- Closely follow the average True Cost Rate furnished on the Homeowners section of Home Advisor for labor costs - Show up on time and give up front estimates - Focus on service work and limited multi-day projects so my schedule remains fluid - Advocate on the customer's behalf shopping for best prices on quality materials and best practices to get jobs done to code at the best rate possible

"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!"

Doug Anderson Plumbing & Heating was built from the ground up with hard work, dedication, and a genuine passion for helping people. Doug began his plumbing career in 2009, starting as an apprentice and learning the trade the old-fashioned way?through long days, hands-on experience, and a drive to always do the job right. By 2016, he had earned his master plumber license and was ready to take the next step: starting a business rooted in quality work and honest service. In 2017, Doug Anderson Plumbing & Heating officially opened its doors. As demand grew, Doug?s wife stepped in to help run and organize the operations, bringing structure, support, and leadership to match the technical expertise in the field. Together, they?ve grown the company into a trusted, family-run business known for reliable service, skilled craftsmanship, and a deep commitment to the people and homes they serve.

"I needed 2 backflow preventers replaced , a water heater repaired and a to0ilet repaired. I had a quote from a very famous local plumbing/heating company for $4000! I called Doug for a second opinion and he came in at HALF the price!! and that was AFTER I showed him the first quote! He didn't seem surprised at all about the first quote. Not only was he half the price but he pointed out that my 6 year warranty on my water heater had 6 months left and said I could get a new one thru that warranty for $100!!! He took care of going thru the company getting me the new heater. He completed the job in a few hours. I will NEVER call another plumber again! My recommendation is to run, not walk, to get Doug for your needs. On top of that he is so very nice. I would give 10 stars if I could."
