As a Registered Home Inspector serving the Aurora community for over a decade, I've walked through countless homes across our beautiful town, from the historic properties near Machell Avenue to the newer developments in the northwest end. While every home inspection tells its own story, certain issues appear with remarkable consistency. Today I want to share the five most common findings that emerge during home inspections in Aurora, along with the real costs homeowners face when addressing these concerns.

Aluminum wiring tops my list of frequent discoveries, particularly in homes built between 1965 and 1975. Aurora experienced significant growth during this period, and many of these charming properties still contain the original aluminum branch circuits. The challenge with aluminum wiring isn't immediate danger when properly maintained, but rather the long-term concerns about loose connections and potential fire hazards. I regularly find overheated outlets, flickering lights, and that telltale burning smell that makes homeowners nervous.

The replacement costs for aluminum wiring vary dramatically based on home size and accessibility. A typical Aurora home might require anywhere from $8,000 to $15,000 for complete rewiring, though smaller homes or partial updates could run between $3,000 and $6,000. Some homeowners opt for aluminum-rated devices and proper connectors as a temporary solution, which typically costs $1,500 to $3,000, though this approach requires ongoing vigilance.

Poly-B plumbing represents another significant concern I encounter regularly. Installed extensively throughout the 1980s and early 1990s, this gray plastic piping seemed revolutionary at the time. Unfortunately, these systems are now reaching the end of their expected lifespan, and I frequently document brittle connections, pinhole leaks, and failing fittings. The material becomes increasingly unreliable after 25 to 30 years, making it a priority concern for Aurora homeowners.

Replacing Poly-B plumbing typically ranges from $8,000 to $18,000 for a complete home repipe, depending on the size of the house and accessibility of the plumbing runs. Partial replacements or repairs to the most critical areas might cost between $2,500 and $5,500, though this approach often leads to ongoing issues as other sections fail progressively over time.

Foundation concerns appear in various forms throughout Aurora homes. Our clay soil conditions, combined with freeze-thaw cycles, create unique challenges for foundations. I regularly document hairline cracks in poured concrete foundations, stepped cracks in block foundations, and occasional settling issues. Most cracks I encounter are minor and relate to normal settling, but some indicate more serious structural concerns or water infiltration problems.

Foundation crack repairs vary enormously based on severity and location. Simple cosmetic cracks might cost $300 to $800 to seal properly, while structural repairs can range from $1,500 to $5,000. More extensive foundation issues, including underpinning or major structural work, can reach $15,000 to $30,000 or more, making early intervention crucial.

Roofing wear consistently appears in my inspection reports, particularly on homes with asphalt shingles approaching the 20-year mark. Aurora's weather patterns, including ice damming in winter and intense summer heat, take their toll on roofing materials. I frequently find missing or damaged shingles, inadequate ventilation, and aging flashing around chimneys and roof penetrations.

Roof replacement costs in Aurora typically range from $12,000 to $25,000 for asphalt shingles, depending on the home size and roof complexity. Partial repairs or maintenance work might run $1,500 to $4,500, though extensive repair costs often approach replacement pricing, making full replacement the more sensible long-term investment.

HVAC failures round out my top five findings. Many Aurora homes still rely on aging furnaces and air conditioning systems that struggle with efficiency and reliability. I regularly encounter furnaces over 20 years old, ductwork problems, and inadequate ventilation systems that impact both comfort and indoor air quality.

Just last month, I inspected a lovely home on Industrial Parkway where the homeowners had been dealing with uneven heating for years. The original 1980s furnace was oversized for the space, the ductwork had never been properly sealed, and the aging system was consuming energy at an alarming rate. The complete HVAC upgrade, including a new high-efficiency furnace, ductwork modifications, and improved ventilation, cost approximately $12,000 but transformed their home comfort and reduced their monthly energy bills significantly.

HVAC replacements typically range from $6,000 to $15,000 for complete systems, while repairs and maintenance might cost $500 to $2,500 depending on the specific issues identified.

Understanding these common concerns helps Aurora homeowners make informed decisions about their properties. Remember, a thorough home inspection isn't meant to discourage you from purchasing a home, but rather to provide the knowledge needed for confident homeownership decisions.
