"Javier who owns Dixie Insulation was very professional, and went out of his way to make me happy. I must admit, I'm very picky, but Javier's crue were punctual, and did a first class job. I had my old insulation taken away, and I went with the hard foam. There was hardly any smell, which I read, was because, it was properly mixed. I had one, or two small issues, in which Javier took care of them immediately. I highly recommend Dixie Insulation!"

"Did a great job on the insulation however they left a hole in the ceiling when they dropped something on the attic floor. Not a big deal but they need to be careful. Overall, amazing work they do all kinds of insulation and they also install radiant barriers on roof joists. They are reasonably priced and the crew is super friendly, pleasure to work with."

"I highly recommend Fabiano's Construction. Our experience with him was fantastic from beginning to end. The project was to restore and replace the exterior window frames of our 1830 Trinity. The previous owners had installed new windows on the inside but left the old ones outside for beauty. Many of these old windows were completely rotten at the bottom, barely holding the small panes of glass together. We got three estimates. One builder wanted to replace the old windows with a second set of new ones. Another was going to patch them up with wood filler. Fabiano was the only one who was willing to actually restore them, using green wood for the parts that were beyond salvaging. It was precision carpentry work requiring problem-solving ingenuity. The new frames and sills are green wood plus Azek (PVC), so they should last forever. Although more major restoration was necessary than foreseen, Fabiano and his crew—his son Will and assistant Simon—still finished the job in the predicted time. They were careful, focused, hard-working, and also really nice, honest people. It was a pleasure to meet them, and the result is a stunning improvement to our house both inside and out. Fabiano is responsive and friendly, an expert who takes pride in his work. Incredibly, his price was the lowest the three. We plan to hire him for another project."

FAQs for insulation service projects in Clayton, DE

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.
