How to Inspect Exposed Wiring — Georgetown, Delaware

Complete checklist with climate-adjusted recommendations for Georgetown, Delaware

Overview

Check attic, basement, and garage for damaged insulation, improper splices, or wiring chewed by rodents. Exposed or damaged wiring is a leading cause of electrical fires.

DIY FriendlyModerate~45 min

Step-by-Step Guide

1

Prepare to inspect safely

Put on safety glasses, a dust mask (especially in attics), long sleeves, and sturdy shoes. Bring a bright flashlight or headlamp. Do not touch any wiring during the inspection — this is a visual-only assessment. If you want to test for live wires, use a non-contact voltage tester held near (not touching) the wire.

2

Inspect the basement and crawl space

Examine wiring running along floor joists, through holes in framing, and to the electrical panel. Look for wires hanging loosely (they should be stapled or secured to framing every 4.5 feet), bare copper where insulation has been stripped or degraded, black scorch marks on wood near wires, and improperly supported cable runs.

3

Check for improper splices and junction boxes

All wire connections (splices) must be enclosed inside a covered junction box — this is code in every jurisdiction. Look for wires twisted together and wrapped in electrical tape without a junction box (common DIY shortcut and fire hazard). Open junction boxes should have covers installed. All boxes should be accessible, not buried behind drywall.

4

Look for rodent damage

Rodents gnaw on wire insulation for nesting material, exposing bare copper conductors. Look for teeth marks, shredded insulation, droppings near wiring runs, and nesting material (shredded paper, insulation, leaves) near electrical cables. Rodent damage is especially common in attics, crawl spaces, and garages. A chewed wire with exposed conductor against wood framing is an immediate fire risk.

5

Inspect the attic

Walk carefully on joists or plywood walkways (never step on drywall between joists). Examine wiring for heat damage from proximity to recessed lighting cans, degraded insulation from attic heat, and old knob-and-tube wiring (porcelain insulators with individually run hot and neutral wires). If you find knob-and-tube, it needs professional evaluation.

6

Check the garage and exterior

Inspect wiring in the garage for physical damage from being bumped, pinched by stored items, or run through areas where it can be snagged. Outdoor wiring should be in weatherproof conduit (rigid or flexible). Look for wiring exposed to the elements, UV-degraded cable jackets (brittle, cracked), and outdoor junction boxes without weatherproof covers.

7

Assess wire type and age

Identify the wiring type: NM-B (Romex) with a plastic jacket is standard modern wiring. BX/AC has a flexible metal armor. Knob-and-tube (pre-1950) uses ceramic insulators. Cloth-covered wiring (1920s-1960s) has fabric insulation that deteriorates with age. Aluminum wiring (1965-1973) requires special connectors. Note what you find — older wiring types have specific risks.

8

Document and report findings

Take photos of any damage, improper splices, rodent evidence, or concerning wiring conditions. Note the location of each finding (e.g., 'attic, above master bedroom, near recessed light'). Create a priority list: exposed bare conductors and rodent damage are urgent; missing junction box covers are important; old wiring type documentation is for long-term planning.

What You'll Need

Tools

  • - Bright flashlight or headlamp
  • - Non-contact voltage tester
  • - Phone or camera for documentation
  • - Safety glasses
  • - Dust mask

Cost Estimates

DIY Cost

$0 (inspection only)

Professional Cost

$100 - $300 (spot repair per location); $8,000 - $20,000 (full rewire for knob-and-tube or aluminum)

Safety Tips

  • This is a VISUAL inspection only — do not touch, move, or manipulate any wiring.
  • Use a non-contact voltage tester to detect live wires before getting close.
  • In the attic, step only on joists or walkway boards — never on the drywall ceiling, which will not support your weight.
  • Wear a dust mask in attics and crawl spaces to avoid inhaling fiberglass insulation, dust, or rodent contaminants.
  • If you find active sparking, burning, or melted wiring, leave the area and turn off the main breaker at the panel before doing anything else.

When to Call a Professional

Call an electrician for any exposed bare conductors, rodent-chewed wiring, open splices without junction boxes, knob-and-tube wiring, cloth-covered wiring, aluminum wiring, or any signs of heat damage or scorching. These are not DIY fixes — improper electrical repairs cause fires.

Pro Tip

If you are buying or selling a home, insist on a dedicated electrical inspection (separate from the general home inspection) if the home was built before 1975. General home inspectors often miss wiring issues in hard-to-access areas that a licensed electrician would catch.

Common Mistakes to Avoid

  • Touching wires during a visual inspection — even 'dead' wires can be live on a different circuit than you expect.
  • Covering improper splices with more electrical tape instead of installing proper junction boxes.
  • Ignoring rodent droppings near wiring — where there are droppings, there is likely chewing damage nearby.
  • Blowing insulation over old wiring without inspecting it first, hiding problems and creating fire risk.
  • Assuming that because the lights work, the wiring must be fine — damaged wiring can function while being a fire hazard.

How to Test GFCI Outlets

Press the test button — the outlet should click off. Press reset to restore. GFCI outlets protect against electrocution and should be tested monthly.

How to Check for Warm or Discolored Outlets

Feel all outlets and switch plates. Warmth, discoloration, or buzzing indicates a wiring problem that could lead to an electrical fire.

How to Inspect Your Electrical Panel

Look for rust, scorch marks, or a burning smell. Check that breakers are properly labeled. The electrical panel is the heart of your home's electrical system.

How to Check for Overloaded Circuits

Look for tripping breakers, flickering lights, or warm extension cords. Overloaded circuits are a leading cause of residential electrical fires.
