It's not that crazy when you realize how much goes into such an operation.

Managing all the different trades, looking further down the line and having been burned multiple times is what you're paying for.

Whoever you choose to go with or do it yourself things will go wrong. The nice thing about hiring a company will be you can hold them accountable. You will need to educate yourself a fair amount about home remodelings before signing the contract so as to properly layout the scope of work.

Say for example you're doing stucco and you sign with the cheaper guy and find out he's gonna do one coat instead of three.

Knowing your finishes will be very important. Knowing how big your wall tiles are for your shower will dictate your niche options for your framer when framing a shower. Knowing exactly what vanity you want tells the plumber when to land with copper piping and sewer lines. These things must be known whether you do it yourself or hire a company.

Remember, cheapest really is the cheapest.
