Is your tankless water heater flashing an unknown error code? Do you dream of endless hot water and lower utility bills? 

We specialize in Navien tankless water heaters in Darien, IL and the surrounding areas. Because tankless systems do not store water and only heat it as it is being used, they are incredibly efficient. They also do not pose a risk of flooding like traditional tank style water heaters. They are about the size of a small suitcase and can be installed in the interior or exterior of the home and because of their compact size, they can free up space in your garage. Navien Tankless Water Heaters come with great warranties, and if the system does have an issue, individual components can be replaced instead of the entire unit like tank style water heaters. If you are considering upgrading your water heater, consider our tankless solutions. If you currently have a tankless water heater and it is time for annual service or it is flashing an error code, we can help. We provide fast and professional repairs to restore your hot water when you need it most.

If your home takes on water when snow melts or heavy rains arrive, a sump pump ideal. 

Water and sewage sump pumps are a necessity for many homeowners. They help move sewage to city systems and can help prevent flooding and mold growth in damp or low-level areas of your home.  Mold only needs a little bit of moisture and a food source, such as wood, paper, and glue, to grow and thrive. Toxic mold can cause health issues, such as respiratory failure. Once installed, sump pumps for both water and sewage operate automatically, but do require routine maintenance and service. Sump pump installation and repair is a specialty service and should be performed by trained and knowledgeable plumbers. We have more than 20 years of experience in sump pump services in Darien, IL and the surrounding areas. We will assess your needs and determine the best solution for your sump pump repairs, maintenance or new installation, walking you through the process from start to finish.

We own a multi-unit building that we also live in. This morning our tenant that lives below us informed me that she had water coming in from the ceiling, right below our bathroom. We called LaCassa and he came out right away (on a Saturday). Prior to his arrival, we got a call to confirm. The woman who called (I'm assuming she's his wife) was super pleasant and very personable. LaCassa arrived, figured out the issue quickly, explained the problem clearly, gave me our options, and completed the work quickly, all at a very reasonable price. He cleaned up and somehow managed to make our bathroom smell better after he was done than when he arrived. Highly recommend LaCassa and will definitely use in the future.

I recommend this company wholeheartedly! They are a pleasure to work with. From the ease of setting up an appointment, to scheduling me super fast, they know how to accommodate their customers! Not only that but Carmen was honest and fair about what needed to be done in my home. He was knowledgeable, kind, and worked efficiently. Most of all, he worked very cleanly and was able to solve my problem quickly! If you have plumbing issues, give them a call!

We tried LaCassa Plumbing after Carmen LaCassa replaced a water heater in our pastor's home.  We have had a leaky hose bibb on the front of our house for a couple of years and finally decided to do something about it when we heard about LaCassa.  Complicating the job was the fact that an electric conduit, water pipe and heating duct were all within a foot or so of each other in the crawlspace, leaving very little room to work, and the old bibb had been "mortared into" a front wall of uneven stonework. Carmen did a careful job of removing the old bibb with a minimum of disturbance to the stonework, and setting in and sealing the new bibb. I was under the impression that he was going to just bid-out our job, but was happily surprised when he was actually ready to do the repair on-the-spot. As a bonus, he is a very neat worker, using boot covers whenever he came into the house.

LaCassa Plumbing is of great service to its customers. Carmen is very knowledgeable and honest about the problems and solutions to the home. Not to mention, the prices are great for the quality of work done compared to other companies that want to charge an arm and a leg. This place is my new go to!
