As an architect, I’ve worked with many UPVC and aluminium window suppliers, but my experience with M/s P Jha & Sons has been outstanding. Their product quality, finishing, and overall service are good. I’ve used their windows and doors for several of my client projects, and the results have always been excellent — smooth operation, great look, and lasting performance. The team is very professional, responsive, and always ready to support site requirements on time. Really happy to have a reliable supplier like them who understands design needs and delivers what they promise. P J Associates C-5, Rajouri Garden, N.D. Paramjeet Singh Architect
