Mount Royal Plumbers Calgary — Heritage + Rebuild + Hydronic Radiant

Most likely original galvanized supply lines (1910s-1940s era) closing off with mineral scale, cast iron drain stacks with joints separating + pinhole leaks at horizontal runs, and clay sewer lateral to the city main. Walls are typically plaster + lath. We can diagnose without destruction using infrared imaging + acoustic detection — we'll tell you what's behind the wall before recommending any tear-out.

Almost always galvanized supply lines closing off with mineral scale. Heat accelerates scaling, so hot-side pressure typically drops worse than cold. Replacement to copper or PEX-A restores flow. Often phased over major renovation cycles to coordinate with broader scope. We assess + quote in writing — no rip-and-replace by default.

Yes — Jason's specialty. 20+ years on hydronic systems including multi-zone in-floor radiant, manifold sets (Caleffi, Uponor, Viega), zone valve service, balancing valve adjustment, snowmelt loops, and the combi or system boilers driving them. Brand-agnostic on Viessmann, Triangle Tube, IBC, Navien, Lochinvar, NTI. See boiler not working Calgary for diagnostic scope.

Almost certainly DHW heat exchanger scaling. Combi boilers have two heat exchangers — one for space heating, one for domestic hot water. The DHW exchanger has narrow internal passages where Calgary's hard water (150-200 mg/L) scales aggressively. Descaling restores output in most cases; severely scaled exchangers sometimes need replacement. Annual descaling + softener pairing prevents recurrence.

Most common cause: root intrusion in the clay sewer lateral. Mount Royal's mature street trees have established root systems that find joint cracks in 90-year-old clay laterals. Camera inspection identifies the location + severity. Hydro-jet or mechanical cutting clears short-term; trenchless lining or spot repair for permanent fix. We don't trench up the front lawn unless there's no alternative.

Yes — these are the brands we install most in Mount Royal. Pressure-balance valves, thermostatic shower systems, body sprays + rainfall heads, freestanding tub fillers, custom drains. Brand-specific cartridge knowledge matters — generic plumbing experience isn't enough on premium fixture lines. We carry parts catalogues + order direct from authorized distributors.

Strongly recommended. Calgary's hard water (150-200 mg/L) is the same hard supply across the whole city. Premium fixture cartridges, dishwasher valves, washing machine valves, combi boiler DHW heat exchangers all wear faster without a softener. Single softener at the main entry protects the whole house — particularly important when the downstream fixtures are premium-grade. See water softener Calgary.

Yes — we handle GC coordination routinely on Mount Royal projects. Confirmed schedule windows, written quotes formatted for GC scope review, inspection coordination, and integration with broader trade schedules (framing, electrical, HVAC, drywall). Single point of contact, scheduled communication.

Same-day for emergencies — burst pipes, no hot water, no heat, sewer backup. Real person on the phone, we'll confirm a window before the truck rolls. Mount Royal is on our regular dispatch radius; SW dispatch via 14th Street or Crowchild makes the run fast.

Same crew works Altadore, Marda Loop, Killarney, Bel-Aire, Signal Hill, Aspen Woods, West Springs, and the broader SW Calgary. Heritage + rebuild + hydronic expertise translates across all of them.
