Loc Tite Interlocking

I'd like to share my expirience with having Loctite to complete driveway / walkway interlocking and porch copping. The project was completed 1 week ago and in it is now in the phase of addrssing several issues.
I will simply list what I liked and disliked:
What I like:
- Reasonable price if you manage to negotiate
- The owner (Greg)did accommodate my request to change the stone as it was not ordered yet.
- Loctite try to address immidiate issues which I wish not have to begin with (moving copping step stones, shifting stones, joint sand is washing out).
- I wasn't asked for all these multiple payments upon excavation, upon stones delivery etc. I paid the ballance after the job completed + tips (even with the issues which I discovered later)

What I disliked:
- Waited almost 2 month from the time I have signed the contract where where was specified that job must be completed by July 1st, it was completed near 4 weeks later.
- Waited 3 weeks between my payving was taken off until interlocking job completed.
- Had to manage / oversee the project coming home early or durring the launch, otherwise I would get not exactly what I asked ((placement of grey and beige stones).
- I was expecting that stones will be installed with one of 3 pattens sugested by manufacturer, I was flexible with which pattern they do it and didn't put in the contract and I was WRONG. Loctite installed the stones randomly. Why is it bad? Because now I have many random places where joint line between breeks goes continiously straight along 5-7 briks and this becomes a small "river" when rainging and washes joint sand out. In fact, I came home during the launch and have asked to use a pattern but was not able to get one as it was not in the contract. More then that, a crew member who did placed the stone on the driveway doesn't know any pattern and told me that I'm first customer who wants a pattern. Nice.
- Several issue immidiately after job "done":
1. 2 copping stones on the top step (porch level) were not glued weel and where shifitng. Ryan (lead of the crew)fixed this, in fact, he was very responsive to come and address the issue.
2. About 8-10 stones where shifing on the porch - Ryan came and quickly re-packed most of them. 1 or 2 still moving.
3. Border stones (about 10) in a curved area of my walkway before steps are moving when you stay on them. - Promissed that it will be fixed by installing a retainer. - not fixed yet.
4. Jointing sand that was used to fill joints between the stones is washing out. I just learned that Polymeric sand needs to be used, which ardens after weting, and stays much longer. Called the owner (Greg) about this issue, he told me that I didn't pay for polymeric sand. Excuse me? I was never told that there are different types. In fact, the price difference between cheap sand and polymeric as much as 8 dollars per a bag 20 kg. Now, I have to spend 1 day to wash this sand out with pressure washer, let it dry completely, the waste another day to spread polymeric sand through all joints on 800 sq feet area, and wet it. An all this because Loctite saved $100-120 by using a regular sand. I would now - I would pay. I will pay extra cost any time, just make it right.
- Grass was killed in several places ( I think because they keep on the grass running motorized cutting tools , maybe I wrong)
- Salesman (Scott) is a friendly guy and he will tell you several time that he will take care of you, but you likely will never see or hear him again after you paid comissions. He spend just 20 minutes with me, did beat other estimates, signed me and that was all (this was a reason that I had to change stone type, and some design, we never discussed patterns, we never discussed polymeric sand, etc). Just before the excavation task to begin, I have decided to do interlocking of the entire driveway (not just walkway as originaly), was making an arrangement on additional cost with Greg, and it was higher then estimates given by the salesman originaly. I just agreed to pay more, whatever Greg asked. What do you think next? The salesman shows up the next day to get his 10% comissions. Question is what for? OK - I paid.

Overal: The job is done, minor issues with border stones and washing sand is still waiting Loctite's attention. I hope Loctite will deal with it. The worst case I will have to hire another contractor to fix it and put polymeric send. I'll update review on this one. The driveway still has to go trough winter to show how deep the excavation was done and how much gravel is there. I will make the follow-up review next Spring.

Tips:
Learn best practices for interlocking jobs, be informative about how it supposed to be done. Include everything in the contract, take your time and don't rush, let the salesman spend time with you and earn his comission:
Specify pattern, what stone type and color, specify on the drawing where is a brick of different color, specify how deep excavation is (inspect it), specify how many inches gravel (inspect it) and amoint of screening sand, write that polymeric sand must be used, specify deadline date when the project should be completed and what happens if it is delate. Read on the back of the contract (if you can :-) ).

I thank you for reading my review and hope it will help you to make informative decision when you hire a contractor to make interlocking for you.

UPDATE: Loctite (Ryan) came to address outstanding issues. He has fixed moving stones by installing metal retainer.
I have agreed to pay $0.50 per sq. feet to re-sand the driveway with polimeryc sand. Ryan was able to wash out existing sand on 0.5 inch depth. I have requested 1.25 inch depth as required by technical specifications for application of Dynamatrix RJ+ polymeric send. Was told that this would take too much time, so I have to do it my self (accomplished in 60 minutes), just got derty like hell. After 60-90 minutes, when driveway was almost dry from the top, we have applied polimery sand, however, only 4 bugs of RJ+ sand where available at Loctite, and we have left with 200 sq feet unfinished. Was told that their supplier (Bestway Stone) is out of this sand and we have to use another. Another crew member delivered 2 bags of regular (not pymeric sand) which they were going to use. I'm refused, of course. Later we've got additional amount of Technoseel RG polymeric sand from Rona. It was already late when we have applied sand on the remaining area. After misting/wetting and drying the area of 100 sq. ft (re-sanded the latest), had most of the stones stained by polymeric sand. I have posted a picture for your judgment. Next day I have called Ryan and explained the "staining" issue. He sad that it can be easily washed out and that he will bring me in the morning his powerfull pressure washer ( mine 1700 PSI can't wash it out) so I can wash all driveway myself. Well, I was OK to wash it my self. Perhaps, I'm used to do myseld many things within this project anyway. Unfortunately, I haven't seen anyone since then, and 100 sq ft of my driveway look very ugly.
Anyway, I'm thankfull to Loctite for the fixes which they did rigth and I'm very unhappy with re-sanding part, especialy the ugly area which was done last.
