"Since this remodeling was the first remodeling that we decided to do after a long time since we did our last remodeling that required to hire a contractor to do it. The kitchen that we wanted to remodel, need to includes the cabinets, floors, island, counter tops, hardware, paint and lighting. We also wanted to do as many energy efficient features that will help us reducing the bills during time. Our search was for high quality and low quality and reputable construction companies that can service my area. Landmark construction energy crew was the great find that I was able to talk to and hire. First off their service was top notch. They were very responsive from the first meeting we had, patiently and really wanted to know what I’m trying to do in the kitchen. They were in touch with me during the whole work and made sure to provide me with updates regard anything that was complete and what will be next. What I liked most was that they were extremely detail-oriented. I very much appreciated that, especially given the Major scope of my project and plans. The end results were more than I expected. All the low voltage lightings, the special insulation that they used, the extra protection that they installed in the window that I have in the kitchen and more… All of this features improved the energy protection at the kitchen. They followed up with me the following day after all the final documents were signed off by me about the work in order to make sure that I was happy with the final results. I'm happy to mention that kitchen remodeling project was completed a little bit before the due date."

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

"we were very impressed with out solar endeavor. The installers came when they said they would and finished their job within the same day. We added insulation to our attic to reduce our heating and cooling for the house and replaced 2 old windows . All the guys were great from Idan who evaluated our home, office staff and installers. We are very happy. "

"All Pest Pros removed existing insulation, cleaned attic and sealed any potential rodent entry points and replaced w/new insulation.  They also secured the house against rodent ability to access by reconstructing access doors under the house, closed off all exterior rodent entry points around the structure and placed traps to assure the sealing was effective.   Staff was professional, courteous and responsive.  The work was done to our satisfaction.   We live on an acreage w/surrounding acreage properties.  Squirrels, racoons, skunks, mice and rats have multiple places to live.  We've had no rodent or any other animal accessing under our house or in the walls or attic since All Pest Pro secured it."

"Excellent. The rep showed up on time and did a very thorough job, complete with photos and a write-up of all the affected areas. He also gave a quote to perform both the exclusion work and to clean & replace the soiled insulation. I will be calling them to do both jobs shortly."

FAQs for insulation service projects in Oroville, CA

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.
