Get answers to common questions about plumbing services in Delaware, New Jersey.
In our region, winter freeze-ups are the top seasonal concern; always insulate pipes in unheated areas like crawl spaces and garages, and disconnect outdoor hoses before the first hard freeze. Late summer and fall often bring sewer line backups due to invasive tree roots seeking moisture; consider having your main sewer line inspected with a camera if you have mature trees near the line. Spring thaws can also reveal leaks from winter damage, so check for moisture in basements and under sinks.
Yes, labor rates and overall costs are generally higher in most of New Jersey compared to Delaware, influenced by higher business operating costs and insurance requirements. For common repairs like fixing a leaky faucet or running toilet, homeowners can expect to pay between $150-$350, while emergency services like a burst pipe repair or water heater replacement on a weekend can range from $500 to over $2,000, depending on parts and complexity.
First, verify their state-specific license is current (Delaware requires a Division of Professional Regulation license, NJ requires a State Board of Master Plumbers license) and that they carry both general liability and worker's compensation insurance. For local reliability, choose a company with a strong, long-standing reputation in your specific county or town, as they will be most familiar with local code variations, common soil issues affecting sewer lines, and municipal water system characteristics.
In both Delaware and New Jersey, the homeowner is typically responsible for the sewer lateral—the pipe running from your house to the municipal sewer main under the street. If multiple fixtures in your home are backing up simultaneously, it's likely a blockage in your lateral. You should contact a plumber for a camera inspection; only contact your local public works department if neighbors are experiencing identical issues, which could indicate a main line problem.
Both states have strict codes requiring permits and inspections for water heater replacements to ensure proper safety measures like pressure relief valve piping and seismic strapping (especially in NJ) are followed. Furthermore, due to our region's hard water, many local codes now emphasize the installation of an expansion tank to protect your plumbing system from thermal expansion pressure, which a licensed professional will handle as part of a compliant installation.
