Most eavestrough problems on Calgary homes are fixable.

Most eavestrough problems on Calgary homes are fixable. A joint that has opened up after five winters of freeze-thaw movement, a section that has sagged because the original spike-and-ferrule mounts worked loose under ice weight, a downspout that was placed 15 years ago without considering where the water actually ends up. These are not failures of the material. They are failures of installation or time. We find the actual cause and fix it properly.
Chinook Exteriors installs new systems, repairs existing ones, and carries out seasonal maintenance across Calgary and the surrounding area. We install Gentek eavestrough systems and bring long-standing gutter experience to Calgary homes.

Every new installation includes a full assessment of your roofline before we fabricate anything. We calculate the correct slope for drainage, place downspouts based on where water needs to go rather than where they are easiest to reach, and confirm the fascia condition before attaching anything to it. Getting these details wrong at installation is the main reason homeowners end up calling for repairs within a few years.
When an entire system reaches the end of its life, a full replacement is usually more cost-effective than continued piecemeal repairs. Vinyl systems that have become brittle, older sectional aluminum with multiple leaking joints, or any system where the original slope is incorrect throughout, all warrant a full replacement. We remove the old system, inspect the fascia for any damage that occurred underneath, and install a new seamless system colour-matched through the Gentek colour range.
Typical installation cost in Calgary: $8 to $14 per linear foot for a 5-inch seamless aluminum system. $13 to $17 per linear foot for 6-inch. Most Calgary homes need 150 to 200 linear feet. Removal of the old system adds $300 to $600. We provide an itemized written estimate after a free inspection.

Repair costs depend on the type of problem, how many sections are affected, and whether any underlying hardware or fascia needs attention at the same time. Here are the ranges we see on typical Calgary jobs:
: $150 to $400 Quick turnaround. Includes sealant strip, clean, and reseal at corner joints.
: $250 to $600 Per section. Resolves the root cause of sagging rather than re-spiking the same holes.
: $300 to $700 Includes colour-matched Gentek aluminum and proper slope alignment on reinstall.
: $200 to $500 Per downspout including extension. Outlet repositioning quoted separately if needed.
: $300 to $800 Depends on how many sections need to be re-hung and whether fascia repairs are involved.
: $500 to $1,500 Most repair calls involve more than one of the above. Written estimate provided before work begins.
We carry out seasonal maintenance visits in spring and fall. Here is what is included:
Chinook Exteriors does not offer standalone gutter cleaning as a service. If debris accumulation is a recurring issue at your property, the most effective long-term solution is an Alu-Rex gutter guard system installed over your existing eavestroughs. It keeps debris out permanently rather than requiring a cleaning schedule twice a year.

The right answer depends on the age of the system, the number of problems present, and the cost comparison over the next several years.
Here is a straightforward guide:

This usually means the repair addressed the symptom rather than the cause. The most common examples are a joint that was resealed without correcting an underlying slope problem, or a sagging section that was re-fastened with the same worn spike holes in the same fascia board. If water is pooling in a section due to incorrect pitch, the sealant at that joint will keep failing regardless of how many times it is resealed. We inspect the full system and diagnose the root cause before quoting any repair.
If the problem is isolated to one or two sections and the rest of the system is in good condition, repair is almost always the right call. If you have widespread joint failure, multiple sagging sections, vinyl that is cracking in cold weather, or a system where the same repairs keep recurring, replacement is usually the better investment. A free inspection gives you a clear answer. We will tell you honestly which direction makes more financial sense for your specific situation.
Twice a year is the standard recommendation for Calgary’s climate: once in spring after the freeze-thaw season ends, and once in fall before freeze-up. After any significant hailstorm or wind event it is also worth a look, since hail can dent sections and restrict flow without creating an immediately obvious leak. Most problems we find during a spring inspection could have been addressed cheaply in fall if someone had looked.
Yes, but the repair depends on what caused the separation. If the spike-and-ferrule mounts have failed because the wood behind them is still solid, we upgrade to hidden hanger hardware which holds far better under ice loading. If the fascia board itself has deteriorated, the fascia needs to be replaced before we can properly re-attach the trough. We assess both at the inspection so you know exactly what is involved before any work begins.
For urgent repairs where water is actively getting into the fascia or foundation, yes. Sealant applications work best above roughly minus 10 Celsius, so we work around conditions where possible. Section replacements and hardware upgrades can proceed in most winter conditions. We assess the situation at booking and give you a straight answer on what is feasible and what is better left until spring.
