Your Professional Catalytic Converter, DPF, Copper, Brass, Battery, and Scrap Metal Buyer in Calgary, Edmonton, and Lethbridge.

Welcome to Big House Converters Ltd.

Your Fair and Professional Catalytic Converter Buyer.

We've developed this site to reveal the truth about the converter recycling industry and our part in it. Having started in the converter recycling business back in June of 2005, Eric Grand-Maison began by cutting off converters from scrap cars. Starting from the very bottom, Eric has lead Big House Converters to become one of the largest buyers currently in Canada.

This site will save you from many hassles and costly lessons that we've picked up along the way. As the old saying goes, “schooling costs money”. We've found this to be too true in the scrap business; you won't find any schools teaching about scrap, but we can do what we can to help you with what we've learned.

A catalytic converter is an emissions control device that converts pollutants and toxic gases in exhaust gas to less toxic pollution by catalyzing a redox reaction (an oxidation and a reduction reaction). Catalytic converters are used with internal combustion engines fueled by either gasoline (petrol) or diesel, including lean-burn engines as well as kerosene heaters and stoves.
