DEAR POLE BARN GURU: Do you have to use the same size posts on the end walls even if it is non load bearing? so if I use 6×6 posts that hold the trusses can I use smaller lumber on the non load bearing ends?
Thank you. CAMERON in BOISE

DEAR CAMERON: This is why it is essential to invest in a post frame building kit package which includes engineering which is specific to your building. The engineer will specify the minimum size requirements so you do not have to get into guesswork. Most pressure preservative treated timbers in your part of the country are Hem-Fir, which has a very low value in bending once it has been incised. Chances are very small of a 6×6 working to support the interior trusses, unless you have a very short eave height and a protected site.

In direct answer to your question – often the endwall columns can be smaller dimension. This article explains some of the reason why: https://www.hansenpolebuildings.com/2014/08/lumber-bending/.

DEAR POLE BARN GURU: We have a pole building that had a 12′ X 12′ slider door that was recently damaged and needs replaced. Can you point me in the direction I need to go to get a replacement. We wanted to replace it with an overhead door but do not have sufficient clearance for our motorhome. JOYCE in FRANKLIN

DEAR JOYCE: Replacing a sliding door with an overhead door is no simple task as the opening sizes are completely different. If this is the direction you truly want to pursue, you should start by contracting with a competent local engineer who can evaluate what you have and determine how to best make the structural changes necessary to fit the overhead door into your soon to be remodeled building. Expect this to be an expensive undertaking, even if you are doing the work yourself.

If you decide to just replace the sliding door, visit the ProDesk at your local The Home Depot®, as they should be able to assist you.

DEAR POLE BARN GURU: I recently purchased a pole building with vinyl insulation that is really dirty. Is there any way to clean the insulation? Can I spray paint it? I’m afraid to get it wet. Let me know your thoughts asap. Thanks LUCILLE in McHENRY

DEAR LUCILLE: You are finding one of the reason I personally do not recommend the use of vinyl faced metal building insulation. As long as the insulation has not gotten brittle and cracked, you can wash it with any sort of cleaner which does not react negatively with vinyl. Most folks who get to this point use dishwashing detergent, warm water and a sponge. Take care to not rip the vinyl facing. Any cracks or tears in the facing need to be repaired with a good vinyl repair tape (white duct tape works). I would not suggest power washing, as the force of the high pressure water will probably rip the facing, leaving you with an even bigger mess. Spray painting would not be an option unless the facing has been cleaned, at which point there would be no reason to paint it.
