Water Line Installation & Repair

Clean, reliable water service starts underground

The water line running from the municipal main to your home or business is one of the most important — and most overlooked — pieces of infrastructure on your property. A single compromised section can mean low pressure, discolored water, skyrocketing water bills, or flooding. Blair Excavation Inc. handles water line installation, replacement, and leak repair for residential and commercial clients in Lakewood, IL and throughout the greater Chicago area.

Water service and water main work is one of our two specialties (alongside sewer), and our crews work on underground utility lines year-round. We handle the excavation, the pipe work, the backfill, and the site restoration — one team, one point of contact, one quote.

Water line services we provide

• New water service installation — code-compliant water service for new construction and additions.
• Water line replacement — swapping out aging galvanized, polybutylene, or lead lines with modern copper or PEX-tested materials.
• Water main repair — fast response to leaks, breaks, and pressure issues.
• Water service tap-ins — coordinated connections to the municipal main, with permits and inspections handled.
• Commercial water lines — larger-diameter service for multi-tenant, retail, and light-industrial sites.
• Shut-off valve replacement — curb stops, B-boxes, and interior shut-off relocation.

Signs of a water line problem

Underground water leaks often hide for weeks before anyone notices. Watch for these red flags:

• Unexplained spike in your water bill with no change in usage
• Low water pressure throughout the house or building
• Discolored, rusty, or cloudy water at the tap
• Wet or unusually lush patches in the yard along the service line
• Water pooling near the curb stop or meter pit
• Whistling or hissing sounds near the main shut-off

Why choose Blair for water line work

Water lines run under driveways, sidewalks, landscaping, and sometimes under the house itself. The difference between a clean job and a messy one is experience with the dig. Our crews excavate carefully, protect surrounding hardscape and plantings, and restore the site after the line is pressure-tested and the inspector has signed off.

We're licensed and insured, familiar with the municipal permit process across McHenry, Kane, Lake, and Cook counties, and we handle emergency calls when a line breaks. Whether you need a new service for a custom home, a full replacement on an older property, or quick repair before the basement floods, we're the call.

Where we work

Water line service is available throughout Lakewood and the 30-mile service area around it — Crystal Lake, Woodstock, McHenry, Algonquin, Huntley, Cary, Elgin, Barrington, and the surrounding communities.
