"On initial inspection, they discovered that our old heat registers were the kind with asbestos (house built in the 60's), so they had to sub out the abatement part of the job. Once abatement was complete, the workers showed up each day at the time they said they would arrive. They were all friendly and professional. They kept everything clean. The took pictures in the attic to show me before, during, and after the work. They explained what they were doing and showed me the new ducting they were installing (quiet ducts) and explained the more "up-to-date" way of putting in the duct work than what we had. After the work was complete, we noted that the furnace ran much quieter (due to new ducting), and it ran WAY less often. The house stayed much warmer while running the furnace much less often. Best of all, our gas bill dropped! Now that we're moving into summer, the house seems to be staying cooler on these warm days. We don't have A/C so we're hoping the new insulation will keep the house cooler as the days continue to warm up. Very happy with the company and all the work they did. I would recommend them!"

"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."

"After we returned home from our summer vacation out of town, we found that our master bath and bedroom had flooded due to rain and clogged plumbing. When I called the chief executor of Hometown Restoration, he replied quickly, provided a reasonable quotation, and started work straight away. We were delighted with the accuracy of the treatment of water, as well as the quickness through which his workers restored our master suite after insulation removal, flood cutting, and so on. Our home looked nicer than the original! Staff were professional, kind, and meticulous in their clean-up. I would refer Hometown Restoration to others!"

"They did a fabulous job on the analysis. They were here for 5 and a half hours so it was very thorough. They tested the air flow through the ducts and everything. I was blown away by the thoroughness for the analysis. They were extremely professional and explained why they were recommending what they recommended. They followed up by sending a pdf of their estimate and their explanation. We did not have the company install insulation, but it wasn’t due to their lacking. What they proposed was definitely the best solution."

I purchased a big deal for this service and it worked out good. I just did not really jell with the designer so I did not use them. I did not like his ideas and did not like how they threw out the dollar amount for the project without knowing what I wanted to do. They are good, but it just did not work for me.

FAQs for insulation service projects in San Luis Rey, 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.
