"Great. Jeff quoted our specs, & did an in-house visit. He reviewed the entire project. He made sure Our expecting were realistic, before going on. Everything was clear, & got a competitive price.. We have noisy upstairs neighbors in Condo yelling & loud TV, RADIO,MUSIC & the project helped reduce it by 30-65%. It is hard to be specific without decipel meaning equipment. The cellulose bags say 60%, however Jeff pointed out expect 35%- that honesty, eventhough we got better. If you do a similar job, make sure you understand IMPACT noise, which is not what this project can do. So we are not disappointed, & got what we asked for. The noise was reduced, but not eliminated. This will keep us in a holding spot, in that we might not have to move for now, as moving is very expensive. This kind of improved our quality of life. Our contractor Juan & Dillon were Professional, respectful of our home & exceeded all posted reviews. "Was money paid or were services performed?*-bad question!"

Insulation questions, answered by experts

It depends on your needs and preferences, though many homeowners think it is worth it. Not only is blown-in insulation easy to install, but it is highly efficient with thermal regulation. Most types are mold-resistant, flame-resistant, insect-resistant, and, most importantly, completely safe.

Yes, insulating your cold water pipes is a great way to prevent condensation. When warm, humid air meets cold pipes, condensation forms, which can drip and cause moisture issues in your home. Pipe insulation acts as a barrier between the warm air and the cold pipes, keeping condensation at bay and helping you avoid potential problems like mold or structural damage.

Closed-cell foam may come with a higher price tag, but it’s worth the investment because of its strength and durability. This material offers excellent thermal and moisture resistance, contributing to its long life span. Its construction enhances energy efficiency, which can lead to reduced heating and cooling costs over time.

A vapor barrier keeps moisture out of the crawl space, while insulation reduces the amount of unconditioned air—and sometimes moisture—that enters the space. Coupling a vapor barrier with insulation can help prevent humidity and related moisture damage in a crawl space while also making your home more energy-efficient. Just be sure to use insulation that won’t get damaged from moisture, like rigid foam board or expanding spray foam insulation.

Regular inspections for moisture damage, pest infestations, and proper R-value performance help maintain efficiency.
