FAQs
What are the most common signs of a mysterious plumbing leak in my Walland home?
Unexplained increases in your City of Maryville Utility bill, the sound of running water when fixtures are off, damp or warm spots on floors, mildew odors, and discoloration on walls or ceilings are typical warning signs. Even a small pinhole leak can waste hundreds of gallons a month, so calling us for an inspection as soon as you notice any of these indicators can prevent major water damage.
How do you locate hidden leaks before recommending a pipe upgrade?
Our technicians use electronic leak detection equipment, infrared thermal imaging, and in-line video cameras. These tools let us pinpoint the exact location and severity of the leak without tearing into your walls or slab. Once we know the scope, we can tell you whether a localized repair or a complete pipe upgrade will be more cost-effective and durable.
When should I choose a full pipe upgrade instead of spot repairs?
If your home still has 30-plus-year-old galvanized steel or polybutylene lines, experiences frequent leaks, or has water quality issues due to corrosion, replacing the entire system is usually the smarter investment. Multiple repairs add up quickly, and aging pipes can fail unpredictably. A whole-house upgrade gives you new-pipe peace of mind, complies with current Blount County codes, and typically comes with a 25-year parts warranty.
What pipe materials do you recommend for upgrades in Walland, and why?
We primarily install Type L copper and PEX-a tubing. Copper is time-tested, resists UV light, and adds resale value. PEX-a is flexible, freeze-resistant, quieter, and often less expensive to install because it requires fewer fittings. Both meet Tennessee plumbing codes, are lead-free, and carry manufacturer warranties of 25 years or more. During your consultation, we’ll explain which option—or combination—best fits your budget, water chemistry, and home layout.
How much does a pipe upgrade cost and how long will the project take?
Costs vary with square footage, number of fixtures, and material choice, but most Walland homes fall between $4,500 and $9,500 for a complete repipe. We provide a written, no-surprise estimate after inspection. A typical single-story house can be upgraded in two to three days; two-story homes or those with extensive drywall may take up to a week. We handle permitting, protect floors and furnishings, and leave your home water-ready each evening.
Will upgrading my pipes raise my property value or lower my insurance premiums?
Yes. Modern piping eliminates the risk factors insurers associate with galvanized, polybutylene, or deteriorating copper lines, so many carriers offer lower premiums once proof of repiping is provided. Real-estate agents also report that a recent repipe can boost resale value and reduce time on market because buyers know they won’t face hidden plumbing expenses. We supply all documentation and warranties you’ll need for your insurer or prospective buyer.
