  • At Professional Spray Foam Removal Ltd. we specialise in the safe and efficient removal of both closed-cell and open-cell spray foam insulation from lofts. Many properties with spray foam insulation face issues such as poor ventilation, trapped moisture, or problems with mortgage approvals. Our team provides a reliable solution by carefully removing faulty insulation and replacing it with modern, high-performance loft insulation that meets current standards. We pride ourselves on offering a professional service from start to finish. Every project begins with a thorough assessment, followed by safe removal using the right tools and methods to protect your roof structure. Once the spray foam is cleared, we install fresh loft insulation designed to improve energy efficiency, reduce heating bills, and create a healthier living environment. With years of experience in insulation and loft work, we understand the importance of quality workmanship, clear communication, and customer care. Whether you are a homeowner looking to improve your property’s energy rating, or preparing to sell and need old spray foam removed to satisfy surveyors, we can help. Our goal is simple: to provide you with peace of mind, a warmer home, and insulation.
