Is there a reason you not asking your builder to quote this as a Change Order using his trim carpenter?

What type and size of crown moulding is going up that would make a difference. Is it going to be painted or stained?

There's not enough detail to make an informed judgement. How many rooms are involved? How complex is the room geometry (simple squares or rectangles versus lots of ins and outs). Based on your use of the term "crown flex" it sounds like the quote is for PVC extruded molding. How fancy is the profile? How high is the actual crown itself? Is it for a single piece crown or multiple pieces?

Because it’s way over priced going through our builder.

Crown molding is very expensive, and I can't really see why. I understand that it's detailed work, but 6K+ is an awful lot.

If you want to know if a quote is reasonable, you will need a minimum of three detailed quotes on your project preferably more. Note how long each finishing carpenter spends on your house assessing his/her work in preparing the quote, that is important to know whether they know what they are doing. each quote should detail the number of rooms or linear feet, size and type of molding, and completion clean up protection of house etc. by having detailed quotes you can asses yourself what is reasonable and what is overpriced. Don’t necessarily go with the lowest, be discerning and choose wisely by the detail in the quote and the carpenter quoting and referrals. Make sure they are insured and professional.

When getting bids, it's very important for each person to be bidding on the same scope of work -- same materials, same everything.

Crown moulding looks great installed & painted correctly, a large negative when not.

Make sure you understand the installer's quality of work & credentials, and whether paint is included.

Production builders have a different way of pricing extras. Often baseline finishes are often undesirable low margin foot in the door for design centers. A few weeks ago I walked a higher end project selling their models at 220% of their base models.

I always rough figure $10 a foot As the starting ballpark for real wood crown of some size, installed on no more than a 9' ceiling, painted and finished. Sure you can get tiny little 1 7/8" crown, just primed white MDF installed for less. (Which is probably what you are being quoted.) And you can pay more than double for a 6 pc multi part 12" crown composition installed on walls and ceiling.

So you are installing crown AFTER you move into the house, which means the painters have to come back in and paint the crown as well as the walls and ceiling. Or they just paint the crown as long as you are happy with seeing a line of caulk where the materials transition. None of this will be covered by your builders warranty either (meaning at the twelve month mark if (when) the caulk cracks it is your problem)

$6 a LF for almost 1200 LF of crown moulding (any crown moulding) furnished and installed almost sounds too cheap. I also agree that for anyone to judge a price without knowing all the particulars is dam near impossible............................

Wow small world Karen Rose! lol I am currently in Boynton so we are close! yes please, I would love the information to the person who did yours. Thank you

Houses in PNW rarely have crown molding. Even 1-2 , 5 min dollars, brand new or old rarely have crown moulding. I love it, so my husband made me a gift. We bought crown moulding from local yard- 65ea 16 ft pieces , it was a little bit over a dollar per linear feet for material. Than you need good tools, some experience and patience. 2k and 2 mo later it was done. I love it! There are certain tricks, but you can find online very good tutorials. Again I’ve seen houses on east cost , good mill work and a lot more fine details. Not really important at my area for a lot a people but it looks nice, so approx 1 dollar per linear feet can get you nice upgrade.

I have no idea but my thought was is this CAD or USD?

I would go with MDF, material is half the price of wood. It is soft and dents easily so I would not use for any trim but with crown it won't get dented. That should save allot on material costs and the carpenters that install it will love that it is very light working overhead and 'should' charge less for labor. Over $5.30/ft is 'insane'! Get several quotes.

I dont know why would someone even want entire house of that... Do you really want this in a bathroom? If you going for a certain look clean modern contemporary it will not match. We selectively applied ceiling treatments matching ceilings height. Not in a kids bedrooms or bathrooms. Saves a lot of money as well.

Simona Stafano Houses in PNW rarely have crown molding. That is interesting. We are in the PNW. After designing our house with crown molding in almost every room, once flooring and walls were up, we decided to eliminate crown molding in the entire home, molding for which I was planning to import since it would have been a huge quantity. In any case it is something I can do myself anytime. I got the hang of it several years ago; I prepaint the molding, cut then install, follow up with a minor touch up; examples below from my previous basement remodel I did.

Pinebaron-I love it! But the key is -you designed it, you installed it. Go to Zillow and see how many houses come with crown molding:) PNW - Seattle...Import moulding... I will say it is overkill ....unless you go in specific area and price range. But than again you said it is DYI , so it is overkill:)

"crown mounding quotes outside the building"

If that doesn't mean exterior crown molding, what does it mean?

Maybe it is a typo.

Outside of having the production builder include it in the initial build ("building" used as a verb).

OP wants to remodel upon taking ownership.

"Build", in all its forms, has become the most commonly misused word on the forum. Are words like project, construction and contract too difficult? The OP says the quote is like a foreign language to her but she's using jargon I can't understand.
