WHAT OUR CLIENTS SAY...

Ordered a new bi-fold door and had it installed by the EcoDemo team. The door unit looks great and is high quality so far as I can tell. The install work was quick and professional, and the team super friendly. The new door works perfectly, really happy with the outcome. Highly recommend.

Cormac McCullough

I purchased a sliding door from EcoDemo and installed it to my house. The job is done perfectly! I'm happy with their product, price, and services. Zahira is very responsive and has treated me nicely. Zubeer, the installer, did a great job and he is also a very nice guy. Thank you, Zahira and Zubeer :)

Fantastic company to deal with. Seun and his team are top notch. Nothing is too much and no question is too silly for them. Seun has gone above and beyond to answer questions, write up comprehensive quotes, adjust them time and time again, and just in general has been a pleasure to deal with. Customer service second to none. This is topped off by a beautiful set of products, their windows and doors are impressive both is design and quality, at the most affordable prices. A huge tick from us and would recommend to everyone! Thanks team.
