Re-Glazing in Janesville
Over time, greenhouses in Janesville endure wear and tear from weather, UV exposure, and daily use. Panels can become cracked, discolored, or inefficient, reducing your greenhouse’s ability to maintain temperature and maximize plant growth. At Quality Structures, we specialize in professional greenhouse re-glazing to restore clarity, improve insulation, and extend the life of your structure.
Why Invest in Greenhouse Re-Glazing?
If your greenhouse isn’t holding temperature as efficiently as before or your panels appear cloudy and worn, it may be time for an upgrade. Replacing aging glazing materials enhances light transmission, energy efficiency, and overall performance, helping you maintain a productive growing space year-round.
Benefits of Greenhouse Re-Glazing
Improved Light Transmission: Clearer panels allow more sunlight to reach your plants, boosting photosynthesis and growth.
Better Energy Efficiency: Enhanced insulation reduces heating costs and improves temperature regulation.
Extended Greenhouse Life: Regular maintenance and re-glazing add years to your structure, protecting your investment.
Enhanced Appearance: A refreshed look improves the aesthetic appeal, especially for retail and garden center greenhouses.
When Does It Make Sense to Re-Glaze a Greenhouse?
If your greenhouse is over five years old, has visible cracks or yellowing, or struggles with maintaining heat, re-glazing could be the perfect solution. Higher energy bills, decreased plant performance, or excessive condensation buildup are also signs that it’s time to replace outdated glazing materials.

I highly recommend Quality Structures! We suffered softball-sized hail damage to the roof of our Nexus 30×100 roof and needed a re-cover! Communication with this company is outstanding. I received a fair-priced bid very quickly. They put me on their schedule and were in contact with me as material arrived and as the scheduled work date got closer. They are diligent, professional, courteous and hard-working. Their work ethic and construction ability is excellent. This is the kind of crew you want to have on your property. Give them a call!!

Jeffery and his team were great to work with. We had broken high tunnel sides and Jeffrey was able to come out with in a couple days to fix them. They communicated well and did the job quickly and efficiently.
