Warranty FAQs

Does your warranty only cover for deterioration of the product?
  • No, our warranties cover you for much more than product deterioration.
  • Product deterioration warranties offer little protection for homeowners, and it can be challenging to prove.
  • Instead, we remove the uncertainty for you. Our warranties go far beyond product deterioration and cover the repair against eventualities that are beyond your control and ours, which is why our warranties are industry-leading.
What exactly will my warranty cover?
  • Repair failure beyond our control caused by; burst pipes and drains, reactive clay subsidence, soil washout, vibrations from nearby construction, subsidence caused by vegetation growth, and additional load from a single story extension.
  • Repair failure caused by material shrinkage, deterioration, corrosion, rot, breakage.
  • Faulty installation or poor workmanship.
Can I transfer the warranty?
  • Yes, there is a small admin fee, and you must give the new owners the original quote, repair detail, and a copy of the invoice to ensure they fully understand the work carried out by us.
What happens if I need to claim my warranty?
  • In the rare case you call us back, we will return to assess the original work and monitor for a short time to establish what is going on with your home and pinpoint any problems. If our initial repairs fail, we will return once to ensure your home is repaired as promised.
How long will my warranty last?
  • All Buildfix warranties last for ten years and begin the instant works are complete.
