Home Insulation Services

Proper insulation in key areas of your home can significantly improve temperature control and comfort. By insulating these vulnerable spots, you can enhance energy efficiency:

  • Attics: Insulating an attic will prevent heat loss and overhead drafts.
  • Walls: Ensure thermal efficiency with wall insulation, which is particularly important in older homes or properties.
  • Crawl spaces: Insulation in crawl spaces protects against moisture while preventing mold or mildew growth.
  • Basements: An insulated basement is less drafty and damp.

ThermaSeal/Lakeside Insulation’s process starts with a thorough assessment to determine your needs, followed by material recommendations. After professional installation, we conduct extensive quality checks.

Different Types of Insulation We Install

We offer a variety of insulation products to cover residential and commercial needs:

  • Fiberglass insulation: This affordable, fire-resistant option is ideal for attics and walls.
  • Spray foam insulation: A superior sealant, spray foam is a strong moisture barrier that’s applied in hard-to-reach areas like crawl spaces.
  • Cellulose insulation: Cellulose is an eco-friendly choice for walls and attics with excellent soundproofing properties.
  • Rigid foam insulation: Rigid foam has a high R-value, which measures how effectively insulation resists the flow of heat into and out of a space.
  • Blown-in insulation: This fast and efficient solution is applied by distributing small particles into existing structures.

Choosing the right insulation for your project begins with a professional consultation. Based on your property’s location, age and needs, we’ll recommend the best insulation type with the appropriate R-value.
