Why Choosing the Right Contractor Matters
Sewer line replacement is one of the biggest repairs your home can face. It's disruptive, and it's not cheap. Get it wrong, and you could be digging up the same yard twice.
Poor workmanship doesn't just mean a repeat clog. It can lead to yard damage, foundation issues, or a sewer line that fails again within a year or two. Many older Westminster homes still have original clay pipe, and that pipe wears out over time.
Choosing the right contractor the first time saves you money in the long run. It also saves you the headache of a torn-up yard for a second round of work. The checklist below will help you get it right from the start.
Check These Credentials Before Hiring
Before you let anyone touch your sewer line, check their paperwork. This part takes ten minutes and can save you from a costly mistake.
- Colorado DORA plumbing license. Every plumber working in Colorado needs an active license through the state. Ask for the license number and look it up yourself before hiring.
- General liability insurance and worker's comp. This protects your property and you, in case anything goes wrong on the job.
- Local business registration. A real, established company will have proper registration and won't dodge the question.
- Bonding for excavation work. Larger digging jobs often call for a bond. Ask if the company carries one.
As a family-owned business, we hold all required Colorado and local licenses and carry full insurance coverage. Our crew includes certified Master Plumbers who keep current with code updates and manufacturer certifications, so every sewer line job is done right the first time.
Questions to Ask Before You Sign a Contract
A good contractor won't dodge your questions. Here's a short script to run through before you sign anything.
- Do you offer trenchless replacement, or only traditional dig?
- Can I get a written, itemized estimate before work starts?
- What warranty do you offer on labor and materials?
- Who handles the permits and city inspections?
- Can you share references or recent jobs you've done nearby?
Write down the answers. If a contractor hesitates on any of these, that's worth noting. A company confident in its work will answer fast and in detail.
Trenchless vs. Traditional Sewer Line Replacement
Once you know a contractor is licensed, it helps to understand the two ways a sewer line actually gets replaced. That way, you can judge their recommendation instead of just taking their word for it.
Trenchless replacement uses pipe bursting or pipe lining to replace the line through small access points. Your yard stays mostly intact, and the job usually moves faster.
Traditional replacement means digging a full trench along the pipe's path. It can cost less in some cases, but it tears up more of your yard and takes longer to finish.
| Method | Yard Disruption | Typical Timeline |
|---|---|---|
| Trenchless | Minimal | Faster |
| Traditional dig | Extensive | Longer |
Not every yard qualifies for trenchless work. Soil type, pipe depth, and existing damage all play a role. A good contractor will assess your property on-site and tell you honestly which method fits, not just push whichever one is more profitable for them.

What Sewer Line Replacement Costs in Westminster (And Why Estimates Vary)
With the right questions asked and methods understood, here's what to expect when it comes to cost. Every yard is different, so prices vary from home to home.
A few things drive the price up or down:
- How deep the pipe sits underground
- The total length of pipe that needs replacing
- How easy or hard the pipe is to access
- Whether trenchless or traditional dig is used
Be cautious of a quote that comes in far below everyone else's. A lowball number is often a sign that something gets left out later, or the work gets rushed. The best move is to get a detailed, in-person estimate rather than a quote over the phone. A contractor who won't walk your property before quoting a price is one to think twice about.
Red Flags That Signal You Should Walk Away
By now you know what to look for. It's just as important to know what should send you running the other way.
- They won't give you a license number when asked
- They demand full payment upfront
- They have no local Westminster reviews or Google Business Profile
- They use pressure tactics like "today only" pricing
- They only give verbal estimates, never written ones
One thing we see constantly on Westminster calls is homeowners who got burned by a verbal-only quote that ballooned once the digging started. A written, itemized estimate protects you from that surprise.
If a contractor shows even one of these red flags, it's worth getting a second opinion. Your sewer line is too big an investment to leave to chance.
