This is one of those jobs where im kicking myself for forgetting to take before pictures. These are my “Almost before” pictures.

We started with a blank slate on this basement finishing job and are nearing the end stages. The final product will gain this home a non-conforming bedroom, a new full bathroom, and an expansive living area that maintains the charm of the existing wood fireplace. Stay tuned as we see this project through to completion!

Hi Everyone!

Nick and I are launching an online store for merchandise for 1st Klaes Construction. If you're interested in some merch, it is available to order here for 10 days. There is no markup on these items; we just want to cover the cost to get our name out there some more!

If you order something I will get ahold of you to arrange delivery.

Thanks!

-Jon
