What is a home inspection?

A general home inspection is a visual inspection conducted by a highly trained and certified professional for the purpose of identifying past, present, and potential or foreseeable issues or areas of concern.

While working for you, A-Pro 5 Rivers TN Home Inspection reports on:

• Structural Systems Inspection
• Roofing Systems Inspection
• Exterior Systems Inspection
• Interior Systems Inspection
• Electrical Systems Inspection
• Heating & Cooling Systems Inspection
• Insulation Systems Inspection

Structural Systems Inspection

A home’s structural integrity is critical. If not structurally sound, a home poses the threat of serious safety issues and significant costs down the road. Almost every component of a home provides clues as to what is going on with its structure. Our structural analysis provides clients with a written opinion of the structural system’s performance from top to bottom, including inspection of:

• Foundations
• Drainage and Grading around Foundation
• Structure of Roof
• Material of Roof Covering
• Attic

Let’s discuss each of the components listed above:

Foundations

Concerns about the foundation are typically at the top of the list relating to a home’s structure.  Foundation repairs are expensive, and foundation problems often cause other costly home repairs. Your A-Pro 5 Rivers TN Home Inspection understand your concerns. Our inspections include a comprehensive analysis of the home’s foundation as part of the structural systems analysis. Your inspector reports on the visible condition of these foundation-related areas:

• High and Low Points of the Foundation (evaluated through a Foundation Level Survey)
• Foundation Cracks
• Visible Foundation Deflections
• Sloping Floors
• Floor Movement
• Cracks within Interior and Exterior Wall Systems
• Doors and Windows negatively impacted by home movement
• Framing Components and Trim negatively impacted by home movement

Roofing System Inspection

The roof structure is a key component of the structural systems analysis. It must be engineered to properly distribute the live and dead loads to the foundation. Your A-Pro 5 Rivers TN Home Inspection inspector examines the roofing structure from both the exterior and interior to evaluate its condition and note the following condition issues:

• Sagging Ceilings
• Wood Rot
• Wet Insulation
• Ridge Separation
• Loose Knee Braces
• Loose Rafters
• Moisture Intrusion
• Insect or Rodent Presence
• Fire Damage

Roof Covering Materials

The roof covering’s primary purpose is to shield the home’s interior from the effects of adverse weather. Your A-Pro 5 Rivers TN Home Inspection inspector examines the roof and reports the roof material type as well as any visible conditions that prohibit the roofing material from performing its job. Your inspector may or may not climb on the roof to inspect it. Drones, telephoto lenses and other improving technologies are being used more frequently when a roof poses safety hazards or may be damaged if walked upon.

Attic

An attic inspection can disclose significant problems.

Although the attic may not be on the buyer’s mind, there are many reasons why it’s one of the most important areas of concern for home inspectors. An attic inspection should not be overlooked because it can tell much about the history of a home. It can provide evidence of potentially significant problems that may not be disclosed by the home seller or even acknowledged by the current occupant of the home.

While in the attic, your A-Pro 5 Rivers TN Home Inspection inspector evaluates the structural components of your roofing and framing systems, the chimney, and insulation and ventilation systems. Your inspector will also check for evidence of wood rot, moisture intrusion, fire damage, and the presence of insects or rodents. Accessible attic plumbing, electrical and mechanical components are also evaluated for performance and included in the report.

Exterior Systems Inspection

A-Pro 5 Rivers TN Home Inspection ’s exterior systems inspection is a visual examination of the home’s exterior walls. Your inspector evaluates performance issues such as structural support member movement and common installation problems. Because moisture intrusion is impossible to determine if there are no active or visual signs, your A-Pro 5 Rivers TN Home Inspection inspector checks common problem areas for evidence of moisture damage and deficiencies in the flashing. Long before closing, an exterior inspection can let a homebuyer know of potential problems: rotten and damaged siding; water pooling around the home; broken, rusted or damaged gutters; and peeling paint, particularly important (because of lead concerns) in homes built before 1978.

When examining interior walls, your inspector will be primarily focused on structural movement and installation deficiencies.

Windows

Your A-Pro 5 Rivers TN Home Inspection  inspector visually inspects and reports on the home’s windows. Your report will contain the type of and material used for the windows, as well the performance of a representative number of the home’s windows as they relate to operability and hardware. A home’s windows are a key component of the overall building system. Once they are completely installed it is impossible to determine framing practices and proper flashing.

Heating and Cooling Systems Inspection

Air quality and comfort are very important to a home. A properly functioning HVAC system is vital to managing moisture conditions leading to air quality and comfort. Our heating and cooling analysis provides our clients with a written opinion of heating and cooling performance at the time of inspection.

HVAC Equipment

Your A-Pro 5 Rivers TN Home Inspection inspector understands the importance of a proper functioning HVAC system. Hot, humid air creates moisture conditions within the home that are conducive to:

• Poor air quality
• Physical discomfort
• Fungi growth potential

A proper functioning system will extract humidity while conditioning your home’s air as efficiently as possible. Your A-Pro 5 Rivers TN Home Inspection inspector examines the unit for its ability to sufficiently heat and cool the home. Primary and secondary pipes and drain pans are also inspected.

Ventilation Systems Inspection

Duct System, Chases and Vents

Your A-Pro 5 Rivers TN Home Inspection inspector understands that efficient operation of a home is important. The U.S. Department of Energy estimates that the typical duct system loses 25-40% of the energy used for heating and cooling. Installations where ducts are routed through hot attics, as is often the case in residential homes, lose significantly more energy. Poorly installed and sealed ductwork can be one of the biggest causes of home energy loss.

Your A-Pro 5 Rivers TN Home Inspection inspector inspects and reports on the ventilation system. Good ventilation yields a healthier living environment, as it reduces the accumulation of offensive and/or toxic fumes. Inadequately sealed ducts and return registers can allow unconditioned air to enter the system and conditioned air to leak out, significantly affecting comfort and heating/cooling costs.

Plumbing System Home Inspection

A properly functioning plumbing system will provide clean, potable water to the home while effectively and safely removing waste, both critical to the safety and functionality of a home. Our plumbing system analysis provides our clients with a written opinion of plumbing system performance at the time of inspection, including:

• Plumbing Supply
• Distribution System
• Fixtures
• Drains, Waste and Vents
• Water Heating Equipment

Plumbing Supply

Your A-Pro 5 Rivers TN Home Inspection inspector examines and reports on the visual findings relating to the plumbing supply, including:

• Main Water Cutoff Location
