Rated 5 out of 5 stars

Deb and Dave

We wanted a juliete balcony and a wider lounge patio doors. A very messy job.
From start to finish the ⁰men on the job were fantastic
and cleaned up every day.It took 5 men to lift the glass balcony up on a lift with scaffold as it was over 130kgs.
They had never done such a large balcony before.
It looks fantastic.
The plasterer and electrician were brilliant and the finish is ready for the decorator.
I cannot fault their workmanship.

Beyond dreadful

Mere Green/ Sutton Coldfield. Four Oaks Location.

Beyond dreadful. Worst after sales care experience not only from a window company but any business.

I've has three previous experiences with upvc windows with other companies. On each occasion all post fitting issues were dealt with professionally, competently, without fuss, protest or attitude. JMI are the Exact Opposite.

Windows supplied appear to my eyes to be very low quality, poorly manufactured with obvious defects. After sales inspection a complete disgrace. They just don't care and left me stunned and insulted.

Site visit to inspect resulted in being told that's just how it comes from the factory. Imagine buying a new kitchen and having the supplier tell you that. Its ridiculous. Multiple issues.

Very pricey compared to other suppliers. If you're going to charge 20% more than the rest, at least ensure you offer a superior service not a Worse one.

I now have two choices. Take JMI to the civil courts or dump the offending windows, start again and write off thousands of pounds.

I utterly condemn this company.

Don't sign the contract. Walk away and go elsewhere
