Commercial Windows in Federal Way

We replace and upgrade windows for offices, storefronts and small commercial buildings. We also help you plan the work in phases so it fits your budget and your hours. You get a clear scope, a written estimate and a schedule that keeps your doors open.

Window work for your building, planned on your terms

Commercial windows rarely fail all at once. It starts with a few fogged panes, a sash that won't latch, or a draft by the front counter. Then a tenant complains or a pane cracks, and you end up paying for rushed work at the worst possible time. We would rather help you see it coming.

On our first visit we walk the building, note every opening, and sort them into what needs attention now and what can safely wait a year or two. That gives you a phased plan you can put into a budget instead of one large surprise. We replace fixed and operable windows, storefront glass, and insulated glass units in existing frames.

Many low-rise offices and retail buildings around Federal Way still have their original aluminum frames with no thermal break. Those frames sweat through the wet months and pull heat straight out of the room. Newer frames and glass stop the condensation and can lower what you spend to heat and cool the space.

What our commercial window service covers

Building walk-through
We measure every window, note its condition and photograph problems so you can see what we saw. You get a written list by opening, not one lump number.
Phased replacement plans
If the whole building can't be done at once, we group the work by floor, by side of the building or by urgency. Each phase is priced on its own, so you approve it when the budget allows.
Glass-only replacement
When a frame is still sound, swapping a fogged or cracked insulated glass unit costs far less than a new window. We tell you plainly when that is the better choice.
Full frame replacement
For corroded, leaking or single-pane frames, we remove the old unit, repair what we find in the opening, and set new frames with proper flashing and sealant.
Safety glass and code checks
Glass near doors and walkways often has to be tempered, and replacement windows must meet the Washington State Energy Code. We check those requirements, and whether a permit is needed, before any work starts.

Signs your building's windows need attention

  • Fog between the panes

    A cloudy look you can't wipe away means the seal on the insulated unit has failed. The glass no longer insulates the way it should.

  • Water on sills and frames

    Older aluminum frames collect condensation on cold mornings. Over time that water stains drywall, swells trim and can lead to mold near the window.

  • Drafts and hot spots

    Staff who sit near the windows feel it first. If people are moving desks or running space heaters, your heating and cooling system is working harder than it needs to.

  • Windows that won't latch

    Worn hardware on operable windows is more than an annoyance. A window that won't lock is a security gap after hours.

  • Cracked or chipped glass

    Small cracks tend to grow as the glass heats and cools. Scheduling the fix now costs less than dealing with a broken pane during business hours.

  • Shrunken exterior sealant

    Cracked, pulled-away caulk joints let wind-driven rain into the wall. Once water is getting behind the frame, the repair gets bigger.

How a commercial window project runs

  1. 1

    A quick first call

    Tell us about the building and what you're seeing. We set a time to walk the site, and the quote is free.

  2. 2

    Site walk and written estimate

    We measure, photograph and list each opening with our recommendation. If phasing makes sense, the estimate shows each phase separately so you can decide what comes first.

  3. 3

    Ordering and scheduling

    Commercial glass and frames are usually made to order, so we set the install date once materials are confirmed. Together we agree on start times and which areas will be closed off.

  4. 4

    Installation

    We protect floors and fixtures near each opening and replace windows one section at a time. Each opening is closed up and sealed before we move on, so your space stays secure.

  5. 5

    Cleanup and final walk-through

    We clear away glass, old sealant and debris, haul off the old units, and walk the finished work with you before we leave.

What drives the cost of commercial windows

Every building is different, so we price from the walk-through rather than a per-window guess. Your estimate lists each opening, so you can see where the money goes and choose what to tackle first. We also offer flexible payment options, which helps when a project spans more than one budget year.

Number and size of openings
A row of large storefront panes takes more glass, more labor and more handling than a few office windows.
Glass type
Tempered, laminated, low-E and tinted glass each cost differently. Code may require safety glass in some locations, and that is built into the price.
What's behind the frame
Corrosion, rot or water damage in the opening has to be repaired before a new window goes in. We show you photos of anything we find.
Access and height
Ground-floor windows are straightforward. Upper floors may need lifts or extra setup, which adds time.
Scheduling and phasing
Work outside normal hours or spread across several visits adds some setup cost, but it often saves you more in avoided downtime.

Commercial window questions

Something not covered here? (253) 313-7629

Can you work while our business is open?

Usually, yes. We replace windows one section at a time and close off only the area we're working in. If a space needs to stay fully open, we can talk through earlier start times or splitting the job across days.

Do we have to replace every window at once?

No. Most owners phase the work, starting with failed or leaking units and leaving sound ones for later. Our estimate breaks the building into phases so you can approve each one when it fits your budget.

Is replacing just the glass worth it?

If the frame is solid and draining properly, a new insulated glass unit is often the smart, lower-cost fix. If the frame itself is corroded or leaking, new glass won't solve the problem, and we'll say so.

Does commercial window replacement need a permit?

It depends on the scope. Changes to the size of an opening or large replacements often do. We check with the city before work begins and pull the permit when one is required.

How long does a project take?

Most installs are finished in a single day. Larger buildings or phased projects run over several planned visits, and you'll know the schedule before we start.

Do you work outside Federal Way?

Yes. We also take on commercial window projects in Kent, Auburn, Des Moines, Fife and Tacoma, along with other nearby communities.
