Mobile's older homes run on wiring their builders never imagined carrying today's loads. We replace knob-and-tube and remediate aluminum wiring the right way — room by room, permits and inspections included, with your insurance company satisfied at the end. Free estimates.
Call (251) 680-7500 Request a QuoteBehind the plaster of a Midtown bungalow or the paneling of a 1970 ranch, the wiring is often the original equipment — installed for a house that ran a radio, a range, and a few lamps. That same wiring now feeds central air conditioning, a modern kitchen, and a device on every outlet. The result shows up as flickering lights, warm switch plates, tripping breakers — and increasingly, as a letter from your insurance company.
Professional Systems has rewired homes across Mobile County and Baldwin County for more than 20 years — in the last year or so we've rewired a historic home on Church Street top to bottom, brought a fire-damaged house in west Mobile back from bare studs, and taken on the saltiest job in the book: rewiring a pier and its boat slips end to end down at Orange Beach. A few things stay true across all of them: full knob-and-tube replacements in the historic districts, aluminum wiring remediation in the '60s and '70s neighborhoods, and everything between. Licensed, permitted, inspected — and planned so you can keep living in your house while the work happens.
Free, no-obligation estimates. Exact pricing in writing before any work begins.

Knob-and-tube was the standard when Midtown, Oakleigh, and the DeTonti Square district were built — ceramic knobs, air-cooled copper runs, and no ground wire anywhere. It was fine engineering for 1935. The problems are what the decades did to it:
The fix is replacement — done carefully, it preserves the plaster and the character while giving the house grounded, code-current circuits.
For about eight years, copper prices pushed builders to wire homes with aluminum branch circuits — and huge swaths of West Mobile, Tillmans Corner, and Prichard's ranch housing went up in exactly that window. Aluminum conducts fine; the problem is what it does at connections. It expands and contracts more than copper, it oxidizes, and over decades the terminations at outlets, switches, and fixtures loosen — creating resistance, heat, and a documented fire risk that insurers and home inspectors flag on sight.
Aluminum has options short of a full rewire, and we'll tell you honestly which your home needs. Approved connector remediation (pigtailing every aluminum-to-device connection with rated connectors) satisfies many insurers at a fraction of rewiring cost; a full copper rewire is the permanent answer, and often the right call when the panel, grounding, and capacity need work anyway. The assessment is free, and the difference between the two paths is exactly the kind of thing you want a licensed electrical contractor — not a sales script — to walk you through.
Lights that dip when the AC or microwave kicks on point to circuits running at their edge — or connections losing their grip.
Heat at an outlet or switch is resistance at a connection. Treat this one as urgent — call the same day.
The visible signature of ungrounded wiring — and adapters don't fix what isn't behind the wall.
Constant trips mean overloaded or failing circuits. Resetting them daily is a symptom, not a solution.
Four-point inspections flag K&T and aluminum by name. A quote from us turns that letter into a solved problem.
Opening walls for a kitchen or addition is the cheapest moment a rewire will ever have. Sequence it right and save thousands.
Manufactured homes have their own rewiring story: aluminum branch wiring is common in older units, connections loosen with transport and settling, and undersized original circuits struggle with modern space heaters and window units — a combination that shows up in insurance inspections across Mobile and Baldwin County's manufactured home communities. We rewire and remediate manufactured homes to the same permitted, inspected standard as site-built houses, and we'll tell you honestly when a targeted repair beats a full rewire.
If an insurer or park inspection has flagged your home's wiring, call — the assessment is free and the letter usually has a fixable answer.
The honest framework: rewiring cost scales with square footage and circuit count, access (an open attic and crawl space make a dramatically easier job than finished ceilings on slab), what's being replaced (full knob-and-tube replacement is the deepest scope; aluminum remediation can be far lighter), and whether the panel and service come along in the same project. A 1,200-square-foot bungalow with attic access and a 2,800-square-foot two-story on slab are entirely different undertakings — which is why we don't quote ranges off a phone call.
What we promise instead: a free on-site assessment, the exact price in writing before work begins, financing options that spread a safety project into manageable payments — and the insurability, resale readiness, and peace of mind that make rewiring one of the few renovations that pays you back in ways you can't see. See everything we do if you're planning a bigger project around it.
Every rewiring project here starts with knowing what decade built the house. The raised cottages of Midtown, Oakleigh, and DeTonti Square carry knob-and-tube behind original plaster — work that rewards patience and punishes shortcuts. The ranch belts of West Mobile, Theodore, and Tillmans Corner hold the 1965–73 aluminum era. Across the bay, Daphne and Fairhope mix both with salt-air corrosion at panels and meter cans. We've rewired in all of it, and we plan each project for the house it actually is.
Professional Systems is headquartered at 216 E I-65 Service Rd N in Mobile, serving the full metro on both sides of the bay.
It scales with square footage, circuit count, access (attic and crawl space vs. finished ceilings on slab), and whether the panel comes along in the same scope. Full knob-and-tube replacement is the deepest project; aluminum remediation can be far lighter. We quote the exact price in writing after a free on-site assessment — and financing is available.
Most single-family rewires run several days to about two weeks depending on size and access. You'll get a written timeline with your quote, and we sequence the work room by room so the disruption stays contained.
Almost always, yes. We keep power on outside the active work zone, restore circuits each evening, and schedule the noisiest work around your household. It's a construction project, but it's not a move-out.
Less than most homeowners fear. Experienced crews fish new wire through attics, crawl spaces, and wall cavities, keeping openings small, strategic, and cut cleanly for easy patching. In historic plaster homes we plan access points to preserve original surfaces wherever possible.
You're in the most common rewiring scenario we see. We assess what's actually active (some homes have partial legacy wiring that's already dead), quote the replacement in writing, and provide the permit and inspection documentation carriers ask for. Most insurers are satisfied once active K&T is professionally replaced.
No. Approved connector remediation — properly pigtailing every aluminum-to-device connection with rated connectors — satisfies many insurers at a fraction of the cost. A full copper rewire is the permanent solution and often makes sense when panel or capacity work is due anyway. We'll show you both paths with real numbers.
Age is the first clue: pre-1950 suggests knob-and-tube; 1965–73 suggests aluminum branch wiring (look for "AL" stamped on cable sheathing at the panel). Ceramic knobs visible in the attic are a giveaway. An electrical inspection settles it definitively.
Yes — aluminum remediation and full rewires for manufactured homes across Mobile and Baldwin County, permitted and inspected, including the insurance-driven projects that park and carrier inspections trigger.
Often, yes — a home with K&T or aluminum branch wiring frequently has a panel of similar vintage. Doing both in one project means one permit, one inspection, and a clean end-to-end system. We evaluate the panel in every rewiring assessment and quote it separately so you can decide.
Old wiring is one of the great deal-killers in home sales — it surfaces in every inspection and gives buyers leverage or cold feet. A documented, permitted rewire converts that liability into a selling point, and keeps the insurance question from sinking a closing.
