St. Petersburg's Full-Service Plumbers Since 1968

Homes across St. Petersburg face unique plumbing challenges driven by local conditions—aging pipe networks, accelerated corrosion from coastal salt air, and materials constantly expanded and worn down by intense heat. Over time, these environmental factors create silent failures: a water heater slowly rusting from the inside out, a main line drain losing speed week by week, aggressive root systems invading sewer lines, or heavy mineral deposits restricting your home’s water pressure. Left unchecked, these compounding issues eventually lead to sudden, costly system disruptions.

At McGill Plumbing & Water Treatment, Inc., our goal is to resolve plumbing emergencies quickly while actively preventing future ones. Serving Pinellas County and surrounding communities since 1968, we provide comprehensive residential and commercial plumbing services designed to keep your home running smoothly. Every job is handled by licensed, highly trained technicians who stay current with local Florida building codes and advanced plumbing technologies, ensuring long-lasting reliability for your property.

Plumbing Services Available in St. Petersburg

From routine residential repairs to complex commercial systems, McGill Plumbing handles every aspect of your property’s plumbing infrastructure. Our licensed technicians bring decades of local experience to every job, delivering targeted solutions designed for long-term performance and reliability across Pinellas County.

Our core service capabilities include:

Pipe Repair and Repiping

Discolored water, low water pressure, leaks, and rattling behind the walls are all signs your pipes need attention. If your plumbing system isn’t that old, you may just have a damaged section of piping that needs repair. An older plumbing system may have reached the end of its lifespan and require full replacement. We can handle both pipe repair and repiping. Our team will assess the entire system to identify the source of the problem and provide a fair recommendation on the work needed. 

Plumbing Maintenance

As with most systems in your home, routine maintenance can keep your plumbing system working better for longer. We provide plumbing maintenance services to keep small issues from becoming larger, more costly ones. Our licensed team can assess the condition of your system, notify you of any concerns, and perform approved work if needed. If we don’t spot any issues, we’ll tell you. We don’t push unnecessary work. 

Slab Leaks 

Detecting hidden slab leaks early protects both your home's foundation and your repair budget. A subtle leak beneath your concrete slab can quickly escalate—warping floors, ruining drywall, and leading to structural damage or mold. While slab leaks occur out of sight, key warning signs include unexplained water bill spikes, warm spots on your floor, lower water pressure, or musty odors. If you suspect an issue, our team steps in to perform precise, minimally invasive repairs (such as overhead repiping or targeted pipe rerouting) to resolve the leak and safeguard your St. Petersburg home.

Emergency Plumbing Services

Plumbing emergencies don't wait for business hours. McGill provides 24/7/365 emergency plumbing service throughout St. Petersburg. We respond to emergency plumbing calls without premium pricing for after-hours work. Fair rates apply whether you call at noon Tuesday or midnight Sunday. Dispatch coordinators can often troubleshoot over the phone and advise temporary steps to minimize damage before our truck arrives. 

St. Petersburg Sewer and Drain Services

Your drains work hard for your home every day, but you’re not likely to notice until there’s an issue. Backed-up pipes can often put your kitchen or bathroom out of order until the problem is fixed. We offer a variety of sewer and drain services to get things flowing again. 

Drain Cleaning

Grease, soap scum, mineral scale, hair, and food scraps can cause a clogged drain. When a blockage happens, you’ll likely notice one or more of the following:

• Slow-draining sinks and tubs

• Unpleasant odors coming from drains

• Gurgling sounds coming from the toilet, sink, or pipes

• Unexplained pools of water around your toilet, washing machine, sink, or shower

If you experience any of these or suspect a blockage, it’s important to act quickly to avoid a burst pipe or larger problem. Call on our team for professional drain cleaning. 

Drain Installation and Replacement

Drain lines are meant to be positioned at an incline leading away from your property to an underground sewer system or septic tank. If not installed properly, you’ll encounter some unpleasant issues down the road. We provide drain installation for new construction and drain replacement when systems aren’t functioning properly. 

Hydro Jetting

sewer repair and replacement is an advanced drain and sewer cleaning method that uses highly pressurized water to clear out blockages and clean pipe interiors. While snaking only impacts the center of the clog, hydro jetting scours pipe walls thoroughly to fully remove all stuck debris. This method is especially helpful for stubborn blockages where buildup has accumulated and hardened over time. 

Sewer Repair and Replacement

Sewer line damage can happen for many reasons: tree roots, ground shifting, blockages, poor installation, age and wear. When a sewer line fails, it will make itself known in a variety of unpleasant ways that need to be taken care of quickly. We provide sewer repair and replacement throughout St. Petersburg with same-day servicing in most cases. 

Water Heater Services for St. Petersburg

No hot water is no way to start the day. If you go to take a shower or wash dishes and the water is cold, it could be that you have a leaking tank, pilot light issue, valve problem, sediment buildup, or a variety of culprits we’re trained to identify. 

Water Heater Repair and Installation

We handle both water heater repair and installation. Whether your existing unit can be repaired or it's time to install a new water heater, our licensed plumbers will walk you through your options without pressure or unnecessary upselling. If a repair is the right solution, that's what we'll recommend. If replacement makes more sense, we'll explain why. 

Tankless Water Heaters

Many homeowners throughout St. Petersburg have switched to tankless water heaters in recent years to reduce standby energy loss. We provide tankless water heater installation and repair services for homes and businesses. We work with natural gas and electric systems. 

Thermal Expansion

Thermal expansion is a known problem for closed plumbing systems. Left unchecked, thermal expansion can contribute to leaks, premature equipment failure, and costly plumbing repairs. Our team can install a thermal expansion tank on the cold water supply line near your water heater to absorb excess pressure and reduce stress on the rest of your plumbing system. 

Water Treatment Services 

Many homes and businesses in Pinellas County deal with hard water. It causes stubborn scale buildup and hurts the longevity of water heaters and appliances. We can help combat it. 

Water Filtration Systems 

Municipal tap water can contain contaminants such as microbes, heavy metals, and chemicals that affect taste, smell, and overall quality. If you’re concerned about your water or have someone in your household with compromised immunity, installing a water filtration system is helpful. There are many options on the market: some for sinks, some for showers, some for the entire house. We can help you figure out which would work best for your home and goals. 

Water Softener Installation

You likely have hard water if:

• Your water smells or tastes strange

• Your dishes have spots when taken out of the dishwasher

• Your hands feel filmy after washing

• You have mineral stains in your sinks and showers

This just means you have a lot of calcium and magnesium in your water supply. While it’s not dangerous, it can affect the lifespan of water-using appliances, and it inhibits products like laundry detergent and shampoo from being able to do their job. 

The solution is to install a water softener to remove these excess properties from your water.
