Sandium is the best contractor I ever did business with. I did numerous home improvement projects over the last years. I always selected very good, reputable companies. Sandium stood out of that pool of excellent service providers. The quality of work was great and the level of service outstanding. Sandium provided and great combination of craftsmanship, product knowledge and professionalism. I will definitely recommend them to family and friends.

I called this company from the phone book. The technician they sent was a pleasant, knowledgeable and honest. He could have taken advantage and order an expensive repair job. Fortunately, I had an unknown filter that was unchanged for ten years and caused the difficulty. I had a problem finding filters to fit my indoor opening but the technician had a year's supply cut for me and for not that much more than a run-of-mill size. I am always impressed with a scrupulously honest dealer in these days of so many scammers taking advantage. I feel the same way about the tire company at Lawrence and Prospect. And bad about brake place at Westgat

Good professional work. Courteous people, they show they really care. A little pricey? Could be. I couldn't get a state of the art furnace, it was out of my budget.
