One Alliance Group Ltd

We had previously tested and confirmed the Vermiculite insulation in our bungalow attic was asbestos free, however, decided to replace and upgrade. After contacting several companies, Grant at One Alliance was the most punctual in responding and the only one who actually came out to inspect and quote. He was very thorough in reviewing the entire attic and pointed out areas of concern such as ventilation and poor bathroom vent ducting. The estimate was detailed, easy to understand and competitive. On the day of the job, Grant and the crew were on time and kept me informed on the progress. We had the layer of spray foam applied first as a vapour barrier followed by the blown-in cellulose up to R50. A new vent was installed to improve attic air flow and the bathroom duct work corrected. I subsequently did my own detailed inspection of the roof, venting and inside the attic. I was extremely impressed by the level of detail in the overall job plus the attention given to clean up and removal of all the old insulation material. We noticed an immediate improvement with more even and consistent inside temperatures while the outside temps fluctuated greatly. Looking foward to the next full cooling and heating seasons to monitor the savings. Grant even followed up with photos of the work in progress and delivered on all commitments. Great job Grant and team!
