Our Window Services in Eau Claire, WI

Energy-Efficient Window Replacement
Nearly every older house in this city already carries two layers of glazing at each opening. Whether that adds up to an energy-efficient window depends on which decade paid for the second layer, and on whether the outer one still seals to its own track.

Vinyl Replacement Windows
Vinyl is the default answer in the Chippewa Valley and it deserves to be, on the right house. It is also the material most often installed here for the wrong reason, because it was the cheapest way to satisfy a closing deadline between 1985 and 2017.

Fiberglass and Composite Windows
Pultruded fiberglass is the material that behaves best when the temperature swings hard in both directions, which is the ordinary condition here rather than an unusual one. It costs more than vinyl and it earns that on specific openings rather than on a whole house.

Clad-Wood Windows
Clad wood is the right answer for a lumber-era house you intend to keep, and the wrong answer for a house you intend to rent. That sentence decides more Eau Claire quotes than any specification on the sheet, so we put it at the top rather than the bottom.

Aluminum Windows and Storm Panels
Two very different products share this name in Eau Claire, and confusing them is how people end up disappointed. There is the aluminum prime window, which almost never belongs in a heated Wisconsin house, and there is the aluminum triple-track storm, which is on thousands of them.

Double-Hung Windows
The double-hung is the signature opening of this city's older neighborhoods, and the version you have is probably a box frame: two sash running in a channel, cords over pulleys, iron counterweights hanging in a hollow pocket built into the jamb on both sides. That pocket is the whole argument.

Casement and Awning Windows
A casement shuts by compression. Its sash swings in against a continuous gasket and the crank pulls it tight, which is a fundamentally better joint than two sash sliding past each other on felt.

Sliding and Gliding Windows
The horizontal slider is the signature window of everything built here after about 1975: the ranch and split-level stock in Altoona, the subdivisions off Highway 53 toward Lake Hallie, and most of the two-story apartment blocks put up around the same years. Understand what you own.

Bay and Bow Windows
Treat a bay as a small addition rather than as a window. It is framed, floored, roofed and insulated like one, and here it fails on those terms long before the glass gives any trouble.

Picture and Architectural Glass
Fixed glass is the cheapest daylight you can buy. No balance, no operator, no weatherstrip to wear out, and no joint that can be left open in a rainstorm.

Basement Egress Windows
The question of whether a bedroom has a second way out gets asked in this city by the Health Department, not by a building inspector. Rental properties register with that department, and the city housing inspection program surveys homes on a five-year cycle, owner-occupied ones included.

Laminated and Security Glass
Wisconsin has no wind-borne debris region and Eau Claire County is nowhere near one. Nothing in the code here asks a window to survive a flying two-by-four, and anyone quoting hurricane-rated glazing in the Chippewa Valley is selling a specification you cannot use.

Patio Sliding Doors
Patio doors got named directly in the old transfer standard. SPS 367.11 (2) (c) required them to be insulated, double-glazed or fitted with a storm door, which is why so many older Eau Claire decks still have a second door hung outside the first one.

French and Atrium Doors
A french door is a pair of doors sharing one opening, sealed at the middle by an astragal rather than a frame. That center joint is the engineering problem, and in real wind and real cold it decides whether the door was worth buying.

Entry Doors and Storm Doors
The old transfer standard reached front doors too. Where no vestibule existed, an inward-swinging exterior door had to be insulated, double-glazed or fitted with a storm door, and every storm door had to be self-closing.

Screens and Combination Storm Units
In most of the country a screen is a bug barrier. Here a great many of them are one half of a triple-track combination unit, so the same frame carries a glass storm panel for seven months of the year and does a thermal job.

Glass Repair and Sealed Unit Replacement
Fogged glass is a seal failure, not a glass failure. The sealed unit is two panes bonded around a spacer holding a desiccant, and when that perimeter seal loses its grip, humid air pumps through it on every temperature swing, the desiccant fills up, and the inner faces begin to mist.

Commercial Storefront Glass
The old rental weatherization standard carved out an explicit exemption for storefront windows: they were not required to be double-glazed. That one clause is why the ground floor of a good deal of older commercial property in this city is still single-glazed, decades after the housing above it was upgraded.

Energy-Efficient Window Replacement
Nearly every older house in this city already carries two layers of glazing at each opening. Whether that adds up to an energy-efficient window depends on which decade paid for the second layer, and on whether the outer one still seals to its own track. From 1985 until the end of 2017, a Wisconsin rental could not change hands until somebody signed for its weatherization.

Aluminum Windows and Storm Panels
Two very different products share this name in Eau Claire, and confusing them is how people end up disappointed.

Double-Hung Windows
The double-hung is the signature opening of this city's older neighborhoods, and the version you have is probably a box frame: two sash running in a channel, cords over pulleys, iron counterweights hanging in a hollow pocket built into the jamb on both sides. That pocket is the whole argument. It is a void inside the wall assembly, open to the sash channel, usually uninsulated, and on a windy night it is a chimney running the height of the opening.

Casement and Awning Windows
A casement shuts by compression. Its sash swings in against a continuous gasket and the crank pulls it tight, which is a fundamentally better joint than two sash sliding past each other on felt. In a heating-dominated valley that difference is worth real money.

The horizontal slider is the signature window of everything built here after about 1975: the ranch and split-level stock in Altoona, the subdivisions off Highway 53 toward Lake Hallie, and most of the two-story apartment blocks put up around the same years. Understand what you own. A slider seals along a sliding track with a brush or fin weatherstrip, which is the weakest joint in common use.

Picture and Architectural Glass
Fixed glass is the cheapest daylight you can buy. No balance, no operator, no weatherstrip to wear out, and no joint that can be left open in a rainstorm. Used deliberately it lets you buy more glass, and better glass, for the same money.

Laminated and Security Glass
Wisconsin has no wind-borne debris region and Eau Claire County is nowhere near one. Nothing in the code here asks a window to survive a flying two-by-four, and anyone quoting hurricane-rated glazing in the Chippewa Valley is selling a specification you cannot use. That said, the glass those ratings are built on is laminated glass, and laminated glass is genuinely useful here for two reasons that have nothing to do with wind.

SPS 367.11 (2) (c) required them to be insulated, double-glazed or fitted with a storm door, which is why so many older Eau Claire decks still have a second door hung outside the first one.

French and Atrium Doors
A french door is a pair of doors sharing one opening, sealed at the middle by an astragal rather than a frame. That center joint is the engineering problem, and in real wind and real cold it decides whether the door was worth buying. Get the swing direction right first.

Entry Doors and Storm Doors
The old transfer standard reached front doors too. Where no vestibule existed, an inward-swinging exterior door had to be insulated, double-glazed or fitted with a storm door, and every storm door had to be self-closing. That clause put an aluminum storm on a great many Eau Claire porches.

Screens and Combination Storm Units
In most of the country a screen is a bug barrier. Here a great many of them are one half of a triple-track combination unit, so the same frame carries a glass storm panel for seven months of the year and does a thermal job. That is a direct legacy of how rentals were weatherized here.

Glass Repair and Sealed Unit Replacement
Fogged glass is a seal failure, not a glass failure. The sealed unit is two panes bonded around a spacer holding a desiccant, and when that perimeter seal loses its grip, humid air pumps through it on every temperature swing, the desiccant fills up, and the inner faces begin to mist.
What you should do about it depends almost entirely on what the sash is, and the two cases we see most often point in opposite directions from the usual advice.

Commercial Storefront Glass
The old rental weatherization standard carved out an explicit exemption for storefront windows: they were not required to be double-glazed. That one clause is why the ground floor of a good deal of older commercial property in this city is still single-glazed, decades after the housing above it was upgraded.

What Eau Claire property owners ask us
Which window services does Eau Claire Window Replacement handle?
Everything listed on this page, residential and commercial, across Eau Claire and Eau Claire County and the Chippewa Valley. Work is done by our own crews rather than handed to whoever is cheapest that week, which is the only way the workmanship warranty means anything.
Can I combine more than one service in a single job?
Yes, and it is usually cheaper. Bundling window work into one mobilization saves setup, disposal and travel, and it means one crew, one schedule and one written free estimate instead of three contractors blaming each other.
Do you give free estimates for every service?
Every one. We come out, measure, look at the real condition of the work area, and put an itemized free estimate in writing with materials and scope spelled out. No charge, no deposit, and no obligation to book.
What Eau Claire Customers Say
They surveyed all nineteen openings and came back saying five needed replacing and the rest needed the storms rebuilt and the sills sealed. Two other companies had quoted the whole house. The sheet listed every window with a reason next to it, and the final bill was less than a third of the other bids.
Basement bedroom for our daughter, and the wall turned out to be rubble stone. They walked us through the header, the well and where the drain had to tie in before anything was ordered. It took longer than we hoped and it was done right, which is what we wanted from that particular job.
Our 1907 house still has the original sash upstairs and I did not want them thrown out. They reglazed six of them, rebuilt the storms, and replaced only the two on the west wall that were past saving. Nobody else we called was willing to have that conversation at all.
Patio door had rotted the framing under the track and nobody had caught it. They pulled it, showed us the rim joist, fixed the framing and set the new door on a proper pan. Explained why the deck sitting level with the threshold was what caused it in the first place.
