Understanding mould
Unless you've had a leak or flood damage, there's a good chance the mould in your home is the result of condensation: showering, cooking and drying clothes, combined with poor ventilation. Condensation is behind 80 to 85% of household mould.
Wiping mould down, even with bleach, can make the problem worse by releasing more spores into the air. Bleach takes the colour out of mould, so it looks gone while the mould underneath is still alive.
Warm, moist air from showering, cooking and drying clothes, with poor ventilation, reaches the cold outside wall. There it condenses, and mould follows.
Our process
There is no silver bullet for mould. Every home is different, and every mould problem comes from its own mix of circumstances. So we work in four steps.
Our technicians survey your property with professional diagnostic tools to find the likely cause of the mould and any visible growth. The aim is a clear picture of why the problem exists and, crucially, what can be done. Air tests, analysed by a laboratory, show the type and level of mould in your air.

Your treatment plan factors in the balance of humidity, air temperature, surface temperature, structural integrity, air pressure and ventilation in your home. Where condensation is the cause, we control the conditions. Where there is an active leak, we diagnose it and refer the repair to the right trade.
CHECK WITH ELLIS/PHIL: condensation control is part of the serviceWe physically remove visible mould growth. Where water has damaged materials, we strip them out and dry the structure. Then we treat the whole home with our dry fog and apply EverPURE, a durable antimicrobial layer that helps resist regrowth.

With our full PureHome treatment, we test your air before and after treatment, with an outdoor air sample as the control. The samples go to an independent accredited laboratory, and we give you the results in writing.

The technology
Our patented dry fog reduces mould contamination and helps inhibit regrowth, and every treatment plan is built around your home. VERIFY: patent status
Our patented fogger turns our sterilant, InstaPURE, into droplets of roughly 7.5 microns, so small that the fog comes out dry. Because it can't condense on surfaces, it stays in the air and reduces airborne spores.
We treat in a sealed room under positive air pressure. The fog reaches every exposed surface the air touches, into folds and recesses a cloth can't, and stays there for the full dwell time before the room is cleared. Unlike a spray or wipe that only hits what you can reach, it treats surface and airborne mould in one pass.
Afterwards, the sterilant breaks down to acetic acid (vinegar), water and oxygen and is ventilated out, with no lasting disinfectant residue. Every treatment is applied under a COSHH assessment by trained technicians in PPE.

Strongly recommend Pure Maintenance. Everyone from sales to technician were very friendly, helpful and efficient. Every step in the process was explained to me in detail and all findings were reported back to me quickly. Ever since the treatment my home feels so much fresher brighter - just wish I'd have done it sooner!
I've had Joe from Pure Maintenance at my property a couple of times and he has been fantastic. Always very clear about exactly what is going to happen and very respectful of everything. The company offer a great service and I would throughly recommend them. Good value for the treatment provided
Yes. Once it's been aired out, your treated home is safe to walk back into, typically the same day.
The fog's droplets are roughly 7.5 microns, so it reaches every exposed surface the air touches. Where there's a known problem inside a wall void, and with your agreement, we can make small, discreet access points and treat the cavity directly.
Where water has caused damage, we strip out and dry the affected materials and treat the home. The active leak itself we diagnose and refer to the right trade.
With PureHome, your technician takes three air samples: one before treatment, one after and one outdoors as a control. An independent accredited laboratory with no affiliation to any mould testing or remediation company analyses them, and we send you the results in an easy-to-read dashboard.
CHECK WITH ELLIS/PHIL: PureHome onlyWith PureHome, if visible mould reappears within 12 months, we come back and re-treat, as long as the ventilation plan has been followed and any flagged leak has been repaired. Where there are major water issues such as active leaks, EverPURE gives about 90 days of protection.
