Diy Vs Hiring An Attic Insulation Pro
For most attic insulation projects, its best to hire an attic insulation company near you. Although adding some of these materials might not be too difficult, its best to have a pro to help you determine if you can keep what you have and what amount to add.
When it comes to removing insulation, some typessuch as blown-in and loose-fill insulationwill require special training and equipment, such as an industrial hose. Also, older insulation materials like loose-fill may contain dangerous asbestos, which you shouldnt handle on your own.
Polystyrene Attic Insulation Price
The cost of polystyrene attic insulation ranges from $1,000 to $9,000. Polystyrene is a foam insulation type. It can be found in spray foam and foam board. It can be expanded or extruded, which changes the materials properties and how well it insulates. Extruded polystyrene insulates better, and while both are flame retardant, expanded polystyrene can melt, and extruded does not. Polystyrene can cover the underside of the roof deck and floors and walls in the attic.

Whole House Insulation Cost
The cost to insulate a 2,000 sq.ft. house is $1,200 to $30,000, but costs can be lower for smaller homes or higher for larger homes. These costs reflect the least expensive and most expensive insulation types in their range. While most homes use a mix of materials with a cost range of $3,300 to $25,000, if you insulate every area with the minimum amount of fiberglass batts, your costs would be at the very low end. At the other end is insulating your entire home with the maximum amount of spray foam insulation. Many spaces can be insulated, including wall cavities, ceilings, basements, attics, and crawl spaces. Most homes use a combination of insulations, but you can use just one type. Costs can be much lower when insulating in new construction, and they may be higher for existing spaces, particularly if the spaces are hard to access.
How To Tell If Your Attic Needs Insulation
Here are some of the signs you may need new insulation in the attic:
- Snow melting on your roof. If the snow on your roof is melting before the snow on your garage, heat could be escaping from your roof and melting the snow.
- Ice dams form on the edges of your roof. Ice damming can mean poor insulation or poor ventilation. If the ventilation isnt right, then there is a possibility that you have a traditional attic system with insulation on the floor of the attic and venting that runs up the roof deck. Even with proper ventilation, you can still get ice damming if there is heat escaping.
- High energy bills. Your energy bills may be through the roof if your furnace or air conditioner is running constantly due to poor insulation.
- The upstairs rooms dont stay warm during the winter. A common complaint is that the rooms on the second floor dont stay warm, despite the furnace continuing to run.
- You replace your roof more often than normal. It isnt normal to replace your roof every 10 to 12 years. The average lifespan of a roof is between 30 and 40 years. If you find yourself frequently replacing your roof, then you could have a moisture problem stemming from poor insulation.

Cost To Insulate A 1000 Sqft Attic
The full cost range to insulate a 1,000 sq.ft. attic is $1,000 to $7,000, with most people paying between $2,000 and $3,250. 1,000 sq.ft. is one of the most common sizes for attics. Insulation can be added to the floors and walls between joists. It can also be added to the roof decks underside. It is common to use batts between joists, blown-in insulation to cover the floors, and spray foam may be used in walls or on the underside of the roof deck.
Insulating A Cathedral Ceiling Cost
The cost to insulate a cathedral ceiling averages $500 to $2,000 for a ceiling that is roughly 500 sq.ft. Many companies have minimums of $1,500 to $2,000. When insulating a small ceiling, you may want to do so as part of a larger project. Insulating cathedral ceilings is important for ceiling areas to remain close to room temperature and allow for evenly distributed temperatures.
For ceilings, there must be space between the roof deck and ceiling for adequate installation. Batt insulation, typically foil-faced insulation, is often used for cathedral ceiling installations.

Cost To Replace Attic Insulation
If your attic insulation is old, degraded, or disturbed by pests, you may want to consider replacing it. Removing old insulation has a cost range of $1 to $3 a square foot. This is in addition to the average costs of adding new insulation to the attic. For an average 1,000 sq.ft. attic, the costs to remove the insulation are $1,000 to $3,000 plus the average costs to install new insulation, giving a total of $3,000 to $6,250 for most attics.
If the insulation is in good condition, you do not need to remove it to add more. You can add more insulation to your existing attic insulation to bring your R-values to the recommended total.
Closed Cell Spray Foam
This SPF insulation might be the best home insulation available but it is also the costliest and doesnt make financial sense for all areas.
In the attic, its best application is for the walls of the attic and over vent areas such as gable vents and soffit vents.
Closed cell SPF creates a vapor and moisture barrier. That means it seals the surface against air leaks and moisture penetration.
Cost: $5.35 to $6.75 per square foot based on application thickness. A minimum of two inches should be applied to insure a seal against airflow.

New Construction Insulation Cost
The average cost to insulate a home during new construction ranges from $0.65 to $6.50 a square foot. Several types are good for new construction. The most common is to use batt insulation in the walls and ceilings and spray foam or loose-fill in open areas. You may also use some types of rigid insulation board on the exterior before it is sided. It is very common for new construction to use several types, but you can also choose one to keep costs down.
Spray Foam Pole Barn Cost
Installing spray foam in a pole barn costs$3,500 to $16,500, depending on the project size, foam type, and climate zone. Closed-cell spray foam works best for pole barns because it adds structural strength and doubles as a vapor barrier.
- Insulate the roof and walls when using the pole barn for storage or recreation.
- Insulate only the roof if the pole barn houses livestock.

How To Know If Your Attic Needs Insulation
You can determine if your attic needs insulation in several ways. The first is look and measure. Most homes need a minimum of 10 to 14 of insulation on the attic floor. If you find less than this, you may need to add more.
Other signs are harder to pinpoint and measure but can be obvious if you are looking for them. The first is ice dams forming on your roof in the winter. If your warm air is escaping into the attic, it melts the snow on your roof, where it runs to the edge and re-freezes.
Another sign is temperature variances between floors. If the rooms just below your attic are harder to keep warm in the winter or are getting very hot in the summer, it can be a sign of needing more attic insulation. Feeling drafts in these areas can also be a sign.
Finally, speak to your neighbors. If your energy bills are higher than other homes in your area that are about the same size, it can be an indicator that you need additional attic insulation.

Factors Affecting The Cost Of Ceiling Insulation
There are multiple factors which may affect the cost to insulate a ceiling in your home. However, the most significant cost factors likely to affect the cost include:
- Where You Live There are very specific recommendations for the levels of insulation required for ceilings, depending on where you live. R-values for ceiling vary greatly, from as low as R-13 to as high as R-60. Insulation with R-values as low as R-13 may only cost between $0.90 and $1.40 per sq.ft installed for roll or batt insulation, but insulation with R-values closer to R-60 for locations like southern areas of the coast of California may cost $4.80 to $8.65 per sq.ft for spray in foam insulation. Because of this variation, we recommend getting estimates from local contractors.
- Size of Your Ceiling Obviously, ceilings with a larger surface area will require more material and therefore costs will be higher.
- Height of Your Ceiling Not one that people often consider when costing out their insulation project, but the higher up the ceiling then the more complex the installation may be due to the need for extras such as scaffholding platforms or taller ladders. This may make installation more difficult and therefore increase overall labor costs.
- DIY or Pro Install yourself, it will take more time and more hassle but youll save on the labor costs which can range between $0.60 to $0.95 per sq.ft for cheaper roll and batt insulation to $0.90 to $1.40 oer sq.ft. for more costly spray in foam insulation.
Cost To Insulate Garage
Itll cost $0.50 to $1.25 per square foot to insulate a garage. A professional installation may double that price, which doesnt include the garage door. The total price ranges from $1,500 to $8,000 depending on the materials you choose and the size of the space.
Attached garages only need the outside walls insulated, not anything connected to the main home. Insulating a garage door with rigid foam or batts costs about $200 to $300 for a 9-foot-tall door.

Cost To Insulate A Room
The average cost to insulate a room ranges from $800 to $8,000, assuming a room size of between 400 and 800 sq.ft. The spaces in the room to insulate may include the ceiling, one or more exterior walls, and possibly the space below. Most companies have minimum charges of $1,500 to $2,000, so when insulating a small room or a part of a room, you may want to include this as part of a larger project. Rooms may be insulated with batts, loose-fill, or spray foam, depending on the area.
How Much Does Roof Insulation Cost Per Square Metre
A range of products leads to a wide range of pricing. If you start with a 100-square metre area without access issues, fibreglass roof insulation cost is about $1,100, which breaks down to about $11 per square metre. A polyester product may double that, increasing the price to $2,200 overall and $22 per square metre.

Loft Insulation Cost: 2022 Price Comparison Uk
Insulating your loft or attic is essential in the present era of high energy costs. According to the Energy Saving Trust, we lose 25% of our home heat through an uninsulated roof. Therefore, we should make our homes more energy-efficient, thus reducing our heating bills.
In the UK, the average cost of insulating a loft varies with materials. But, a fibreglass blanket costs £8/m2 for 3-layers, or £360 in a semi-detached house, and £250/day for labour. The prices of other insulation vary, and well discuss these later.
As you probably already know, heat rises. Therefore, warmth from your radiators rises into the loft space, where its lost through the roof. This makes your heating system work harder to maintain an acceptable temperature
Suppose you intend to build a house extension, conversion or replace your heating system. In that case, the local authority building control inspector will ask about existing insulation and compare it to the requirements recommended by the Building Regulations. If theres a shortfall, you must upgrade the lofts insulation thickness as part of the project. You can do this yourself with some insulation types. But, its better to hire a professional loft insulation company having the manpower, equipment, and safety knowledge to insulate your loft to comply with the regulations. However, if you cant afford the loft insulation prices when upgrading insulation, government grants are available if your circumstances meet the criteria.
Cost To Spray Foam An Attic
The average cost to install spray foam in an attic is $2,500 to $12,000. Spray foam is liquid insulation that solidifies on contact with the substrate it is installed on. At this point, it expands to many times its size. Spray foam does a superior job of insulating areas like the underside of roof decks and hard-to-reach areas around pipes and corners. It can be added to traffic areas or used in combination with other materials. It can be found in different formulas, some of which are more eco-friendly than others.

The Number One Prep Step: Seal Air Leaks
Gaps in the attic or between the lower floors and the attic will let heated air escape to the great, unconditioned outdoors, making any insulation you add essentially useless. Here’s a quick primer on fixing draft-prone spots.
Thinking Of Finishing The Attic Someday
If you’re considering turning your attic into conditioned storage or living space, it’s worth changing tactics to insulate between the rafters and wall joists instead of the floor. You can use rigid foam panels or do as Tom Silva does with nearly all houses these days: Hire a pro to install spray foam insulation.
Foam blocks airflow needs no vapor barrier and has a higher R-value per inch than loose fill or batts, so you’ll get more protection with less depth. With spray foam, unlike with loose fill or batts, you must cover the soffit vents . Then cover the foam with drywall as required for fire safety.

How Much Does Spray Foam Insulation Cost
Installing spray foam insulation costs around $3.25 per 1 square foot of your house area, for Open Cell insulation, and around $6.30 for Closed Cell. This would include insulating exterior walls and attic space with R-Values that meet the building code.
PRO TIP: This calculator is designed to estimate insulating your whole house, and only with Spray Foam insulation. We have made an Attic Insulation calculator , which allows you to also get quotes for Blown-in, Roll / Batt fiberglass & mineral wool insulation, as well as SPF, and is made specifically for attics.
The two main types of spray foam insulation are Closed Cell which provides about 6.75-7 R-value per 1 inch of thickness & Open cell which provides about 3.5R-value per 1 inch.
The actual cost difference between these two types is about 50%. However R-Value is nearly double for Closed Cell vs Open Cell. Therefore, heat loss with a Closed Cell will be significantly lower!
Spray Foam insulation is the most energy efficient type of home insulating materials. It provides a leak-tight envelope, and reduces heat loss.
