"The type of work I needed done was literally beyond over 12 other companies I had to my home for an estimate. Some very popular companies (which are supposedly experts) at cleaning up the situation I had in my basement. The situation: Foam Insulation that was sprayed in all the Wellâ s / Between All Jointâ s through out the entire basement of a 3 Bd Rm Ranch. The Foam HAD to be removed due to Termites. All Exterminatorâ s stated the Termiteâ s could not be treat until the Foam was removed. To my complete surprise and obvious delight that they took the job was beyond wordâ s. Some very (as they stated) were the best â ¦ yet some actual stated; â Ummm -,I never seen this nor been ask to remove it.â One company wanted $250 for the first hour and $150 for each additional hour - with a quote of taking 3 dayâ s to complete the job. The estimate for the job never exceeded more than 1 day -,there was no surprise or statementâ s that it was an impossible job to do. They arrived on time - - took 2 / 10 minute breaks and completed everything within only several hours. I was absolutely amazed and thrilled. Professional and completely committed to finish the work. I absolutely recommend if your in need of anything foam insulation. Even removal. Iâ m extremely happy with the work and the professionalism. An absolutely top rated company and recommended if you need anything foam insulation related you to look no further. Thank you so very much for all the work you did! ."

"These guys are great! Manny showed up on time for his estimate, gave me a price on the spot, and talked things out with me to make sure that I understood exactly what he was including in the insulation project. He was able to meet my timeline, which was quick, and finish the project on time and as promised. He was very communicative throughout the process and pleasure to deal with. His crew was polite and worked hard. I am VERY satisfied with the crew and the workmanship."

Insulation questions, answered by experts

In some areas, insulation companies require a special license, while some states only require them to hold general contractor licenses. Some municipalities may not mandate any license, although you should always ensure a contractor is fully insured. You can use Angi’s license lookup tool to confirm whether or not an insulation contractor you’re considering holds the necessary license for your area. You can also contact the company for information regarding licenses, certifications, and insurance.

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.

Most insulation lasts 15 to 20 years, but it really depends on the type of insulation. Spray foam is a permanent insulation material that can last up to 100 years. Fiberglass and cellulose typically settle, shift, or deteriorate around 15 years. Once your insulation reaches the 15-year mark, it's time to check it for signs of needing to be replaced.

The most affordable way to insulate a garage involves choosing cost-effective materials like fiberglass, which comes in batts or rolls and is relatively easy to install. You can often install this type of insulation without needing to add drywall, which helps reduce costs. While a DIY approach might seem cheapest, hiring a professional installer can be highly cost-effective. Experts can accurately determine your garage's specific insulation needs and ensure the best results for your investment, often using batt insulation for the bulk of the project.

A vapor barrier keeps moisture out of the crawl space, while insulation reduces the amount of unconditioned air—and sometimes moisture—that enters the space. Coupling a vapor barrier with insulation can help prevent humidity and related moisture damage in a crawl space while also making your home more energy-efficient. Just be sure to use insulation that won’t get damaged from moisture, like rigid foam board or expanding spray foam insulation.
