We’re the windows-and-doors specialist inside the Relay Home Co. family. That means no general remodeling, no unrelated trades, just one job done well. Our home base of operations covers the full spectrum of replacement work, from a single failed pane to a full-house upgrade.

Energy Efficient Windows

Energy Efficient Windows are replacements designed to reduce heat transfer through the glass and frame, measured by U-factor and Solar Heat Gain Coefficient. You need them when your current windows are letting conditioned air escape in summer and cold air seep in during winter, which shows up as higher utility bills and rooms that never feel comfortable. Juniper Windows & Doors installs energy efficient windows from product lines like ECO Window Systems and Mr-Glass, with a typical full-home replacement running $650 to $1,150 per window depending on glass package and frame material. The written price you get before work starts includes the specific glass performance ratings, so you know exactly what you’re paying for.

Low-E Glass Options

Low-emissivity coatings are microscopic metallic layers that reflect heat back toward its source while letting light pass through. We walk through which coating works for your orientation: south-facing windows benefit from a higher solar heat gain in cold months, while west-facing glass needs a lower coefficient to block afternoon sun. The difference in glass cost is usually $40 to $80 per window, and it pays for itself within a few years.

Whole-Home Energy Audits

Before recommending any window package, we check the entire envelope: existing insulation depth, air leakage around frames, and how your HVAC system is performing. A single-wall house with poor attic insulation gains more from moderate double-pane glass than from premium triple-pane units. That honest assessment is how we avoid selling you more window than your home actually needs.

Window Repair

Window Repair is the process of fixing what’s broken on an existing window, from a failed balance and a cracked pane to worn weatherstripping and rotted frame sections, without replacing the entire unit. You need repair when the window won’t stay open, lets in air around the edges, or shows condensation between the glass. Juniper Windows & Doors handles repair calls with the same written-price standard as full replacements, with most window repair jobs running $125 to $310 per window. We stock hardware and weatherstripping for the product lines we install, which speeds up the fix considerably.

Balances and Springs

A window that slams shut when you let go has a failed balance system. We carry replacement balances for double-hung and single-hung windows, and the repair usually takes under an hour per window. You’ll get a written price that covers parts and labor before we open the wall, not after.

Hardware and Weatherstripping

Cranks, locks, and sliding tracks wear out over time, especially in high-use windows like the one over the kitchen sink. We replace worn hardware and compression weatherstripping in a single visit, which goes a long way toward stopping drafts without changing the glass. The 365-Day Done Right Promise covers this work in writing.

Window Replacement Company

A Window Replacement Company is a specialist that removes old windows and installs new ones in the same openings, handling everything from measurement and ordering to final trim and cleanup. If you’re in Southern California, learn more about our Los Angeles Window Replacement services. You need one when repairs stop making sense: multiple failed seals, frames that are soft to the touch, or windows that are simply past their service life. Juniper Windows & Doors has focused exclusively on windows and doors since 2001, and full window replacement through us typically runs $550 to $950 per opening for a standard double-pane vinyl window, including installation. Lead times for custom orders from our product lines run two to six weeks depending on the manufacturer.

What Separates Us From General Contractors

A general contractor splits attention across kitchens, bathrooms, and roofs. We install windows every working day, so we catch issues before they become callbacks: a slightly out-of-square rough opening, a hidden rot pocket, or a misordered sash size. That focus is why we can stand behind the 365-Day Done Right Promise without hesitation.

Multi-Window Project Coordination

Replacing twelve windows across two floors requires sequencing that keeps the house livable while the work is happening. We schedule in zones, seal each opening as it’s completed, and finish one floor fully before starting the next. You’ll see photo updates of the progress without having to leave your desk.

Window Glass Replacement

Window Glass Replacement is the process of replacing only the glass unit inside an existing frame, rather than tearing out and replacing the entire window assembly. You need it when the glass is cracked, shattered, or fogged between the panes but the frame itself is still square and solid. Juniper Windows & Doors performs insulated glass unit replacement for most double-pane windows, with typical costs running $200 to $450 per pane depending on dimensions, glass type, and whether the unit has argon fill or low-E coating. The frame stays in place, which keeps the job fast and protects your interior trim.

Insulated Glass Unit Replacement

Most modern windows are built around a sealed unit: two panes of glass separated by a spacer and sealed with an inert gas fill. When the seal fails, the gas escapes and you get that permanent fog between the panes. Replacing the unit restores the window’s thermal performance to factory spec, and we order the replacement to the exact same dimensions plus the right spacer width for the frame.

What to Expect During a Glass-Only Job

Glass replacement usually takes under an hour per window once the replacement unit arrives. We remove the old glazing, clean the reglet, set the new unit on fresh setting blocks, and redo the interior and exterior bead. Your written price includes the measurement, the custom glass order, and the installation, with no added trip charge hiding in the fine print.

Window Sash Replacement

Window Sash Replacement is the process of replacing the moving part of the window, the framed panel that holds the glass, while the outer frame stays fixed in the wall. You need it when the sash itself has structural problems: rotted wood at the meeting rail, a cracked frame corner, or a fogged glass unit in an otherwise sound opening. Juniper Windows & Doors offers sash replacement as a middle option between repair and full tear-out, with costs typically landing between $325 and $650 per sash depending on material and glass package. It’s a strong choice when the window frame is plumb, level, and still well-sealed at the rough opening.

Wood Sash Restoration vs. Replacement

Older homes often have solid wood sashes that are worth saving, while newer builder-grade sashes are not. We’ll tell you honestly which one you have: if the wood is sound and the joinery intact, a repair and reglaze makes more sense than a new sash. If the corner joints are separating, a replacement sash with the same exterior profile keeps the look without the recurring rot.

When a Sash Replacement Makes Financial Sense

A failed glass seal in an upper-story window that otherwise operates fine is a textbook sash replacement job. You keep the frame, the trim, and the exterior cladding, and you pay roughly half of what a full window replacement would cost. That math only works if the frame is solid, which is why we inspect the sill and jambs before recommending this route.

Window Glass Repair

Window Glass Repair is the targeted fix for glass that is cracked, scratched, or punctured but still in place, as opposed to a full pane or unit replacement. You need it when a lawn mower kicks up a rock, a branch hits the window, or a stress crack appears without any obvious cause. Juniper Windows & Doors evaluates each break first: we check whether the crack has reached the frame edge, whether the window is tempered or annealed, and whether the break compromises the structural integrity of the unit. Minor glass repair jobs run $125 to $300, while a full insulated unit runs higher and is priced in writing before we order it.

Stress Crack Diagnosis

A crack that starts at the edge and runs inward is usually a stress fracture from frame movement, improper installation, or thermal expansion. That’s a sign the glass was over-constrained when it was set, and patching the crack won’t stop the underlying pressure. We look for the cause before the fix, so a repair doesn’t become a repeat visit.

Safety Film as a Temporary Measure

If a replacement can’t be installed the same day, a clear safety film can hold fractured glass in place and reduce the risk of falling shards until the new glass arrives. It’s a stopgap, not a permanent fix. We’ll include it in the written price when it’s needed, and schedule the permanent repair with a firm date, not a vague window.

Window Pane Replacement

Window Pane Replacement is the job of removing a single damaged pane of glass and installing a new one, most often in older single-pane windows or in situations where one pane of a double-glazed unit is broken. You need it when you can see a clear break in a single pane and the rest of the window operates normally. Juniper Windows & Doors handles single-pane replacements for older homes and select multi-pane configurations, with typical single-pane replacement running $150 to $375 including the replacement glass, glazing, and interior cleanup. The price depends on square footage, glass thickness, and whether the pane is standard annealed, tempered, or laminated.

Single-Pane vs. Double-Pane Considerations

A single-pane window is inherently less efficient than even an entry-level double-pane unit. When a single pane breaks, we’ll tell you what a pane replacement costs and what a full upgrade to an insulated unit costs, then let you make the call. No pressure, just the numbers in writing.

Glass Types We Install

We carry and order standard annealed glass, tempered safety glass for doors and low windows, and laminated glass for impact resistance. Tempered glass shatters into small cubes rather than sharp shards, which matters where a pane is near a door or in a wall adjacent to a stairway. Your written estimate will specify the glass type the replacement requires.

Window Seal Repair

Window Seal Repair is the process of restoring the airtight barrier between the glass panes and the surrounding frame, which keeps out moisture, air, and noise. You need it when you see condensation between the panes, feel a draft around the window edges, or see water staining near the sill. Juniper Windows & Doors addresses seal failures by replacing the failed insulated glass unit, repairing or replacing glazing tape, and re-sealing the perimeter with backer rod and a high-grade sealant. Basic seal repair around the window perimeter runs $100 to $250, while a failed seal inside an insulated glass unit means glass replacement and runs $200 to $450 per unit.

Exterior Perimeter Sealing

A gap between the window frame and the exterior siding lets in more air and water than most homeowners realize. We cut out the old, dried-up sealant, install fresh backer rod where the gap is deep, and lay a continuous bead that can handle the seasonal expansion and contraction of the wall assembly. The difference in a drafty room is often immediate.

Insulated Unit Seal Failure

Condensation between the panes means the internal seal has allowed the inert gas to escape and moisture to enter. No surface coating or defogging service fixes this permanently. We replace the sealed unit with new glass, new spacer, and fresh argon fill where the window calls for it, restoring the thermal break to original spec.

Brands We Service

We work with eight product lines: PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux. That range exists for a reason: no single manufacturer makes the right window for every opening, every climate, and every budget. CWS has a strong line of impact-rated windows and doors that hold up in coastal wind zones. ES Windows is known for precise aluminum framing and clean sightlines, and ECO Window Systems builds an excellent value-focused vinyl window that we recommend often for full-home replacements.

Mr-Glass supplies a solid range of entry-level and mid-grade insulated units that make glass-only replacement practical for many homeowners. Whether you have CWS, ES Windows, ECO Window Systems, Mr-Glass, or any other make, we can help. If a product line from our list won’t serve your house’s needs, we’ll tell you that directly and point you to the one that will.

Signs You Need a Pro Right Now

• Fog between the panes. When condensation won’t wipe off and sits between the two layers of glass, the internal seal has failed and the window has lost most of its thermal performance. The fix is a sealed unit replacement, not a wait-and-see.
• A window that won’t stay open. A failed balance or a broken sash cord means the window can slam shut without warning. That’s a finger injury waiting to happen, especially in a house with kids.
• Visible daylight around the sash. If you can see light streaming around the edges of a closed window, air and water are following that same path. The longer that gap stays open, the higher the chance of rot in the surrounding framing.
• Rotted or soft wood at the sill. Push a screwdriver tip into the sill where it meets the siding. If it sinks, the wood is compromised and needs addressing before it spreads into the wall structure.
• Windows that won’t lock. A lock that no longer aligns is a security gap as much as a mechanical problem. It also signals that the sash has warped or shifted, which means the window isn’t sealing properly.

Our Process, Step by Step

1. 1
   Book in a tap. You call (682) 281-2168 or book online, and you get a live arrival time you can track, no four-hour windows and no phone tag. The appointment is scheduled around your day, not the other way around.
2. 2
   Measure and assess. A background-checked, uniformed technician inspects every opening, checks for hidden rot, verifies square and level, and takes precise measurements in three places per dimension. This is where the written price starts to take shape.
3. 3
   Written price, before any work. You get a line-item price in writing that covers every opening, every product, and every bit of labor. That number does not change at the door. No re-quotes, no “we found something” upcharges, no surprises.
4. 4
   Installation day. The crew arrives at the scheduled time, protects the work area, removes the old windows, sets the new ones, insulates and seals every opening, and cleans up thoroughly. You’ll get before-and-after photos of every opening.
5. 5
   Final walkthrough and digital invoice. We walk the job with you, answer any questions, and send the invoice as a link you can pay from your phone. Your 365-Day Done Right Promise starts that day, in writing.
