Get Same-Day Drain Cleaning Services

Clogged drains can cause headaches and unwanted backup in your sink, bathtub, or sewer line. When you notice slow-draining water, foul odors, or gurgling sounds, it is time to take action. Castlewood Plumbing uses advanced techniques such as hydro jetting and camera inspection to clear the toughest blockages quickly.

Why Choose Professional Drain Cleaning

Many homeowners resort to store-bought chemicals or DIY tools that provide temporary relief but can damage pipes over time. Our professional drain cleaning services are safe and effective, removing grease, hair, soap scum, and debris without harming your plumbing. We can also inspect the condition of your pipes with video cameras so you know if there are deeper issues that need attention.

Take Advantage of Reliable Water Heater Services

A functioning water heater is a must for daily comfort. When your water heater stops delivering hot water, leaks, or makes strange noises, it may be time for repair or replacement. Castlewood Plumbing technicians are experienced in diagnosing water heater problems and recommending the best solution.



We service all types of water heaters, including tank-style, tankless, gas, and electric models. If your unit is beyond repair, we can help you choose and install a new unit that meets your home’s hot water needs and energy-efficiency goals.

Act Now for Trusted Leak Detection and Repair

Hidden leaks can cause serious damage and lead to costly repairs if not caught early. A leak under a slab foundation, behind a wall, or in a crawl space can go unnoticed for months. Castlewood Plumbing uses state-of-the-art leak detection equipment to locate leaks quickly and accurately.



Once the source is identified, we provide efficient leak repair options. Our technicians take great care to minimize disruption and restore your plumbing system to full working condition. Prompt leak repair helps protect your home from water damage and mold growth.

Protect Your Property with Comprehensive Plumbing Maintenance

Regular plumbing maintenance can prevent unexpected breakdowns and extend the life of your system. Castlewood Plumbing offers maintenance plans tailored to your home or business needs.

Upgrade Your Water Quality with Treatment and Softener Systems

Hard water can leave mineral buildup in pipes, fixtures, and appliances. Over time this can reduce efficiency and lead to problems like spots on dishes or dry skin. Installing a water softener or treatment system can improve water quality throughout your home.



Castlewood Plumbing can assess your water quality and recommend the right solution. We install and service systems that remove contaminants and balance mineral content so your water is cleaner, safer, and better tasting.

Call Today for Gas Line Plumbing Services

Gas lines require careful handling and should only be serviced by trained professionals.
