Glass repairs before you sell in Hobart: what pays and what does not
Fix the broken and the obviously failed. Do not buy the upgrades. Replacing a cracked pane at $180 to $450, and bringing non-compliant glass in a door or a bathroom up to Grade A at $350 to $750, are both worth doing, because both land in a pre-purchase building report and a buyer discounts a written defect by far more than it costs to fix. Retrofitting double glazing across the house at $9,000 to $22,000 will not come back in the price. The rule we give sellers: fix defects, skip improvements, and have everything finished three weeks before the photographer arrives.
Fourteen glass jobs, what each costs, and a straight verdict
These are the jobs sellers and agents ask us about in Hobart. Costs are 2026 supplied-and-fitted figures. The middle column is deliberately honest about the difference between adding value and protecting value, because most glass work does the second, not the first.
| The job | 2026 cost | What it realistically adds or protects | Verdict |
|---|---|---|---|
| Replace a cracked or broken pane | $180 to $450 per pane | Removes the single most visible defect in a house. Buyers price a broken window at several times the repair, and it flags neglect everywhere else. | DO IT |
| Upgrade plain glass in a door, side panel or bathroom to Grade A safety glass | $350 to $750 per pane | Removes a safety item from the building report. This is the item buyers negotiate hardest on, because it reads as a hazard rather than a repair. | DO IT |
| Reglaze and reputty failing timber sashes | $220 to $480 per pane | Stops a timber rot write-up around the glazing and protects the sash itself from a $600 to $1,400 splice later. | DO IT |
| Repair window locks, stays and catches | $150 to $400 | Inspectors test windows and write up any that will not open, close or lock. Cheap to fix, disproportionately damaging in a report. | DO IT |
| Professionally restore etched or scummed shower glass | $180 to $350 | Makes a sound bathroom photograph properly. Cloudy shower glass is the fastest way to make a clean bathroom look tired. | DO IT |
| Replace one to three fogged double glazed units | $450 to $900 each | Fogged glass photographs badly and makes buyers assume every unit in the house has failed. Fixing a few kills that assumption. | DO IT |
| Replace fogged units right across a house | $3,600 to $7,200 for eight | Real money against a marginal gain unless the property is at the top of its street. Often better disclosed with a quote attached. | ONLY IF premium home |
| New glass splashback in a kitchen | $600 to $1,300 | Lifts a sound kitchen noticeably. In a tired kitchen it does the opposite, because one crisp new surface shows up the benchtop and the doors. | ONLY IF cabinets and benchtop are sound |
| Replace a dated but working framed shower screen | $700 to $1,400 | Moderate. It matters in a bathroom that is otherwise presentable and it is invisible in one that needs redoing. | ONLY IF the bathroom is otherwise fine |
| Replace mirrors | $300 to $700 each | Nobody notices a sound mirror. Everybody notices black spotting creeping in from the edges in a bathroom. | ONLY IF visibly deteriorated |
| Upgrade a framed screen to frameless | $1,200 to $2,800 | A real improvement to live with and close to nothing at auction in a mid market Hobart bathroom. | SKIP IT |
| Full house double glazing retrofit | $9,000 to $22,000 | A genuine comfort and condensation fix that you will not recover in the sale price. Worth doing for yourself, not for a buyer. | SKIP IT |
| Secondary glazing or magnetic acrylic panels | $250 to $600 per window | Reads to buyers and inspectors as a temporary fix over a cold house, and invites the exact question you were trying to avoid. | SKIP IT |
| Bold coloured or printed feature glass | $600 to $1,300 | Narrows your buyer pool for no gain. Neutral glass offends nobody and photographs better under agent lighting. | SKIP IT |

What buyers actually notice, and what they do not
Buyers walking through a Hobart open home in July are not measuring U-values. They are looking at whether the house feels dry, light and looked after, and glass carries a disproportionate share of that impression because it is at eye level in every room.
What they notice: water sitting on the inside of the panes and staining on the sill beneath, black mould in the corner of a window reveal, a pane that has fogged so the view has gone milky, a crack running across an otherwise tidy room, a shower screen you cannot see through, and mirrors with black spotting creeping in from the edges. What they do not notice: glass thickness, whether a screen is framed or semi-frameless, the brand of the hardware, or the fact that a splashback is 6mm rather than 5mm toughened.
The pattern is clear enough. Buyers respond to signs of moisture and neglect, not to specification. That is why $180 spent restoring shower glass usually outperforms $1,600 spent on a smarter shower screen, and why clearing the condensation staining off a sill and repainting it beats almost anything you could buy. If Hobart winter condensation is the real problem in your house, read the signs of failed double glazing and single versus double glazing to work out whether it is a glass fault or a ventilation habit before you spend anything.
What a pre-purchase building report writes up, and what that costs you
Most Hobart buyers commission a standard pre-purchase property inspection, and glass appears in these reports far more often than sellers expect. Five findings recur.
- Cracked, broken or missing glass. Written up as a defect every single time, whatever the size of the crack. A $180 to $450 fix that becomes a bargaining chip worth several times that.
- Plain glass where safety glass is required. Doors, panels beside doors, bathrooms and low level glazing near floor height are the usual spots, and older Battery Point, North Hobart and New Town homes are full of them. It is reported as a safety hazard, which reads far worse than a maintenance item. Fixing it is $350 to $750 a pane and the detail is on our AS 1288 compliance page.
- Rot or decay in timber around the glazing. Perished putty lets water sit in the rebate, and the rebate is where a sash starts to go. Reglazing and reputtying at $220 to $480 a pane now is cheaper than a $600 to $1,400 sash splice later, and far cheaper than the $1,500 to $3,500 a made to match heritage sash costs.
- Windows that will not operate or lock. Inspectors physically test a sample. A stuck sash, a broken stay or a lock that will not engage is a written line, and it costs $150 to $400 to fix.
- Moisture, mould and staining at window reveals. This is the Hobart special. The report usually notes it as a possible moisture issue, which is the phrase that makes buyers nervous and brings in a second opinion.
Add those together on a typical older Hobart house and you are usually looking at $600 to $2,000 to clear the whole glass section of a report. Against a negotiation on a three-quarters of a million dollar property, that is the cheapest insurance on the list.
Walking through before the campaign?
Send photos of every window you are unsure about. We will tell you which ones are worth fixing, which ones are not, and price only the ones that are.
Fix it or disclose it: how to decide
There is a clean line here and it sits at roughly $800. Below that, and where the defect is visible or testable, fix it. The discount a buyer applies to a written defect is almost always larger than the repair, because they are pricing uncertainty rather than glass. Above that, and where the work is structural or would leave the house looking half finished during a campaign, get a written quote, disclose it, and let the buyer price a known number instead of imagining a worse one.
Three rules we would give any seller. First, never patch to conceal: taping a crack, puttying over rot or siliconing a failed unit is the thing that turns a small negotiation into a trust problem, and inspectors find it. Second, if you fix something, finish it, including the paint and the beads, because a fresh pane in an unpainted rebate looks worse than the crack did. Third, keep the invoices. An itemised invoice saying the door glass was upgraded to Grade A toughened is worth more at the negotiating table than the work itself, because it answers the question before it is asked.
Timing: work backwards from the photographer
Glass has a lead time and campaigns do not wait. Standard clear float in a common size is often next business day because it is cut from stock. Everything else is made to order: toughened, laminated, double glazed units, shower screens and printed splashbacks typically take 3 to 10 business days from the measure, and busy periods stretch that. Fresh linseed putty on a reglazed timber sash needs time to skin before it takes paint, which adds another week or two on a heritage job.
Work back from the photo shoot, not from the first open home. Three weeks is comfortable for most jobs and four is right if heritage sashes or a full set of units are involved. Booking the measure early costs nothing and locks in your place in the supplier run. If you are doing double glazing anyway, our note on the best time of year for double glazing in Hobart explains why the winter queue is the longest one.
The honest bit: three things we would tell you not to buy
We make more money if you do all of these. We are telling you not to, because a seller who trusts the advice is the one who calls back for the next house.
Do not double glaze the house to sell it. At $700 to $1,600 a window a typical Hobart home is $9,000 to $22,000, and the Tasmanian market does not currently pay that back at settlement. If you have a cold house and you are leaving it, disclose the single glazing, get a quote so buyers can see the real number, and put your money into the two or three panes that are actually broken. Double glazing is a comfort purchase and a long-hold purchase, and our double glazing page says the same thing when nobody is selling.
Do not replace a shower screen that only needs a clean and a seal. A professional restoration of etched glass is $180 to $350 and a new bottom seal and a set of hinges is $80 to $350. That is often the whole job. Compare it against $700 to $1,400 for a new framed screen before you commit, and see shower screen maintenance for what is actually recoverable.
Do not replace mirrors that are fine. A mirror only reads as dated when the silvering has gone black at the edges or the frame is broken. Otherwise buyers do not see it. Spend the $300 to $700 on the entry door glass instead, where every single person who comes through will touch it. Our mirror page covers when replacement is genuinely the answer.
