What Our Plumbing Services Include
Every property has different needs. However, these are the services clients request most often.
Rough-In Plumbing
We lay out new pipes, drain stacks and water supply lines for new builds, additions and renovations. Because we plan early, the finished fixtures fit exactly where you want them.
Water Line & Pipe Replacement

Drain Installation & Repair
We position drain lines precisely and repair damaged sections. Therefore, water drains smoothly, clogs clear and leaks stop.
Kitchen Plumbing
We install sinks and high-efficiency faucets, and we connect disposals, dishwashers and ice makers. Moreover, we check every connection for leaks before we finish.
Bathroom Plumbing
We handle vanities, walk-in showers, freestanding tubs, low-flow toilets and custom spa fixtures. In addition, we rough in the plumbing for new bathrooms.
Basement & Laundry Room Plumbing
We plan dedicated plumbing for basement apartments, secondary suites, wet bars, washing machines and laundry tubs. For example, we can add a new bathroom below grade.
Tankless Water Heaters
We install and upgrade on-demand systems that save space. Besides providing continuous hot water, they can lower your energy bills.
Hot Water Tank Installation
We set up and replace traditional gas or electric storage tanks. Therefore, you get reliable hot water without a long wait.
Sump Pump Installation
We install and maintain primary and battery-backup sump pumps. As a result, your basement stays dry during heavy weather, even if the power fails.
Backwater Valve Installation
We install backflow prevention valves that guard lower levels against municipal sewer backups. In addition, some municipalities offer subsidies, so check your city’s program.
Signs Your Property Needs Plumbing Work
Plumbing problems rarely fix themselves. However, early action keeps repairs small and affordable.
Low Pressure or Discoloured Water
Weak flow or brown water often points to corroded pipes. Therefore, you should have a plumber inspect the lines soon.
Slow Drains & Gurgling Sounds
Repeated clogs and strange noises suggest a blocked or poorly vented drain. As a result, a camera inspection or repair may help.
Damp Basements & Past Backups
Moisture, musty smells or earlier sewer backups signal a risk. For that reason, a sump pump or backwater valve is worth considering.
Aging Pipes & Old Water Heaters
Galvanized steel and other older pipes wear out over time, and most tanks last only a limited number of years. Consequently, planned replacement costs less than an emergency repair.
How We Run a Plumbing Project
Good plumbing follows a clear process. Here is how we keep every project organized.
1. Consultation & Inspection
We visit the property, inspect your existing system and discuss your goals. Then we explain what the project needs.
2. Design & Material Selection
First, we plan pipe routes, fixtures and venting. Next, we choose materials that suit your budget and your building.
3. Quote & Scheduling
You receive a written scope, pricing and timeline. Moreover, we plan water shutoffs carefully to limit disruption to your day.
4. Installation, Permits & Inspection
We install the system to the Ontario Building Code. In addition, we handle plumbing permits and book inspections where they apply.
5. Testing & Final Walkthrough
We pressure-test lines and check every connection. Finally, we walk you through the work and clean up the site.
What Affects the Cost of Plumbing Services?
No two plumbing projects cost the same. Knowing why can help you plan with confidence.
Scope & Complexity
A faucet swap costs far less than a repipe or a new bathroom. Also, relocating fixtures adds time and materials.
Pipe Material & Condition
Older systems often need extra repair work. As a result, a thorough inspection helps us give you an accurate quote.
Access & Finishes
Finished walls and floors take more time to open and repair. However, planning plumbing during a renovation reduces that cost.
Fixtures & Equipment
Premium fixtures, tankless systems and backup pumps add to the total. Therefore, we help you decide where the upgrades matter most.
Why Choose Proventa Construction for Your Plumbing Project?
Frequently Asked Questions: Plumbing Services
Straight answers to the questions clients ask us most often.
Cost, Permits & Timeline
How much do plumbing services cost in Ontario?
The price depends on the scope, the age of your pipes and the fixtures you choose. For example, a faucet replacement costs far less than a repipe. After we inspect your property, we give you a clear written estimate.
Do I need a permit for plumbing work in Ontario?
New installations and many alterations need a municipal plumbing permit, and an inspector reviews the work. However, minor repairs such as replacing a faucet usually do not. We check what applies to your project and handle the process for you.
How long does a plumbing project take?
A small repair may take a few hours. A new bathroom rough-in or a repipe takes longer, and the schedule depends on access and inspections. We give you a timeline before we start.
Pipes, Water Heaters & Fixtures
When should I replace my home’s pipes?
Consider replacement if you see frequent leaks, low pressure, discoloured water or older materials such as galvanized steel. In addition, some insurers ask owners to replace certain older pipe types. We inspect the system and explain your options.
Is a tankless water heater better than a tank?
It depends on your household. Tankless units save space and provide continuous hot water, whereas tanks usually cost less up front. Moreover, a tankless system may need gas line or venting upgrades. We compare both and help you choose.
Can you add a bathroom or plumbing to my basement?
Often, yes. First, we check drain depth, floor conditions and local requirements. Then we design the plumbing, which may include a pump system if gravity drainage is not possible.
Flood Protection & Emergencies
What is the difference between a sump pump and a backwater valve?
A sump pump removes groundwater that collects around your foundation. A backwater valve, on the other hand, stops sewage from flowing back into your home. Because they solve different problems, many homes benefit from both.
Do I need a battery backup for my sump pump?
We recommend one. Heavy storms often cause power outages, which is exactly when a basement is most at risk. Therefore, a battery backup keeps the pump running when you need it most.
What should I do if I find a leak?
First, shut off the water at the fixture valve or the main shutoff. Then move belongings away from the water and contact a plumber. Quick action limits damage, so do not wait.
