A window quote should explain what is being replaced, how the opening will be finished, and what is included.
EXISTING FRAME RETAINED
A replacement unit fits within a suitable existing frame. This can preserve surrounding trim and reduce disruption, but the retained frame must be sound and the glass area may be smaller.
Worth discussing when: the existing frame is in good condition and keeping the trim matters to you.
FRAME REMOVED
The existing window and frame are removed so the opening can be assessed. The scope includes planning the new window, weather protection, and interior and exterior finishing.
Worth discussing when: there is frame deterioration, a change in style, or a need to address the surrounding opening.
The best approach depends on an inspection of your existing windows and the chosen product.
BEFORE YOU COMPARE QUOTES
Window count is only the starting point. Compare the same products and scope to understand what each estimate covers.
Window dimensions, operating style, frame material, glass package, and color all affect the price.
Insert or full-frame installation, access, trim, exterior capping, and any opening repairs change the scope.
Ask each contractor to identify removal, disposal, finishing, payment terms, and product and labor warranty coverage in writing.

A name with a place in our hearts.

GOOD QUESTIONS. CLEAR ANSWERS.
A few practical answers to help you plan your project.
We provide supply-and-install replacement projects using products ordered through our suppliers. We do not install customer-purchased windows or patio doors. This lets us coordinate product specifications, ordering, and installation from the start.
No. You can discuss a few problem windows, one room, or a whole-home project. Let us know which windows have drafts, fogging between panes, trouble opening, or visible frame damage.
An accurate estimate depends on measurements, product selection, installation method, and the condition of the opening. Share your town, approximate window count, and what you want to change as a starting point.
Products are sourced through suppliers. Ask for the specific manufacturer, model, glass package, manufacturer warranty, and any installation coverage in your proposal before making a decision. Coverage depends on the product and written terms.
Product lead times and installation time are separate. Both depend on the order, window count, access, and scope of work. Confirm the expected schedule and any possible delays when reviewing your project.
