Even if your Houston home has passed city code inspections, it can still harbor serious hidden defects. A professional new‑construction inspection by ARC Inspection Group helps you catch problems early—before you sign closing papers or move in. Here are six of the most common issues inspectors find in new builds and why they matter.
1. Improper Grading and Drainage
In Houston’s heavy‑rain climate, how the soil slopes around your foundation is critical. Many new builds have flat or negative grading instead of the required slope away from the house, which directs water toward the foundation instead of away from it.
Over time, this can lead to:
-
Basement or crawlspace leaks
-
Foundation movement and cracking
-
Soil erosion and landscape damage
An independent inspector checks surface grading, swales, gutters, and downspout discharge points to flag drainage risks before they become costly repairs.
2. Siding and Exterior Flashing Defects
Siding—especially brick, stucco, and fiber‑cement—often looks “finished” but conceals installation flaws. Common issues include missing or incorrectly installed flashing, gaps at corners, loose panels, and poor integration with windows and doors.
When siding or flashing fails:
-
Water can seep behind the walls, causing rot, mold, and termite‑friendly conditions.
-
Energy efficiency drops as air leaks increase around poorly sealed joints.
A thorough inspection tests seams, caulking, trim alignment, and moisture‑entry points to ensure the envelope protects instead of leaks.
3. Electrical System Shortcuts
Electrical work is one of the most frequent defect categories in new construction. Even after a city‑approved rough‑in and final, inspectors still find:
-
Open grounds or reversed polarity at outlets
-
Loose junction‑box connections and overcrowded panels
-
Missing or incorrect GFCI/AFCI protection in required areas
-
Temporary or “builder‑grade” wiring left in place
These issues can:
-
Create fire hazards or trip hazards at the panel
-
Trip breakers frequently or fail to protect sensitive circuits
A professional inspection uses a plug‑in tester and visual checks to confirm that the electrical system is not just code‑passed, but properly installed and safe.
4. Deck and Balcony Construction Flaws
In Texas, decks are high‑use features: for entertaining, drying laundry, or catching a breeze. Yet many new decks have:
-
Improper post‑to‑ledger connections
-
Missing or undersized structural fasteners and joist hangers
-
Loose, non‑continuous, or missing handrails
-
Inadequate or missing diagonal bracing
These flaws can compromise safety, especially on elevated decks more than 30 inches above grade. A structural‑focused deck inspection by ARC Inspection Group evaluates:
-
Ledger attachment to the home
-
Joist span and support
-
Guardrail height and graspability
-
Footing depth and corrosion resistance
5. HVAC and Ductwork Issues
Builders often rush HVAC rough‑ins to hit deadlines, leading to problems like:
-
Poorly sealed or disconnected ducts
-
Incorrectly sized equipment or undersized returns
-
Leaky condensate lines or poorly sloped drip pans
These defects reduce comfort, increase energy bills, and strain the system prematurely. A new‑construction inspection checks:
-
Duct sealing and support
-
Proper filter access and return air pathways
-
Thermostat operation and emergency‑shutoff testing
6. Incomplete Finishes and “Cosmetic” Defects
After the big‑ticket items, inspectors often find half‑finished work:
-
Missing trim, uneven paint, or poorly caulked showers
-
Doors and windows that don’t operate smoothly
-
Loose cabinet hardware or missing hardware
-
Missing handrails or guardrails
These may seem minor, but they can signal sloppy workmanship overall and may cover deeper issues such as:
-
Poor framing or drywall prep
-
Misaligned windows or doors that leak over time
A professional inspection walks every room, opening and closing every door, checking elevations, and documenting all items that should be corrected before or at closing.
Why a “Code‑Passed” Home Still Needs a Professional Check
City code inspections are important, but they:
-
Are often done in stages (slab, rough‑in, final) with limited re‑checks.
-
Are not continuous, so errors can be introduced after the inspector leaves.
-
Focus on minimum code compliance, not best practices or long‑term durability.
A private, independent inspection by ARC Inspection Group gives you:
-
A full‑home, buyer‑focused walkthrough before you close.
-
A written report itemizing defects by priority and location.
-
A clear picture of what the builder should correct before you move in.
In Houston’s humid, flood‑prone environment, a new‑construction inspection is not an extra cost—it’s insurance against future foundation repairs, mold remediation, and safety liabilities brought on by overlooked grading, siding, electrical, and deck issues.
