Great family run business. I used them in July 2013 when we were looking at a property in Napa and…read morethey provided a written inspection and estimate for repairs. In August 2021 we had a problem with our well (turned out to be a leaky pipe) and Nick and another guy came out and quickly found the problem and fixed the pipe and then suggested we pull all the pipe and inspect the pump and it turned out to be 30+ years old so they replaced the Grundfos pump with the same brand/model the same day. Total bill was under $3k. Very fair for the area. There was a little damage to the lawn (back tires of the truck sank in the lawn a bit) but I was able to fill in with dirt and seed and looks good now. Nick warned me there may be damage ahead of time as our well is near our lawn and the only place to park the truck was on our lawn. Months later I needed the work details and I emailed and Pam quickly replied with a copy of our invoice and details on our well (well depth, pump depth, etc).

Roy and Nolan ( father and son) did the job. Their price was 30% less than other company bidding for the job. They were honest and pleasant person to work with.

Now after three years I applied to build new house and granny unit. I called them to do some dry well test and they were here in my property taking care of well test within no time. Such a sweet and kind people. I highly recommend.

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.

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.
