    The company is not responsible for the incorrect installation or instruction of how to install the products supplied. All products supplied are guaranteed as follows from the date of order:

    • Aluminium Powder Coating- ten years. The paint finish applied to GO-70 series and all our other aluminium painted products is a polyester powder application. The powder coat only bonds to aluminium, so any thermal PVC sections separating aluminium sections may display overspray. This is normal and not a fault of the product.
    • All Hardware- ten years hardware manufacturer’s warranty.
    • Sealed units- five years glass manufacturer’s warranty.
    • Where installed by the company a one year labour warranty and a ten-year parts on warranty is provided. After this period, the customer is then responsible for the installation and any on-going maintenance.
  3. All doors have a standard weather rating and should not be fitted in an extremely exposed elevation or when adjacent to coastal areas. Claims against poor weather performance will not be accepted when installed outside the above guidelines.
  4. The warranty will be invalidated if the track is not kept free of debris not installed in line with the instructions supplied and if doors are not maintained in general.
  5. All drawings are viewed from the outside.
  6. No liability will be accepted for misinterpretation of drawings.
  7. Before ordering a door with an installation service attached you must first be advised by the company whether the company will undertake your order. Prior to any order with the installation package attached the customer will need to email digital pictures of the front and side access of the customers property. Plus images of the outside and inside view of where the customer's door is to be installed. The contract will not be binding unless the above guidelines are followed.
  8. The company does not install where no lintel is fitted. Please note if the customer advises a lintel is fitted and on survey this is shown not to be the case, the customer will be required to have a lintel installed by another contractor or the customer may cancel the order. The customer will be liable to a two hundred and fifty pounds charge to cover costs incurred.
  9. Aluminium doors can be installed above ground level, subject to location and wind loading and subject to written approval. The company does not knock out brickwork.
  10. Aluminium patio doors are to be fitted to the ground floor only, unless written approval is provided prior to purchase by the company. This will be subject to wind load and location.
  11. All folding doors are supplied only on the basis that they are to be located on the ground floor unless verified in writing by the company that they are suitable for your location and wind loading.
  12. Any structural calculations are the responsibility of the customer.
  13. All folding doors should have a suitable steel or catnic lintel fitted above the head of the frame. Timber lintels can only be used at the customers risk and no defect in relation to the performance of the folding door will be accepted when a timber lintel is used.
  14. All folding doors are to have no more or less than an eight to fifteen millimetre gap around the frame when installed. Outside these tolerances the performance of the door is not guaranteed and the warranty void. Additional packing with any other material to make up for any miss- measurement or excessive tolerances will also void the warranty.
  15. All folding doors can only be fitted into brickwork reveals and within the tolerances stated in condition twenty. Doors installed by the customer into any other aperture is at the customers own risk and not covered by the warranty.

  19. All toughened low emissivity coated glass units are subject to colour variations and variation in pattern. This may appear sometimes as a misting effect. This is natural and not deemed a fault.
  20. Low threshold doors do not offer the same weather performance, to the bottom of the door only, as standard rebated thresholds. You must therefore in the design and construction of the opening for your folding door allow for the removal of rain water, immediately in front of the threshold, to avoid water ingress. We recommend aco drainage systems for this application. Claims for water ingress will not be accepted when water management drainage channels are not used. The primary purpose of low threshold doors is level access. This is achieved by removing the rebated up stand. Air tightness to the bottom of the door is achieved by brush seals closing over the top of the low threshold which provides satisfactory draught proofing. However, if the doors are not correctly installed and aligned draughts may be experienced to the bottom of the door. Under extreme weather conditions the threshold area may be liable to draughts. This is normal and not a fault of the door. If you are concerned by water ingress or draughts, you should use the standard rebated threshold.
  21. Handle colours may vary in colour and chrome or sliver handles will always be a mix of silver and chrome lever or flat options. The company does not accept claims for variation in colour of handles supplied on any order. The company reserves the right to modify or change the design of all handles and hinges handle without notification.

When ordering any product from the company the customer agrees that they or their contracted installer will install and maintain all products as per the supplied instructions and have a good understanding of either carpentry, window and door installation or in the construction industry. Products can be installed and maintained by the customer on a do it your self-basis but the company does not offer any other support including telephone support other than the provided instructions. Upon any request for support via the telephone, e-mail or written formal request customers will be referred to or sent a copy of the original supplied instructions.
  23. All claims against the warranty must be made in writing to To ensure claims are recorded correctly no telephone claims will be accepted. You must provide your order number and full address. All claims will be responded to within three working days. We do not offer an emergency response and are not responsible for any financial or consequential loss.
  24. In the event of a claim against the warranty the customer may be requested to supply digital images to support their claim regardless if the door was supplied only or fully installed.
  25. Where goods are supplied only, all guarantees are for parts only no labour. All replacement parts are initially charged at cost up to a limit of two hundred pounds and refunded in full without question on return to the company. The company will arrange for the part to be uplifted by a courier on a week day basis only.
  26. When a door is installed by the company any relating claim on the labour warranty will be dealt with in a four-week period of the claim. At no time do the company offer an emergency service and are not responsible for any financial loss incurred due to the non-availability of a company service engineer.
  27. Site inspections at the specific request of the customer to ascertain any claim against the warranty or third-party issue in relation to products supplied will only be undertaken at the pre- paid fee of two hundred and fifty pounds for mainland England and Wales. If the claim against the warranty is valid the cost of the inspection will be fully refunded. The fee is fixed and not relevant to the distance from the company offices or time spent at site.
