Window Repair and Replacement Cost for Handymen
Price window repairs at $75–$200 for hardware fixes (locks, balances, weatherstripping), $150–$350 for single-pane glass replacement, and $200–$500 for double-pane IGU (insulated glass unit) replacement. Full window replacement runs $300–$600 per window for vinyl insert windows. Screen repair or replacement costs $25–$75 per screen. Set a minimum service charge of $150.
Window repair is a profitable niche for handymen because most window problems do not require full replacement — they need targeted repairs that homeowners cannot easily do themselves. A stuck window, a broken balance, a failed seal, or a cracked pane can often be fixed for a fraction of the cost of a new window. Knowing when to repair versus replace — and pricing each accordingly — makes window work a reliable revenue source.
Window Hardware Repair Pricing
Window hardware repairs are fast, high-margin jobs. Replacing window locks and latches costs $50–$100 per window — the hardware itself is $10–$25 (Truth Hardware, Prime-Line, and Barton Kramer are common replacement brands available at Home Depot), and installation takes 15–30 minutes. Replacing broken window balances (the spring mechanisms that hold sash windows up) runs $75–$150 per window. Balance types include block-and-tackle, spiral, and channel balances — identify the type before ordering parts. Operator handles and cranks for casement windows cost $50–$100 to replace. Worn or missing window locks on double-hung windows are $30–$60 per window. When quoting hardware repairs, inspect all windows in the home — if one balance is broken, others are likely worn. Offer a per-window discount for multiple repairs: $75 for one window, $60 each for 3+.
Glass Replacement: Single-Pane and Double-Pane
Single-pane glass replacement is a traditional handyman skill. Remove the broken glass, clean the frame, apply new glazing points and glazing compound (DAP 33 or Sarco Dual Glaze at $8–$15), and set the new glass. Charge $150–$250 per pane for standard sizes (up to 24x36 inches). The glass itself costs $20–$60 per pane from a local glass shop — always have them cut to your exact measurements minus 1/8 inch for expansion. Double-pane insulated glass units (IGUs) that have failed seals (you see fog or condensation between the panes) can be replaced without replacing the entire window sash. IGU replacement runs $200–$500 per window depending on size and glass type. Order the replacement IGU from a local glass fabricator — measure the exact dimensions and glass type (clear, Low-E, argon-filled). Turnaround is typically 3–7 business days. The swap takes 30–60 minutes per window.
Window Weatherstripping and Sealing
Window weatherstripping replacement improves energy efficiency and is an easy add-on to any window repair visit. Charge $25–$50 per window for weatherstripping replacement. Common types include V-strip (bronze or vinyl, $5–$15 per roll), foam tape ($3–$8 per roll), and compression strips ($8–$15 per window kit). For double-hung windows, replace the weatherstripping on both the meeting rail and the channels where the sash slides. Tubular gasket weatherstripping works well for casement windows. The total material cost per window is $3–$10, making this a high-margin service. Bundle weatherstripping with other window repairs or offer a whole-house weatherstripping service — 10 windows at $30 each is $300 for about 2 hours of work. See weatherstripping-and-insulation-pricing for more details on energy efficiency services.
Full Window Replacement
Full window replacement is at the upper end of handyman scope. Insert (pocket) window replacement — where a new window is installed inside the existing frame without disturbing interior or exterior trim — is well within handyman capability. Vinyl insert windows from brands like Pella 250, Andersen 100 Series, or Jeld-Wen V-2500 cost $150–$400 per window. Charge $150–$250 per window for installation labor, making the total $300–$600 per window installed. The process involves removing the sash and parting stops, measuring for the insert, applying a bead of siliconized caulk on the sill, setting the new window, shimming for plumb and level, insulating the gap with low-expansion foam, and applying interior trim. Budget 1–2 hours per window. For full-frame replacement (removing the entire window including the frame and exterior trim), refer to a window contractor — this involves exterior finish work, flashing, and potential siding modification.
Storm Window Installation and Repair
Storm windows are a cost-effective alternative to full window replacement for improving energy efficiency. Interior storm window kits from Indow, WindowSeal, or Duck Brand cost $30–$100 per window for materials. Installation runs $50–$100 per window — measure the window opening, cut or order the storm window insert, and secure it in place with compression tubes, magnetic strips, or mounting clips. Exterior aluminum storm windows cost $75–$200 per window and take 30–60 minutes each to install. For existing storm windows needing repair — broken glass, torn screens, or failed hardware — charge $50–$125 per window. Storm window screen-to-glass panel swaps (seasonal changeover) can be offered as a spring/fall service at $15–$25 per window for clients who do not want to climb ladders.
Estimating Tips for Window Jobs
Window work requires careful pre-job assessment. Always visit the site before quoting anything beyond basic hardware repairs — window sizes, types, and conditions vary enormously. Measure each window precisely for glass or IGU orders — a 1/4-inch error means a wasted trip and reorder. Identify the window manufacturer and series if possible (look for stamps on the hardware, spacer bars, or frame) so you can order correct replacement parts. For older homes with wood windows, check for lead paint — pre-1978 homes may have lead paint on window frames, which requires specific handling under EPA RRP rules. If you are not RRP certified, factor in whether the repair disturbs painted surfaces. Common estimation mistakes include underestimating the number of coats of paint holding a window shut, not accounting for rotted sills or frames discovered during repair, and forgetting to include the cost of interior and exterior trim touch-up.
Frequently Asked Questions
Repair is almost always cheaper for single issues. A broken balance repair ($75–$150) versus a new window ($300–$600) saves the client 50–75%. A failed IGU replacement ($200–$500) versus a new window saves 30–50%. Recommend replacement only when multiple components have failed, the frame is rotted, or the window is so outdated that repair parts are unavailable.
