We all know that insulation is a great way to reduce energy usage and save big on heating and cooling bills, but is the cost of installation worth the utility bill savings? If you are thinking about insulating your home, it is helpful to get an idea of how much the whole project will cost. Of course every project is different, but we’ve checked in with a lot of experts to see how much the average homeowner pays for insulation. Keep reading to find out everything you need to know about the price of insulation.
The Typical Price for Insulating a House
The national average for insulating a standard home is about $3,500 to $4,500, which is significantly cheaper than the costs associated with commercial insulation. However, this is just the average, so your project might be a little more or less. The typical low price for insulation is around $2,000, and it is fairly common for more expensive projects to cost around $6,000. There are a lot of things that can change your costs for insulation, so the rest of our guide will go into the details of what affects insulation prices.
The Price Per Square Foot for Different Types of Insulation
Of course, it is important to keep in mind that the above price is just the average cost for a typical house. Factors like where you live, how big your building is, and what type of insulation can all make your personal estimate go up or down. Insulation prices are usually calculated based on the square foot, and different insulation materials have different costs.
To get an accurate idea of how much your project will cost, pick your insulation type, as you can even go with insulation for metal buildings, measure the number of square feet needed and use this guide to calculate prices.
- Spray foam: This insulation is a type of sprayed-on foam that expands after being applied. It is usually $0.50 per square foot for open-cell foam or $1.00 per square foot for closed-cell foam.
- Fiberglass batts: Fiberglass batts are thick rolls of fiberglass that can be attached to walls and ceilings. They cost between $0.64 to $1.19 per square foot
- Blown-In Insulation: This insulation involves blowing shredded cellulose into spaces. It is roughly $1.59 per square foot.
- Reflective barriers: Reflective barriers are a type of reflective board that reflects temperatures into necessary places. They are about $0.15 to $0.30 per square foot.
The Price of Insulation If You DIY the Project
Insulation can be a DIY project in some cases, but certain types of insulation like spray foam need a professional to help you out. Not having to pay for labor can definitely result in big savings. Most licensed contractors and insulation installation companies charge about $1.00 to $2.00 per square foot of insulation. This means that you could hypothetically save $2,000 to $3,000 on your project. If you select a cheaper type of insulation and put it in yourself, you could end up insulating your entire hour for just around $1,250. However, most DIY insulation projects are not that cheap. Commercial insulation installers already have all the tools and know-how needed to complete the project. If you do it yourself, you will have to spend a few hundred extra on tools, and any mistakes can mean you pay more to redo the insulation later.
Costs Associated With Replacing Insulation
These prices are all for directly installing insulation in a house that is completely empty of insulation and may not even have walls in place yet. If your house has insulation in place already that you want to remove and replace, you can expect to pay a little more. Part of the expense will be for getting rid of the old insulation. You may also find costs are a little higher if you have to replace walls after installing the insulation. You will need to add about $1 to $2 per square foot to your estimate if you are removing old insulation before you put in new insulation.
As you can see, figuring out how much to save up for your house insulation project is easy. All you need to do is pick your insulation type, decide if you are going to pay for help, and figure out the amount of space you need to insulate. Then you can calculate how much money you need and make sure you are prepared for your home improvement project.
