(320) 212-8326

Business Overview

Located just off Highway 12 near the Willmar Community Center, A1A Construction has been a reliable partner for local homeowners and businesses for years. We understand that Willmar's harsh winters, freeze-thaw cycles, and heavy spring rains often cause concrete slabs to shift and heave, leading to cracked or uneven floors in basements, garages, and entryways. Our team specializes in professional floor installation that not only fixes these issues but prevents future damage by ensuring a stable, level surface. Whether you're updating a home near Robbins Island, renovating a storefront downtown, or building a new shed on the south side of town, we use materials that stand up to Minnesota weather. As general contractors, we also coordinate fencing and gate repairs that often accompany property resets after a floor repair. We’re here to help keep your home safe and functional through every season.

Question Answers

Why do my floors become uneven or cracked every winter in Willmar?

The main cause is frost heave. When the ground freezes and thaws repeatedly during Minnesota winters, the soil expands and contracts, putting pressure on concrete floor slabs. In Willmar, this is common in older homes with slab-on-grade foundations or uninsulated garages. If you notice cracks, sagging, or a sloped feeling in your floor, it's often a sign of shifting subbase. A1A Construction can assess the foundation, stabilize the base, and install a new, level floor that resists future movement.

Can you fix a cracked garage floor and also repair the fence that got pushed out of alignment?

Absolutely. As a general contractor, we handle both jobs in one visit. If a heaving concrete slab has pushed your fence posts out of plumb, we can first level and reinstall the floor, then reset the fence posts on a stable base. This is a common issue in Willmar neighborhoods with attached garages and chain-link or wood fencing. We make sure everything is square and secure so you don't have to call two different companies.

What is the best flooring solution for a Willmar basement that has moisture issues?

For basements that see seasonal dampness or minor water seepage (common near the lakes and wetlands around Willmar), we recommend luxury vinyl plank (LVP) or tile over a properly prepared, moisture-resistant subfloor. These materials hold up well to humidity and temperature swings, and they hide minor imperfections in a concrete base. If the slab itself is cracked or settling, we can repair and level it before installation to ensure long-lasting results.
