Repair of corroded stair support beams OR replacement cost
Job description
Five years ago I paid an Auckland contractor over NZD 7,000 to build a wooden staircase to replace an existing metal structure. The stairs installed had wooden steps and railings but the underside upper step support beams were steel with welded ends attached which rest on and are bolted to, an intérim small deck leading to the smaller lower staircase to the ground. The beam end plates have seriously corroded compromising the structural integrity of the stairs as well as their safe use. I need to know if the corroded ends can be repaired and the lower end of the upper staircase reinforced because of the rusted beam ends or if both beams require replacement or indeed, if this is required would there also be need for additional design changes. I was quoted NZD 11,000 back in 2018 for galvanized steel staircase replacement which in hindsight I wish I had opted for instead of the wooden structure supported by quickly corroded support beams. That said, I had assumed at the time that the contractor would have used wooden support beams (the request was for a wooden staircase), or, using steel ones, had endured the beams were properly corrosion protected against Devonport sea air atmospherics, with a lifespan well in excess of five years.

Damien and DCD ENGINEERING have done an excellent job repairing stairs built only five years ago by another construction company in which time poorly treated steel stringers had corroded to the point that the safety of the staircase was compromised. Damien was excellent communicating costs of labor and materials and answering all my lay-person’s questions. The quote was reasonable, the work completed on time, and to a very good standard. I have no hesitation in recommending Damien and DCD ENGIN.
