Projects Completed:
-Electric water heater installation
-Circuit breaker panel upgrade
-Electric dryer wiring and connection
From the initial consultation, it was clear I was working with a true professional. They took the time to explain each project in detail, answered all my questions patiently, and provided transparent pricing with no hidden fees.
What stood out most:
The water heater installation was flawless. They ensured everything was up to code, properly grounded, and functioning perfectly. The attention to safety details gave me complete peace of mind.
The circuit breaker upgrade was handled expertly. They assessed my home's electrical needs, recommended the right capacity, and completed the work efficiently while keeping the disruption to my daily routine minimal.
For the dryer connection, they ran wiring cleanly and professionally, ensuring proper voltage and a safe, reliable connection. Everything was tested thoroughly before they considered the job complete.
Throughout all three projects, they maintained a clean work area, showed up on time, and demonstrated exceptional craftsmanship. I'll definitely be using them for all future electrical needs!
Came back from out of town on a Friday evening to find the garage without power.
Jason from Dollens walked me step by step through all the trouble shooting over the phone to spot the issue and resolve it within minutes.
I am going back to them for all my Electrical nees!
Still my go to electrical contractor. On time, plenty of communication, professional.
Converting from propane to an electric BBQ (firewise change).
Needed a new outlet on a 20 amp circuit that had an old 15 amp style socket. These are the guys I trust to keep us safe.
Update 9/2020 - Upgraded some thermostat wiring for me with a difficult routing. Professional and quick.
Update - Jason and Josh again came through for me. In the midst of a heat wave, they were able to come to the other end of the county and fix an electrical problem at my mother's house. Got the outlets for the portable AC and lift chair back working and made the wiring safer to boot.
Original - Could not ask for better. Jason installed a new 40 amp circuit and an EVo charger for our car. (No more slow 110 charging. Yeah!) While working in our breaker panel he noted a dangerous situation left by a previous contractor who upgraded our air conditioning.
(Side note kind of disappointing the inspector didn't notice that the other contractor put in a bigger breaker on a wire that was too small. Luckily the wire insulation had just started to bubble and it didn't catch fire.)
Within a week they were able to fit us in to replace the faulty circuit as well as rewire our garage lighting to eliminate some creative but scary runs of extension cords and re-purposed outlets. Now I have bright lights and when I look up, I don't see wires draped everywhere.
We connected with Jason of Dollens Electric through our equally excellent general contractor Dan Mackey. (Who by the way had nothing to do with the faulty circuit or the creative garage lighting.)
Lastly a thank you to Jason's son Josh who got to do the crawling under the house.
I had a hard time finding a contractor who wanted to install a power meter for dynamic energy monitoring over an expensive DCC. On my first call with them they recommended an Emporia Pro which is the cheapest option for dynamic load management, so I knew that they had the best for the customer in mind. I decided to go with Wallbox's offering instead; although I picked a less common method for dynamic load management Joshua had no issues wiring everything and it was great to see that he took in my input instead of just telling me I had to install a costly DCC. I also liked that he already had a lot of prior experience installing Wallbox's car charger.
Thank you for an amazing install. Support Local!
I was pleased when they briefly reviewed an installation manual to make sure they remembered exactly how the brand worked. It was obvious Joshua already knew how to make the installation but he doubled checked anyway. (I'm glad I'm not the only person who still refers to a manual.)
Call/use them; you won't be sorry.
Excellent communication and professional!
Highly recommend!
Jason seemed to know the possible cause for the problem when I told him that the parts of the house were losing power gradually, and he was right!! He came out on the same day and fixed the problem (burnt crimp in junction box in the garage) within an hour!! Excellent!
They went above board to make sure every thing was done to perfection !
They give an accurate read on what needs
to be done. They are a safety-first company
that shows up energetic & work...
Type 1 vs. Type 2 — we place it where it protects most
- Type 1: ahead of the main overcurrent device (often at service equipment)
- Type 2: on the load side (commonly at the main panel or a major sub-panel)
We choose based on your service equipment, grounding/bonding, conductor routing, and where sensitive loads live. You get the shortest leads, the right overcurrent protection, and a clean, labeled install.
What’s included in our installation

FAQs
Do I still need power strips if I have a whole-house SPD?
A whole-home device handles big spikes. Quality power strips add a second layer for sensitive electronics at the outlet.
Should it go at the main panel or a sub-panel?
We install where it protects the most (often the main). If a large sub-panel feeds a remodel, shop, or EV loads, we may add an SPD there too.
Does this require a permit?
Yes. We handle the permit and meet the inspector.
Will it stop lightning damage completely?
Nothing is absolute. An SPD dramatically reduces risk. Proper grounding and bonding matter too.
How long does installation take?
Typically under two hours once permitted, depending on access and routing.
