Foggy Window Repair in Vaughan & the GTA

Find out whether the moisture is on the glass or trapped inside it.

Cloudiness that sits between panes can point to a failed insulated glass unit. Strataline assesses the seal, sash and frame, then explains whether a replacement sealed unit can restore a clear view while retaining the window.

Surface condensation and a failed seal are different problems

Room-side condensation forms on the accessible surface of the glass when moisture in the air meets a cold surface. Exterior condensation can also appear under suitable weather conditions. Neither, on its own, proves that the sealed unit has failed.

Moisture, haze or streaking between panes cannot be wiped away from the room. That calls for assessment of the insulated glass unit and its edge seal. Describe when the fogging appears and where you can see it.

A sealed unit is the glass assembly, not the whole window

An insulated glass unit contains panes separated by a spacer and sealed around the edge. It sits within the window sash or frame. Replacing a failed unit can be an option when the surrounding system remains serviceable.

Cleaning or a surface treatment does not repair a failed internal seal. We assess replacement of the sealed unit rather than promising that a defogging treatment will return its original insulating performance. Glass replacement also does not resolve unrelated leaks or worn weatherstripping.

The right fit

What we check before recommending replacement

A sound installation depends on the existing window or door as well as the new glass.

  • The fogging is between panes, rather than surface moisture alone.
  • The sash, frame and glazing seals are in serviceable condition.
  • The replacement unit fits the system’s thickness and weight limits.
  • Sources of water entry or poor drainage are considered separately.

From first photos to final fit

Four steps to replacement

  1. 01

    Send photos or call

    Tell us what has happened, how many panes are affected and where the property is. Photos help us prepare for the assessment.

  2. 02

    Assess and measure

    We check the glass, sash, frame and access, then take the measurements needed for a suitable replacement.

  3. 03

    Confirm the order

    Review the specification, price, expected production time and installation scope before the glass is ordered.

  4. 04

    Install and clean up

    Protect the surrounding finishes, replace the glass and complete the agreed sealing, disposal and cleanup.

What affects the price?

The quote depends on the glass and the work needed to fit it properly. Photos help us start the conversation; final measurements and the specification determine the order.

Allow for measuring and fabrication

The replacement is measured and specified before fabrication. Non-standard shapes, coatings, internal grids and production schedules can affect availability. We discuss expected ordering and installation timing with your quote.

FAQ

Questions about foggy windows & sealed units

What does fogging between the panes usually mean?

Persistent moisture inside a sealed glass assembly calls for assessment of the unit and its edge seal. It cannot be wiped off by cleaning the exposed surfaces. A suitable sash and frame may allow the sealed unit to be replaced without changing the entire window. Frame condition, glazing details and the availability of compatible parts determine whether that repair is practical.

Why can condensation appear on a window that is not leaking?

Moisture on an accessible room-side or outside glass surface can result from the relationship between temperature and humidity. That differs from moisture trapped between sealed panes. Identify which surface is affected and when it appears before deciding on a repair. Replacing glass does not automatically resolve the room conditions that produce surface condensation.

Can damaged glass be replaced without replacing the whole window?

Often, when the frame and sash are sound and the system can be reglazed. For an insulated unit, the panes and edge seal form an assembly, so damage to one pane generally calls for assessment of the complete sealed unit. Rot, distortion or unavailable compatible parts can change the recommendation. The surrounding frame is checked before deciding on a glass-only repair.

Glass replacement options

Why does replacement glass need its own final measurement?

The visible glass area is not necessarily the ordering size. The unit’s thickness, construction, edge arrangement and fit within the sash or panel also need checking. Photographs support an initial review, but fabrication needs confirmed dimensions and specifications. Ordering by the exposed pane alone can produce glass that does not suit the existing glazing system.

Should I choose double-pane or triple-pane glass?

Compare the actual available glass options for the room, exposure, window size, operating style, comfort needs and budget. The number of panes alone does not describe the complete window’s performance. We review the selected system and current specifications before ordering. No particular energy saving or noise reduction should be assumed without the relevant product information.

Will replacing windows solve every draft in the room?

No. Drafts can come from the operating seals, frame joints, the installation perimeter or other parts of the room. The assessment should identify where air is entering before choosing the scope. A glass-only repair does not address failed weatherstripping or a wall-to-frame gap. Replacement needs to be coordinated with the actual cause of discomfort.

What if water is entering around the window frame?

The source needs investigation before choosing a glass repair or replacement. Water can travel through surrounding wall details, frame joints or drainage paths and appear at a different point inside. We document deterioration revealed during removal and discuss the required correction. A new unit and fresh caulking should not conceal an unresolved wall or flashing problem.

What does Strataline’s lifetime workmanship warranty cover?

We warrant our labour and installation to the original client for as long as that client owns the property, subject to the applicable manufacturer-warranty period for supplied products. Where no meaningful manufacturer warranty exists, workmanship coverage continues through the original client’s ownership. If a problem is caused by our workmanship, we return and correct it. Coverage ends when the property is sold or another contractor modifies or repairs the covered work.

The warranty covers genuine labour or installation defects. It excludes ordinary dirt, normal wear, accidental damage, misuse, inadequate maintenance, unrelated water intrusion, structural movement and client-supplied product defects.

Can replacement glass match the nearby panes?

We review visible tint, spacer appearance, internal grids, privacy texture and other details relevant to the opening. The original product or pattern may no longer be available, so an exact match cannot be assumed. Confirm the proposed appearance before ordering, particularly where adjacent units will be seen together. The glass specification still needs to suit the retained system.

What affects the wait for replacement glass?

Dimensions, shape, glass construction, decorative details, supplier production and access for installation affect timing. Measurement, fabrication and installation are separate stages. The expected sequence is discussed with the quote once the required unit is understood. A standard-looking opening can still need a custom sealed assembly, so an immediate replacement should not be assumed from a photograph.

Who handles a warranty claim for a product Strataline supplied?

For a potential manufacturing defect within the applicable warranty period, we inspect the issue, document the condition, gather photographs and evidence, communicate with the supplier or manufacturer, and coordinate the claim for you. Strataline covers removal and reinstallation labour associated with a valid supplied-product warranty issue.

The replacement product is governed by the manufacturer’s written warranty; approval is not guaranteed. If a claim is denied because we installed the product incorrectly, we correct our work.

Can you install products I buy myself, and who covers them?

We may install client-purchased doors, windows, flooring, tile, plumbing fixtures, lighting, hardware and similar products. We remain responsible for the workmanship of our own installation. You remain responsible for the product warranty, defects, missing components and compatibility.

Replacement products and additional removal or reinstallation caused by a client-supplied product failure are chargeable. Such products can also affect price and schedule, so send the complete product information before buying or booking installation.

How long is a quote valid, and are website prices before tax?

Written quotes are normally valid for 30 days unless the quote states otherwise. Public website price ranges are before HST. Supplier pricing and availability can change after a quote expires, so an older estimate should be reconfirmed before products are ordered or a date is booked. The current written agreement sets the amount and terms for your project.
