Frank A. Dermer Electric & Plumbing in Baltimore: Licensed Two-Trade Shop for Residential Repairs and Upgrades
Frank A. Dermer Electric & Plumbing is a licensed, single-location electrical and plumbing contractor serving Baltimore homeowners and small commercial clients. The business handles routine electrical work—outlet and switch replacement, panel upgrades, lighting installation—alongside plumbing repairs and fixture work, positioning itself as a practical choice for owners who need both trades on one call rather than scheduling separately.
What Frank A. Dermer Actually Is
This is a dual-trade operation, meaning the same company holds both electrical and plumbing licenses and can legally perform permitted work in each discipline. That structure matters: it eliminates the need to coordinate two separate contractors for jobs that touch both systems, such as kitchen or bathroom renovations, or for older homes where electrical and plumbing upgrades often occur in the same project window. The shop operates as a service-call business, taking residential and light commercial jobs on a scheduled or emergency basis, rather than selling retail products or maintaining a showroom.
Services and Pricing
Frank A. Dermer performs standard electrical work including circuit additions, panel upgrades, outlet and switch installation, lighting upgrades, and code-compliant repairs. Plumbing services include faucet and fixture replacement, drain cleaning, leak repair, and water heater service. Pricing is typically quoted per job after a site visit; the company does not publish fixed rates online. Verify current rates and availability by calling directly, as labor costs and material prices shift seasonally and with project scope.
Emergency or after-hours service availability should be confirmed at the time of inquiry. Many Baltimore electricians and plumbers charge a diagnostic or service-call fee (commonly $75 to $150) that applies toward the final bill if work is booked same-day or within a short window; confirm whether Frank A. Dermer follows this model.
How It Compares to Other Baltimore Options
A two-trade license is relatively uncommon in Baltimore's residential service market. Most homeowners use separate licensed electricians (Petry Electric, Jaco Heating & Air, or independent practitioners) and separate plumbers (Calvert Plumbing, Joe Ewing Plumbing) to handle each discipline. The advantage of Frank A. Dermer is coordination and a single point of contact; the disadvantage is that specialists may offer deeper expertise in one trade. If your project is primarily electrical with light plumbing (or vice versa), a single-trade specialist may be faster and more cost-efficient. If you need both trades in the same space, Frank A. Dermer eliminates the scheduling complexity.
Baltimore also has larger multi-trade home-service companies (such as ServiceMaster or franchise HVAC-plus-plumbing shops), which offer faster response times and 24/7 availability but typically charge premium rates and may rely on less experienced staff. Frank A. Dermer, as a smaller, locally rooted operator, generally attracts owners prioritizing direct relationships and straightforward pricing over corporate convenience.
Who This Fits and Who It Doesn't
Frank A. Dermer suits owners with older homes requiring both electrical and plumbing work, or renovation projects that touch both systems. It also fits small commercial clients (offices, clinics) needing reliable, licensed contractors without the overhead of hiring two separate firms. The business does not suit customers requiring extensive design consultation, new-construction supervision on large projects, or 24/7 emergency dispatch. It is not a retail outlet for fixtures or electrical supplies.
What to Expect on Your First Visit
Contact the business directly with a description of the work (e.g., "kitchen remodel, need new outlets and under-sink plumbing," or "water heater replacement and bathroom lighting"). The shop will schedule a site visit at a mutually convenient time. A technician will assess the job, identify any permit requirements (electrical panel work and plumbing modifications in kitchens and bathrooms typically require permits in Baltimore), walk through scope and timeline, and provide a price estimate. If you accept, the company will handle permit applications if needed and schedule the work. Payment terms and warranty coverage should be clarified upfront.
Hours, Parking, and Logistics
Verify hours of operation and whether the business accepts online scheduling or requires a phone call. Most Baltimore electrical and plumbing contractors operate Monday through Friday, 8 a.m. to 5 p.m., with limited weekend or emergency availability; Frank A. Dermer's specific schedule should be confirmed directly. As a service business, it does not maintain public parking or a walk-in retail space.
Frank A. Dermer occupies a practical niche in Baltimore's residential repair market: it reduces friction for owners juggling multiple trades by consolidating licensing and scheduling under one roof. For homeowners tackling multi-system projects, that simplification justifies the call.
