Frequently Asked Questions About Plumbing in Dekalb

Get answers to common questions about plumbing services in Dekalb, Illinois.

1What are the most common plumbing issues for Dekalb homeowners, especially related to our climate?

The most frequent issues stem from our harsh Illinois winters, including frozen and burst pipes in poorly insulated crawl spaces or exterior walls. In older homes in areas like the historic district, we also commonly see sewer line problems due to aging clay pipes and tree root intrusion. Spring and fall are ideal times for preventative maintenance to avoid winter emergencies.

2How do I choose a reputable plumber in Dekalb, and are there specific local licenses I should verify?

Always choose a plumber licensed by the State of Illinois Department of Public Health; you can request their license number. For Dekalb-specific work, especially sewer line repairs that may involve city right-of-way, ensure they are familiar with local municipal codes and have a good relationship with the DeKalb Public Works Department. Check for local reviews and membership in organizations like the Kishwaukee Valley Builders Association.

3What is the typical cost range for common plumbing services in the DeKalb area?

Costs vary, but regional averages are: $150-$450 for a standard service call and repair (like a faucet or toilet), $1,000-$4,000 for a water heater replacement (including Illinois code compliance), and $3,000-$8,000+ for major sewer line repair, which is common here. Pricing is influenced by the age of your home, accessibility, and the need for specialized equipment to navigate our local soil conditions.

4Why is my basement floor drain backing up, and is this a city sewer or my home's responsibility?

In DeKalb, if multiple fixtures in your home are backing up simultaneously, it's likely a blockage in your private lateral sewer line, which is the homeowner's responsibility. If the problem is isolated, it could be an internal issue. The City of DeKalb is responsible for the main sewer line in the street. A local plumber can perform a camera inspection to pinpoint the location and responsibility, which is crucial before contacting the city.

5When should I consider repiping my older DeKalb home, and what materials are best for our water?

If you have frequent leaks, discolored water, or significantly low water pressure in an older home (common with original galvanized steel pipes), repiping is advisable. For DeKalb's water supply, durable options like copper or cross-linked polyethylene (PEX) are excellent. PEX is particularly resistant to freezing, a valuable trait for our climate, and is often more cost-effective for whole-house repiping projects.
