We are a united TEAM, 100% committed to raising the bar to provide Service A Better Way, Every Step of the Way.

"I have a home warranty on my recently purchased home. The home warranty company contracts with BWS. The tech, Ryan G, came to my house on 6/24/21 to assess the plumbing issues I discovered after I purchased my home. He told me on 6/24 he would be requesting approval from my home warranty company for the repairs/replacements, then they would need to order parts, and once the parts arrived, would be able to schedule the service. It is 7/8/21. I have been trying to find out from my home warranty company about the delay. I was informed today by my home warranty company "regarding your plumbing request, the technician has not submitted a full diagnosis, but he did call in to advise us that this was a flipper house that was purchased as is and there was no inspection done on the home. I have requested the diagnosis from them. I will follow up with you once it is received." This comes as a HUGE surprise to me as I purchased the home for myself, for me to live in. The housing market is tough right now and many buyers are bypassing inspections so their offers don't get passed-over by sellers. It is definitely a fixer-upper since it was a cat and hoarder house that had been neglected for over 5 years by the previous owner. Someone prior to that owner had done quite a few DIY projects. The house has good bones and needs cosmetic work (flooring, walls, trim). I previously owned and lived in a 110 year old house for over a decade and did many of the renovations myself. I have YEARS of plans to make my new house and yard exactly what I want and need. After the purchase of my house, I had ripped out all of the cat-hair-and-grime-covered flooring, window trim, baseboards, and window treatments. And then I broke my arm. Now most of the projects I had planned are on hold as I cannot use my left arm for anything for at least a few more months. In the meantime, for my home to be ready for me to move in, I need some plumbing issues fixed that I discovered after the purchase of my home. Hence the request for repair through my home warranty that was sent to BWS. While the tech was at my house, I was displeased with his attitude and the way he spoke with me. He treated me as though I were unintelligent, didn't know what I was asking about with my house, didn't know what my home warranty contract covers, and was very dismissive. BWS has not performed any service. They have not followed through with making the request for approval of repair/replacement through my home warranty company. The BWS tech instead took it upon himself to go out of his way to call the home warranty company make false statements to them about me, my house, and my property. I sure hope this is not the type of customer service BWS does for everyone. But then maybe he treated me this way because I am female and have a broken arm."

Energy Efficiency Auditing questions, answered by experts

Window AC units use a fair amount of electricity during use, but the usage pales in comparison to central units. As a matter of fact, window units use around a third of the amount of energy as a central AC. On average, a window air conditioner costs between $15 and $40 per month to run, though this depends on a number of external factors.

There are several signs that your house might have poor ventilation, including lingering odors, condensation on your windows, or mold and mildew. Your home may also feel stale and stuffy, or you might have trouble maintaining a comfortable temperature in your home. On top of that, you might develop allergy symptoms, such as sneezing, coughing, or headaches.

You can determine what size generator you need by listing the various appliances it will power during an outage. Write down the start-up watt usage, and then add them all together. 

A 7,500-watt generator will run your refrigerator, freezer, well pump, and lighting circuits without a problem. However, you’ll need an extra 3,000 to 4,500 watts to run your water heater and another 5,000 to 25,000 watts to run your electric furnace. In these instances, a whole-home generator is your best bet for running your critical equipment.

As you look for the right soundproofing drywall for you, you’ll likely come across the Sound Transmission Class (STC) rating. This rating measures a building material’s ability to absorb sound. The higher the number, the better the material absorbs rather than reflects sound, reducing noise transmission. The STC rating for drywall doesn’t mean it’s for the panel itself—it refers to the STC rating for the entire wall system, including the soundproofing drywall.

Costs depend on the property size, audit complexity, and whether additional testing (e.g., blower door) is included.
