Duration Windows

2 x bifold doors remains to be seen 1 x slimline rooflight never fitted as it proved impossible to fit Sad state of affairs.... Took delivery of 2 Bi-fold doors from Duration which appear to be working fine but having read the reviews since who knows for how long Unfortunately we can not say the same for the " SLIMLINE ROOF SYSTEM" which was recommended by Duration when we took the time to travel 200 miles to Canvey Island for a face to face meeting where they could look at our architects drawings and understand our requirement [ in order to avoid what turned out to be the situation we did have ] The recommended product by the manager at the Duration "Grand Designs Showroom" was a "Slimline roof light ". This was despite the fact that our roof was a 37 degree pitch . We pointed this out and were assured that although this was referred to as a "Flat Roof" product it could also be used on pitched roofs. We ordered, we took delivery, and then the fun began. first question ..."where is the flashing kit ?" Duration said " we do not offer a flashing kit with this product " . next question ...."So what are we to do ?" Duration said "you need to find someone to make a flashing" We then spent 4 weeks trawling every flashing manufacturer for miles around all of whom declined to quote as they said " You have been sold the wrong product" ..."We could not guarantee it not leaking if we try to flash it " Having left the scaffold up around the roof for 4 weeks longer than needed [waiting for a solution to this problem ]. We eventually considered all the options knowing that there was no fitting company who would consider it. We now knew that Velux offer a similar product in a similar size WITH a flashing kit at a considerably lesser cost. There was no choice we ordered the Velux and had it fitted 2 days later successfully. We wrote to Duration to say that reluctantly, after 4 weeks of exchanging e mails on a regular basis unsuccessfully with their "customer services", We had no choice but to take an alternative product to satisfy this need and we would reluctantly have to ask them to refund the window which was impractical and collect it from site for return [ inasmuch as it clearly could not be fitted satisfactorily and was costing considerably indirect costs by keeping the scaffold up and delaying the entire job site ] Unfortunately Duration did not see it the same way and We received a telephone call from a manager who stated that " It doesn't work like that" - "there is no refund to be made " ..."YOU made the wrong choice of product " N B We had made no suggestion to recover the considerable extra costs incurred by the failure of this product to be successfully fitted. We had merely asked that they collect it and refund the original cost paid after 4 weeks of endeavour to find a solution as to how it could be fitted successfully.. Not a happy ending ! Anyone want to buy a useless Duration Flat roof window 1.5 m x 1 m - cost £ 700 - yours for £ 50 buyer collect ? Don't get caught the same way. Try Velux ...less cost ...no problem to Flash... and just less hassle. Duration's Bi-fold doors are fine but, certainly on the Slimline roof product , their after sales acknowledgement of responsibility is to say the least lacking . Very Dissatisfied or Cheshire
