Purchased several very large Ally sliding Doors for a New Build Home. Company were professional, helpful and friendly through out. Dan remained at end of phone for any Pre Fit Queries we had. A pre site visit enabled Chippies it talk through needs . Installers were also very organised , friendly and professional. And all work was checked by a senior member after work was completed. Although these doors were a considered purchase , their price point compares very well with other possibly more prominent companies. But the quality is top notch. Thanks Ultraline Team.
