How much will I pay for Home Insulation?

Want to have the desired temperature in your home all year round and reduce energy costs at the same time? Read on to find out how much home insulation will cost, depending on the type of improvement you wish to make.

What is Home Insulation?

Home insulation uses a variety of techniques to prevent heat from escaping from your home. It is usually achieved by adding a physical barrier between your walls and the outside elements. Home insulation can be applied to the interior and exterior of your home. Its primary purpose is to increase your property’s energy-efficiency and minimize your energy bills - which is always a great outcome!  

What’s the average cost of Home Insulation? 

If you’re thinking about getting home insulation, you’re probably wondering how much it’ll set you back. To make life a little easier, we’ve done our research and calculated the average cost based on prices across Canada: 

Home Insulation Cost Canada
Average cost (in total) $1,500
Minimum cost (in total) $925
Maximum cost (in total) $2,075

Depending on the nature of the work you undertake and the size of your property, home insulation services range from $925  to $2,075 - so it can vary quite a bit! 

Factors influencing costs 

The good thing is that there are different types of insulation services and you can usually find something to suit all budgets! Not all home insulation techniques are expensive, and any improvements you make to your property is better than taking no action at all. 

It’s also good to remember that home insulation will for the most part pay for itself over time in reduced energy bills. External work may also improve your property’s curb appeal, and potentially increasing its value too. 

Let’s take a look at different types of insulation and their costs: 

Type of insulation:

  • Cavity wall 

  • Draught proofing

  • Floor 

  • Loft 

  • Solid wall 

Home Insulation cost by type of insulation
Type of insulationHighest average price Lowest average price
Cavity wall $850$650
Draught proofing $900 $500
Floor $1,100$650
Loft $2,000$1,300
Solid wall $4,000 $2,000

If you’re on a budget, then draught-proofing is an effective and affordable option. At the higher end of the scale is solid wall home insulation, which can cost between $2,000 and $4,000. However, it will offer the very best protection against heat loss overall, as every inch of your external wall space will be insulated. It’s also very beneficial against preventing damp and mould in your home, especially if it’s been caused by an ineffective render.

Cavity wall insulation

Cavity wall insulation works by filling the gap between the layer of bricks with a material that prevents heat transfer. The process is relatively straightforward and requires the installer to drill a series of holes at strategic points in your external brickwork. They will then fill it with a material such as mineral wool, polystyrene beads or polyurethane foam. Cavity wall insulation will cost you between $650 to $850 on average. 

Draught proofing

Draught proofing tackles those certain spots in your home which always feel a little chilly to sit in by removing gaps where warm air is escaping your home. It is the cheapest form of home insulation costing as little as $500 to undertake. You’ll save around $100 on average from draught-proofing, so it’s a worthwhile investment in the long run! 

Floor insulation

As the name suggests, floor insulation adds a layer of insulating material beneath the floorboards. This prevents heat from escaping through your roof space when it rises. Floor insulation costs between $650 to $1,100 on average. But bear in mind that you may have to pay an additional fee for a new carpet if your carpets are ripped up to access the floorboards. 

Loft insulation

Did you know that roughly a quarter of the heat lost in your home escapes through your roof? 

Loft insulation is a thick material that is placed in your roof space, either along the joists or the rafters. The lightweight yet hefty padding creates a physical barrier between the heat rising at the top of the roof. Loft insulation averages at about $1650 and is fairly easy to install.

Solid wall insulation

Older properties that aren’t able to benefit from cavity wall insulation can have solid wall insulation performed instead. The process involves applying installation boards to the external walls of your home. A base coat and a mesh is then applied over the top of the boards to ensure the entire facade is resistant to impact. Finally, a render is applied to complete the job. The advantages of solid wall insulation are two-fold - reduced energy bills and an enhanced home appearance! 

Solid wall insulation costs around $2,000 to $4,000 on average, depending on how big your property is. While it’s the most expensive option, it’s the best way to weatherproof your home. It can also reduce any damp or mould issues that were caused by faulty or even a lack of rendering.

Getting Home Insulation - is it worth the cost? 

Getting home insulation is a well worthy investment if your home has high energy bills or feels drafty in the winter. 

Any home insulation you undertake will make your home greener and reduce your energy bills in the process. In many cases, the work will pay for itself with the money you will save on heating your home.
