Matt Sattersten, President - Merit Contractors, LLC

“We have been working with Alexander Lumber’s truss and lumber divisions for 10 years. Alexander has always prided themselves on delivering a quality product, in a timely manner to their customers. We look forward to another decade of continued business with Alexander.”

Scott Sevon, Managing Partner - MAW Chicago LLC

“Tim Barker, along with your team, has really worked hard for our firm. As we have many of our Jobs in the city and many in high rises, it tends to be very difficult with scheduling - elevators -loading docks. Between Tim’s hard work and the shipping team, we have a great and successful delivery experience. Tim and the estimating team at Alexander always takes pride in not only getting us prompt estimates BUT accurate ones. Like any business, things can go wrong, and what we at MAW Chicago have found is that the entire Alexander team always works fast and gets to a good resolve. Bottom line, they are considered a team member at MAW Chicago LLC!”

Mick DeBartolo - Principal, Rooms For Living LLC

I have been using Alexander Lumber for almost 20 years.  As a small company, Tim Barker and the Alexander team has given me the look and ability of a large builder to provide anything for my projects.  I have sourced lumber, siding, cabinets, millwork, windows and doors from Alexander.  Their deep and diverse offerings of these categories have given my clients a wide selection base with very competitive pricing.

 Alexander's service is impeccable. I can trust dates of product arrival from their suppliers and if there's ever an issue Tim is quick to notify me about a problem and with a ready solution.  The delivery team is conscious of the challenges of job site delivery and does whatever it takes to make sure material is delivered on time and placed where I need it or out of the way from other material deliveries.

 I feel Tim and Alexander Lumber are a big part of making my business a success with the professionalism displayed and required to set my company apart from other builders.

“I've been a long time customer of Alexander Lumber Company. The lumber, service, and advice is top quality.  Also, they will cut and size your lumber.  A service you don't often get at other yards.”

Greg DeWald - Elkhorn, WI

“Thanks for all your help!!! I appreciate you taking the time out of your busy schedule to help me, you were definitely the missing puzzle piece to link everything together!  And if you talk to John, please thank him also, and tell him I still tell stories about the tremendous job he did on the siding job. I'm hard to please, but he exceeded my expectations, and that's extremely rare.”

Kory Keller - Johnson Creek, WI

"Alexander Lumber made our remodel and update seem effortless!  We were so fortunate that our builder, T & H Builders of Helenville, works with Alexender Lumber and was able to introduce us to Meaghan Lewis, their Kitchen Consultant.  She has been amazing.  Her knowledge and experience allowed us to incorporate all the features we wanted, along with her awesome suggestions for options we never would have known were available! Throughout this whole process, the key factor that made it seem so easy, was the trust and confidence we had working with not only our builder, but with Alexander Lumber.  So a special thank-you to Meaghan!  You ROCK!!!"
