Questions before I start removing the carpet

No vinyl flooring under our carpet except for about 1 foot overrun from kitchen flooring.

We replaced kitchen linoleum with new linoleum
We recarpeted the living room and both slides.
We had an independent flooring guy lay the new stuff.
Slide out carpet was cut to fit plus 2" extra then taken to shop where leading edges were bound for a clean edge. Then they came back couple days later to install.

Stairs/hallway/bedroom carpet wasn't changed.
The flooring replacement in kitchen/living room was done due to MAJOR water leak. Hot water line blew off back of water heater (under kitchen cabinet) during the night. Flooded the rig....water pouring out under slides and 2" standing (flowing) water when dog woke us BARKING.

I ripped out the carpet/padding and linoleum to SAVE the subfloor
Only took me 10 minutes as I wasn't being too 'gentle' about it. Utility knife and had at it :B

Thanks, donn0128! I love the part about the installer getting paid by the number of staples he uses! What did you replace your carpet with?

Thanks, Old-Biscuit. I was afraid the cabinets were set on top of the carpet, because that would greatly simplify the original build. What did you replace the carpet with? Did you only replace the main floor area, or did you do something with the slides, too? Can you give me an idea of how long to plan for the whole job, from ripping out the carpet to finish putting down the vinyl? Are your steps carpeted, or are they wood? Mine are carpeted, but I'm considering installing wood treads.

Typically there is a layer of vinyl flooring laid down first. Then it there is carpet over part of the area. Then base cabinets are installed right over everything. Carpet is generally laid by somebody with an air stapler who gets paid by the number of staples he uses per day. There will be literally thousands of staples everywhere. A pair of side cutters, a 3 inch wide putty knife, a good razor knife, and a straight blade screwdriver and hammer should be all you will need. Don't forget your knee pads. Use the putty knife to slide across the entire floor and the screwdriver and side cutters to pull all staples found.

Our carpet was laid down with 'tack strips' around edges by walls, with staples along front edges of slide outs and cabinets were set on top of carpet and then screwed down. Padding was stapled to floor..........LOTS of staples

We cut the carpet at cabinet bases then yanked it up. Yanked up the padding and then spent couple hours on hands/knees with a flat blade screw driver and pliers removing staples. Pried the tack strips up with flat blade screw driver.
