Let them know you will get another contractor to finish the job and will give them the remainder. I would call and talk to them 1st as this would be the easiest option.

Have you tried communicating with them at all since the windows were installed? It’s possible they’ve reordered the damaged window (or parts for it) and just didn’t communicate effectively with you. It’s also possible that they dropped the ball between the installers and the personnel who handle follow up repairs and punch list items.

From the information you've provided, your contractor has completed most of the job scope. You've only paid 40% of the contract price and haven't yet been billed for the final amount due. I wouldn't consider a two-week idle period to be job abandonment--it's most likely the time required to get the replacement window for the damaged one. I think the only thing your contractor is guilty of at this juncture is not keeping you informed.

The fact that its only one window, i dont see why you would hold $7500. When that happens, my customers hold the amount equal to one window. I have a clause in my contract regarding that. If a customer wanted to keep $7500 for one window, i would not be happy and would never let that happen.

if you are attempting to hold such a large amount for one window, i can understand your contractor not going for that.

Pay the guy for the work he did and have him order a new window which he has to do anyway.

Right. But he hasnt been billed.

Took my contractor 6 weeks to send me a bill for the remaining balance, though it was only like $2,700. Trust me, they wont forget. Call them and communicate to understand whats going on, especially if you’re unhappy with them.

2 weeks is on the short side of what it takes to get replacement parts. I would just call them ask for a status. I am sure the parts are on order and they are waiting on them. You need not consider any other options until you talk to them and I am 100% certain that your contractor is not walking away from 60% of the job while they are waiting on 1 window.

Sounds like poor communication, maybe the installer is a deadbeat, maybe not. Either way, no, you are not entitled to keep all that money under almost any circumstance. They won’t forget, and you can’t wait it out. Telling you to hire another contractor to finish the job is terrible advice and will have you paying twice. Call this company for an update and tell them that you are unhappy with their lack of communication.

I wrecked a $300.00 faucet on a $2,500.00 sink replacement job. I would not allow the customer to pay her $2,000.00 balance or even partially (although she offered) until the replacement faucet arrived and I had successfully installed it. Only after she was delighted did I collect the $1,700.00 balance due.

I completed another replacement on Wednesday, but wasn't able to refinish her Corian tops until yesterday. I collected nothing additional until then and again refused partial payment.

No partials. Sit on all the money. I would be ashamed to ask for a penny from an unhappy customer. Ever.

"I havent been billed and havent heard from them since the windows were put in over 2 weeks ago."

As stated above the window takee time to come in. The fact that he has not billed you tells me that he knows he owes you the window and is ot going to bill you more $ until he is finished. IOnly thing he may be quilty of is poor communication. Just my .02.
