I would highly recommend New Wave as a company, we ordered 3 sets of doors from them last year, we dealt with a very helpful lady in sales to start with who answered our original queries, our builders then had some questions so the sales lady put the installation department in contact with them and everything thing was sorted within a couple of days, our doors were installed 2 weeks ago, all be it a little late, but I can understand this given the current climate.We could not be happier with our doors and we are so glad we made the decision to go with New Wave rather bifolds.
