Testimonials

Customer testimonials

“Fabulous in every way! We got quite a few quotes for new windows/doors and the products & quotes varied greatly. In the end we went with Ultimate Design because they offered a top quality product, they were very professional and presented us with a very appealing quote saving us thousands of $$$$.”
Shelley H.
“Thank you Fordy for your service and communication over the past 2 years. We had all our windows and sliding doors replaced with double glaze. I even got my dream black mirrored front door and smart lock. Hubby is still recovering from the cost of that door! Anyway, I will continue recommending your company!”
Deidre L.
“We were very impressed with the design advice for our new conservatory and found it easy to envisage how it would look. Construction was very quick, surprising our friends who commented "it's in already?" The completed project complements the existing layout and looks as if it was installed as part of the house rather than as an addition.”
Garry H.
"Love my new door. Replaced my rotting wooden door with a dodgy lock with a sleek, super low maintenance aluminium set. It was an easy process from quote to installation. Hannah nailed the colours and the builders were a pleasure to have on site. Highly recommend these guys for similar renovation work."
Lesley Isaac
"Ultimate Design & Renovation Ltd did an amazing job! Hannah was fantastic to deal with—professional, friendly, and always helpful. We absolutely love our new doors; the quality and craftsmanship are outstanding. Highly recommend their services!"
