The coastal corrosion math

Salt air corrodes steel much faster than inland air. In our experience, a standard 10,000-cycle torsion spring in Burnaby gets to the end of its rating in about 7 years. The same spring in an English Bluff home — a clear view of the water, steady onshore wind — tends to fail at 5,000 to 6,000 cycles, somewhere in year 4 or 5.

TorqueMaster makes this worse, not better. The enclosed tube has almost no air exchange, so moisture that gets in stays in, trapped against the steel. We've cut open failed Tsawwassen TorqueMaster tubes and found two-inch patches of rust with the spring snapped clean through the rusted section. The enclosure that was supposed to protect the spring ends up working as a corrosion chamber.

Which Tsawwassen homes have TorqueMaster

Newer builds from the 2000s and early 2010s have plenty of them — English Bluff rebuilds and the first homes at Tsawwassen Springs, mostly TorqueMaster Plus. The 1980s–1990s stock in Beach Grove and Pebble Hill is a mix: a fair number of TorqueMaster Originals from door replacements in the '90s, and some houses still on conventional torsion springs.

If you can see the water from your driveway, your spring is rusting faster than the manufacturer's rating assumes. If you can hear the ferry horns from the terminal in your front yard, the same goes for you.

What we install instead

Oil-tempered high-cycle torsion springs are our spec for waterfront homes. The oil finish gives the steel some protection, and a 25,000-cycle spring has enough extra life to absorb what the salt takes away. We don't put galvanized springs on the water — the zinc coating doesn't hold up in salt air as well as people expect, and galvanized springs tend to fail sooner than oil-tempered ones.

Stainless-steel cables are the second upgrade. Standard galvanized cable is fine inland, but on a waterfront English Bluff home the cables sit along the door edge and take salt air every time the door opens. There, stainless is worth the $40 parts bump. We carry both on every truck and bring up the upgrade on the phone when the postal code starts with V4M.

On the high-cycle tier (flat-rate, all-in), sealed-bearing end plates come standard. Open bushings on a torsion system can seize within 3–4 years near the water; sealed bearings go 10-plus. On a Tsawwassen home we won't install open bushings even if you ask — they don't last.

The conversion question for Tsawwassen

Almost always: convert. In this climate the TorqueMaster tube is a corrosion liability. Replace it in kind and you're paying for proprietary Wayne Dalton parts that will corrode through again before the next service.

Convert to high-cycle torsion with sealed bearings and stainless cables and the salt-air spring problem goes away for 12 to 15 years. The math: one high-cycle conversion plus the stainless-cable upgrade, versus a TorqueMaster Plus in-kind replacement that costs more up front and lasts 4 to 5 years here. Over the same stretch, that's three TorqueMaster replacements against one conversion.

Honest scheduling

Tsawwassen sits at the end of the peninsula, so arrival time depends on where our nearest South Delta tech is when you call. Usually it's 15 to 20 minutes; on a bad day with Highway 17 backed up, closer to 25. We'll give you the real number on the phone rather than have you wait an hour wondering if we ghosted.

Same flat rate, same parts spec, same warranty as every other city we cover.
