Window Sash & Balance Repair in Atherton

Identify the window and describe whether the sash drops, sticks or is difficult to move. Ask which balance components have been assessed, how proposed replacements will be matched to the sash, and whether work on one or both sides is included. Agree on a completion check of sash movement and support, with any separate frame or hardware work itemized.

The scope depends on the condition, access and parts needed. Ask for a written quote for window sash & balance repair, including any callout charge, before authorizing work. Prices are not published on these pages; ask for the written quote.

Describe the issue: The window slams shut, will not stay open, or one corner of the sash sits lower than the other. Have your address, relevant model or hardware details and any previous work records ready.

Confirm availability and the expected time on site when you contact the provider. Access, diagnosis and parts availability can affect the appointment; this page does not promise an arrival time.

Ask which of these are part of the proposed scope: channel or spiral balances, balance shoes, pivot bars, sash cords, pulleys, sash stops. Confirm exclusions and the completion check in writing.

A balance helps maintain the position of the movable sash. Andersen describes that role for its Narroline balancers. A dropping or difficult sash still needs assessment to identify the affected components.

For its 200 Series Narroline windows, Andersen separates tempered and non-tempered glass and uses visible glass dimensions to select a balancer. Ask the provider to use the matching process for your particular window.

That depends on the identified system and repair scope. Andersen recommends both balancers and side jamb liners for the Narroline product described in its guide. Have the provider explain the recommendation for your model instead of applying that example universally.

Ask which sash was repaired, which components were retained, and how sash movement and support were checked. Keep the replacement identification and any remaining alignment or frame concerns with the repair record.
