"Outstanding service and quality work. Very thorough work included sealing fixtures, posting measurement guides to confirm insulation depth, and wrapping ducts as required. Provided clear explanation and photos of all work being done. Protected the floors with drop cloths and ensured work areas were completely clean after job. Very highly recommended."

"We are a large family, and require heating and air conditioning, HVAC, throughout the year. At the same time, we were looking for a solution that would not cost us an arm and leg. So without hesitation, we consulted with Charlie from Landmark Energy Upgrades. Charlie, was referred to us by my sister in law that used them in the past for a similar work. Landmark Energy Upgrades really proved to be energy efficiency experts and audited our home thoroughly while patiently answering our questions. They not only made us aware of the total energy consumption, but also how we can cut down the utility bills. Charlie and his team have been accommodating in finding the right solution for us while totally staying within our estimate.

"The workers did the work well. I added more attic insulation, install walkways in the attic, seal our two crawl spaces My only issue was the salesman would never get back to us with the before and after air tightness results. I wrote down the raw numbers when the workers did the air tests, but they promised 6 times that the salesman would get back to me on the final results and impact it should have on our bills. Workers great, office terrible."

"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. "

"An unanticipated extra expense, but they removed all attic insulation and pumped in new insulation with 3X the protection. Closed up all possible entrances into house; made three trips. So far, no signs of these pests, but they say call anytime if I see signs. I'm moving and I can't -- with good conscience -- sell this house to others knowing it had rodents, although it didn't seem to bother the people I bought the house from."

Insulation questions, answered by experts

It’s best not to install a radiant barrier directly under insulation because it requires an air gap on at least one side to work properly. Instead, you should install the radiant barrier over your existing insulation to create an air space to reflect the radiant heat.

Mineral wool has an excellent life expectancy of up to 50 years, provided it's kept dry and free of pests. Compared to fiberglass, with a life span of 20 to 30 years, mineral wool stacks up well for long-term cost savings. Sheep wool maintains a similar life span to fiberglass, while estimates for hemp wool insulation life expectancies are all over the board, ranging anywhere from 20 to 100 years.

Doubling the insulation in your home also doubles the R-value of said insulation. In other words, by adding more insulation, you can reduce the heat loss by half. Most homes benefit from increasing insulation. Older homes, in particular tend to have less insulation as is, so doubling your insulation could drastically reduce your energy bills, keep your home more comfortable, and take the strain off your HVAC system.

Although the cost might seem high, winterizing your home is important for your health and the structural integrity of your home. Winterizing will keep your home warm and toasty during the cold months and prolong the life of your appliances, windows, pipes, sprinkler system, pool, and more. 

Natural fiber batts and spray foam insulation both work great for soundproofing. Newer materials, such as hemp batts, are more expensive but more effective for insulation and sound blocking. They are also more sustainable. There is also a professional system called Blow-In Blanket Insulation (BIBS) that is soundproof and moisture-resistant. However, BIBS must be installed professionally and can be a costly investment.
