ES Windows Home Additions & ADU: The Fresno Owner’s Guide
If you’re planning a home addition or ADU in Fresno and want ES Windows specified for the project, our team handles the full scope of work: framing, drywall, window installation with proper flashing, and final trim. Most Fresno home additions we build range from $45,000 to $130,000, with window packages for ES Windows products typically accounting for $8,000 to $25,000 of that total depending on the number of openings and glass options you choose. We give you a written price before any work starts, so the window line item is never a surprise later.
Homeowners usually start this conversation with us two ways. Either they’re adding square footage and know they want ES Windows but aren’t sure which series fits the project, or they have an existing addition with ES Windows already installed and one or more units need replacing because of fogged glass, a failed seal, or a crank mechanism that’s given up. Both paths lead to the same place: a window decision that affects how the room feels in July and January. Fresno summers push 105°F and winter nights dip below freezing, so the glass package matters more than the frame color. We’ll walk through that with you, but first let’s get the compatibility details straight.
Which ES Windows Models This Applies To

ES Windows builds vinyl and aluminum window lines in a range of series, and the one you have or want changes how we approach the opening. The most common ones we see in Fresno additions are the ES-1000 single hung, the ES-2000 slider, and the ES-3000 casement/awning series. Each uses different frame depths and glass packages, so an existing opening sized for an ES-2000 slider typically won’t accept an ES-3000 casement without frame modification. That’s a compatibility gotcha worth knowing before you order anything.
To identify what you have, look for a small white or silver sticker on the inside frame edge, usually on the left or right jamb. It lists the series number, the manufacturing date, and sometimes the glass type. If the sticker’s gone or faded, measure the visible glass width and height, then add roughly 3-1/4 inches to each dimension to estimate the frame size. When it comes to OEM versus aftermarket parts for ES Windows hardware (cranks, locks, balances), we always start with OEM because the tolerances on the locking points and operator arms are tight, and a generic replacement often binds within a year. For glass itself, high-quality aftermarket insulated units are fine as long as the spacer and low-E coating match the original spec, and we’ll tell you exactly how to verify that on the label.

Signs Your ES Windows Home Additions & ADU Is Failing
- Fog between the glass panes. This means the insulated glass unit has lost its seal. In Fresno’s heat, the argon or krypton gas between panes expands and contracts through seasons, and after enough cycles the perimeter seal fails and lets moisture in. The window still works, but you’ve lost the thermal performance you paid for.
- A crank that turns without moving the sash. On ES-3000 casement models, the operator arm gear teeth wear down or the hinge rivets loosen, and suddenly the handle spins freely. This is a hardware failure, not a frame failure, and the fix is usually a new operator assembly rather than a whole window.
- Difficulty lifting or holding the sash up. On single hung units, the balance system inside the jamb does the heavy lifting. When the spring tension gives out, the sash either drops shut or won’t stay raised. Fresno dust doesn’t help: it works into the balance channels and accelerates wear.
- Drafts you can feel around the frame on windy days. The weatherstripping on vinyl windows compresses over time, especially on the south and west sides of the house where afternoon sun beats on the frame. A draft usually means the weatherstripping has flat spots or the sash alignment has shifted slightly out of square.
- Condensation between the sash and frame, not just on the glass. This points to an air leak at the interlock or the sweep, not a failed glass seal. It’s often fixable with new weatherstripping and a sash adjustment, and we’d rather check that first than sell you a window you don’t need.
Replacement Cost & What’s Included

For an ES Windows home addition or ADU in Fresno, here’s the pricing breakdown you can expect:
- Full home addition (framing through finish, including ES Windows packages): $45,000 – $130,000
- ADU construction (detached, permitted, with ES Windows): $90,000 – $220,000
- Garage conversion (with new ES Windows where required by code): $30,000 – $80,000
- Window replacement only (ES Windows, multiple openings in an existing addition): $4,500 – $15,000
- Impact window installation (per ES Windows impact-rated package, where specified): $8,000 – $25,000
What drives the spread on an addition is mainly square footage, foundation condition, and how much electrical and HVAC work the project pulls in. Window cost per opening is fairly predictable once we count the units and pick the glass package. Every line is written down before work starts, so you’re not getting an estimate that grows after the crew arrives. Our 365-Day Done Right Promise covers the completed project: if something isn’t done right, we make it right. That includes the window flashing, the trim, and the drywall returns around the openings.

You can safely check a few things yourself: look for the sticker on the frame to get the series number, measure the visible glass, and note whether the issue is fog, drafts, or hardware. That information helps us quote the job accurately over the phone. What you shouldn’t do is remove a window sash or try to replace a balance or operator arm without knowing how the tension and fasteners work on that specific series. Vinyl frames crack when you force a screw into the wrong spot, and a casement sash under spring tension can pinch hard if it releases unexpectedly. If the job involves removing the window from the frame, let a trained professional do it.
Most ES Windows hardware swaps take us under an hour per window once we have the right part in hand. If you’re in Fresno and want us to look at what’s failing, call (559) 540-8453 and we’ll schedule a time. Graham keeps a written list of every issue you mention so nothing gets lost between the phone call and the site visit.
FAQs

With proper installation and occasional weatherstripping replacement, ES Windows vinyl frames typically perform well for 20 to 30 years in Fresno, though the glass seals often fail between years 10 and 20 on sun-exposed walls. The frame itself rarely needs replacing; it’s usually the insulated glass unit or the hardware that goes first. Call (559) 540-8453 for a window-by-window assessment, and we’ll tell you which units are failing and which still have life left.
Yes. If the frame is sound and the sash operates correctly, we can replace just the insulated glass unit while keeping the original vinyl frame, which costs less than a full window replacement. The new glass unit gets ordered to the exact original dimensions, and we verify the low-E coating spec before it’s installed. Call us for a quote on glass-only replacement: (559) 540-8453.
For a single ES Windows replacement, the install usually takes 60 to 90 minutes including trim removal, shimming, leveling, and re-caulking. Multiple windows in one addition can usually be done in a single day. For a full home addition or ADU with new ES Windows, the window phase typically lands inside a broader 2 to 4 month construction schedule. We’ll give you a written timeline before work starts.
We stock common ES Windows hardware like operator arms, locks, and balances on the truck, and we order glass units and full windows to the exact opening size before we arrive. For series-specific parts that aren’t in the truck, we can usually have them within a few business days. Call (559) 540-8453 and tell us your series number, and we’ll confirm what we can bring same-week.
