"I hired Eastside construction To Tape and texture 2 Hallways and a master bedroom, closet and bath. The taper Tom was personable but was the Sloppiest Taper I have ever been around. I have been in the trades since 1972. i requested that Tom scrape out the corners before shooting the texture at least three times, this was done half heartedly. I mentioned to Tom he was the sloppiest taper I had ever seen and asked who was going to clean up his mess. He replied Dean usually sends a crew around, but that was between me and Dean. There was no cleanup crew supplied by Dean. there are several areas that were not sanded properly and texture was shot anyway. I only saw these areas while I was painting. I would never hire this company again. The mess Tom Made and tracked through our house was inexcusable. My wife and I covered our floors, taped off the outlets, installed zipper doors to help keep the dust down. Tom belongs on a Commercial jobsite not an occupied home. I won't make this mistake again.

"Martin did excellent with communication and keeping me informed about what needed to be done. He answers his phone or calls back quickly. He came out to assess the job quickly and started within a short amount of time. He shopped for all supplies needed and showed up ready to work. He completed the job within the time frame he said he would. As a woman I was very comfortable with him and his great personality and knowledge of the field. I would highly recommend him for any work you need large or small."

FAQs for thermostat installation and replacement projects in Seattle, WA

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.
