"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."

"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."

"They did a great job with adding cellulose insulation to by exterior walls. We had some problems getting a hold of the salesman but nothing to complain about or stop us from recommending this company. Great value for the money."

"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. "

Insulation FAQs, answered by experts

The life span of fiberglass insulation can be as long as 80 to 100 years, but because of changing building codes, it’s best to get your insulation checked every 10 to 15 years. Signs of degrading fiberglass insulation include bits of batts on the floor or batts detached from frames. Having optimal, healthy insulation in your home will improve its energy efficiency, lowering your monthly bills.

Insulating a stone house is an expensive and involved process because it requires building a double-walled house. The walls don’t need to be the same thickness, but they both need to be thick enough to handle any structural demands and meet fire and safety standards. The insulation (usually foam or fiberglass) is then installed between the two stone walls.

Spreading tin foil over your windows works similarly to radiant barrier insulation, but not as well. It will reflect some of the sunlight that would otherwise come through the glass and warm up the inside of your home, so it might help a little to keep your home cool in the summer. However, the appearance isn’t preferable to blinds or drapes that can offer the same benefits. You might also consider tinting your windows instead, which is a more aesthetically pleasing change that can still block a good portion of the solar heat coming through your windows.

Yes, you can install insulation behind drywall yourself, but only if your walls are not finished. If your studs are exposed, installing fiberglass insulation in roll or batt form is very straightforward and just requires a few tools and some safety equipment. If your walls are already finished and you’re looking to add insulation, it’s better to hire a professional, as you’ll likely need blown-in insulation, which can be dangerous to work with and a challenge to get into the proper areas in your wall voids.

To keep cold out, look for treatments that sit close to the window frame and are made from thick, insulating materials. Thermal curtains, cellular shades, window quilts, and insulated shutters can all help retain heat. Layering window treatments, like pairing lined curtains with cellular shades, can provide even better insulation by further reducing drafts and heat transfer.
