A faulty or outdated light switch is more than an inconvenience — it can be a safety hazard. Our licensed electricians handle all types of switch work quickly, safely, and to NEC code.
Switch: Installation & Replacement
Single-pole, 3-way, GFCI, and specialty switches for any room in your home or business.
✓ Installation of new light switches (single-pole, 3-way, 4-way)
✓ Replacement of damaged, flickering, or sparking switches
✓ Upgrade to decora-style or rocker switches

✓ Troubleshooting wiring issues behind the switch
✓ Code-compliant work with proper grounding
💡 Pro Tip (2026): Smart switches with voice control compatibility (Amazon Alexa, Google Home, Apple HomeKit) are now standard upgrades. Ask us about no-neutral wire smart switch options for older Colorado homes.
Dimmer switches reduce eye strain, set the perfect mood, and can cut your lighting energy use by up to 80%. Not all dimmers work with LED bulbs — we make sure you get the right match the first time.
Dimmer: Installation & Replacement
LED-compatible dimmer solutions for any fixture type — single location, 3-way, and smart dimmers.

Many older dimmer switches are rated for incandescent bulbs only. When used with LED lights, they cause flickering, buzzing, and premature LED failure. In 2025–2026, with Colorado’s push toward energy-efficient lighting, we recommend upgrading to an LED-rated TRIAC dimmer or a smart dimmer with trailing-edge technology.
💡 2026 AI-Assisted Lighting Tip: AI-powered smart dimmers now learn your daily schedule and auto-adjust lighting levels without manual input. Systems like Lutron Caseta and Leviton Decora Smart are top choices we install and configure.

Before any fixture goes in, proper lighting design ensures your space has the right foot-candles, color temperature, and uniformity. We use DIALUX EVO — the industry-standard professional lighting simulation software — to design and document lighting plans for residential renovations and commercial projects.
DIALUX Lighting Design
Professional lighting simulation and planning for residential remodels, commercial spaces, warehouses, retail, and offices.
✓Homeowners remodeling kitchens, home offices, or garages
✓Retail stores needing proper display lighting (500–1000 lux on merchandise)
✓Offices requiring ergonomic task lighting (300–500 lux at desk level)
✓Warehouses and industrial facilities meeting OSHA 1926.56 standards
✓Restaurants and hospitality venues creating ambiance lighting zones
✓Architects and contractors needing lighting sign-off documentation
DIALUX EVO is used by lighting engineers and architects worldwide to simulate real-world lighting conditions before installation. The software calculates exact lux levels, uniformity ratios, energy consumption (W/m²), and glare values — ensuring your design meets IES and IESNA standards.

If your lights flicker, buzz, or won’t dim to low levels, your dimmer is likely not LED-compatible. Most pre-2015 dimmers were designed for incandescent bulbs only. We can replace your existing dimmer with a properly rated LED or smart dimmer — ask us about options for your specific fixture and bulb type.
Smart lighting gives you remote control via app, voice control through Alexa or Google Home, scheduling, energy monitoring, and AI-assisted automation. In 2026, smart systems also integrate with Colorado utility platforms for real-time energy feedback, and many qualify for Xcel Energy rebates.
