- 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!"

"We had a great experience with Ryan Hamilton Electric when they came to work on our building and in our apartment. We had discovered that the knob and tube wiring that we thought had been removed from our apartment was still present, and so we hired Ryan to remove the old type of wiring and bring our unit up to code. Ryan and his assistant Tim went above and beyond when it came to doing the work. Ryan explained very clearly to us exactly what the issues were with the knob and tube wiring and showed us exactly what had to be done to fix the problem. We had no surprises. While we were hiring Ryan to remove the old wiring, we also asked him about doing some other electrical work in our apartment. Ryan was happy to add on these further improvements and charge us only for the materials since we were already paying for the labor. Ryan listened to our desire for improved lighting and better outlets, and he presented solutions that would work for us and our kids. He found the perfect lighting fixtures for all the bedrooms and the bathroom, and he offered to improve lighting when it seemed necessary. The project took a few days; Ryan made sure we had the temporary lighting we would need in the evenings after he had completed work for the day. Ryan and Tim also cleaned up beautifully each afternoon when they were done with their work. Ryan and Tim didn't just do exemplary work. They were also warm, friendly, and affable, and a delight to have working in our apartment. We will actually miss having them around, but we were so impressed and delighted by their work that we plan to hire them again soon to improve the lighting in the kitchen and to install new outlets in the bedrooms. R. A. Hamilton Electric has my highest recommendation. I am a very happy and satisfied homeowner."

" The sales representative I spoke with, misrepresented the services in order to secure a service call. She told me the truck would arrive fully equipped to handle diagnostics, battery work, and related issues to fully diagnose a generator, which turned out not to be true. The technicians who came out were polite and professional, and this review is not directed at them in any way.. This ended up wasting a significant amount of my time and money"

We offer a 10% labor discount for new customers, plus for senior citizens and military veterans at all times. Although our work schedule is Monday thru Friday 7:00am to 3:00pm, we offer 24hr emergency service and free estimates at any time. Our quotes are locked in prices, but if we complete the work in less time, the cost of the work becomes less.

"We had mold that another company removed. Todd and Dave at Booth Home repair were very professional during the estimate phase and pointed out a few areas the other three contractors did not see. They were punctual, friendly and had a reasonable quote. They started when they said they would, and treated our house as if it were their own. We are more than pleased with their finished work and would recommend them highly."

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.
