Q&A
What's the most common cause of drain clogs in older Baltimore homes, and how do you fix them?
In many of Baltimore's historic homes, the most common culprits are mineral buildup from hard water and accumulations of grease, hair, and soap scum in older pipes. Our drain repair service starts with a thorough video inspection to pinpoint the exact location and cause of the clog. We then use professional-grade hydro-jetting to clear the blockage completely and clean the pipe walls, which is more effective and less invasive than traditional snaking for these persistent local issues.
I have an old pipe that's leaking. Can you repair it, or does the whole line need replacing?
It depends on the condition of the pipe. During a plumbing inspection, we assess the material (like galvanized steel common in older Baltimore homes), the extent of corrosion, and the leak's location. Often, a section of water pipe repair is sufficient. However, if we find widespread deterioration, we might recommend a partial or full repipe with modern materials like copper or PEX to prevent future leaks and protect your home from water damage. We'll always explain your options clearly so you can make the best decision for your home.
My water heater is old and inefficient. What should I consider for a replacement in my Baltimore row house?
Space is often a key consideration in Baltimore row houses. We'll discuss the best type—traditional tank, high-efficiency tank, or tankless—for your specific household size and utility setup. Our water heater installation service includes helping you choose the right size and model for efficiency, ensuring proper venting (especially important for gas lines), and handling all permits and connections. A new, properly sized unit can provide reliable hot water and significantly lower your energy bills, which is a great upgrade for any local home.
