AfterTrusted Window Installation Nationwide
Window installation means removing old, failing units and setting new ones so they operate smoothly, seal tightly, and look right from both inside and out. Juniper Windows & Doors has handled our Window Installation in Los Angeles and beyond since 2001 as part of the Relay Home Co. family, with background-checked, uniformed technicians on every job. We carry eight product lines – PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux – so the right window is never a compromise. Every project gets a written price before any work starts, and the 365-Day Done Right Promise covers parts and labor for a full year after installation. Call (682) 281-2168 any time – a real person answers, 24/7.
Casement Windows
Casement Windows hinge at the side and crank outward, giving you a full, unobstructed opening and one of the tightest seals of any window style when closed. Homeowners choose them for kitchens, bathrooms, and any spot where easy operation matters, because the crank mechanism beats pushing a heavy sash up and down. Juniper Windows & Doors installs casement windows from CWS and ES Windows, and a standard replacement typically runs $450 to $900 per unit depending on size and glass package. We check the crank hardware, hinge alignment, and weatherstripping on every install so the window opens with one hand and locks down air-tight.
Sealing and Hardware Checks
Casements depend on a compression seal, which means the sash has to press evenly into the frame on all four sides. Our technicians adjust the hinge tracks and lock points during installation, not after the first draft shows up. If the old casement was sticking or whistling in the wind, the new one gets set to close flush every time.
Impact-Rated Casement Options
For homes in storm-prone areas, we install impact-rated casement glass built to resist wind-borne debris without shattering. The frame reinforcement is hidden inside the window, so sightlines stay clean. We’ll show you the U-factor and structural rating on paper before you sign anything.
Double Hung Windows
Double Hung Windows have two operable sashes that slide up and down independently, so you can open the top, the bottom, or both for ventilation. They fit nearly any architectural style and are a top pick for bedrooms and living areas where you want airflow without a crank or a swinging panel. Juniper Windows & Doors installs double hungs from ViewLux and ECO Window Systems, with typical replacement pricing between $380 and $800 per window. Both sashes tilt inward for cleaning, which is a detail we walk through at the end of every job.
Tilt-In Sash Alignment
A double hung only works smoothly when both sash springs or balances are matched to the glass weight. If one side is over-sprung, the window slams or won’t stay open. We set the balance tension on site so the sashes move evenly and hold position at any height.
Draft-Free Frame Sealing
Most double hung air leaks come from the meeting rail, where the two sashes overlap in the center. Our installers add fitted weatherstripping at that junction and check the side jambs with a smoke pencil before they call the job done. The result is a window you can stand next to in winter and not feel a thing.
Vinyl Windows
Vinyl Windows are made from uPVC frames that never rot, never need painting, and resist the expansion and contraction that warps wood over time. They are the most common replacement window in the country because they deliver strong thermal performance at a price homeowners can absorb. Juniper Windows & Doors installs vinyl windows from CWS and Mr-Glass, with most replacements running $350 to $750 per unit installed. The frames are fusion-welded at the corners, which we inspect before installation so no window leaves our truck with a weak joint.
Multi-Chamber Frame Construction
The chambers inside a vinyl frame trap air and slow heat transfer better than a solid extrusion. We match the frame profile to the glass package so the whole assembly hits the efficiency target you are paying for. That U-factor on the sticker is only real if the frame and glass work together.
Low-Maintenance Frame Care
Vinyl never needs sanding, staining, or caulking touch-ups the way wood does. A quick wipe with soap and water keeps the frame looking new for years. We still check the weep holes and drainage channels on every install, because even a maintenance-free frame moves water the wrong way if those get blocked.
Picture Window
A Picture Window is a fixed, non-operable pane built to frame a view and flood a room with daylight without any rails or sashes breaking the sightline. It is the most energy-efficient window style because it never opens, so there are no leak points at all. Juniper Windows & Doors installs picture windows from ES Windows and ECO Window Systems, with a standard unit running $400 to $1,200 depending on glass area and performance coating. If the view is the point, this is the window that gets out of the way.
Glass Package Selection
The glass you pick for a picture window does more work than the frame. We walk through double-pane, triple-pane, and low-E coating options in plain language so you understand what the U-factor and solar heat gain numbers mean for your utility bill. A big south-facing picture window often calls for a different coating than a shaded north wall.
Structural Framing and Flashing
Large fixed panes put real weight and wind load on the rough opening. We check header and sill framing before the window goes in, then flash the perimeter to shed water away from the wall cavity. The last thing a picture window should do is let water behind the siding where you cannot see it.
Bay Window Installation
Bay Window Installation projects out from the wall, creating a three-dimensional alcove that adds floor space, window seat potential, and a wider view than a flat window. A bay is actually three windows joined at angles – typically a fixed center picture window with operating side units. Juniper Windows & Doors installs bays from PGT and CWS, with most full bay replacement projects landing between $2,500 and $6,500 depending on size, seat board, and roof structure. This is structural work, not a like-for-like swap, and we treat it that way from the first measurement-something we cover in detail in The Complete Window Installation Guide for Los Angeles Homeowners.
Roof, Seat, and Support Structure
A bay window has to carry its own weight plus wind and snow load, so the support structure underneath matters as much as the glass. We build the seat board and exterior roof to code, insulate the cavity, and flash the roof line so water drains off instead of pooling. Get this wrong and the window becomes a slow leak into the wall.
Tight Joint Sealing at the Angled Corners
Where the three window units meet at angles, the joinery is the weak point for air and water. Our installers seal those joints with structural mullion posts and exterior flashing, then test the bay with a moisture meter before interior trim goes back on. The bay should look like one built-in unit, not three windows bolted together.
Window Contractor
A Window Contractor is the company that measures, sources, and installs your windows – and should also stand behind the work after the truck leaves. The wrong contractor leaves you with warped sashes, fogged glass, and a quote that changes at the door. Since 2001, Juniper Windows & Doors has operated on one standard: a written price before a single screw turns, and the 365-Day Done Right Promise covering parts and labor for a full year. You will see the total cost on paper before you commit, not after the old window is on the ground.
Licensed, Insured, and Background-Checked
Every Juniper technician is background-checked and uniformed, so the person at your door is the person we said would be there. Our insurance and licensing stand behind the crew. You should never have to ask a window contractor for proof – it should be standard, and with us it is.
Written Price, No Change Orders
The price we quote is the price you pay, unless you change the scope. That is in writing. If we find rot in the rough opening after the old window comes out, we stop, show you a photo, and give you a new written price before doing one more cut. No surprises, no “we’ll figure it out later.”
Window Installers
Window Installers are the hands-on crew doing the removal, framing repair, setting, leveling, flashing, and trim work on every unit. Their skill decides whether the window operates smoothly for twenty years or sticks in year two. Juniper Windows & Doors sends trained, uniformed installers on every job, with photo updates and a digital invoice you can pay from a link. Typical installation labor runs $150 to $400 per window, already included in our total written quote.
Level, Plumb, and Square Setting
A window that is out of square by even an eighth of an inch will bind, leak, and wear out its hardware early. Our installers shim every unit to level and plumb, then check the diagonal measurements before fastening. The sash test comes right after – open, close, lock, unlock, repeat until it moves like furniture, not machinery.
Cleanup and Disposal Included
Removing old windows creates broken glass, rotted wood, and a pile of packing material. We haul it all away as part of the job and leave the work area swept. You will not find a single shim or strip of flashing left behind on the floor or in the yard.
Brands We Service
We install and service CWS windows regularly, including their impact-rated and energy-efficient vinyl lines. Our installers know the frame profiles, hardware, and balance systems on CWS units, which means faster, tighter installation and smoother operation from day one.
ES Windows and ECO Window Systems are also in our regular rotation, particularly for homeowners who want strong thermal performance without stepping up to a luxury price point. And Mr-Glass rounds out the lineup with dependable vinyl and aluminum options that fit tighter budgets. Whether you have one of these brands or any other make, we can help – call (682) 281-2168 and we will tell you straight what it takes.
Signs You Need a Pro Right Now
- Condensation between the glass panes. This means the seal has failed and the insulating gas has leaked out. The window will never perform again until the glass unit is replaced; no cleaning or caulking fixes it.
- Drafts you can feel standing six inches away. Air coming through a closed window means failed weatherstripping, a warped sash, or a bad frame seal. Your heating and cooling are escaping around the window, which shows up on the bill every month.
- Windows that stick, slam, or will not stay open. A double hung that drops on its own has a failed balance. A casement that grinds has worn crank gears. Forcing them risks breaking the glass or the frame, and both cost more than a repair visit.
- Visible rot, mold, or soft wood around the frame. Water is getting into the wall cavity, and by the time the trim looks bad, the framing behind it is usually worse. A pro needs to open that wall and see how far it goes before the window gets replaced.
- Street noise that seems louder than it used to. Aging single-pane or failed double-pane windows let in far more sound than modern insulated glass. New installation with laminated or thicker glass can cut that intrusion dramatically.

How Much Does Window Installation Cost?
Window installation prices vary by window type, size, frame material, and the condition of the rough opening. A basic vinyl double hung runs $350 to $750 per unit installed. Casement windows land between $450 and $900. A picture window typically costs $400 to $1,200 depending on glass area and coating. Bay window projects start around $2,500 and can reach $6,500 when you factor in the roof, seat board, and structural support. Labor alone averages $150 to $400 per window, already bundled into our written quote.
The three biggest price drivers are the glass package (double versus triple pane, low-E coatings, impact rating), the frame material (vinyl costs less than wood or aluminum-clad options), and what we find when the old window comes out. Rot or water damage behind the frame adds carpentry time and material. To avoid overpaying, get a written line-item quote that separates windows, labor, and disposal – every Juniper quote does. Our free estimate includes exact measurements, a fixed price, and a full explanation of what the job entails. Call (682) 281-2168 and you will know the number before we leave your driveway.

Frequently Asked Questions About Window Installation
Window installation is the process of removing an old or failed window and setting a new unit into the opening so it is level, plumb, sealed, and fully operational. It includes flashing the perimeter, insulating the gaps, and often replacing rotted framing around the opening. Juniper has done this work since 2001, with written pricing before any work starts.
Most single-window replacements take one to three hours from removal to final cleanup. A full home of ten to fifteen windows usually takes one to two days depending on framing condition and access. Bay and structural projects run longer, and we will give you a realistic timeline in your written quote.
You should budget $350 to $750 per vinyl double hung installed, $450 to $900 for casements, and $400 to $1,200 for picture windows. Bay windows start around $2,500 and run to $6,500 with roof and structure work. Call (682) 281-2168 for an exact line-item quote – the estimate is free and the price is locked in writing.
