I put up a 30x56x14 Morton last fall, and I finished the interior this spring.
Going into the process, I started set on a Menards building due to cost. After getting labor costs to erect it (my time is extremely limited), I started reaching out to other manufacturers and builders. I looked at Lester, Reaves, Morton, etc. Lester was the leader and were great to work with. Morton was high off the bat. When it came down to it, I was ready to sign on with Lester but when the Morton guy caught wind of it he became very aggressive and beat the price from Lester for the same spec building (bigger actually).
Material and craftsmanship, Morton is the leader, but you do pay for it. For me, this is a building I will have to look at for the next 50 years (hopefully). I was willing to stretch my budget a bit to get something that will last a lifetime.
Some suggestions if you do go the Morton route:
Ask what the standard width and length dimensions are off the bat. They will quote whatever dimension you give them, but often they have standard lengths that are more in line cost wise. Let them know that cost is important and ask for suggestions to help keep the building within budget.
Understand the insulation package and how best to incorporate that. The fiberglass batts they used are presized for the pole spacing. I’m amazed how cool the building ha been this summer and I am excited to see how well it holds heat this winter.
Get the options you want now. Yes you can always add on in the future, but porches, windows, cupolas, etc. are great finishing touches that really make a building stand out.
The post system they use with precast concrete footers is a really neat system, no wood in the ground. This should help the building last for years to come.
Morton is willing to act as GC for excavation and concrete if needed. I handled site prep and they did concrete and insulation. Understand who is covering what and what is included in your quotes. In addition make sure concrete specs are up to your requirements if they handle that.
Any questions, feel free to ask.
