I'm going to play devil's advocate here and also try to fill some holes in your story. This whole thing could have certainly been handled better, for both parties. It was an unfortunate mistake on their part, but would you rather they'd gotten it done faster with the wrong wood? Everyone makes mistakes. If I was faced with a potential 4 week delay without a stove I'd go to a used appliance store the first day, buy a cheap stove, bring it home, use it, then donate it later. In a 3 to 4 week period it's not unreasonable to think the furniture situation could have been remedied to make your lot more palatable. You could have prevailed on the floor man to set up your rooms and he would have likely complied. Now let me address the 48 days vs. 7 to 10 days. Where did the 7 to 10 day timeframe originate? It sounds implausible, at least the way I do floors. When the proper floor arrived, how soon was it installed? How long did it take to install? Did they start sanding and finishing right away? How many square feet of flooring was there to sand and finish? What type of finish was used. Answers to these questions will determine how long it really should have taken. Most of this is really pointless at this point because as the tired saying goes, it is what it is. From a retailer's perspective, if you didn't pay me, I'd lien your house. Once I liened your house (which takes my time and costs money) I'd be far less willing to provide any price concession. I would suggest you be proactive to make a settlement. The time you lost is water under the bridge but the floor finish is a real issue. Ask the retailer how much he would charge you to sand and finish the floor and suggest he deduct that amount from the bill. Tell him that in the future, you'd expect him to do the job for that amount of money, to keep him honest. In fact, make him give you a written estimate with no expiration date. I've done that in the past when something didn't turn out well and there was no time to re-do the job. Contact another reputable finisher for a quote so you can compare. Or get the other quote and deduct it from the invoice. PLEASE, PLEASE don't burden another finisher with a long tale of woe. While I might derive a little schadenfreude from hearing of the shortcomings of one of my rivals, I don't want to get the impression that a potential customer will be difficult to work for. Someone who tells me that a 7 day job took 48 days doesn't come across as reasonable when I know that it's not a 7 day job. Keep it short and simple.

He won't warrant it because you have made a material change by installing new flooring. Your only options will be to tolerate it or remove the new flooring and screw things down then replace the new flooring. Too bad you didn't check the subfloor before you installed the new flooring. Houses shrink and settle a lot during the first year or two. Your home is a good illustration of why you might want to wait to finish a basement or install a moveable basement ceiling. It certainly makes access easier to deal with flooring, plumbing and electrical issues.

Also I apologize for the incorrect placement of this post. I saw Home Forums and didn't realize I was in Garden Topics.

Ditto to Sophie. It would look silly to have hardwood just in the master. They already have hardwood in the main living areas ... it's the bedrooms, halls and stairs that are in question. If this were my house, I'd want hardwood in the halls and stairs first. Why? Because those are the spaces that get most walk-wear. Hardwood in those spaces and carpet in the bedrooms is fine. Hardwood in the master and not the secondary bedrooms is also fine. As for resale, are you looking at selling soon? I wouldn't replace any carpet unless your resale plans are very close -- carpet doesn't do anything for your sales price unless it is new.
