What our customers say about our Windows & Doors...

  • Martindale Windows recently replaced all the windows at my house (18 Windows, 2 doors, Patio Door & French Door). From initial communication through to sign off I have been very impressed.
    I found them to be very professional, approachable & competitively priced without skimping on quality.
    The fitters were clean, tidy, polite and careful – treating my house like a home, not a building site.
    We are very glad that we chose Martindale and would recommend them in a Heartbeat.

  • I have been very impressed with Martindale Windows.
    I required replacement double glazed windows and this company was recommended by my son. I have not been disappointed. Their products are very high quality and their prices very competitive. Thank you to Russ, Joe, Richard and Jane for such great customer service, my windows look great! and I will definitely be back in the future as a customer.

    I wanted to replace my front door but unsure upvc or composite door. I spoke to several different companies. And decided to buy local from Martindale Windows. Father & Son experience shared their knowledge on the difference between the two doors. I settle with a Composite door. The friendly receptionist rang me to confirm a fitting date. The fitters turned up and introduces themselves, and fitted the top quality door. I am one happy customer.
