One Alliance Group Ltd reviews (15)

I called three, well reviewed foam insulation specialists to quote insulating a large crawl space under my kitchen and dining room area. Of the three, Grant from One Alliance was by far the most diligent, careful and detailed in his quote. Tt addressed and included more than just the foam insulation. He spotted issues with our duct work, and had an excellent solution for dealing with the dirt floor in the crawl space. Even though his quote involved more work, his pricing was very much inline with the competitors, who simply wanted to spray the wood ceiling of our crawl space. The crew showed up on time, ready to work. They arrived with a very large equipment truck, and deployed very quickly. I would say that after parking in my drive, they were in the crawl space within 15 minutes. The men were extremely polite and courteous. Grant took responsibility for the QC, and promised he would be there for the last hour of the work, which took just under a day, as quoted. He showed up about two hours before the end of the job, and insured the details agreed upon in the quote were fulfilled. The men made sure that my property was clean and as free of debris as humanly possible after they finished the work. I am very pleased with the quality, professionalism, speed and timeliness of One Alliance.

I never write any review in my life; however, i believe this company, perhaps the crew deserve a good credit. The story is i am rebuilding my house, of course no neighbour like about this, but when these professionals come to the job site, first thing they do is to inform my neighbours what are they are doing and when they will finish. job went well as what they suppose to do. they also clean up the job site better than anyone else, they take another step to make sure my neighbour's place is clean up too!! neigbour is happy, no issue, that's great. yes, i will recomend them to my mother.

Very reliable and professional. Everything was done as per contract. Good cleanup job afterwards. Installer Keith parked his van on the road instead of on my interlocking driveway as I have requested even though it is more inconvenient for him when bringing the hose into the house.

Sales associate and service men were all very friendly, professional and efficient. They ensured their equipment could fit into our premises, then took measures to ensure everything was tidy and wouldn't ruin our floor. Very satisfied with their staff and service!

One Alliance salesman went thru different type of insulation materials and help me to decided which is the best on cost and effectiveness. after the job was completed my family feel the difference right away. thank you. you are professional, very good customer service
