"Matt was very good about keeping all appointments and very friendly. His work on the insulation was nice and neat and very effective. Good adhesion in all surfaces, and he even made a special trip back on our small job to finish insulating several windows. Matt gave the best service and best product of all the contractors I’ve had to hire in the last year. We may ask him to come back and insulate the rest of the garage!"

"Sergio the estimator arrived on time was exceptionally thorough. I was only looking for attic insulation, but Sergio asked if I had insulation in my walls. I assumed I did, he checked I did not, as I have an older home. Jon was wonderful answering my questions and calls. Luis and Jose arrived on time they did a fabulous job insulating my attic and walls and were very neat and clean I needed some help clearing some shelves in the garage for wall insulation and Jon sent his son Connor help me. I highly recommend them"

"Good customer service and were flexible when scheduling the work to be done. Can already feel a bit temperature difference in the attic where the insulation was done and the finish job makes the attic very bright. We have gained valuable space having had this work done."

"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."

"Right from the get go Brian was very helpful. He was very up-front and patiently explained all the kinds of insulation and suggested which ones to use. He even went so far as to include the inside wall insulation for soundproofing at no cost since the project was large. Very easy to work with and flexible."

"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."

Insulation FAQs, answered by experts

Insulating under a concrete slab foundation is a great way to improve the energy efficiency of your home, but it isn't necessary for outdoor projects like driveways, patios, sidewalks, and walkways. If you’re pouring in cold weather, insulating under the slab can help prevent heat loss from the concrete, aiding in proper curing. Along with accelerants, this can be a good way to ensure strong concrete despite pouring in the cold.

Garage door insulation can last anywhere from 20 to 100 years depending on the type of insulation. Cellulose has the shortest lifespan coming in at between 20 and 30 years, while spray foam, mineral wool, and fiberglass can last between 80 and 100 years with proper maintenance. 

Humidity plays a role in how long more susceptible insulation materials—like fiberglass—last. Once fiberglass batts reach the 15-year mark, you'll need to routinely inspect your insulation to ensure that it is in mint order.

For standard 2x4 walls, the ideal insulation has an R-value between R-13 and R-15. This level of insulation, typically around 3.5 inches thick, fits well within the wall cavity. Common options include fiberglass batts and spray foam. The best choice for your home can depend on your climate; use R-value maps, like those from Energy Star, to determine the recommended level for your region. For colder climates, you might also consider adding exterior insulation for greater efficiency. Always check with your local building codes to ensure you meet any required standards.

Without a doubt, insulating a garage door is a surefire way to make your home more energy efficient. Not only does insulating your garage door reduce your electric bills, but it also helps protect your valuables inside your garage, all while making for a quieter interior space. 

In regions that drop below 0 degrees Fahrenheit, your car's battery is at risk of malfunctioning in a garage that drops dangerously low. So, homeowners who reside in extremely cold climates can especially benefit from insulating their garages.

Insulating your ducts offers several benefits, including:

  • Improved energy efficiency: Duct insulation prevents energy losses, reducing heating and cooling costs.

  • Cost savings: Lower energy bills make insulation a cost-effective investment.

  • Environmental benefits: Enhanced efficiency reduces your carbon footprint.

  • Consistent comfort: Insulated ducts help maintain a stable indoor temperature.

  • Better indoor air quality: Reduced allergens and pollutants improve air quality.
