Here at Maranatha Home & Assemblies no job is to big or to small. We do work from Assembling indoor and outdoor furniture and even exercise equipment. we do installations of lights, ceiling fans, shelving, vanities, faucets, etc. Repairs are also up our alley. anything from damaged drywall, garbage disposals. Lastly we build as well. things like pergolas, sheds, kids play sets, and swing sets, etc.

"Initially, the water company detected a leak on my plumbing, so I hired a professional to come and check it. When he came, he smelled gas in my house, he then said that he did not feel comfortable coming in, so I opened the windows to let the air out. He checked the stove and said there was no gas regulator on it and it did not have a yellow gas whip line. It's not up to code, not up to standard. I then called him back to fix it and he tried to charge me another $125 service charge. I told him I was not gonna pay him to fix his mistake. We went back in forth and then he's asking me what he needs to make it work. When he agreed to comeback, finally, on Christmas Eve, he was three hours late, no phone call, no nothing. Asked me to be here early, I did that coming out from Myrtle Beach. But when he turned the gas off and turned it back on, it did not like the pilot and it filled my house with gas yet again. And he was just rude as anyone can be. I stand by my statement and I have the texts to back it all up."

Insulation questions, answered by experts

While adding insulation can be beneficial, there is too much of a good thing. Too much insulation can seal your house to the point where it can't release moisture that enters it—essentially trapping water vapor inside. Warm, humid climates are extra susceptible to mold from moisture issues, but homes in colder climates can experience condensation from an air-tight home when freezing temperatures thaw.

STC (Sound Transmission Class) ratings tell you how well something blocks airborne noise. It’s a single number that sums up how much sound a material, like a window, can stop across regular speech frequencies. The higher the number, the better the sound reduction. A typical single-pane window hovers around STC 25 (where you can hear normal conversations), while well-sealed, double-pane options can push past STC 45 (which blocks out loud speech and most music). Just keep in mind that STC doesn’t cover everything—low rumbles like bass or thunder can sneak through—so pairing methods are always ideal for the most peace and quiet.

The best R-value for home insulation depends on where you live and where you’re installing the insulation. Your climate zone plays the biggest role in determining the correct R-value, so be sure to know which zone you live in when determining the R-value you need.

The easiest way to cover your HVAC ducts during construction is to use painter’s tape to affix plastic sheets over your vents and air returns in the area of your home where construction will take place. Keep in mind that closing off a portion of your system can put strain on your blower motor and air handler, so either shut the zone off or shut your system off while construction is underway. If you shut the zone, you can also hang plastic sheets over doorways to separate the construction area and keep dust contained.

At a minimum, blown-in insulation lasts 20 to 30 years. Cellulose and sheep’s wool come from natural materials, so they likely max out at around 30 years. Fiberglass and rockwool feature artificial materials that boast lengthy lifespans, up to 50 years, or even longer in some cases. As always, this timeline assumes you don’t run into any issues, such as flooding or mold, that shorten the lifespan.
