Jackson Lumber-Millwork

Good selection of lumber as well as general hardware. Knowledgeable staff.
My only complaint is the hours; since I commute, I’m rarely back in time to run an errand on a weekday (and end up driving to Home Depot instead even though Jackson Lumber is right next door).
I’ve done little/​no construction, but was getting lumber to build a bunk bed. After a little confusion (I don’t know the right terms, just the sizes), someone at the counter asked me the right questions to list the type of lumber I needed; and then I picked it up without trouble in the lumber yard.
I also got screws, nail plates, hinges, dowel, etc; and they have a selection of tools, and many aisles I didn’t make use of. (I initially mistook «Lumber» in their name for meaning that’s all they do, but it’s not.)

Felicia, why are you posting for a friend? All MA CSL’s are required now to take periodic continuing education to re-​up their licenses. Whether you take it ahead of time or wait until the last minute is irrelevant. I used the CSI Institute and although I didn’t learn a lot new in the class, it did qualify me for my continuing ed requirement and was honored by MA Dept. of Public Safety when I recently renewed by CSL. The fact that Jackson Lumber hosted the class made it an easy commute for me and didn’t take a lot of time out from running my business. The CSI Institute was taught by a current CSL holder and he related his 25+ years of experiences with the class. The class was also attended by a CSI Institute person that also worked for the Dept. of Public Safety that assisted in answering any questions regarding how to re-​up your CSL. They also served breakfast and lunch. which was just one less thing to think about that day.
Jackson Lumber itself has some great prices on materials and delivery is included. So no more self transporting slippery decking or pvc trim. The counter help is helpful and generally knowledgeable about product. And they often have new product demos and cookouts during the summer seasons.
