Replacement Windows in Madison

We do not install, measure or inspect windows. We pass requests to independent local contractors.

What Madison houses are like

• The isthmus and near-east and near-west neighbourhoods are largely pre-1940: foursquares, bungalows, Queen Anne cottages and early duplexes. Original windows here are typically wood double-hung, often with divided upper sash, and exterior storm windows added later. Interior casing and plaster returns are frequently original and worth protecting during installation.
• A student and tenant rental market near the university, which means many buildings have been through at least one earlier round of cheap replacement windows. Those 1980s and 1990s units are now at the end of their service life, and their sealed units and hardware are often no longer supported.
• The 1950s to 1970s ring, west and north: ranches and split-levels, originally with wood or aluminum double-hung and sliding units, plus the picture-window-plus-flankers arrangement typical of the period.
• The far west, far east and newer suburbs, where houses tend to have factory-built casements and double-hung units from the 1990s onward, often vinyl or clad wood, now reaching the age where sealed units start to fog.
• Lake-adjacent properties on Mendota and Monona, where large glazed areas facing open water make glass surface temperature and air sealing matter more than elsewhere.

Practical consequences: on the pre-war ring, ask whether the quote is insert or full-frame and what happens to the interior trim. On the 1990s ring, ask whether the existing insulated glass unit can be replaced on its own, which is often cheaper than a whole window.

Permits in Madison

Building Inspection, part of the city's Department of Planning, Community and Economic Development, handles permits and inspections in Madison [M2].

Wisconsin DSPS treats replacing windows with equivalent units as a "repair", exempt from the Uniform Dwelling Code, but a municipality may still require a building permit for a repair by ordinance [W4]. Madison's requirements are Madison's to state, so ask them about your job before you order. Note too that Madison has local historic districts, which can regulate appearance separately from the building code.

Our window permits page has the questions to ask.

Costs

We print no Wisconsin per-window average, because no source is good enough. For a benchmark: a 2026 This Old House survey of 1,000 homeowners put the national average at $517 per installed window and the average total project at $7,183 [W1]. A national survey average, not a Madison price and not a quote.

What tends to move a Madison quote: whether the job is insert or full-frame, interior trim on pre-war houses, upper-storey access on foursquares, large lake-facing glazed areas, and lead-safe work practices on pre-1978 homes. Read the cost guide or try the calculator.

Rebate

The Focus on Energy windows rebate is statewide and comes with strict conditions: a reservation approved before purchase, submitted by a participating Trade Ally contractor, purchase and installation between June 1, 2026 and December 15, 2026 while funds last, ENERGY STAR Version 7 Northern Climate Certified units, and at least 51% of heating from a participating electric or natural gas utility [W2]. Rental properties should check the eligibility terms carefully: the programme covers an existing single-family home or a dwelling of three or fewer units [W2].

If you are starting now, ask the contractor whether a before-purchase reservation and an installation completed by December 15, 2026 is still achievable. 2027 terms were not published as of November 13, 2026. Confirm current terms with Focus on Energy on 800.762.7077. See the rebate page.

Request quotes in Madison

Tell us about your windows and we will pass the request to an independent contractor serving Madison and Dane County, who may contact you about it. There is no cost, and we cannot promise anyone will contact you or when.

Request window quotes, call (414) 677-7697 or text us at (414) 677-7697. That is the number for this site, which covers all of Wisconsin, not a local Madison line. Calls may be recorded; see our privacy notice.

A referral is not an endorsement, so check any contractor yourself before you sign.

We're a referral service, not a contractor, and independent contractors may pay us for referrals.
