Common Issues Based on the Age of the Home
Common Home Inspection Issues Based on the Age of the Home
When touring homes, buyers will find a wide variety of properties spanning different eras of construction, each with its own character, strengths, and potential maintenance considerations. While older homes often offer charm, unique architectural details, and solid craftsmanship, newer homes may provide modern features and energy efficiency. Regardless of age, every home requires upkeep, and understanding common inspection items can help buyers identify both potential concerns and signs of a well-maintained property. Below, we outline what to look for in homes from different time periods, how to recognize signs of previous repairs, and estimated costs for addressing common issues. (All costs noted below are general estimates for high level budgeting only. Please consult with a specialized professional to get specific quote any work needed.)
Homes Built Before 1950 Older homes have charm and craftsmanship, but they often come with outdated systems and potential safety concerns:
Knob-and-Tube Wiring: Many homes from this era still have outdated electrical systems that may not meet modern safety standards.
How to Identify: Look for ceramic knobs and tubes in the basement or attic. Ask for an electrical inspection.
Fix & Cost: Full rewiring can cost between $8,000–$15,000, depending on home size.
Lead-Based Paint & Pipes: Homes built before 1978 may have lead paint, and even earlier homes might have lead piping.
How to Identify: Chipping or peeling paint may contain lead. Lead pipes are dull gray and can be scratched to reveal shiny metal underneath.
Fix & Cost: Encapsulation or removal of lead paint costs $1,000–$10,000. Lead pipe replacement can cost $2,000–$5,000.
Foundation Issues: Settling and shifting over time can cause cracks and instability.
How to Identify: Check for sloping floors, large foundation cracks, or doors that don’t close properly.
Fix & Cost: Minor cracks can be sealed for $500, while major foundation repair can cost $5,000–$15,000.
Asbestos Materials: Older insulation, flooring, and siding may contain asbestos, which can be hazardous if disturbed.
How to Identify: Professional testing is required, as asbestos is not always visible.
Fix & Cost: Encapsulation is around $500–$1,500, while full removal can cost $2,000–$10,000.
Homes Built Between 1950–1970 Mid-century homes feature solid construction but often require updates:
Galvanized Plumbing: These pipes corrode over time, restricting water flow and leading to potential leaks.
How to Identify: Discolored water and low pressure are common signs.
Fix & Cost: Replacing with copper or PEX piping can cost $4,000–$10,000.
Aluminum Wiring (1960s–70s): Used as a substitute for copper, aluminum wiring can pose fire risks due to poor connections.
How to Identify: Look for aluminum wires stamped with “AL” in the electrical panel.
Fix & Cost: Adding copper connectors costs around $300–$500 per outlet, while full rewiring can cost $8,000+.
Outdated HVAC Systems: Many homes still rely on inefficient heating and cooling systems that need replacement.
How to Identify: Check the age of the system; anything over 15 years may need replacement.
Fix & Cost: A new HVAC system can cost $5,000–$12,000.
Homes Built Between 1970–1990 These homes tend to have more modern designs but can still present some concerns:
Polybutylene Plumbing (1978–1995): This type of piping is prone to leaks and may require replacement.
How to Identify: Gray plastic pipes marked “PB” in exposed areas.
Fix & Cost: Repiping costs $4,000–$15,000.
Roofing Concerns: Roofs from this era may be nearing the end of their lifespan, depending on materials used.
How to Identify: Curling or missing shingles, leaks in the attic.
Fix & Cost: Roof replacement ranges from $5,000–$15,000.
Insufficient Insulation: Many homes were built with lower insulation standards, affecting energy efficiency.
How to Identify: Cold spots in winter, high energy bills.
Fix & Cost: Adding insulation costs $1,500–$3,000.
Mold & Moisture Issues: Homes with poor ventilation may develop mold problems, especially in bathrooms and basements.
How to Identify: Musty smell, visible mold spots.
Fix & Cost: Mold remediation costs $1,500–$6,000.
Homes Built After 1990 Newer homes generally have fewer structural concerns but can still have maintenance needs:
Stucco & Moisture Problems: Poorly installed stucco can trap moisture, leading to potential damage.
How to Identify: Soft spots, discoloration, or cracks on the exterior.
Fix & Cost: Repair costs range from $3,000–$10,000.
Foundation Settling: While normal, excessive settling can indicate construction defects.
How to Identify: Cracks in drywall, uneven floors.
Fix & Cost: Structural reinforcement can cost $2,000–$10,000.
Appliance & System Longevity: Water heaters, HVAC systems, and roofing materials may start needing replacement after 15–25 years.
How to Identify: Check manufacturer labels for installation dates.
Fix & Cost: Water heaters cost $1,000–$3,500; HVAC systems cost $5,000–$12,000.
Regional Concerns: Colorado-Specific Issues
Foundation and Siding Issues Due to Settling: Colorado’s expansive soil can cause significant foundation shifting over time. This can lead to cracks in walls, uneven flooring, and damage to siding, especially in homes with poor drainage or improper grading.
How to Identify: Gaps between walls and floors, cracked siding, doors sticking.
Fix & Cost: Structural repairs cost $3,000–$15,000. Installing a proper drainage system can help prevent future issues ($1,500–$5,000).
Radon Exposure: Colorado has some of the highest radon levels in the country. This colorless, odorless gas can seep into homes through cracks in foundations and basements, posing a health risk.
How to Identify: Radon test kits or professional inspections.
Fix & Cost: Radon mitigation systems cost $800–$2,500.
Final Thoughts As you tour homes, keep in mind that while no property is without maintenance needs, a well-cared-for home can provide exceptional longevity, value, and character.
