"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

It’s usually better to repair your generator if it isn’t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around $300 on average, while installing a new whole-house generator costs around $5,000 on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.

Yes, in most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home models. Because these installations involve significant alterations to your home's electrical system and produce exhaust fumes, local governments often require a permit or inspection for safety purposes. A generator permit typically costs between $50 and $250, depending on your location. Your electrician or certified installer can usually handle the permitting process for you, but you will be responsible for the cost. It's a good practice to confirm with your installer that they will pull all necessary permits before work begins.

Costs range from $500 to $2,500, depending on generator type and installation complexity.

It might seem counterintuitive, but installing a generator transfer switch will save you money in the long run. While you’ll have to pay between $400 and $2,500 to have the transfer switch installed, you’ll recoup that amount later on when you don’t have to pay for expensive repairs to your appliances, devices, and electrical system that may have burned out, overloaded, or stopped working due to a sudden loss of power or an incorrect hook up of a generator to your home. 

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.
