What Our Clients Say About Us
Always prompt and professional. The work is done quick and properly. Never have anything but good to say and the team at Liquid Copper.
Alden Mclellan
I am a property manager and have used many plumbing companies before I found Liquid Copper. There hasn't been a job big or small that wasn't handled with expediency and professionalism. Pricing has always been more than appropriate and every question I have had about every job was answered with insight and collaboration. These guys are good to either point them in the direction of the problem and wait for the bill or ask their advice and make informed decisions. I wouldn't recommend anyone else.
Thanks Rob, it was been and continues to be a pleasure working with your company.

Frequently Asked Questions
Do plumbing renovations require permits in Ottawa?
In many cases, yes.
Plumbing permits are typically required in Ottawa when:
- Installing new rough-ins
- Relocating plumbing fixtures
- Replacing underground sewer or water lines
- Installing backwater valves
- Performing major system alterations
Minor fixture replacements, such as swapping a faucet or toilet in the same location, usually do not require permits.
Who pulls the plumbing permit on renovation projects?
This depends on the project structure.
- In some builds, the general contractor pulls the overall permit.
- In other cases, the licensed plumbing contractor pulls the plumbing-specific permit.
What matters is clarity before work begins. We confirm permit responsibility early to avoid inspection conflicts or delays.
If your company prefers to manage permits internally, we coordinate documentation and inspection scheduling accordingly.
How long does a plumbing rough-in take in Ottawa?
Timelines depend on scope and site readiness.
Typical timelines:
Standard bathroom rough-in: 1 to 2 days
Kitchen rough-in: 1 day
Full custom home rough-in: several days to over a week depending on size and complexity
Major renovation with rerouting and structural modifications: variable
Delays usually happen because:
- Framing is not complete
- Drawings are unclear
- Structural changes occur mid-project
- Other trades are behind schedule
We do not start rough-ins until the site is ready. Starting too early creates rework and callbacks.
When should plumbing rough-ins be scheduled?
Rough-ins should occur:
- After framing is complete
- Before insulation and drywall
- When final fixture locations are confirmed
If layouts are still shifting, rough-in delays are cheaper than redoing finished work.
We coordinate closely with site supervisors to prevent overlap with electrical and HVAC teams.
What inspections are required after plumbing rough-ins in Ottawa?
Most permitted plumbing rough-ins require inspection before walls are closed.
Inspections typically verify:
- Proper venting
- Correct slope on drainage lines
- Code-compliant pipe sizing
- Pressure testing on supply lines
Closing walls before inspection approval can result in costly reopening. We schedule and prepare for inspection to reduce risk.
How long does underground plumbing replacement take?
For sewer or water line replacement in Ottawa:
- Standard residential sewer replacement: 1 to 3 days
- Complex excavation or deep lines: longer depending on depth and access
Factors affecting timeline:
- Soil conditions
- Access to property
- Municipal requirements
- Weather conditions
Ottawa’s frost depth and older infrastructure can complicate underground work. Proper planning prevents mid-project surprises.
Do you coordinate with excavation teams and other trades?
Yes.
Underground replacements and large-scale renovations require coordination with:
- Excavation contractors
- Concrete teams
- Framers
- HVAC and electrical trades
Miscommunication between trades is one of the biggest causes of construction delays. We align scheduling early to prevent conflict.
Can you handle high-end fixture installations for luxury builds?
Yes.
High-end bathrooms and kitchens often involve:
- Wall-mounted fixtures
- Custom shower systems
- Specialty valves
- Integrated smart plumbing features
These require precise rough-in measurements. Minor alignment errors become major finishing problems.
We confirm specifications before rough-in to protect your finish schedule.
What causes plumbing delays on renovation projects?
Common causes include:
- Incomplete drawings
- Structural changes after rough-in
- Late fixture selection
- Permit confusion
- Inspection scheduling delays
If timelines are unrealistic, corners get cut. That leads to failed inspections or callbacks. We prefer realistic scheduling over rushed work that damages your reputation.
Do you offer long-term subcontractor partnerships in Ottawa?
Yes.
We work with renovation companies and custom builders looking for:
- Consistent scheduling
- Clear communication
- Code-compliant installations
- Reduced callback rates
