"Badly. 2 different techs came out. We paid for a Premium service and within hours of that tech coming out, our burner stopped working completely. Mind you there is a snowstorm. They sent out a new technician and he saw nothing wrong with the system at all. He said we had no oil. He said there was no footprints even going to my intake on the side of my house. It had snowed 2 times since oil was delivered, so that makes no sense. The tech was absolutely sure we had no oil. 3 days since the first visit now and we had oil delivered and the tank filled completely. Only 150 gallons went into my 250 gallon tank. So that's wrong. And I look at the front of my furnace and now see a slow drip from the front underneath the box on the front of the furnace. First tech recommended i replace the electrodes but said it didnt need it. Second tech didnt even mention that and said our system was good. Now, I will have to contact Angi for support and my insurance company. TERRIBLE TERRIBLE TERRIBLE"

"Signed contract on May 8 for deck build.On May 12 rep came to my office to collect deposit of apprx $13,000. He said project team meeting on Wed & would update me then on start date etc. On Fri May 16 I had to reach out to him. He wrote the team had met & materials were ordered. An hour later he wrote back that he was misinformed & that his boss was going to call me next week. Despite this, dep check cashed. On Mon 5. 20 rep wrote back that they had forgotten certain costs & to proceed it would be $8,000 more. Not a typo. $8,000 more. No apology. Ridiculous, contract rescinded. I wrote that he could return my deposit at my office just as he had collected it. On Wednesday the 21st I got a text from "Tom," presumably the owner/boss, saying he would "drop a check in the mail" to my address. Today is May 30th, Friday, and still no check. Check at a minimum should have been overnighted. They owe me interest not to mention the deposit to hire a contractor who will honor contract. Bad."

"This was one of the worst remodeling experiences I?ve ever had. I was completely oversold on what they could deliver. I hired them for a bathroom remodel and was promised a spa-like retreat. What I got instead looked like a cheap hotel bathroom. The price was outrageous. They pitched me at around $38,000, and I agreed because I thought I was getting a high-end, premium product. That was absolutely not the case. The materials and design options were extremely limited. They only work with one brand, and they push it aggressively like a bad timeshare presentation. To make matters worse, the price didn?t even include the vanity or any accessories. I had to provide all of that myself. For nearly forty grand, that is completely unacceptable. The workmanship was okay, not great. They were in and out in a day, which was convenient, but it clearly came at the cost of quality. There are spots where the work looks rushed and careless. This is a $15,000 bathroom at most."

Fire Sprinkler Companies questions, answered by experts

Each sprinkler zone should have five to 10 sprinkler heads. The water source for sprinkler systems has an average of 30 to 50 PSI and 5 to 8 GPM. On the lower end of these ranges, you’ll need fewer sprinkler heads per zone. The number of sprinkler heads per zone you need ultimately depends on the size of the zone, the water pressure, and the flow rate.

Services include running cables, installing outlets, configuring hardware, and testing the network.

The color code for the common sprinkler wire is white, and then you can assign the remaining color codes to the rest of the wires for different sprinkler zones. For example, you could use red for the first zone, then blue for the second, and so on.

Color-coding helps you keep track of which wires go to specific zones so that you or a pro can address any issues or repairs quickly. Check your local electrical code for any requirements regarding sprinkler wire colors.

You can expect your water bill to increase when you use your sprinkler systems, but how much it will increase depends on your water company. To keep water bills as low as possible, only use your sprinkler system when you need to, particularly during hot summer months when there hasn’t been much rain. Keep an eye on your bill, so you have an idea of how much it goes up because excessive jumps in your bill amount could be a sign of a leak in your sprinkler system or elsewhere in your home.

Daily for the first two weeks, then gradually tapering as roots establish.
