Frequently Asked Questions?

  • What are the advantages of loft insulation?

    Loft Insulation Advantages

    Loft insulation is one of the simplest ways to reduce heat loss, improve comfort and help lower energy bills.


    It can also improve your property’s energy performance, reduce wasted heat and make your home or business more efficient.

    • Prevent heat loss
    • Reduce energy bills
    • Helps reduce noise
    • Reduces boiler strain
    • Improves home efficiency
    • Improves EPC performance
    • Reduces wasted heat
    • Boosts resale appeal
  • Do you use spray foam insulation?

    No, we do not use spray foam insulation. Many mortgage lenders and surveyors have concerns about it, especially when it has been applied to roof spaces.


    Some experts have warned that spray foam can make certain properties harder to sell or remortgage.

  • Can I get a grant for insulation?

    Yes, funding may be available depending on your circumstances. You can learn more about insulation grants in NI , and we can help guide you through the process.

  • What type of insulation do you use?

    We use high-performance mineral wool insulation, including trusted products such as Rockwool and our own Clever insulation materials. These are long-lasting, effective and suitable for modern loft insulation work.

  • Is loft insulation flammable?

    The loft insulation we use is made from tried and tested fire-resistant materials. It is suitable for use in loft spaces and can usually be laid around existing electrical cables, depending on the condition and layout of the loft.

  • How long does loft insulation take to install?

    Most standard homes can be completed in half a day to one full day. Larger homes, commercial properties or more complex jobs may take longer.

  • How long will loft insulation last?

    We provide a standard 25-year warranty for effectiveness on our insulation work. The installation can last much longer when the loft is kept dry and properly ventilated.

    We check ventilation at the survey stage and can recommend extra vents where needed.

  • What is loft insulation made of?

    Loft insulation is commonly made from mineral wool, sheep’s wool or fibreglass. The products we use are designed for loft spaces and treated to perform safely and effectively.

  • Does loft insulation cause damp?

    Loft insulation should not cause damp when the loft is properly ventilated. During our survey, we check airflow and can recommend extra ventilation if needed.

    The aim is to keep heat in your home while still allowing the roof space to breathe and release condensation.

  • Can you clear my loft out?

    Yes, this can be included as part of the service. If you need items removed, we offer loft clearance in Belfast and beyond, taking unwanted items away when the job is complete.

  • Can you store items on top of loft insulation?

    We advise against this, as loft insulation becomes less effective when it is compressed by weight. If you need safe storage space, we offer loft boarding in Belfast and beyond, helping protect your insulation while making your attic more practical to use.

  • Does loft insulation make a difference?

    Yes, loft insulation can make a noticeable difference by helping reduce heat loss through the roof. You can learn more in our loft insulation blog .

  • Do you check for woodworm in the loft?

    Yes, during a loft survey we can check visible roof timbers, joists and beams for possible signs of woodworm or timber damage.

    If we notice small exit holes, wood dust or other warning signs, we can let you know before new insulation is installed.


    You can find out more about our woodworm survey in Belfast service here.

  • How long is the wait once booked in?

    We usually have a quick turnaround for local Belfast loft insulation jobs, often around one week. This can depend on the size and scope of the work, but we will always try to work around your schedule.


    Let's Talk
  • Can loft insulation get wet?

    Loft insulation should be kept dry. At the survey stage, we check your roofline for signs of leaks or moisture issues, as wet insulation will not perform properly.

  • What areas do you cover?

    We provide loft insulation across Northern Ireland , including Belfast, Greater Belfast and surrounding areas.
