Go to company if you're in need of a well. John and Josh are hard working professionals that get the job done fast but take the time to explain and answer any questions you might have. Great crew and great company. Couldn't be more pleased!

Our sand point well near Grantsburg, WI went bad. We contacted McCullough on 7/15. They were able to work us in between some other jobs in the area and came out on 7/22 drilled the well, did the first disinfection. 7/23 they came back connected the new well to the house, sealed the old well, did the second disinfection which included our plumbing (faucets, shower\tub, etc.) Both teams where professional and extremely competent. The response time was excellent. I cannot say enough good about these guys!

These guys are well experts and good people. Came all the way out to our house but it was a minor issue so they said they wouldn't feel right charging us. They were not the ones who did our well but they will still answer questions and try to give us answers. In the future I will never use any one else.

Helpful from the first phone call all the way through. They got someone out the same day, with all the parts needed, and fixed in one trip. Jon was fast but not hurried, and happily explained what he was doing to I could understand. Very reasonable cost. Will definitely use again (hopefully not soon though ).

We use McCullough And Sons for all are well fixes. I had water then no water, they came out and checked the well tank and switch first. I had them replaced within the last year. They pulled up the pump and showed me how little pressure it was pumping. We agreed I needed a new pump and then showed how much pressure there was before they dropped it down the casing. Very professional and friendly.

When the water pressure disappeared, and we realized it was the well pump and not something else, we found McCullough (our 2nd call). The after hours automated answering service gave us JJ's number - thank God! Not only did he answer the call that evening when everyone else was either closed or giving after hours pricing, but gave us a reasonable ballpark price for a new pump, called back and came out the following morning. He subsequently found out it was a mouse who ate through the wires under the well-cap. Thankfully it was not the "shockingly" high price we had to brace ourselves for, but

Came out and replaced the pump same day in near 100 degree heat. Mike did a fantastic job. I have never written a review before today. Darn impressive work by Mike. Thank You.
