We offer turnkey solutions for both residential and commercial customers — no job is too large or complex for our expert team.
"Absolute ripoff, along with shady business practices. They were prompt and courteous, but that's about it. The technician came and had to replace a $200 part on my boiler, it took him under an hour to do the work. A simple Google search showed at least 10 places to buy the exact part, all around $200. No other parts were needed for this repair, I researched what is involved. I was charged almost $1000, including their $89 diagnostic fee just to walk in the door. So apparently it's a $600+/hour labor rate? I'm obviously in the wrong line of work. This was not an off hours emergency call either, it was a scheduled appointment in the middle of a weekday. The shadiest part of the entire thing was that on the invoice (that they email you later) they bury all the cost, it's not itemized i.e. labor vs parts cost. It just says replaced (part) = $1000. A super scummy and shady way to run a "professional" business, taking advantage of people who don't know any better. I wouldn't be surprised if they also sell used cars. Never again Gervais. You've all been warned."

"We had an issue with a Dry Well periodically backing up. Damian and the D Day Plumbing team were very professional and knowledgeable and provided an estimate with a couple different options and their related costs. They installed a new utility sink, sink pump, and needed piping and valves with tie ins to the main septic. They made improvement above and beyond the initial job breakdown, all the while staying within budget. I will certainly consider them again for any future work. Thank you Damian and the D Day Plumbing Team for a job very done!"

"Very prompt, knowledgeable, and professional individual. Shawn was the most thorough of all potential contractors in reviewing my replacement boiler situation, and was able to convince me that I did not need a larger boiler recommended by another contractor. He arrived and completed the job as scheduled, and his work was excellent. The piping is neatly arranged and marked should I need to isolate a heating zone, and he took the time to explain all fluid flows for the heating system. I could not be happier with using Shawn for the installation of a replacement oil burner and hot water tank."

"Young man who came to do the job told us that they sent him to 3 wrong houses before they found ours. He proceeded to unclog the drain in the basement using the mechanical drain. Took him maybe an hour to clear it and also ran our sinks and toilets to make sure we wouldn?t have another problem. The young man left our house, however proceeded to sit in his running van, parked in my parking spot. I had no issues with this service until I saw the bill. $1000 to snake a drain for an hour? When we inquired about the bill they told us that their rate is 300$ an hour and that the job took 3 hours. In my opinion, if it takes you 3 hours to snake a drain, then someone should be fired or retrained at their job. My assumption is that their scheme involved sending this young man to multiple wrong houses and him sitting in my driveway for a prolong period of time, so that they could charge us for 3 hours of ?work.?

FAQs for heating oil service projects in Leominster, MA
To buy heating oil for your house, contact local heating oil companies to compare prices and place an order once you decide on a supplier. The company will have to deliver your heating oil in a truck designed to carry and dispense heating oil safely. Call and order your heating oil early enough to have your oil delivered before you need to start using it for home heating.
On average, you’ll need about two gallons of oil per day to heat your house when it’s 50 degrees Fahrenheit outside. Most oil tank capacity is about 275 gallons, and heating your house with two gallons of oil per day will last about four and a half months. This consumption will vary depending on the climate and average temperature in your location. For example, if the winters are longer and colder where you live, you’ll probably need to refill your oil tank at least once to get through the winter.
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.
Summer months tend to be when heating oil prices are lowest because of decreased demand. Buying heating oil during the off-season also prepares you for when the weather gets cold, and you need to start using the oil to heat your home. Although heating oil prices will fluctuate, it’s best to avoid purchasing between September and April, as that's the peak season for heating oil demand.
Overall, heating your home with an oil furnace tends to be less expensive than heating your home with an electric heating system. Oil heating systems stay warm for longer periods of time without drawing a constant electrical current to maintain a temperature. Plus, heating oil systems typically have a longer lifespan and lower price tag than their electrical counterparts, resulting in short- and long-term savings.
