Trusted Windows & Doors for Denver Homeowners
Windows and doors in Denver take a beating that most cities never see. We’re talking about 300-plus days of high-altitude sun, swing temperatures of 40 degrees in a single afternoon, hail that cracks glass, and the freeze-thaw cycle that warps frames and destroys seals. The result is fogged double panes, drafts that spike heating bills from October through April, and doors that stick or leak when the snow melts. Our Windows & Doors in Denver service is built to address exactly these problems: measured, documented, priced in writing before any work begins, and backed by the Haven Standard’s five published clauses, including photographic evidence of what we find on every visit. Call (970) 725-6025 any time, day or night, and a live person answers.
What Our Windows & Doors Service Includes
Every home in Denver eventually needs window and door work. The question isn’t whether, it’s what kind and how soon. Here is what we handle under the Windows & Doors umbrella, with the same five Haven Standard clauses governing every job from a single fogged pane to a full replacement. The price is on the page in dollars before anyone arrives, the technician is named with a real arrival window, and the crew is licensed, insured, and background-checked with the license number published for you to verify.
Window Glass Replacement
A cracked or shattered pane is more than an eyesore in Denver; it’s an open channel for cold air that pushes your furnace to work overtime from the first hard freeze in October. We replace insulated glass units (IGUs) and single panes, matching the existing frame and glass package so the replacement is invisible to neighbors and HOA reviewers alike. Before recommending a swap, we measure the existing unit, check the spacer condition, and photograph the failure so you can see the cause, not just the symptom.
Window Seal Repair
That chalky fog between two panes means the seal has failed and the insulating gas is gone. In Denver’s altitude, a failed seal drops the window’s insulating value just when the temperature delta between indoors and outdoors is at its widest. We replace failed IGUs with new units that restore the original thermal performance, and we document the failure with photos before and after so the fix is verifiable on paper, not just by feel.
Exterior Door Replacement
A front or back door that swells in summer and shrinks in winter is not a quirk; it’s a fit problem that costs you conditioned air every day of the year. We install steel, fiberglass, and wood exterior doors sized and shimmed for Denver’s chronic dryness and winter moisture swings, with new weatherstripping and threshold seals included. Every installation starts with a written price and ends with photos of the completed work, including the reveal gaps around all four sides.
Sliding Glass Door Repair
Sliding doors that grind, stick, or refuse to latch are the most common door call we get in Denver, usually because the rollers have worn flat or the track has filled with decades of grit. We replace rollers, restore track alignment, and adjust the strike plate so the door locks fully, which also matters for your home insurance position. The fix is quoted before we touch a screwdriver, and you get a photo of the worn roller and the new one side by side.
Weatherstripping and Sealing
Air leakage around windows and doors accounts for a surprising share of Denver heating and cooling cost, especially in older Park Hill, Congress Park, and Virginia Village homes where original weatherstripping has turned to powder. We replace compression strips, door sweeps, and caulking with materials rated for Denver’s UV exposure and temperature swings, which cheap foam products cannot survive for more than a season or two. The improved seal is verifiable the first cold morning when the draft is simply gone.
Window and Door Hardware
Cranks that grind, latches that won’t catch, hinges that sag, and locks that need a shoulder to open are daily annoyances that become security problems if ignored. We replace and adjust casement operators, sash locks, deadbolts, and hinge hardware, and we match the finish so the repair looks factory. A quick photo of the old hardware removed and the new hardware installed goes into the job report, along with the original written price.

Brands We Service for Windows & Doors
Denver homes carry a wide mix of window and door brands, from Pella and Andersen on newer builds to Marvin, Milgard, and Jeld-Wen on mid-century and early-2000s stock, plus a long tail of builders’ grade brands like Cascade and Alpine. We service all of them. The Haven approach does not change with the nameplate: measure the existing unit, price the work in writing, and install a replacement that fits the existing opening without adapters or improvisation.
We’ve replaced more Andersen narroline double-hungs in Denver than any other single window type, and we stock the common IGU sizes for Pella and Marvin so a fogged seal is often a one-visit fix. Milgard’s Denver presence runs deep in the southeast metro, and we match their frame profiles and hardware finishes without making the homeowner hunt for a factory-authorized shop. Whether you have Andersen, Pella, Marvin, Milgard, or something else entirely, the window or door gets the same treatment: documented, priced in writing, and installed to Clause 1 of the Haven Standard with no upsell at the door.
Before
AfterSigns You Need Windows & Doors Right Now
- Fog or moisture trapped between the panes. A failed seal means the insulating gas is gone, and the window is now doing roughly what a single pane did in 1985. In Denver’s winter, that means frost on the inside of the glass and higher gas or electric bills from the furnace fighting the loss.
- Drafts you can feel around the frame with the window or door closed. If you can feel air move past the edge of a closed window on a cold day, the weatherstripping or the frame seal has failed. That leak is costing you money every single hour the heat runs.
- Difficulty opening, closing, or locking. A window that won’t stay up or a door that won’t latch is not annoying, it’s a safety and security problem. If you have one exit blocked by a stuck window or a door that cannot be locked, that’s a call worth making today.
- Visible rot, warping, or peeling finish on wood frames and sashes. Denver’s sun and snowmelt cycle is brutal on wood, and rot spreads once it starts. A soft corner today is a full frame replacement and water intrusion damage six months from now.
- Rising heating or cooling bills without a change in thermostat habits. Air leakage around window and door perimeters is one of the quietest, steadiest drains on a Denver home’s energy budget. If the bill climbs and the weather hasn’t changed, the envelope is leaking, and the windows and doors are usually where it starts.
Our Windows & Doors Process - Step by Step
Step 1: You call, a live person answers
No automated menu. No call center. The person who answers can book a time, confirm the address, and give you the real arrival window with a named technician. That’s Clause 2 of the Haven Standard, and it applies to every call we take in Denver, including the 2 a.m. ones.
Step 2: The technician arrives and documents everything
Your named technician shows up in the window, in uniform, and starts with a thorough inspection of the window or door you called about, plus a quick pass at the surrounding units so you know if a neighboring problem is about to happen. Every finding is photographed and time-stamped.
Step 3: You get a written price before any work starts
The price is on the page before a van is even dispatched, and the final number is quoted in writing when the inspection is done. If the inspection reveals something hidden, the updated price is agreed before a single tool comes out. No surprises, no “the office didn’t tell you” moments, no upsell at the door.
Step 4: The work is completed and photographed
The repair or replacement is done with the right materials for Denver’s climate, and the finished job is photographed as evidence. You get a report showing the before, the during, and the after, so what was promised and what was delivered are the same documented record.
Step 5: The 365-Day Done Right Promise applies
If the work is not done right, we make it right. The window is a full year, and the obligation is the same clause for a window seal in Denver as it is for a garage door in Birmingham or a chimney in Columbus. You hold the evidence, and we hold the standard.
How Much Does Windows & Doors Cost in Denver?
Here are the Denver market prices for the most common window and door jobs, in dollars, before you pick up the phone. A fogged double-pane window replacement typically runs $180 to $340 depending on the size of the IGU and the brand of the frame. Exterior door replacement in Denver usually lands between $700 and $2,200 depending on the door material, the condition of the rough opening, and whether new hardware and weatherstripping are included. Sliding glass door repairs like roller replacement and track work run $120 to $240, while full weatherstripping and sealing around a standard door or window is typically $120 to $250 per opening.
What moves the price in Denver specifically? Altitude. High-altitude IGUs with capillary tubes or breather tubes are often required for homes above certain elevations to keep the glass from bowing, and those units cost more than standard panes. The age and material of the frame matters too: replacing glass in a 1960s wood double-hung usually involves more prep work than a 2010 vinyl sash. And where the home sits, neighborhood by neighborhood, changes access and parking, which is part of why a Congress Park window replacement and a Highlands Ranch door install can quote out differently for the same unit.
The way to avoid overpaying is to know the price before you commit. The Haven Standard’s Clause 1 means you get the price in writing before work starts, and the free estimate gives you the number without any obligation. If someone won’t put the price on the page or in a written quote, that’s a signal worth paying attention to.

Frequently Asked Questions - Windows & Doors in Denver
Windows & Doors covers the inspection, repair, and replacement of residential windows, glass units, and exterior doors. That includes fogged double panes, failed seals, cracked glass, sticking doors, broken hardware, weatherstripping, and full door or window replacement. Every job in Denver is priced in writing before work starts, and every technician is licensed, insured, and background-checked under the Haven Standard.
Most individual pane replacements and door hardware repairs are completed in one visit of one to two hours. A full exterior door replacement or a multi-window job usually takes a half day to a full day depending on the complexity of the framing and the number of openings. When you book, you get a real arrival window with a named technician, not a four-hour spread.
The common Denver ranges are $180 to $340 for a fogged IGU replacement, $700 to $2,200 for an exterior door, and $120 to $240 for sliding door roller and track repair. The final number depends on the size, brand, and age of the unit, plus whether high-altitude glass is required. Call (970) 725-6025 for an exact quote - estimates are free and the price is in writing before any work begins.
Yes, we service Andersen, Pella, Marvin, Milgard, Jeld-Wen, and most other brands found in Denver homes. We stock common IGU sizes for Pella and Andersen so many fogged-seal replacements are a single visit. If your window or door is a brand not listed here, the same standard applies: measured, priced in writing, and documented with photos.
Yes. A shattered pane or a door that cannot lock is a security and weather emergency, and we respond same-day in the Denver metro. Calls are answered by a live person 24/7 at (970) 725-6025, and the person who answers can dispatch directly to the local independently owned and operated Denver crew.
Every window and door job performed under a Haven brand carries the 365-Day Done Right Promise. If the work is not done right, we make it right, for a full year. The guarantee is the same clause for a window pane in Denver as it is for a full ADU build in Austin, and it is published, not verbal.
Clear a path to the window or door and move furniture or decor at least three feet away from the opening. If the job involves an exterior door, unlocking or propping open the storm door if one is present helps. Beyond that, you don’t need to do anything; the technician arrives with the tools, the parts, and the documentation to complete the job and prove it with photos.
