2020 we made the extremely difficult decision to cease accepting for service sprinklers that were installed by other companies. This decision was made to honor our long-term customers as well as those who choose us for their installations in the future. We want to continue to provide the best service possible.

However, if you have moved into a new home and that home has a Jensen Sprinkler system installed, or we have been servicing your new property for the previous owners, we will continue to service that property. If you aren't sure, fill out the form linked to the button below and we will check our records. 

Of course, if you are an existing Jensen Sprinkler customer and you change your residence, we will continue to take care of you in your new home!!
