Frequently Asked Questions
What should I do if my Wilmington home has a sewer backup after heavy rain?
Coastal flooding and heavy rain in our area can overwhelm sewer lines. We recommend calling us immediately to prevent water damage and health hazards. Our long-time plumbing technicians are experienced with Wilmington's specific drainage challenges. We can perform a thorough inspection to diagnose the cause, clear the blockage, and discuss solutions like line repairs or replacements to help prevent future backups.
Does Calfo & Haight install its own ductwork for new HVAC systems?
Yes, we do. For every new HVAC installation or replacement, we fabricate and install our own custom sheet metal ductwork. This ensures the ventilation system is perfectly sized and sealed for your home, bringing it up to current codes. Doing this work ourselves allows for better quality control, improves system efficiency, and can help lower your overall energy costs.
My family has used your services for years. How do you maintain consistent quality?
Thank you for your trust. Our consistency comes from our people. Many of our technicians have been with us for decades, treated as part of the family. This deep experience, combined with the hands-on involvement of the Calfo family across generations, means every job is approached with the same care and commitment to honest, friendly service that has defined us since 1967.
