Many homes, buildings, condo units, and co-op units have had changes made to the interior.The interior of the home is examined as part of a Professional Engineer's home inspection. While inside the home, building, condo, or co-op, the Professional Engineer evaluates the structural system, the heating system, the air-conditioning system, the electrical system, the plumbing system, the windows, the appliances, etc. Ways you can help protect the environment are reported. Concerns such as evidence of water in the basement, roof leakage, and wood-destroying insect evidence are examined. The engineering reports include an expense analysis where appropriate.

Many homes, buildings, condos, and co-ops have had changes made to the interior. A change could be as simple as a dishwasher installation or as complex as major renovations. The change may not have been done correctly. Our Professional Engineers looks for indications of problems that exist in the interior of the structure. You are also advised of potential Certificate of Occupancy issues.

The home, building, condo, or co-op inspection includes examining the fireplace. Unfortunately, using a fireplace in a new or renovated home or building can be hazardous.

Fireplace Hazards

Windows and Doors

The windows and doors are important functional components of a house or building. Most windows and doors are functional in that they can be opened and closed, although sometimes this requires considerable effort.

In some home inspections, building, condo, and co-op, especially older buildings, poor operation of windows and doors is due to normal settlement or normal wear and tear. Sometimes, improper window or doors operation is due to structural defects in the building.

The Professional Engineer analyzes the window and door operation to determine if there are structural defects. For any problems found, the expense analysis in the inspection report helps you plan for future expenses.


Window replacement is an expense many buyers choose to undertake.Window replacement is an expense many buyers choose to undertake. The Professional Engineer's evaluation of windows determines whether they function properly. This includes checking for evidence of excessive wind or water leakage, damage, etc. Even if the Professional Engineer finds that the windows function, you may choose to replace them for personal reasons.

Windows are also checked for other concerns such as the need for caulking, draftiness, ease of operation, and leakage. Many older windows are drafty, leak when it rains, and are difficult to operate. Even newer windows may have problems.

Old windows are not as energy efficient as modern windows. Buildings constructed during the 1960s may have leaky aluminum windows, while older houses have leaky double-hung wooded windows. Buildings constructed before World War II may have leaky metal casement windows.

Even with storm windows in place, the old windows are not as energy-efficient as modern windows. Today, windows are typically double-glazed to help reduce heating and cooling costs. New windows are better insulated and require less maintenance than older windows.


Just like with the operation of the windows, door operation can be a clue to structural problems in a building.Just like with the operation of the windows, door operation can be a clue to structural problems in a building. A door that binds may just be swollen due to moisture, or the binding  may indicate an underlying structural defect. A doorframe that is not level may be the result of normal settlement or may indicate a structural defect. A gap around a door may be present due to an underlying structural defects.

Older doors are not as energy efficient as modern doors. Even with storm doors in place, the old doors are not as energy-efficient as modern doors. Often, old doors have significant air leakage.

Today, doors typically contain insulation to help reduce heating and cooling costs. Doors also require less maintenance than older doors.

Home Appliances

Heimer Engineering's Professional Engineers check appliances for general condition, correct installation, and functionOur Professional Engineers check appliances for general condition, correct installation, and function. You are also advised of possible problems repairing old appliances.

Most homes, condo, and co-op have a wide variety of appliances including a range, refrigerator, microwave oven, conventional oven, dishwasher, clothes washer, clothes dryer, and other appliances. Since it is not possible to run every appliance through every cycle during a pre-purchase inspection, our Professional Engineers are trained to look for indicators of problems. You are provided with an expense analysis of needed repairs in the inspection report.

Most homeowners depend on their appliances every day, so most appliances are at least partially functional.Homeowners depend on their appliances every day, so most appliances are at least partially functional. The appliance hookup may be incorrect or even hazardous.

The Professional Engineers often find houses that have had an electric self-cleaning oven, an electric dryer, or a room air-conditioner installed after the house was constructed. The original electrical service may have been sufficient when the house was built. The added loads have created a hazardous condition. An incorrect appliance gas hookup can be extremely hazardous.

Fireplace and Wood
Stove Hazards

Fireplaces, wood-burning stoves, and coal-burning stoves can create hazards in a home:Many people like fireplaces, and look for a house that has a working wood-burning fireplace. Fireplaces, wood-burning stoves, and coal-burning stoves can create hazards in a home:

  • Fireplaces and stoves often have hot surfaces exposed. This means an increased risk of fire, and an increased risk of burns. Small children, elderly people, and pets are especially at risk for injury.
  • Energy-efficient windows and other steps to make homes use less energy result in less ventilation. This can result in toxic gas buildup, which can cause serious injury or death.
  • Wood and coal may give off carcinogenic substances when they burn.
  • Soot give off by burning wood and coal can dirty the interior of the home, condo unit, or co-op unit.Carbon-monoxide gasses, which can cause injury or death, may build up inside the home from burning wood or coal.

Carbon Monoxide

In addition, there are other issues created by the use of a fireplace in a home:

  • Soot give off by burning wood and coal can dirty the interior of your home.
  • Dust is often carried in with the wood and coal, which dirties the interior.
  • Fireplaces, wood-burning stoves, and coal-burning stoves can pollute the atmosphere.
  • For all of these reasons, it is recommended that you not burn wood or coal in your home.Fireplaces, wood-burning stoves, and coal-burning stoves may increase energy usage. This is because cold air from the outside is drawn in when the wood or coal burns.
  • Wood and coal often come in heavy packages. There have been reports of back injuries from carrying wood and coal into a home.

For these reasons, it is recommended that you not burn wood or coal in your home. Note that gas-burning fireplaces have some, but not all, of these issues. If you would like a fireplace, consider a propane or natural gas-burning fireplace.
