Help: wood is cupped is it installer problem?

12 years ago

I am having an issue with my 4" Somerset maple floor and am looking for any advice on where to proceed from here. Long story short, the flooring is cupping pretty badly, splitting in some areas. In an effort to rectify the problem, we have installed a dehumidifier and fans in the crawl space. Our home is new construction and there was probably quite a bit of moisture under there since much of the water drained under the house prior to the installation of the gutters. Indeed, it remains wet in one corner of the house, about 10 feet from the subfloor (it is a tall crawl space). Anyway, the humidity has been around 60% for a month now and the floors are no better. We had a rep from the distributor come to our house yesterday and he said that the subfloor is at 14% moisture. So, we know the crawl space is humid and are working to fix it. Here's the question. This floor was installed in June '11. It probably was wet under there at the time of installation and although the contractor had spread some plastic but not 100% of the area was covered. Here is the kicker...there was not vapor barrier put under the hardwood floor and the installer admits that he did not take any moisture readings at the time of installation. We think our floors might not be in such a shape had the installation been done properly. I don't want to take somebody to court because I certainly hope that we can take care of it by other means. However, I'm afraid that I will at least have to threaten court for them to do something. Opinions? Experiences with this? I'm thinking that without a vapor barrier, we will always have issues with the floor cupping (even if it goes down this winter) simply because I live in Kentucky and the summers are very humid.

It would have been nice if the installer took an extra step to look for moisture issues, but it's not something I would expect from an average installer.

There are companies that do an excellent job at sealing the entire crawlspace, not just throwing some plastic on the ground. Check out the photos on this page.

(I'm not endorsing this company, it's just an example.)

You might get lucky and have the wood return to normal after some time with a dehumidifier in the crawlspace. But it sounds like you already have some damage from splitting.

If the installer did not take moisture readings, he is not an installer! An average installer takes the readings as it is a vital part of installation. Acclimation is probably the most critical step of any install. My company takes moisture readings and documents them for the consumer and the installation team. Never an exception or people are terminated. That is how critical it is!

There are a couple of ways you can break this up, most of which depend on the skill of your installer. A recent post on my blog explains building a foyer like area to do just that in the entry way of a townhouse to prevent a hallway from having a bowling alley like feel. Basically you build a picture frame like outside with 2-3 boards for a border, then fill the interior with a design of your choice. This is one of many techniques that can help with this type of transition. Here is a like to my post about it so you can look at the drawings I built to demonstrate this concept. http://www.ifloor.com/flooringexpert/2007/07/decorating_with_bruce_turlingt.html Should you have any other question feel free to get in touch with me. flooringexpert@ifloor.com Here is a link that might be useful: Ask the Flooring Expert Blog

Help! Wood Stove clearance install problem
Q

Don't entertain that thought anymore. That is a bad idea a customer came into the showroom one day In search of an insert. I was going to sell him one until I found out he was doing exactly what you are doing. Taking a manufactured fireplace out and installing the insert. I told him no that's a bad idea don't do it, I won't sell you a unit. He went 15 miles down the road and bought one anyways. First fire he caused 42,000$ in damage to his house. If your going to do this check into a Kozy heat. They are specifically designed for a 0 clearance installation. http://www.kozyheat.com As far as the flue goes be sure to use a class A chimney. I recommend superpro21 they have a ceramic packed insulation between the inner and outer pipe allowing the pipe to expand and contract between the walls in case of a flue fire. Some company's have a packed insulation made of a cinder or clinker type material in the event of a flue fire the pipe will expand against the clinkers and damage the inside of the pipe. If your going to install a kozy heat or any zero clearance fireplace insert be sure to get the chimney cleaned annually. Wood inserts are a completely different ballgame compared to a fireplace. You will load it up and knock the air control back so it will burn a long time. In the mornings when you add more wood get the flue gases up to around 900 degreese for 20 minutes or so while your drinking your coffee. Then close it down. What your doing is taking the creosote from the night before and evaporating the moisture out of it. the creosote will dry up, flake off and land on the baffle. I have customers that take my advice and some that do not. The ones that don't I clean the chimney every year the ones that do I only see every few years. hope this helps

Problem with defective engineered wood causing delay in installation.
Q
Comments (3)
2 weeks is a miniscule delay in the world of construction, and manufactures warranties never include ancillary costs. Just replacement materials. Be glad that your installer didn't install the product, or it would be 10x worse!. Rent a couple of hotel rooms at a place that has complementary gathering rooms, have your party, and don't sweat it. Invite the installers for a couple of beers. It's not their fault that you scheduled your project too under the gun to make it happen. And they do feel bad about disappointing you by drawing your attention to the defects. But, they did the professional thing, and you owe them for that. Many would have installed garbage, collected their check, and disappeared.

Wood floor install - cupping!?! Does this look right?
Q
Comments (24)
Cupping is caused my moisture differences between the top and bottom of a wood floor. Without air conditioning the amount of difference is more limited. Newer finishes do a good job of protecting the wood from water and wear but they can also trap moisture or at least slow the migration quite significantly. Older finishes did not. Since they didn't seal the wood as well, moisture migrated through more readily, eliminating drastic differences between the tops and bottoms of boards. Houses weren't sealed as well as today so moisture that accumulated for whatever reason had somewhere to go. Standards are quite high today also. A sand job with some chatter mark wasn't cause for a re-do 30 years ago. When a floor isn't as smooth and flat as it can be made today, minor flaws are less noticeable. In the past things often took longer to build. The slower build allowed floors to acclimate more thoroughly before occupation. I'm in south Florida and I occasionally get people who claim you can't do wood here yet most of the little houses in the neighborhood near my office had wood floor installed when they were new, and none had air conditioning. It generally works fine until someone fixes a house up, puts in efficient windows and central air, then they wonder why their floor is cupping.

If you have water in a crawl space get that rectified as fast as you can.

It may take months for the flooring to dry out.

All the acclimation in the world is not going to help a wet crawlspace pouring water vapor into the house and floor.

The moisture readings would have indicated that a major problem exists!

Thanks for all of the helpful responses. Don't forget that he did not lay a moisture retarder either. I think that it is safe to say our installer is at fault for this situation. What can we expect from here? Should he replace the floor? Can we take action against him?

Tad it isn't recommended to put a vapor barrier between the floor and subfloor in a crawlspace installation. Reason being is if there is humidity beneath the crawlspace then the subfloor is going to expand and move the wood floor in a panelized effect anyway. The vapor barrier should go on top of the ground under the crawlspace. It should cover 100% and it should be black plastic not clear. Black plastic keeps any vegetation from growing under the barrier. Get that covered and keep running the dehum unit until it is bone dry under there. Only after it is dry and you've given the wood floor 2-3 months to relax can you attempt a fix. Anything prior to that and you could cause additional problems. Call me if you want to go over it.

"Don't forget that he did not lay a moisture retarder either."

Not advised anyway.

"I think that it is safe to say our installer is at fault for this situation."

"Indeed, it remains wet in one corner of the house"

I think you are just as much at fault for not having a dry crawl space.

"What can we expect from here? Should he replace the floor? Can we take action against him?"

Anyone can sue anyone.

You would not have been any happier if he had refused to even lay the floor until you fixed your wet crawl space.

Brickeye..I agree with you. I recently had a customer tear out carpet in preparation for the Hardwood Install. When we went to take acclimation reading, we found that the sub floor was particle board. We stated we can not lay over the particle board and the customer want to sue us? You can not win in today's consumer volatile hostile temperament. They get mad at you when you protect them and then they get madder when you do not!

The installer, did not communicate with the builder, and most importantly he did not own a good accurate wood moisture meter
