We had two Velfac windows, a large picture window, two skylights and a set of 3 sliding minimal frame doors installed. Very happy with the products but the doors are still not fully operating - 2 years on. Pro's: - Nathan, our sales contact was very well informed and provided good advice at the early stages. - Contracts and payment points were all clear - Technical drawings clear - Products are good quality and feel - Bob was quick to attend when we had a big issue after install - Good value Con's: - Builders left to interpret the window requirements - a video walkthrough together would have instilled more confidence to both parties. Even though all worked out fine. - Sliding door product is not operating due to damage arising from previous fixes. Still waiting a fix; communictions ongoing.
Super smooth experience! Everyone MFP were easy and honest to work with. The fitting team lead by Jason did an exceptional job craning our glass roof up and over the house! The glass itself is beautiful and was measured to perfection. Top work thank you all!
Absolutely delighted with our recent purchase of sliding doors for our new orangery, part of a major renovation of our home. The quality is top-notch, and the sleek design will perfectly complement our modern kitchen and frame the amazing views we have. The door’s sturdy construction and beautiful minimalist finish add a touch of elegance to the space. Highly recommend this product to anyone looking to enhance their home with stylish and functional sliding doors.
