Diamond Certified Resource Compared to Crowd-Sourced Review Sites

Diamond Certified Resource’s ratings of local companies are based on surveys of only verified real customers, so they are the most accurate. This beats crowd-sourced review sites like Yelp, Angi or even Google that are plagued with fake, manipulated, cherry-picked and non-customer reviews, which produce inaccurate and often inflated rating scores.

Diamond Certified Resource’s deeply researched reports of top rated Diamond Certified companies include everything you need to see to be very confident in choosing a top rated local company. Each company report includes detailed quality ratings and scoring, verbatim customer survey responses, a profile video, a company story video, a capabilities table, a photo gallery, researched articles, unique expert contributions from the company’s owner, and more.

This sounds good, but it has led to company profiles that are littered with false claims and incomplete info.

A: Diamond Certified insulation contractors use top-quality brands like Roxul, Johns Manville, Insulfoam, Icynene and Owens Corning.
Q: What types of wall insulation do insulation contractors offer?
A: Insulation contractors offer several types of vapor barrier installation, including spray foam, loose fill, sheet metal, and plastic film. Spray foam is a polyurethane foam that is applied directly to the undersides of walls and ceilings and forms a continuous air and vapor barrier. Loose fill insulation, such as fiberglass or cellulose, is blown into the wall cavities to form an air and vapor barrier. Sheet metal vapor barriers are usually installed behind the insulation and can be used to create an airtight seal. Finally, plastic film vapor barriers are installed directly over the insulation and can help prevent the entry of moisture and air.
