⚠️ WARNING TO ALL CUSTOMERS — PLEASE READ BEFORE USING M3 FLOODTEC
I had flood defence doors installed by M3 Floodtec in November 2022 at a cost of over £6,000. Within 3 years the door began falling apart, with the beading separating and the panel becoming loose within the frame.
⚠️ The Initial Response:
When I contacted M3 Floodtec with video evidence of the issues, rather than acknowledging the problem they offered to attend and fix it for £500 + VAT, with an additional minimum charge of £204.50 + VAT if further issues were found. They cited the expired 12 month warranty as their reason for charging — despite the Consumer Rights Act 2015 giving consumers up to 6 years to bring a claim for substandard goods.
⚠️ The Independent Inspection:
I obtained an independent professional inspection which identified two clear installation defects — the glazing gasket had not been installed and the door had not been correctly toe and heeled. The inspector confirmed in writing that both defects were installation issues, not wear and tear or misuse.
⚠️ Their Engineer's Visit:
After significant pressure, M3 Floodtec arranged a visit. Their engineer applied superglue to the beading as a temporary fix and verbally suggested the door may have been affected by direct sunlight due to its black rosewood colour. No permanent works were carried out. Their own Maintenance Report Form confirmed corrective action was required and a follow up visit was necessary.
⚠️ The Misuse Claim:
Following the visit, M3 Floodtec concluded the damage was caused by misuse — despite their own engineer's report making no mention of misuse whatsoever. They then quoted £1,921.50 + VAT for a replacement panel and slab. This is on top of the original £6,197.88 installation cost.
⚠️ The FENSA Issue:
I also discovered that a glazed door installed at the same time — containing more than 50% glass — was never registered under Building Regulations as legally required. When challenged, M3 Floodtec failed to register it within the timeframe requested. A formal complaint has been raised with FENSA regarding this failure.
⚠️ The Warranty Extension:
It is also worth noting that M3 Floodtec quoted £466.80 per year for an annual maintenance inspection as the only way to extend the warranty beyond the initial 12 months. No repairs are included in this charge — any works identified during the inspection are quoted separately at additional cost.
⚠️ Where Things Stand
Formal complaints have been filed with FENSA, the Consumer Protection Association, and Trading Standards via Citizens Advice. The matter is now proceeding to the Small Claims Court.
⚠️ Important message to anyone reading this:
If you are considering using M3 Floodtec, please think very carefully and make sure you fully understand the warranty terms, maintenance costs, and your rights before signing anything.
If you have already had doors installed by M3 Floodtec and are experiencing issues, please take these steps:
One — Check whether your installation has been registered with FENSA at fensa.org.uk. If your door contains more than 50% glass and has not been registered, this may be a breach of Building Regulations. Contact FENSA directly to raise a formal complaint.
Two — Contact Citizens Advice on 0808 223 1133. Regardless of whether your warranty has expired, you may still have rights under the Consumer Rights Act 2015. A product that fails prematurely may not be of satisfactory quality and you have up to 6 years to bring a claim in England and Wales.
Three — Get an independent inspection before agreeing to any chargeable works. An independent report can confirm whether issues are installation defects or genuine wear and tear.
Do not be put off by expired warranties or claims of misuse without evidence — your statutory rights exist independently of any warranty a company provides.
