About Us

Windowstein is an award winning Window and Facade fabricator, based out of Chennai, India. With an experience of over three decades in the industry, nobody knows windows and facades like we do! We partner with some of the best uPVC and aluminium profile manufacturers to bring you myriad solutions in the world of windows and facades. During the course of its journey, the Windowstein group has completed over 400 projects successfully. With this, we are proud to have played a part in changing the skylines of Chennai. Proof of our patronage lies in the fact that many of our customers have been associated with us for over 25 years for which we are ever grateful.

Windowstein started as Aluminium Combines in the year 1990 with a team of four employees led by our co-founder and mentor Rakesh Mohta. The primary focus of Aluminium Combines was Aluminium windows and facade fenestration. In 2012 we added the uPVC window business to our portfolio under the name – Mohta Enterprises Pvt. Ltd. Through this journey we had the opportunity of working with some of the finest architects, builders, consultants and interior designers in the country. This exposed us to great knowledge and technical understanding which helped us to rise to many challenges and make us what we are today. In 2017 to have a stronger identity for ourselves we merged the aluminium fenestration and uPVC window business into one company and created – brand ‘Windowstein’. Today Windowstein has over 40 employees as part of its family and employs an equal number of workers on contract.

We strongly believe that learning is a continuous process and hence we constantly look to update ourselves with the latest systems, processes and technology. While we have worked in several other cities in India from Indore in central India to Rameswaram down south, it is our constant endeavour to spread our wings and establish brand ‘Windowstein’ further.

At Windowstein, we always strive to do more so that our customers get more. We take our after sales service very seriously and it is in fact one of the things that sets us apart from our competitors. We take pride in what we do and it is this sense that we inculcate in our employees too.
