    We approached Simon back in July for a quote to spray our metal fabricated 9000sq ft building. We've been having condensation and damp problems for years. He came and did a full inspection and listened to all our requests and talked through the job. The building isn't empty and couldn't be fully emptied and there are some access issues. Despite this Simon and Chris were able to complete the job sooner than they estimated initially. They meticulously covered anything we forgot to and worked diligently. The building is now warm and dry, with no condensation able to form. They cleaned everything and left the place as they found it. We are beyond thrilled. Would not hesitate to recommend them and to use their services again in the future.

    Dear Lauren Thank you so much for your kind words. It was a pleasure completing the anti-condensation treatment to the metal roof cladding of your agricultural building with closed cell polyurethane spray foam insulation. We look forward to working with you again soon. Kind regards Simon Vasey Isotech

    Simon and Chris were amazing. I asked them to spray foam the under side of a roof and the job is perfect. Great application throughout with attention to detail and a brilliant clean up job after. The foam has also increased the strength and integrity of the roof. great value for money and a solid product from a good team of people. Thanks.

    Dear Mat Many thanks for your kind words. It was a pleasure working for you applying closed cell polyurethane foam to the roof substrate of your mobile home. Good luck with the completion of the project and your subsequent adventures. I'm sure that the insulation will ensure that you are comfortable all year round. Kind regards Simon Vasey Isotech Sprayfoam Ltd

    This company mis-sold its product to the previous owner of our house. Maybe it's fine for barns, but not homes. Now we have come to relocate due to work, no one will mortgage our house because of the spray foam. It is bonded directly to the slates and therefore we need it removed and a WHOLE NEW ROOF fitted at approx. cost of £10,000 in order to sell our house. The slates cannot even be salvaged. DO NOT USE THIS PRODUCT ON YOUR HOUSE! Words cannot express what a nightmare we are currently living in because of this.

    Re: This company mis-sold its ...
    Isotech Sprayfoam Ltd replied on Friday, July 30th 2021

    Dear Mrs Goodhand I am sorry that the lender of your prospective housebuyer has refused them a mortgage on the grounds that sprayed foam was installed by us to the underside of the roof covering for the previous owner of your property in 2009, 12 years ago. We were invited by the previous owner to carry out a full survey of the roof and provide a detailed written quotation. Our client was made fully aware of the process involved at that time. We strongly refute your libelous assertion that we 'mis-sold' this product in any way. At that time the Royal Institute of Chartered Surveyors certainly had no issues with the installation of this product, as you no doubt could testify when you came to secure a mortgage to purchase the property from our client. Up to now, there have been no issues with this installation in the 12 years since we carried out this work. We are manufacturer approved installers of this BBA Certificated system with 35 years of experience and the work was carried out by myself in a professional and competent manner. It is only in the last year or so that we have been made aware that, due to some failed applications to properties unsuitable for treatment by unregulated installers, some building society tick box surveys have red flaged sprayed foam if it is identified during their cursery 'head and shoulders' loft hatch inspection, rather than evalute whether the installation has been carried out in a professional and competent manner or is actually having a detrimental effect to the fabric of the property. There are literally hundreds of thousands of successful installations of this product in the UK and many times more than that worldwide. The National Insulation Association is in active dialogue with RICS to address this issue and establish a more nuanced approach whereby the installation can be assessed more constructively. Until this matter is resolved, we have suspended installing the product to the underside of domestic roofs, where it will remain visible in the future. Whilst I sympathise with your current predicament and hope that you will soon be able to find a buyer with a more understanding lending criteria, I am disappointed that you chose to post your negative and frankly libelous reveiw on our Google business profile page without providing us the right to reply to your initial email received just 24 hours earlier. Yours sincerely Simon Vasey Director Isotech Sprayfoam Ltd

    Isotech Sprayfoam completed a job for me today - a large commercial workshop roof.
    The entire process has been superb, from the initial call out to see what the job entailed through to the finished job.
    The guys did an excellent job sheeting and protecting all areas that weren't going to be insulated and once they had left site I think it was actually cleaner than when they had arrived!
    The warmth being retained in the workshop now is beyond what I was hoping for! I couldn't be happier - bring it on winter!!

    I would thoroughly recommend the team at Isotech to anyone needing spray insulation applied or any advice regarding it!

    We shall be in contact in the future once the rest of our workshops are ready for you.

    Many thanks,
