What to Expect from Our Aluminum Wiring Replacement Service
Aluminum branch circuit wiring was used in approximately 2 million homes built between 1965 and 1973 as a cheaper alternative to copper during a period of high copper prices. Unfortunately, aluminum wiring has proven to be a significant fire hazard -- the Consumer Product Safety Commission (CPSC) reports that homes with aluminum wiring are 55 times more likely to have fire-hazard conditions than homes with copper wiring. The problem stems from aluminum's tendency to oxidize, expand and contract at a different rate than copper and steel connections, and develop loose connections that overheat and arc over time. AJ Long Electric provides professional aluminum wiring remediation throughout the DMV — Northern Virginia, Washington DC, and Maryland. We offer two proven remediation approaches: complete rewiring with copper (the gold standard) or COPALUM crimp connections at every junction point, which is the only repair method recommended by the CPSC. Our licensed electricians inspect every outlet, switch, junction box, and connection point in your home, identifying all aluminum wiring locations and assessing their condition. We then perform the selected remediation method throughout the home, ensuring every connection is safe, secure, and code-compliant. This is one of the most important safety upgrades you can make to a home with aluminum wiring. In Bethesda, we have seen how comprehensive renovation electrical for high-end projects affects homeowners. That is why we take the time to assess your entire electrical system and recommend solutions that address both immediate needs and long-term reliability. Every aluminum wiring replacement project we complete in Montgomery County includes a thorough inspection, detailed documentation, and our commitment to your complete satisfaction.

Aluminum Wiring Replacement Questions from Bethesda Homeowners
Is aluminum wiring dangerous?
Yes. The CPSC reports that homes with aluminum wiring are 55 times more likely to have fire-hazard conditions at connections. Aluminum expands and contracts more than copper, causing connections to loosen over time. These loose connections overheat, arc, and can start fires behind walls where you cannot see them.
What is the COPALUM crimp method?
COPALUM is a specially designed crimp connector that permanently joins aluminum wire to a short copper pigtail using a powered crimping tool. The CPSC considers COPALUM the only acceptable repair method short of complete rewiring. The crimp creates a cold-welded connection that will not loosen or oxidize over time.
How much does aluminum wiring remediation cost in Northern Virginia?
COPALUM crimp remediation typically costs $50-$75 per connection point, totaling $3,000-$6,000 for an average home. Complete copper rewiring costs $8,000-$20,000 depending on home size and accessibility. We provide detailed quotes after a thorough inspection of your home's wiring.
Can I just use purple wire nuts instead of COPALUM?
While purple Ideal Twister AL/CU wire nuts are sometimes used, the CPSC does not recommend this method as a permanent repair. AlumiConn connectors and COPALUM crimps are the only connections the CPSC recognizes as safe permanent repairs for aluminum wiring. We use CPSC-recommended methods exclusively.
Will my insurance company require aluminum wiring repair?
Many insurance companies in Virginia either refuse to insure homes with unrepaired aluminum wiring, require remediation within a specified timeframe, or charge significantly higher premiums. After remediation, we provide documentation that you can submit to your insurer for updated coverage terms.

Whole-Home COPALUM Remediation in 1972 Colonial
colonialChallenge
The homeowners were selling their four-bedroom colonial and the buyer's home inspection flagged aluminum branch circuit wiring throughout the house. The buyer's lender required remediation before closing, giving the sellers a 45-day deadline. Multiple outlets showed signs of overheating with discolored cover plates.
Solution
AJ Long Electric performed a complete COPALUM crimp remediation of all 87 aluminum-to-copper connection points in the home. We worked room by room over two days, crimping every outlet, switch, and junction box connection with CPSC-approved COPALUM connectors and documenting each one photographically.
Result
The home passed re-inspection and the sale closed on time. The buyers received a lifetime warranty on all COPALUM connections, and the sellers avoided a $15,000 price reduction that the buyer had initially demanded in lieu of remediation.
Aluminum Wiring Discovery During Kitchen Renovation
townhomeChallenge
During a kitchen remodel, the contractor discovered aluminum branch circuit wiring behind the walls. The homeowner's insurance company was notified and gave a 90-day ultimatum to remediate all aluminum wiring or face policy cancellation. The three-level townhome had aluminum wiring on all three floors.
Solution
We performed COPALUM crimp remediation on 64 connection points across all three levels. For the kitchen circuits being exposed during renovation, we replaced the aluminum wiring entirely with new 12-gauge copper Romex, adding dedicated 20-amp circuits for the new appliances and GFCI protection at the countertop outlets.
Result
The insurance company accepted our remediation documentation and renewed the policy at standard rates, saving the homeowner approximately $1,200 per year in elevated premiums. The new kitchen circuits now safely support modern appliance loads.
Complete Copper Rewire of 1970 Split-Level
split-levelChallenge
A family purchased a split-level home knowing it had aluminum wiring, planning to renovate extensively. Two outlets in the family room had visible scorch marks, and the home inspector found evidence of amateur repairs using standard copper wire nuts on aluminum connections -- a dangerous combination that accelerates overheating.
Solution
AJ Long Electric performed a complete copper rewire of the entire home, replacing all aluminum branch circuits with 12-gauge and 14-gauge copper Romex. We upgraded the panel from 100 amps to 200 amps, added AFCI protection for all living spaces, and installed dedicated circuits for the kitchen, laundry, and home office.
Result
The home now has a completely modern wiring system with no aluminum wiring remaining. The new 200-amp panel provides ample capacity for the family's planned additions including a hot tub and Level 2 EV charger.
Aluminum Wiring Remediation in Luxury Estate Before Sale
estateChallenge
The owners of a 5,200 sq ft estate were preparing to list the property at $1.8 million. Their real estate agent insisted that unaddressed aluminum wiring would deter buyers and could reduce offers by $30,000-$50,000. The home had 142 aluminum-to-copper connection points across two levels plus a finished basement.
Solution
We completed a full COPALUM crimp remediation over three days, addressing all 142 connections throughout the home. We also replaced the original 1969 panel with a modern 200-amp Square D panel and added whole-house surge protection. Every connection was photographed and cataloged in a professional remediation report.
Result
The property sold within two weeks at asking price. The remediation report and lifetime COPALUM warranty were highlighted in the listing and gave buyers confidence in the electrical system's safety.

Aluminum Wiring Replacement in Bethesda by Housing Type
Different home styles have unique electrical characteristics. Select your housing type to see specific considerations.
Colonial Homes
Common Issues
Special Considerations
Colonial homes in Vienna, McLean, and Oakton built during the aluminum wiring era typically have 80-120 connection points. The two-story layout means wiring runs through floor cavities between levels, and junction boxes may be concealed behind finished basement ceilings. COPALUM remediation is particularly effective for colonials since it addresses every connection point without requiring the wall access that a full rewire demands.
