Highlights
“Just had a new unit fit under their 10 year guarantee. In all honesty they could have refused to honour it as I hadn't replaced the filter after 5 yrs which is required. Vanessa was dealing with it and was very quick in coming to a decision and arranging an engineer visit. The engineer (Micky) was very knowledgeable and friendly. He quickly diagnosed the fault and replaced the unit. Really good service from all concerned and I must say these units really do stop mould returning.”
“We had terrible problems with condensation in our sheltered house. This ventilation system sorted it out very quickly. The engineer was very professional and explained everything to us. As a retired manager of a builders merchant he is definitely one of the best I have seen.”
“Highly recommend from start to finish Stacey and Mat were brilliant. They addressed my concerns and worries. The unit was fitted in a week, the engineer was on time and took time to explain everything I'm very happy, EnviroVent North”

Piv unit does exactly what its advertised to do
Got a PIV unit fitted to deal with mould and condensation. After a week no more wet windows and thr mould has gone. The surveyor turned up when he said and told us the facts not just a sales pitch. Engineers arrived when stated. No mess no noise minimal fuss. Not much more to say. Great dealing with a company in the UK and Matt the surveyor always answered my calls or texts when i had questions
Game Changer
We had a PIV installed in our bungalow and overnight the condensation on our doors and windows disappeared. It’s a considered purchase but we felt that the whole process was clearly set out by the rep and the work carried out to a high standard. If you suffer from condensation then consider Envirovent we are extremely pleased with the results especially as we had bought new windows and shutters.
Bathroom installation
Shai did the initial survey and recommended the Cyclone 8 extractor. I had confidence in Shai's professional approach and agreed to make the purchase. On the installation day, the engineer arrived on time and proceeded to install the extractor. After the installation, the engineer demonstrated how to maintain/clean the extractor. I am satisfied with the survey and the installation, both surveyor and engineer did a good job. The extractor is working fine an I am glad I made the purchase.
Warranty work

A lifesaver for our loft problems
Matthew from EnviroVent was a huge help with the issues we were facing in our loft space. He gave us clear, honest advice about the mould and ventilation problems (caused by poor installation from the developers) His knowledge and guidance made a real difference and saved us an incredible amount of stress and money.
Outstanding
Matthew who did our survey from.northeast area was outstanding he knew exactly what was needed as bellway had fitted inadequate fans he was freindly, understanding, exceptional knowledge, no pushy sales and respected my home ,Phil fitted 2x cyclone 8 fans he was excellent clean,tidy,respectful outstanding work Phil thankyou so much matt and Phil angie and mike 👏
Positive input ventilation and bathroom extractor fan
When renovating our 1930s semi we wanted to improve ventilation and were recommended to talk with Envirovent. Sam Hawkins came to do an inspection and I was impressed with his expertise. He recommended to install a Positive Input Ventilation system (Atmos) and a new bathroom extractor fan (Cyclone), and promptly followed up with detailed quotes after the visit. Sam was very thorough in answering all my follow up questions. The Envirovent systems needed access to outside air as well as sufficiently ventilated loft space, which we were able to ensure as part of roofing work taking place around the same time. Sam patiently worked with me and the roofer to ensure the right types of tile vents were placed in the right locations. Then the Envirovent engineer Adam Hornett was then able to complete the installations according to plan, with both the Atmos and Cyclone running well since then (one and a half month ago). We are hopeful that these systems will help to keep dampness at bay for many years to come, especially during the cooler months.
Helpful Service
Matthew Mazzucchi was very helpful and demonstrated the system and answered all my questions concerning the installation. He organised additional workmen such as the roofer and electrician. Informed of installation date well in advance, and the installation man arrived early and on time. No mess was left behind. The system is quiet and seems to be working well. The air is fresher and the windows are dry. We had an extractor fan installed in the kitchen, and has made a huge difference when cooking vegetables. The walls are no longer soaking wet. I highly recommend Matthew and EnviroVent.
Perfect solution to condensation
We are a 2-bed ground floor flat and had the most horrendous condensation problem. We had water running down the bedroom walls at times, mold spores and ruined clothes, bedding and the flat smelt musty. EnviroVent came and did a survey and gave us the advice and demonstrated the ATMOS passive unit and A Cyclone7 extractor for the bathroom. We couldn't believe that this unit would actually work, but with the money back guarantee offered we went ahead. The results are fantastic we have no more condensation, the air is fresh, no more mold on the ceilings its brilliant. The installation was very efficient and the chaps were clean and tidy. Worth every penny. We would highly recommend.
Poor air quality
The man from Envirovent suggested we needed a new replacement fan in the bathroom as the existing one was not efficient enough. I also requested 2 non mechanical air vents to be placed in the property. Envirovent did exactly what I asked for which has improved the air quality and fixed the problem. This was all at a fair price and the workmanship was good and they hoovered up any dust from the work. I would use them again.
Problem solved
We had problems with dampness, condensation, mould for some time and tried a number of remedies. We were given Envirovent as a possible problem solver. Without any hard sell from our initial enquiry we were shown a number of solutions to our problem, all within a reasonable price range. The work carried out by the Envirovent team was professional, with no mess. Highly recommend them as we saw results in a few days. The house is once again dry with no recurrence of previous problems.
Good job and efficient.
Envirovent did a good job from start to finish, good system seems to be working very well, thank you.
This system really does the job!
As we have an "L" shaped hall we had a "Dual" whole house ventilation system fitted. From the initial survey to installation, Envirovent did an excellent job. The installation was superb. Although ceiling holes had to be made the installer left our home spotless. You forget this system is actually there fairly quickly but make no mistake, the condensation problem has gone! Very pleased.
Endorsement reference - Great service
We had an extractor fan fitted in our kitchen due to condensation and mould and since fitted this problem has been cured. The workmen carried out the work to a very high standard and left the kitchen spotless. They arrived at stated arrival time and were polite and courteous while working in my property.
Endorsement reference -
Very good
Endorsement reference -
We had a Atmos loft unit and Cyclone bathroom fan installed. They were prompt with their services and the engineer arrived on time. He was professional, clean and gave good information on the equipment.
Endorsement reference - Damp and black mould issues
Ventilation System to help with damp issues. I had continued damp/black mould issues for years and everything I tried didn't help. I posted the job on My Builder website and Envirovent thankfully responded. The Agent - Julian, came to see me and explained fully what was happening in my home and suggested the Ventilation System. I had it installed on 12 January and bearing in mind the awful weather we've had already this year I have not had any sign of dampness/black mould showing through at all. The engineer was very professional and thorough and didn't leave a speck of dust behind him. I also suffer with Asthma and must admit to not using my inhaler anywhere near as much as I did before. I am so grateful to Envirovent.
