Icynene Blown In Insulation in Dallas: What to Know First
Icynene blown in insulation in Dallas typically costs $1,800 to $4,200 for a full attic, depending on square footage, current R-value, and whether we’re installing over existing material or removing it first. Most Icynene jobs we take on are completed in one day, and every quote is a written price before we touch the attic. If you own a Dallas home with Icynene spray foam already in place and need blown in insulation added, replaced, or corrected, we handle that work as an independent Icynene service provider, not a manufacturer affiliate. Call (940) 748-1726 for a straight answer on what your attic needs.

How Icynene Products Fail – and How We Fix Them
Icynene is a well-known open-cell spray foam brand, and its products have performed fine in plenty of Dallas homes. But open-cell foam has a lower R-value per inch than closed-cell, and that’s where most of the blown in insulation callbacks come from. Here’s what we see in the field, line by line.
- Icynene Classic open-cell installed too thin. The Classic line runs about R-3.6 per inch. In a Dallas attic with 2×6 rafters, that’s roughly R-20 at best. Texas code wants R-30 to R-38 in most attics. The fix: we blow Owens Corning AttiCat fiberglass or GreenFiber cellulose over the foam to close the gap. The foam stays, the R-value climbs, and the job is done same day.
- Icynene ProSeal with shrinkage gaps at the roof line. ProSeal was marketed for its air-sealing properties, but in attics that hit 140 degrees in a Dallas August, we see small gaps open where the foam meets the decking. Air leaks through, and the house loses conditioned air. We foam-seal those gaps with a compatible sealant, then blow insulation over the floor joists to add thermal resistance where the ceiling is the weak point.
- Icynene LD-C-50 that never got a top coat. The LD-C-50 line is a lower-density open-cell foam. It’s soft, and it can hold moisture if the attic has a ventilation problem, which is common in older Dallas homes with soffit vents painted shut or blocked by blown in insulation from a previous contractor. We check the ventilation first, correct it if needed, and then install blown in insulation that won’t block the soffits. That last part matters more than people think.
- Icynene H2Foam Lite in unconditioned attics. H2Foam Lite was designed for interior walls and some attic knee walls. When it’s sprayed on the under-roof in an unconditioned attic, the underside of the decking can sweat in Dallas humidity cycles. We see this most often in homes built fast during the 2010s boom. The fix isn’t more foam. It’s blown in insulation at the attic floor level, which keeps the conditioned space below sealed off from the heat above.
- Icynene MaxSense with uneven coverage. MaxSense is the newer open-cell line, and we’ve found it in attics where the installer left thin spots over bedrooms and thick spots over hallways. The symptom is room-by-room temperature swings. We map the attic, find the thin coverage, and build up the weak areas with blown in fiberglass before adding a uniform layer across the whole floor. That gives us consistent R-value instead of guessing.
Our Icynene Blown In Insulation Process
Every Icynene job in Dallas follows the same sequence. Here’s how it runs from the first call to cleanup.
- 1
Call and schedule. You call (940) 748-1726. A live person answers, takes your address and the basics, and sets a window. We show up inside that window, not a vague half-day later.
- 2
Attic inspection and measurement. We measure square footage, check existing Icynene coverage, look at ventilation, and note any electrical or ductwork we need to work around. Bryce Holloway trained on blower-door diagnostics, and on older Dallas homes he’ll check for air leaks before recommending insulation depth.
- 3
Written price. Before any equipment comes off the truck, you get the number. That number is the number on the invoice. No adjustments at the door.
- 4
The install. We blow fiberglass or cellulose to the target R-value using calibrated equipment. If existing Icynene needs sealing first, we do that before the insulation goes in. We protect the attic access, lay down drop cloths in the living space, and keep the job contained.
- 5
Depth checks and cleanup. We verify depth across the entire attic with ruler checks, not eyeballing. Then we vacuum the access area, remove all material scraps and packaging, and leave the house the way we found it.
- 6
Written guarantee. You get the 365-Day Done Right Promise in writing. If anything fails within a year, we come back at no charge. That’s not a sales line. It’s the standard.
What Icynene Blown In Insulation Costs in Dallas
Here are honest ranges for the Icynene blown in insulation scenarios we handle most in Dallas. These are based on typical attic sizes in the area, from smaller 1950s ranch homes in East Dallas to larger two-story builds in Preston Hollow and North Dallas.
| Scenario | Typical Cost Range |
|---|---|
| Blown in fiberglass over existing Icynene (1,000 sq ft attic, R-20 to R-38) | $1,800 – $2,400 |
| Blown in cellulose over existing Icynene (1,200 sq ft attic) | $2,200 – $2,900 |
| Foam seal gaps plus blown in insulation (1,500 sq ft attic) | $2,800 – $3,600 |
| Full removal of failed Icynene plus new blown in insulation | $3,500 – $4,200 |
What moves the price: attic square footage, how much existing insulation is already there, whether we need to remove anything first, and how accessible your attic is. A cramped attic in a Lakewood bungalow takes longer than an open attic in a 2005 build. Call (940) 748-1726 for a free estimate. We’ll give you a number you can hold us to.

FAQs
Yes, and that’s actually the most common Icynene job we do in Dallas. Open-cell foam often tops out below Texas code for attic R-value, so we blow fiberglass or cellulose over it to bring the total up to R-30 or R-38. The foam stays in place, the insulation layer adds thermal resistance, and the job is usually done in one day. Call (940) 748-1726 for a free estimate on your attic.
In most cases, no. Adding blown in insulation on the attic floor does not disturb the Icynene foam that’s sprayed on the roofline or walls. We don’t alter or remove the foam unless it’s already failed and you’ve asked us to. As an independent Icynene service provider, we don’t handle manufacturer warranty claims, but we can document the condition of your existing foam before and after install so you have a record.
Adding blown in insulation is almost always cheaper than full Icynene removal. Removal runs $1.50 to $2.00 per square foot in Dallas, plus disposal, while adding blown in fiberglass over existing foam runs roughly half that. We only recommend removal when the foam has moisture damage, mold, or a ventilation failure that can’t be corrected without taking it out. Get the R-value right, and the house takes care of the rest.
For most Dallas neighborhoods we can schedule same-day or next-day appointments. Calls are answered by a live person 24/7, so you won’t leave a voicemail and wait. We service Lakewood, Lake Highlands, Preston Hollow, Oak Cliff, East Dallas, and the northern suburbs.
Every job includes the 365-Day Done Right Promise in writing. If the work fails within a year, we come back and make it right at no charge. That includes a free second visit if a repair fails inside the guarantee window. No fine print, no prorated nonsense.
