Experts With Over 40 Years of Experience
Since 1984, we’ve delivered reliable, high-quality electrical work backed by over 40 years of hands-on experience in residential and commercial projects.
Upfront Estimates & Easy Scheduling
Call 860-872-2366 to get started—every installation comes with a clear, detailed estimate so you know the full cost before any work begins.
A lot of installation projects start before anyone checks if the existing system can handle them. Panels run out of space. New appliances don’t have dedicated circuits. Older wiring isn’t built for today’s demand. Across Tolland County, that gap shows up fast when you start adding things.
⬩➤ Wiring not built for modern loads
⬩➤ Panels with no room for new circuits
⬩➤ Installations added without planning
For many homes, it’s not one issue — it’s a buildup of smaller ones. Left alone, they get expensive. Some become dangerous.
We Plan the Work — Not Just the Installation
We plan everything before touching a wire—load calculations, permits, and honest answers about your panel. From South Windsor to Manchester to Glastonbury and Coventry, we handle everything from circuits to full wiring.
Every job starts with a clear estimate. If anything changes, we update it and get your approval — no surprises.
Kitchen & bathroom remodeling serving Tolland County with residential renovation services throughout Ellington, Vernon, Manchester, South Windsor, and surrounding towns, bringing over 20 years of experience to full kitchen renovations, bathroom remodels, and shower installations. Call 860-257-6300 for a free consultation.
Outlets and switches wear out, get wired incorrectly, or end up in the wrong place after a remodel. We handle new outlet installation, switch replacements, and relocations across Vernon and the surrounding towns, making sure everything is safe, properly wired, and placed where you actually need it.
Large appliances and systems need dedicated circuits — running them on shared lines leads to tripped breakers and equipment issues. We size and install dedicated circuits correctly so your electrical system can handle the load without problems or interruptions.
New construction requires every circuit to be planned, roughed in, and finished correctly from the start. We handle full electrical systems across Tolland County, including permit pulling, inspections, and making sure everything is built to code from day one.
Kitchen remodels almost always require new circuits for appliances and countertop outlets. We work with homeowners and contractors in Vernon and Manchester to make sure everything is wired correctly so the project moves forward without delays or rework.
A single power surge can damage your HVAC system, appliances, and electronics in seconds. We install whole-home surge protection at the panel level so your entire electrical system is protected all at once, not just individual devices.
Pool and hot tub wiring has strict code requirements because of the risks involved. We handle dedicated circuits, bonding, GFCI protection, and inspections to make sure everything is installed safely and meets all local electrical codes.
Smoke detectors only protect your home if they’re installed and working properly. We install hardwired smoke and carbon monoxide detectors across Tolland County, including interconnected systems so every alarm sounds at the same time.
The difference between a proper installation and a shortcut usually isn't visible — until something goes wrong.
Permits Protect You Later Work
Work done without permits creates real problems when you sell your home, file an insurance claim, or need future work done — we pull every permit the job requires, no exceptions.
Load Calculations Before Any New Circuit
Adding circuits without accounting for what the panel is already carrying is how you end up with a system that trips constantly or creates fire risk — we run the numbers first every time.
Correct Wire Sizing for the Application
Undersized wire for a dedicated appliance circuit or a well pump doesn't just underperform — it overheats, and that's a fire hazard that builds silently inside your walls.
Materials Warrantied for One Year
We stand behind the materials we install with a one-year warranty — if something fails on our end, we come back and make it right.

As a family-run business, our reputation means everything to us. We show up when we say we will, complete the work properly and safely, and leave your home clean and secure when the job is done—here’s what local homeowners have said about working with us.

Yes, always. Any installation work that requires a permit in Connecticut — new circuits, service work, new construction wiring, pool and hot tub electrical — we pull the permit before we start. It protects you and it's the law. We've been doing this since 1984, and we've never skipped a permit to save time or money.
All costs — labor, materials, and any permit fees that apply to the job. There are no surprise line items after the fact. If the scope of the project changes once we're into it, we re-adjust the estimate and get your sign-off before we do anything additional. Most estimates are ready within a week of our site visit, and there's no charge for the estimate itself.
It happens, especially in older homes around Tolland County. If we open up a wall and find something that changes the scope — deteriorated wiring, undersized circuits, work done wrong by someone else — we stop, explain what we found, and update the estimate before continuing. We've been doing this long enough that we try to anticipate these situations before we start, but when surprises come up, we work through them without leaving you hanging. If needed, we'll work late or on a weekend to keep things on schedule.
Yes. Rosa Electric holds Connecticut Electrical License E1-0184929, and we carry both general liability insurance and workers' compensation coverage. You're protected if anything happens on the job.
