how to test walk-in integrity?
How would I determine the integrity of a walkin? The box was installed used 15+ years ago, and the chef thinks he needs a new one. The thing holds temp just fine, but facilities dept wants to put a pitched roof over it and would like me to make the call as to its usefull life expectancy. I just fix the thing, I'm no prognosticator.

Well, I will put it like this.
Just a few months ago I ran into a similar situation at a Market. 15x15x9 walk in freezer that held temp but had ice burgs hanging from the ceiling, just about every joint was sweating on the outside of the box, floor was coming up.. was a mess. I had a long discussion with the owner of the Market who couldn't decide if he wanted to spend the money on a new box.
So here is what we did.
We turned off the box, and put heaters in it to dry it out for a couple of days.
We filled all seams with butyl, and covered the seams with an insulated channel. Attached the floor panels to the concrete and sealed the seams with silicon.
Re-insulated any refrigerant lines above the freezer and coated the top of the box with KoolSeal.. (the stuff I use on muh old singlewide in tha woods).
Box is dry and holds temps better than before. Helps when all that moisture is gone.
But in your case, if the insulation in the panels are dry, no leaking seams, then i'd just do a re-caulk just to strengthen the integrity of the seams and seal the top and let it go. The only thing I would suggest is to go ahead and replace the Evaporator(s) if they are 15 years old as well. Sure as the sun rises, you do all that work to the box and one of them will start to leak in some spot you cannot fix.
JMO.There's no such thing as normal,Just different kinds of crazy..
