Average Costs Of Insulation
Average costs - $350 - $825
The average cost to hire a local professional can vary widely depending on the work that needs to be performed, they region in which you are located and how fast you need the project completed. So choosing the right professional the first time is of the essence.
Hourly Rate - Some companies charge by the hour.
Flat Rate Per Job - Some companies charge a flat rate for the work they do.
Recognize that there are several variables in developing the price. These include:
- Time that it takes to complete the project.
- How many technicians are working on your project.
- Was it an after hours emergency
- With many more aspects that may add to the cost
Remember, the company quoting a low rate may not necessarily be the right company for you. Some companies may offer low hourly rates, but then charge additional "fees" to complete the job.
You may also need to consider that most companies charge a higher rate for overtime, weekends, holidays and emergency calls.
The best rule of hand is to get an itemized estimate so you know exactly what is expected from the local company.
Determining The Cost Of Insulation
What kind of insulation is being installed? This will vary widely in the total cost of the installation. Remember! Cheaper is not always better.
What are the total square feet/area being installed? You want to cover as much area as possible
What is the labor to install the insulation. Hiring a professional insulation contractor will also provide you peace of mind knowing the job is done right the first time.
Different Types Of Insulation
Batt And Roll Insulation
Blanket insulation -- the most common and widely available type of insulation -- comes in the form of batts or rolls. It consists of flexible fibers, most commonly fiberglass. You also can find batts and rolls made from mineral (rock and slag) wool, plastic fibers, and natural fibers, such as cotton and sheep's wool. Learn more about these insulation materials.
Concrete Block Insulation
Concrete blocks are used to build foundations and walls, and there are several ways to insulate them. If the cores aren’t filled with steel and concrete for structural reasons, they can be filled with insulation.
Foam Board Insulation
Foam boards -- rigid panels of insulation - Provide good thermal resistance, and reduce heat conduction through structural elements, like wood and steel studs.
Radiant barriers work by reflecting radiant heat away from the living space. Radiant barriers are installed in homes -- usually in attics -- primarily to reduce summer heat gain, which helps lower cooling costs.
Fiber Board Insulation
Fiber board insulation consists of either fiberglass or mineral wool material and is primarily used for insulating air ducts in homes. It is also used when there's a need for insulation that can withstand high temperatures.
Spray Foamed Insulation
Spray foam insulation materials can be sprayed, foamed-in-place, injected, or poured. Some installations can have twice the R-value per inch of traditional batt insulation.
Insulated panels are prefabricated insulated structural elements for use in building walls, ceilings, floors, and roofs.
Loose Fill Blown-In Insulation
Loose-fill insulation consists of small particles of fiber, foam, or other materials. These small particles form an insulation material that can conform to any space without disturbing structures or finishes. This ability to conform makes loose-fill insulation well suited for retrofits and locations where it would be difficult to install other types of insulation.
- Blown-In Fiberglass Insulation
Fiberglass insulation gains its insulating power by trapping air inside of the billions of tiny glass fibers.The air gets trapped inside air pockets and actually slows the transfer of heat through the space.
- Blown-In Cellulose Insulation
In contrast to fiberglass insulation, cellulose insulation does not trap air in between it's fibers to control heat. By nature, the cells inside the cellulose insulation have their own insulating power.
An insulating material’s resistance to conductive heat flow is measured or rated in terms of its thermal resistance or R-value -- the higher the R-value, the greater the insulating effectiveness. The R-value depends on the type of insulation, its thickness, and its density. When calculating the R-value of a multilayered installation, add the R-values of the individual layers. Installing more insulation in your home increases the R-value and the resistance to heat flow. To determine how much insulation you need for your climate, use an insulation calculator or consult a local insulation contractor.
The effectiveness of an insulation material’s resistance to heat flow also depends on how and where the insulation is installed. For example, insulation that is compressed will not provide its full rated R-value. The overall R-value of a wall or ceiling will be somewhat different from the R-value of the insulation itself because heat flows more readily through studs, joists, and other building materials, in a phenomenon known as thermal bridging. In addition, insulation that fills building cavities densely enough to reduce airflow can also reduce convective heat loss.
The R-value for different types of insulation varies depending on the brand, how it was installed, and the region of the country you live in but here are some general comparisons.
Insulation Type: R-Value per Inch:
- Fiberglass (loose) 2 – 3
- Fiberglass (batts) 3 – 4
- Cellulose (loose) 3 – 4
- Stone Wool (loose) 2 – 3.5
- Stone Wool (batts) 3.5 – 4
- Cotton (batts) 3 – 4
- Cementitious (foam) 2 – 4
- Polyicynene (foam) 3.5 – 4.5
- Phenolic (foam) 4.5 – 8
- Polyisocyanurate (foam) 5.5 – 8
- Polyurethane (foam) 5.5 – 8
How Much Insulation?
The amount of insulation recommended for your home is dependent on where you live, but here are some general guidelines:
Houses in a cold climate should have a minimum of R-49 in the attic, which is equivalent to approximately 16″ of insulation. Warmer climates only require an R-38 or higher, or about 12″.
While wall insulation is limited by its width, different materials provide higher or lower R-values. Fiberglass batts for standard and are available in low, medium, and high density products that range from R-11 to R-15. Sprayed foam insulation in the same wall cavity can range from an R-14 to an R-28 depending on the product that is used.
While there are additional considerations—such as venting and moisture—to take into account when you insulate under floors, the standard recommendation of R-25 rating in cold climates and an R-11 in warmer parts of the country.
Tips & Advice
Ask For The License - Ask for all local and state business licenses.
Proof Of Insurance- For your own protection, check proof of both workman's compensation and liability Insurance.
Business Stability- Find out how long the company has been in business.
Check Online Reviews - You're probably not the first person in town looking for their services. Rely on the internet to get reviews written by people in your community.
References - Expect any top-notch company to be able to provide you with references upon request. Once you have these names, contact the clients to get information about the quality service. When you call, ask questions about the work, timeliness, cost and whether the clients would use the company again for future work.
24-hour Emergency Service - Make sure your local company offers emergency 24 hour service. If something goes wrong, it's good to know that you will not have to wait days for them to come out and fix it.
Over The Phone Pricing - Honest estimates simply cannot be given over the phone - especially if you aren't talking with an actual technician when you call.
Free Estimates - Most companies offer free estimates. This is important because they can provide you with the costs upfront, so that you are not shocked with a bill after the services are completed.
Safety Record - Safety can be a significant factor, so ask the company about their safety records to ensure that any service professional you hire has a satisfactory safety record. You want a company that doesn’t have a high incidence of on-the-job mishaps or injuries.
Satisfaction Guarantee - Choosing a company that offers a satisfaction guarantee will ensure that they will get the job done right the first time and will save you money and frustration in the long run.
Cleanup - The mess left behind after a project can be major. Ask what cleanup work the company includes with it's services.
