There is a specific charm to Westover that is difficult to quantify but unmistakable when you walk its streets — the proportions of the 1930s and 1940s bungalows, the mature tree canopy, the neighborhood commercial strip that has been there since before most of its current residents were born. It is also one of the most electrically vulnerable neighborhoods in Arlington County, and the charm is part of why that vulnerability persists. When a house looks this good on the outside, it takes real intention to ask hard questions about what is happening inside the walls.
Why Westover’s Character and Its Electrical Risk Are Related
Westover was developed primarily between 1935 and 1950 — a construction era that produced homes with genuine architectural character, solid construction, and electrical systems that reflect the knowledge and materials of that moment in time. The knob-and-tube wiring installed in Westover’s original homes was correctly designed for the electrical loads of 1940. It was not designed to be supplemented decade by decade by additions, renovations, and appliance upgrades that collectively represent ten times the original anticipated load on conductors whose insulation has been degrading since before the Korean War. The charm of a Westover bungalow is genuine. The insulation on its original wiring is not.
What Knob-and-Tube Wiring Looks Like After 80 Years in a Westover Home
A thorough attic inspection in a Westover home that has not been rewired reveals a consistent picture. The ceramic knobs that support the conductors are still in place — ceramics last essentially indefinitely. The conductors themselves are still continuous — the copper does not degrade in the way that insulation does. What has changed is everything that surrounds and protects those conductors. The original rubber insulation has dried and cracked at every point of contact, flexion, or thermal stress. In many homes, insulation was added to the attic at some point in the previous 40 years, and the knob-and-tube conductors were buried in it — creating exactly the heat retention condition the NEC specifically prohibits and that fundamentally changes the thermal operating environment of a conductor designed to cool through air convection. The overcurrent protection on those circuits — fuses or early breakers — may have been upsized at some point to stop nuisance trips, removing the last functional safety constraint from conductors that are already operating beyond their design parameters.
The Specific Conditions That Make Westover Knob-and-Tube an Active Risk
- Attic insulation added at any point over the original knob-and-tube without conductor clearance
- Splices made outside junction boxes connecting modern circuits to original wiring
- Fuses replaced with higher-amperage units to stop tripping from aging conductors
- Original conductors visibly cracked or missing insulation at any accessible point
- Modern high-draw appliances on circuits that originate from original knob-and-tube wiring
- Any prior electrician who opened walls and reconnected rather than replaced the knob-and-tube they found
The Westover Premium and the Insurance Reckoning
Westover homes sell at prices that reflect their architectural character, their neighborhood walkability, and their proximity to East Falls Church Metro and Bluemont Park. What those prices also attract is increased scrutiny from insurance underwriters who are now specifically inquiring about knob-and-tube wiring in Arlington County’s pre-war housing stock. An insurer who discovers active knob-and-tube wiring in a Westover home during a policy review — which often happens at refinancing, at resale, or at policy renewal — has several options: coverage continuation with an electrical exclusion, a remediation requirement with a 30-to-60-day deadline, or policy non-renewal. A Westover homeowner who proactively commissions an assessment and completes remediation before any of those triggers arise has control over the process. One who discovers the requirement in the middle of a refinancing closing does not.
The Rewiring Conversation Every Westover Buyer Should Have Before Closing
Buyers of Westover properties who are competing in Arlington County’s heated market frequently waive inspection contingencies to strengthen their offers. The consequence of waiving inspection on a pre-1950 Westover property is accepting an unknown electrical history without any basis for negotiation. A buyer who can access the property for a two-hour pre-offer electrical walk-through by PRO Electric plus HVAC — even without a full inspection contingency — can assess whether the electrical system is a $5,000 correction or a $40,000 rewiring before the offer price is set. In a market where $40,000 represents real money even at Westover’s price points, that assessment is worth the two hours it takes.

Low-Impact Rewiring in Westover: What It Looks Like in Practice
A Westover bungalow rewire does not have to mean opening every wall in the house. The most efficient approach — the one PRO Electric plus HVAC uses in these properties — combines attic and basement access for the longest conductor runs, selective wall openings at locations where access serves multiple circuits simultaneously, and surface conduit in utility and service areas where wall fishing is not practical. The goal is complete, code-compliant, inspected wiring on every circuit in the home — without leaving the interior looking like it was rewired. These homes are worth protecting. The care with which PRO Electric plus HVAC approaches the work reflects that.
Serving Westover, Lyon Village, Bluemont, and All of Arlington County
PRO Electric plus HVAC assesses and rewires Westover’s pre-war homes with low-impact methods that respect the character of these properties — Arlington County permits, post-remediation insurance documentation, and work that holds up to inspection.

Frequently Asked Questions
Why are older Westover homes at higher electrical risk?
Many Westover homes were built between 1935 and 1950 and still contain original or partially updated wiring systems. These homes often have knob and tube wiring, aging insulation, and decades of added electrical demand that the original system was never designed to support.
What makes knob and tube wiring dangerous after 80 years?
Knob and tube wiring becomes dangerous when the original insulation dries out, cracks, or is disturbed during renovations. It is especially risky when buried under attic insulation, spliced improperly into newer wiring, or connected to modern high demand appliances that exceed its intended load.
Can insurance companies deny coverage because of knob and tube wiring?
Yes. Insurance companies may impose exclusions, require remediation within a short deadline, or refuse to renew coverage if active knob and tube wiring is found in a home. This often becomes an issue during refinancing, policy renewal, or a home sale.
Should Westover buyers get an electrical assessment before closing?
Yes. A pre offer or pre closing electrical assessment can help identify whether the home needs minor corrections or a major rewiring project. This allows buyers to understand the real electrical condition before committing to the purchase price.
Does rewiring a Westover bungalow require tearing open every wall?
No. A well planned rewire often uses attic and basement access, selective wall openings, and surface conduit in utility areas to minimize disruption. The goal is to install complete code compliant wiring while preserving the character and appearance of the home.
