"I hired K & K to install a range hood. There was no electrical there previously so they had to run electric. I also had them install a new light fixture and remove an exhaust fan. K & K did excellent work and even repaired an electrical box that another contractor had installed. I was given a great estimate and was charged the estimate price. Would definitely use again and recommend."

"Russell was prompt, very polite and helpful. He explained everything and pointed out where my old rowhouse differs from newer codes. (Grandfathered until I want to sell.) There was an upsell on an annual plan, but it will save some 15% on some planned upgrades, so I went with it. Dawn, office support, also was friendly and pleasant to work with. She gave me a follow-up call next morning after my multi-company query through Angie's. My inquiry detailed list of three small repairs did not get other takers, so no real cost comparison, but I feel the price was fair-- $500 for about 2 hours, including the plan and dispatch fee."

"Things went well. Russ Piper came out and met with me - to see what the project entailed. Meeting went well, I fully understood what they were going to do. I got a quote back quickly and moved forward with it.   When the plumber (Plumb Crazy)came out to see what needed to be done, I had some options .  I decided to have a higher service line brought into the home - now BGE is involved.   Without further stories - it took many weeks to get BGE to install the higher service, Throughout, this process, Benfield and the plumber where checking in with me for progress.  And when the inspections where all complete - they came right out and finished the installation."

Generator Install questions, answered by experts

With proper maintenance, a whole-house generator can last between 20 and 40 years. The specific lifespan depends on how often and for how long the generator is used, and some models may have their life expectancy rated in hours of operation. To maximize its lifespan, expect to spend around $150 to $300 per year for annual maintenance checks from a qualified technician. During these checks, a technician will inspect the engine filter, starting mechanism, fuel, lubrication, and coolant levels. Consulting your installer and choosing a low-impact fuel like natural gas or diesel can also help ensure your generator lasts as long as possible.

Yes, installing a generator usually increases your property value because buyers are getting the added peace of mind knowing they’ll be able to maintain power through blackouts. In most cases, you should see close to a 100% return on investment (ROI). Keep in mind that home generators usually need a permanent foundation, and installing a concrete slab will likely raise your property taxes slightly.

Portable generators provide backup power for essential appliances during outages and are easy to relocate.

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.

Natural gas generators are designed to run for extended periods of time, such as power outages during a natural disaster. Since there’s no limit to the supply of natural gas, they don’t need to stop for refills. However, generators do need maintenance, including pauses to check and add oil. Constantly running them will also cause a lot more wear and tear, leading to a shorter lifespan.
