At Toolbox Dispatch, we understand the importance of a well-maintained home or workplace, and we are here to ensure that every project, big or small, is completed to your utmost satisfaction. Whether it’s a repair, installation, minor renovation, or general maintenance task, you can trust our experienced team to handle it with expertise and efficiency.

"The refurbishing of a master bathroom has been a nightmare. The project was rather simple: remove and replace fiberglass shower/tub enclosure, remove sheetrock and re-install new sheetrock, remove existing vanity sink and replace, install shower faucet and shower head, vanity faucet. They provided an estimate of 8 days to complete the job. It has taken many weeks and not even done adequately. It is so bad that I have to hire another contractor to pull out the shower walls and re-install new ones. They ruined it with their sloppy installation and not following instructions. When they apparently tried to fix it – it just looked worse and worse. Their plumbing sub-contractor made a big blunder and did not seal the pipe for the new tub faucet. This caused water to come through the ceiling onto the first floor and they had to replace a bunch of sheetrock in the kitchen. They removed all the towel bars in the bathroom for the new sheet rock but somehow managed to lose one…and came up with a BS story that there was only one in there. That didn’t fly so the story changed to that it had to be destroyed when the sheetrock was removed. Another BS story as we were in the house when this happened and would have seen it being carried out. The mudding of the bathroom was sloppy, see photo of the light switch. The caulking is even worse – much of it is missing or just very poorly applied. That all had to be removed and re-done. There are too many other issues to list but we’ll be spending another $4,400 to fix the mess they left. I urge you to learn from our encounter and avoid them – it was NOT a professional job, the staff were mostly untruthful and often rude."

"Our realtor recommended Para home services when we bought our house, so we tried them out. Our team, Zoe and Matt were great, they listened to all my ramblings and half baked suspicions about what things were wrong with the house and set to work. On top of a thorough maintenance pass -cleaning dryer vents and refrigerator compressors, they also addressed a random list of things like a loose sink, and faulty bath faucet, a couple of dead outlets and misbehaving light switches but also troublshot our mysterious radiant floor system, got it all working and explained how it was set up. I learnt a lot about the house and ultimately have a greater peace of mind. I will be signing up for a membership."

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.
