MONDAY MORNING MESSENGER

Message prepared especially for Members of the American Institute of Inspectors® as well as Home Inspectors abroad

May 7, 2001

GOOOOOD MORNING, A.I.I.™....

It's a great day here in Orem, Utah! Spring is here and the phone is ringing off the hook. Those of you that are lucky enough to have somebody else answering your phones should count your blessings. I have been shocked back to the reality of how hard it is to pull off a successful enterprise single handed.

Those of you that have your spouses to help you with the office details should take the time to re-appreciate how much they lighten your load. This is the perfect week to do this because it is only 5 more days to Mother's Day. For most of the readership this is the one holiday each year where the Mommy's of the household either gleam with pride, or they are left to feel the weight of under appreciation. So let's not miss this opportunity to show them how much we care. And for those of us with our Mothers still around let's not miss the opportunity to share with them our appreciation for all they have done to rear us and help us through the hard times.

 


METH LAB CLUES

What other Meth Lab clues are you aware of???

I haven't encountered any Meth Houses that I am aware of, but I once saw a rental that all the floors were removed and was growing POT, planted in the uncovered crawlspace. The house appeared normal from the outside. The shades were all closed, of course. I don't think it was located in the proper EFU Zoning for share cropping. Reggie Ayres - Medford, OR

CHIMNEY HAIRLINE CRACKS

Many of you know Bob Priesing from other Home Inspector forums. Bob hung up his Home Inspector shingle a year ago in favor of his Chimney Sweep shingle. Bob is an excellent resource for chimney and fireplace questions. Bob says that one of the most common questions is "What harm really are hairline cracks in the chimney flue tiles?" To put this subject to rest Bob has shared photos from a recent flue fire chimney reconstruction that revealed the long term results of hairline cracks.

This photo reveals a crack that appears to be nothing more than a line drawn with a pencil. In reality it is a hairline crack in a flue tile.
This photo shows The creosote buildup on the crack itself.
This photo shows creosote buildup in between the brick and the clay flue liner. When Bob was asked if that was really 1" of buildup behind the tile he said.... "Yes, you are seeing 1" of creosote behind the tiles. This was an extreme case. Every tile had multiple cracks, but none were actually missing pieces. We removed the entire flue liner by simply pushing the pieces away from the chimney wall with hand tools."

 

How much importance have you given to hairline cracks in the flue tiles???

CHIMNEY SWEEP INSPECTIONS

NFPA 211 deals with the issue of chimney evaluations. Back in 1999 Bob Priesing shared with me the standards that the Chimney Sweep Guild helped to set forth through the NFPA for varying levels of chimney evaluations. Since this is a potentially big ticket repair item for the homebuyer it is obvious that we, as Home Inspectors, do not have the ability to fully evaluate chimneys to the extent of a Level II. For this reason we would be foolish to retain the ultimate liability of the condition of chimneys when we have such a limited view of their actual condition. The following guidelines set forth the Level II Chimney evaluation as the one best designed for real estate transactions. If you are not disclaiming chimneys (after your limited visual evaluations of them), then you should get your E&O deductible ready for each and every home with a chimney.

Please note the guidelines for the Level II verses the Level I & III. The following information is excerpted and not reshared in its entirety.........

10-2 Annual Inspection. Chimneys, fireplaces, and vents shall be inspected at least once a year in accordance with the requirements of Section 11-3. Connectors, spark arrestors, cleanouts and tee fittings connected to chimneys and to oil and pellet venting systems shall be inspected at least one a year in accordance with the requirements of Section 11-3. Cleaning, maintenance, and repairs shall be done if necessary.

Exception: Type B and Type BW gas and special venting systems.

Chapter 11: Inspection of Existing Chimneys

11-1 General*. Where the need for an inspection of an existing chimney has been identified, the inspection shall be conducted in accordance with this chapter.

Exception*: Inspections which are incidental to a chimney maintenance or repair task not shown in Table 11-2 shall not be required to comply with the minimum levels of inspection set forth in this chapter. However, defects which are observed or observable during the course of such work shall be reported to the property owner or occupant.

11-2 Type of inspection. The scope of the inspection, the areas of the chimney examined, and the degree of invasiveness of the inspection shall be appropriate for the conditions giving rise to the inspection. The type of inspection shall be determined in accordance with Table 11-2.

11-2.1 The type of inspection performed shall be based on the circumstances which give rise to the inspection. For situations shown in the Circumstances row of Table 11-2, the minimum level of inspection shall be that indicated by column in which the situation is found. For situations not shown in the Circumstances row, the type of inspection shall be based on the descriptions in the Indications row.

11-2.2 Nothing shall prevent the examination of all or part of the chimney at a higher level than the minimum indicated by Table 11-2. Partial examination of the chimney at a higher level shall not require that the entire inspection be conducted at the higher level.

Now I realize that he preceding information is long and difficult to digest. The Reader's Digest version is that there are 3 clear cut levels of Chimney Evaluation. The level II is the one that is recommended during the sale of Real Estate. That does not mean that we are supposed to be the ones that are to do it, but that we should be recommending a Level II evaluation to our client's. I was amazed at the scope of the different evaluations..... Every time I sit through a chimney or wood stove training session I sit back and ponder all of the things about chimneys, flues, and stoves of which I am flueless, I mean clueless.

 

What is your current disclaimer for the scope of your chimney evaluations?

PHOTO CHALLENGE #56 FEEDBACK

Tired of typing with your stubby finger(s) on a small hand-held device? Exhausted from squinting at the smaller screens and key boards? Thinking about stepping up to a full size computer that you can use in the field? Then you are ready for Bubba's ergonomically designed transport system. Only $19.99. But wait! If you order within the next fifteen seconds we will throw in one additional roll of our fine Duct Tape.

I would buy it if shoulder pads were included for $19.99. Steve, does that include handling and shipping? PS. How much extension cord is included? R Ayres - Medford, OR

What's wrong with this arrangement? A few years ago I used one for 2 months, except that it was a lap top. It worked very well, but my posture has never been the same since. Richard Grisham - Las Vegas, NV

I like Bubba's full size computer package, and was ready to order it until I thought of how difficult it would be to maneuver in the crawlspace under a house. Sorry Bubba, but good luck anyway. Inspector's Name = Bill Craig OR City = Florence

I've seen little hoods that throw some shade on a notebook screen. Walter Jowers - TN

Introducing the Hoodman for just $39.95. This contraption fits over the laptop screen to cut the glare and allow a glarefree view of the screen...... It's a good idea, but what a pain to have to use. Why can't they make a laptop screen like a little Compaq iPaq with the sidelit easy to view on the exterior type screen???

http://www.hoodmanusa.com/computer_hoods.htm

--Eliminates glare .......--Allows for private viewing ......... --One size fits all ..... --Rugged spring loaded nylon hood pops into shape instantly.......... --Hood collapses quickly into its flat 8" travel bag e-clipse fits on Powerbooks, ibooks and 95% of the PC laptop market

 

I was looking for something just a bit more compact... I think I will wait for the following model. What a concept, though. How are sales going? Jim Corbin - Bow, WA

 

 


 

WHAT ARE SOME OF THE CHALLENGES IN YOU INSPECTION AREAS? 

Reggie Ayres took the time to share a major challenge found in his inspecting area. Reading his plight with shifting soils reinforces how difficult it can be to come into a new area and perform an inspection. I know that when I go to a new area I ask a lot more questions about the area. Has there been any reports of house movements, flooding, or high water tables? It is always revealing to ask this of the Listing or Selling Agents. Rarely do they expose any faults with the current property, but they will always educate you on other areas nearby. This information may help you in the future.

As an example of this type of questioning I found myself in Southern Utah inspecting a home for Shelly's parents when they moved up from Southern California. Their Agent was worthless with information about their subdivision, but he went on for ten minutes about a subdivision in the hills of Cedar City where the developer was warned about the instability of the soils. Undeterred he went ahead and built a neighborhood using what he thought was the sure fire way to stabilize the area, yet he failed miserably. These homes are now the kiss of death. Although the information was not helpful to me on that inspection, it will be very helpful when I once again to return to the area.

Now let's get on to Reggie's reality.......

Homes built on the East side of our valley ten or more years ago mostly do not have engineered foundations. The most prestigious sites have the poorest conditions for home construction. Conditions include; expansive clay soils, unstable soils, and near surface water migration. Paved roads leading up to this area show the condition very clearly with settling cracks and sink holes appearing constantly. Just recently have designers and builders (some) have been using cason pillars tied to the foundation footings to hold the structure from sliding or settling down the hillside. Many homes that I have inspected rest totally on these concrete legs. A few times I have seen as much as four inches of daylight between the bottom of a footing and the base rock it was poured upon originally.

In some cases I am sure that the house is also moving downhill but at a much slower and not so obvious rate. Reporting these conditions and challenges can be most difficult for home inspectors. Engineer reports cost thousands of dollars and basically say one fact, "YOUR HOME IS BUILT ON UNSTABLE SOIL." All the seasoned home inspectors in this area are very familiar with the conditions and the various symptoms that appear. These symptoms include but are no limited to wall cracking, foundation cracking, settling, siding buckling, door sticking, cabinets separating from walls, tile shower wall cracking,etc.. Concrete slab sections will actually move apart or separate at the expansion joints. There is lateral movement besides the typical settling. I tell folks that desire hillside homes to look on the West side areas where the soil is decomposed granite. I hardly ever see structural movement there.

Well Michael, I hope this bit of useless information helps with filling the MMM as you traverse the great Wyoming expanse on your way to locate that roof leak. LOL! Reggie Ayres - Medford, OR

What are some horror aspects to your inspecting area???

PHOTO CHALLENGE #57

 

The following photo is from a ready to be stucco covered home. It will be traditional stucco and the applicator was ticked off with my findings of his prep work. You are seeing a white vinyl window, head flashing, wire, felt paper and some pink foam. This is what we usually cannot see, and that is what is scary......

 

  Why is this window/stucco joint going to leak like a sieve?

QUOTABLE QUOTES: ".... "What harm really are hairline cracks in the chimney flue tiles?" Thoughts uttered by a previously flueless Home Inspector named Michael Leavitt - Ouch! I resemble that remark!
