"Highly recommend Zzeo's Home Restorations. Extremely satisfied with the project work. Has water leakage into the house above the living room double windows. At first thought that the source was a roof overhang above the window. Angel gave an estimate for the work assuming it was the source. However, he warned that source could be from cracks in to mortar of the rock façade and would not know until some of the interior dry wall above the window and the roofing on the overhang was removed. Unfortunately the overhang was not the source of water intrusion. Thus had to remove the rock façade to find the source. Anel gave me a revised estimate for the work needed. So the damaged exterior wood was replace and interior drywall section replaced. The outside section where the rocks were removed was properly waterproofed. Instead of rock had this section replace with bricks. Also since the second floor window just above the leak and the double living room room window were in need of repair or replacement, had these windows replaced. Angel kept us informed as work progressed. His crew were very respectful and knowledgeable. The project results were extremely satisfying. As the project was being completed, my neighbors were very much impressed with workmanship and beauty of the work. Again highly recommend Zzeo's Home Restorations. I anticipate that I will use them for future projects."

"I called Restore You and the owner Art Sulik came to my home at my convenience. He surveyed unerdneath my home and found mold on the floor structure and moisture and water on the ground. He removed the existing insulation, cleaned the wood with hydrogen peroxide product, followed through with an anti microbial. After everything dried they Hepa vac the wood to remove any mold spores which are allergens. Then fogged everything with Timbor fungicide Disodium Ocyabotate tetrahydrate (boron). The foundation walls inside the crawlspace were painted with Dry lok extreme, a waterproof paint. A vapor Barrier 6 Mil was added to the ground. His work was exceptional! I was very pleased. I highly recommend Restore You for any moisture, mold or water problems."

"Mike came and did a thorough inspection of my crawlspace which was once home to a family of raccoons. CleanSpace came and cleaned and disposed of all of the soiled insulation and sanitized the space before installing new and better insulation . The work was done quickly and as described, I would recommend them for anyone in a similar situation!"

FAQs for insulation service projects in Cape May, NJ

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.
