Properly Sealing Ductwork

Not something we talk about at parties, but the fact is leaky ducts are a common problem and a major source of energy loss in a lot of homes.  Homeowners pay dearly to heat and cool their homes.  The air traveling through their home’s forced air delivery system is sometimes partially lost by way of loose connections in the ductwork system.  Unfortunately in many homes a significant amount of that air may escape through duct leaks before it ever reaches the living space.

Finding duct air leaks and then fixing them (as opposed to replacing every duct run in your home) has been an ongoing challenge for the HVAC industry.  First, you can’t fix a leak if you can’t see it, and even if you can, slapping some duct tape on has proved an imperfect and temporary solution.  Never use duct tape on ducts; a UL 101 metalic or similiar tape is always preferred.  Even small holes when added up throughout the system can account for a huge loss of efficiency. The EPA estimates that 10-15% of air volume is lost as it travels through leaky ducts, in homes and in commercial/industrial buildings.

Here’s a  good video regarding the correct sealing process of ducts:

Post is Undersized

During a recent home inspection in Somerset, New Jersey, I noticed that a temporary hollow post was installed beneath and supporting a Steel I-beam located in the basement. As standard procedure, whenever a large beam is installed whether it be a built up wooden beam or steel I-beam, a solid steel concrete filled post is placed as support for the structural beam.

If you ask me, I think the hollow steel post had been put in temporarily and forgotten about; the hollow post is not rated to for such a heavy load as a house structure.  These steel I-beams were not connected together in anyway. Luckily it appears that the existing concrete posts were installed over solid concrete footings. Since the only thing that is needed is an additional post, the existing footing will be sufficient.  I always advise to install (4) four inch solid steel concrete posts under all types of beams.

I’m wondering how the Somerset County, NJ municipal code official missed this? Quite obvious during the rough framing inspection I would imagine. The house has been like this for quite some time. Luckily there was no structural damage, only the lack of a proper structure support.

Homes Today Burn Faster than Ever

It may sound like a cliche to talk about fire safety tips in the central New Jersey area
during the holiday season, but if there’s one statistic that bears
repeating, it’s this: Even with adequate smoke alarms, a house fire today can
become uncontrollable in less than(3) three minutes.

That’s down from an average 17 minutes in 1975 — a whopping 82 percent
difference. And the reason for the drastic change, according to a report by the National Institute of
Standards and Technology
, isn’t just the type of house you live in, but what you put inside.
“It’s not how old the home is, but it’s the furnishings,” Jack Watts,
Director of the Fire Safety Institute, told AOL Real Estate.

A spokesperson for the National Association of State Fire Marshals told AOL
Real Estate
that the worst culprit in home fires is upholstered
furniture, because it often contains highly flammable polyurethane foam. These
all-too-common materials provide the fuel for what fire experts call the
flashover — the point at which everything in the room simultaneously bursts
into flames. It doesn’t help that many of today’s homes are built with more
open floor plans and modern building materials like wallboard that can lead to
faster fires, according to the Wichita Eagle.

The numbers show an alarming trend. In 1977, the first year when data was
available, there were 750,000 residential fires, according to the National Fire Protection Association.

In 2010, there were roughly half that many, thanks in large part to widespread use of smoke detectors. But the incredible speed with which  home fires can spread in today’s homes represents a major step backward in fire
safety.

Don’t Let the Air Out

The use of proper caulking, weatherstriping, backer rods and spray foam to help stop air from leaking out of your livingspace. Apply these sealants around windows and doors, electrical conduits and pipes, electrical receptacles located on exterior wall and wherever conditioned air can escape to the outside.  Adding insulation especially in the attic can make a big difference in energy efficiency, utility bills and your family’s comfort. One last thing to check, the duct system in forced air systems. Check for adequate air flow/or the lack of air flow that may indicate a disconnected duct.

Cure for Bedbugs

The elimination of bedbugs has become a big problem for hotels and places that recieve guests for an indeterminate stay.  The EPA has created a website that describes how to get rid these pests for good using a safe EPA pesticide, along with removal of clutter, covering matresses, vacuuming and other steps.

Chinese Drywall

Chinese Drywall

The American Industrial Hygiene Association (AIHA) has just released the white paper on  corrosive/oe chinese drywall according to a news item submitted by Kenneth Kruger, ACI as was noted in the December 2010 issue of the ASHI Reporter.  This documentation helps to identify the many problems associated with corrosive drywall.

Chinese Drywall

Corrosive drywall (CDW) was installed in thousands of homes and buildings mostly in the southern part of the United States as early as 2001.  It has high levels of elemental sulfur, which caused problematic hydrogen sulfide emmissions.

These emmissions have a very strong rotten egg odor, cause major damage to homes by destroying copper, and cause health concerns in the form of allergy-like symptoms, as well as headaches and nose bleeds. Homes that have Chinese drywall are being gutted completely, because the repair requires replacement of the drywall in the copper in the home – plumbing pipes, electric wires, electric panels, aire conditioners…etc.

As noted in Florida, Lousiana and Virginia but not limited to these regions.  Metal components connected to electric receptacles and pipes hidden within walls were considered to have serious corrosive defects.
