Aluminum Wiring in Condos: A Board Member's Complete Remediation Guide

If your board just received an insurance non-renewal notice mentioning aluminum branch wiring, this guide walks you through the entire remediation process - from sample inspection through final unit - the way Pirro has run it across nearly 500 units in the DMV.

Condo boards in the DMV are getting the same letter more often every year. It arrives from the master policy carrier, it mentions aluminum branch-circuit wiring, and it gives the association a window - often 12 to 24 months - to remediate or accept a premium that can rise five to ten times the current amount. This guide is written for the board member who has just been handed that letter and is trying to figure out what to do next.

It is based on how Pirro Electric runs full aluminum-to-copper remediation across garden-style and mid-rise condo communities in Montgomery County, Prince George's County, Fairfax County and DC. The first community we did was 256 units in Montgomery Village, over about two and a half years, after two building fires had already occurred. We are now approaching 500 remediated units and we have never skipped a unit in a project - a detail that matters more than it sounds like when it comes to your master policy.

Why aluminum branch wiring is a problem

From roughly 1965 through 1973, copper prices spiked and aluminum was substituted for copper in residential branch-circuit wiring at very large scale. Aluminum expands and contracts more than copper under load, oxidizes differently at terminations, and loosens over time at every screw connection - outlets, switches, breakers, wire nuts, and the panel bus. Loose connections generate heat. Heat starts fires.

Modern aluminum (used properly on service entrance and feeder conductors) is not the issue. This is specifically about pre-1974 single-strand aluminum used for 15A and 20A branch circuits - the outlets, lights, and switches inside the units.

Repair vs. replacement: don't confuse the two

There are two categories of remediation on the market and they are not equivalent.

• Pigtailing - attaching a short copper tail to each aluminum wire at every device using a listed connector such as AlumiConn or COPALUM. This is a repair. It leaves the aluminum in the wall.
• Full replacement - pulling every aluminum branch circuit out and replacing it with copper. This is a permanent fix. It is what Pirro does.

Pigtailing is faster and cheaper. It is also the option most insurers now specifically exclude from acceptable remediation - precisely because the underlying aluminum is still in the wall. Boards that pigtailed in 2015 are getting the same non-renewal letters in 2025. Full replacement is the option that closes the file with the carrier.

The three-phase process

Phase 1 - Free sample inspection

We inspect 5 to 10 representative units across the community - typically one from each floor plan and each building era - and produce a ballpark per-unit price range for the board. This is at no cost. The purpose is to give the board a defensible number to take to reserves, to a lender, or into a special assessment vote.

Phase 2 - Full pre-work inspection of every unit

Once the board approves the project, every unit gets a scheduled inspection. This is where we identify unit-specific conditions - a hoarder unit, a biohazard unit, an unauthorized renovation that hid junction boxes, a unit with a resident on medical equipment that needs continuity planning. We schedule around all of it before crews mobilize.

Phase 3 - Per-unit remediation

Each unit takes roughly three to five days, with the heavy electrical work concentrated in about one day. Residents stay in place. Belongings are covered and protected - we do not require move-outs except in the rare unit that is genuinely uninhabitable during work.

Scope boundary - read this carefully

How boards fund it

• Reserves - some associations have enough reserved capital to cover the full project.
• Bank loan - HOA/condo loans are common; monthly dues cover the debt service.
• Special assessment - often the fastest path; typically stretched over 12 to 36 months.
• Insurance-driven timeline - if the carrier has issued a hard deadline, financing has to match that deadline. Do not wait for the second letter.

What every unit gets

• All branch-circuit wiring replaced with copper.
• New receptacles, switches, and light-switch plates throughout.
• New breakers and, where needed, a new panel inside the unit.
• Kitchen, bath, laundry and exterior circuits brought up to current AFCI/GFCI code.
• Final inspection with the AHJ (authority having jurisdiction) and a permit card for the file.

Why 'every unit, no exceptions' matters to the master policy

Carriers want to close the file on the whole property. If even one unit is skipped - a resident who would not let crews in, an owner who moved during the project, a unit under separate renovation - the carrier can (and increasingly does) hold the entire remediation credit until the last unit is done. We build unit-completion tracking and owner-communication cadence into every project specifically to prevent this.

Timeline

A 100-unit community typically runs 6 to 12 months from contract signature to last unit. A 250-unit community typically runs 18 to 30 months. Bigger crews shorten the calendar but not linearly - resident coordination, not electricians, is usually the constraint.
