Everlast did a great job replacing a sliding patio door for me. Install looks great, they sealed the new door in well, and even cleaned up the broken glass from previous door. They charge a fair price for their work and communicate well.

We had a dryer vent relocated in our home. We had a slight misunderstanding about how to run it, but in the end the job was exactly what we wanted. The installers were polite and courteous the entire time and completed the job when they said they would.

I originally called to get my dishwasher door adjusted from sticking. But then thought to ask, while scheduling, (it was not last minute requests), about my washer spinning off / out of kilter and the dryer hose needing to be replaced. He did all of that and was done in less than an hour....

Dishwasher Installation questions, answered by experts

Yes, a dishwasher needs an air gap to prevent backflow. Additionally, in many locations, air gaps or another measure to prevent backflow are required for building code compliance. There are alternatives to an air gap, like a Studor vent or a loop and trap design, but an air gap is the simplest and most popular solution.

Most dishwashers are designed with a standardized width of around 24 inches and can fit into most kitchen spaces intended for dishwashers. However, the height and depth might vary slightly, requiring careful measurements to ensure a proper fit. Certain specialized or compact dishwasher models might deviate from the standard size to accommodate specific needs or non-standard spaces. While many dishwashers adhere to a typical size, measuring the available space accurately is crucial to guarantee a seamless installation.

Yes, vinegar is an excellent homemade solution to clean a dishwasher. Its acidity will cut through any buildup, while its natural deodorizing capabilities will take care of any nasty smells.

Installing a dishwasher should take one to four hours, depending on the complexity of the installation and whether you DIY or hire a pro. Even if you're particularly handy, installing a dishwasher on your own will likely take longer — at least two hours. On the other hand, a professional can likely install a dishwasher in about an hour. Installation time will take longer if you have to remove an existing dishwasher, reroute plumbing, or repair damaged flooring underneath the appliance.

It’s not worth fixing a 20-year-old dishwasher or any 20-year-old appliance. Twenty years is beyond the useful life span of nearly every major household appliance. Once the appliance nears the end of its useful life span, repairs will become more frequent. A replacement often becomes more cost-effective at that point.
