Electrical Services We Provide in Hollis, NH
The properties here vary from 18th and 19th-century farmhouses on large rural lots to mid-century homes and some newer construction near the town center. What many share is an electrical system that needs attention — and in some cases, significant updating. We work in all of them, prepared for what older homes typically present.
Electrical Panel Upgrade — Hollis, NH
Older properties here frequently have panels that are decades past their useful life — sometimes original fuse boxes, sometimes 60-amp or 100-amp breaker panels from the 1960s and 70s. These systems were not designed for the electrical load of a modern household. An EV charger alone requires a dedicated 50-amp circuit. Add central air, a home office, and modern kitchen appliances, and you have a panel that’s being pushed well past what it was built for.
We upgrade residential panels to 200-amp service from initial load assessment through final inspection. We coordinate the permit with the Town of Hollis building department and handle everything — you don’t need to manage the paperwork or the scheduling. When the job is done, you have a modern panel, a documented inspection, and the capacity to run your home the way you want.
Signs your panel may need replacing:
- Breakers tripping repeatedly under normal everyday load
- A fuse box still in place rather than a modern breaker panel
- No open slots to add circuits for new appliances or an EV charger
- Lights that dim noticeably when large appliances turn on
- A Federal Pacific, Zinsco, or Pushmatic panel — all have documented safety histories
- Your panel is more than 25–30 years old
The estimate is free. We’ll come out, look at what you have, and give you a straight answer.
Home Rewiring — Hollis, NH
This is one of the most common things we deal with on properties here. Homes built before 1980 — and there are many of them in this area — frequently have knob-and-tube wiring, aluminum branch circuit wiring, or cloth-insulated cables. Each of these creates real risks that insurance companies and home inspectors flag consistently.
Knob-and-tube systems predate grounded circuits and aren’t designed for today’s loads. Aluminum branch wiring expands and contracts differently than copper terminals, causing connections to loosen over time, arc, and generate heat. Insurance carriers in New Hampshire are increasingly refusing to renew policies on homes with unaddressed aluminum wiring, and buyers’ inspectors flag both systems on every sale.
We provide full and partial home rewiring — but we don’t recommend more than what’s genuinely needed. We assess what’s actually in your walls, explain what the risk level is, and rewire only what the situation calls for. If partial remediation is the right answer, that’s what we recommend.
Rewiring services we provide:
- Full house rewiring for pre-1980 properties
- Aluminum branch circuit wiring remediation and replacement
- Knob-and-tube wiring removal and replacement
- Partial rewiring for kitchens, bathrooms, and room additions
- Pre-sale and pre-insurance wiring assessments
- Replacement of deteriorated, overheated, or rodent-damaged wiring in attics and basements
Insurance & Pre-Sale Electrical Assessments
This deserves its own section for homes here, because it comes up often.
Insurance companies are increasingly requiring electrical inspections before issuing or renewing coverage on older properties — particularly those with knob-and-tube or aluminum wiring. If you’ve received a notice from your carrier about your electrical system, or if you’re buying or selling an older home and need a clear picture of what the wiring requires, we can help.
We provide thorough electrical assessments, explain exactly what’s there and what level of risk it presents, and give you a written scope of work covering what would need to be updated — and what doesn’t. No pressure, no upselling. Just honest information and documentation you can provide to your insurer or the other party in a transaction.
EV Charger Installation — Hollis, NH
More residents here are driving electric vehicles, and most are still charging on a standard 120-volt outlet — which means 20+ hours to get a full charge and unnecessary wear on the battery management system. A Level 2 home charger on a dedicated 240-volt circuit brings that down to 4–8 hours overnight.
We handle complete Level 2 EV charger installations — load calculation, dedicated circuit from the panel to the garage, charger mounting, and permit where required. We work with all major EV brands and charging hardware including Tesla Wall Connector, ChargePoint, JuiceBox, and Grizzl-E.
One important note for older properties: we always check panel capacity first. Many homes here don’t have available load headroom for an EV circuit without a panel upgrade. If that’s the case, we’ll tell you upfront and quote both together.
GFCI Outlet Installation — Hollis, NH
New Hampshire code requires GFCI-protected outlets in all kitchens, bathrooms, garages, unfinished basements, crawl spaces, and exterior locations. Many older homes here still have standard two-prong or ungrounded outlets in these areas — a code violation and a genuine hazard.
We install and test GFCI outlets correctly. That means proper line and load wiring so downstream outlets on the circuit are actually protected, not just the visible outlet. A lot of homes have GFCI outlets that were installed incorrectly at some point and provide no real downstream protection at all. We identify and fix that as part of the installation.
Generator Transfer Switch Installation — Hollis, NH
Rural properties lose power more often and for longer than homes in denser areas — and recovery time from the utility is slower when you’re on a quiet country road. Every winter, southern New Hampshire gets hit with storms that knock out power for hours or days. A generator without a proper transfer switch means extension cords through windows and real risk to utility workers from back-fed power on the line.
We install manual and automatic transfer switches for portable and standby generators. The job includes transfer switch sizing, panel interlock or dedicated transfer panel, exterior inlet box mounting, and a full load test before we leave.
Generator connection options:
- Manual transfer switches for portable generators
- Automatic transfer switches for whole-home standby generators
- Panel interlock kits for compatible breaker panels
- Exterior weatherproof generator inlet boxes
- Critical load prioritization for larger properties
Lighting Installation — Hollis, NH
Whether you’re renovating an older farmhouse interior or adding exterior lighting across a larger property, we install residential lighting cleanly and correctly — wired properly, spaced so it functions, and finished without exposed junction boxes or conduit.
Lighting work we handle:
- Recessed lighting in living rooms, kitchens, hallways, and bedrooms
- Under-cabinet kitchen lighting on dedicated dimmers
- Exterior security, flood, and pathway lighting for larger lots
- Motion-sensor and dusk-to-dawn outdoor fixtures
- Barn and outbuilding lighting circuits
- Bathroom vanity and exhaust fan/light combinations
- General fixture replacement throughout the home
Ceiling Fan Installation — Hollis, NH
Older homes here often have ceiling boxes that were sized for a light fixture — not a ceiling fan. Hanging a fan on an undersized box is a code violation, and the vibration and torque of a fan will work it loose over time. We upgrade the box first when needed, then mount and wire the fan with independent controls for fan and light.

Frequently Asked Questions — Electrician in Hollis, NH
Do you work on large properties and older farmhouses here?
Yes, this is a significant part of what we do in this area. We come prepared for the complexity older homes bring: unusual panel configurations, multiple sub-panels, knob-and-tube in hard-to-access areas, and ungrounded circuits throughout. We’ve seen it before.
My insurance company sent a notice about my wiring — can you help?
Yes. This is a common situation for older properties here. We assess the specific issue your insurer flagged, explain what it means and what level of risk it presents, perform the necessary work with proper permits, and provide documentation you can submit directly to your carrier. Call (603) 377-5622 to schedule an assessment.
Is a permit required for electrical work here?
Yes. Panel upgrades, service upgrades, rewiring, and new circuit installations all require permits. We handle the entire permit process — filing, scheduling the inspection, and getting the work signed off by the building department.
What does a panel upgrade cost?
Most residential panel upgrades in this area run $1,500–$3,500 depending on scope and existing service configuration. Older properties sometimes require additional work at the meter or service entrance, which affects cost. We give you a real number after a free on-site assessment.
Can you assess wiring before I buy or sell an older home here?
Yes. We provide pre-purchase and pre-sale electrical assessments — a thorough look at what’s there, what the risk level is, and what would need to be updated. This is useful both for buyers who want to know what they’re getting into and sellers who want to address issues before listing.
