Help to prevent condensation and mould in your Middlesbrough home, diagnosed in-person by a local expert.
If you're waking up to streaming windows, patches of moisture on the walls, or mould appearing in corners and behind furniture, you're dealing with one of the most common problems in Middlesbrough homes. Much of the area's housing is exactly the type prone to condensation: older terraces, post war and former local authority semis, and the many bungalows found across Acklam, Marton, Nunthorpe, Ormesby and out toward Guisborough.
These homes were built to hold heat in rather than let moisture out, and as they've been improved over the years with double glazing, draught-proofing and added insulation, the moisture from everyday life has fewer ways to escape. It settles on the coldest surfaces, and that's when condensation and mould take hold.
Bungalows are particularly affected. With all the living space on a single level, moisture from cooking, washing, drying clothes and simply breathing builds up quickly, and without adequate airflow it has nowhere to go. Condensation can look straightforward but its cause is often less obvious. What works in one home can make things worse in another, which is why the right diagnosis matters before anything else.
The real causes are usually hidden: where moisture is being produced, how air moves through your property, where cold spots form, and how the building was constructed. Reading a Middlesbrough property correctly takes experience, and that experience is what you get with every survey.
Every free survey is carried out in person by a local specialist. It's never outsourced and never guessed at remotely. The whole team is trained directly alongside envirovent's flagship head office technical team, so the expertise that diagnoses your home is the same high standard on every visit.
During your survey, the specialist takes humidity readings, identifies the underlying cause, and recommends the specific solution your property needs, with no obligation. It's a considered diagnosis of your actual home, not a one-size-fits-all answer.

If you have an issue with condensation, mould build up or ventilation issues then envirovent are the company to go to. I have been using their services for 10 years and have had a number of my rental properties surveyed by envirovent where they come up with a solution to eradicate mould issues by creating extra ventilation methods or better ventilation.
Landlord in Croydon
We have suffered condensation mould and running water on our windows for over 40 years. We have tried numerous products to remedy this and never really succeeded. In a matter of days of having this system fitted our problems have been solved. Really pleased. Great service, a brilliant system couldn’t ask for anymore.
Homeowner
We are a returning customer to envirovent. We know their systems work to reduce/remove problems with condensation & mould. We would highly recommend their products & all aspects of their service from initial enquiry, through to installation.

Damp and mould in rental property is increasingly becoming a compliance priority, not just a maintenance issue. Awaab's Law came into force for social housing in England in October 2025, introducing strict timeframes for addressing damp and mould, and the direction of travel for private landlords is clear, with the government having stated its intention to extend similar duties to the private rented sector.
Getting the right ventilation in place now is far more straightforward than dealing with a complaint later. Your local specialist works with private landlords across Middlesbrough to assess properties, identify the cause of recurring condensation, and recommend the right long-term solution, protecting both your tenants and the value of your property.
Once you request a free survey*, one of our local ventilation specialists will get in touch to speak to you and discuss your concerns. If ventilation can provide a long term solution, we’ll arrange a convenient time to visit your home.

Frequently Asked Questions
You often can't tell just by looking. The same black mould can be caused by surface condensation, a ventilation problem, a building defect, or a combination, and each needs a different response. That's exactly what the free home survey is for: an in-person assessment and humidity readings to pinpoint the real cause before any money is spent.
A trained local specialist, in person, every time. The whole team is trained directly alongside envirovent's head office technical team, so you get the same standard of expert diagnosis on every visit. It's never done remotely
It depends entirely on what your property needs, which is why an expert survey comes first. The survey itself is free and carries no obligation. You'll get a clear recommendation and a price for the right solution.
No. The survey is completely free and there's no obligation to go ahead. It's the best first step whether or not you choose to go further.
Awaab's Law already sets strict damp and mould duties for social housing in England, Scotland's version is confirmed to cover private rentals from October 2026, and the UK government has signalled it intends to bring similar duties to private rentals in England. The direction is clear, so getting ahead of it now is the sensible move. Your local specialist works with private landlords to assess properties and resolve damp and mould at the source.
They're especially prone to it. With all the living space on a single level, moisture from cooking, washing, drying clothes and breathing builds up quickly, and without the right airflow it settles on cold surfaces as condensation. Over time that leads to damp and black mould. They're among the most common property types we're called to, and getting the airflow right throughout the home is what helps to prevent it.
