What our customers are saying

Two Brothers Insulation (Joe and Nado) are the real deal. They worked with me to insulate my house in Battle Ground area. The insulation job was pretty custom which included a custom hydronic floor heat insulation and sound-proofing. They were priced fairly, were able to get all of the best materials, were very honest and hard-working, and did a fantastic job! Plus, they are really nice guys. If you are thinking about insulation or about ways to improve your home's energy efficiency, don't hesitate to give these guys a call.

-J. Forrester, Battle Ground

Our family is currently conducting a whole house remodel. We have been dealing with a host of contractors for trade work with varied results, good, bad and mediocre. After seeking quotes from many firms, Two Brothers Insulation was our choice to install the insulation in both a sizeable room addition as well as several portions of the existing structure. Nado and Joseph were very responsive with their site survey and submission of a competitive quote within two days of the request. They were not the cheapest (beware of the cheapest), but much more reasonable than the big box firms. Once the quote was accepted, the brothers were on-site the next day and completed the work on budget and ahead of schedule. While working with them, I learned that they also are experienced in installing all forms of home siding. Their demonstration of customer service and attention to detail on the insulation portion led me to request an additional quote from them for this portion of the project. Once again, their prices were very competitive, so we gave them notice to proceed. Two weeks later, my wife and I cannot be more pleased with the results. Don't let the fact that these brothers have a relatively new company. Their work ethic, attention to detail and overall quality of work would be hard to match regardless of the age, size or marketing ability of any of the larger companies. The house looks fantastic, and every item associated with the siding was completed without my asking. During the final walk through there was not one single item on the punch list. Bottom Line. I do not hand out five star ratings unless they are absolutely earned. These guys are the best. they are skilled in many trades (fencing, decking etc.) don't be afraid to ask them what they can do outside of insulation. I would not hesitate for a second in giving them my highest recommendation.

-B. Tammen, Ridgefield

Two Brothers Insulating did a great job on our pole barn. They are committed to doing things right and taking care of their customers! Their communication through the whole process was great. They came out and looked at the job, gave their recommendations and answered questions. Two bids were provided so we could choose which R-value made the most sense for our needs. They were on time, worked hard, and did a good job of cleaning up. These two young entrepreneurs were easy to work with, very polite and did an outstanding job. We are very happy customers.

-R. Chemarin, Ridgefield

These guys will do what it takes to get the job done to your satisfaction. They paid attention to the details that matter and made sure I was happy with their work. Even though we ran into some unforeseen circumstances, they handled it professionally and made everything right.

You won’t go wrong with these guys!

-J. Dold, Battle Ground

I called Two Brothers to bid the insulating of my garage addition ceiling. I liked the price and was able to schedule the work within a few days. The brothers set baffles, installed over a thousand square feet of R-30 high density, and covered everything with vapor barrier in one day. They worked together like a well oiled machine, and in their personable style, made sure I was happy with the job. When you hire Two Brothers Insulating, you get 2 brothers and not a crew of underpaid strangers.

Here’s what we’ve been working on

Blow-In Blanket

(New Construction Residences)

Blow in fiberglass insulation is a type of insulation that is sprayed into the cavities of exterior walls of a new construction building. It has several benefits over other types of insulation, such as:

- It provides a higher R-value per inch, which means it can achieve better thermal performance with less thickness. This can save space and reduce the cost of framing materials.

- It fills the gaps and cracks in the wall more effectively, creating a tighter air seal and preventing air infiltration and heat loss. This can improve the energy efficiency and comfort of the building.

- It is resistant to moisture, mold, fire, insects and rodents, which can protect the building from damage and health hazards. It also does not settle or sag over time, maintaining its effectiveness for longer.

- It is made from recycled glass and sand, which are abundant and renewable resources. It also reduces greenhouse gas emissions by saving energy and preventing waste. It is an environmentally friendly choice for insulation.

Blow in fiberglass insulation is a smart option for insulating exterior walls of a new construction building. It can provide superior performance, durability and sustainability compared to other types of insulation.


Pole Barns

Fiberglass insulation is a cost-effective and energy-efficient way to improve the comfort and performance of a pole barn. Pole barns are typically used for agricultural, commercial, or residential purposes, and they can benefit from fiberglass insulation in several ways. 

First, fiberglass insulation can reduce heat loss or gain through the walls and roof of the pole barn, which can lower the heating and cooling costs and extend the lifespan of the building. Fiberglass insulation can also prevent condensation and moisture problems that can damage the structure and its contents. 

Second, fiberglass insulation can improve the acoustics and noise control of the pole barn, which can be important for some applications. Fiberglass insulation can absorb sound waves and reduce the transmission of noise from outside or inside the pole barn. This can create a more comfortable and productive environment for the occupants and their activities.

Third, fiberglass insulation can enhance the fire safety and fire resistance of the pole barn, which can protect the building and its contents from potential hazards. Fiberglass insulation is non-combustible and does not emit toxic fumes when exposed to fire. Fiberglass insulation can also slow down the spread of fire and provide more time for evacuation and firefighting.

In conclusion, fiberglass insulation is a smart choice for pole barn owners who want to improve the quality and value of their buildings. Fiberglass insulation can provide thermal, moisture, acoustic, and fire benefits that can make a pole barn more comfortable, efficient, durable, and safe.


Vaulted Ceilings

Fiberglass insulation is a common and effective way to improve the thermal performance of a vaulted ceiling. A vaulted ceiling creates a spacious and airy feeling in a room, but it can also result in higher heating and cooling costs due to the increased volume of air. By installing fiberglass insulation between the rafters, you can reduce heat loss in winter and heat gain in summer, saving energy and money. Fiberglass insulation also helps to prevent condensation and moisture problems that can damage the roof structure and cause mold growth. Fiberglass insulation is easy to install, fire-resistant, and available in different R-values to suit your climate and building code requirements.



Airsealing and insulating your attic can have many benefits for your home and your wallet. Airsealing prevents warm air from escaping through gaps and cracks in the attic floor, while insulating reduces heat transfer through the roof. Together, these measures can help you save energy and money on heating and cooling bills, as well as improve your indoor comfort and air quality. Here are some of the benefits of airsealing and insulating your attic:


- Lower energy bills: By reducing the amount of heat that escapes or enters your home through the attic, you can reduce the need for heating and cooling systems to work harder and longer. This can lower your energy consumption and costs by up to 20%.

- Improved comfort: Airsealing and insulating your attic can help maintain a more consistent temperature throughout your home, especially in rooms directly below the attic. This can prevent cold drafts in winter and hot spots in summer, making your home more comfortable year-round.

- Better air quality: Airsealing and insulating your attic can also prevent moisture, dust, pollen, pests, and other pollutants from entering your home through the attic. This can improve the air quality in your home and reduce the risk of mold, allergies, asthma, and respiratory problems.

- Increased home value: Airsealing and insulating your attic can also increase the value of your home by making it more energy-efficient, comfortable, and healthy. This can attract more buyers and increase your resale price.

As you can see, airsealing and insulating your attic is a smart investment that can pay off in many ways. If you are interested in improving your home's performance and comfort, contact us today to get started.


Radiant Systems and Crawl Spaces

A radiant barrier is a thin layer of reflective material that blocks radiant heat transfer from the sun. Installing a radiant barrier with your crawlspace insulation can have several benefits for your home and your energy bills. Here are some of them:

- A radiant barrier can reduce the heat gain in your crawlspace, which can lower the temperature and humidity levels in this area. This can prevent moisture problems, mold growth, and wood rot that can damage your home's structure and air quality.

- A radiant barrier can also reduce the heat loss from your crawlspace, which can improve the thermal performance of your insulation. This can help you maintain a comfortable indoor temperature and reduce your heating and cooling costs.

- A radiant barrier can also protect your insulation from dust, dirt, and pests that can reduce its effectiveness and durability. By keeping your insulation clean and intact, you can extend its lifespan and avoid frequent replacements.

Installing a radiant barrier with your crawlspace insulation is a simple and cost-effective way to enhance your home's energy efficiency and comfort. You can choose from different types of radiant barriers, such as foil sheets, spray-on coatings, or laminated boards, depending on your preference and budget. You can enjoy the benefits of a radiant barrier for years to come.


Dense Pack Retrofit Wall Insulation

Dense packing insulation is a technique that involves filling the cavities of an exterior wall with dense cellulose or fiberglass material. This can provide several benefits for older homes that may have inadequate or deteriorated insulation. Some of the benefits are:

- Improved thermal performance: Dense packing insulation can reduce heat loss and gain through the wall, resulting in lower energy bills and more comfortable indoor temperatures.

- Enhanced air sealing: Dense packing insulation can also block air leaks and drafts that may compromise the efficiency and comfort of the home. This can improve indoor air quality and reduce moisture problems.

- Reduced noise transmission: Dense packing insulation can act as a sound barrier, reducing the noise from outside sources such as traffic, neighbors, or weather. This can create a quieter and more peaceful living environment.

- Preserved historical integrity: Dense packing insulation can be installed without altering the appearance or structure of the exterior wall, preserving the historical and aesthetic value of the home. This can also avoid potential damage or disruption to the existing finishes and features of the home.


Blower Door Testing

A red blower door and a thermal imager are two tools that can help you identify and fix the air leaks in your home. A blower door is a device that creates a pressure difference between the inside and outside of your home, forcing air to flow through any gaps or cracks. A thermal imager is a camera that shows the temperature of different surfaces, revealing where heat is escaping or entering your home. By using these tools together, you can get a comprehensive picture of your home's energy efficiency and comfort level.

The benefits of using a red blower door and a thermal imager are:

- You can save money on your heating and cooling bills by reducing the amount of air that leaks in or out of your home.

- You can improve your indoor air quality by preventing dust, allergens, and pollutants from entering your home through leaks.

- You can increase your home's durability by preventing moisture and mold problems caused by air leaks.

- You can enhance your home's safety by detecting any gas leaks or carbon monoxide issues caused by air leaks.

We have the experience and expertise to help you find and fix the air leaks in your home, and make it more energy efficient, comfortable, and healthy. Contact us today for a free estimate!


Finish the job with a Re-Side

If you are looking for a way to improve the energy efficiency and curb appeal of your home, you may want to consider residing your home with hardie siding after densepacking insulation into your exterior walls from the outside. This is a service that Two Brothers Insulating, LLC can provide for you with professionalism and quality.

Densepacking insulation is a process of filling the cavities between your wall studs with dense cellulose or fiberglass material, creating a tight seal that prevents air leakage and heat loss. This can lower your heating and cooling bills, reduce noise, and increase fire resistance. Densepacking insulation can be done from the outside by removing a strip of your existing siding, drilling holes in the sheathing, and blowing in the insulation. Then, the holes are patched and the siding is replaced.

However, if your siding is old, damaged, or unattractive, you may want to take this opportunity to upgrade to hardie siding. Hardie siding is a durable and beautiful fiber cement product that can withstand harsh weather conditions, resist pests and fire, and last for decades. Hardie siding comes in a variety of colors and styles to suit your taste and complement your home's architecture. By residing your home with hardie siding after densepacking insulation, you can enhance the appearance and value of your home while saving money and energy.
