Expert Insulation Services for San Antonio

 Whether you're building a new home, upgrading an existing property, or insulating a commercial building, proper insulation is one of the smartest investments you can make.


We've been serving homeowners, builders, and businesses throughout the San Antonio area for over 14 years. We provide professional removal and installation of blown-in, batt, and spray foam insulation for projects of all sizes—from single-family homes to large commercial buildings.


Our promise is simple: Quality materials, expert installation, competitive pricing, and results you can measure on your energy bills.

WHY INSULATION MATTERS

Lower Energy Bills

Proper insulation can reduce your heating and cooling costs by 20-50%. In San Antonio's climate, where air conditioning runs 8-9 months per year, that translates to $500-$1,500+ in annual savings for the average home. Over 2-4 years, quality insulation more than pays for itself—and keeps saving you money every month after that.

Year-Round Comfort

Insulation doesn't just save money—it makes your space more comfortable.


In summer: Keeps heat out, reduces AC workload, eliminates hot spots

In winter: Retains warmth, prevents drafts, maintains consistent temperatures

Properly insulated buildings stay comfortable in every room, all year long.

Protect Your Investment

Buildings with inadequate insulation experience:

  • Higher utility costs
  • Overworked HVAC systems (leading to early failure)
  • Temperature fluctuations that stress materials
  • Moisture issues that can lead to mold


Quality insulation protects your property and extends the life of your heating and cooling systems.

Frequently Asked Questions

Please reach us at hello@sanantonioinsulation.com if you cannot find an answer to your question.

The best type of insulation for your home depends on several factors such as the size of your space, your budget, and your insulation needs. Our team can help you determine the best insulation option for your home.


Insulation can last for many years if it is installed properly and maintained. However, the lifespan of insulation can also depend on factors such as moisture, pests, and wear and tear.


Yes, insulation can help reduce noise pollution and improve soundproofing in your home or business.


Yes. The U.S. Department of Energy estimates that proper insulation can reduce heating and cooling costs by 20-50%. In San Antonio's climate, homeowners typically see at least $500-$1,500 in annual savings. 


The Department of Energy recommends R-30 to R-49 for attics in our climate zone. We typically recommend R-32 to R-38 as the sweet spot for cost-effectiveness and performance. 


Absolutely. Blown-in insulation is ideal for adding insulation to existing attics without removing the roof or ceiling. We also retrofit walls when possible. 


Yes. Spray foam insulation is excellent for metal buildings, shops, and barns. It seals gaps, prevents condensation, and creates a comfortable climate-controlled space. 


Most residential attic insulation projects are completed in +/- 4 hours. Larger projects or spray foam applications may take 1-2 days. We'll provide a timeline with your estimate.
