When you search for glass window repair near me, you are usually looking for a fast, reliable solution. Maybe you have a cracked pane, loose glass, old putty falling away, or a window that no longer seals properly.
While some window repairs may look simple from the outside, reglazing a window requires care, patience and the right technique. One of the most important steps is removing the old putty properly before new glass or fresh glazing putty is installed.
We often see window repairs where old, brittle putty has been left behind, causing poor seals, leaks, draughts and an untidy finish. If you are planning a DIY repair or want to understand what a professional glazier should be doing, here is why proper putty removal matters.
What Is Window Reglazing?
Window reglazing is the process of removing old or damaged glass, cleaning and preparing the frame, and installing new glass or resealing the existing pane.
This is commonly needed when:
- A windowpane is cracked or broken
- The glass is loose in the frame
- Old putty is dry, brittle or falling out
- Water is getting through the window frame
- The window no longer seals properly
- A property needs general glass maintenance
For Auckland homes and commercial properties, proper reglazing can help improve safety, weather protection, insulation and the overall appearance of the window.
Why Proper Putty Removal Is Important
Old glazing putty plays an important role in holding glass securely in place and sealing the edge of the window. Over time, putty can dry out, crack, shrink or separate from the frame.
If old putty is not removed correctly before reglazing, the new seal may not bond properly. This can lead to:
- Water leaks around the glass
- Draughts and poor insulation
- Loose or rattling glass
- A messy finish
- Repeat repairs sooner than expected
- Further damage to the frame
A proper glass window repair should never involve forcing new glass into an unprepared frame. The frame needs to be cleaned, checked and prepared so the new glazing can last.
Step by Step: How To Remove Putty From Your Window
Step 1: Use the Right Tools
Before removing old putty, it is important to have the correct tools and protective gear:
Putty knife or chisel
Heat gun or hairdryer
Safety goggles and gloves
Drop cloth or protective covering
Glass cleaner or vinegar solution
Safety is especially important when working around older glass, cracked panes or timber frames that may already be weakened.
Step 2: Soften the Old Putty
Use a heat gun or hairdryer to gently heat the putty around the windowpane. Move the heat source slowly along the line of putty to soften it without damaging the glass or wooden frame. Avoid holding heat in one spot too long, overheating can crack the glass.
Step 3: Remove the Old Putty Completely
Once softened, the old putty should be removed in sections using a putty knife or chisel. The goal is to remove all loose, cracked and brittle material without damaging the glass or frame. For a long-lasting result, all old putty needs to be cleared away before the window is cleaned and prepared.
Step 4: Clean and Prepare the Window Frame
DIY reglazing may be suitable for very small, low-risk jobs, but it is not always the safest or most practical option.
You should consider calling a professional glazier if:
- The glass is cracked or broken
- The window is large or difficult to access
- The frame is damaged or rotten
- The glass is in a door or high-traffic area
- You are unsure what type of glass is required
- The repair is urgent
A professional glass repair service can assess the window, recommend the correct glass, remove damaged materials and complete the repair properly.

Frequently Asked Questions
Is reglazing cheaper than replacing the whole window?
In many cases, reglazing can be more cost-effective than replacing the entire window, especially if the frame is still in good condition. A glazier can advise whether repair or replacement is the better option.
Can old window putty be repaired?
In some cases, small areas of damaged putty can be repaired. However, if the putty is brittle, cracked or separating from the frame, it is usually better to remove it properly and reglaze the window.
