"(1) 8 weeks into a 2-3 week completion plan (as stated on our paperwork), and our project still is not complete. Jan assured us before we signed the contract that *she has never in 25 years not finished a job on time*. Now she says the timetable was an estimate that only included demo and cabinet installation, and not even the granite, the sink installation, etc. One reason we went with them was the 2-3 week completion plan. (2) Jan did not start following up with us until we emailed her 7 weeks into the project saying they had one more week to complete it and then we would start deducting money from the balance due. Since then she has blamed the contractor, her office assistant, and now us. Totally unprofessional. (3) No one from her company was here when the granite people showed up before cabinets were completely installed, and gave us a hard time that the project was not ready for them. Jan also sent them a drawing with an island overhang, which we told her from the very beginning we did not want. (4) There was, and still is, a huge issue over a wine rack that was in the original itemized list, and now she is telling us is custom and takes 8-12 weeks to complete. (5) Our advice is to make sure every last item is in the contract and go over the spec sheet with a fine-tooth comb because Jan will refer to the signed contract with little regard for what she told you verbally. Better yet; do not use them, hire someone else."

Generator Install questions, answered by experts

If your home already has a grinder pump and you’re still noticing issues (like frequently clogged toilets and sinks), it could be time to upgrade your grinder pump. Start by checking your existing horsepower. If there are four or fewer people living in your home, using a 1/2-horsepower grinder pump should be sufficient. Larger households should consider investing in a 1-horsepower grinder pump to maximize wastewater removal efforts.

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.

When choosing the right size generator for your needs, consider a few items to help calculate the wattage you’ll need. Start by determining which household items and appliances you want to power, and then add the wattages together. Check out the wattage of these essential appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 watts

Running home appliances like these requires a partial or whole-house generator. A portable generator may be enough to power your home if you only plan to keep a refrigerator and freezer running. 

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.

When installed and used correctly, generators are safe to use. The most critical generator safety tips to keep in mind are:

  • Never use a portable generator inside an enclosed space, as the carbon monoxide exhaust it creates is lethal.

  • Never attempt to connect your generator to your home’s electrical panel independently; hire a professional for this dangerous job.

  • Never overload your generator by connecting more appliances than for which it’s rated; you can damage your generator and appliances or even cause a fire.
