What Homeowners Say About GNHE
Real feedback from homeowners who chose Great Northern Home Exteriors for window replacement and installation.
Retrofit or Full-Frame Window Installation?
The condition of your existing frames helps determine which approach is suitable. GNHE assesses them before recommending an installation method.
Retrofit Window Replacement
Retrofit replacement fits a new window into a sound existing frame. It can preserve interior trim and reduce disruption, but the retained frame reduces the space available for the new window.
- Suitable when the existing frame is sound and square
- Existing interior trim may remain
- New window fits within the retained frame
- Capping and sealing included as specified in the estimate
Full-Frame Window Replacement
Full-frame replacement removes the window and its frame, exposing the opening for inspection. It allows damaged material to be addressed and usually requires new interior trim and exterior finishing.
- Suitable for deteriorated or unsuitable existing frames
- Exposes the sill and surrounding opening
- Allows insulation and water-management details to be addressed
- New jambs, trim and exterior finishes specified in the estimate
Your written estimate identifies the installation method and finishing work, so you can compare quotes on the same scope.
What Affects Window Replacement Cost in Welland?
The price depends on the windows you choose and the work needed to install them. GNHE reviews your measurements, existing frames and finishing requirements before preparing a free written estimate.
Number of Windows
Replacing one window, several rooms or every window in your home changes the quantity of materials and installation work. Your estimate lists the windows included in the project.
Size & Configuration
Window dimensions and style affect product cost. Large picture windows, bay and bow units, and combinations of fixed and opening windows have different manufacturing and installation requirements.
Glass & Frame Options
Glass specifications, frame colours and selected features can change the price. Compare quotes using the same product specifications so the differences are clear.
Installation Method
Retrofit installation retains a suitable existing frame. Full-frame replacement removes it and generally involves more removal, preparation and finishing work.
Existing Frame Condition
Deteriorated wood or damage around the opening can require additional repairs. Ask how unforeseen damage discovered during removal will be documented and priced.
Interior & Exterior Finishing
New jamb extensions, interior casing and exterior aluminum capping can affect the total. Your estimate identifies the finishing work included around each replacement.
Compare the complete scope of work as well as the price. Your GNHE estimate identifies the selected windows, installation method and included finishing, so you know what you are paying for.

Energy-Efficient Replacement Windows
If rooms feel cold near the windows in winter or overheat in summer, glass performance is worth considering alongside window style. GNHE helps Welland homeowners compare the specifications of their selected replacement windows before ordering.
i89 Glass Included
GNHE window packages include i89 glass. Your written estimate identifies the selected glass package. When comparing options, ask for the whole-window performance ratings for your chosen model and size, rather than relying on the glass name alone.
Window Styles & Configurations
Choose each window around how you use the room. Consider ventilation, the view and whether an opening sash would interfere with a walkway, deck or other exterior space.
Casement
Hinged at the side and opened outward with a crank. A practical choice for ventilation, with no horizontal meeting rail across the centre of the glass.
Awning
Hinged at the top and opened outward from the bottom. Often used in shorter openings or paired with fixed glass to add ventilation.
Sliding
Sashes slide horizontally within the frame. Useful for wider openings and areas where an outward-opening window would obstruct exterior space.
Hung
Sashes move vertically for ventilation and a traditional appearance. Single-hung windows have one operating sash; double-hung windows have two.
Picture
Fixed glass that does not open. Suits rooms where the view and daylight are priorities, or can be paired with opening windows for airflow.
Bay & Bow
Multiple window units project beyond the exterior wall, adding depth and a wider view. Selected units can open for ventilation.

Before & After: Bay Window Installation
This GNHE project shows an existing flat window replaced with a projecting bay. The before-and-after photos show how the new configuration changes the appearance of the home.
BeforeStarting With the Existing Window
The existing unit first had to be removed so the opening could be prepared for a window configuration that would extend beyond the exterior wall.
Completed
Building Out the New Configuration
The finished bay extends outward from the home. Supporting the projection and completing the weather sealing and exterior finish are part of the installation.
A new configuration needs a clear installation plan.

Welland Window Replacement FAQs
Answers about pricing, installation methods, permits, measurements and warranty coverage.
How much does window replacement cost in Welland?
The cost depends on the number and size of the windows, the configuration selected, the condition of the existing openings and how much installation and finishing work is required. GNHE measures the windows and reviews the project scope before providing written pricing rather than applying one standard price to every opening.
How do I know whether retrofit or full-frame replacement is right for my windows?
The decision starts with the condition of the existing window and surrounding materials. Retrofit may be suitable where the frame can remain in place and the existing finishes are worth preserving. Full-frame replacement exposes more of the opening and can be the better choice where deterioration, previous installation issues or planned finishing changes need to be addressed.
Do I need a building permit to replace windows in Welland?
Permit requirements depend on the work being completed. Replacing a window within the existing opening is different from enlarging, relocating or structurally changing that opening. If the wall, header or opening dimensions will be altered—or if the scope is uncertain—check the official City of Welland building permit information before the project begins.
What should be checked before replacement windows are ordered?
Measurements are only part of the assessment. GNHE also looks at the frame, sill, interior trim, exterior finish and the condition of the opening. Those details help determine the required window dimensions, installation method and finishing components before made-to-order windows are released for manufacturing.
What warranty comes with a GNHE window installation?
GNHE provides a five-year workmanship warranty for installation-related issues. The windows and applicable components are also covered according to the manufacturer warranty terms for the products included in the project.
