Show us the existing openings
Send your address, the number of windows and photos from inside and outside. Approximate sizes help start a quote; have your own installer confirm the final manufacturing dimensions.

Identify unchanged openings and proposed alterations
London’s building-permit guidance separates same-size replacement windows and doors from new or enlarged openings. Mark the distinction on your opening list and include any changes to framing or the surrounding wall. Have your project professional confirm the complete work scope with the City before selecting manufacturing sizes for an altered opening.
City of London building permit guidanceTreat basement renovation as a complete project
A basement window order may be part of a larger change in room use, walls or foundation openings. London’s homeowner guidance identifies basement finishing and these associated alterations as work requiring permit review. Share the proposed room layout and the clear-opening or glazing specifications from your designer. Product selection alone does not establish that the finished renovation meets its requirements.
London basement and homeowner project guidanceCheck the property’s heritage designation
London distinguishes listed properties, individually designated properties and properties within Heritage Conservation Districts. Check the address through the City’s heritage resources and discuss work affecting protected attributes with a Heritage Planner. District alteration requirements depend on the applicable plan. Resolve whether repair, retention or a particular replacement design is appropriate before approving materials for an order.
London heritage property and designation resourcesCompare the windows room by room
Record fixed and opening sections, frame colour, glass privacy and the dimensions used for each comparison. Ask for performance information for the complete proposed window rather than a glass label alone. Photograph grouped openings, projecting windows and trim conditions. Keep the accepted operation and glass choices together so a change in one room is not copied across the whole order unintentionally.
Compare replacement window configurationsDescribe doors and installation work clearly
Include full entry-door assemblies, sidelites and transoms, or the panel layout for a sliding patio door. Ask the quote to identify products, delivery and any removal, repairs, sealing or finishing included. Have the installer confirm the replacement method and final dimensions. Supply-only orders are available if your own contractor will receive and install the products.

Window replacement questions in London
Is this page for London, Ontario?
Yes. Include your London, Ontario address and postal code with the quote request so the project location and available delivery or installation arrangements can be confirmed.
Can a same-size window replacement be part of permitted work?
Yes. Even where the City lists same-size replacement as not requiring a building permit by itself, a basement renovation, structural alteration or larger project can have separate requirements. Confirm the complete proposal.
What should I check for a London heritage property?
Confirm whether the property is listed, individually designated or in a designated district. Consult City heritage staff about protected attributes and the applicable plan before selecting materials or changing openings.
Can I review a London project without visiting the showroom?
Yes. Book a virtual appointment and send opening photos, approximate dimensions and any plans or specifications. Final measuring, product choices and address-specific delivery or installation arrangements still need confirmation before ordering.
