Foundation Fireplaces and Framing

Examine the foundation fireplaces for cracks exceeding 1/4 inch in width using a level tool such as the Empire e55.10 (available for under $20), with particular attention to horizontal fissures that indicate settling-a condition identified in 25% of homes according to a 2022 ASHI report.

To perform a comprehensive assessment, adhere to the following procedural steps:

1. Conduct a visual examination of concrete or masonry walls to differentiate between hairline (non-structural) and structural cracks, utilizing a flashlight in crawl spaces or basements (estimated duration: 15-20 minutes; reference InterNACHI’s foundation inspection checklist for illustrative photographs).
2. Lightly tap surfaces with a rubber mallet to identify hollow sounds suggestive of framing deficiencies; designate affected areas with painter’s tape for subsequent remediation.
3. Verify the operational integrity of the basement sump pump by engaging its activation mechanism, confirming unobstructed discharge and the absence of backups to avert potential flooding.
4. Quantify settling using a laser level, such as the Bosch GLM20 ($40), by taking measurements across the corners.

Exercise caution to avoid prevalent errors, such as disregarding moisture stains, which may precipitate mold development. For any cracks wider than 1/8 inch, engagement of a qualified professional is recommended.

Siding and Drainage

Assess the exterior siding for any gaps greater than 1/8 inch and ensure drainage grading slopes are at least 5% away from the foundation to prevent water intrusion, which impacts 40% of properties based on HomeAdvisor’s 2023 data.

To perform a comprehensive inspection, adhere to the following procedures:

1. Examine siding materials, such as vinyl, by utilizing a moisture meter, for example, the General Tools MMD4E (priced at $25), to identify rot; dedicate 10-15 minutes to each side.
2. Evaluate the grading using a 10-foot level, confirming that downspouts divert water 5-10 feet from the structure in accordance with EPA stormwater management guidelines.
3. Inspect retaining walls for signs of bulging by verifying their vertical alignment with a plumb bob.
4. Review driveways, patios, garages carports for cracks exceeding 1/2 inch in width.

Steer clear of frequent oversights, such as overlooking the risks of ice dams on balconies decks. Should regrading be required, allocate a budget of $1,000 to $3,000 for remedial measures that promote effective drainage and safeguard the structural integrity of the property.

Roof and Attic Inspection

Roof and attic inspections identify structural and maintenance issues in 35% of homes, including examples such as missing shingles that may require replacement costs ranging from $4,000 to $10,000. These findings are derived from a 2021 survey conducted by the National Association of Realtors, which analyzed data from 5,000 inspections.

Shingles and Flashing

Conduct a thorough examination of the asphalt shingles for curling edges or bald spots that cover more than 10% of the surface area. Utilize binoculars, such as the Nikon Action 10×50 model (approximately $100), from ground level to assess the integrity of the flashing seals around roof chimneys.

1. Subsequently, inspect the downspouts gutters for granule loss, where normal accumulation should not exceed 1 cup per 100 square feet. Use a trowel to scoop and measure the granules accurately.
2. Probe the chimney flashing with a screwdriver to identify any rust or gaps; allocate 20-30 minutes for this task. Per the guidelines of the Asphalt Roofing Manufacturers Association (ARMA), replace the flashing if cracks exceed 1/8 inch.
3. Examine the valleys for debris accumulation and clear it using a leaf blower, such as the Toro 51621 model ($80), to prevent water pooling.
4. Verify the downspout connections for leaks by performing a hose test.
5. Inspect soffit vents and attic roof for proper insulation ventilation and blockages.

Adhering to these steps, which conform to ARMA best practices, facilitates the early detection of 80% of potential issues, thereby mitigating the need for costly repairs.

Interior Evaluation

According to InterNACHI’s 2023 findings, interior evaluations reveal hidden defects in 50% of inspections, such as uneven floors that signal structural settling. The average cost to repair these issues amounts to $1,500 per room.

Walls, Floors, and Ceilings

To assess walls, wall coverings for moisture, utilize a pinless moisture meter, such as the Klein Tools ET140 (priced at $30), to ensure levels remain below 15%. Additionally, examine the surfaces for bulges or stains, which may indicate plumbing leaks-a common issue affecting approximately 20% of older homes.

1. Proceed to evaluate floor evenness by rolling a marble across the surface; any slope exceeding 1 inch over 10 feet suggests potential foundation problems. This inspection can be completed for each room in approximately 15 minutes.
2. Gently tap the ceilings to detect hollow sounds, which may signify water damage, and subsequently use a long pole to probe any soft areas.
3. Inspect the seams of drywall for cracks resulting from settling; it is crucial to differentiate between superficial cosmetic cracks and those that may conceal underlying issues, such as electrical wiring problems.

Do not overlook minor cracks, as they frequently conceal more significant structural concerns. Addressing these issues early can save up to $3,000 compared to remediation after relocation, in accordance with the U.S. Department of Housing and Urban Development (HUD) housing inspection guidelines.

These procedures facilitate a comprehensive, do-it-yourself home evaluation that can be performed in less than one hour.

Windows and Doors

Examine the seals of windows insulation for any fogging between the panes, which serves as an indicator of failure in approximately 30% of double-glazed units according to Energy Star ratings. Additionally, test the operation of exterior doors to ensure smooth latching without any binding.

Proceed with a systematic evaluation to identify potential issues.

1. Operate each window and door 5 to 10 times, inspecting for sticking or gaps in the weatherstripping that exceed 1/16 inch, as such gaps may permit drafts to enter.
