"Beware of Brian Hoffman, DBA “Premier Services”. I agree with all the negative reviews here - I had the same experience. He did a bathroom project for me October ‘24. He did a poor job, including an improperly installed toilet that was leaking under the floor. He agreed by text message to a $300 refund in Nov. ’24, but still hasn’t paid as of the end of July ’25, even after losing in Small Claims Court. He uses multiple addresses in various LI towns and won’t tell you his actual current address. The one listed on Angi is a street that does not even exist. Now he won’t respond to texts or phone calls."

"RUN FAR AWAY FROM ALLIED AND TOM. Tom took my money and did not complete the renovations as per our contract. He lied about having a licensed electrician to do electrical work, it was just one of his workers who's not licensed. I paid for a dumpster and when it was delivered by tom it was already half full from another allied job and I was asked to pay the full amount of $950. Tom didn't listen to anything I said regarding the work I requested and he changed my design and did work that was cheaper for him. I was priced for one of my ceiling's to be ripped out and reinstalled with new sheetrock, Tom waited until I was away on business then he installed sheetrock on top of the bad sheetrock and told me he ripped out the old sheetrock and installed the new sheetrock, I found out when my EC cut holes to install lights and we found 2 layers of sheetrock preventing the lights from being able to be installed. Allied construction is a cheap, sneaky company who will steal your money and breach your contract. Do not hire these people Tom is a lair. Tom wore a gun in my house on his hip and told me "I use this to get paid by customer who don't want to pay". Tom left live 120v wires hanging out of the walls and ceiling, he removed a banister and didn't replace it for 3 weeks making my home very unsafe for me and my 9 year old son."

Plumbing Heating Companies questions, answered by experts

PEX pipes last up to 50 years on average, though they often last longer. This lifespan is comparable to that of galvanized steel, which ranges from 40 to 100 years. However, PEX piping is less likely to crack or break due to temperature changes. Due to that and the fact that it's easier to work with, many plumbers and DIYers are choosing PEX tubes over traditional metal piping.

Bleach isn’t likely to help unclog a sewer line. Bleach isn’t useful in this situation because it won’t dissolve the grime and debris in the clog. Instead, you want to use ingredients that will have a chemical reaction to clear out the buildup, like vinegar or salt and baking soda.

A burst pipe can cause hundreds or even thousands of dollars in damage. It could flood your home, which can destroy many of your belongings. It could also ruin hardwood floors and carpeting, requiring you to replace your flooring. Finally, mold and mildew form very quickly after high levels of moisture have been introduced to a space; this is not only costly to remove but also bad for your health.

A sewer cleanout typically looks like a white or gray PVC pipe with a removable cap. It's often located either in your yard or basement, depending on your home's plumbing configuration. The cleanout pipe is designed to provide easy access to your sewer system for maintenance and inspections. It may be flush with the ground or slightly elevated, making it distinguishable from other pipes. When you remove the cap, you can access the sewer line directly or determine its direction, which can be helpful when you need to locate your sewer line from your house to the street.

A bit of water in the bowl can help unclog a toilet, especially if you're using a plunger. However, if the bowl is full to the brim, you'll need to strap on gloves and remove some of the wastewater in a cup or container so it doesn't overflow when you try to unblock the pipe. If you're concerned about it filling further, manually close the flapper in the toilet tank or turn off the water supply to the toilet.
