Dan Martin

With the rise of big box hardware, it is so refreshing to find a good size, local store with helpful and knowledgeable staff...here was a time when retailers actually knew about the products they sell, and I'm glad Rafael Lumber has held true to that standard. This is also the best damn lumberyard around. I love it for all my DIY projects.

Had a great experience here helping my niece pick up lumber, etc. for her project. We had good help from the guys inside and out in the yard. Patrick was the best! He explained lumber talk so next time my niece goes in she will speak their language and it will go quicker.

Gabriel Wynn-Gould

My favorite place to go for lumber, finishing, or darn near anything hardware related. They have a great variety of items and brands to choose from. While they may not offer the very lowest prices, great deals can still be found. The staff are quite knowledgeable and are very accessible for questions. Lots of parking and a great location.
