One thing that separates us from most insulation contractors in the Leander area: we air seal first, then insulate. That order matters more than most homeowners realize. Blowing insulation over an unsealed attic floor is like weatherstripping a door that’s missing its frame. We complete the air sealing – top plates, penetrations, recessed lights – before a single bag of insulation goes in. On every applicable job, we publish before-and-after blower-door numbers so you can see the actual performance change, in a single measurement, not just take our word for it.
We’ve been independently owned and operated under The Haven Standard since 2016, and in that time we’ve completed work on more than 9,000 homes – each one with a written price before the job started and a documented photo record when we left. Our 365-Day Done Right Promise backs every completed job: if it’s not right, we make it right, in writing.
If you’ve already got a competing estimate, bring it. We offer a Free Second Opinion on any written estimate – we’ll read it with you and tell you exactly what we see. That’s Haven Standard, not a promotional offer.

Same-day availability opens up when schedules allow – call (737) 252-7159 and we’ll tell you exactly what we have. A live person answers 24/7, so you’re not leaving a voicemail at 9 p.m. and waiting two days for a callback.
Leander’s climate plays a real role in how urgent Attic Insulation Replacement becomes. Summer attic temperatures here regularly reach 140-160°F, and when insulation is thin or damaged, that heat load transfers directly into living spaces and drives up cooling costs faster than most homeowners expect. Cedar Park and Brushy Creek homes built in the early 2000s often came with R-19 or less in the attic – well short of the R-38 to R-60 range that Austin Energy and most energy auditors now recommend for this climate zone. We see this routinely, and the blower-door numbers before sealing usually tell the same story: more conditioned air leaving the building than the HVAC system can keep up with.
Our materials come from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber. We don’t lock you into a proprietary product. What goes in your attic is chosen based on your home’s specific conditions, not what we have the most of on the truck.
Areas We Cover
Our primary service area is centered on Attic Insulation in Leander, and we cover the broader corridor of communities that make up northwestern Travis and Williamson Counties. That includes Cedar Park, Brushy Creek, Jollyville, Lago Vista, Georgetown, Round Rock, and Wells Branch. If you’re on the edge of these areas and not sure whether we reach you, call (737) 252-7159 – we’ll confirm coverage before you waste time filling out a form.
Homes across this region share some common characteristics that affect insulation performance: slab foundations, two-story layouts with complex attic geometries, and a mix of blown fiberglass and open-cell spray foam that was installed during the building boom of 2003-2015. In Lago Vista especially, we regularly see homes where attic bypasses around fireplace chases were never sealed – a detail that doesn’t show up on a visual inspection but becomes obvious the moment we run a blower-door test. In Jollyville and Wells Branch, older stock from the late 1980s frequently has vermiculite or deteriorating batt insulation that needs removal before anything new goes in.
Every community in our service area gets the same written scope, the same documented photo record, and the same 365-Day Done Right Promise. The crew doesn’t change based on zip code.
Before
AfterWhat Attic Insulation Costs in Leander, TX
Most attic insulation jobs in a standard Leander-area home run between $1,200 and $3,800, depending on square footage, current insulation condition, access difficulty, and whether air sealing is needed first. Below is a tighter breakdown by job type:
| Job Type | Typical Range (Leander Market) |
|---|---|
| Blown-in fiberglass top-up (1,500-2,000 sq ft attic) | $800 – $1,400 |
| Full attic air seal + blown-in insulation | $1,500 – $2,800 |
| Insulation removal + replacement (fiberglass) | $2,200 – $3,800 |
| Spray foam (open-cell, roof deck application) | $2,800 – $5,500+ |
| Radiant barrier addition (attic floor or roof deck) | $700 – $1,500 |
These are Leander-market ranges based on conditions we see regularly – they are not national averages pulled from a database. Your written price will reflect your specific home. Under Haven Standard Clause 1, that price is flat and written before anyone lifts a tool. Call (737) 252-7159 to schedule your assessment and get a written estimate at no cost.
Why the Order of Operations Matters Here
Air sealing is not an upsell at Envelope Insulation Co. It is a prerequisite. We will not blow insulation over an unsealed attic floor – not because it is policy, but because doing so produces a measurably worse result and we can prove it with a blower-door test before and after.
A blower-door test – a pressurization reading that shows, in one number, how much air your building envelope is losing – costs nothing to include when we assess your home. In practice, a Leander home built between 2005 and 2015 often reads between 3,500 and 5,500 CFM50 before any work is done. After thorough attic air sealing, that number typically drops 30-50%, and the insulation added on top of a sealed floor holds that improvement. Without sealing first, adding R-value alone might drop the number 10-15%. The difference shows up on your electric bill within one billing cycle in a Texas summer.
On every applicable job, you receive the before and after readings in writing, included in your documented photo record. You don’t have to trust the claim – you can read the number yourself.
The Documentation You Receive
Under the Haven Standard, every job closes with a package of documentation, not a handshake and a closed door:
- Written scope and price – delivered before any work starts, flat rate, no hourly add-ons
- Documented photo record – before and after photos of every relevant area, included on every visit
- Blower-door readings – before and after, on every applicable air-sealing job, in writing
- Written warranty – delivered before the job starts, not mailed to you three weeks later
- 365-Day Done Right Promise – if the work is not right, we return and make it right, no charge
If you ever need to reference what was done – for a home sale, an insurance claim, or a utility rebate application – that documentation exists and we can reproduce it. We’ve seen how often homeowners wish they had this when their home goes on the market and an inspector asks what insulation was installed and when.

What Our Customers Say
"Two other companies quoted to blow more insulation on top of what was there. These were the only ones who said the existing material had to come out first, and explained why."
- Clifford E."The winter gas bill dropped by about a third. They had estimated a quarter, so they under-promised."
- Genevieve R."Crawl space encapsulation done properly. Photographs of the vapour barrier at every seam, and the damp smell in the hallway is gone."
