Why Poly-B is a Major Concern in Calgary Townhouses
If your townhouse in Calgary still has Poly B piping, you’re sitting on a ticking time bomb. While Polybutylene plumbing was once a common choice in multi-unit builds from the 1980s through the 1990s, it’s now one of the most notorious causes of water damage in Canadian homes—especially in townhouses with shared walls and interconnected plumbing systems. Add Calgary’s unique freeze-thaw cycles and increasingly strict insurance and resale standards, and you’ve got a system that urgently needs replacement.
How Calgary’s Climate Impacts Poly-B Failures
Calgary’s cold winters and sharp temperature shifts contribute to thermal stress on Poly-B (polybutylene) piping. Over time, this leads to microfractures and weakening of pipe joints, especially where metal fittings were used during initial installations. Calgary’s hard water also catalyzes internal pipe scaling, further reducing plumbing lifespan.
If you are a Calgary homeowner dealing with Poly B pipes, you are not alone — thousands of homes in the city were built with this outdated plumbing. Urban Piping specializes in Poly B Replacement Calgary and has helped over 3,000 homeowners make the switch. Ready to get started? Call (403) 988-3801 for your free estimate.
Over 10,000 Calgary homes still have Poly B pipes – and townhouses are especially at risk.
Why Townhomes Are at Higher Risk for Shared Plumbing Issues
Poly B failures in one unit can cascade across multiple townhomes. That’s because linked domestic water systems in many Calgary townhouse complexes create a scenario where a single rupture might affect neighbours. This is especially problematic during high-usage hours or in winter when water lines are under peak pressure.
Insurance Complications for Poly-B Pipes in Multi-Residential Buildings
Some insurers now refuse to renew home policies or mandate higher premiums for properties with active Poly B systems—townhouses included. For shared ownership and condo corporations, this can result in escalating building-wide costs. If your home is part of a townhouse community, confirming pipe type is now not just prudent—it’s a financial safeguard.

How to Identify Poly B Plumbing in Your Townhome
A professional from Urban Piping demonstrates poly b townhouse replacement maintenance steps in Calgary and surrounding areas.
If your townhouse was built between 1985 and 1997 in Calgary, there’s a high chance it contains Poly B pipes. Spotting these outdated systems can be easier than you think—if you know what to look for. Early identification allows you to budget, plan, and avoid sudden damage from leaks and pipe bursts.
Physical Features of Grey Poly B Piping
Polybutylene pipes are typically grey, flexible, and about half an inch to one inch in diameter. They often have printed markings like “PB2110” stamped along the side. The pipes can be found snaking between fixtures or bending around corners with flexible elbows, often connected with metal or plastic crimp rings.
Poly-B pipes are usually grey and flexible with markings like ‘PB2110’.
Common Locations in Calgary Townhomes
Look under kitchen and bathroom sinks, around the water heater, in unfinished basement ceilings, or in the utility room. In some townhouses, they may be tucked inside access panels behind toilets or appliances. Urban Piping professionals are trained to conduct a full system trace to confirm Poly B status even in hard-to-reach areas.
When Was Your Townhouse Built? Key Indicators from 1985–1997
Poly B was heavily marketed for use in residential and multi-family developments during this time. Calgary’s robust townhouse developments from these years are now aging into the failure window, making inspection extremely important for homes built before 1998.
Most Poly B plumbing in Calgary homes was installed between 1985 and 1997.

The Cost and Risk of Ignoring Poly B Pipes
Urban Piping highlights the risks and potential costs of poly b pipe leaks in Calgary townhouses.
Delaying your Poly B townhouse replacement can cost more than just money—it can cost you your home’s safety and insurability. While it may seem harmless at first glance, aging Poly B plumbing is one of the leading causes of water damage, especially in Calgary’s older townhomes. Left untouched, these pipes can lead to everything from soaring insurance premiums to structural damage that ripples through your multi-unit block.
What Happens When Poly B Fails (Leaks, Floods, Water Damage)
Once cracked or ruptured, Poly B piping often results in rapid, undetectable leaks behind drywall, in ceiling cavities, or beneath flooring. These leaks can create mold growth, drywall collapse, and damage to electrical systems. Costs balloon quickly when full-room demo and water mitigation are required.
One townhouse flood from failed Poly B can cause $50,000+ in repairs.
Potential Damages in Shared-Townhouse Infrastructure
Because of the shared plumbing frameworks in many Calgary townhouses, a single pipe burst can create cascading liabilities. Urban Piping technicians have seen cases where townhouse leaks migrate into adjacent units, triggering strata claims and neighbor disputes.
Hidden Long-Term Costs of Waiting (Insurance, Resale Value)
Ongoing possession of Poly B systems may signal “red flag property” to insurers and buyers alike. Many policy providers now require full replacement before offering home insurance, and some mortgage lenders are also scrutinizing for plumbing material before renewals. Replacing with PEX piping or copper is more than an upgrade—it safeguards property equity.
Replacing Poly B can increase resale potential by up to 10% in competitive Calgary markets.
Invest in peace of mind—replace early and protect your home’s value.
What to Expect During a Poly B Replacement in Calgary Townhouses
Replacing polybutylene (Poly B) plumbing in your Calgary townhouse isn’t just about swapping out old pipes — it’s about restoring confidence, code compliance, and long-term home health. Homeowners in Calgary, Edmonton, and the Vancouver area trust seasoned professionals to perform thorough, safe, and efficient repiping services with minimal disruption to daily life. Here’s exactly what to expect from the moment you schedule your estimate to the final walkthrough.
Inspection and quote process
Every Poly B replacement starts with a full plumbing inspection. An experienced Urban Piping technician will assess your townhouse’s layout, verify pipe accessibility, and take measurements. Because townhomes often share walls or ceilings, special attention is given to shared service lines and shut-offs. The estimate you receive will be detailed and transparent—with no surprise charges.
“Townhouse repiping typically takes 3–5 days, depending on layout and access.”
Inside access: how we repipe without major disruption
Urban Piping uses a systematic approach to minimize disturbance. Technicians cut small, strategic access points near fixtures like sinks, tubs, and laundry valves. These areas allow us to cleanly remove Poly B plumbing and install new cross-linked polyethylene (PEX) without major wall or floor removal. Dust barriers and floor protection are always used during the process.
Drywall and finishing included in full restoration
After the PEX piping is professionally installed and pressure-tested, our finishing crew gets to work. Restoration includes drywall repair, texturing, and painting to match your original walls. This full-circle service ensures your home looks the same — or better — than before we began.
Urban Piping provides complete drywall and paint restoration after every replacement – leaving no trace of the job.
Start your townhouse repipe the right way — with professional guidance and a clutter-free result you can trust.
Calgary Codes, Permits, and Choosing the Right Contractor
If you’re planning a Poly B replacement in Calgary, understanding local building codes and hiring a certified contractor is essential—especially when repiping multi-unit dwellings like townhouses. Failing to follow municipal procedures can lead to refused permits, insurance challenges, or improper plumbing that may fail years down the road.
What permits are needed for townhouse repiping?
In Calgary, repiping a townhouse unit requires a Plumbing Permit from the city. For attached townhomes, strata or condo board approval may also be necessary. The permit ensures compliance with the building code, including anti-syphon requirements, fixture counts, and appropriate material use (such as replacement with PEX Class A).
Only city-licensed plumbers can pull the correct permits for Calgary townhouse repiping.
How to verify your plumber is licensed in Calgary
Qualified plumbing contractors in Calgary must hold a valid city contractor ID number. Ask to see this along with proof of insurance and WCB coverage. You can also search the City of Calgary’s public database to confirm license status. Reliable contractors will always be happy to provide documentation upfront.
Urban Piping is fully certified and experienced with multi-unit compliance.
Red flags when hiring someone for Poly B replacement
Be cautious of unlicensed handymen or “too good to be true” quotes. Poly B replacements involve complex steps beyond basic plumbing, including structural access, material selection, pressure-testing, and drywall restoration. Avoid any contractor unwilling to address permits, or who lacks verifiable townhouse experience.
Choose peace of mind by working with Calgary-based plumbers who understand both code—and your concerns.
Post-Replacement Maintenance Tips to Keep Your Pipes Healthy
Now that your Calgary townhouse is protected by new PEX plumbing, follow these expert maintenance tips to ensure long-term performance and leak-free living. While PEX piping is durable and flexible, smart homeowners know that simple seasonal checks keep things flowing smoothly year after year.
How to test your new pipes seasonally
Each spring and fall, visually inspect visible plumbing areas (basements, under-sink cabinets, laundry rooms) for drips or corrosion at fittings. Turn on and off fixtures to listen for abnormal hissing or water hammer. Watch for changes in water pressure or colour—both can indicate post-install adjustments are needed.
Preventing pressure surges and future leaks
Calgary homes often suffer from high municipal water pressure. Install a pressure-reducing valve (PRV) to keep levels under 60 psi. Sudden pressure spikes or quick shutoffs from appliances can stress even new piping. Consider adding water hammer arrestors to high-risk fixtures like washers or dishwashers.
Routine inspections and when to call your plumber
Schedule annual inspections with your plumbing contractor, especially during the first year. These check-ins allow for early detection of valve wear, insulation gaps, or potential freezing concerns in colder zones. If any strange noises or leaks occur—even small ones—call your licensed Calgary plumber right away.
We recommend an annual plumbing check-up, especially after the first winter post-installation.
