Double-Hung Window Replacement in Los Altos Hills

Clarify whether the proposal replaces the sashes, installs an insert or removes the complete frame. Ask which balances, locks and other hardware are included and whether any existing components remain. Agree on the finishing scope and a completion check covering the operation of both sashes and the selected tilt features, where fitted.

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

Describe the issue: The top and bottom panels rattle, drift out of place, and leave a draft where they meet in the middle. 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: double-hung frame, upper sash, lower sash, balances, meeting-rail lock, weather seals, installation trim. Confirm exclusions and the completion check in writing.

Yes. Marvin describes double-hung windows with two operable sashes that move vertically. Have the proposed upper and lower sash operation demonstrated, including access to their controls at the intended location. A similar-looking product drawing does not replace confirmation of the actual window type and configuration.

No. Andersen’s parts catalog distinguishes non-tilting Narroline windows from Tilt-Wash models and identifies different cleaning features by product. Confirm the exact proposed model and its cleaning instructions. If tilt-in access matters, have that feature recorded and demonstrated for the supplied configuration rather than assuming it from the double-hung label.

Ask which components the proposal supplies or retains. Andersen describes balances as the mechanisms holding sashes in position. Have the cause of drifting assessed and the proposed balances, liners and hardware listed; the phrase sash replacement does not define those details.

Ask for both sashes to be operated and returned to their closed positions, with the meeting rails and supplied lock checked together. Have any uneven meeting point, sticking or remaining adjustment recorded for follow-up. Keep the instructions for operation and any fitted cleaning features with the product record.
