Before You Choose

What We Look at Before Recommending New Windows

A useful window estimate should explain more than the total price. We examine the visible condition of the existing windows, discuss the problems you have noticed and review what the installation will require. This helps determine which products, glass options and installation method make sense for your home.

Existing window condition

We check the visible frame, operation, seals and surrounding finishes for problems that could affect the installation.

Problems you want solved

Drafts, difficult operation, failed glass and room comfort concerns can point to different solutions.

Style and glass choices

Ventilation, cleaning, exposure, natural light and budget help guide the window and glass configuration.

Required finishing work

We review interior trim, exterior capping and other finishing details that should be included in the quote.

We explain whether retrofit or full-frame installation appears appropriate based on the visible condition of the opening. Conditions concealed behind the existing frame may only become visible after removal.

Homeowners in Fonthill and throughout Pelham receive clear recommendations and written pricing before deciding how to proceed.

Repair or Replace?

Signs Your Windows May Need More Than a Simple Repair

A broken crank, damaged screen or worn piece of weatherstripping does not automatically mean the entire window needs replacing. Replacement becomes worth investigating when the window has several problems, the frame is deteriorating, or the opening can no longer be sealed properly.

Persistent drafts around the opening

Air leakage may come from worn weatherstripping, poor sash alignment, gaps around the frame or an inadequately insulated opening. The source should be identified before replacement is recommended.

Fog or moisture between the panes

Moisture trapped between panes usually indicates that the sealed glass unit has failed. Depending on the window’s age and condition, replacing the glass may sometimes be an alternative to replacing the complete window.

Soft, cracked or deteriorated frames

Visible deterioration can affect how securely the window fits and seals. Any moisture source should also be investigated so the same problem does not affect the new installation.

Windows that no longer open or lock properly

Difficult operation can result from failed hardware, sash distortion or movement in the existing frame. An assessment helps determine whether a repair is practical.

Water staining around the window

Staining, peeling paint or damaged drywall may point to a problem with the window, exterior finishing, flashing or another source above the opening. Installing a new window without identifying the source may not solve the leak.

Noticeable discomfort near closed windows

Cold glass, air leakage and older window construction can make nearby rooms less comfortable. The window condition and installation around the opening should both be considered.

Condensation does not always mean the window has failed

Moisture on the room-facing surface of the glass can be affected by indoor humidity, outdoor temperature, window coverings and airflow. Condensation between sealed panes is a different issue and commonly indicates seal failure.

If you are experiencing these problems in a Fonthill or Pelham home, we can inspect the existing windows and explain whether repair, retrofit installation or full-frame replacement is the most sensible next step.

Installation Options

Retrofit vs. Full-Frame Window Replacement: What’s the Difference?

Retrofit and full-frame replacement are two different ways of installing a new window. Neither method is automatically better for every home. The appropriate choice depends on the condition of the existing frame, the finishing work required and what you want the project to accomplish.

Keeps the Existing Frame

Retrofit (Insert) Installation

With a retrofit installation, the existing window frame remains in place and the new window is fitted inside it after the old operating components are removed.

  • Best considered when: the existing frame is dry, square, secure and in suitable condition.
  • Interior impact: most existing trim can usually remain in place, reducing disruption inside the home.
  • Exterior finishing: custom aluminum capping can protect and finish the existing exterior frame.
  • Important trade-off: because the new frame fits inside the old one, the visible glass area may be slightly reduced.
  • Not intended to solve: deterioration or moisture problems within an existing frame that should be removed.
Replaces the Complete System

Full-Frame Installation

Full-frame replacement removes the existing window, frame and related components back to the rough opening before the new window system is installed.

  • Best considered when: the old frame is damaged, poorly fitted, deteriorated or no longer suitable for an insert.
  • Access to the opening: removing the old frame allows the exposed opening to be checked before the new unit is insulated and installed.
  • Interior finishing: new jamb extensions, casing or other trim work may be required.
  • Exterior finishing: brickmould, custom aluminum capping or another finish may be used depending on the home.
  • Important trade-off: full-frame installation involves more labour and finishing work, which normally makes it more expensive than retrofit installation.
Make sure competing quotes specify the installation method

Two quotes can include similar-looking windows but very different installation work. Confirm whether each quote is for retrofit or full-frame replacement and whether interior trim, insulation, exterior finishing, removal and cleanup are included.

For homes in Fonthill and throughout Pelham, we base the recommendation on the visible condition of each opening and explain the work included in the quote. Conditions concealed behind an existing frame cannot always be confirmed until that frame is removed.

Glass and Efficiency

How to Choose the Right Glass Package for Each Room

Glass options should be selected according to the room, window size, sun exposure and comfort concerns—not simply by choosing the most expensive package for every opening. Rooms on opposite sides of the same house can have different glass requirements.

Low-E coatings and solar control

Low-emissivity coatings help control heat transfer through the glass. Different coatings can also affect solar heat gain and visible light, making window orientation important.

Double-pane versus triple-pane

Triple-pane glass can improve thermal performance and raise the interior glass temperature during cold weather, but it also adds cost and weight. It is not automatically necessary for every room.

Gas fill and sealed airspaces

Argon gas between panes helps slow heat transfer through an insulated glass unit. Its purpose is thermal performance; it does not correct air leakage around the sash or frame.

Warm-edge spacer systems

The spacer separates the panes around the perimeter of the sealed unit. A warm-edge system helps reduce heat transfer near the glass edge and can lower the potential for condensation.

Included in Every Window We Install LoĒ-i89 Comes Standard—It Is Not an Upgrade

Every replacement window installed by Great Northern Home Exteriors includes LoĒ-i89 glass. The room-facing Low-E coating reflects radiant heat toward the interior and helps lower the window’s U-factor. In certain double-pane configurations, I-89 can approach the thermal performance of some triple-pane units without adding a third pane of glass. You do not have to pay extra or request it as an upgrade.

How I-89 Works →
Fonthill and Pelham Considerations Exposure Matters, but Glass Is Only One Part of the Window

Some homes in Fonthill and other parts of Pelham have windows facing open, elevated or less-sheltered exposures. Wind can make existing air leakage more noticeable, while strong afternoon sun can create different comfort concerns on another side of the same house.

We consider the window’s orientation, size, operating style, compression seals, frame condition and installation method alongside the glass package. Selecting better glass will not correct gaps or poor sealing around an existing frame.

Feeling cold near a window does not always mean there is a draft A draft involves moving air. You can also feel colder beside a large pane of cold glass even when the window is properly sealed.

We explain the available options so you can compare thermal performance, solar control and price without automatically choosing the same glass package for every window.

Choosing a Style

Choose a Window Style Based on the Room—not Just the Look

Window style affects ventilation, cleaning, exterior clearance, glass area and price. The best choice depends on how the room is used and whether the opening needs ventilation, an unobstructed view or a window that does not project outside when opened.

Casement-style window installed on a home exterior
Wide Ventilation

Casement Windows

Hinged at the side and opened with a crank, casement windows provide a large ventilation opening and use compression seals when locked.

Useful for: kitchens, living areas and rooms where generous airflow is wanted.

Consider: the sash projects outside and needs clearance from walkways, decks and landscaping.

Light and Views

Picture Windows

Picture windows are fixed and do not open. Their simple construction provides a large glass area without moving sashes or hardware.

Useful for: natural light, larger views and openings where ventilation is not required.

Consider: pair them with casement or awning windows when the room also needs fresh air.

Horizontal sliding window installed on a home
No Outward Swing

Sliding Windows

Sliding windows open horizontally along their tracks and do not extend beyond the exterior wall.

Useful for: openings near patios, decks, walkways and other areas with limited exterior clearance.

Consider: tracks and drainage channels should be kept clean so the sash continues operating properly.

Double-hung window installed on a home
Top and Bottom Airflow

Double-Hung Windows

Both sashes operate vertically, allowing ventilation through the top, bottom or both sections of the window.

Useful for: traditional designs and rooms where flexible ventilation is helpful.

Consider: tilt-in sash operation can make exterior glass easier to clean from inside.

Bay window installed on a homeBow window installed on a home
Projecting Window

Bay and Bow Windows

Bay and bow windows extend beyond the exterior wall, creating a deeper sill and a wider view from inside the room.

Useful for: creating a focal point, increasing glass area and adding display or seating space when designed for it.

Consider: support, roof, base insulation and exterior finishing make these more involved than a flat window.

Awning window installed by Great Northern Home Exteriors
Compact Ventilation

Awning Windows

Hinged at the top, awning windows open outward from the bottom and can provide ventilation during light rain.

Useful for: bathrooms, kitchens, higher placements and combinations with larger fixed windows.

Consider: the sash projects outside, so exterior clearance and placement still matter.

One home can benefit from several window styles

You do not need to select one operating style for the entire house. A picture window may suit a living room view, casements may provide ventilation elsewhere, and sliders may work better where exterior clearance is limited.

For homes in Fonthill and throughout Pelham, we recommend each style according to the opening, room use, ventilation needs and exterior clearance—not simply because one style is currently popular.

Pricing Factors

What Affects Window Replacement Cost in Pelham?

There is no accurate flat price for every replacement window. Two openings that appear similar can require different window configurations, glass, installation methods or finishing work. We measure the openings and review the project before providing a written price.

Window size and configuration

A small fixed window, a combination unit and a projecting bay or bow require different amounts of glass, framing, hardware and labour.

Operating style and hardware

Fixed windows have no operating hardware. Casements, sliders, awnings and double-hung windows use different sash and hardware systems.

Pane and glass selections

Double versus triple pane, solar-control coatings, privacy glass, decorative glass and required safety glass can affect the price.

Retrofit or full-frame installation

Full-frame replacement normally involves more removal, insulation and finishing work than installing a new unit within a suitable existing frame.

Interior and exterior finishing

New casing, jamb extensions, brickmould, custom aluminum capping, colour choices and transitions to brick or siding all affect the scope.

Access and changes to the opening

Upper-storey access, difficult working areas, enlarged openings and structural alterations can require additional labour, materials or permits.

LoĒ-i89 is included in every window GNHE installs. It is not treated as an optional glass upgrade or added only after the estimate.

What Should Be Identified in a Window Quote?

A written quote should make it possible to understand what you are purchasing and compare the scope—not just the total at the bottom.

Window styles and configurations

Double- or triple-pane glass

Retrofit or full-frame installation

Interior finishing and trim

Exterior capping or brickmould

Applicable taxes and payment terms

Product and workmanship warranties

Homeowners in Fonthill and throughout Pelham receive clear written pricing before deciding whether to proceed. We explain what is included without using an artificially low per-window number that leaves necessary installation work out of the conversation.

Planning Your Project

A window replacement plan that works with your Pelham home

Pelham has a real mix of homes—from established streets in Fonthill and Fenwick to newer neighbourhoods, country properties and custom builds. A good window plan should account for that. We look at how the new windows will function, how they will be finished and how they will fit with the rest of your home.

Keep the new windows consistent with your home

Many established homes have been updated more than once. We compare the existing window proportions, exterior colours, grille patterns and trim so the replacements look intentional instead of like they arrived from three different decades.

Replace the windows that need attention first

You may not need to replace every window at once. Failed glass seals, damaged frames, difficult operation and uncomfortable rooms can be addressed first while keeping the overall appearance consistent for future phases.

Account for access and unusual openings

Rural and custom properties may include larger windows, additions, upper-level openings or landscaping that affects access. We review those details before quoting so the installation plan reflects the actual job—not just the number of windows.

Planning to replace your windows in stages?

Choose the overall look before the first phase begins. Keeping a record of the window style, exterior colour, grille pattern, hardware and finishing details makes it much easier to match the remaining windows later.

Whether you are replacing one problem window or planning a complete window replacement in Pelham, we inspect the openings, discuss what you want to improve and provide a clear written estimate. We install windows throughout Pelham, including:

Ontario Rebate Information

Window rebates available through Ontario’s Home Renovation Savings Program

Eligible Pelham homeowners may receive a rebate when qualifying windows or doors are installed as part of the assessment-required stream of the Home Renovation Savings Program. The assessment and program registration must be completed before renovation work begins.

$100 per eligible rough opening
The rebate is based on rough openings—not the number of window units

A wide opening containing several window sections normally counts as one rough opening. At least three window rough openings, or one qualifying exterior door, skylight or sliding door rough opening, must be upgraded for this category to qualify.

Begin with an energy assessment

An initial assessment must be completed by a registered energy advisor before any eligible work begins. A follow-up assessment is also required after the upgrades are finished.

Complete at least two upgrade categories

Windows and doors count together as one upgrade category. Homeowners must complete at least one other eligible upgrade, such as qualifying insulation, air sealing or a heat-pump water heater.

Install complete ENERGY STAR® models

Eligible work must replace a non-ENERGY STAR model with a complete ENERGY STAR-certified window or door and frame. Glass-only, sash-only and door-slab-only replacements do not qualify.

$600 assessment rebate

A $600 rebate is available to help offset the cost of the initial and follow-up assessments after the homeowner successfully completes the program.

How the rebate process works
1 Check eligibility

Review the official program requirements before starting.

2 Book the first assessment

Complete the initial assessment before renovation work begins.

3 Complete the upgrades

Use qualified products and keep the ENERGY STAR labels attached.

4 Complete the follow-up

Your advisor submits the required documents after the final assessment.

Check before ordering or installing anything

Program eligibility depends on the homeowner, property, heating source, selected upgrades and completion of every required step. Keep all ENERGY STAR labels attached until after the follow-up assessment. Great Northern Home Exteriors can provide product and installation documentation, but final rebate approval is determined by the program administrator.

Check Current Eligibility

Rebate amounts and requirements can change. Always confirm the current terms directly with the Home Renovation Savings Program before beginning your project.

Homeowner Questions

Pelham Window Replacement FAQ

Straightforward answers to common questions about planning and completing a window replacement project in Pelham.

How much does window replacement cost in Pelham?

Pricing depends on the size and number of windows, operating style, glass configuration, installation method, exterior finishing and access around the openings. A standard retrofit window will generally require less labour than a full-frame replacement or a larger bay or bow installation. We inspect and measure the openings before providing a clear written estimate so you can see what is included.

Do I need a building permit to replace my windows?

Permit requirements depend on the scope of the project. A straightforward replacement within the existing opening is different from enlarging an opening, altering structural framing or changing a window required for bedroom egress. If structural work is planned or there is any uncertainty, confirm the requirements with the Town of Pelham Building Department before work begins.

What’s the benefit of choosing full-frame installation?

Full-frame installation removes the existing window, frame and surrounding components so the rough opening can be exposed. This allows the installer to examine the opening, install new insulation and create new interior and exterior finishes around the window. It may be appropriate when frames are deteriorated, previous installation work is questionable or you want to change the finished appearance. The age of a home alone does not automatically mean full-frame installation is necessary.

How long does a window installation take?

Smaller window replacement projects can often be completed in one working day. Whole-home projects, full-frame installations, bay or bow windows and openings needing additional repairs can take longer. Weather, access and unexpected conditions behind the old frames may also affect the schedule. We review the expected installation time with you before work begins.

Where can I find local renovation or energy-efficiency resources?

The Town of Pelham provides current building and permit information for local renovation projects. For provincial energy-efficiency incentives, homeowners should review the official Home Renovation Savings Program before beginning work because eligibility requirements and rebate amounts can change.
