I needed a garage door spring. If I could give 10 stars, I would, and here's why. Garage door springs aren't available anywhere, even at 4X the price from a year ago. Nowhere, period. I called Westside last. Should have called them first. They didn't have the spring either, but Sam said he would try to help. The next day, he called me back. He was able to MAKE ONE out of parts! That's service, man! He explained in detail how to install it, because he knows exactly how to do it. Thanks, Westside, you were worth the drive!

Do you hate wearing masks and want to feel at ease among your mask-less peers? This is the place for you. Nine out of ten staff were not wearing masks. Working in healthcare I am trying desperately not to get COVID so that I can take care of my clients in the event of an outbreak. Therefore this is not the hardware store for me. *I did report this business to department of health and encourage you to do the same if you've had a similar experience here*

Westside Building suppy has just about everything for anything! I always stop there first. The people are great! Always friendly and seem genuinely happy to help you find what you need or even might need. Way better than the big box stores like Lowes or Home Depot in Bellingham. I fully recommend anyone planning a home project to stop and check out what they have.

Sales staff was very helpful & easy to work with. Helped us get our specialty order the next day. Out in the yard a young man helped us load our items without us having to ask for help.
