Re: Remodeling company scam?
As suggested, trust your gut.
I can see a contractor being reticent of using cheap products provided by the homeowner because the quality of the job will likely suffer, as will the longevity of the project, both reflecting poorly on the contractor. This does not sound like your case, however. If you are using name brand, quality products, then a reputable contractor shouldn't have any issues installing them. Ultimately, the contractor is only responsible for their installation, any defect of the product would be up to you to file for warranty repair/replacement. Look for a contractor who doesn't mind installing your products.
I suffer from CDO ... Its like OCD, but in alphabetical order, LIKE IT SHOULD BE!!!
