Montgomery Plumbers Calgary — Post-War Stock, Infill + Rentals
Montgomery was its own town until 1963, and the housing still shows it: modest 1940s and 1950s bungalows on generous lots, now sitting between a steady stream of infill rebuilds and one of the densest rental markets in northwest Calgary. Three very different kinds of plumbing call, on the same streets.
The original stock here is post-war and small, which means early copper supply mixed with galvanized runs, cast-iron drain stacks, and heating plant that has often been replaced once and is now due again. None of it is exotic — it's just old, and it needs someone who knows what era they're looking at before they start cutting.
The second Montgomery is the rebuild. Proximity to Foothills Medical Centre, the Alberta Children's Hospital and the University has made this one of the most actively redeveloped parts of the northwest, and the infills going up run modern PEX, high-efficiency heating, and sometimes hydronic radiant. Same crew handles both.
The third is rental. A large share of Montgomery is tenanted, and landlords need something different from homeowners — fast turnarounds between tenants, a straight answer on repair versus replace, and work that will not generate a callback at 11pm. Call 587-834-3668 and a real person answers.

What we get called for most in Montgomery
Three housing stories on the same streets — the post-war originals, the infills replacing them, and the rentals in between.
Rental turnover plumbing
Between tenants is when the deferred stuff surfaces: a toilet that has been running for months, a tap nobody mentioned, a water heater on borrowed time. We work to a date, give you a written scope, and flag what will fail next so you can decide whether to do it now while the unit is empty or budget for it later.
Mixed galvanized and copper supply
Post-war homes here often have galvanized runs left in place alongside later copper. Galvanized closes off internally with mineral scale, and the tell is hot-side pressure dropping noticeably worse than cold. Replacement through accessible runs is straightforward; we map what's actually there before quoting rather than assuming.
Cast-iron drain stack repair
Cast iron from this era fails at the joints and through pinhole rust along horizontal runs. The symptom is usually slow drainage with a damp patch appearing on a basement ceiling. Camera inspection establishes how far the deterioration runs so replacement is scoped to what's failed.
Furnace and water heater replacement
A lot of Montgomery equipment was replaced once in the 80s or 90s and is now aging out a second time. We give you a straight repair-or-replace read. See furnace replacement and hot water tanks.
Boiler work on the homes that still have one
Some original Montgomery houses still heat with a boiler and radiators. Those units are well past every rule of thumb now, though plenty are still running. Our boiler replacement page covers the retrofit questions that matter — whether an old high-temperature radiator system will let a modern condensing unit actually condense.
Sump pump service near the river
Ground closer to the Bow holds more water, so sump systems in this part of Montgomery cycle more than they would elsewhere. More cycles means a shorter service life. Testing under load before storm season beats finding out during one. See sump pump installation.
Infill rough-in and fixture work
New builds replacing the original bungalows run modern PEX supply, high-efficiency heating, and increasingly hydronic radiant on the higher-spec projects. We work to a GC's schedule with written scope and inspection coordination.
Drain clearing on mature lots
Montgomery's older streets have established trees with root systems that find joints in aging drain lines. The signature is drainage that slows again a few months after each clearing. Camera inspection tells you what you're dealing with. See drain cleaning.
Why Montgomery needs a different conversation
A former town annexed in 1963, sitting between a river, three major institutions, and an active rebuild market. That combination doesn't fit a standard suburban service profile.
It was built as its own town, not a Calgary suburb
Montgomery developed independently before annexation, which is why the lot sizes, street pattern and original housing don't match the planned communities that went up around the same time. The plumbing reflects the era and the modest budgets it was built to.
A high share of tenanted property
Foothills, the Alberta Children's Hospital and the University all sit within a short distance, and the rental share here is well above the city norm. Landlords and property managers need scheduling, written scope, and durability over the cheapest possible patch — a genuinely different service relationship from an owner-occupier.
Second-generation equipment, not original
Unlike a heritage neighbourhood where you're looking at the original system, most Montgomery mechanical has already been replaced once. That means the age question isn't the house's age — it's when the last replacement happened, and that takes asking rather than assuming.
Redevelopment pressure means mixed-era streets
A 1948 bungalow can sit between two 2024 infills. Same block, three completely different sets of systems and three different conversations. We don't hand you between crews depending on which one you own.
The Bow raises the water table
Closer to the river, basements stay damper and sump systems do more work. It's the same pattern we see in neighbouring Bowness, and it's why we test sump equipment rather than assuming it's fine because it's quiet.
Hard water is the same here as everywhere
Calgary's hard water scales heat exchangers and shortens water heater life regardless of postcode. On a rental in particular, a water softener at the main entry reduces the callout frequency on everything downstream of it.
Montgomery Plumbers — FAQs
Do you work with landlords and property managers?
Yes, and a good share of our Montgomery work is exactly that.
What that means in practice: a confirmed appointment window you can pass to a tenant, written scope you can put against a property file, and an honest read on whether a repair will hold or whether the fixture is finished.
We'll also flag what's likely to fail next. On an empty unit it's usually cheaper to deal with it while nobody's living there than to schedule around a tenant six months later.
What kind of pipe is in a typical Montgomery house?
Usually a mix, which is what catches people out.
The original post-war plumbing was often galvanized supply with cast-iron drains. A lot of homes then had partial copper replacement somewhere along the way, so you get both in the same house — and occasionally PEX from a more recent renovation.
What you almost certainly don't have is Poly-B, which went into Canadian homes roughly 1978 to 1995 — decades after Montgomery's original build. The exception is a house re-plumbed during that window. Grey plastic pipe stamped PB2110 is the giveaway, and our guide on whether you need to replace Poly-B covers what to do if you find it.
Why does my hot water pressure drop but the cold is fine?
That pattern points at galvanized supply lines still in the system.
Galvanized pipe closes off internally with mineral scale over decades, and heat accelerates it — so the hot side scales faster and loses pressure first. Changing the tap won't help, because the restriction is upstream in the pipe.
The fix is replacing the affected runs with copper or PEX. In a house that's already been partly re-plumbed, that's often a smaller job than people expect, because some of the work is already done. We'll trace what's there and quote the remainder in writing.
My furnace was replaced in the 90s. Is it due again?
Quite possibly. A furnace installed in the 1990s is now at or past a typical service life, and that's the more useful number than the age of the house.
The things worth weighing are what it's costing to run, whether parts are still available, and whether repairs have started clustering. One failure on an otherwise healthy unit is ordinary; the third call in two winters is the system telling you something.
We'll assess it at no charge and give you a straight answer. If it has years left, that's what we'll say. See furnace replacement.
Does living near the river affect my basement?
It affects how hard your sump system works, yes.
Ground closer to the Bow holds more water, so a sump pump in the lower part of Montgomery cycles considerably more than one in a drier part of the city. More cycles means a shorter service life, and pumps tend to fail the first time they're asked to run continuously during a heavy storm.
We test under load rather than just confirming it switches on. If yours is past about ten years, it's worth checking before storm season rather than during one.
Can you work around a tenant's schedule?
Yes. We confirm a window before the truck rolls rather than handing over a four-hour block, which is what makes tenant access workable.
If you'd rather coordinate directly with the tenant we'll do that, or we'll deal only with you and let you arrange access — whichever you prefer. Just tell us which when you book.
How fast can you get to Montgomery?
Same day for emergencies — burst pipe, no heat, no hot water, water in the basement.
