Thank you, byron, I was trying to answer someone who looked to the gubermint for truth. So I used gubermint sources. justaguy, if you dislike the organic vs. synthetic distinction, let me make it more clear -- untested-and-new-chemicals vs. millions-of-years-old chemicals. Good ol' Captain Kirk mixed a couple of chemicals together to make gunpowder in a rock, that's been a known combination for hundreds of years. Most of the other combinations are known too. But what happens when we combine Glyphosate with anything else? How about humans? We're just learning about those results. What about gene splicing -- what happens with that? What about the stuff they're spraying on your potatoes? How much testing has been done on that? Yes, natural chemicals and toxins are bad. So is too much water. We know what those things do. What about the new things that we're adding and spraying and eating? We have no clue. That is why I will not use synthetic chemicals in my garden, because I'd like to know what the hell they do before I get stage two liver cancer, and my spouse's carcinoma has metastacized to the lymphatic system. There are solutions to hand. In my mind, it's better to use them than to reach for something that has unknown results. striped cucumber beetles = less beans striped cucumber beetles + hand picking = labor + more beans striped cucumber beetles + safers = more beans + residue striped cucumber beetles + DDT = max beans + unknowns Just this once, I think I'll stay away from the lazy path, no matter what Ruth says.

Treated lumber is toxic! It contains large amount of arsenic and heavy metals (chromium) such as copper. I don't know what you think is "iffy" about this stuff being bad for you. It won't make you drop dead in one season but chronic exposure to these chemicals will effect your health in an adverse way. There are lots of articles on CCA (chromated copper arsenate) treated wood. Think of the following most of this stuff is coming from overseas now, where quality control might not be as concisions as it should be. Also this industry is worth billions of dollars and as you know big business hates bad press. Why trust a bunch of people out to just make a buck, they don't care much about you slowly poison yourself. Look at asbestos if you belief the press when it was popular it was like mothers milk. If you think the scientific research is still out on this subject you are naïve. Read a little between the lines and they say that these chemicals donÂt leach very far (which means they are not held in the material like they are supposed to be), and plants take up everything that is in the soil. They say organic & inorganic arsenic are in everything and the FDA gives safe level as 40ppm. However, al the studies I have seen donÂt focus on large amounts of chromium & copper poisoning which we know is bad for you. Hey this stuff is fine around the flower beds, as long as you donÂt compost it and move it to you vegetables the next year. Hey the day I see the these scientists and industry moguls growing there own food in planted made of this stuff and feeding it to their children & grand kids IÂll think about doing the same. No body is willing to say sure go a head it's safe they only give you conditions and try to chaing the subject. Why take a risk with your health? Hey if a termite wonÂt eat this stuff or a mold wonÂt grow on it why should I put this stuff in my body? Think about this, it may save you a lot of pain in the long run. There is an alternative now ACQ®, which stands for alkaline copper quat. Also Trex looks okay, but what's wrong with redoing you beds every few years. CloneZero

Yo Ken, if your still around your up on this one. Far as Composites go I am with the Larry/whoever We are for the most part. Composites are really no longer using recycled material because there is just not enough of it so most of the raw stuff is virgin,the energy used to make composite is an enviro no no, when its time to remove the project composite is not real big on bio degrade its tricky to burn shreading it would be silly. Bottom line composites are not so enviro freindly. Info like that might suggest its not all that good to clean it either, with anything. I dont agree>> composites will out last Ipe, left to go silver/gray Ipe is as close to no maintance as a person can get. With the softer composites like Choice/MoistureShield even trex= tjunk I have found a coat or two of TWP 116 seals up the decking,locks in the color and keeps mold,mildew,stains from causing major problems. Of course not needing to do this is the reason the Wallet goes for composite in the first place. I my own self dont like composites at all for the reasons stated in several posts here and on other sites. Welcome aboard Larry!!! Sorry I dident understand your intent at the begining . John

"We have decided to pay for the remediation of the mold ourselves, but I was surprised that there are no regulations about using dry wood". Since you have already taken action to have mold remediation performed, you have wisely decided your health is more important than other concerns in this situation. If you spent an enormous amount of money for mold remediation and health treatment, you may wish to consult your attorney to see if the framer is liable to reimburse you for these costs. The remaining long post below is for others who wonder what is all this hype about mold. I am a licenced contractor who deals with mold issues in connection with water intrusion damage to homes. In my years dealing with mold problems, I have come to understand mold from a different point of view than the average contractor or homeowner. To start, some background about mold. Mold is any of the thousands of kinds of fungus which inhabit the earth. Most mold is parasitic, and feeds off wood or vegetable matter that is found in nature. For various kinds of mold, there are different environmental conditions that promote their growth and survival. We usually associate warm, damp conditions with mold, but mold can live in many conditions from very wet to nearly dry, cold or warm. As partr of their reproductive cycle, molds create spores which are released into the air and settle on new surfaces where they can grow as new molds if conditions are favorable. Mold spores are microscopic spheres which can become airborne. But these airborne spheres usually have a coating on thier surface consisting of myotoxins -- (poisons that can cause allergic reactions or severe health problems when inhaled, or adhered to your skin). However, some mold spores are more toxic than others, and some people are more sensitive to these myotoxins than other people are. So we see a vast variation when we read reports from different people that mold is a health problem. Also note that theses mold spores are in the air even when there is no known mold that can be seen growing nearby. Mold spores are as common as dust in the air. Most people are acclimated to the normal levels of mold spores that are suspended in the air that they breathe. But if there are places that have a heavy mold growths, we often hear complaints from people that they can smell the mold, or they are experiencing allergic reactions. Perhaps I am one of the lucky people who is more resistant. I have been in areas with heavy mold growth which have caused homeowners to move out of their home because of their severe reactions, without returning until our crews removed the contaminated materials and treated the mold. On the other hand, I have seen most of the mold testing usually shows that penicillin is one of the most common molds found in most homes. This is known to be a kind of mold that is used as a medicine to fight bacterial infections. Because of the undefined health risks of mold, there have been no laws that specifically determined what levels of mold are acceptable, or what methods must be used to treat the mold to make a home safe and habitable. It seems to be more of a personal choice for each indiviual to determine what is acceptable or not. But there are certain established methods of mold abatement which are accepted in the industry. Before we get into the mold abatement methods, let's take a look at the other side of mold problems with wood. Some kinds of mold can attack the wood in a manner that makes the wood weak, so it does not serve its function as a structural member. But other kinds of mold are relatively harmless to wood or to people who are near the mold. As an example, some new lumber at the lumber yard has a spotty black coating on the surface when you buy it. These black spots are mold, which is usually found on "green lumber" which may feel wet or damp to the touch. But they are not generally harmful to the wood structure, because they are only growing on the surface, and they usually stop growing after the wood is nailed in place and has a chance to dry out. But if wood is stacked so it does not dry, then other kinds of mold can grow which appear often as white webbed strands on the surface, that can weaken the wood so badly that you can break it by stomping on a board. This usually takes some time for mold to penetrate that deep into the wood, so it is rarely seen home construction because the construction wood has a chance to dry from the time it is nailed in place. A second kind of mold damage to wood is seen in exterior wood that is exposed to the weather, especially in decks and in outdoor patio covers and trellises. It is usually called dryrot, but it is actually a mold which grows in wet conditions. The dryrot mold grows when the wood is drying after becoming wet. The mold likes the damp wood fibers, and will penetrate into the interior of beams and deck planks, especially in corners and seams where water is trapped so it cannot dry quickly. Dryrot mold can destroy the fiber strength so it is so soft that you can push your finger into the surface of a board. This is the reason why deck planks are usually spaced at least 1/4 inch apart, so the water can drain, and air can dry the space between planks. So we see there are two problems with mold -- a health problem and a structural problem. The structural problem can be solved by replacing the contaminated wood members. But if the wood has not lost its strength (no soft spots), then there is no reason to replace it. You can simply kill the mold so it cannot spread, then take precautions so new mold will not grow on the wood. How to remediate mold that is causing health problems? For the health problems, the usual method is to first remove all the mold from the surfaces that you can find. Then kill the mold with a fungicide. Ordingary bleach (sodium hypochlorite) will do this (You can also buy a commercial fungicide to kill the mold instead of using bleach). Dilute your bleach with half water or use your fungicide and spray all the surfaces that were contaminated, where you removed the mold from. Be sure to scrub the surfaces with a green kitchen scrubber or brushes soaked in the bleach solution. Then after everything dries for a day or two, paint it with primer paint like Kilz to encapsulate any microscopic mold spores that may be remaining on the surface. The primer will coat these remaining spores so they cannot escape into the air where you can breathe them. Note: These mold spores still contain the myotoxins even after you use the bleach or fungicide to kill the mold, so they are still a health threat. If you are sensitive to mold, then be sure to wear a mask with a filter so you don't breath the spores while you are working. Also wear rubber gloves, and even tyvex overalls taped at the wrists and feet to keep the spores from getting on your clothes. You can throw the overalls and gloves away when you are done with the mold abatement. This is the general procedure that people pay thousands of dollars to hire a professional mold abatement company to perform. About the particular problem of mold from the porch header circulating through the house, here are my thoughts: Generally speaking, there is no code that specifies when a piece of lumber has too much mold on it to be used for construction. There may be some local codes, but I can not imagine how they could specify the exact dividing line where the amount of mold or type of mold is acceptable or not. Ususally, if there is an ugly mold growth, a framer will discard the contaminated lumber and replace it. But this seems to be a judgment call by the framer. From the scenario above, I have visions of a framer who was thinking that its a whole lot of trouble to dig that header out and replace it, so it is good enough to leave it be. If the mold was really bad, the building inspector could tell a framer that the wood he used is not in good enough condition to pass the inspection, and require that he must replace it. I have never seen this done, but then I have never seen a framer use lumber that had mold actively growing on the lumber that he used for his remodeling other than that black spotty mold we often see on new lumber. If your building inspector has no problem with the header, then the only remaining objection is the objection that you raise. Your concern may be that you simply don't like the idea of using moldy wood to enclose inside your home -- (an objection which I agree with). Or maybe someone in your home is having health problems because of the increased mold spore levels inside the home. In any case, this is a problem you need to address with your framer, because there are no laws I know of that require him to remove it. It is best to specify that all the moldy wood is to be removed before any work starts, and have the cost of remodeling include this work. Otherwise, you are dealing with problems that could have been solved in the beginning instead of later. Some other notes about remodeling and mold: The mold from new lumber is not as toxic as some varieties which grow when persistent water is leaking onto surfaces in your home. Any surface mold on the studs is contained within the walls, and will stop growing when the wood has fully dried (less than 90 days). I doubt any of the spores will find a reason to move from the surface of the lumber past the drywall or to the ductwork where they can migrate to the interior of the home. During the remodeling, there may be higher levels than normal for mold spores and dust levels. But this will subside to normal levels after the construction is done. Unless someone in the home is super-sensitive to the surface mold that sometimes is found on new lumber, it does not seem like it will be a problem after the construction is done. You can take precautions if you are concerned, such as special air filters fitted to the furnace or even an electtrostatic collector to remove tiny particles suspended in the air stream. To answer the question: Is the framer required to use new lumber instead of lumber that was weathered outdoor for years? Probably not. It depends on local codes and what your local building inspectors will accept. Hopefully your framer will replace old weathered lumber it to keep you as a happy client and reference for future work he does.
