Testing a Sump Pump

March 8th, 2010 by welmoed

The house you are considering has a sump pump, but does it work? You might be able to test it yourself fairly easily; if not, you may want to ask the seller to have it tested.

Obviously if the sump pipe is wet, or the ground around the outlet is wet, it has run recently. If the sump crock is open at the top, you can pour a bucket of water in and see if the pump starts up. If you can reach the float, you can raise it, and see if the motor starts running.

If the sump crock is SEALED, you may be able to test it anyway IF IT HAS TWO WIRES rather than just one.

The position of the float turns the pump on and off.

One wire is the float switch, the other goes to the pump itself. By unplugging the switch AND the pump and then plugging the pump directly into the outlet, the pump should come on.

Once you have verified that the pump is running, unplug it again and put it back the way you found it. Don’t let the pump run for more than a few seconds if the crock is dry; it could damage the pump.

More on Ice Dams

February 20th, 2010 by welmoed

Bob did an inspection shortly after the big snowstorm hit the DC area last week, and it provided a great opportunity to illustrate how poor insulation can cause big issues with ice dams.

Even though there were no indications of water intrusion in the interior of the house, it was obvious that there was ice damming going on.

Water from ice dams is seeping down the exterior wall

Water from ice dams is seeping down the exterior wall

Water has penetrated through the eaves on this house, and is seeping down the brick exterior, where it saturates the brick and refreezes. This can cause damage to the brickwork, shortening its life.

This bedroom had a cold spot in the corner.

The ice dam evidence outside prompted Bob to pull out his Thermal Imager. Taking thermal images is not part of a regular home inspection; in this case he was using it to find possible water damage inside. Although he didn’t find water damage, he did find some examples of why the house had ice dams.

The bedroom corner lacked any insulation

The thermal image revealed a joist space on an exterior wall without any insulation at all. This patch could allow warm air to escape into the attic space and cause the snow on the roof to melt from underneath.

Notice the snow has thinned between these two dormer windows.

Snow that melts unevenly can be a clue for where to look for missing insulation. Here, the space between these two dormer windows was a closet.

The roof over this closet had less snow than other areas.

Areas around the joists were not insulated properly

Areas around the joists were not insulated properly

Batts of insulation were compressed around trusses, leaving bare spots over some of the joist areas. The batts should have been cut to fit around the trusses. Also, whenever insulation is compressed, its R value is reduced.

You don’t necessarily need a thermal camera to find gaps in your insulation. All you need is a really cold day. Run your hand along the walls and ceilings, especially at the edges and corners. If one area feels cooler than the others, there’s a good chance it’s underinsulated.

Ice Dams: Prevention is the Key

February 17th, 2010 by welmoed

The Mid-Atlantic region had a “major snow event” last week, and one of the byproducts of all that snow has been a huge ice-dam problem.

How an ice dam works

How an ice dam works

Ice dams can happen any time snow falls on a sloped roof, especially if the gutters are clogged with debris and the attic is poorly insulated. Heat from the interior melts the underside of the snow pack; this water flows down the roof and is stopped by a buildup of ice at the edge. With nowhere to go, the water pools at the edge and rises under the shingles, where it then can flow down through the attic space and into the ceilings and walls of the house.

Heat from the house can get into the attic several ways.

Heat from the house can get into the attic several ways.

Houses with very shallow or non-existent eaves are more likely to experience ice dams, as the edge of the roof is directly above the heated living space. Also, if you have recessed ceiling lights, they may also allow heated air to leak into the attic.

Once you have ice dams, there’s not really much you can do about them.
After the snow melts, though, you will need to do several things to prevent them from happening again.

  • Insulate the attic, especially at the eaves. Any insulation that got wet from a leak must be removed and replaced. The best thing is to insulate the floor of the attic, so heat from the house doesn’t penetrate the attic. This will also reduce your heating bill. Keeping the attic cold during the winter will prevent the snow on the roof melting from the inside out.
  • Keep your gutters clean. Have them inspected and repaired, if necessary. Gutter helmets and other debris guards will not protect against ice dams.
  • Have a roofer install ice and water shield underneath the first few courses of shingles on your roof. This will create a waterproof layer of protection for the lower edge of the roof, so any accumulated water that gets under the shingles can’t penetrate to the sheathing.

Sorry, We Can’t Make It

February 10th, 2010 by welmoed

In order for us to do Home Inspections, it is first necessary for us to find our driveway.

Somewhere under all that snow is a driveway.

Somewhere under all that snow is a driveway.

We got 22 inches of snow over the weekend, and are now poised to get another foot on top of that. The local, state and federal governments have ground to a halt; roads are impassable, and everyone is urged to stay home.

Many of our clients with Home Inspection contingencies written into their contracts are asking for, and receiving, extensions on those contracts. If you are facing a contingency deadline, contact your agent and ask for an extension.

Safety is our main concern when scheduling inspections during weather emergencies. Therefore, we have postponed all inspections until next week.

Remodeling Perils and Pitfalls

February 9th, 2010 by welmoed

We often get calls from people asking if we can inspect their basement remodeling job because they have concerns. The answer is yes, we do perform remodeling inspections on a consulting basis, and have also been called to provide expert testimony in remodeling lawsuits. However, the best way to avoid the worst remodeling nightmares is to be fully informed about the process, and to carefully select who does the work.

Here are some suggestions to help you get through your remodeling project BEFORE you call us with concerns.

  1. A quality remodeling contractor should not ask you for more than a small deposit when you sign your contract, and will go to great lengths to explain your rights under both state and local laws, including any special jurisdictions’ additions. If a contractor demands a large up-front deposit, it could be a red flag: perhaps they don’t have adequate credit with their suppliers.
  2. A written contract is a must. The contract should specify the scope of work, the start and end date, the cost and payment schedule, and who will be performing the work.
  3. Ask for a copy of their license and proof of insurance. Check the license and ask that their insurance carrier MAIL you a cover page showing you as an insured.
  4. Make sure they are licensed for the work they are performing. A general contractor’s license is not an electrician’s or plumber’s license. Also, make sure the license is current; check with your state licensing authority.
  5. Check with the Better Business Bureau to see if there are past complaints about the company. You can also check on Angie’s List, or do a web search using the company’s name.
  6. Are they in permanently marked vehicles and using printed letterhead? Magnetic signs and “stock” contracts from the stationery store are not good indicators.
  7. Almost all but the smallest remodeling projects will require permits. Adding lights, outlets, switches and almost any plumbing work requires permits. If your contractor either says he can do it without permits, or wants YOU to pull the permits, you should seriously question why. Permits are to protect you. If you pull the permits, you are the responsible party, not the contractor. The person doing the work, or supervising it, should pull the permits.
  8. Work sites need to be clean, neat and orderly at the end of each and every work day. Messy worksites are dangerous to both you and the contractor’s workers.
  9. Don’t give final payment until ALL permits have been completed, finalled or otherwise acceptably closed and you have the paperwork in hand. Some of the best contractors will say that the last payment is due some period AFTER they have completed all of the work.

What can we inspect for you?

  • We SHOULD only be inspecting fit & finish as the electrical, plumbing and Heating/Cooling SHOULD be inspected by the local authority as part of the permit process.
  • We can only inspect what we can SEE. If the drywall is already installed, we can’t see the components.
  • We prefer to do “pre-drywall Inspections” when almost all of the infrastructure has been completed but the walls are not yet closed up. At this time we can see all the plumbing, electrical, insulation and ventilation components and take the time to inspect them carefully, possibly seeing things that the permit inspector missed due to constraints on his time.
  • We are happy to review ideas and plans as consultants, pointing out the things we have seen become problems in other (including our own) remodeling projects.

What Will Happen to Your House?

February 2nd, 2010 by welmoed

The History Channel has an excellent series called “Life After People.” There’s a new episode airing tonight that should be of particular interest to homeowners: “Home Wrecked Homes”.

From the HistoryChannel.com website:

Examine the apocalyptic fate of every home in the world. Gas leaks turn suburbs into infernos; a famous castle is toppled by a hidden flaw. Paint causes some high-end homes to explode in flames. Houses fall from the world tallest apartments to the most crowded complexes.

We’ve written before about what happens to houses that aren’t maintained properly, or that have their utilities shut off. It will be interesting to see how this is portrayed in this program!

Save 13%-70% on your Cooling Bill!

February 2nd, 2010 by Inspector Bob

The Standard Seasonal Efficiency Ratio  (SEER) for Air conditioners only ten years ago was around 10-13.  A top of the line central air conditioner can now hit a SEER of 21, for a Potential savings of 38%. If your unit was not maintained properly, or was an even a lower SEER unit, your savings could be even more.  The savings for heat pumps are similar, but heat pumps don’t have quite as high a SEER as air conditioners, but they also started out lower.  The changes in heating performance are nice, but nowhere as great as the cooling.  Those with gas heating and electric air-conditioning will see the greatest savings in the summer.

Other advances

Multispeed indoor AND outdoor units are much quieter and save more money by matching the compressor and fan speeds to actual need. Additionally they also control humidity much better than single speed units.

There are also better filters (We like the 4” pleated) that work better but do not need to be changed every month and don’t generate Ozone like some of the Electrostatic unit.  UV Lamps in duct work serve to sterilize mold spores and pollen, further reducing potential allergens.

Modern thermostats are now typically programmable for setbacks during off periods and can even cope with larger setbacks without invoking the dreaded Heat-Pump Auxiliary Heat.

Compare the SEER ratings to calculate your energy savings.

Compare the SEER ratings to calculate your energy savings.

How much you will actually save will depend on how you live, your thermostat settings,  the age of your equipment and more, but from the chart at left, you can see that the potential savings can be substantial.

As little as 8 years ago, SEER 8 units were still being sold and installed because they were cheap. It was only in 2006 that a minimum allowable SEER was mandated, and that was only 13.

Want to get an idea of what you might save? Take your HIGHEST electric bill and subtract your LOWEST. What is left typically represents your highest cooling cost. Then multiply by the appropriate factor from the table. You may not get that savings every month, but it gets the point across.

Last year, we had our furnace and heat pump units replaced, even though they were just ten years old. Since then, we’ve seen between 30%-50% drops in our electric bills. At this rate, the new system will have paid for itself within five years. Not a bad return on our investment!

Coming Up Next

There have been big changes in Refrigerator and Freezer efficiencies. You may want to unplug that old freezer in the basement after reading what we have learned! Look for that article soon!

Inspecting Challenges: “Winterized” Homes

January 27th, 2010 by welmoed

Many vacant homes in foreclosure or bank-owned are “winterized”, meaning the utilities are shut off. Prospective buyers will ask whether Bob can inspect such a house. The answer is generally “Yes, but why would you want him to?”

Bob can inspect the house, but many of the systems NORMALLY inspected as part of the inspection will need to be “disclaimed” or not inspected. This means Bob can look at items, but cannot tell whether they work. The stove/furnace/water heater may look fine, but without utilities, there is no way to know whether they work, or leak, or are unsafe.

If the gas is off

  • Can’t test gas furnace, water heater or stove
  • Can’t test gas fireplace inserts
  • Can’t detect gas leaks

If the water is off

  • Can’t test faucets, showers, toilets or tub
  • Can’t test water heater
  • Can’t test dishwasher
  • Can’t detect leaks in pipes or drains
  • Can’t test hose connections

If the electricity is off

  • Can’t test lights, outlets or switches
  • Can’t test GFCI (anti-shock) devices
  • Can’t test garbage disposal, electric ranges or ovens
  • Can’t test heat pumps

Winterized Houses Are Vulnerable
Modern houses are not designed to be kept out of their “comfort” temperatures. Houses that are allowed to swing wildly in temperature (and humidity) will have many more nail pops, drywall cracks, creaking floors and other symptoms, and may never completely recover. Cold and dry causes some issues, but HOT and WET can allow many other organic pests to invade and grow when humidity goes unchecked. As basements typically are cooler in the summer, unchecked humidity can cause natural condensation on basement surfaces, even IN and BEHIND walls where a typical visual home inspection won’t uncover them. Wood destroying organisms of the 6 legged variety love damp warm wood.

In addition, there’s the possible discomfort of trying to inspect a house with no heat during the colder months. Recently Bob was asked to inspect a vacant house that was SUPPOSED to have all the utilities on. When he got there it was 50 degrees OUTSIDE and 40 degrees INSIDE. The water and electricity had been turned on, but the gas had not and a hard deep freeze was in the forecast. He opened the house up to warm it to 50 degrees and told the selling agent to go buy some electric heaters to keep the house (and the water pipes) from freezing that night. Everyone wore their heavy coats during the inspection, including the client’s 1-year-old child who had to occasionally go spend time in the car with a parent to stay warm.

A Cautionary Tale
A few weeks ago, Bob scheduled a Home Inspection on a foreclosed house. The house had been “winterized”, and the inspection ended up being rescheduled four times, as each time the inspection date rolled around, the house was still awaiting “dewinterizing”. Finally, the realtor was assured that the house was ready. Bob drove up and saw a problem right away.

Water coming from under a garage door is not a good sign.

Water coming from under a garage door is not a good sign.

Even before he got into the house, he knew there were going to be BIG problems inside.

Water gushing from a disconnected pipe under the deck

Once inside, Bob found that many of the faucets were turned on, gushing water into tubs and sinks. The shower in the Master Bath had been turned on, and the head was pointing out the open shower door, leaving standing water in the master bathroom, damaged drywall, and soaked wood throughout the house.

Water dripping from the garage ceiling

The water from the Master Bath seeped throughout the house, including the ductwork in the garage. See the water dripping from the bowed insulation?

Water from the Master Bath damaged the ceiling of the first floor bathroom.

Water from the Master Bath damaged the ceiling of the first floor bathroom.

How did this happen? When the house was “winterized”, the faucets were opened to facilitate draining the pipes. The crew that came to “dewinterize” did not examine the house at all; they merely turned the water back on and left immediately. As a result, the water was left running for nearly a full day before Bob and his client arrived. The result? Probably several thousand dollars in repairs. If the water issues are not addressed quickly, the costs could quickly escalate.

The Bottom Line
If YOU are Winterizing a house, keep the heat/cooling on and set it for 55/85 as this will reduce costs while still keeping the HOUSE within its limits. If you stray too much outside this range, you are risking cosmetic damage at a minimum. Make sure you keep a close eye on the property, and walk through the house frequently to spot problems like leaks.

If you are BUYING a winterized home, INSIST that it be de-winterized for the Home Inspection.  If the ONLY thing stopping a possible sale is the Home Inspection, the seller should agree. De-winterization may uncover more than broken appliances and pipes, as the utility companies may want back bills paid before they turn the utilities back on, and these bills could come as a surprise later. Yes, they are supposed to be caught at closing, but sometimes they do get missed and then the buyer is left to pay them or face a protracted battle to get additional money from the (now gone) seller or remote mortgage holder.

Las Vegas in a Nutshell

January 25th, 2010 by welmoed

When you go to a conference, you get a lot of information. It comes in the form of brochures, fliers, DVDs, CDs, booklets and samples. And then there is all the other stuff: promotional items (affectionately known as “swag”), and, thankfully, bags to carry it all in.

So how much did we bring back from Las Vegas? Take a look:
