A* service and price. Highly recommended
They provided me with a good quote that was much cheaper then anyone else in SE London. Their surveyors were very professional and helpful in advising me for the best design for the front of my house. They did not even charge for any consultation fees and offered me a discount via their website.
I recommend them highly to all friends and family because of the price and also was amazed about the good quality of their fittings that it complimented the front of my home very well. I’ve been complimented frequently by my neighbours and family of this.
I don’t normally write reviews but in this instance, I believe that others would benefit from a great service offered to myself and family.
Manni provided a very good installation service. Very pleased with the end result. A+
