Frequently Asked Questions

1) Do you offer residential and commercial plumbing and excavation in Northern Colorado?
Yes. OnGrade Plumbing & Excavation provides residential and light commercial plumbing and excavation across Northern Colorado. We handle everything from water heaters and filtration to sewer issues, hydro jetting, gas lines, septic, and underground water service line work. One crew manages both the digging and the pipe work so projects move faster and stay code-compliant.
Common signs include unexplained high water bills, low water pressure, wet or sinking spots in the yard, and water sounds when fixtures are off. Underground leaks can also cause foundation or landscape damage over time. We can locate the issue, confirm whether repair or replacement is best, and restore the area with proper backfill and compaction.
If your water heater is leaking, producing rusty water, making loud popping sounds, or struggling to maintain temperature, replacement is often more cost-effective. Age also matters, especially if the unit is near the end of its expected service life. We help you choose tank or tankless options, size the system correctly, and install it to code for safe, reliable hot water.
Hydro jetting is a high-pressure drain and sewer cleaning method that scrubs pipe walls to remove grease, roots, and scale. It is ideal for recurring clogs, slow drains, and heavy buildup that a standard snake may not fully clear. Jetting restores flow and helps reduce repeat backups, especially for kitchens, laundry lines, rentals, and HOA systems.
Yes. We handle sewer and water service line repair and replacement, including underground pipe work that requires excavation. Our team can assess the line condition, recommend a targeted repair or full replacement, and complete the job with pressure testing and inspection-ready workmanship. We also coordinate permits when required.
Yes. We install and repair gas lines for furnaces, water heaters, ranges, dryers, fireplaces, and outdoor features like grills, patio heaters, and fire pits. Proper sizing and pressure testing are critical for safe operation and code compliance. We ensure clean routing, secure connections, and inspection-ready results.
Yes. We provide septic diagnostics, repairs, and pumping coordination, and we can support compliant installs when needed. If you notice odors, slow drains, or soggy areas in the yard, your septic system may need attention before a backup happens. We troubleshoot tanks, baffles, pumps, and drainfields and recommend practical solutions that protect your property.
Some plumbing and excavation projects require permits, especially for water service lines, sewer work, gas lines, and certain equipment replacements. Requirements vary by city and county in Northern Colorado. We can help confirm what is needed, coordinate inspections, and complete work to code so your project stays compliant.
Timelines depend on the scope, access, and whether permits or inspections are required. Smaller repairs can often be completed the same day, while underground line replacements and septic work may take longer due to digging and restoration. We provide a clear plan and schedule window so you know what to expect before work begins.
Routine maintenance makes a big difference. Avoid flushing wipes, manage grease and food waste, keep an eye on water pressure, and address small leaks early. For homes with recurring clogs or older lines, preventive hydro jetting and camera inspections can reduce emergency calls. We can recommend a maintenance plan that fits your property and usage.
