I called and left a voicemail at Tri-County Pump. Brandon called me back within 20 minutes. He did a FaceTime session with me, so he could see my setup. He determined that my booster pump (from the early 80's) was bad. He showed up this morning, Christmas morning, before 7:00AM!! My pump was so old that he had to replace all of the plumbing. He gave up nearly two hours of his Christmas, all while fighting the wind and rain!! Thank you so much, Brandon, for saving our Christmas!! It was a Christmas miracle!!!

On Monday he called and asked if they could come early. When does that ever happen?! They met me at my property and diagnosed the problem. We were having major issues with our pressure. Our pump was also 19 years old. Our well desperately needed a glow up. That night he sent me an itemized quote with work we agreed on as well as possible other expenses. That way we wouldn't be surprised at the end. Transparency is always appreciated. Our neighbors were super impressed with the efficiency of the team.

He proudly stated that the spot that was drilled was selected because it was the easiest place to get his drill rig into!!! He never bothered to witch the property or even look around for the best water area! He did Not have it "witched" to determine best drilling location! As a result, he drilled over 700 feet a got very little water. Well went dry five years later!!! If he would have looked at the topography of the land, he could have easily determined a much better area to drill or hire a person to witch for water. I then had to spend another $20,000 five years later to drilled another well with Tri-County Pump and Well. They witched the property and found a much better location to drill and produced an excellent producing well! Another time I had them out for a simple repair and the son Mark Harris left my water hose running and drained the entire 2,600 gallon holding tank!!! Even. 6 year old would know enough to turn off the water hose when finished. I have been told he has done this same thing many times!!! Bottom line is Do Not Use this company!!!!!!

A great experience from start to finish. Our well is off-grid and powered by a solar setup. Most…read morepump companies had never even considered solar pumps (i.e. Grundfos), but Guardino were happy to both drill the well, and install the pump and solar. Since the installation, we had a few problems with the solar setup. Augie was always super-responsive, and ensured that any issues were resolved very quickly. This is a company that is about much more than just drilling holes and moving on, their long-term support is excellent.

Drilling a well is kind of like having a root canal. At some point in your life you may need to do…read moreit, but you are never going to look forward to it. Drilling a well is expensive and messy, with the results left mainly to chance. No one will guarantee you will achieve the well yields you are looking for. So, faced with these challenges the last thing you need is the added complexity of hiring a drilling contractor that isn't 100% straight and upfront with you. Let's face it...... most of us will only drill one well in our lifetime, so you will never have the chance to become expert at it. Indeed, we were complete novices. All we knew was our current low producing well was not producing ANY water anymore. Augie from Guardino came up to our property within a day of the first phone call and spent about an hour explaining the process to me. Augie gave us a worst case scenario quote due to the known difficulties of drilling in our area, and despite the large cost and no guarantee of finding water, we went ahead and started the process mainly because I felt confident that we knew what we were getting ourselves into. It felt like we were about to start an adventure together as partners. All permits, and inspections (pre and post) were handled completely by Guardino and all communications were done quickly through email and/or text, which is just perfect for me. We started drilling ahead of the original schedule and experienced a rollercoaster few days, starting with walls collapsing in on very expensive drill bits, to lots of dust and prayers, to the most unlikely and amazing outcome we could ever have imagined. In short, we achieved a staggering 80gals/minute (v's the original goal of 4~5 gals/minute, v's our previous wells 0.5gals/minute output). We achieved this at half the depth we expected, and even with adding a new pump, christy box (as the well was in the middle of a driveway) and pressure tank, we ended up coming in at half the original quote. From first drill to completion took around 5 days, and that included decommissioning the old well. After completion we received all of the required permits and paperwork in both electronic form as well as a nice physical binder so that in future we have all of the info for the well easily at hand. Augie kept checking in on us for a few weeks just to make sure everything was still working as we thought it would. It feels like we have a whole new property as we can now consider growing things and planting real grass for our dogs. In summary, this was a traumatic and stressful process and I don't think anyone should underestimate what it takes to drill a well. However, it was made a painless as possible by having Augie and Guardino with us every step of the way. This review is not for the result. That was up to fate and your mileage will vary greatly depending on your terrain. The review is for the service and support we got from Augie.
