Complete Pipe and Drain Inspection Services for Residential and Commercial Properties Across North Dallas and Collin County

Hidden plumbing problems can cost homeowners, buyers, sellers, investors, and commercial property owners thousands of dollars. A pipe may look fine from the outside, but inside the line there may be roots, bellies, offsets, standing water, broken pipe, cast iron deterioration, grease buildup, or major drainage defects.

At The Sewer Inspection Company, we provide complete pipe and drain inspection services across North Dallas, Plano, Frisco, Allen, McKinney, Richardson, Addison, Carrollton, Murphy, Wylie, Prosper, Celina, and Collin County. Our goal is simple: help you understand the true condition of the plumbing and sewer system before you buy, sell, repair, lease, or inherit a major underground problem.

Why Pipe and Drain Inspections Matter

Most people only think about their plumbing after something backs up, leaks, smells bad, or stops draining. The problem is that sewer and drain issues often develop long before anyone sees water on the floor or hears a toilet gurgle.

A complete pipe and drain inspection gives you visual evidence of the condition of the system. Instead of guessing, you can see what is happening inside the pipe.

As a Master Plumber, I have inspected homes and commercial properties where the surface looked perfect, but the underground sewer system told a different story. I have seen clean kitchens, remodeled bathrooms, new flooring, and fresh paint hiding old cast iron lines, poor slope, broken fittings, and sewer lines holding standing water.

Residential Pipe and Drain Inspections

Residential inspections are especially important before buying a home. A standard home inspection does not fully evaluate the underground sewer line. The home inspector may run water at fixtures, but that does not show the actual condition of the buried sewer pipe.

Our residential inspections may include:

• Sewer camera inspection
• Main drain inspection
• Cleanout inspection
• Cast iron pipe evaluation
• PVC sewer line evaluation
• Drainage performance testing
• Under-slab plumbing concerns
• Toilet, tub, shower, sink, and laundry drain observations
• Pipe locating when needed
• Video documentation and inspection report

In North Dallas and Collin County, many homes have aging sewer systems, foundation movement, clay soil conditions, previous repairs, or older cast iron piping. These conditions can create drainage problems that may not be obvious during a walkthrough.

Commercial Pipe and Drain Inspections

Commercial plumbing systems handle more volume, more fixtures, more tenants, and more daily use than a typical home. A drain problem in a commercial building can quickly become a business interruption.

We inspect drain and sewer systems for:

• Office buildings
• Retail centers
• Restaurants
• Medical offices
• Industrial buildings
• Warehouses
• Apartment buildings
• Mixed-use properties
• Investment properties
• Tenant finish-out spaces

A commercial inspection can help identify grease buildup, poor drainage, broken sewer lines, improperly connected piping, root intrusion, and recurring blockage points before they shut down a restroom, kitchen, or tenant space.

Common Problems We Find

A sewer camera inspection and drain evaluation can reveal issues that are impossible to see from above ground.

• Root Intrusion: Tree roots entering through joints, cracks, or separated pipe sections.
• Bellied Pipe: A low section of pipe that holds water and waste instead of draining properly.
• Offset Joints: Pipe sections that no longer line up correctly.
• Broken Pipe: Cracks, fractures, collapses, or missing pipe sections.
• Standing Water: Water sitting in the pipe due to poor slope, settlement, or obstruction.
• Cast Iron Deterioration: Rust, scale, channel rot, and rough pipe surfaces that restrict flow.
• Grease Buildup: Common in restaurants and commercial kitchens.
• Construction Debris: Dirt, mortar, plastic, tile grout, or building materials left inside the line.
• Improper Repairs: Bad connections, poor transitions, incorrect fittings, or incomplete replacement work.

Why This Matters Before Buying a Property

Buying a property without inspecting the sewer and drain system is a major risk. A sewer line repair under a yard, driveway, parking lot, or slab foundation can become one of the most expensive repairs a buyer faces after closing.

We have seen buyers discover problems after closing that could have been negotiated during the option period. We have also seen sellers avoid unnecessary repair demands by getting a second opinion and documenting the true condition of the line.

The right inspection can help:

• Protect buyers before closing
• Help sellers document the condition of the sewer line
• Give Realtors better information during negotiations
• Help investors evaluate repair risk
• Support commercial due diligence
• Prevent unnecessary repairs from bad diagnosis
