“We used Marlin for windows and traditional Steel Replacement doors and screens using Alitherm Heritage products on our recent self-build project. Marlin are not local to us but provided an excellent service from quotation, advice, redesigns and with very detailed communication throughout. Would highly recommend.”

“The product looks amazing too… I suppose the windows might be much the same elsewhere & maybe even of similar price or cheaper, but the customer support, reliability, professionalism & interest at Marlin is second to none.
I honestly think it’s a rarity these days to come across a company with values like Marlin so 5*s well-deserved.”
