Answers to Common Questions
View All FAQsWhat are the common causes of a sewer line backup?
The common causes of a sewer line backup are blockages, pipe damage, or slope problems that slow or stop wastewater flow. Tree-root intrusion is a leading trigger because roots seek moisture and invade pipe joints. Other backups come from grease or debris accumulations that narrow the pipe, or from structural issues that deform the line and catch waste. A camera often reveals the real issue fast, and we then clear or repair as needed. Our crews handle these issues across the Denver area, including Berkley homes, using CCTV inspections plus trenchless or traditional methods when appropriate.
Specific causes homeowners run into:
- Tree roots entering joints and creating root mats
- Bellies (sagging sections) that let debris settle and build up
- Collapsed, cracked, or misaligned pipe sections that snag waste
- Foreign objects, wipes, and grease buildup that harden and block flow
If sewage is backing up or drains are gurgling, stop water use and schedule a camera inspection before attempting any cleaning. <br/> Updated: 2026-05-11 <br/> Need help in Berkley, CO?

A sewer line cleanout is a capped access point to your main sewer pipe that lets a plumber quickly reach the line from ground level. It matters because it speeds camera inspections, hydro-jetting, and cabling, which helps clear clogs, reduce sewer odors, and avoid unnecessary digging. It also helps us pinpoint repairs or trenchless options faster for Denver and Thornton homes.
Quick signs you’ll use the cleanout:
- Recurring clogs or backups
- Strong sewer odors
- Slow drains across multiple fixtures

A sewer line inspection for homeowners uses a CCTV camera to view the inside of your sewer pipe and document its condition. The goal is to pinpoint blockages, cracks, roots, or misaligned sections so repairs are targeted and digging is avoided unless needed. Our plumbers feed a camera through the line, use the video to map the pipe’s path, and use that information to choose the least invasive fix, from cleaning to trenchless repair or replacement. We perform this same diagnostic‑first process across the Denver area, including Berkley, so you get clear answers before any work begins.
Typical steps and outcomes include:
- Access a cleanout and run a video camera while recording.
- Locate and mark problem spots and depths from the surface.
- Identify causes like buildup, roots, cracks, or sags.
- Recommend next steps: cleaning/jetting, spot repair, CIPP lining, pipe bursting, or excavation.
Avoid using drain chemicals before an inspection so the tech can work safely and the camera can see clearly. <br/> Updated: 2026-06-01 <br/> Need help in Berkley, CO? Call (720) 994-7055 or book online. He and his teammate were on time, efficient and extremely helpful. — Kathrine G.

Most homeowners should schedule a sewer camera inspection when symptoms appear or before big decisions. Book one if you have recurring clogs, slow drains, sewer odors, or before buying a home in Denver. Inspections are also smart after known tree-root issues or on older clay/cast-iron lines. We start with a CCTV camera to find the exact problem before any cleaning, repair, or replacement. Many customers pair inspections with annual sewer cleaning to prevent backups. <br/> Updated: 2025-12-21 00:00:00 <br/> Need help in Thornton, CO? Call (720) 994-7055 or book online.

Professional main sewer line unclogging is priced after an on-site camera inspection. In Denver and Thornton, we start with a CCTV inspection, then clear with drain cabling or hydro-jetting. Final cost depends on access, line length, severity, and whether roots or a damaged pipe need spot repair or trenchless work. Technicians provide transparent, upfront quotes before work. Ask about current $30–$50 off sewer repair coupons in Arvada, Parker, Lakewood, Wheat Ridge, Longmont, and Commerce City.

Main sewer line cleaning cost depends on what’s clogging the pipe and the method used. We start with a CCTV camera inspection, then give an upfront price before any work. Pricing varies between drain cabling for soft blockages and hydro-jetting for heavy buildup or roots. Many jobs can be cleaned the same visit after the inspection in Denver and nearby cities.
What affects cost:
- Camera findings (roots, grease, collapse)
- Cleaning method (cabling vs. hydro-jetting)
- Access and length of the line
- Need for spot repair vs. cleaning only

Trenchless sewer line replacement does not have a one-size price; Brothers provides firm pricing after a camera inspection because cost varies by pipe condition, length, access, and the trenchless method selected. The biggest driver is whether your line can be restored with CIPP lining or needs pipe bursting, which we determine by inserting a CCTV camera to pinpoint damage and connections. Our crews complete trenchless projects across the Denver metro and regularly serve homes in Castle Rock. If a small excavation is needed, we limit the dig and restore surfaces, and that scope is reflected in the final number. You’ll see transparent, itemized options, and many issues qualify for targeted point repairs instead of full replacement. Current site coupons often provide $30–$50 off eligible sewer work, subject to offer terms.
Key factors that change trenchless price:
- Pipe length/diameter and depth
- Method: CIPP lining vs pipe bursting vs point liner
- Access pits and obstacles like landscaping or concrete
- Pre-work needs like hydro-jetting to clear roots or debris
Schedule a CCTV inspection early if you notice recurring clogs or sewer odor so we can price the right fix before damage spreads. <br/> Updated: 2026-03-30 <br/> Need help in Castle Rock, CO?
