A bittersweet lunch today in honor of one of our most loyal employees, Jeff Frerich! He has been at Casa for 19 years and his hard work and dedication will be greatly missed by his builders, crews and fellow employees. Thank you Jeff for all that you have done here at Casa and best of luck to your future in Houston!


Needing a new water heater? Maybe it’s time to move on from your traditional water heater and make the switch to tankless. A tankless heater is not only more efficient, it will also save you money on your water bill. A few more reasons why tankless might be the better option:

✅hot water on demand- no water is sitting in a storage tank to wait on
✅no odors and sediments- no tank causing sediment build up (which then comes out in your water)
✅no flooding- no tank means no cracks causing water leaks

Call us today to talk with someone about a new tankless install!
