I have a contractor at my house putting up new siding. The start date was Monday Apr 12, and we are now over 1 week into the production. All they have completed so far is siding the front and the side of my garage.

They started putting siding on the front of the garage when we realized they were using the wrong product. They had to remove it and put the correct product up.

They are nailing the Tyvek to the house using ordinary nails (not washerhead). They are not taping the Tyvek seams. It is already blowing loose.

Friday they only worked from noon to 3:00pm. The put soffit on the front porch (about 30 sq ft) and now I can't open my screen door. The corner of the door drags on the soffitt.

Yesterday they called at 10:30am and said the truck was broken, but they were on the way. I called the siding company at 4:00pm asking where the workers were; the workers called me back and said they told me they wouldn't be able to make it (which is a lie).

They are not very clean workers - they throw their cigarettes in my yard/driveway, they have broken a birdhouse.

On top of all this, their workmanship on the siding leaves a lot to be desired. The trim pieces are sloppily fit and loose. Some pieces are already falling off. The flashing is visibly wavey.

What is the best way to handle this with the siding company? I have already paid 1/3 deposit - do I withhold payment until I am satisfied with the work? Do I negotiate a steep discount?

I did call the siding company yesterday and told them we were not happy with the work; they promised to send someone out today.
