"I hired Beacon to install an attic fan and route the two exhaust vents from my restrooms outside. With the attic fan, I don't have any complaints. It seems to be working as intended. I cannot say the same for the restroom vents. The tech had to come to my home on three separate days to fix an issue. 1. He had attached the vent pipes in a Y design. Which ended up reducing the fan efficiency and it pushed the steam to the other restroom. It also caused the fan to drip water. 2. He added dampers. Which then blocked the steam from leaving completely. We had to use a dehumidifier to shower. 3. When I finally persuaded then to dedicate a line to each fan. I was charged an additional amount. Unfortunately, my fan STILL drips water. Meaning it was not installed correctly. So, I'm not sure what I as the customer can realistically do but to avoid them. Pictures attached show dripping and the one exhaust port for the two fans. Installed in the eave? Not sure this is code."

"Don’t use the plumbing! Called to have Kohler toilet tank plunger repaired. Whole installation is $20. Labor is an hour at $80 so the price is $150, at most. No, they charged $450–BS! These guys are a scam. No prices and I told them to have the repair person call me before arriving. No call, no prices. And, then the repair person has the stones to tell me that everyone overcharges!! Let’s start with not using Beacon!!!"

FAQs for electrical wiring or panel upgrade projects in Kensington, MD

Electrical wiring can last between 50 and 70 years if properly installed and maintained. However, factors like moisture damage and overloading outlets can shorten this lifespan. To extend your wiring's life, unplug electronics when not in use, avoid overloading outlets, and schedule regular electrical inspections every five to ten years.

If your house was built in the 1960s and hasn't been rewired, it likely needs it. Older homes may have outdated wiring like knob-and-tube, which poses fire risks due to flammable insulation. Rewiring ensures safety and may also require updating your circuit panel, outlets, switches, and fixtures. Contact a local electrician to help with your rewiring needs.

Yes, rewiring your house is worth it, especially if your wiring is outdated. It improves safety by reducing fire risks and can increase your property's value. However, you may not need a full rewire. A home inspector can tell you if a partial rewire will bring your home up to code.

Yes, you can sometimes rewire a house without removing walls. Electricians might access wiring through attics, basements, or crawl spaces, or make small holes to run new wires. However, this isn't always possible, and in some cases, removing sections of walls is necessary to ensure the wiring is installed safely and meets code.

A house should typically be rewired every 25 years to maintain safety. Over time, wiring deteriorates, increasing fire risks. Regular electrical inspections every five to ten years help assess the need for rewiring. Staying proactive with maintenance ensures a safe, efficient electrical system and prevents potential hazards before they become serious issues.
