 Quick Results, and is a simple way to link offline printed material to online content with the least effort.  

Imagine a potential buyer out gathering flyers on a Sunday afternoon. They see a QR code on your flyer or sign and scan it with their free QR reader app. It takes them straight to your virtual tour where you end with an invitation to show them the house – all while standing in the driveway!

Go to your phone right now and find a QR code reader, then scan the code above. It will link you to an online video from our website about clearing a slow sink drain (hey, we’re home inspectors, what do you want?). Think of all the places these can be used; post cards, flyers, and yard signs. Put it on your business card to link it to your Facebook page. There are even a companies that will print shirts and temporary tattoos.

History of the QR Code

QR-Codes first hit mainstream when they were initially used for tracking parts by vehicle manufacturers. After a while, companies began to see the scope for where QR-Codes could be used elsewhere within the world. The most commercial use for QR-Codes is in the telecommunications industry where the mobile phone seems to be the biggest driver of their popularity.

The codes have been around since the mid 1990’s in Japan, and then made their way to Europe. They are just starting to get used in the U.S. Advertisers use QR codes so that people can quickly scan an advertisement on a bus, a store window, or magazine ads and be taken directly to online content.

QR-Codes are capable of handling of sorts of data, including numbers, alphabetic characters, Kanji, Kana, Hiragana, symbols, binary, and control codes.

A total of 7,089 characters can be encoded in one symbol alone.

QR-Code Data Capacities

Stop, Look and Listen

Checking your own house periodically can prevent disasters

Home inspectors use all of their senses when inspecting a house. An experienced inspector can draw several conclusions within the first few minutes of a home inspection. Actually, as soon as we pull up to a house, we can pretty well determine what we are in for. Many of the problems we see and report on could have been avoided. Here are some things you can (and should) do periodically to maintain your house.

At least once every six months, take some time to care for your prized investment – your house. Pick a quiet time of the day when the kids are away, no gardeners are blowing leaves, and you have about half an hour of free time. Turn off the radio, iPod or TV. Quietly walk around the interior of your house and listen. Really listen for drips, leaking water, and running toilets.

One common source of leaks is in the toilet tank. If you hear running water it is usually caused by one of three things; a high water level, a

Brittle Flapper

Brittle Flapper

worn flapper, or a worn valve. The simplest problem is when the level of the water is set too high. You will see water pouring over the top of the spill tube. Adjust the float to shut the water off before the level goes over the top of this tube.

If you still hear water trickling at the toilet when the valve has stopped, your flapper valve may be worn out. Over time the flapper valve becomes brittle. It will no longer create a good seal and water trickles through. This constant flow of water can cause a lot of problems. It can deteriorate the wax seal under the toilet which leads to floor damage. It can also cost you money because tens or hundreds of gallons of water per month are going down the drain. One telltale sign of a worn flapper is “phantom-flushing”. That’s when your toilet mysteriously fills with water periodically by itself. Flappers are inexpensive and easy to replace. We recommend replacing all of them throughout the house at the same time.

If the water continues to flow after changing the flapper and adjusting the level, the valve itself may be bad or your water pressure is too high. Flush the toilet and observed the water flow. If it is spraying really hard, or if the valve whines when shutting off your pressure regulator may have failed. Call a plumber or buyer a pressure gauge (about $12) and have it checked. If the water pressure appears normal (50 – 80 psi max) then your toilet fill valve may be worn and requires replacement. Changing the toilet fill valve is fairly easy and a reasonable do-it-yourself project.

You’ll also want to listen for dripping tub and shower faucets. Again this wastes water, but it can also rust out components in the tub and

 drain. Fixing this might be beyond the average homeowner. So get a plumber to do it. It will save you money in the long run.

Your water heater can cause a lot of trouble particularly if it is more than 10 years old. If the water heater pops or gurgles when it is heating water, replace it. This indicates pending failure and poor efficiency. You are hearing sediment at the bottom of the tank. Over the years, sediment from the water and the rusting tank settles at the bottom. This layer of gunk acts as an insulating layer. When your water heater tries to heat water, the flame must stay on longer to heat the water. By the way, simply flushing your water heater once a year can prevent this.

To wrap up your plumbing inspection, check all of the valves under the sinks, at your clothes washer and behind the toilet. These valves

Corroded Valve

 commonly fail, and can flood your house. If you find valves that have excessive calcium build-up, have them replaced immediately. We recommend changing them all even if you find one that is deteriorated. The others will follow.

Another item that should be checked periodically is your electric panel. Now if you have any concerns about your electrical system you should not do this yourself. Rather, call an electrician. But if your electric panel is in good condition open the lid and listen for buzzing breakers. You can also gently rest your hand on the breakers to see if they are excessively hot. If either of these conditions

GFCI receptacle

exists you should have your panel checked.  Your GFCI receptacles must also be checked periodically. They have a built-in test button. Go ahead and test them. If they do not trip, or reset, they need to be replaced.

There are many other items that should be checked at your house including the roof, windows, garage door, heating and AC system, and appliances. Plumbing and electrical systems cause the most problems. Most home inspectors will provide a maintenance inspection for homeowners. It is a good idea to have your house inspected periodically. Catching some of these items early can save you money in the long run.

A must-read for anyone in real estate

While we are seeing an increase in “traditional” transactions, the majority of the houses we inspect lately are short sales or forclosures. So how did we get here? And what can we do about it?

My friend and Real Estate Broker Marian Anthony has published a book that answers all the questions surrounding the current real

 estate environment. In his book “Short Sale Rush” Marian goes through the history of what lead to the current real estate crash, what can be done to avoid a repeat, and what homeowners can do if they are faced with losing their home.

The book answers so many questions. There are chapters on Non-Performing Assets, Short Sale procedures and Hard Money Lending to name a few. And it has a great “frequently asked questions” chapter which answers many questions such as:

 

This book really is a must-read for anyone interested in real estate today.  Whether you are a homeowner facing

 

 the reality of short sale or forclosure, an agent who wants to help people sell or buy a short sale, or just someone who wants to cut through the “noise”, you need to read this book. It is a short 124 pages packed with information.  

I highly recommend this book for agents, homeowners, or anyone who wants to understand the current real estate environment. I learned stuff I never even considered!  It is available at www.amazon.com or read an excerpt at www.shortsalerush.com

Identifying Problem Roofs

Tuesday, May 4th, 2010

Asphalt Shingle Roof

A roof is one of the most expensive components of a home. Hundreds of different materials have been used as roofing material from sticks to plastic, and grass to glass. When you are looking for a home you need to know what type of roofing material is installed, if it was installed correctly, and the current condition. A thorough home inspection will include a detailed evaluation of the roof. A roof in poor condition can be a deal breaker, so here are some things to look for that can give you a heads-up about the condition of a roof.

The majority of the houses we inspect range in age from the 1950’s to new. The most common roof material we see in San Diego is the three-tab composite asphalt shingle roof. It is made of oil-impregnated fiberglass material, with an aggregate (which looks like kitty litter) pressed into the surface. The aggregate adds color, but its primary purpose is to protect the shingles from UV exposure. Once the aggregate is worn, the shingle deteriorates rather quickly. The majority of asphalt shingles have a life expectancy of 20 or 30 years.

Worn Asphalt Shingle

Worn Asphalt Shingle

Before making an offer on a house, take a close look at the roof. If you see worn areas, this indicates that the shingles are nearing the end of their life. You can also do some simple math to estimate the age of the roof. If you are looking at a house built in 1970, the house is 40 years old. Assuming that the house originally hadWorn Aggregate a 20-year asphalt roof, it was most likely replaced in the early 1990’s. That means that the current 20-year roof is nearing the end of its 20 year expected life.  

Look around the perimeter of the house for evidence that the aggregate is washing off of the roof. If you see piles of gritty material which is the same color as the roof, you’ll know that the roof is deteriorating.

 

Tile Roof

The other most common roof type in San Diego is the tile roof. Authentic Spanish tile roofs are made from baked clay, and the color is solid all the way through. These tiles will last a long time; 50 – 100 years if properly maintained.

A less expensive, but very durable material is the concrete tile. These tiles are more uniform, and are color coated concrete. These come in a variety of shapes and colors. Tiles can be flat, or curved to emulate Spanish tiles. These tiles should last 50 years, however some of these tiles were poorly made and will not last that long. You will notice that some tiles, which should be glazed, are now dull and often have moss or dark staining on them. Some roof contractors will recommend that you replace these tiles.

Prior to the 1990’s, many tile roofs were poorly installed without the metal flashings now common on tile roofs. On the older tile roofs, the bottom edge of the lower row of tiles was held up by a small board commonly called a

Fascia Detail

shadow board, so that the slope of the tile was consistent with those at the the upper rows. (On the upper rows, each tile rests on the top edge of the tile below it.)  Without a shadow board, the bottom row of tiles lay at an different angle than the remainder of the roof.

The tar paper was draped over the shadow board. Over time, the paper sagged causing water to “pond”. The standing water eventually damages the paper underlayment, which can cause damage to the wood under the paper, and the fascia. To make matters worse, the open end of arched tiles allows the sun to shine in on the paper. The UV rays caused the paper to dry out and shrink.  Once the

 paper deteriorates, water then pools behind the shadow board causing dry rot.

Newer tile roofs installed after the mid-1990’s were installed with a metal flashing at the bottom edge of the roof. This flashing serves several purposes, it holds the bottom row of tiles at the correct angle, it encloses the open end of arched tiles, and it acts as a drip edge to direct water away from the fascia board.

There is another important reason to “close” the ends of the tile. Wind driven fires proved devastating even for houses with tile roofs. That is because embers were blown up into the roof through the open ends of the tile. There the embers start roof fires which  are very difficult to extinguish. This flashing is often referred to as “bird stop” for its ability to keep birds from nesting under the tiles.

If you are purchasing a house that is 20 years old or more, take the time to look at the roof. You could save yourself a lot of heartache later.

What is an Arc Fault Circuit Interruptor?

Sunday, February 14th, 2010

Arc Fault Circuit Interrupters

Arc Fault Circuit Interrupters (AFCIs) are special types of electrical outlets and circuit breakers designed to detect and respond to potentially dangerous electrical arcs in home branch wiring.

How do they work?
 
AFCIs function by monitoring the electrical waveform and promptly opening (interrupting) the circuit they serve if they detect changes in the wave pattern that are characteristic of a dangerous arc. They also must be capable of distinguishing safe, normal arcs, such as those created when a switch is turned on or a plug is pulled from a receptacle, from arcs that can cause fires. An AFCI can detect, recognize, and respond to very small changes in wave pattern.

What is an arc?
 
When an electric current crosses an air gap from an energized component to a grounded component, it produces a glowing plasma discharge known as an arc. For example, a bolt of lightening is a very large, powerful arc that crosses an atmospheric gap from an electrically charged cloud to the ground or another cloud. Just as lightning can cause fires, arcs produced by domestic wiring are capable of producing high levels of heat that can ignite their surroundings and lead to structure fires.

According to statistics from the National Fire Protection Agency for the year 2005, electrical fires damaged approximately 20,900 homes, killed 500 people, and cost $862 million in property damage. Although short-circuits and overloads account for many of these fires, arcs are responsible for the majority and are undetectable by traditional (non-AFCI) circuit breakers.

Where are arcs likely to form?
 
Arcs can form where wires are improperly installed or when insulation becomes damaged. In older homes, wire insulation tends to crystallize as it ages, becoming brittle and prone to cracking and chipping. Damaged insulation exposes the current-carrying wire to its surroundings, increasing the chances that an arc may occur.

Situations in which arcs may be created:

  • electrical cords damaged by vacuum cleaners or trapped beneath furniture or doors.
  • damage to wire insulation from nails or screws driven through walls.
  • appliance cords damaged by heat, natural aging, kinking, impact or over-extension.
  • spillage of liquid.
  • loose connections in outlets, switches and light fixtures.
  • Rodents chewing on wire insulation
  • Cords pinched behind furninture or in doorways
Where are AFCIs required?
 
Locations in which AFCIs are required depend on the building codes adopted by their jurisdiction. Inspectors are responsible for knowing what building codes are used in the areas in which they inspect.

The 2006 International Residential Code (IRC) requires that AFCIs be installed within bedrooms in the following manner:

E3802.12 Arc-Fault Protection of Bedroom Outlets. All branch circuits that supply120-volt, single-phase, 15- and 20-amp outlets installed in bedrooms shall be protected by a combination-type or branch/feeder-type arc-fault circuit interrupter installed to provide protection of the entire branch circuit.

Exception: The location of the arc-fault circuit interrupter shall be permitted to be at other than the origination of the branch circuit, provided that:
  1. The arc-fault circuit interrupter is installed within 6 feet of the branch circuit overcurrent device as measured along the branch circuit conductors, and
  2. The circuit conductors between the branch circuit overcurrent device and the arc-fault circuit interrupter are installed in a metal raceway or a cable with metallic sheath.
The National Electrical Code (NEC) offers the following guidelines concerning AFCI placement within bedrooms:
Dwelling Units. All 120-volt, single phase, 15- and 20-ampere branch circuits supplying outlets installed in dwelling unit in family rooms, dining rooms, living rooms, parlors, libraries, dens, sun rooms, recreation rooms, closets, hallways, or similar rooms or areas shall be protected by a listed arc-fault circuit interrupter, combination-type installed to provide protection of the branch circuit.
Home inspectors should refrain from quoting exact code in their reports. A plaintiff’s attorney might suggest that code quotation means that the inspector was performing a code inspection and is therefore responsible for identifying all code violations in the home.  Some jurisdictions do not yet require their implementation in locations where they can be helpful.
 
What types of AFCIs are available?
 
The four most common types of AFCIs are as follows:
  • Branch/feeder—installed at the main electrical panel or sub-panel.
  • Outlet circuit—installed in a branch-circuit outlet.
  • Combination—complies with the requirements of both the branch/feeder and the outlet circuit AFCIs.
  • Cord—a plug-in device connected to the receptacle outlet.

Nuisance Tripping

 
An AFCI might activate in situations that are not dangerous and create needless power shortages. This can be particularly annoying when an AFCI stalls power to a freezer or refrigerator, allowing its contents to spoil. There are a few procedures an electrical contractor can perform in order to reduce potential “nuisance tripping,” such as:
  • Check that the load power wire, panel neutral wire and load neutral wire are properly connected.
  • Check wiring to ensure that there are no shared neutral connections.
  • Check the junction box and fixture connections to ensure that the neutral conductor contacts a grounded conductor.
Arc Faults vs. Ground Faults
 
It is important to distinguish AFCI devices from Ground Fault Circuit Interrupter (GFCI) devices. GFCIs detect ground faults, which occur when current leaks from a hot (ungrounded) conductor to a grounded object as a result of a short-circuit. This situation can be hazardous when a person unintentionally becomes the current’s path to the ground. GFCIs function by constantly monitoring the current flow between hot and neutral (grounding) conductors, and activate when they sense a difference of 5 milliamps or more. Thus, GFCIs are intended to prevent personal injury due to electric shock, while AFCIs prevent personal injury and property damage due to structure fires.
 
In summary, AFCIs are designed to detect small arcs of electricity before they have a chance to lead to a structure fire.
