In some case's its ok to lay new batts over old batts, but we strongly recommend removing any old insulation prior to install new insulation as old insulation often is home to rodents and contains large amounts of dust, animal faeces and other allergens which could cause potential health hazards to the occupants of the home. New insulation should never be installed over old cellulose or blown-in insulation as the dust collected over time makes cellulose heavier than batts causing the home owner a potential risk of roof collapse if new insulation is placed on top.







Insulation acts as a barrier to heat flow and is essential to keep your home warm in winter and cool in summer. A well insulated and well designed home will provide year-round comfort, cutting cooling and heating bills by up to half. This, in turn, will reduce greenhouse gas emissions.​







Prices vary depending on the size of the house, access to the insulation, amount of insulation needed to be removed and disposable costs.






As a general rule, we allow one full day give or take based on the factors outlined above. Contact us for a more accurate quote on the time taken for removal in your home.







​Almost every home has​ a manhole allowing easy access into the roof space, however we recommend that we access  the roof from the exterior of your home by  removing roof tiles. This method offers the most hygienic solution and ease for us by providing adequate ventilation and light, although we will leave this decision up to you.







Since we access the roof from the exterior,  it is safe for occupants of the home to be on premises, but as a precaution we recommend that all young children and pregnant women leave the premises for safety precautions.







Insulation Extract requires 40% upfront payment and 60% on delivery for our insulation removal, insulation install and extraction services. We offer flexible payment methods of cash, cheque or electronic transfer. We strongly recommends the area is inspected before final payment is made.
