If you’re searching for a construction company in the Quad Cities, you’re probably tired of the same routine, leaving voicemails that never get returned, getting wildly different quotes for the same job, or finding out three weeks in that the “contractor” you hired is subcontracting everything to whoever’s cheapest that week
That’s not how we work. Northstar Construction is a locally owned construction company based in Moline, building and remodeling homes and commercial spaces across the Quad Cities, Moline, Rock Island, East Moline, Davenport, and Bettendorf. We pick up the phone. We give you a clear estimate. We do the work with our own crew. And we finish when we said we’d finish.

We’re a full-service construction company, which means we handle projects from concept through final walkthrough: design, permits, demo, framing, mechanicals, finishes, and cleanup. Below are the services Quad Cities homeowners and businesses hire us for most often.
First-floor expansions, in-law suites, sunrooms, mudrooms, and family room additions for homeowners who love their neighborhood but need more space.
Doubling your square footage without changing your address. The smartest option when your lot is tight or you don’t want to lose yard space.
Kitchen Remodeling
Layout redesigns, cabinet installs, countertops, lighting, and full gut renovations.
Bathroom Remodeling
Master suites, walk-in showers, accessibility upgrades, and full bath build-outs.
Whole-Home Remodels
Top-to-bottom transformations for older Quad Cities homes that need to be brought into this century.
Exterior Renovations
Siding, windows, doors, and curb appeal projects that hold up to Midwest winters.
New Home Construction
Custom builds from the foundation up across the Quad Cities region.
Garage Construction
Detached and attached garages, including oversized builds for workshops and storage.
Most construction companies will tell you they’re “the best.” We’d rather just show you what makes the day-to-day different when you work with us:
Local crews, not subcontractor roulette.
Our team works on your project. That means consistent quality, accountability, and someone you can actually talk to on-site.
Licensed in Illinois and Iowa.
We’re fully licensed, bonded, and insured on both sides of the river, which matters more than people realize when you’re remodeling in Bettendorf versus Moline.
Fixed-scope estimates.
We don’t lowball to win the bid and then nickel-and-dime you with change orders. The estimate you sign is the price you pay, barring real scope changes you approve in writing.
Honest timelines.
We tell you what your project will actually take, including time for permits and inspections. If something slips, you hear it from us first, not when you ask three weeks later.
Workmanship that holds up.
Most of our work comes from referrals and repeat clients. That only happens when projects don’t fall apart in year two.
The Quad Cities isn’t just one market. It’s five distinct cities across two states, and every one of them has its own permitting process, building codes, and architectural personality. We’ve worked in all of them, and we know what each city’s inspectors actually look for.
Our home base. We’ve built and remodeled homes throughout Moline, from the historic neighborhoods near Prospect Park to newer builds in the south end. We know Moline’s permit timelines, the local inspectors, and how to work efficiently in older homes with knob-and-tube wiring and balloon framing.
Rock Island, IL
Rock Island’s housing stock skews older, which means projects there often involve more discovery work. Original plaster, outdated electrical, foundations that need attention before the fun stuff starts. We don’t dodge those projects. We plan for them. Whole-home remodels and additions are where we add the most value in Rock Island.
Davenport, IA
Crossing the river means crossing into Iowa code, and that catches a lot of construction companies off guard. We’re licensed in Iowa, familiar with Davenport’s permitting office, and have completed projects from the Village of East Davenport to the developments further west off Locust Street. Whether it’s a second-story addition in a McClellan Heights bungalow or a kitchen remodel near Eastern Avenue, we know the terrain.
Bettendorf, IA
Bettendorf homeowners tend to invest in their homes for the long haul, and the projects there reflect that: larger additions, high-end kitchens and baths, custom builds. Our work in Bettendorf focuses on craftsmanship that matches the investment level and finishes that hold up over decades, not seasons.
East Moline, IL
East Moline projects often involve smart, value-driven remodels. Improving older homes without overbuilding for the block. We help homeowners there make the right calls on where to spend and where to save.
We’ve refined our process to eliminate the surprises that make construction projects miserable. Here’s exactly what happens when you hire us:
We come out to your property, listen to what you actually want, and walk through the scope. No pressure, no "limited-time" pricing games.
You get a line-by-line breakdown of materials, labor, allowances, and a realistic timeline. If there are unknowns, we name them upfront instead of burying them in a change order later.
For larger projects, we work through layout, materials, and selections before swinging a single hammer. Decisions made on paper are 10x cheaper than decisions made mid-project.
We pull every permit your project requires, whether you're in Moline, Davenport, or anywhere in between, and schedule inspections so they don't bottleneck the build.
Our crew shows up when they say they will, keeps the site organized, and communicates daily progress. You'll know what's happening on your property every step.
We walk the project with you, address anything that needs attention, and don't disappear after the check clears.

Yes. We’re licensed in both states and regularly work in Moline, Rock Island, East Moline, Davenport, and Bettendorf. The permitting and code requirements are different on each side of the river, and we handle all of it for you.
Yes. Fully licensed in Illinois and Iowa, bonded, and carrying both general liability and workers’ compensation insurance. We can send you current certificates before the project starts.
It depends entirely on scope. A bathroom remodel might run 3 to 5 weeks. A kitchen remodel runs 6 to 10 weeks. A home addition or second-story addition typically takes 3 to 6 months. We give you a realistic timeline in writing before you sign anything, and we update you immediately if anything changes.
Our core trades (framing, finish work, project management) are in-house. For specialized trades like electrical, plumbing, and HVAC, we work with a small group of licensed Quad Cities subcontractors we’ve used for years. We don’t shop those trades out to whoever bids lowest that week.
Yes. We pull every permit your project requires and coordinate inspections. You don’t need to deal with the city’s permitting office. That’s our job.
We can talk through financing options that fit your project budget. Most homeowners use a combination of savings, home equity, or renovation-specific lending. We’ll point you toward options that make sense for the size of your project.
Call (309) 519-4677 or fill out the contact form on our site. We’ll schedule a free on-site consultation, walk through your project, and get you a detailed written estimate within a few business days.
Whether you’re remodeling a kitchen in Moline, adding a second story in Bettendorf, or building out a retail space in Davenport, we’re ready to help you get it done right.
The first step is a conversation. No pressure, no sales pitch. Just a clear answer on whether your project is something we can help with, what it’ll realistically cost, and how long it’ll take.
