"I was given several recommendations from Angi list, the most professional one of the 4 contacts I received was from David of EVERGREENPRO INSULATION. I needed to have a couple of interior walls insulated for soundproofing done. David was responsive, answered all my questions and gave me a reasonable quote. The other companies I talked to quotes were inline with Davids but the customer service just wasn't there like Davids. I even had one company tell me my project was too small for them to do..... Really? The next insulation project I need done I will just call David from EVERGREENPRO INSULATION and give them the job. A great job done by David and Jamie and would recommend and use them again."

"I've worked with many companies over the years doing upgrades to veterans homes and other home insulation projects but this company really stood out above the rest. Absolutely exceptional! Professional, high quality, competitively priced and his team did the work beyond my expectations. Completely removed old, contaminated insulation, treated the entire attic to remove mold and other contaminates and then replaced with top quality insulation "to code." I'll be recommending them for any future projects when restoring homes."

"Sergio and his crew timely completed a complex insulation installation. Near Me Insulation LLC gets highest marks for flexibility in terms of traveling from Burlington to Glacier and completing the work with the highest skill level. The inside of my Ski Barn in Glacier has a height of 35 feet at the peak--several rooms with outside walls needed insulation. Sergio and crew also wrapped pipes and replaced window flashing with great care and expertise. Highly recommended contractor--reasonable price."

Insulation questions, answered by experts

Structural insulated panels and rigid foam boards have the highest R-value of any insulation that contractors commonly use, with R-values reaching up to around 8.0. These types of insulation are best in extremely cold climates, but they’re generally preferred for new construction, as they can be challenging to retrofit. Blown-in and loose fill insulation provide the next best insulative value, provided the installation is done properly. It’s important to choose an insulation type that meets your needs based on climate, as maximizing R-value may not always be financially worthwhile if you live in a moderate climate.

A garage ceiling needs a vapor barrier if it’s a heated garage or if you’re installing insulation in the ceiling. Without a vapor barrier, you risk moisture issues and mold growth. If you have an unheated garage and don’t plan on installing insulation that could get wet and harbor mold, the ceiling doesn't need a vapor barrier.

Chimney liners often benefit from insulation, though it is not always required. Insulation helps improve the liner's efficiency by keeping flue gasses hotter, which enhances draft and reduces creosote buildup. It also prevents condensation, which can lead to corrosion. Insulation is important for chimneys on exterior walls or in colder climates. Some building codes may require insulation, so checking local regulations is essential.

The best type of insulation for your home depends on your specific needs, climate, and the area you are insulating. For new construction, structural insulated panels are a highly energy-efficient option that is easy to install during the building process. In very warm climates, reflective insulation can be a cost-effective choice. For cold climates, fiberglass is an excellent option due to its high R-value and resistance to settling over time. Spray foam works well in humid environments because of its moisture-resistant properties. For standard attics, loose-fill, spray foam, or blown-in insulation are all suitable options.

EIFS (Exterior Insulation and Finish System) siding can last from 20 to 60 years, with some properly maintained systems lasting even longer. The exact lifespan depends heavily on several factors, most notably the quality of the initial installation and the consistency of maintenance.

Factors that can shorten the life of EIFS include:

  • Improper or poor-quality installation

  • Moisture intrusion

  • Damage from high winds, storms, or hail

  • Damaged flashing and sealant

  • Lack of regular maintenance and unfixed damage

To maximize the lifespan of your EIFS, it is crucial to hire an experienced and qualified professional for the installation. Additionally, regular maintenance—such as cleaning, repairing small cracks or blisters, and having the system professionally inspected—will help identify and resolve issues quickly, preventing long-term damage.
