"Great! Job was complete .... removal of existing 50+ year old insulation, air sealing attic, baffle installation, installed 18 inches new fiberglass blown insulation, and new whole-house fan. Job started and completed as proposed. Crew on-time, quietly performed their work, and left spaces clean when done. Definitely worth the cost as noticeable improvement in second floor temperature and humidity readings."

"This is our fourth time using Diaz for our home renovations. He refinished and stained floors and painted several rooms. He also rebuilt an upstairs deck. In addition, he took care of about 10 other little things that needed fixing. As always, Diaz was the best contractor we’ve ever encountered. He came right out for a free estimate. He gave us constructive advice on the proposed work. His crew got started right away - they were reliable, on time, courteous, and cleaned up impeccably each day. Diaz stuck to his estimate. In addition to all these positive traits, one of the best things is that Diaz and his team can literally take care of anything. You will not have to rely on a subcontractor or having to call somebody else - he does painting, flooring, kitchens, doors/windows, drywall work, tiling, bathrooms, etc. He even has his own tree guy and electrician for when those things come up. He doesn’t just do everything, but everything is done to perfection. Highly recommended!"

Old insulation should be removed when it shows damage, contamination, or heavy deterioration. If you notice water stains, rodent droppings, mold, or large gaps, plan on taking it out to protect your home’s energy performance and indoor air quality. Removing compromised material eliminates health hazards, cuts energy loss, and sets the stage for a safer, more efficient attic—all while keeping utility bills in check.
R-value measures how well insulation resists heat flow—the higher the number, the better it slows heat transfer. The right R-value keeps your home warmer in winter and cooler in summer, saving energy year-round. Match the rating to your climate zone and have a pro verify performance over time, because moisture or settling can lower R-value and cut efficiency.
Attic insulation can stay in place for 80 to 100 years, but its performance often drops after the first 15. As dust, moisture, or mold build up, the material loses R-value and allows heat to escape. Schedule periodic inspections so a pro can tell you when replacement makes sense—helping you keep energy bills down and indoor comfort up.
You can over-insulate an attic. Beyond the recommended R-value, extra layers don’t add efficiency and can trap moisture, leading to mold or reduced performance. A local insulation pro can measure current levels, confirm the right target for your climate, and advise on any adjustments so you avoid future energy or maintenance headaches.
Insulation can be damaged by mold, pests, water leaks, or accidental electrical contact. When the material is compromised, it loses R-value and can introduce health hazards. Removing and replacing affected sections restores efficiency, while routine inspections from a qualified pro help you catch problems early and keep your attic safe and energy-smart.
