Choosing Sides
One of the not-so-great things about working in the particular market that I do, is that because a lot of the homes out here in the 'burbs were constructed within the last 15 years or so, we see a lot of the faulty construction issues that were common during that period. The major one being LP siding.
Today I had the interesting experience of touring 2 homes in succession that had failing LP, and in both cases neither the sellers nor their agents were aware of it. One agent claimed that it couldn't be LP, because the house was built in 1988, and LP was only sold in 1994 - 1995. In fact, the product was sold and put on more than 800,000 houses nationwide between the period of 1985 - 1995. The earlier product, that is, pre-1992, was the most prone to failure, so in fact, this agent's house is a sitting duck, and he just doesn't know it yet! But, since the failure of the siding is plainly visible to the untrained eye (i.e., mine), I'm sure he will soon find out...
As a Realtor, it only takes one listing with LP siding for you to become something of an expert on the subject because it can be the cause of so much heartache for your sellers. Heaven help the naive seller and agent who go merrily traipsing along, assuming that because the LP "looks okay" to them, that all will be well. There are a lot of different stages of failure, and some are not immediately apparent. The process of breakdown begins with tiny cracks, and without vigilant maintenance of the LP, you may have these cracks which allow water to seep into the siding, and not even know it.
I think it usually pays to know what you may be looking at up front, so a pre-inspection of the property can be beneficial, and having been through it once, I would now recommend any seller with LP siding have this done. In some cases, I can visually determine if damage exists, but I can't as easily determine the extent of the damage...or "how bad is it really?"
That's a big distinction, depending on whether the moisture has penetrated behind the siding and into the actual structure. Is it a matter of replacing all siding on the house, or is it possible to paint, seal and caulk the siding to keep minor damage from progressing? A pre-inspection can help answer these questions, and will allow you to formulate a plan to deal with the problem. The way I look at it, you'll either end up paying for it up front, or in the form of a price reduction or failed sale when the problem is uncovered.
In Washington state, sellers are required to disclose if there is LP (or and fiber-board type siding) on their home, and if the siding has begun to fail, most lenders will not lend on the home. (Clearly, the agent mentioned above either didn't read his seller's disclosure, or maybe the sellers don't know either! ) This can make it extremely difficult to sell, even if the siding only has minor damage, simply because most buyers do not want to put themselves in the position of buying a home knowing that there is a $10K-$15K repair job that will have to be done...and with LP and a lot of similar siding products, it is not a question of IF it will need to be replaced, but when. So, if a homeowner has this siding, they will most likely end up having to make some sort of arrangements to deal with this problem.
I guess the long and short of it is, if you are a real estate agent or a homeowner whose home contains these products, it pays to educate yourself about the products, know your options and have a plan for dealing with any problems that may arise.
