Whether you're dealing with tightly sealed glazing, bonded glass, or old stubborn mastic, using the right tools when replacing a window is what makes the difference between a smooth removal and a frustrating, messy job.
At GGR Glass, we supply specialist deglazing and glazing tools that professionals rely on every day. If you're planning to remove and replace a window, here’s what you actually need - and why.
The Deglazing Essentials
Start with the Deglazing Tool - a core piece of kit designed specifically for slicing through sealant. Its sturdy handle and razor-sharp blade give you the control and power needed to work around even the tightest beads. It’s ideal for general removal work, and if you’re a regular user, we stock both left-hand and right-hand replacement blades to keep you going without downtime.
For units that are bonded or glued into the frame, the Woods N4000 Deglazing Tool offers a much safer and more ergonomic solution. Combining a heavy-duty vacuum cup with a long pry bar, it lets you apply pressure without risking cracked glass or bent frames, perfect for large or awkward installations.
Supporting Tools to Finish the Job Right
Once the sealant’s cut, it’s often the small tools that make the biggest difference. A strong putty knife chisel is invaluable for scraping off old adhesive or mastic without gouging your frame. The glazing shovel is another unsung hero - its wide, angled edge helps tease the unit free while distributing force safely.
If you're resealing afterwards, don’t forget your finishing tools. We stock both mastic sealant finishers and angular sealant finishers to help smooth fresh joints for a neat, professional look. For longer or trickier runs, grab the Sealant Finisher Tool Set to cover multiple bead profiles in one go.
And of course, you’ll want a reliable caulking gun kit to apply fresh mastic or sealant with precision.
Safety First
Deglazing can be tough on both hands and eyes. For hand protection, the Neptune Kevlar™ Fingerless Gloves offer cut resistance while giving you full finger dexterity. Pair them with Checkmate CK112 Protective Glasses and keep your hands free with a Gambit eyeglass cord if you’re constantly in and out of tight spaces.
A Ready-Made Kit (If You Want It All)
If you’d rather skip the hassle of building your toolset piece by piece, the Glazing Tool Kit with Bag gives you a curated selection of essential tools in a single, easy-to-carry kit. Ideal for mobile jobs or teams needing multiple setups.
