Dan, do you mean total removal of stucco?
Yeah...if it's started to show signs of coming off in a couple of spots, most likely it's not bonding very well. If it's just cracking up but hanging in...the stucco may be in better shape than the cmu's. You'll find out as soon as you start driving cut nails into the blocks to attach your lath.
The ONLY reason I'd hinge the job on the stucco issues deals with the Manufacturers Guideline for Installation & Warranty. You'll find EVERY bundle of shingles, composite siding, cans of paint even sheathing and decking....they either come with the Installation/Warranty sheet attached or by separate page. Some have a "Before Installation Please Visit our Installation Guide at
www.boguscrap.com to read prior to commencing work."
These directions are NOT just for your education. The manufacturers produce these documents as their
"Get Out of Liability" cards as well as...
"your warranty is void due to the improper installation of our world renown, wonderful and over-rated products!" because discuss the matter with your contractor(s) because we're OUT!<G
The last thing any of us want to hear would be
"Mr Newson Stone DID KNOW or SHOULD HAVE KNOWN about the proper installation of my clients manufactured stone veneer. To deny knowledge of this well publicized pamphlet is a disservice to the court and personally a daaaaaarrrrk day in Tennessee in the pursuit of justice for my poor clients and the damages to their home." ka-ching
....or something to that effect.
It's just business. They want this but they won't want to pay the price for it given all the little things to work around. However your estimate has to be honest as to what is involved and as fair as you wish to be in coming up with an $$amount. But....you have to be fair to both the company and its principal which I assume both being you. Too many good guys underbid jobs that look difficult in order to be a "good guy" to the rescue. This one has enough issues in front of you to be any less than 100% above-board and truthful. People appreciate that.
To save the folks some money....something that I've done in the past and still specify in rural settings for houses coming off of my board (or screen) would be something like this:
1)Test the entire exterior of the foundation for soundness and note all defects as well as any top coat that breaks bond from the CMUs.
2) Repair all defects and hairline cracking.
3) Pressure wash the perimeter of the foundation to unload mud and debris from the lower runs of the foundation at the point of contact with the ground. Pressure wash all dust and debris from the balance of the stucco'd foundation up to the bottom course of siding.
4) Apply a quality name Masonry Paint in conjunction with pre-paint wall preparations prior to the base coat.
5) Install a continuous "Savannah Walk" around the complete exterior at ground level contact to the foundation exterior.
A Savannah Walk is a 24in wide "dead zone" that is made with a gravel base and capped with either more #57 gravel or river stones, pea gravel or gravel. The idea is to give a space to any gutter overflow or rain that is not in shelter to the 16-18in eaves nearly two stories up. It's also a kill zone to maintain weed away from the foundation as well a treat for pest control to hose down on their visits. Either dig in or install a
pound in type of edging just to define the walkway.
I've used powered concrete buggies that I can fill with a chute and usually rent two along with a skid steer loader and gravel chute.

In any case...it's a good guy option to make.
I'm sure the ThinStone is a great material...they keep telling me how great they really are!!
However Dryvit told me how great they really were back in the 1970s and then there was Louisiana-Pacific, Certainteed, Masonite and other siding manufacturers that told me how terrific and easy their product are to the housing industry in the early 1980s.
They all had two things in common....they all took a beating in the Class Action suits that followed when their Forever Exterior products failed in the first few years. The second thing....damn if I didn't get some great lunches and dinners from the sales people to talk to me about buying these new things on the market!! The latter was a lot mo' better than the former of which I never partook. Well fed and but not a plaintiff. Not too shabby.
My old man was a builder from 1954 until he passed in 1987 and he would not allow me to build EIFS or composite sidings of that time. We always stayed with things that have proved out over decades and centuries before the hustlers moved in with aluminum, vinyl, composite sidings or EIFS.
I still stick with the real thing for masonry. I've never seen installation instructions on any cube of brick delivered to a job site.<G The rules governing brick, stone and stucco veneers are a part of the building codes with some supplements to watch out for...but they're the real deal and proved out over history.
