We needed to repair a dripping pipe behind the p-trap in our bathroom. We have a 1928 bungalow and the pipe coming out of the wall had lost the threading on it. The plumber was very helpful in replacing a small pipe that went into the wall. He was thoughtful and only cut a very small hole in...

I returned from a business trip to find my laundry room flooded. I found Arrow on Angie's List and gave them a call. They managed to work me in the same day, even agreeing to call me 20 minutes before the repairman arrived so I could run home from the office and meet him there. The repairman...

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."

"Technician Jim was not impressive. Was not confident when answering the questions I asked. Very contradicting.. Tried to sell product for items that were not even in need of repair. Spoke negatively about the company and made excuses as to why he could not perform his job due to lack of information from dispatch or technician manager. Said he would follow up, I never heard from him. Blessing to me, I decided to go with another HVAC company. I typically would not put names out there, but please be careful if you get this gentleman as a technician."

FAQs for boiler repair projects in Slinger, WI
The average cost to install a new water heater is around $1,300, but you can expect to pay between $875 and $1,750, depending on the kind of water heater, the size of the unit, and the professional chosen to complete the work. Tankless water heaters can push your price higher, as installation is more complicated, with prices as high as $3,500. The location and accessibility of your water heater will play a role in the project cost, as those sitting in tight spaces like a crawl space will drive up your labor costs.

It is very difficult and dangerous to install your own water heater, so we strongly recommend against tackling this as a DIY project. Not only will you need to wire your water heater, but you’ll also need to connect plumbing to the intake and outlet. Sweating copper pipes and connecting wiring properly are skills most DIYers don’t have, and even if you do feel confident you can do it, working with water and electricity always leaves the potential for electrocution. Hiring a local water heater installer is well worth the investment.
The average cost to hire a plumber is around $100 an hour but can vary between $45 and $200 an hour depending on the plumber’s experience and the repair that you need. It’s also important to note that these prices can go up on holidays, and emergency plumber rates average $150 per hour, in addition to a flat-rate trip fee of $100 to $350.
