FAQs
How can I tell if my Collegedale home still has galvanized steel supply lines?
Homes built before the mid-1960s in Collegedale often used galvanized steel. Look for dull-gray, threaded pipes in basements, crawlspaces, or utility rooms. A magnet will stick to galvanized steel but not to copper or plastic. Other clues include brown or yellow water after the tap has been off, chronically low water pressure, or flaky rust on exposed sections. Our free in-home assessment can confirm pipe material without cutting into walls.
What problems are caused by aging galvanized pipes?
Galvanized pipes corrode from the inside out. As zinc lining erodes, iron rusts and narrows the waterway, leading to reduced flow, temperature fluctuations, and discolored or metallic-tasting water. Corrosion can also trap lead from old solder or fixtures, creating a potential health risk. Eventually the pipe walls thin to the point of pin-hole leaks or catastrophic bursts, which can cause extensive water damage.
Which replacement materials do you recommend for upgrading galvanized lines in Collegedale?
We typically recommend Type L copper, PEX-A or PEX-B cross-linked polyethylene, or CPVC. All three meet Tennessee and IPC plumbing codes. Copper offers 50-plus-year life and heat resistance, while PEX is flexible, freeze-tolerant, and often requires less wall demolition. CPVC is a cost-effective rigid option. During your consultation we compare price, life expectancy, and installation impact so you can choose the best material for your budget and house layout.
Do I need a permit or inspection to replace galvanized pipes in Collegedale?
Yes. Hamilton County/City of Collegedale requires a plumbing permit for any whole-house re-pipe or major alteration. A licensed plumber must submit plans, perform the work, and schedule rough-in and final inspections where a pressure test is observed by the inspector. Our team handles all permitting and coordinates inspections so your project is fully code-compliant and documented for future real-estate transactions.
How disruptive is a whole-house re-pipe and how long will it take?
Most single-family homes with two bathrooms can be re-piped in 2–3 working days. Water service is usually shut off only during work hours; we turn it back on each evening. We protect floors and furnishings, cut minimal access holes, and, when using PEX, can often snake lines through existing cavities to reduce drywall removal. After pipe installation, we patch, texture, and prime wall openings. You can typically stay in the home throughout the project.
What does a galvanized-to-modern piping upgrade cost and do you offer financing?
In Collegedale, a full re-pipe generally ranges from $4,000 for a small one-bath cottage to $12,000 or more for large multistory homes, depending on square footage, number of fixtures, material choice, and accessibility. Our quotes include permits, materials, labor, drywall repair, and a 25-year parts-and-labor warranty. We partner with local lenders to provide 0 % interest for 12 months or low-interest plans up to 60 months, subject to credit approval, so you can upgrade without delaying other priorities.
