Imagine leaving a window open all winter long -- the heat loss, cold drafts and wasted energy! If your home has a folding attic stair, fireplace or clothes dryer, that may be just what is occurring in your home every day. These often overlooked sources of heat loss and air leakage can cause heat to pour out and the cold outside air to rush in -- costing you higher heating bills. Air leaks are the largest source of heating and cooling loss in the home. Air leaks occur through the small cracks around doors, windows, pipes, etc. Most homeowners are well aware of the benefits caulk and weatherstripping provide to minimize heat loss and cold drafts. But what can you do about the four largest “holes” in your home -- the folding attic stair, the whole house fan, the fireplace and the clothes dryer? Here are some tips and techniques that can easily, quickly and inexpensively seal and insulate these holes. Attic Stairs When attic stairs are installed, a large hole (approximately 10 square feet) is created in your ceiling. The ceiling and insulation that were there have to be removed, leaving only a thin, unsealed, sheet of plywood. Your attic space is ventilated directly to the outdoors. In the winter, the attic space can be very cold, and in the summer it can be very hot. And what is separating your conditioned house from your unconditioned attic? That thin sheet of plywood. Often a gap can be observed around the perimeter of the door. Try this yourself: at night, turn on the attic light and shut the attic stairway door -- do you see any light coming through? These are gaps add up to a large opening where your heated/cooled air leaks out 24 hours a day. This is like leaving a window open all year round. An easy, low-cost solution to this problem is to add an attic stair cover. An attic stair cover provides an air seal, reducing the air leaks. Add the desired amount of insulation over the cover to restore the insulation removed from the ceiling. Whole House Fans Much like attic stairs above, when whole house fans are installed, a large hole (up to 16 square feet or larger) is created in your ceiling. The ceiling and insulation that were there have to be removed, leaving only leaky ceiling shutter between the house and the outdoors. An easy, low-cost solution to this problem is to add a whole house fan cover. Installed from the attic side, the whole house fan cover is invisible. Cover the fan to reduce heating and air-conditioning loss, remove it when use of the fan is desired. If attic access is inconvenient, a ceiling shutter cover is another option for reducing heat loss through the ceiling shutter. Made from R-8, textured, thin, white flexible insulation, and installed from the house side over the ceiling shutter with Velcro, a whole house fan shutter cover is easily installed and removed. Fireplaces Sixty-five percent, or approximately 100 million homes in North America are constructed with wood or gas burning fireplaces. Unfortunately there are negative side effects that the fireplace brings to a home especially during the winter home-heating season. Fireplaces are energy losers. Researchers have studied this to determine the amount of heat loss through an unlit fireplace, and the results are amazing. One recent research study showed that an open damper on an unlit fireplace in a well-insulated house can raise overall heating-energy consumption by 30 percent. This is truly a remarkable statistic! A recent study showed that for many consumers, their heating bills may be more than $500 higher per winter due to the air leakage and wasted energy caused by fireplaces. Why does a home with a fireplace have higher heating bills? It is simple - hot air rises. Your heated air leaks out any exit it can find, and when your heated air is drawn out of your home, cold outside air is drawn in to make up for it. The fireplace is like a giant straw sucking the heated air from your house! An easy, low-cost solution to this problem is to install a fireplace draftstopper. Available from Battic Door, a company known for their energy conservation products, a fireplace draftstopper is an inflatable pillow that is installed into the fireplace below the damper. As the pillow is inflated, it seals the damper, eliminating any air leaks and heat loss. Other benefits include the reduction of downdrafts, toxins, odors, pollutants, and noise. The pillow is removed whenever the fireplace is used, then reinserted after. Completely reusable and available in two sizes to fit any masonry or zero-clearance fireplace, the draftstopper can pay for itself in less than a month! Clothes Dryer Exhaust Ducts In many homes, the room with the clothes dryer is the coldest room in the house. Your clothes dryer is connected to an exhaust duct that is open to the outdoors. In the winter, cold air leaks in through the duct, through your dryer and into your house. Dryer vents use a sheet-metal flapper to try to reduce this air leakage. This is very primitive technology that does not provide a positive seal to stop the air leakage. Compounding the problem is that over time, lint clogs the flapper valve causing it to stay open, or a cold breeze can blow the flapper open, allowing frigid air right to come right into the house. An easy, low-cost solution to this problem is to add a dryer vent seal. This low-cost, easily installed vent is mounted on the outside of your house, and reduces unwanted air infiltration, and keeps out pests, bees and rodents as well. The vent will remain closed unless the dryer is in use. When the dryer is in use, a floating shuttle rises to allow warm air, lint and moisture to escape. If your home has a folding attic stair, a whole house fan, a fireplace, and/or a clothes dryer, you can easily, quickly and inexpensively seal and insulate these holes.

Last month we started Part 4 of an 8 part series of Preventive Maintenance Tips for your Home. This month we will discus helpful tips for maintenance every 2 years. Every 2 Years

AIR DUCTS:
Consider having the air ducts in your home cleaned if family members suffer excessively from respiratory infections, asthma or allergies; if there is visible mold growth inside ducts or on other components of your heating and cooling system, the ducts are infested with insects or rodents. Excessive amounts of dust and debris and/or particles are actually released into the home from your supply registers.

CARBON MONOXIDE DETECTOR:
Change sensor element.

DECKS AND PORCHES:
If they are professionally cleaned, sealed and maintained, it should only be necessary to refinish and/or stain your wooden decks every two or three years. It is necessary that surfaces be thoroughly cleaned and dried before adding another coat of stain or protective finish. Remove mold and mildew, fungus, tree sap, grease and bird droppings from exterior wood with the appropriate commercial deck cleaner (or homemade mixture) and a stiff brushed broom. Clean mildew and fungus by mixing one cup of chlorine bleach per gallon of water; scrub and rinse well. Sodium bicarbonate works well to remove dirt, mildew and the weathered gray residue from sunlight degradation. Oxalic acid will remove metal stains around nails and dark tannin stains often found on redwood, cedar and oak. Use care and follow manufacturers’ directions when using these products, wear eye protection, long pants, long sleeves and gloves; cover surrounding vegetation with plastic and rinse well.

TILE, NATURAL STONE AND GROUT:
Have your grout, professionally sealed every one to three years in medium to heavy-used areas and every three to five years in lightly used areas.

SEPTIC TANK:
Have the septic tank cleaned and pumped. Join me next month for Part 6 of our series on Preventive Maintenance Tips for your Home. We will be starting with tips for each season st Spring Visit us at www.freminshomeimprovement.com

Q. We are looking at new homes in South Carolina, and we noticed that some are built on a slab, and others have crawl spaces. Is one better than the other?

A. Traditionally, houses in South Carolina have been built on raised foundation walls to keep the structure away from the ground, but with the advent of newer technologies, more and more builders are choosing to build homes with concrete slab foundations. Briefly, a house with a crawl space has a wooden floor built on foundation walls and piers that can be anywhere from about two to six feet off the ground depending on the slope of the lot. In this type of house, the utilities such as plumbing, electrical and HVAC can be run under the floor, and are accessible for repair or renovation. The crawl space has fresh air ventilation, but is closed to insects and animals. This type of construction requires stairs for access. A slab-built house, or patio home, is built directly on a reinforced concrete slab foundation. This slab rests directly on the ground, and the utilities are run under the slab and brought up into the structure wherever needed. The heating and air ducts are routed through the attic in most cases. This type of construction requires no stairs for access. With a house built up off the ground, modest amounts of water entering the crawl space during rainstorms is not usually a problem, because it runs right through or evaporates through the fresh air vents. With a slab house, there is very little tolerance for water draining against the structure, because it will find its way into the house. If you are considering buying a patio home, pay careful attention to the lot drainage. The choice between the two types of construction is largely a matter of personal preference unless someone in your family has difficulty climbing stairs in which case, a slab-built home would be your best choice. Regardless of which type of house you choose to purchase, it would be wise to get a thorough home inspection from the most competent inspector in the area.

Q. Our home inspector said that parts of our sidewalk are a potential trip hazard. We think that he is being too picky and splitting hairs. What do think about cracks in sidewalks?

A. Simple cracks in a concrete sidewalk are not necessarily a problem unless they become large enough to catch the heel or toe of a shoe or the tip of a cane. Cracks normally indicate movement in the sidewalk, and are fairly normal. Most sidewalks that are more than 20 years old will have some cracks. On the other hand, upheavals in sections of the sidewalk can be a liability. Concrete sidewalks typically will have expansion joints at regular intervals. These individual sections of concrete can rise or fall as much as three inches in some extreme cases. The most common reason for upheaval is tree roots. The opposite problem is caused by subsidence where the ground beneath the slab sinks. An upheaval of more than one inch can become a dangerous trip hazard, and a liability to you as the home owner. This type of trip hazard is particularly dangerous at night. In my practice, I always explain this to the client, and encourage them to make repairs.

Galvanized pipes have a general life expectancy of 50 years, but this can be shortened considerably by the amount of minerals in the water supply. Columbia has naturally soft water, and galvanized pipes here tend to last longer. Other areas of the country such as Southern California have rather hard water, and as a consequence, galvanized pipes won’t last as long there. Two things happen to galvanized pipes as they age.

First, minerals tend to slowly build up on the inner walls of the pipe decreasing the inside diameter. In extreme cases, this can slow the water flow to a trickle.

The other common problem with galvanized pipes is corrosion at the joints. In the process of cutting the threads for the pipe fittings, the protective galvanizing is cut away exposing bare metal. Over time, these threaded joints will corrode and eventually break. In the case of your 80 year old house, if the pipes are original I would definitely consider replacing them. If you are not sure how old they are, I recommend that a qualified home inspector examine them and look for signs of corrosion at the fittings, and check for low water flow at all of the faucets.

In the course of inspecting a home, I often find open electrical splices in the crawl space and attic, and I cite them in my report. A splice, in layman’s terms, is a connection between two or more wires. These splices are normally made with a small plastic device resembling a thimble that is called a wire nut. The wire nut is twisted onto the wires, and holds them tightly together for a good connection. In accordance with accepted electrical practice, all splices must be inside an approved electrical box with a cover, and this box must be attached to the framing of the house and accessible. These boxes are either metal or plastic. The reason why splices must be inside a covered box is very simple. When electric wires become loose or overloaded, they can get very hot, and, in some cases, throw off sparks. If the wires are out in the open, they can drop sparks onto combustible materials or otherwise cause them to ignite. The electrical box is designed to contain the heat and sparks long enough for a fuse to blow or a breaker to trip. Crawl spaces are not very nice places to work, and the person doing the wiring is probably in a hurry to get out of there, and not interested in going back to place a cover on each box. Open splices are an invitation to disaster, and should be corrected as soon as discovered. If you suspect that your home has open splices in the crawl space or attic, have a qualified electrician correct the problem as soon as possible.
