Questions and Answers
My older D.C. home had plumbing replaced during a renovation, and now I'm having issues. Can you help?
Absolutely. We frequently see problems stemming from poorly installed replacement plumbing in renovated D.C. row houses and older buildings. Our team is skilled at diagnosing these issues, whether it's incorrect pipe sizing, faulty joints, or improper venting. We'll provide a clear assessment and a lasting repair that respects the structure of your home, backed by our one-year workmanship warranty.
Do you offer free estimates for plumbing repairs or installations?
Yes, we do. We believe in transparent pricing from the start. You can get a free phone quote by describing your issue, whether it's a leaky faucet, a planned installation, or an emergency repair. There are no hidden charges, and we honor the quoted price. For more complex jobs, we may provide a detailed in-person estimate to ensure accuracy.
What does your one-year warranty on workmanship cover?
Our warranty covers the quality of our installation or repair work for a full year. If an issue arises due to our workmanship within that period, we will return to fix it at no additional cost. This warranty applies to all our services, from garbage disposal installations (where we're In-Sink-Erator Pro Circle members) to sewer line repairs and water pipe replacements, giving you peace of mind.
