FAQs
What exactly are pinhole leaks and why are they common in Estill Springs?
Pinhole leaks are tiny perforations that develop in water supply pipes—most often in older copper lines—allowing a fine spray or drip of water to escape. In Estill Springs, our slightly acidic municipal water and the area’s naturally high water velocity can corrode the inner pipe wall over time, thinning it until a pin-sized hole forms. Homes built before the mid-1990s that still have Type M copper or galvanized steel piping are at the highest risk.
How do I know if I have pinhole leaks in my home?
Telltale signs include unexplained increases in your water bill, the sound of running water when fixtures are off, damp spots on walls or ceilings, and tiny greenish or bluish stains on exposed copper lines. You might also notice reduced water pressure at certain fixtures. Because pinhole leaks often stay hidden inside walls until damage is done, a professional inspection or pressure test is the most reliable way to confirm their presence.
Why is a whole-house pipe upgrade recommended instead of just repairing each leak?
Once pinhole leaks start appearing in one section of a plumbing system, others usually follow because the entire pipe network is experiencing the same corrosion. Repeated spot repairs mean opening walls multiple times, paying call-out fees, and risking water damage each time a new hole forms. A planned pipe upgrade replaces the failing material in one project, eliminates future leak risk, brings your plumbing up to current code, and often increases home value. Over the long run, a complete upgrade is usually less expensive and far less disruptive than piecemeal repairs.
What pipe materials do you recommend for replacements in Estill Springs, and why?
For most homes we suggest PEX (cross-linked polyethylene) or Type L copper. PEX is flexible, resistant to corrosion and chlorine, withstands freeze-thaw cycles better than copper, and is generally the most budget-friendly choice. Type L copper costs more but offers proven longevity, is 100 percent recyclable, and performs well with our water chemistry when installed with proper dielectric fittings. CPVC can be an option, but we see more homeowners opting for PEX or copper due to better flow characteristics and ease of future modifications.
How long does a typical whole-house repipe take and will I have to move out?
Most single-family homes in Estill Springs can be completely repiped in three to five working days. Water is usually shut off only during certain phases—often a few hours on two separate days—so you do not have to vacate. Our crew protects flooring, walls, and furnishings, and we patch access openings after the new pipe is pressure-tested and inspected. Final drywall and paint touch-ups typically add another day but can be coordinated to your schedule.
Do I need permits or inspections for a pipe upgrade in Estill Springs, and what does it cost?
Yes. The City of Estill Springs and Franklin County require a plumbing permit and an inspection to ensure the new system complies with the 2021 International Plumbing Code and local amendments. As licensed contractors, we secure all permits and schedule the inspections for you. Costs vary with home size, pipe material, and accessibility, but most full repipe projects range from $4,500 to $10,000. We provide a detailed, fixed-price quote after an on-site evaluation and offer financing options to make the upgrade affordable.
