Jon & Jill Coote

“Further to Phil’s return visit today to re-check and re-calibrate our MHRV system, after our booster switches were rewired correctly, we would just like to state how much we appreciate the very professional and efficient service that you have both provided to us. You have both been reliable, friendly and accurate, and always ready to answer all of our questions and queries. We carefully installed the system ourselves and your commissioning and testing continued that same attention to detail, and a commitment to get it working at its most efficient, in terms of both sufficient air movement and at the lowest acoustic level.”

Lewis Whiteoak (Self Build Developer)

“Phil, good to meet you today, and thank you for carrying out the test. Really glad i choose your company to do the test. I will definitely recommend you to other developers and will be using you again in the future. Really glad it passed today and hopefully with future developments it won’t be so close after the information you passed on to me.”

Tim Colburt (Developer)

“I used Northern Air Tightness Testing Services during a single house development. Both Mike and Phil were extremely helpful throughout the build and were happy to provide free advice both via the telephone, but also several site visits. They maintained regular contact and would call in when passing. Their advice and tips in preparation for the final air test were invaluable and without their help, I doubt we would have achieved such a good outcome. They are clearly very knowledgeable and I would not hesitate to recommend them. My advice would be to get them involved at an early stage of your build and utilise their skills, it will definitely save you money but more importantly will give you peace of mind and one less thing to worry about.”

Gary Horton, Mayfair Property Group

“ Thank you for your very professional job, also please tell Hannah excellent customer service, makes a welcome change to meet a customer focused company.”

Chris Simpson (Self Build)

“ Thanks for the speedy response with report and certificate and for all your help with this process. The service you have provided has been extremely thorough and professional and guidance throughout has helped immeasurably with progress toward Building Control sign off. It’s my intention to make use of your services again for future projects, particularly before we reach second fix, helping insure that we maximize air tightness, without the need for remedial work to mitigate at the testing stage. It’s been a pleasure.”

Rosalind Woods, Small Building Services Ltd

“ Mike and Phil are thorough, conscientious, helpful, polite, knowledgeable, reliable and attend to their work promptly. I am very happy to use them on my projects and can recommend then to my customers with confidence.”
