San Antonio’s trusted attic insulation provider since 2006

20 Years of Excellence, One Attic at a Time

A lot has changed in 20 years, but our commitment to doing the job right hasn't. For two decades, we have helped thousands of homeowners slash their utility bills and protect their HVAC systems from the brutal Texas heat. We’ve built our business on the belief that a "ladder peek" isn't enough—that’s why we still crawl every attic end-to-end, just as we did on day one. Experience matters when it comes to your home’s efficiency. Trust the team that San Antonio has relied on for 20 years.

Expert Attic Insulation Services

Why Blown Insulation?

Installing a thick, seamless layer of premium blown-in insulation creates a "Heat Shield" for your home. While traditional fiberglass batts leave gaps, blown insulation solves this.

• Seamless Thermal Protection

Our insulation flows into every nook and cranny, sealing the hidden gaps that traditional rolls simply can’t. 

• Maximum HVAC Efficiency

Stop fighting 150°F attic temperatures. By blocking the heat at the source, your AC can finally cycle off, lowering your monthly bills and extending the life of your equipment.

• The Texas-Proof Barrier

Built for the brutal summer, but designed for the "Big Freeze." This high-density layer acts as a thermal blanket during winter, keeping your expensive heated air exactly where it belongs—inside.

Stop letting your attic dictate your comfort. We provide the coverage necessary to maintain a steady, perfect climate in every room of your home, 365 days a year.

Utility Savings

Lower Your Bills, Starting Today

It’s simple math: when your HVAC system runs less, you pay less. In Texas, heating and cooling account for 50–60% of your total utility costs. Because a properly insulated attic is the #1 way to reduce that strain, CPS Energy offers significant rebates to help homeowners upgrade. Many of our customers see their utility costs drop by up to 30% just by reaching the proper insulation depth. Don't leave money on the table—ask us how to qualify for CPS rebates and start saving immediately.

Quality Attic Insulation Process

The Inspection


A proper insulation plan can’t be made from the top of a ladder. While other companies might just "peek" into your attic, we perform a comprehensive, end-to-end crawl. We inspect every square foot of the space to measure your current insulation levels and calculate exactly what you need to meet modern efficiency standards. Along the way, we look for hidden issues that may need attention. If we find anything concerning, we document it with photos so we can discuss the best solution with you before work begins.

Things we look for

Insulation is the final step, but it shouldn't be the first. We use our inspection to identify hidden issues that could cost you money or compromise your safety later. We thoroughly check for:

• Air Duct Integrity: Locating holes or leaks that waste your heated and cooled air.

• System Safety: Identifying visible electrical hazards or plumbing leaks.

• Pest & Debris Alerts: Spotting signs of rodent damage or old debris that needs removal.

We believe in doing the job right the first time. If we find an issue, we’ll alert you immediately so it can be resolved before it’s covered by an over foot of insulation.

Plan of action

After the inspection, we will discuss what we found and provide a plan moving forward. We leave you with an exact cost and scope of work. If your home qualifies for a CPS rebate, we will explain the process and handle the paperwork for you.

We are a no pressure company. You schedule the work when you’re ready.

The Job

To keep your home comfortable, our day typically begins early in the summer —finishing most installations before the midday heat. We treat your home as if it were our own, starting every job by laying protective tarps over the work area when inside the house. After prepping the attic by performing any necessary ductwork or other repairs, we install attic rulers to guarantee a precise, uniform insulation depth. When installing the new insulation, we start in the furthest corner and slowly working our way back out of the attic. This ensures every corner is covered, typically completing the entire process in just a few hours.

Finishing Touches

Our job isn’t done until your home is as clean as we found it. Once the insulation is installed, we perform a thorough cleanup of all work areas. We then invite you to inspect the attic personally or review a digital gallery of photos we took during the process to ensure you're satisfied with the coverage. After answering any questions you may have, we provide a detailed invoice for your records. We collect payment—via cash, check, or major credit card—once you are 100% confident in our work.

Frequently Asked Questions

If you can see the ceiling joists in the attic, that’s the wood framing on the floor of the attic, then you are likely in need of insulation. Ideally, your attic insulation should be at least one foot deep. 


Most jobs can be done in 3-4 hours.  We will provide you with an approximate time when we see the house. 


Not for us. We have been at this for a long time and know how to be careful. We use tarps under our workspace and always vacuum when we’re done. 


For many CPS customers the answer is yes. It depends how much insulation you currently have. We can let you know for sure during the inspection. See our rebate tab for more information...


The cost depends generally on three factors. How much material we need, the square footage and how difficult the job is. At the end of the day we want your insulation to be over a foot deep. Since we have been doing this for many years, working in every neighborhood, we often can provide a rough estimate over the phone just by looking up some information on the house.


If your insulation is extremely poor, you will notice a big difference. Your air conditioner will run much less and your home will feel much more comfortable. It just depends on how much insulation you have in the attic currently. We will certainly be able to let you know how much of an impact our services will have when we see the attic.


Absolutely. A home with poor insulation will cause the air conditioner and heater to run much longer than it should. In the summer an AC may run non stop, at least during the day. Certainly an AC that is overworked will not last as long as it should and eventually require costly repairs.


No. We did years ago but fount that it had some significant downsides. See our blog for more info.

"Highly recommend Quality Insulation. Replaced the old gray insulation in the attic and could tell a difference immediately with the house being cooler and especially with CPS bill, as well as Patrick assisting with the CPS rebates to bring the cost way down. Working with Patrick was a great decision and his service and expertise is greatly appreciated as he's a wealth of information far beyond insulation. Thank you!"

"Quality Insulation did an amazing job in my attic. I could feel the difference immediately after they completed the work. Patrick is a true professional who went above and beyond to explain every step of the process; he even corrected some issues he saw with ducts and wiring before blowing in the insulation. Highly recommended!"

"I highly recommend Quality Insulation to anyone who is looking to upgrade their current attic insulation. Our home is 12 years old and was insulated at about half of what is currently recommended.  Patrick came in last week and totally inspected our current insulation levels, plumbing and ductwork. He gave us a fair bid (we've had this work done in a previous home) and completed the work today. He was on time, courteous, knowledgeable, and came highly recommended to us from a coworker. We are now better prepared for whatever winter and summer San Antonio has in store for us!"

"Called Quality Insulation and immediately received a call back from Patrick. He was able to meet me the same day to assess the needs and has a quote the same day.  We were able to schedule installation early the next week as he actually fit us in as he was going out of town. The work was completed as advertised in less than half a day.  He repaired a couple of vent items and reviewed the work with me. He was very professional and timely. I would recommend Quality Insulation."

"Contacted Patrick to get an estimate for insulation. After thoroughly looking at my attic he told me I didn’t need insulation. However he found a leak in my A/C system. He showed me the problem and then advised me on what needed to be done. I’m not someone that usually writes review but I’m making an exception in this case. I’ve dealt with many repair companies/ individuals. In my experience it’s rare to run across someone with the integrity, professionalism and genuine desire to help that Patrick demonstrated. Thank you, Patrick and God bless."
