Broken Window Glass Replacement
Cost, Glass Types & First Steps (2026)

First: make it safe

1. Clear the area. Keep children and pets out of the room and off the floor below the window, inside and outside.
2. Protect your hands and feet. Thick gloves, closed shoes and long sleeves. Ordinary float glass breaks into long, sharp shards.
3. If the pane is cracked but still in place, run strong tape across both faces in a cross pattern so it cannot fall out in a gust.
4. If pieces are loose, lift them out one at a time, starting from the top, so pieces above cannot drop onto your hands, and wrap them in newspaper or cardboard before binning.
5. Cover the opening with plywood, a corrugated plastic sheet or thick plastic taped to the frame, to keep out rain and insects.
6. Record the damage before clearing up if you plan to claim on household insurance or from whoever broke it.

Why the glass broke

Knowing the cause decides whether a like-for-like pane is enough or whether something else needs fixing at the same time.

Tempered panels that burst on their own, such as shower screens and glass doors, are a separate subject covered in our tempered glass breakage guide.

Replace the glass, or the whole window?

Most broken panes only need new glass. The frame, beads and gaskets stay, the broken glass is removed, the rebate is cleaned, and a new pane is set in with new glazing gaskets or sealant. The whole window only needs replacing when the frame itself has failed: corroded aluminium, a twisted sash, rotten timber, or a design you wanted to change anyway.

• Sliding and casement windows: usually glass only, if the sash runs and closes properly.
• Louvre (nako) windows: a single broken blade can be replaced, but many owners take the chance to change the whole nako; see our nako window replacement guide.
• Sealed double-glazed units: the whole sealed unit is replaced, not one pane of it.
• Old timber windows: check the frame for rot before ordering glass to fit it.

If the frame also leaks, sticks or rattles, our window replacement guide explains when a full frame swap is better value.

Choosing the replacement glass

Any pane a person can walk into, fall against or reach through, low-level glazing, a full-height panel, anything beside a stair or in a bathroom, is a case for safety glass rather than repeating the ordinary float that broke. That is a safety decision first and a cost decision second.

Thickness, size and lead time

Match the thickness the frame was designed for, because the glazing bead and gasket only grip a certain thickness. Residential sliding windows commonly use 5 mm float; doors and large panels need thicker tempered glass. The glazier reads the existing glass and the frame before ordering.

• Ordinary float can be cut to size from stock, so it is usually the quickest to replace.
• Tempered glass cannot be cut after it is toughened. It is cut, drilled and notched first, then toughened, so it has to be measured exactly and ordered, which takes longer.
• Laminated and frosted panes may also be ordered in.
• Board up the opening properly while you wait for tempered or laminated glass; it is safer than leaving a cracked pane in.

How the replacement is done

1. Measure the opening and note the glass type and thickness.
2. Remove the beads or gaskets and lift out the remaining broken glass.
3. Clean the rebate of old sealant, glass chips and dirt.
4. Fit new glazing gaskets or setting blocks so the glass does not touch the metal.
5. Set the new pane, refit the beads and seal where the window design needs it.
6. Check the sash opens, closes and locks, and that rain will drain out, not in.

Ask for the old gaskets to be replaced, not reused; worn gaskets are a common cause of the rattles and leaks covered in our window leak repair guide.

Condos, landlords and insurance

• Condo facade windows: replacement glass usually has to match the building's tint and type. Check with management before ordering, and book access for any work from outside.
• Renting: who pays depends on the tenancy agreement and how it broke; tell the landlord in writing before arranging a repair.
• Household insurance: some policies cover accidental glass breakage. Check the policy wording and the claim steps before work starts.

What it costs

These are ClickBina's published figures (indicative 2026, Klang Valley). Glass prices are supply only, per sq ft; cutting, fabrication, delivery and fitting are added.

When a glass-only quote comes close to the per-panel replacement figure, ask for both prices side by side. If the frame is tired, a new panel may be the better buy.

What to send so it can be priced

• Your area and the property type, and which floor the window is on.
• The window type: sliding, casement, nako, fixed panel or door.
• The size of the broken pane, width and height, as close as you can measure.
• What the glass looks like: clear, tinted or frosted, and whether you know it was tempered.
• Whether the frame is damaged or the window was already sticking or leaking.
