Low-Energy Double Glazing Upgrades for Hull & East Yorkshire Homes

MJS Windows are a family-run company based in Hull with over 20 years’ experience supplying, fitting and upgrading windows across East Yorkshire. We specialise in energy-efficient window solutions that help reduce heat loss, improve comfort and lower domestic fuel bills, all installed by our experienced local team.

We offer A-rated double glazing and options such as low-E glass, argon gas filled sealed units and thermally efficient aluminium or uPVC frames. These features work together to improve insulation and reduce condensation, while maintaining clear sightlines and attractive finishes to suit both modern and period homes.

Upgrading existing sealed units or replacing whole frames can make a real difference to a home’s energy performance. Our surveyors will recommend the most cost-effective solution, whether that’s a sealed-unit upgrade, new A-rated windows or a higher-spec option such as triple glazing, and we provide clear guidance on likely energy savings and payback.

Our fitters install every window to industry best practice, using trusted hardware and high-quality units to ensure long-lasting performance. Work is completed neatly and with minimal disruption, and we back installations with guarantees and dependable aftercare so you can be confident in both the product and workmanship.

If you’re interested in reducing heat loss and improving comfort, contact MJS Windows for a free, no-obligation quotation. Book a home survey and our local team will assess your current glazing, explain the best upgrade options and provide a clear, competitive price.

What can I say? Exceptional service from start to finish! The pricing was incredibly competitive, and the qualit, Simply outstanding! I had my Bay Window, Bathroom, Kitchen, and three Bedroom windows installed, and each one was completed to an exceptional standard. I was so impressed, I even added a door after the original windows were done. Highly recommend!

Turns up when he says. Does a good job. Even after several months a minor problem occurred and he came back and sorted the problem free of charge. Not often service like this exists anymore.
Janp Thomas
Excellent work in replacing a misted double glazed window panel in our bay window. Excellent customer service and we would have no hesitation in using the company again and in recommending them to others.
Rob Lawrence
Fantastic result and great price. Mark and his team fitted new white pvc windows to the front of our house which were previously in brown wooden frames. This has completely changed the overall look of our house and we are very pleased!
Would highly recommend, thank you!
