Considering making some changes that involve different areas/rooms of the house. Wondering if it is more economical to go to a "one size fits all" source like a dr. remodel, or big box store planning department, or, to personally purchase each item or materials, and hire the trade needed to install ? To clarify a bit; do you end up paying a one stop shop for acting as general contractor, while at the same time having no control or choice over the workers sent to do the work ? Hopefully some will offer advice based on personal EXPERIENCE, not just what they would do. We already know it's probably easier to just turn it over to a business that acts as a general contractor, but is that also a huge risk since you have no control over the sub contractors work and no "come back" should it be shoddy ? Again to clarify, asking these things since a good friend has a kitchen remodel that resulted in a huge flooding of the kitchen and a great deal of damage even to walls, base boards, etc. The big box store stated the installers are NOT employees, they claimed they are only responsible for the materials they provided, no liability for work.
Thanks for sharing your experience. If you have used the one stop places, how much do you estimate (in percentage) you paid for this service ? 5%, 10% 15%, more ? ?
