"Elvin is great. He fixed my wood double front doors and applied paint that I had picked out, as well as new handles/lock. He took his time, was very polite, and made sure everything was in order before in left. My front doors look amazing. Will be hiring him again for more work around the house. Also, his pricing was very reasonable and on point for the amount of repair and painting work he did."

"Rafael was great - he fixed our front door knob and lock, replaced another door handle, and our towel bar. He worked us into his busy schedule and came by on a day that was best for me. Rafael picked up parts he needed at Home Depot after assessing what we needed, and efficiently completed all three jobs."

Window Door Contractors FAQs, answered by experts

Tears, holes, or difficulty in opening and closing suggest a need for repair.

Window seals don’t last forever, so they’ll inevitably fail for one reason or another. One of the most common reasons is the expansion and contraction of the glass. When the glass gets warm from sunlight, it expands and adds pressure to the seal; at night, as the glass cools, it contracts. This process, day in and day out, can eventually cause the seal to fail. Other common sources of failure include the house settling over time, chemicals that damage the seal when repainting windows, and incorrect window installation.

Drafts, condensation between panes, difficulty operating, or visible frames or glass damage are signs of needed repairs.

The average cost to repair a window is about $400, with prices typically ranging from $175 to $1,500. The final cost is influenced by several factors, including:

  • Number of Panes: Single-pane repairs average around $200, double-pane repairs range from $200 to $400, and triple-pane repairs can cost $600 to $1,100.

  • Type of Repair: Minor fixes for a track, seal, or sash are more affordable than repairs for broken glass or window frames, which are typically the most expensive.

  • Window Details: The size, type, and material of the window affect the price.

  • Accessibility: Windows on upper floors or in hard-to-reach locations may increase labor costs.

  • Other Factors: The extent of the damage, local labor rates, and the need for emergency service will also impact the total cost.

For comparison, a full window replacement can range from $175 to $1,800 or more for high-end materials or large windows like bay or bow windows.

Screen repair is always worthwhile, as tears and holes in your windows and door screens are unsightly and allow pests and debris into your home, rendering the screen useless. The faster you repair your screens, the faster you can open your windows and doors freely to let the fresh air in. Consider repairing multiple door and window screens during one appointment with a screen repair technician to make the investment and labor costs worth it.
