How Much Does it Cost To Spray Foam a House


how much does it cost to spray foam a house

Home-owners find it hard to get an exact figure on how much it costs to insulate a house with spray foam, and there is a reason why. There is a plethora of different insulations on the market, with different capabilities and insular performance available.

This makes choosing the right product more difficult and it is worth speaking to an expert when working out the question ‘how much does it cost to spray foam a house?’

When customers ask us what the best building materials on the market are for insulation, we always respond with LogicFoam. We are the only BBA approved pitched roof installer in the whole country who are licensed to sell LogicFoam, making us the countries preferred installers.

As we are a direct supplier of LogicFoam you can also benefit from a reduced rate, most companies representing the product are sales companies and pass through any sales through to companies such as ourselves, whilst taking their cut at the same time.

There are a number of additional factors which contribute towards the price of home insulation which include but are not limited to:

  • The type of foam you need for your project
  • Accessibility
  • Size of property
  • Thickness of insulation
  • Company you buy from (most companies are third parties LogicFoam are the country's official installers so you can benefit from reduced rates)

Let's consider each cost determiner in a little more detail...

Spray Foam Cost Determiners: 5 Key Factors

Spray Foam Cost Determiner No.1: The Type Of Foam

Closed cell spray foam is far denser than open-celled varieties, and is, consequently, more expensive than open celled foam. Although it has a slightly higher R value than open celled equivalents, it is generally best suited for use in commercial applications.

For residential properties, open celled foam is most appropriate-and considerably less costly as well.

Spray Foam Cost Determiner No.2: Accessibility

Certain property constructions possess much more convoluted designs, making them challenging to insulate. In these instances, the inaccessibility of the area to insulate can cause costs to soar, with more manpower required to work around this problem.

Thankfully, spray foam can accommodate all sizes and shapes of space-making it the ideal solution for hard-to-reach areas, such as around pipework and ductwork. What's more, unlike conventional methods, such as cellulose, awkward shaped areas require no additional manpower to insulate, enabling you to keep costs in check-regardless of the complexities of the design.

By enlisting a professional installer, you can rest assured that the foam will be applied in the correct amounts.

Spray Foam Cost Determiner No.3: Size Of Property

Another key cost determiner is the overall size of your property. Put simply, the larger your home, the greater the amount of insulation it will require.

However, if you're looking to keep costs in check, prioritising insulating the roof space makes sound financial sense. According to the Energy Saving Trust, in an uninsulated home, a quarter of heat is lost through the roof, making it the best place to begin when upgrading your insulation.

Spray Foam Cost Determiner No.4: Thickness Of Insulation

When considering spray foam for the home, homeowners fall into 2 key categories: those currently with no insulation (predominantly in older homes), and those that have outdated insulation installed that desperately needs upgrading.

One common misconception that exists is that the more insulation applied, the better the performance overall. To a certain level, this is true; yet it should also be noted that if spray foam is applied surplus to requirements, it can 'bulge' out from the rafters, making it both unsightly and ineffective.

However, by enlisting a professional installer, you can rest assured that the foam will be installed in the right amounts for you to capitalise on its benefits long-term.

A trustworthy company should always encourage questions from customers-and provide detailed answers and info

Spray Foam Cost Determiner No.5: Your Choice Of Company

It's no secret that prices can vary wildly between different companies. Always aim to drill into the details of each individual quote your receive; a price that may look promising on the face of it may be substantially lower because an inferior product will be used, or the work may not come complete with a long-term warranty should future problems arise. 

A trustworthy company should always encourage your questions-if they squirm or seem to avoid answering them directly, then alarm bells should start to ring; they are unlikely to have the requisite experience to tackle the task at hand. The result? Additional outlay later on as you attempt to fix their botched attempt.

Leaking Air = Leaking Money

Air can escape through the leakage points in our home, and these holes can be smaller than a millimetre wide. Even using insulations such as fibreglass you are not achieving full insular value in your property as the product is not able to fill these tiny gaps that appear.

Spray foam insulation expands up to 100 times its size, allowing complete elimination of any air leakage points and filling gaps previously accessible from other methods of insulation.

40% of heat is lost through these leakage points, with the majority escaping through the attic. Whether insulating an old home, retro fitting or thinking of using spray foam in a new build, consider talking to one of our experts for a free property survey to see if you are suitable.

How Much Heat Is Lost?

If you have no insulation in your attic you are losing out on money and home comfort, it is an issue that needs to be addressed as soon as possible. Imagine having a shaven head (if you don’t already), what’s the difference between wearing a hat on a cold winters day and not wearing one?

Don't let chilly conditions compromising your comfort and costs; insulate with spray foam insulation instead

The answer is a lot: by losing 40% of heat through uninsulated areas, you are reducing your chance of home comforts, and increasing the cost of your energy bills.

The more quotes you get, the more likely you'll get the very best deal on offer. Needless to say, it pays to shop around!

How Can I Get The Very Best Deal On Offer?

Top Tip No.1: ALWAYS Shop Around

We all live increasingly busy lives, and, consequently, setting aside time for multiple appointments and surveys can be feel like a considerable challenge. Yet settling on the quote from the first contractor you come across is inadvisable for several reasons:

Firstly, unless you have substantial knowledge of the spray foam industry as a whole, it's difficult to discern whether the quotes price is good value-as well as whether it's an accurate representation of the average cost as a whole.

Secondly, if a contractor is aware that they are the only installer quoting, they're far less likely to get as sharp with their pencils as they should do. When they're aware that they're one of many companies quoting, they know they need to fight harder to secure your custom-and will offer a far more competitive quote to achieve this aim.

Thirdly, the more quotes you get, the more likely you'll get the very best deal on offer. After several quotes, you should get a solid grasp of the price you can expect to pay, and can then start to focus on the additional plus points offered by each company in turn.

Bear in mind that a legitimate company should always offer a 25 year warranty, so check that this is offered when each contractor comes out to quote. 

Top Tip No.2: Ask For Recommendations

One of the best ways of sorting the cowboys from the credible contractors is to ask for recommendations. Friends, family members and neighbours all provide invaluable advice on key aspects of a company's service. You'll also be able to see the results they received first hand when you come to visit. 

They'll also be able to inform you not only of the job itself, but the standard of aftercare they obtained. A trustworthy contractor always goes above and beyond the call of duty. They should clean up after themselves, and also make several follow up calls later down the line to check that the installation is still performing effectively.

Many homeowners fail to realise that you will get a far better price for bulk orders, rather than tackling one task at a time

Top Tip No.3: Consider Several Renovations At Once

When it comes to renovating our homes, we usually have more than one project in the pipeline-yet cost constrictions mean that, on the whole, we tackle one task at a time.

Although it's easy to understand the thinking behind this approach, what many homeowners fail to realise is that you will invariably get a far better price for bulk orders.

In general, spray foam companies specialise in more than one product, so chances are, if you are also considering upgrading your windows in the not so distant future, you will receive a far more competitive quote than if you were to quote each project proposal one by one.

Top Tip No.4: Seek Out Seasonal Discounts

Despite the fact that spray foam installation takes place all year round, there are several primary times when seasonal discounts come to the fore.

An obvious contender is Christmas; the majority of home improvement companies close for two weeks during the festive season meaning they are keen to close deals in early December, rather than wait until they reopen in January.

Consequently, you'll find that the majority of companies offer seasonal discounts in the run up to Christmas, making early December a good time to secure a competitive deal.

In general, home improvement companies worth their merit offer a variety of payment plans to suit your circumstances

Top Tip No.5: Enquire About Paying In Instalments

For those on a tighter budget, paying for spray foam installation in whole can seem prohibitive. However, what most homeowners fail to realise is that this doesn't have to be the case; in general, home improvement companies offer a variety of payment plans to suit.

A popular option among property owners is to pay for the project in monthly instalments. This helps to stagger the cost, making it far more manageable rather than paying in full upfront.
