Serving the Stateline area with clean installs and steady communication.
Border-town weather can be rough—river winds, hail, summer heat, and deep winter freezes. Castle Contracting repairs and replaces roofs, installs siding and seamless gutters, upgrades windows and doors, and builds decks, patios, and fences with careful prep and organized job sites. Expect a clear scope, progress photos, and a schedule that fits your plan in South Beloit and nearby neighborhoods.
From Blackhawk Blvd. to neighborhoods near the river, we use proven materials, protect landscaping, communicate daily, and keep sites clean from tear-off to final sweep. A nearby crew means faster scheduling and fewer surprises—plus support after the job is done.

We work across South Beloit and the Rock River corridor. If a storm hits, we document conditions with photos, explain repair vs. replacement options, and outline next steps so you can decide with confidence. You’ll get an itemized proposal and a realistic timeline.

Hidden issues often sit in valleys, ridge caps, vents, soft metals, chimney and sidewall flashing. Our assessment checks shingles, underlayments, siding, gutters, and more so important items aren’t missed. You’ll receive a clear report and a practical plan for your South Beloit home.

I would recommend Castle in a heartbeat. Brad and Chris were awesome to work with. The dream of having a front porch came to reality and we are so enjoying it. All their workers were great and so nice.
Thank you Castle for a job well done.

Chuck with Castle is amazing! He really works for the customer and try’s to get them the most for their money and fights insurance companies for the client. We have had him work on several of our businesses and home and we won’t call anyone else!

Working with Castle Exteriors was truly exceptional! Our roof replacement was seamless, and the results exceeded our expectations. Trevin, our sales associate, was a pleasure to work with, professional, honest, and dependable throughout the process. We couldn't be happier with the outcome and highly recommend Castle Exteriors, especially Trevin, for their outstanding service!
