Maintenance

Preventative beats emergency every time. Annual inspections catch loose connections, failing breakers, and rodent damage before they become a 2 AM call in February. Written reports, prioritized findings, and torque-checked connections.

What We Offer

Whole-home electrical inspection

Panel, grounding, bonding, and accessible device inspection with a written report. Recommended every 3 to 5 years, annually for homes 40+ years old.

Thermal imaging and torque checks

Infrared scan of the panel under load to find hot connections before they fail. Torque-check of breaker lugs and neutrals to manufacturer spec.

GFCI, AFCI, and smoke-detector testing

Verify every protective device trips on test, and confirm hardwired smoke and CO detectors are within service life.

Commercial PM programs

Scheduled preventative maintenance for small commercial tenants. We work around your hours and provide documented reports for insurance and compliance.

Why It Matters Here

Preventative beats emergency every time

Minnesota weather is hard on electrical systems. Thermal cycling between -20° and 90° loosens connections, rodents chew insulation in rim joists, and decades-old breakers lose calibration. An annual inspection catches the issues that would otherwise show up as a 2 AM service call in February.

Frequently Asked Questions

Common questions about maintenance in the Twin Cities metro. Don't see yours? Call us at 763-301-4829.

Every 3 to 5 years for homes under 25 years old, and annually for homes 40 years or older, homes with aluminum wiring, or homes that have had a recent insurance claim. Most Minnesota insurers also require an inspection after a major renovation or before a home sale.
We test every breaker under load, thermal-image the panel to find hot connections before they fail, check GFCI and AFCI devices for proper trip, verify grounding and bonding, inspect accessible junctions, and test any smoke and CO detectors that are hardwired. You get a written report with prioritized findings.
Yes. Torque-checking breaker lugs and neutral bars is part of every inspection. Loose connections are the leading cause of panel fires and the easiest thing to catch before they become a problem. We use a calibrated torque screwdriver to manufacturer spec, not a "tight enough" feel.
A comprehensive home electrical inspection runs $250 to $400 for most single-family homes in the Twin Cities metro. You get a written report with prioritized findings. If you book repairs at the same visit, the inspection fee is applied toward the repair cost.
Breakers that trip more than occasionally, outlets or switches that are warm to the touch, flickering lights when an appliance turns on, a panel that buzzes or hums, or any burning or sulfur smell near outlets or the panel. Also: a home over 40 years old that has never had an inspection, aluminum wiring from the 1960s–70s, or a recent insurance renewal asking for a four-point or electrical inspection.
Yes. Pre-sale inspections are common in Minnesota — some lenders and insurers require them for older homes. We provide a written report that meets Minnesota Department of Labor and Industry documentation standards. Pre-purchase inspections give buyers a clear picture of what they are taking on before closing.
Yes. We provide written inspection reports that most Minnesota insurers accept for coverage renewals and four-point inspection requirements. If your insurer has flagged your panel or wiring as a condition of renewal, we can inspect, report, and perform any required remediation as a single appointment.
A thermal camera finds hot spots that look fine to the naked eye. A loose lug on a 60-amp breaker can run 30 to 50 degrees hotter than the surrounding hardware — invisible to the eye, obvious on thermal. That kind of catch prevents panel fires. We include thermal imaging on every panel inspection as standard.
