Central Fairbank supplied me with lumber for a renovation recently. They have a good selection of lumber and are fair about returns. The delivery was on schedule as well. Also, the price is much better than the big box stores.
The salesperson was very helpful and knowledgeable about their products. I went in with my blueprints and they provided me with a quote for the approximate cost as well as additional tips and advice.
Everytime we've gone in the staff has been very welcoming and helpful. They do not hesitate to give samples and answer questions.
