Iain Stubley is the consummate professional - knowledgable, experienced, friendly, honest, insightful, thorough, and he conscientiously addresses clients' needs and concerns. Through his work and to our benefit, Iain has also made us keenly aware of: 1) The potential fire hazard that exists when lint isn't cleared from the dryer interior and venting (not just the removable screen); 2) Why smooth metal piping is a much more effective material for venting than ribbed plastic piping; 3) The money and time saved in having greatly reduced drying time - results we began enjoying immediately after Iain's efforts. I highly recommend Iain and his company, Dryer Vent Cleaner, and I encourage all of us to maintain our dryers with the same awareness as we do our fireplaces, smoke/carbon monoxide detectors, gas connections, and heating/cooling systems.
