Northern Minnesota doesn’t give demolition contractors ideal conditions. It gives them frozen ground, unpredictable shoulder seasons, and structures that have been through decades of frost heave cycles.
In Carlton County, the ground can be locked from November through April. Below-grade footings, basement slabs, and buried utility connections don’t come apart easily when the soil around them is frozen solid. Bring in equipment that isn’t matched to those conditions and the job slows down, costs go up, or something gets damaged that wasn’t supposed to.
The freeze-thaw cycle creates a second problem for structures being cleared in spring. As frost releases unevenly, it shifts what’s left of a structure. Demolition sequencing has to account for that — pulling the wrong element at the wrong time during a thaw event causes problems that a better-planned job avoids entirely.
Cloquet’s Highway 33 corridor is seeing active redevelopment — MnDOT is reconstructing the corridor itself, and commercial properties along it are being cleared for new use. The Scanlon neighborhood has aging residential structures that have been coming down steadily as owners rebuild or sell cleared lots.
Tollefson Excavating demolishes structures in Cloquet the right way — planned for Minnesota conditions, sequenced correctly, and finished clean.
EXCELLENT Based on 30 reviews Posted on Google Becky PembertonTrustindex verifies that the original source of the review is Google. We had some driveway work done and are so happy with the result! Connor returned calls quickly, came out and got us a quote and did the work as soon as road restrictions lifted!! We were out of town when he did the work and he sent us pictures of the progress! He even fixed a walkway issue without adding any cost! Highly recommend Tollefson excavating! Pleasure to work with!!Posted on Google Kayla LarsonTrustindex verifies that the original source of the review is Google. Couldn’t be happier with their work!

Love the personal service Conner provides!Posted on Google Isaiah JohnsonTrustindex verifies that the original source of the review is Google. We had Conner come out to our property to help us complete our hay field restoration project. Conner went above and beyond what was expected. We appreciated his clear communication and vision for what we needed done. We will be using Conner for our future projects and would highly recommend him.Posted on Google Molly JohnsonTrustindex verifies that the original source of the review is Google. Connor is great at what he does! He was professional, fast, and did the job perfectly. Great communication and high-quality work. Would definitely hire them again.Posted on Google Michelle MowryTrustindex verifies that the original source of the review is Google. I hired Tollefson to excavate my garage site (on a hill in Duluth) and remove three tree stumps from site. He did a great job, was easy to communicate with, came out an extra time and fixed an error made when marking site (not his error - contractor error), and made sure my back-fill happened before freeze up! He even seeded and put straw over when he was done.Posted on Google Rakel JohnsonTrustindex verifies that the original source of the review is Google. We hired Tollefson Excavating to dig out our existing pond, which had become overgrown and was turning into an eyesore. Conner completely revitalized it, and the results far exceeded our expectations! The pond looks so much cleaner now, and our family is excited to be able to use it. His skill with an excavator really showed, and he did quality work from start to finish. Overall, we had a great experience working with Conner and would highly recommend Tollefson Excavating to anyone looking for dirt work at a fair price.Posted on Google David JonesTrustindex verifies that the original source of the review is Google. My wife and I felt comfortable right away after meeting Conner at our new home construction site. Not only did he do a fantastic job with site clearing, excavating and grading our new home site, Conner was there at our site the day he said he would be there. That was huge. I will highly recommend Conner to anyone looking for a reliable excavator.
From residential projects to commercial developments, we provide end-to-end solutions for every stage of construction.
Every demolition job starts before the machine arrives.
Utility disconnection is the first step on every Cloquet demolition — no exceptions. Gas, electric, water, and sewer have to be properly disconnected and capped before any structure comes down. We coordinate with utility providers and Minnesota Gopher State One Call to confirm all services are off and lines are marked. Skipping this step doesn’t save time. It creates safety incidents and permit problems that shut the job down.
Permit requirements for Carlton County and the City of Cloquet are handled upfront. We identify what’s required for your specific project before work begins so there are no stops mid-job.
Demolition is sequenced based on structure type and site conditions. Full teardown for structures being completely removed. Selective demolition where only portions need to come down. Foundation removal if the site is being rebuilt or the footprint needs to change.
All debris is hauled off. We don’t leave piles. Backfill and compaction follow foundation removal where needed, and final grade is set so the site is clean, stable, and ready for the next contractor or the next use.
A property owner along Cloquet’s Highway 33 corridor needed a commercial structure cleared for redevelopment. We coordinated utility disconnections, pulled the required Carlton County permits, demolished the structure, and hauled all debris off site. Foundation was removed and the lot was backfilled and graded to a clean, level finish. New construction contractor had a site-ready lot within the agreed project window — no debris, no delays.
A Scanlon homeowner needed an aging 1950s-era house demolished and the lot cleared for a new build. Freeze-thaw conditions in early spring required careful sequencing around the foundation removal — we timed the below-grade work for stable ground conditions after the frost released. Structure down, foundation out, lot backfilled and graded. New construction started on schedule with a clean, compacted pad.

Above-grade demolition can proceed through most of a Carlton County winter. Below-grade work — foundation removal, utility capping, and excavation — is more dependent on frost depth and ground conditions. We assess timing based on the specific scope and advise on sequencing so you’re not waiting longer than necessary.
Permit requirements vary by structure type and location — city of Cloquet and Carlton County each have their own processes. We identify what’s required for your specific project before work begins and handle the permit process as part of the job. No surprises mid-demolition from missing approvals.
Yes. All debris is hauled off site — we don’t leave piles. Foundation removal, backfill, and compaction are included where the site requires it. Final grade is set before we leave. You get a clean, stable lot ready for the next phase, not a cleared footprint with a hole in the middle.
Older structures in Cloquet and the Scanlon neighborhood — particularly those built before 1980 — may contain asbestos or lead-based materials that require testing and abatement before demolition. We identify this risk during the pre-demolition assessment and coordinate with licensed abatement contractors before any structure comes down. This step is required by Minnesota regulations and protects everyone on the job.
Yes. We’re familiar with the Highway 33 corridor and the active MnDOT reconstruction work in the area. Demolition near an active construction corridor requires coordination on access, debris hauling routes, and timing. We handle that coordination upfront so the job doesn’t create conflicts with the adjacent roadwork.
