New article on sewer gases in the home

September 24th, 2010

Gases from the sewer are extremely toxic, foul and even explosive. One of its constituent gases is so dangerous that it’s actually used as a chemical weapon while another is so heavy that it will quickly displace oxygen and suffocate anyone nearby. In most cases, these gases remain in the sewer, but they can enter the living space through dried out plumbing fixtures, plumbing cracks and other sources. To find out more about the danger, how it arises and what to do about it, please read out new article on sewer gases in the home.

New article on eyebrow dormers

New article on kerosene heater inspection

September 21st, 2010

Kerosene is a cheap fuel and it burns efficiently, which is why kerosene heaters are popular as space heaters in the US and even a source of primary home heat in Japan. But they smell bad and they pose serious fire hazards if they aren’t constructed, maintained or operated properly. They should have a low center of gravity, for instance, so they are unlikely to top over. To find out more, read our new article on kerosene heater inspection.

New article on ventless fireplace inspection

September 21st, 2010

Ventless fireplaces are enjoyed for their energy efficiency and ease of installation, but they’re thought by many to be a horrifically dumb idea; they vent their products of combustion, including toxic carbon monoxide, directly into the living space. Some of the critics of this fireplace design are entire countries and states that have banned them, not to mention the CDC, the EPA and various other watchdog groups that strongly oppose their use. There are ways you can prevent deadly carbon monoxide leaks, and you can find out about them and more in our new article on ventless fireplace inspection.

New article on condensation inspection

September 16th, 2010

Cold surfaces cool their surrounding air, forcing water vapor closer together until it condenses. It’s common on water pipes because metal – especially copper – has high thermal conductivity, which means it’s likely to cool quickly in response to a brief exposure to cold water or air. There are ways to prevent condensation in homes, which can cause mold growth and a variety of other building ailments. To find out more, read our new article on condensation inspection.

New article on water stoves

September 15th, 2010

Water stoves are used to heat homes and domestic water, and they’re conveniently located outside of the house. While this frees up room in the house and improves indoor air quality, water stoves are notoriously inefficient and release large amount of smoke into the air. Due to their status as a public health threat, many jurisdictions have outlawed or restricted their use. To find out about installation requirements and more, check out our new article on water stoves.

New article on electric fence inspection

September 10th, 2010

Electric fences are typically used on residences and farms to keep pets and livestock safe from traffic or the mouths of hungry coyotes. But more can go wrong with these systems than you might expect – dry soil impedes grounding and weakens the fence, an errant spark leaves the fence and starts a fire, or the owner designed it to be far too powerful. Lightning, too, is a major concern with these systems. To find out more about their design and hazards, read our new article on electric fence inspection.

New article on mudjacking

September 8th, 2010

Mudjacking might not sound attractive, but it’s a clean, cheap and environmentally friendly way to fix uneven concrete. A slurry of sand, clay, polymers and other materials are pumped beneath the sunken concrete, which is forced to rise back into place before the slurry hardens. The alternative, which involves tearing out and replacing the old concrete, is usually a lot more expensive and cumbersome. To find our more about the process, its advantages and limitations, check out our new article on mudjacking.

New article on snow guard inspection

September 8th, 2010

A cubic foot of ice weighs more than 50 pounds, which can be pretty dangerous if it slides off a roof.

To read about their installation requirements, why they’re needed and how they can actually be counterproductive, take a look at our new article on snow guard inspection.

New article on Poison ivy, oak and sumac

September 7th, 2010

Most people are allergic to the oil found in poison ivy – urushiol – but few people realize just how toxic it can be. 500 people can develop a rash from the amount of urushiol oil required to cover the head of a pin, and inhaled vapors of the oil can cause serious injury or death. And it’s virtually everywhere in the United States in Canada, mostly in the leaves, vines and roots of poison ivy, oak and sumac. To learn how to identify these plants, where they’re found and what you can do to protect yourself and your clients, take a look at our new article on poison ivy, oak and sumac.

New article on fireplace fuel

September 7th, 2010

Fireplaces and wood stoves are designed to burn dried, cut firewood, but many homeowners throw in various other items, some of which may release toxic fumes or damage the fireplace’s components. Pressure-treated wood, for instance, may release toxic amounts of arsenic, and driftwood contains enough salt to damage catalytic converters in wood stoves. Pallets, however, may be safe to burn as long as they were not treated with insecticides. To find out more, check out our new article on fireplace fuel.
