As the trusted neighborhood HVAC service team in Milwaukee, Mr. Holland’s Home Services is committed to running their business based on five important principles: care, empathy, and trust, being always available, outworking the competition, quality workmanship, and using their “find a way” method. By keeping these five principles in mind, the business is able to deliver nothing less than excellent work when it comes to heating, air conditioning, and indoor air quality services. The professional team at Mr. Holland’s Home Services always gets the job done right. They never cut corners and are respectful of a customer’s property. Additionally, Mr. Holland’s takes their community involvement seriously; that they have a personal responsibility to help the people in their community, not just through quality services but also through the endless support they give to organizations and charities throughout Milwaukee and even outside the country. To learn more about Mr. Holland’s Home Services, please visit the company website or call the office today.

"On September 11, 2025, I hired Mr. Holland’s to clear and diagnose a main line clog. I was charged $738.04 for drain cleaning with a snake. The invoice states the technician attempted to snake the line multiple times but could not get it open, and because the drain was still impacted they were unable to camera the line. I was told the blockage was around 90 feet from the access point, but my own measurements showed that distance would place the problem across the street, which did not make sense. In reality, the blockage was never cleared and the scope I paid for was never attempted. Even though the line was still blocked and never scoped, I was given a written estimate for $39,900.34 to excavate and replace about 7 feet of my sewer lateral. That estimate included removing two sections of sidewalk, excavating down 9 feet, cutting out and replacing pipe with PVC and a cleanout, slurry backfill, and sidewalk replacement — but no landscaping restoration. No spot-repair options were offered. I later hired Subterranean Sewer Experts, who scoped the line and found the actual blockage about 30 feet inside the basement, not 90 feet away. They also scoped another access point closer to the street, which confirmed the sewer lateral was clear and did not need replacement. I had paid Mr. Holland for clearing a clog and performing a scope, neither of which were done. I was told by both phone and text that my payment would be refunded; I even saw the refund pending, but it was later reversed without notice. Because the blockage was left in place and the scope was never done, I was forced to hire another company and pay an additional $747.40 to complete the work Mr. Holland’s failed to perform. Based on my experience, I was charged for a service that was not performed, left with a blockage still in place, given a nearly $40,000 estimate for unnecessary sewer work, and denied a refund that was promised."

FAQs for electrical wiring or panel upgrade projects in Grafton, WI

Electrical wiring can last between 50 and 70 years if properly installed and maintained. However, factors like moisture damage and overloading outlets can shorten this lifespan. To extend your wiring's life, unplug electronics when not in use, avoid overloading outlets, and schedule regular electrical inspections every five to ten years.

If your house was built in the 1960s and hasn't been rewired, it likely needs it. Older homes may have outdated wiring like knob-and-tube, which poses fire risks due to flammable insulation. Rewiring ensures safety and may also require updating your circuit panel, outlets, switches, and fixtures. Contact a local electrician to help with your rewiring needs.

Yes, rewiring your house is worth it, especially if your wiring is outdated. It improves safety by reducing fire risks and can increase your property's value. However, you may not need a full rewire. A home inspector can tell you if a partial rewire will bring your home up to code.

Yes, you can sometimes rewire a house without removing walls. Electricians might access wiring through attics, basements, or crawl spaces, or make small holes to run new wires. However, this isn't always possible, and in some cases, removing sections of walls is necessary to ensure the wiring is installed safely and meets code.

A house should typically be rewired every 25 years to maintain safety. Over time, wiring deteriorates, increasing fire risks. Regular electrical inspections every five to ten years help assess the need for rewiring. Staying proactive with maintenance ensures a safe, efficient electrical system and prevents potential hazards before they become serious issues.
