Our Reputation Speaks for Itself
The initial interview was conducted at a leisurely pace and everything was explained in detail. The installation was carried out by two very polite gentleman. They explained what work would take place. They were efficient and informed me several times at what stage the installation was up-to. On completion of the work I inspected their workmanship and the total installation.
The two workers which were sent arrived promptly. They were very polite and kept us informed of everything they were doing. Instead of taking the arranged two days they worked later and finished the job in one, they cleaned up everything to a very high standard. I would definitely recommend this company to anyone needing their spray foam removed. Very impressed.
Cant fault the company or the operatives working on my property we had foam taken from our rafters with dry ice, the 2nd part was was the foil covering the roof trusses all the working men cleared up cleaning carpets etc. i now have peace of mind
Jamie and Marcel came to line my roof with super foil after David, the surveyor had been to check it. Great guys, all 3. Thank you for making the ecperience enjoyable. I have refered a friend and have given Safe Eco-Fixes Ltd details. Thanks again

Frequently Asked Questions (FAQs)
Find answers to some of our most frequently asked insulation service questions.
Why should I remove spray foam insulation?
Spray foam may need removal if it was poorly installed, has deteriorated over time, or if you're planning renovations or selling your home. It can trap moisture, affect structural integrity, or fail to meet surveyor standards.
Is spray foam removal safe for my property?
Yes. At SEF Ltd, we use specialist tools and follow strict safety protocols to ensure the insulation is removed without damaging your roof or internal structures.
What makes SuperFoil insulation different from traditional materials?
SuperFoil is a NASA-inspired multi-foil product that reflects up to 95% of radiant heat. It acts as an insulation layer, vapor control, and radiant barrier all in one — making it highly efficient and space-saving.
Can SuperFoil be used in both old and new properties?
Absolutely. SuperFoil is ideal for both retrofit and new builds. It can be used in roofs, walls, and floors — either alone or combined with other insulation types for optimal results.
How long does cavity wall or spray foam work take?
Most installations or removals are completed within a day or two, depending on the size of the property. Our team will give you a tailored schedule during your assessment.
Are your insulation services compliant with UK regulations?
Yes. All our materials are fully certified, and our team adheres to the latest UK building regulations. SuperFoil is CE/UKCA marked and approved for use under the IAA and Quality Mark Protection.
