if I buy product like carpet and tile do you offer installation? How long would it take for a house around 1200 feet where the kitchen,2 bathrooms laundry room and small entry which would be tile and rest carpet would take?

That would all depend on size. Square footage and quality of products used. Is the place vacant or occupied. What is the condition of the existing flooring . are there any repairs needed etc etc.

My best advice is to call them directly . Special orders may take up to 6 weeks or more . They did a good job on my install ! Good Luck

Yes the offer installation. Each installer is a separate sub contractor not a Lowes employee. Installation times will vary by job and contractor.

I know that they have installers. But you have to talk to them directly to learn about time frames
