Frequently Asked Questions
What's the most common plumbing issue you see in older Spearfish homes?
We frequently address pipe corrosion and garbage disposal jams in older Spearfish homes. The local soil and water conditions can accelerate corrosion in older metal pipes, leading to leaks, reduced water pressure, and eventual failure. For garbage disposals, improper use often causes jams. Our plumbing technicians are experienced in diagnosing these specific local issues. We can perform a thorough plumbing inspection to assess pipe condition and provide repair or replacement options, and we can safely clear or repair jammed disposals to restore your kitchen's functionality.
My drains are slow. Do you just snake them, or is there more to it?
At Northern Hills, we go beyond a simple snaking. Our drain cleaning service starts with a complete survey of your pipe's condition using industry-standard methods. We identify whether the clog is from grease, roots, or a broken pipe. Based on what we find, we'll recommend the right solution—which could be hydro jetting for a thorough clean, rodding, or even a targeted drain repair if there's damage. This diagnostic approach ensures we fix the real problem, not just a symptom, helping prevent future clogs.
When is excavation necessary for a sewer line problem?
Excavation and trench digging become necessary when a sewer line is severely damaged, collapsed, or has root intrusion that can't be resolved with repair techniques like lining. This is common for older lines made of clay or corroded cast iron. Our technicians will first conduct a detailed inspection, often with a camera, to assess the damage. If excavation is the best long-term solution, we handle the entire process—from precise trench digging and sewer installation or replacement to careful site restoration—ensuring your new line is installed correctly and built to last.
