- 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!"

"The provider came out to prepare my toilet because it was leaking in the basement. Overall, I thought the process went well. He could not get the valve beside the toilet to turn off so he turned off my main water valve to the house. He only opened up the faucet upstairs unit Downstairs unit was not open and my water heater, which is electric was not turned off now I m getting an alarm on my water heater saying it has been compromise. I consulted a plumber and was told that the water heater should ve been turned off because it s electric and he should ve bled the water heater After he turned the water back on. So the alarm is still on my water heater."

FAQs for thermostat installation and replacement projects in Littleton, MA

Smart thermostats may be worth it for many homeowners. They come with various features, including voice control and smartphone apps. Vacation mode can help lower energy usage when you’re out of town for an extended period. Alert warnings let you know about major spikes or drops in temperature. Smartphone apps can track energy usage, and smart thermostats can learn your routine over time to adjust your temperature and reduce wasted energy consumption automatically.

You typically do not need more than one smart thermostat. While it’s common to see multiple mechanical thermostats throughout a large home, multiple smart thermostats may try to override each other. This can lead to problems with the HVAC system. Ensure the unit you buy has the option for dual- or multi-zoned systems to avoid compatibility issues.

Installing a programmable or smart thermostat may save you $180 per year in utility costs. A big part of this comes from a smart thermostat’s ability to learn and adapt to your regular routines. With smartphone apps or web-based interfaces, you also have the option to control your thermostat when you’re not home.
