He was able to schedule the work quickly and his team (Jean and two other men) were extremely professional, hard working and thorough. Christian's follow-up through-out the process and after the job was done was excellent. It's only been a few weeks, but we have had a number of storms and no water to be seen anywhere -- even with the 6 day power outage!! Highly recommend for all your waterproofing needs!!

I would highly recommend if you have water issues in your basement or foundation issues, call Sundahl. You will be glad you did. They fix it right the first time.

Throughout the process, they were communicative and easy to work with.

In…read morethe recent round of rain storms, my sump pump stopped working as it is supposed to, and I ended up with about 5 inches of groundwater in the basement. I was able to get the sump pump working again, but 3 days after it stopped raining, I was still getting a lot of water in the pit. I found a sticker for Contractors Waterfproofing, and figured they might of installed the system for the old owners, so I gave them a call. From the moment he picked up Greg was service oriented and responsive. He asked for my address to look up the job, and when he couldn't find it, he called back within 5 minutes to ask what was going on. I explained the problem, and he immediately told me that was normal for my part of town, and told me I just needed to replace the pump and I would be fine. He offered me a price that was half what his competitors charge, but I told him I would do the work myself since I am capable. He then answered a ton of questions about the install, and we had a great conversation about life and how my son could maximize his potential long-term, as he is currently a plumbers apprentice. The bottom line is that the system Greg installed 20 years ago is still working perfectly, and when the pump failed, he not only gave me a fair price, but then walked me through how to do the job myself. This is unheard of in 2025. Greg will get all my business going forward. Thank you.
