Q&A
What are the most common causes of slow bathroom drains and toilet leaks in older Mahopac homes?
In many Mahopac homes, bathroom drains often slow down due to a buildup of hair, soap scum, and mineral deposits from our local water. Toilet seal leaks, which can cause water damage and higher bills, are frequently due to worn wax rings or loose connections at the base. With 30 years of experience in the area, DeGasperi & Son can quickly diagnose these specific issues. We perform thorough plumbing inspections to identify the root cause and provide lasting repairs, whether it's a professional drain cleaning or resealing your toilet to prevent future problems.
Do you handle both plumbing and heating system installations, like for a full bathroom remodel or a new boiler?
Yes, we provide complete solutions. As a full-service plumbing and heating contractor, we can manage every aspect of your project. For a bathroom remodel, that includes the installation of new showers, tubs, sinks, toilets, and faucets, as well as any necessary plumbing rough-in. For heating, we are certified for gas and propane installations and specialize in boiler and water heater replacements, including oil-to-gas conversions. This integrated approach, backed by our decades of experience, ensures all systems work together efficiently for your Mahopac home.
My water heater is failing. What are my options, and do you offer emergency service for this?
We specialize in water heater services and can help you choose the right unit for your home, whether it's a conventional tank model or a more efficient tankless system. We handle the full installation, including any necessary gas line or water pipe work. If your heater fails suddenly, we offer emergency plumbing service seven days a week to get your hot water restored quickly. We provide free estimates for all replacement options, so you can make an informed decision without pressure.
