Our Insulation Services
We offer a wide range of home insulation solutions tailored to meet your needs:
Insulation Installation
We install top-quality insulation materials in attics, basements, crawl spaces, garages, and walls—helping you stay comfortable year-round while reducing heating and cooling costs.
Air Sealing
Air leaks around windows, doors, and other openings reduce the effectiveness of your insulation. Our air sealing service closes those gaps to prevent drafts and improve energy performance.
Crawl Space Insulation
Insulating and sealing crawl spaces reduces heat loss, improves air quality, and prevents issues like moisture buildup and cold floors.
Spray Foam Insulation
Spray foam offers excellent insulation and air sealing in one step. It's ideal for hard-to-reach spaces like attics, basements, and crawl spaces, and helps maintain consistent indoor temperatures.
Attic Insulation
Upgrading your attic insulation is one of the most effective ways to improve comfort and reduce energy waste. We assess and install insulation that meets modern efficiency standards.
Basement Insulation
Cold, uninsulated basements can make your entire home harder to heat. We insulate basement walls and rim joists to keep heat in and moisture out.
Garage Insulation
If your garage shares walls or ceilings with your living space, insulating it can reduce temperature swings and improve overall home comfort.
Retrofit Insulation
Older homes often lack sufficient insulation. We upgrade outdated materials with modern insulation that brings your home up to today’s energy standards.
Insulation Removal
Old or damaged insulation can impact indoor air quality and energy performance. We safely remove existing insulation and prepare your space for upgrades.
Why You Need Insulation Services
Insulation plays a critical role in your home’s overall energy performance. It’s not just about comfort—it’s about protecting your home systems and reducing unnecessary energy use.
Here’s why insulation matters:
- Reduce Energy Waste – Poor insulation allows heated and cooled air to escape, forcing your HVAC system to work harder than it should.
- Extend HVAC Lifespan – By maintaining stable indoor temperatures, insulation takes pressure off your furnace and air conditioner, helping them last longer with fewer repairs.
- Lower Utility Bills – Better insulation means your home stays at a consistent temperature using less energy—saving you money each month.
- Improve Indoor Comfort – Eliminate hot and cold spots, drafts, and inconsistent temperatures throughout your home.
- Protect Air Quality & Moisture Control – When combined with air sealing, insulation helps keep out dust, allergens, and moisture that can lead to mold or poor air quality.
- Reduce Strain on the Grid – Utilities offer rebates for insulation upgrades because energy-efficient homes help reduce the demand on power grids. When homes waste less energy, utilities don’t have to generate as much—protecting resources and keeping energy costs stable for everyone.
At REenergizeCO, we make insulation upgrades simple and accessible—helping you take advantage of rebate programs and long-term energy savings, all while improving the comfort and performance of your home.

Commonly Asked Questions About Home Insulation
What is Home Insulation?
Insulation is a term used to describe a wide range of products that reduce heat loss or heat gain by providing a barrier between areas that have a significant difference in temperature. An example of this could be a warm winter coat which insulates the human body from the cold temperature around it or blanket which someone can use to keep them warm on a cold winter night. Home insulation protects important areas of your home such as your hot water pipes and your HVAC system from freezing in the winter and traps precious conditioned air to keep your house cool in the summer.
Common Types of Home Insulation Installation
There are many types of insulation, and they all have the benefits and drawbacks. The types of insulation found in homes across Colorado include:
Fiberglass Insulation
Fiberglass insulation happens to be the most common form of insulation used in homes. Fiberglass insulation minimizes heat transfer effectively because it is made with fine strands of glass that are woven into the insulation material. When installed properly and safely, fiberglass insulation can be very effective. It is non-flammable and has tremendous R-values. If you are seeking a relatively inexpensive form of insulation, fiberglass is the way to go. We encourage you to contact the home insulation experts at REenergizeCO so we can install your new insulation without a hitch.
Mineral Wool Insulation
Mineral wool can be referred to as a number of different products such as:
- Glass wool made with recycled glass
- Rock wool made from basalt
- Slag wool made from slag from steel mills (the most common form of mineral wool)
Mineral wool comes in the form of batts and loose-fill material. Most mineral wool is not fire resistant which can make it vulnerable in situations where intense heat is present. It is often used to supplement other forms of insulation and can be very effective for insulating larger areas of a Colorado home.
Cellulose Insulation
Cellulose insulation happens to be one of the most eco-friendly forms of insulation on the market today. It is made from mostly recycled materials and comes in a loose form. Recent studies on insulations have revealed that cellulose insulation may, in fact, be effective in minimizing fire damage. Because cellulose insulation is so compact, it contains little to no oxygen within it, which helps it contain fires. Cellulose insulation is great for retrofitting areas of your home and is an excellent supplementary insulation to fiberglass, spray foam, and mineral wool.
Polyurethane Foam Insulation (Spray Foam)
Polyurethane foam or spray foam insulation is a fantastic insulator with tremendous R-value. Acting as both an air barrier and moisture barrier, there is no better product on the market that will keep your home comfortable year round. It is created on site and sprayed onto the desired area. From there, it expands to fill any crack and crevice it encounters. Spray foam in impermeable to water as well, making it odorless and mold resistant if ever encountered by excess water.
What is the best type of insulation?
Every type of insulation material (foam, cellulose, and fiberglass) has inherent benefits and drawbacks, and each performs differently depending on the application. At REenergizeCO, we don’t specialize in one insulation. We are experienced Denver insulation contractors.
What does retrofit mean?
Retrofitting a home’s insulation simply means upgrading a home’s insulation by adding, replacing, or removing insulation. During a retrofit, we will remove small sections of siding and drill small holes into the walls. Next, we insert a small hose into the hole and fill the space. This will result in a nice insulated wall cavity.
What insulation is eco-friendly?
Certain types of insulation are more eco-friendly than others. For example, our loose-fill insulation made from cellulose, used in homes all over Colorado, is mostly recycled and offers excellent energy savings.
How can I know what the R-value of my insulation is?
The R-value of your insulation will be determined by what type of insulation you are using. Insulations come with a predetermined R-value, so be sure to ask the experts at REenergizeCO what the recommended R-values are for your project. It shouldn’t be overlooked that insulation will decrease in R-value over time as the product grows older and settles within its space.
Will insulating certain areas of my home result in energy savings?
Insulating certain areas of your home may lead to some energy savings, but to get the most out your insulation, you should insulate your entire home. Visit our pricing page to learn more.
Can insulation reduce sound?
In fact, insulation installation can reduce unwanted noise and provide soundproofing, creating a quieter, more comfortable working environment in your home. Insulation can effectively reduce noise that flows through interior and exterior walls, as well as through floors and ceilings.
Improve Comfort and Cut Energy Costs with an Insulation Assessment
The best way to find out what your home needs is to start with a Home Energy Audit. We evaluate your insulation levels, locate problem areas, and create a tailored plan to boost your home’s efficiency and comfort.

Before we dive into the benefits of Home Insulation, let's first talk about what Home Insulation is and what purpose it serves. The housing enclosure is what separates the controlled environment (inside) from the uncontrolled environment (outside) those walls that surround you and that roof thing that goes over your head. The fine layer in between the inside and outside is where insulation lives.
