What Sellers Should Fix Before Listing

The Essential Repairs and Fixes That Prevent Deal Killing Issues During Home Inspection

Introduction

You’ve decided to sell your home. You’re ready to move forward. But before you list, you need to ask yourself an important question: What problems will a home inspector find that could kill the deal?

Home inspectors are thorough. They climb into crawl spaces. They test every system. They look for water damage, structural issues, electrical problems, plumbing failures, roof problems, and foundation concerns. If any of these issues exist and you haven’t addressed them, they’ll be discovered during the inspection. The buyer will request credits or repairs. You’ll lose leverage in negotiations. The sale could fall through.

The strategic approach: Address known problems before listing. Control the narrative. Demonstrate that you’ve taken care of the home. Prevent surprises that could derail your sale.

Let’s identify the essential fixes every seller should complete before listing.

The Critical Inspection Categories

Home inspectors evaluate multiple major systems and structural elements. Here’s what they’re looking for and what you should fix before listing:

The Roof: One of the Most Critical Issues

Inspectors spend time on roofs. They look for missing shingles, curling shingles, cracked shingles, granule loss, sagging, improper flashing, and signs of leakage. A compromised roof is one of the most expensive problems a buyer can face. If your roof is failing, they will identify it.

What to fix: If your roof is 20 plus years old or showing signs of wear (visible curling, missing shingles, water stains in attic), get a professional roofing inspection. If the inspector says you have less than 5 years of life remaining, budget for replacement before listing. You don’t want the buyer’s inspector to flag a deteriorating roof.

Cost to fix: $8,000 to $25,000 for roof replacement (varies by size and materials)

Cost of not fixing: Buyer requests $12,000 to $18,000 credit or walks away

Foundation and Basement Issues

Inspectors look for foundation cracks, water intrusion, mold, settling, and structural issues. They crawl under the house to inspect the foundation. They check basements for moisture, water stains, and evidence of past leakage.

What to fix: Minor cracks in foundation (less than one quarter inch wide and not spreading) are normal and usually don’t need attention. Larger cracks, horizontal cracks, or evidence of water intrusion require professional evaluation. If you have a wet basement or recurring moisture, address it before listing. Mold or mildew needs professional remediation.

Cost to fix: $500 for sealing small cracks, $2,000 to $5,000 for basement waterproofing, $3,000 to $10,000 for major foundation work

Cost of not fixing: Foundation issues are deal killers. Buyers will demand extensive credits or walk away.

Plumbing Issues

Inspectors test water pressure, check for leaks under sinks, test drains, look for water damage from plumbing failures, and evaluate the age and condition of water lines. If your home has old galvanized pipes, polybutylene pipes, or corroded copper, inspectors will note it.

What to fix: Fix active leaks immediately. A dripping faucet or leaking under sink cabinet suggests poor maintenance. Replace any visibly corroded or damaged pipes. If you know you have old galvanized pipes (common in homes built before 1980), plan for eventual replacement but fixing before sale isn’t always necessary if they’re currently functioning. However, polybutylene pipes should be replaced before listing as they’re known to fail.

Cost to fix: $100 to $500 for fixing leaks, $100 to $300 for replacing corroded sections, $3,000 to $10,000 for replacing polybutylene pipes

Cost of not fixing: Active leaks suggest neglect. Buyers will request credits for repair or replacement.

Electrical Systems

Inspectors evaluate the electrical panel, test outlets, check for proper grounding, look for outdated wiring, and assess the overall capacity of the system. An outdated two prong outlet in a kitchen is a red flag. Aluminum wiring is a concern. Missing breakers or reverse polarity problems are serious issues.

What to fix: Update two prong outlets in kitchens and bathrooms to three prong grounded outlets (building code requires it). Fix any outlets that don’t work. Replace any visible damaged wiring. If you know you have aluminum wiring, disclose it fully (you don’t necessarily have to replace it, but buyers will know about it). Ensure your panel has adequate capacity for modern usage.

Cost to fix: $200 to $500 for updating outlets, $500 to $2,000 for rewiring sections, $1,500 to $4,000 for panel upgrades

Cost of not fixing: Electrical issues are safety concerns. Buyers will demand fixes.

Heating and Cooling Systems

Inspectors test furnaces and air conditioning systems. They look for age, condition, and operational status. An HVAC system that’s 15 plus years old is getting near end of life. A system that doesn’t heat or cool properly raises concerns.

What to fix: Service your heating and cooling systems before listing. Make sure they’re operating at peak efficiency. If you have an old system (20 plus years), budget for eventual replacement but it doesn’t necessarily need to be replaced before sale if it’s functioning. However, if the system isn’t working, fix or replace it. A non functioning HVAC is a deal killer.

Cost to fix: $200 to $400 for professional service, $5,000 to $12,000 for furnace replacement, $4,000 to $10,000 for air conditioning replacement

Cost of not fixing: A non functioning system will be discovered. Buyers will request credits for replacement.

Water Heater

Inspectors check the age, condition, and operational status of water heaters. They look for signs of leakage or corrosion. A water heater that’s 15 plus years old is near end of life.

What to fix: If your water heater is 12 plus years old and showing signs of corrosion or leakage, budget for replacement. If it’s working fine but old, you don’t need to replace it before sale, but disclose the age. Buyers expect to replace water heaters eventually anyway.

Cost to fix: $1,200 to $2,500 for water heater replacement

Cost of not fixing: Minor issue compared to other systems. Not usually a deal killer.

Gutters, Downspouts, and Drainage

Inspectors look at gutters and downspouts. They check that water is directed away from the foundation. Poor drainage causes foundation problems, so this is important.

What to fix: Clean gutters thoroughly. Repair any sagging sections. Ensure downspouts extend at least 4 to 6 feet away from the foundation. If you have grading issues that direct water toward the house, address them. Make sure the grading slopes away from the foundation.

Cost to fix: $200 to $500 for gutter cleaning and repair, $500 to $2,000 for grading adjustments

Cost of not fixing: Foundation and water damage risk. Buyers will be concerned.

Safety and Building Code Issues

Inspectors are looking for safety issues. Decks not properly attached to the house are safety hazards. Stairs with improper riser heights are hazards. Lack of handrails on stairs. Missing smoke detectors. Carbon monoxide detectors not installed.

What to fix: Install smoke and carbon monoxide detectors in all required locations. Repair any loose deck railings or stairs. Ensure stairs meet building code requirements. Fix any obvious safety hazards.

Cost to fix: $50 to $200 for detectors, $500 to $2,000 for deck or stair repairs

Cost of not fixing: Safety issues are non negotiable. Buyers will demand fixes.

Cosmetic Issues Versus Critical Issues

Here’s an important distinction: Some issues are deal killers. Others are cosmetic complaints that don’t need fixing.

Fix These (Critical Issues):

• Roof problems
• Foundation issues
• Water intrusion or mold
• Active plumbing leaks
• Non functioning electrical, heating, or cooling
• Safety hazards

Don’t Fix These (Cosmetic Issues):

• Dated finishes or colors
• Worn but functioning flooring
• Outdated light fixtures (unless they don’t work)
• Cosmetic wear on cabinets or counters
• Scratches, dings, or minor marks
• Outdated appliances that still work

Cosmetic issues are things buyers expect to handle themselves. Critical issues are deal killers. Know the difference.

The Pre Listing Inspection and Fix Checklist

Before you list, get a professional home inspection yourself. This costs $300 to $500 but prevents surprises during the buyer’s inspection. Address any issues the inspector identifies that fall into the critical category.

Your Pre Listing Checklist:

• Get a professional home inspection before listing
• Have a roofing contractor evaluate roof condition
• Have a foundation contractor evaluate foundation if you’ve had any water issues
• Have electrical system professionally evaluated if concerned about age or condition
• Have plumbing system evaluated if you have old pipes or known leaks
• Service your HVAC system
• Clean gutters and verify proper drainage away from foundation
• Install or replace smoke and carbon monoxide detectors
• Fix any active water leaks
• Repair any obvious safety hazards

This takes time and money, but it’s worth every dollar. It prevents the buyer’s inspector from discovering problems that kill deals.

The Bottom Line

Home inspection surprises kill deals. A buyer gets excited about your home, makes an offer, then the inspection reveals a $20,000 roof problem. Suddenly the buyer is asking for credits they don’t have budgeted. The deal falls apart.

The strategic approach: Get ahead of these problems. Know what issues exist before you list. Address critical problems. Demonstrate that you’ve taken care of the home. Give the buyer confidence that they’re not inheriting major headaches.

The investment in fixing critical issues before listing is an investment in your sale. It protects your price. It prevents deal killing negotiations. It gets your home sold faster.
