DIY VS. Professional Insulation Installer: Which is Better?

Want to insulate your property? Deciding between installing the insulation yourself or enlisting the help of professional installers? If you’re a seasoned DIY enthusiast, you may be able to tackle your insulation project yourself. However, some types of insulation require more complex installation that is better left to the experts.

By the end of this blog, you’ll have a better idea of which route to take based on your specific needs. Let’s explore the pros and cons of DIY and professional insulation installation to help you make an informed choice.

Pros of DIY Installation

Cost Savings

This is perhaps one of the most significant advantages of DIY insulation. When you eliminate labour costs, you can reduce your overall expenses, saving money for another area of your project or simply for a rainy day.

For example, installing fibreglass or glass mineral wool insulation, like our Loft Insulation Superglass Multi Roll – 44, is relatively straightforward and affordable, making it a great option for homeowners conscious of their budgets.


Taking on an insulation installation project can be both convenient and flexible for DIY enthusiasts. By doing the job yourself, you can work at your own pace and fit the work around your schedule without having to coordinate with contractors.

This flexibility is particularly beneficial for those who enjoy weekend projects and completing home improvements themselves.

Personal Satisfaction

There’s a profound sense of satisfaction and accomplishment that comes with completing a home improvement project with your own hands. Beyond immediate gratification, DIY insulation also offers a learning experience.

As you work, you’ll learn more about the process and your home’s structure, which can be hugely beneficial for future home projects.

Cons of DIY Installation


When undertaking any DIY project, safety is a significant consideration. Insulating your home often involves the handling of potentially hazardous materials and climbing into attics or other confined spaces. Without the proper precautions, you risk injuries from falls or exposure to the damaging fibres of some insulation products.

Risk of Poor Installation

Improper installation is a common issue with DIY insulation. Although you may feel capable of carrying out the project yourself, without professional expertise, you run the risk of leaving gaps or compressing the insulation, both of which can reduce effectiveness. Improper installation can also lead to higher energy costs and reduced thermal comfort in your home.


Taking on a DIY insulation installation project can be both time consuming and physically demanding. Depending on the size of the area to be insulated, the entire process could take several weeks to complete. Additionally, the physical labour involved can be taxing, especially if you’re not used to such work.

Pros of Professional Installation

Expertise and Experience

Professional installers bring a level of expertise and experience that outshines any DIY installation. Skilled in the proper techniques, professional installers ensure the insulation is applied correctly and efficiently for optimal performance.

For insulation types that require more complex installation, like our 90mm PIR T&G Cavity Wall Sheet Part Fill, the expertise of professional installers is invaluable.

Compliance with Building Codes and Regulations

As they’re familiar with building codes and regulations, professional installers can ensure that your project complies with all necessary standards, reducing the risk of legal issues, fines, and potential safety hazards.

Guarantees and Warranties

When you hire a professional installer, they often come with the added benefit of guarantees and warranties. This offers peace of mind for your insulation installation, as you know that if something goes wrong, you’re covered. Professional installers usually offer warranties on both the materials and their workmanship.

Cons of Professional Installation

Higher Upfront Costs

Professional installation is significantly more expensive than DIY installation. This is because you’re also paying for the cost of skilled labour and specialised tools. However, the long-term savings in energy expenses can significantly outweigh the cost of professional installation.

Scheduling Constraints

You’ll need to coordinate your schedule with that of the professional installers. This can sometimes be difficult, especially if you work full-time. It can lead to delays and inconvenience, especially during peak seasons when contractors are in high demand.

Possible Quality Variation

Although professional installers offer better quality installation than a DIY’er, the quality of professional installation can vary depending on the contractor you hire. Be sure to do your research and choose an experienced and reputable installer to ensure high-quality work.

Ready to Decide?

When deciding between DIY and professional insulation installation, it’s essential to assess the cost, time, safety, and long-term benefits of both. Perhaps the most important consideration is your skill level. If you feel confident in your abilities and enjoy taking on home improvement projects, DIY could be a cost-effective and highly rewarding option.

However, if you prefer the assurance of expert workmanship and adherence to building codes, investing in professional installation could offer better peace of mind and possible greater long-term results. Ultimately, the right choice depends on your unique situation and priorities.
