HI Emily Carpeting bedrooms is only dictated by your budget. The only variable is the price of the carpet, all other costs (installation, smoothedge, underlay) will be the same no matter what you choose. When you say remove wooden floors....do you know what is already installed? If you are only wanting to take the wood from the bedrooms but leave it in hallways etc, then the cost to remove wood planks (laminate?) may be around $20 per m2... A lot depends on how the timber was installed, so I think it's best to get in a professional and get a free quote. Good luck.

Carpet has come under fire because of the allergy/asthma reactions. Carpet can hold dozens of pounds of human skin/dust/mites in it. It can never be fully cleaned nor can the dust be completely removed. Because of this, many people are looking for solid flooring options which reduce allergens, reduce asthmatic events, are easier to clean and last longer. High end carpet (the stuff that is worth more than hardwood) still has its place in high end homes - often times in luxury bedrooms/luxury appartments (noise issues have to be taken into consideration) but on the whole, the general public is shying away from wall-to-wall carpets. Cork flooring is seeing a huge increase in sales because it "takes over" for carpet. Soft, quiet, warm, easy to clean, hypo-allergenic, antimicrobial, instect resistant. It is the "go-between" type of flooring for people used to carpet who need to move to solid surfaces for their health. As Canadians, we love this flooring because it is so warm.

What did you end up doing?

I'm guessing you are from NZ (kiwi) :) The handy sanders did our floors - http://www.handysanders.co.nz/. They did an AWESOME job and are reasonable priced. I would definitely recommend.
