We know it’s tough to find a home services contractor you can trust. With over six decades of experience, Blanton’s is a Raleigh and Fayetteville mainstay. Known for our professional approach, quality products. and guaranteed workmanship, we’re proud to offer heating, cooling, plumbing and electric solutions that knock your socks off.

"Cancelled all services with Blanton as well as this well pitched Wow Service Plan. Was given a good pitch about services provided. However, after scheduling twice for services provided by service plan, only to have them cancelled and told need to reschedule. Today is was need to reschedule because they are anticipating (four days from now) a high volume of emergency calls due to cold weather and freezing temperatures. What cold weather? 52 and 43 at night are not freezing temps; 69 and 67 daytime are not freezing temps. So you reschedule appointments four days in advance with no actual justification or confirmation the day of of what you think might happen? Sounds more like laziness or a reason not to fulfill appointments made almost two weeks prior. Second, why have an online system that allows you to book an appointment and date but when you call to complete the appointment process, tell us that the dates that show on the calendar as “available” don’t actually mean they are available? The lady I spoke to said they are run by two different departments. Sounds like you need to update your systems and booking process that actually shows dates of availability so customers don’t waste time picking a date that isn’t actually available and waste time. Or get rid of calendar option altogether so you cannot select a date that isn’t in “real” time."

"Matt did a great job installing my first ceiling light/fan. He identified that the second ceiling light/fan required a different box in the ceiling, and ordered the correct equipment. Rob came a week later and did an awesome job installing the second ceiling light/fan. His attention to detail was remarkable! Great job Matt and Rob!"

We are one of the few plumbing companies with a full one year on all parts and labor guarantee. That alone tells you your plumbing troubles are over.

"The plumber reworked the drain piping under the sink in December due to a leak at a connection joint. 3 Months later a connector came loose while the dishwasher was running and water flooded the sink cabinet. I called Dr Drain and was informed it would be 4 days before someone could come out and fix it. I explained this was an emergency, the kitchen sink was inoperable due to the drain pipe being disconnected and I could not go 4 days without my kitchen sink. The person I spoke to did not say they were sorry this happened (it was obviously not hooked up correctly in the beginning) or offer any help in the situation. It is unexceptable for a plumber to not offer emergency services when something they did failed and made the sink inoperable for 4 days."

"It went very well. Took a bit longer than expected. Only because someone took his puller, but he pushed through and got it done. What was really nice is that even though a mix up occurred and the unit didn't get registered after it was installed as this was new construction with a custom builder. Dolan honored their 10 year contract."

Boiler Repair questions, answered by experts

To figure out if your boiler is worth repairing or if you need to replace your boiler, first figure out how old the unit is. Boilers last 15 to 20 years, so if your unit is 15 years old or older, it may be better to replace the entire thing depending on the severity of the problems. If it’s not quite that old, then it’s probably worth repairing. Another thing to consider is whether your warranty covers any of the repair costs. If so, it may be worthwhile to repair your boiler to keep it running.

You save money on heating oil in a few ways:

  • Make sure your home is well insulated and sealed against drafts and heat leakage.

  • Use a thermostat that’s working properly and calibrated accurately.

  • Increase energy efficiency by insulating your basement and attic.

  • Turn down your thermostat a few degrees.

  • Program your thermostat to lower the heat when you’re not home.

  • Order heating oil during the off-season when prices are likely to be lower.

It takes about five to 10 minutes for heat to reach a radiator, then about one hour until the radiator fully heats up a room. The exact duration depends on the size of the room and how far away the radiator is from the boiler heating system. Heating up an entire house could take up to two hours.

Boiler leaks are the most common problem that impacts this fixture. Some leaks stem from corroded pipes and tanks, while others are due to damaged seals or excessive pressure. No matter how you slice it, boiler leaks are bad news. This issue leads to water damage in the home and malfunctioning electrical components in and around the boiler.

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.
