Testimonials
Alice Howard
⭐️⭐️⭐️⭐️⭐️ We had a water main break on our property and needed someone fast. Hagstrom Excavating showed up within hours, dug the trench safely and cleanly, and worked hand-in-hand with the plumber to get everything back online. What could’ve been a nightmare turned into a smooth fix. They really saved us from a major headache.
Nathan Marshall
⭐️⭐️⭐️⭐️⭐️ I was really impressed with Hagstrom’s trenching work. They dug a long run for gas and power lines, and everything was clearly marked, dug safely, and backfilled neatly. They communicated with me throughout the whole process, which I appreciated as a homeowner. I’ve had contractors leave a mess behind — not these guys. Top-tier service.
Ema Romero
⭐️⭐️⭐️⭐️⭐️ I had an incredible experience with Hagstrom Excavating and Septic Tank. From the first phone call to the final inspection, they were professional, efficient, and transparent. They replaced our aging septic system on schedule and kept me in the loop every step of the way. The crew was respectful of our property and cleaned up after themselves better than I expected. I’d recommend them to anyone looking for reliable, high-quality work.
Ann Smith
These guys are lifesavers! We ran into an issue with our system and called Hagstrom Excavating on a recommendation. They were out the next morning, diagnosed the problem quickly, and had everything fixed before the weekend. Super friendly, honest about pricing, and didn’t try to upsell us on anything unnecessary. I felt like I was in good hands the whole time. Thanks again for the great service!
