Plumbing Services for Chatham Homeowners & Businesses

We handle the full range of residential and small-business plumbing, from routine repairs to the kind of emergencies that happen on the worst possible night. Our trucks carry what we need to complete most jobs on the first visit, so you’re not waiting on a parts order to get back to normal.

Drain Cleaning & Sewer Service

Slow drains and sewer backups rarely fix themselves. We clean drains throughout the entire home or business, including kitchen sinks, bathroom drains, and main sewer lines. After-hours sewer and drain cleaning is available when the situation can’t wait until morning.

Water Heater Repair & Replacement

We service and repair both tank and tankless water heaters, gas and electric. Same-day water heater service is available for units that have stopped working or are actively leaking. Tank-style gas water heaters are the most common setup in central Illinois homes, and we handle repairs, service, and full replacement when the unit has run its course.

Frozen & Burst Pipe Repair

Illinois winters create real freeze-up risk, and a burst pipe can flood a home quickly once it thaws. We carry pipe-thawing equipment and can often restore a frozen line without opening walls or damaging finished surfaces. For pipes that have already burst, 24/7 emergency repair is available.

Sump Pump Service & Installation

Basement flooding is a recurring concern throughout Sangamon County, especially during spring thaws and summer storms. We service, repair, and install sump pumps and battery backup systems to help keep your basement dry when the weather turns. Annual system checks help confirm the pump can work when it’s needed most.

Toilet Repair & Installation

Running toilets, slow refills, chronic clogs, and weak or double-flush problems are all jobs we handle. We also install new toilets when replacement makes more sense than another repair.

Fixture & Remodeling Plumbing

We install and repair bathroom and kitchen fixtures and provide plumbing support for home remodeling projects, keeping the work on schedule and up to code.

Heating, Cooling & Air Quality Services in Chatham

Because we handle both plumbing and HVAC under one roof, you don’t need a separate company when the furnace needs attention or the AC stops cooling. Illinois winters push heating systems hard, and hot summers demand reliable air conditioning. We’re equipped for both.

Our HVAC services include:

• Air conditioning repair, service, and installation for central AC systems, heat pumps, and ductless mini-splits
• 24/7 emergency AC service during peak cooling season
• Gas furnace maintenance, repair, and maintenance agreements
• Heating and cooling accessories: electronic, electrostatic, and media air filters; UV lights; humidifiers and dehumidifiers
• Indoor air quality system installation and service for homes and businesses

All HVAC installation and service work is performed by EPA-certified, licensed technicians. Our fully stocked service vehicles mean cooling and heating repairs rarely require a second trip.

The Priority Maintenance Club

Our HVAC and Plumbing Priority Maintenance Club is designed for homeowners who want consistent protection without the hassle of scheduling it themselves. Members receive priority same-day scheduling, a 10% discount on all services, and three free safety inspections each year: two HVAC inspections and one plumbing inspection. Preventive attention on these systems is a reliable way to help avoid after-hours emergencies and extend the life of the equipment you depend on.

Same-day service is our standard, and 24/7 emergency service is available when you can’t wait. Every job we perform is backed by our 100% satisfaction guarantee. Call Mike Williams Plumbing, Heating, Air Conditioning & Sewer at (217) 673-0758 to schedule plumbing or HVAC service in Chatham, IL.
