When reviewing window replacement quotes, ask every installer to detail possible extra fees. For windows and doors ottawa clarify if costs include old window disposal, site cleanup, and trim or finishing work. Check for structural repair fees in case framing or insulation needs fixing, plus permit or inspection charges. Confirm whether hardware upgrades or custom colours cost extra, and if upper-floor or large window installations require additional labour. Getting every potential expense itemised upfront lets you compare providers accurately and prevents unpleasant surprises once the project starts — transparency ensures true value for your investment.
