Found, not guessed

A hidden leak, found in one visit

A thermal imaging survey picked up a cold spot in the ceiling. Instead of opening up large areas, we cut out one small section at exactly that point and found the leak straight away.

How our leak detection works

Before & after

The difference professional remediation makes

Painting over a stain or spraying mould only hides the problem. We deal with the moisture behind it, so the result lasts.

  • ★★★★★Leak & insurance quote
    We had a leak and our insurance asked us to get 3 quotes. I must say Moisturefix has been the best by a mile. David who attended was very knowledgeable, answered all our questions and we had the report and quote for our insurance company the next day. Recommended all the way, thank you!

  • ★★★★★Mould survey & removal
    I had had green mould appearing at the bottom of my bedroom wall, looked online and found Moisturefix. Their technician was great and informative. He carried out a survey and advised what the cause was. Pleasantly surprised to receive the report the same day. All the mould was also cleaned and it came out great. Highly recommended!

  • ★★★★★Roof leak & drying
    We had a roof leak that affected one of our bedrooms. MoistureFix came out to survey the damage, removed the affected ceiling and set up drying equipment. They explained what needed to be done and kept us informed throughout. We were pleased with how the work was handled and would recommend them.

  • ★★★★★Flooded basement
    What an amazing service! Our basement got flooded and I thought everything down there was ruined forever. They brought in these massive dehumidifiers and got to work immediately. They handled the moisture report for the insurance for us too, which took so much stress off my plate. It's completely dry now. So, so happy with the result!

  • ★★★★★Leak & strip-out
    Following a leak from our bathroom, we contacted Moisturefix for help with the water damage. David came out late in the evening to install dehumidifiers and then carried out all the necessary strip out to allow our flat to dry properly. From the initial visit through to completion, everything was handled professionally and the work was carried out to a great standard. Really pleased with the service and would definitely recommend them!

FAQs

Questions we're often asked

Do you offer emergency call-outs?

Yes. We offer 24/7 emergency call-outs for leaks, escape of water and flooding across London and surrounding counties. Call us on 020 8050 8678 and we'll prioritise getting someone to you.

Is the quote really free?

Yes, for jobs we can price from photos. Call or WhatsApp us with a description and a few photos and we'll give you a free, no-obligation quote. If the problem needs a survey to diagnose properly, such as a hidden leak or unexplained damp, we'll tell you upfront and offer one at competitive rates.

Can you help with my insurance claim?

We prepare comprehensive reports for insurance claims, covering the cause and extent of the damage, moisture readings, photographs and drying records, so your insurer or loss adjuster has the evidence they need.

Do you repair leaks?

We find leaks and dry out the damage. We're partnered with a selection of trusted plumbers, so once a leak is located we can usually give you a quote for the repair on the spot.

Will mould come back after treatment?

Mould returns when the moisture causing it isn't dealt with. That's why we always find the cause first, whether that's a leak, condensation or poor ventilation, then treat the mould and advise you on preventing it.

Can I just hire a dehumidifier?

Yes. We hire out industrial dehumidifiers and air movers for homes, landlords, builders and commercial sites. Get in touch and we'll recommend the right equipment for the space.
