Mould survey and fogging prices
Know what you'll pay before anything is booked. Every price includes your written report or treatment, and your quote is free.

In short
Simply Filtered prices its mould surveys, window film surveys, water damage assessment reports and antimicrobial fogging by the property, and gives a free quote with the exact price before anything is booked. These are paid, independent assessments rather than sales visits: Simply Filtered doesn't sell building or ventilation work, so the price of the survey is the only thing it charges you for.

Why you pay for the survey
A survey you pay for is a survey with nothing else to sell. Building, repair and ventilation installation aren't part of what we do, so your report recommends what your home needs, not what earns a bigger job.
If your plan does need work, you can take the report to your own contractor, or ask for an introduction to a trusted third party. There's no obligation either way.
Questions
Questions about prices
Is the quote free?
Yes. Send the form and you get the exact price and what's included, free. Nothing is booked until you're happy to go ahead.
What affects the price?
Mostly the size of your home and how much of it needs looking at: the number of rooms for a mould survey, areas for fogging, windows for a window film survey, and how far the water reached after a leak or flood.
Is fogging covered by home insurance?
Fogging is often covered as part of a home insurance claim. Check with your insurer.
Will I be asked to pay for anything else?
Not by us. Your price covers the survey and report, or the fogging treatment. If your report recommends work, it's quoted separately by whoever you choose to do it.
