Mark H on October 2025


"On 9/29/24, Justin from Noble came out to install a toilet flange riser. He looked at it and told me it would be between $450 and $550. I felt that was a very high price but a toilet is a necessity. It took him 2 hours from start to finish, but over an hour of that time, he was out buying parts at a Home Depot that is only 7 miles away. I was surprised that he didnâ t have parts with him considering this is a very common plumbing problem, plus I told them what I needed over the phone when I made the appointment and specifically said that I was telling them so he could show up with parts. When he said he was done, I looked at the toilet and noticed there were no caps on the bolts that hold it down. I asked if he was going to put some on, he said that most of the time he doesnâ t. He said he would put some on if I wanted, I told him I did. Who prefers the bolts showing on their toilet??? When he was done, he advised that the amount due was $490.00. I asked what their labor rate is, he said $250/hr. It seemed really high so I asked if it was because it was Saturday. He said â No, thatâ s our regular rateâ . So I was charged for two hours of which most of that time was spent on his trip to Home Depot 7 miles away. I paid him. As he processed the transaction on his phone, I asked if I would receive a detailed receipt. He assured me I would receive a detailed receipt in an email as soon as he finished creating it. It is now a day later and I have not received anything. Very disappointing. So in short: 1) So far the toilet is functional. 2) Justin was a pretty nice guy. 3) Price for the job was awfully high. I feel the job should have been 1/2 that amount because he should have had the necessary parts. I feel gouged. 4) The worst part is that I have not received a receipt for my $490.00!!"

Boiler Repair questions, answered by experts

Once you install your boiler, you can expect it to last for at least 10 to 15 years. Maximize the lifespan of your boiler by choosing a quality boiler, installing it properly, and having it professionally maintained each year. In the event that your boiler does need repair, address any issues immediately.

Blockages can occur for various reasons, primarily linked to the accumulation of debris or substances within the heating system. Common causes include the buildup of sediment, rust, or mineral deposits inside the boiler or its pipes, hindering water flow and heat transfer. Additionally, air pockets or trapped gasses can impede circulation. In central heating systems, sludge or corrosion within radiators can obstruct the flow of hot water. External factors like frozen pipes in winter can also lead to blockages. Regular maintenance will help prevent blockages and ensure efficient boiler operation.

To maintain a boiler and ensure it works optimally, regularly read the temperature and pressure gauges on the unit to ensure they're within the limits described in your owner's manual. Lubricate the circulating pump according to the manufacturer's instructions. Check the water level in the expansion tank and open the tank valve to drain it if it's more than half full.

If you don't clean a boiler, you may have higher energy bills or no heat. A dirty boiler is inefficient and can't properly maintain a heating system. It may break down more often due to corrosion or clogs from soot and oil buildup. Cleaning a boiler improves its performance. The cost to replace a boiler can be expensive, so keeping it clean is a cost-effective practice.

Even if you do everything right, your boiler’s pilot light might not come on. This has a number of possible causes, but the most common is a blocked jet. These jets are small and clog up even with a small amount of debris. You can clean it yourself or hire a pro to replace the component. Other possible causes include a faulty fan and frozen pipes, among others.
