Trusted Attic Insulation Nationwide
Attic insulation is the single most effective upgrade for cutting heating and cooling costs, and most homes across the United States are under-insulated by current Department of Energy standards. Alden Attic Insulation has been installing and removing attic insulation since 2002 as part of the Garrison Partners family, with every job backed by a written 365-day guarantee. We answer the phone with a live person 24/7, and our background-checked, uniformed technicians arrive inside the scheduled window. Call (254) 272-5876 for a free estimate with the written price in your hand before any work begins.
Insulation Contractors
Insulation Contractors are the licensed professionals who assess, install, and remove attic insulation, and hiring the right one determines whether your home stays comfortable and your energy bills stay low. Most attic insulation projects run $1,200 to $3,400 depending on square footage, current R-value, and the material you choose. Alden Attic Insulation sends a background-checked technician to measure your attic, calculate current R-value, and hand you a written price before a single tool comes off the truck. We install products from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber, so you can research exactly what goes into your attic before saying yes. Our crews operate under The Garrison Standard: written prices, written guarantees, and a 365-Day Done Right Promise on every job.
Assessment and Written Pricing
We do not quote over the phone and revise at the door. A technician inspects your attic, measures square footage and existing R-value, checks for air leaks, and then writes the price down. The number you approve is the number on the invoice.
Installation Without Surprises
Our crew arrives in uniform inside the promised window, lays down protection, and installs to manufacturer specification. You get a written guarantee for 365 days, and if anything fails in that window, we return at no charge.
Attic Ventilation
Attic Ventilation is the system of intake and exhaust vents that moves hot, moist air out of your attic, and without it your insulation underperforms and your roof decking can rot from trapped moisture. Most attic ventilation work runs $300 to $900 for typical installations, depending on the number and type of vents needed. Alden Attic Insulation checks ventilation as part of every attic insulation project because insulation and airflow work together, and poor ventilation is a common reason insulation fails early. Following an Attic Insulation Maintenance Checklist for Los Angeles Homeowners helps catch these issues before they spread. We install and balance intake and exhaust vents so the attic stays dry and the insulation holds its R-value year after year. Our work carries the 365-Day Done Right Promise: if it fails in that time, we come back at no charge.
Common Ventilation Problems
We regularly find attics where exhaust vents exist but intake vents are missing, which starves the airflow and pulls conditioned air from the living space. Another frequent issue is bathroom fans venting into the attic instead of outside, pumping moisture directly into the insulation.
How Alden Addresses Airflow
We calculate the right ratio of intake to exhaust for your attic and install matched venting. That means your insulation stays dry, your roof decking lasts, and your cooling bills drop in summer.
Radiant Barrier
Radiant Barrier is a reflective material installed in the attic that reduces heat transfer from the roof into the living space, and it’s most effective in hot climates with long cooling seasons. Radiant barrier installation typically runs $800 to $2,000 depending on attic size and whether it is stapled to rafters or laid over existing insulation. Alden Attic Insulation installs radiant barrier as a complement to insulation, not a replacement, because it reflects radiant heat while insulation slows conductive heat, and the two work on different principles. We use products from brands like Icynene and Demilec when a project calls for their materials, and every installation includes a written price before work starts. The 365-Day Done Right Promise applies here the same as anywhere: if it fails, we return free.
What Radiant Barrier Does Not Do
It is not insulation and it does not have an R-value. Homes in cold climates see little benefit, and a radiant barrier installed poorly can trap moisture against the roof deck.
When It Makes Sense
In hot regions with long summers, a radiant barrier can cut attic temperatures by 20 to 30 degrees and reduce cooling costs meaningfully. We tell you honestly whether it is worth the money for your house before you commit.
Attic Cleaning Services
Attic Cleaning Services remove old debris, dust, animal droppings, and contaminants from your attic, and you need them before installing new insulation or after a rodent or pest problem. Attic cleaning typically runs $500 to $1,800 depending on attic size, amount of debris, and whether contaminants like droppings are present. Alden Attic Insulation cleans attics with the same discipline as insulation work: written price before work starts, uniformed technicians, and a written guarantee. We remove contaminated insulation, sanitize surfaces, and prepare the space for fresh blown-in or batt insulation. Our crews operate under The Garrison Standard, and calls are answered by a live person 24/7 at (254) 272-5876.
Before New Insulation
You should not blow new insulation over old, contaminated material. We remove what is there, clean the decking, and air seal before the new material goes in so the R-value performs as rated.

After Pests or Rodents
Rodent droppings and urine are a health concern and a smell problem, and leftover nesting material will keep attracting the next infestation. We remove the contaminated material and sanitize so the space is safe to re-insulate.

Attic Mold Removal
Attic Mold Removal is the process of eliminating mold growth from attic surfaces and addressing the moisture source that feeds it, because mold in the attic usually points to a ventilation or roof problem that insulation alone cannot fix. Attic mold removal typically runs $1,000 to $3,500 depending on the affected area and whether insulation must be removed along with the mold. Alden Attic Insulation removes contaminated insulation, treats affected surfaces, and restores ventilation so the mold does not return. Mold in an attic is a health and structure concern, and we recommend a trained professional handle it rather than a homeowner attempting DIY removal. Our 365-Day Done Right Promise covers the work in writing, and our technicians arrive background-checked and in uniform.
The Moisture Source Comes First
Removing mold without fixing the moisture source is a waste of money. We trace the problem back to the cause, which is usually inadequate attic ventilation or a leaking roof, before we clean and restore.
Insulation Replacement After Mold
Moldy insulation cannot be cleaned; it must be removed and replaced. We pull the contaminated material, clean the space, and install new insulation from brands like Knauf, Rockwool, or CertainTeed.
Attic Insulation Removal
Attic Insulation Removal is the process of pulling out old, damaged, or contaminated insulation so a clean foundation remains for new material, and you need it when insulation is water-damaged, pest-infested, moldy, or compacted past its useful life. Attic insulation removal typically runs $1,000 to $2,500 depending on attic size, insulation type, and how much must be bagged and hauled out. Alden Attic Insulation removes fiberglass, cellulose, and mineral wool insulation with industrial vacuums and hand tools, then disposes of the material properly. We check the attic deck for damage, air seal where needed, and prepare the space for fresh blown-in insulation. The written price is in your hand before we start, and the work carries the 365-Day Done Right Promise.
When Removal Is Necessary
Water from a roof leak compresses insulation and destroys its R-value. Rodent infestations leave droppings and urine inside the material, and old insulation can become so compacted it no longer insulates at all.
What Happens After Removal
Once the attic is empty, we inspect the decking and wiring, air seal the floor, and install fresh material from brands like Owens Corning, GreenFiber, or Rockwool. The result is a clean attic with insulation that performs at its rated R-value.
Brands We Service
We work with a focused list of manufacturers, not whatever is cheapest at the supply house. Knauf and Rockwool produce mineral wool insulation we install regularly, and both handle moisture better than fiberglass, which matters in humid climates. CertainTeed fiberglass and Icynene foam are also part of our install lineup, each with specific strengths for different attic conditions.
Because we install these brands every week, our crews know their rated R-values, proper installation depths, and how they perform in real attics, not just on the data sheet. Whether you have an existing Knauf, Rockwool, or CertainTeed installation we are removing, or you are choosing fresh material for the first time, we can help.
Signs You Need a Pro Right Now
- Your energy bills climbed without a rate change. If heating and cooling costs are rising but your usage habits have not changed, the attic insulation may have settled, gotten wet, or been displaced. A pro can measure the current R-value and tell you what you are missing.
- You can see the attic floor joists through the insulation. Most homes need 13 to 18 inches of blown-in insulation depending on the material and your climate zone. If joists are visible, the insulation is below recommended depth and underperforming.
- Rooms over the garage or upper floor are hard to keep comfortable. Temperature differences between floors often trace back to uneven attic insulation coverage. This is also common over additions where builders skimped on insulation.
- You found rodent droppings or nesting material in the attic. Pests contaminate insulation and compress it into useless mats. Removal and replacement is the only fix, and the longer it waits, the more the material degrades.
- You see frost, water stains, or mold on attic surfaces. Moisture in the attic means a ventilation or roof problem is already damaging your insulation and decking. Mold and rot spread quietly, and the fix gets more expensive the longer it sits.
Our Process, Step by Step

How Much Does Attic Insulation Cost?
A typical attic insulation project runs $1,200 to $3,400 depending on square footage, current R-value, and the material you choose, so review Attic Insulation pricing to understand what drives your estimate. Blown-in fiberglass or cellulose for a standard 1,500 square foot attic usually lands in the $1,500 to $2,500 range, while spray foam or mineral wool pushes the number higher. Attic insulation removal runs $1,000 to $2,500, attic cleaning services $500 to $1,800, radiant barrier $800 to $2,000, and attic mold removal $1,000 to $3,500 depending on severity.
The biggest cost drivers are attic size, how much old material must come out first, and your target R-value. The way to avoid overpaying is to get the written price before work starts and to compare apples to apples: same material, same R-value, same scope. A free estimate from Alden includes the inspection, the measurements, and a written price you can hold in your hand. Call (254) 272-5876 and you will know exactly what the job costs before you decide.

Frequently Asked Questions About Attic Insulation
Attic insulation is material installed in the attic floor or roofline that slows heat transfer between your living space and the outdoors. It is measured in R-value, which rates resistance to heat flow, and most homes need R-38 to R-60 depending on climate. Alden installs blown-in fiberglass, cellulose, and mineral wool from brands like Owens Corning, Knauf, and CertainTeed.
Most attic insulation jobs are completed in one day, including the inspection, removal of old material if needed, and installation of the new insulation.
