salmo,
I built for them probably 12 years ago.I believe that they had an affiliation with kingston lumber back then.I have heard that they have switched owners since then.
I think there biggest problem back then was that they offered support in the form of an experienced superintendent.I never met him and I believe the clients were cheated out of that service.I believe that other problems actually stemmed from kingston lumber themselves.
I remember one house that had a good sized12\12 hand cut roof.All the ceilings were vaulted.When kingston sent out the roof load, the 2\12 rafter material was essentially, not long enough for the main body.Somebody had taken all of the spans and forgot to do the math for the actual rafter lengths.Accidents happen.We went to kingston lumber to address this and were told the lumber package was right.We could not get them to even come out and look at the package.
On this home the homeowner-general was out of town for two weeks at a time for work.He finally got back and got kingston to rectify the problem.Turns out that kingston, had lost there architect that did there take offs.The manager at the time had tried to do the take off and was trying to cover his mistake.
The plans on this project called for all the ceilings to be vaulted.Bathrooms closets everything.We called the homeowner and expressed our concerns.He wanted it per plan.We spent a week pony up the walls.He gets back,walks into the house,and finally realized what we were talking about.So we started dropping the ceilings.Of coarse he paid for this.He was a great guy.Probably should not of qualified for U build it,being as he was gone so much.He actually took responsibility for this and paid us for our time.Problem is that back then, we were booked and these problems threw our schedules way off and left other customers waiting for us to get started.

I remember another project,actually the last one we did for u-buildit.Home owner found out he could save 100 dollars by having only one lumber drop.So we ended up with two floors and a roof load dropped all at once.Really should not be big deal except that this project was already stuffing the property lines..There was no room for us to scatter the lumber drop.Of course kingston did not stack the lumber package in an order that would help us.First floor on the bottom basically,so the entire package had to be taken apart and put back together in an order that worked for us and left room for some work on the lot.Another note is that hemlock does not like being unband and left out in the sun.This left us with a lot of lumber twisting up and needing to be culled out.When you bid by the square foot this kind of stuff hurts.

I always thought the idea was good It just did not have the wrinkles ironed out of it.Acting as a source for reputable subs is a huge asset alone.I am not wanting to bad mouth u-buildit as I know nothing of how they operate today.

Did one out in port ludlow.Right on the golf course.The home owner was a retired couple.They were out every morning to make sure everything was going as planned.They had basic building knowledge but most importantly they were there to progress the job.They did not have there own jobs to take care of first.I remember building a small garage for his golf cart.Then he found he was not allowed to use his own, had to rent on from the course.
