HOMR rated over 70 Dallas insulation companies on local service data, range of services, financing options and a measurable record of increased home energy efficiency. We selected Koala Insulation of North Texas as our top pick for cellulose insulation installation services. We chose Blown Away Insulation as our best Dallas provider for new fiberglass insulation.

The rise of extreme hot and cold weather in North Texas means homeowners are clamoring for insulation installation services. We think fiberglass insulation and cellulose insulation are the 2 most cost-efficient solutions for most Dallas homeowners.

Here's what we'll cover in this updated hiring guide to Dallas insulation companies:

  • HOMR Data and Research: HOMR scheduled and managed 10 DFW insulation projects last year and reviewed 70+ insulation companies.
  • Most Popular Dallas Insulation Types: Most Dallas homeowners choose insulation batts, spray foam insulation, and blown-in insulation for their homes.
  • Dallas Insulation R-Value Requirements: Current Dallas building code requires R-49 in an uninsulated attic, R-38 in most attics with existing insulation, and R-19 in floors.
  • How to Choose a DFW Insulation Installer: Learn why price point, years of service and strong relationships with insulation manufacturers are our top considerations.
  • Insulation Company Red Flags: The top 3 BBB complaints against Dallas insulation companies are invasive installation, poor communication, and bad attic insulation.
  • How Much Does Dallas Insulation Cost? The average cost to install new insulation in a 2,000 square foot home is $3,000-$5,000 for blown-in insulation, $4,500-$6,500 for batt insulation, and up to $10,000 for spray foam insulation.
  • Our Top 2 Dallas Insulation Companies: We chose Koala Insulation as the best cellulose insulation provider, and we like Blown Away Insulation as the best DFW fiberglass insulation installer.

The Data and Research: Why You Should Trust Us

Last year, HOMR scheduled and managed 10 Dallas Fort Worth home insulation jobs. These projects covered the following categories:

  • Blown-in cellulose insulation (new installation)
  • Fiberglass insulation (new installation and replacement of existing insulation)
  • Open cell and closed cell spray foam insulation
  • Insulation removal services

HOMR also performed 7 home energy consultations with Dallas homeowners. We reviewed the biggest drivers of home inefficiencies to highlight ways that replacement insulation could increase energy efficiency in DFW homes.

These consultations and service offerings gave HOMR exclusive data in the Dallas insulation service industry. We used this data to identify and analyze the top 3 types of insulation currently used in Dallas area homes.

Top 3 Home Insulation Types in Dallas Homes

The 3 most popular types of home insulation in the Dallas-Fort Worth area are fiberglass insulation batts, blown-in cellulose insulation, and spray foam insulation.

Table: Texas Requirements for Home Insulation R-Value

Insulation Location Insulation R-Value Required in Texas
Uninsulated attic R-49
Attic with 3-4” of existing insulation R-36
Floor R-19
Uninsulated wood frame wall R-5 (beneath siding)

The information above is based on the updated Texas building code

R-value is a measurement of how well insulation prevents heat from entering and exiting your home. We'll cover how much of each type of insulation is needed to meet the current building code in Dallas.

Need a cost breakdown for your Dallas home insulation project? Check out the updated HOMR Cost Guide to home insulation materials and see whether fiberglass, cellulose or spray foam is right for you.

Batt Insulation

Fiberglass batt insulation installed in home ceiling, used to demonstrate batt insulation in Dallas.

Batts are insulation cut into flat pieces that are sized to fit into standard-sized spaces between beams and studs. Unlike rolled insulation, batts are installed in individual pieces and aligned to fit snugly in your wall, floor and ceiling spaces.

Most residential batt insulation is made of fiberglass or mineral wool. Less frequently, you'll see batts made from plastic fibers or natural fibers. Some modern fiberglass batt insulation is hypoallergenic, eliminating the dangerous itchy material found in older fiberglass insulation.

How Much Batt Insulation Do I Need in Dallas? Based on the current building code, you need the following amounts of batt insulation:

  • Uninsulated attic: R-49 batt insulation is between 13 ¾" and 14" thick .
  • Attic with 3-4 inches of existing insulation: R-38 batt insulation is between 10" and 10 ¼" thick.
  • Floor: R-19 batt insulation is between 6" and 6 ¼" thick.

Blown-In Insulation

Blown-in insulation is a collection of loose-fill material that's primarily found in walls, crawl spaces and attics. It's best used when blown into areas that are difficult to reach, where rolled or batt insulation is tough to install.

Blown insulation is generally made from cellulose, fiberglass or rock wool. It's important for your blown insulation installer not to overfill hard-to-see areas with insulation, as this can decrease the energy efficiency of your space.

The primary downside to blown-in insulation is the amount needed to reach current R-value standards. The upside? It's usually the cheapest of the 3 primary insulation installation options.

How Much Blown Insulation Do I Need in Dallas? Based on the current building code, you need the following amounts of blown-in insulation:

  • Uninsulated attic: R-49 blown-in insulation is 16 ¼" thick.
  • Attic with 3-4 inches of existing insulation: R-38 blown insulation is 12 ¾" thick.
  • Floor: R-19 blown insulation is 6 ¾" thick.
ECO-FRIENDLY TIP: Recycled cellulose insulation achieves a carbon footprint reduction of 210% over other insulation types, according to a 2023 report from Builders for Climate Action.

Spray Foam Insulation

Spray foam insulation consists of a polyurethane foam that's sprayed into walls, ceilings and floors as insulation and an air barrier. It's simple to install, even in tight spaces like door frames, window frames and near light fixtures.

Spray foam is excellent at retaining its shape and is a top-quality air sealant. It eliminates wall condensation, so mold and mildew concerns are irrelevant. You'll pay a high price for this highly-efficient material — spray foam insulation can cost 4-5x as much as fiberglass and cellulose options.

Spray foam insulation is also more expensive because it takes up far less space than cellulose and fiberglass. Closed cell spray foam covers roughly R-6.5 to R-7 per inch of foam. Compare that with R-3.8 per inch of fiberglass batts, and between R-3 and R-3.5 per inch of cellulose.

How Much Spray Foam Insulation Do I Need in Dallas? Based on the current building code, you need the following amounts of spray foam insulation:

  • Uninsulated attic: R-49 closed cell spray foam insulation is between 7" and 7 ½" thick.
  • Attic with 3-4 inches of existing insulation: R-38 closed cell spray foam insulation is between 5 ½" and 5 ¾" thick.
  • Floor: R-19 closed cell spray foam insulation is between 2 ¾" and 3" thick.

How We Ranked the Best Dallas Insulation Companies

We began our Dallas insulation contractor rankings by eliminating all service providers without a substantial work history over the last 3+ years. We also didn't consider any contractors with outstanding BBB complaints or complaints filed with Dallas City Hall.

Next, we ranked companies on their insulation material offerings. We chose companies that offered more than spray foam insulation, as spray foam is not affordable for every Dallas homeowner. 

We also preferred companies using materials that prioritize indoor air quality, such as hypoallergenic fiberglass and cellulose coated with boric acid.

HOMR gave preference to companies that value home energy efficiency. We looked for a track record of reduced air leaks, as well as vapor barrier and radiant barrier services. 

Finally, we looked for service providers with a clear, transparent communication process. How easy is it to get their core staff on the phone? How promptly were our messages taken and returned? Were the contractors happy to provide information about pricing, financing and service data?

Top BBB Complaints Against Insulation Companies

HOMR analyzed recent insulation service complaints with the Better Business Bureau (BBB) to inform our industry research. We found the top 3 types of complaints lodged against residential insulation companies:

  • Invasive installation. Homeowners often complain about holes left in flooring and attic roofs, as well as walls being blown out and poorly repaired. When possible, opt for an installation service that requires little to no cutting into your existing home structure.
  • Poor communication. Nothing's worse than finding a problem and getting ghosted by your insulation company. Establish a primary point of contact during your interview process to create a clear line of communication for questions and dispute resolution.
  • Poor attic insulation. Up to 40% of potential home heating loss happens in the attic. If you're insulating your attic, work with a contractor with a lengthy, well-documented work history of successful attic insulation projects.

Green Flags

Extensive Experience in Residential Insulation, Including New Installation and Insulation Removal

Clear Communication Regarding R-Value and Material Options

Proven Track Record of Reducing Home Energy Bill Costs

Extensive History of Performing Proper Attic Insulation

Additional Insulation Services (i.e. duct cleaning, sealing air leaks)

✅ Willingness to Provide Financing Options and Information on Government Credits

Red Flags

🚫 Invasive Installation Methods (large holes in floors, blown-out walls and attic spaces)

🚫 No Single, Direct Line of Communication

🚫 Insufficient History of Working in Attics and Other Key Insulation Areas

🚫 No Direct Relationship with Insulation Manufacturers

🚫 Improper Disposal of Old Insulation Materials (or no insulation removal services)

Above and Beyond

Our top picks for Dallas insulation services go above and beyond most service providers with their insulation financing options. This is important due to the increasing cost of new insulation installation in the Dallas-Fort Worth Metroplex.

The average cost to install new insulation in a 2,000 square foot home is $3,000-$5,000 for blown-in insulation, $4,500-$6,500 for batt insulation, and up to $10,000 for spray foam insulation.

HOMR's top 2 residential Dallas insulation companies provide multiple financing options for homeowners on a budget. They also publicly share information regarding the Inflation Reduction Act and energy efficiency home improvement credits on their websites. We like their willingness to pass along high levels of savings to Dallas homeowners.

Meet the Top 2 Dallas Residential Insulation Companies

HOMR selected Koala Insulation of North Texas as the best DFW cellulose insulation company, and Blown Away Insulation as the top Dallas fiberglass insulation company. Here's why.

Koala Insulation of North Texas: Best DFW Cellulose Insulation

Why We Like Them: Koala Insulation prides itself on being prompt, clean, experienced, knowledgeable, and trustworthy. They aced our rankings for courtesy and professionalism. It's never a problem to get the owners or core office manager on the phone to discuss project details and potential issues.

We really like Koala's cellulose insulation materials. Their cellulose is formulated with a boric acid coating, which acts as a repellent against rodents and home pests. You won't find any unwanted guests living in your insulation!

Non-negotiables: We value Koala Insulation's lifetime warranty on workmanship — which goes beyond insulation products to cover the work performed on your home. 

Koala Insulation also goes above and beyond when removing old insulation or other debris from your home. Their white glove service guarantees a spotless home after your project, with everything returned exactly as it was.

Blown Away Insulation: Best for Dallas Fiberglass Insulation

Why We Like Them: Blown Away Insulation scored big in our energy efficiency rankings. Their owner, Cody, spoke to us at length about how proper insulation and air sealing directly impacts your home energy cost.

“When your home is poorly insulated, it's the equivalent of leaving one window fully open all day," Cody explained. “Proper insulation can save you 18-20% on your energy bills.”

We ranked Blown Away Insulation highly for transparent communication, ease of scheduling, and material options. And they know how to engage with customers (the pictures above prove it!)

Non-negotiables: HOMR likes that Blown Away Insulation is owned and operated by a Dallas family. Their approach is personal and respectful, and (like Koala Insulation) it's never a problem to get in direct contact with their ownership and core support staff.

Blown Away Insulation offers a strong variety of financing options for homeowners. They also conduct professional home energy audits with a Blower Door Test. These audits ($300 value) are complimentary when considering one of their service packages.

Honorable Mentions

These 2 companies just missed the cut in our HOMR Dallas insulation company rankings. However, they provide good value in certain areas, especially air quality and holistic HVAC system services. We frequently update our service provider rankings — come back to this Buying Guide in the future and see if our recommendations have changed!

Energy Attic: We liked Energy Attic's wide array of insulation services, including radiant barrier and solar ventilation. They also score well on green energy and energy efficiency. We were unable to reach them on our first call to their listed number.

Garland Insulating: Garland Insulating serves Dallas, Houston and Austin, Texas. They are well-rated for their specialty house wrap and crawl space insulation services. They prioritize spray foam insulation services, which we did not feature heavily in this Buying Guide due to the high price tag.
