"Fast and super helpful. Gave me a proposal right away. Started work same week. If deviations were needed, was specific on what and why. Reasonable and fair pricing, and honest about their capabilities and areas of expertise. Professional team and went out the way to provide additional references for other concerns. I also appreciated the video Fabio took to show me the before and after, especially in areas I was unable to see."

"I hired M&B Electrical and Mechanical Solutions Corp. for an electrical wiring/panel upgrade, and I?m genuinely impressed with the entire experience. From the first conversation, they were clear, patient, and willing to explain everything in a way that made me feel confident about the work that needed to be done. The team showed up on time and got straight to work. They were very respectful of my home, kept the work area organized, and took the time to walk me through what they were doing as the project progressed. You can tell they take pride in doing things the right way; nothing felt rushed or halfway done. The panel upgrade was completed smoothly, and they made sure every connection was safe, clean, and up to code. They also tested everything before leaving and answered all my questions without making me feel rushed. It?s rare to find contractors who combine technical skill with really good customer service, but they definitely do. Overall, I?m extremely satisfied."

Customers say: Quality work

"Artique Constructions did an amazing job with my bathroom and kitchen remodeling. Can not recommend enough for their quality of work and commitment to deliver to perfection. I chose very modern high end designs and their work was impeccable. I would have spent more than double if I had gone for anyone else. I got complete remodeling of kitchen(floor/cabinets/island/pantry/installation of all kitchen appliances/backsplash/open shelves/led ceiling lights) bathroom(bathtub/vanity/floor/bath tiles/built-in shelves/toilet), changed all switches and electric boxes, trims throughout the house, paint, door knobs, hinges, custom wall paneling. Garry made the house look like a million bucks houses featured in magazine. He is very trustworthy and patient. His attention to detail is amazing. Would suggest anyone who wants to get their house in amazing shape with no hidden costs Garry is the person to go to."

"Couldn't recommend more highly! I left my stormdoor slightly ajar during a windstorm and it was almost ripped off the hinges. Danian responded quickly, provided an estimate and had a new door sourced and installed in no time (he even came out after hours to deliver the door and took time and care to install it, despite the freezing weather, on a weekend). The cost was exactly as quoted and extremely reasonable, particularly given the quality of the work."

Generator Install questions, answered by experts

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

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

While the rating will tell you how many watts the refrigerator needs at the peak of its cycle, it requires additional wattage to start. At the bare minimum, you’ll need a 1,500-watt generator to get the fridge up and running after a blackout. A 2,000-watt generator should be sufficient for most home refrigerators.

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.
