We service all brands of portable and stand by generators. Work before 6 am as well as night after 6pm, weekends and holidays is subject to additional charges. We normally charge $125 to clean dryer vents and that's it. We provide outstanding, well equipped mechanics, who know their jobs. YOU GET WHAT YOU PAY FOR- TOP SHELF FIVE START SERVICE.

"The experience was not quite what I expected. I had clearly explained the scope—replacing 10-12 standard switches with smart switches giving model number/spec—and was hoping for a lump sum proposal, but they only offered hourly rates, which is understandable. They estimated it would take about 2 hours, but the job ended up taking over 4. While they mentioned having done similar installations before, they spent quite a bit of time reviewing instructions on site, which added to the time and cost. The final bill was over $800 for a couple switches, including a service fee and $10 for wire connector? (The switches come with connector) Just a heads-up to others: be sure to ask detailed questions about hourly charges and how time will be managed, especially for smart device installations."

"If I could, I would give this horrible service provider a 0.0! I scheduled a plumbing appointment on a call, which was confirmed via multiple texts the day prior to the appt. Then had an employee go to the location during the 4 hour window they specified and wait for the plumber. On the day of the appt, 1 hour into the time window someone calls and says, sorry we’re not going to go because we only do residential plumbing. This was a surprise, as it was communicated to them that this was a business when I had set up the appt. So, I decided to speak with a manager. After spending over an hour of being bounced around from one dept to another, asking for a manager, they never connected me to one and their dispatcher had the audacity to say “sorry for your inconvenience, but you’ll just have to find someone else.” WOW! The hoops they make you jump through and the rudeness is not worth the hassle. I would definitely recommend you find a different plumbing pro for your project!"

"Contacted National Home Improvements regarding leaking patio roof and no follow up response to issue since last year of April 2023. Still awaiting to hear back. Seems like the rain gutter is sagging in the middle of the patio where the two joints meet and water is pooling there and possibly leaking through the seams as illustrated in the photo. Poor design concept. Really disappointed with customer service and quality of product especially for what we have paid for. They clearly don't care about taking care of their customers. I would never hire National Home Improvements again!!!"
