Written by the company
In 1992, MG Window Systems kicked off its journey in Northampton as a window manufacturing venture, founded by the dynamic duo of Mitch Brown and Gary Frost, former NAC employees. The initial factory on Rothersthorpe Avenue Industrial Estate remains the epicenter of their operations. Mitch handled manufacturing, and Gary mastered installations, forming a powerhouse team with stellar industry reputations. The early years saw MG crafting windows in limited profiles and colors, primarily with Marshall Tufflex. Fast forward to 2004, the landscape changed—extrusions ceased, and options multiplied. Rather than crumble under the challenge, Gary and Mitch sought alternatives. After a flirtation with in-house production, they struck gold with Glazerite and the Veka system. As the business evolved, Mitch bid adieu in 2007, leaving Gary at the helm. Enter Mark Russell in 2009, injecting carpentry and building expertise into the mix. The MG Windows narrative took an exciting turn—expanding into small extensions, conservatories, and substantial aluminum commercial projects. Their commitment to excellence earned them approval from Trading Standards, a nod from WHICH, and membership in the Independent Network Veka. Gary retired in 2018, making way for Mark's wife, Emma, to rejuvenate the office and instil new processes. Enter 2023—Matt Munns, once Mark's apprentice, steps into the spotlight, acquiring MG Windows. They're not just new owners; they're catalysts for change. The trio introduced cutting-edge operating systems, propelling efficiency and customer satisfaction to new heights. This isn't just a takeover; it's a saga of growth and innovation. MG Window Systems is poised for an exhilarating future, crafting quality windows, and delivering stellar customer experiences for the next 30 years. The adventure continues!

Outstanding Quality Product and Aftercare Service
I couldn't recommend MG Windows highly enough. I bought my bi-folding doors and front door and porch window from them 7 years ago and am delighted with the quality of them. However, what prompted me to leave this review is being even more pleased with the level of aftercare I have received - even after 7 years! I had to call them this morning as my locking mechanism failed on my front door (which can happen) leaving us with a door that wouldn't lock and Noel was there within the hour and had replaced the handle, barrel and locking mechanism all within 30 minutes of his arrival. Outstanding thank you so much!

Very pleased with my patio door
Very pleased with my patio door. Fitters did a brilliant job, had some electric wiring which was covered very professionally (much better than it was previously). Place left very clean and all looking great. Would certainly recommend MG windows to friends and neighbours.

WHAT A TEAM…
Absolutely fantastic team from start to finish! Communicated everything from the beginning and were incredibly fast at ordering, delivering and installing. The installation process was so quick with zero mess and they literally completed a barn conversion in 2-3 days. Lovely blokes too and really polite and helpful. The product is superb and we are totally delighted with the transformation. Thanks so much MG Windows - total pleasure to work with.

Great Team
I was given a detailed quote from Matt and I knew exactly what I was purchasing. Great communication from the admin team, via emails. Joe the fitter was so friendly, professional and nothing was to much bother. Took his time and a great finish to the work. I had an imperfection on a glass panel but got it replaced with no bother! Thanks MG TEAM. Highly recommended.
