The chaos started when the roofers showed up unannounced on a Friday without a permit (there was supposed to be a mid roof inspection). Apparently there was no communication between the scheduler and the contractor. This was my first red flag. The roofers came on the following Monday with a permit and did a good job as far as I am aware.I had 4 windows scheduled to be installed around my garage area and the day of scheduled installation I received a call saying the windows arrived at the warehouse but were the incorrect size. The installers came a couple of weeks later and had no knowledge of the previous install date or an issue with the window size. This was my second red flag. The windows were installed and look like they were installed correctly.Then there is the siding. The salesman, Paolo, was obviously a newbie. His estimate showed that they would re-ply the entire house under the new siding (I have all of this documented). His contract, however, had this very important item missing and I did not see the omission when I signed the contract. That mistake cost me $2000! There was also another $2500 extra of which only $500 was made clear to me before I received the final bill. The soffit had to be reinforced before the soffit material could be installed. No one asked me if this was ok or gave me a quote. Another $2000 expense. Paolo's quote included no specifics so it was up to the contractor to interpret what it actually was that Paolo sold. A more professional company would have a detailed quote with an itemized list of work to be performed. The contractor ended up performing extra work that he hadn't accounted for. Third red flag.This is the only company that suggested the roof should be installed before the siding. I should have known then that they didn't know what they were doing. Everyone I have spoken with before and since has said the siding should be installed first and now I understand why. The drip edge the roofers installed is damaged all around the house because the siders had to get underneath it (not the siders fault). The new gutters were installed after the roofing and siding was done so the drip edge underneath is cut up the entire length because the roofers had to cut around the old gutters. Also, there is damage on the roof caused by the siders (again not their fault as they spent a long time up there). The roofing and gutters should have been installed last and in that order. These people have no clue, apparently. Another red flag.The garage door I had installed came off without a hitch. It was the only thing that was installed as planned.There were two occasions where I was either billed for stuff I already paid for or billed in total for work that hadn't even started. I had to correct the billing lady on both occasions and sometimes had to go back and forth to correct her mistakes. Good thing I kept records of every bill paid and totals due or I would have been out thousands extra.I spent somewhere around $40,000 with this company when all was said and done. The contractors they hired (yes, none of the work is done by Colorado Window Source) did a good job overall. I signed the contracts the middle of December and the work was not complete until the first week of April. Many excuses saying the material or contractors were not available. The contractors said otherwise, almost everything was available locally and the contractors were available to work. The management of this company is incompetent to say the least. They should probably stick to windows. I would not recommend them for anything else.
