We have just made our 2nd order from Modern UPVC because we were so impressed with our aluminium bi-folds and windows. The online creation tool is great, I really like how we could see how much it was to add different specifications instantly. Delivery was exactly as specified and we appreciated the week advance notification of delivery day so we could book the time off work. It was also free so another reason we are so impressed. We also had a few questions when installing them ourselves, we emailed and (even during lockdown) we got a response within 24 hours! So we just bought a composite door and we are confident our order will be as perfect as before.
