When you partner with Thorough Plumbing, you're choosing a company that goes the extra mile to protect your property, time, and peace of mind.
The Importance of Proper Drain Installation
Your drainage system is the unsung hero of your plumbing infrastructure. It safely and efficiently removes wastewater from your home, protecting you from backups, water damage, mold growth, and costly repairs.
Faulty drain installations—often performed by unlicensed handymen or rushed contractors—can result in misaligned piping, frequent clogs, poor water flow, and sewer line issues. These are not just inconvenient—they’re potentially hazardous to your health and home structure.
At Thorough Plumbing, we understand the science behind drainage and the precision it requires. Our technicians are thoroughly trained to assess pipe gradients, material types, venting, code compliance, and the right fittings to ensure smooth operation from day one.

Are you building a home or upgrading your bathroom or kitchen? We offer comprehensive drain installation services tailored to your property layout, local plumbing codes, and long-term efficiency. From kitchen sinks to walk-in showers and basement floor drains, our team ensures proper placement, sealing, and slope for uninterrupted flow.
We work closely with homeowners, builders, and remodelers throughout Allen and nearby neighborhoods to install drain systems that are both functional and future-proof. You can count on us for clear communication, fair pricing, and zero surprises.
Replacing Outdated or Failing Drain Lines
Drain lines age. Whether from corrosion, root intrusion, shifting soil, or wear-and-tear, many Allen homes—especially older properties—have outdated galvanized or cast iron pipes that no longer serve efficiently.
If you're experiencing:
- Persistent drain clogs
- Water pooling around fixtures
- Foul odors from sink or shower drains
- Gurgling sounds after flushing
- Slow draining water
…it might be time to consider a new drain installation.
Our skilled plumbers will perform a detailed inspection and offer solutions that fit your home, budget, and timeline. We only use top-rated materials and cutting-edge tools to ensure a seamless upgrade.
