Trusted Window Replacement for West Palm Beach Homeowners
Window Replacement cost guide: in West Palm Beach you’ll typically pay $650 to $2,400 per opening depending on frame type, glazing specification, and whether the install is a full-frame or insert replacement. Most residential jobs we handle in West Palm Beach, from the El Cid historic district to newer construction off Okeechobee Boulevard, are completed in one to two days with the written price fixed before any work begins. Call (561) 354-3861 to schedule your measured survey - the document that becomes your quote.
Since 2012, Sightline Windows & Doors has replaced more than 18,000 windows and doors under the Haven Standard, every one with a written price before a tool was lifted and a documented photo record when the job finished. West Palm Beach presents specific challenges that templated installers miss: the salt air off the Intracoastal accelerates frame corrosion on non-impact units, the summer humidity cycle swells wood sashes in older homes near Flamingo Park, and the 170-mph wind zone requirement means any replacement near the water must carry the right HVHZ certification. We specify products from eight manufacturer lines - PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux - matched to the opening’s exposure, code requirement, and your budget, not to what happens to be in a warehouse.
Our technicians are background-checked, uniformed, and identified by license number before arrival, per Haven Clause 3. The person at your door is the person on the record.
What Our Window Replacement Service Includes
Full Frame Replacement
Full frame replacement removes the entire existing window - sash, frame, and often the exterior trim - down to the rough opening. You need this when the frame itself has failed: rot in wood units, corrosion in older aluminum, or structural sag that has thrown the sightline out of square. In West Palm Beach, we see this most often in pre-1990 homes near the waterfront where salt exposure has compromised the frame integrity, and in properties where previous insert replacements were layered over already-damaged frames. Our crew performs a full diagnostic of the rough opening, measures for level and plumb to 1/16 inch, and installs a new frame system with integrated flashing that ties into your existing weather barrier. The measured survey you keep documents every frame reading.

Insert Window Replacement
Insert replacement, sometimes called pocket installation, fits a new window unit inside the existing frame and retains the original exterior trim. This works when the frame is structurally sound and you are satisfied with the current window size and sightline. It is the right choice for many West Palm Beach Window Replacement projects, especially homes built between 1995 and 2010 with aluminum frames that are weather-tight but thermally inefficient. We see this frequently in neighborhoods like Villages of Palm Beach Lakes and the newer sections of The Acreage where the frames are good but the single-pane or early low-E glass no longer meets code or comfort standards. The insert is measured to fit precisely within the existing jamb, sealed with backer rod and low-expansion foam, and finished with interior trim matched to your specification. Because the exterior trim stays intact, the job typically completes in a single day.

Vinyl Replacement Windows
Vinyl replacement windows use PVC frames with internal chambers for thermal break and structural rigidity. They are specified when the priority is thermal performance at a moderate price point and when the aesthetic of painted wood or clad aluminum is not required. In West Palm Beach, vinyl performs well inland - in Window Replacement in Greenacres, Royal Palm Beach, and Wellington - where salt exposure is less severe than the barrier island properties. We specify vinyl units from CWS and ECO Window Systems with multi-chamber frames and welded corners, not mechanically fastened sashes that can separate under expansion stress. The U-factor and SHGC are documented on the measured survey so you can compare against your utility goals. Vinyl does not corrode, does not require painting, and carries a lower life-cycle cost than wood in most Florida applications.

Energy-Efficient Upgrade
An energy-efficient upgrade replaces existing windows with units engineered to reduce solar heat gain and thermal transfer, measured by U-factor (insulation value) and SHGC (solar heat gain coefficient). In West Palm Beach, where cooling loads dominate annual energy use, the right glazing specification can reduce HVAC runtime significantly. We specify double-pane units with low-E coatings and argon fill as the baseline, and triple-pane or suspended-film systems for west-facing walls that take the afternoon sun. ES Windows manufactures a line specifically for the Florida market with SHGC values below 0.25 that we have installed extensively in Lake Worth and Palm Springs. The upgrade includes a blower-door-informed assessment where air leakage at the frame is documented, not guessed. Your written quote itemizes the performance specification of each opening so there is no substitution after contract.

Window Maintenance & Care
Window maintenance and care extends service life and identifies replacement candidates before they fail catastrophically. We perform hardware adjustment, weatherstrip replacement, sealant renewal, and operability testing on units that do not yet require full replacement. In West Palm Beach, the maintenance cycle is typically annual for coastal properties and biennial inland, driven by the salt accumulation on hardware and the UV degradation of seals. During a maintenance visit, we document frame condition with photos, measure sash squareness, and test operation force. If a unit is approaching failure, we note it in the report with a replacement recommendation and a written price for the work. This is not a sales visit; the documentation is yours whether or not you proceed.

Brands We Service for Window Replacement

We install and service eight manufacturer lines, specified by what the opening requires, not by what is in stock. Our relationship with CWS dates to 2014; we have installed their vinyl and aluminum systems in more than 2,000 West Palm Beach-area openings and maintain current certification on their impact and non-impact product families. ES Windows, a Florida-based manufacturer, produces impact-rated units with some of the lowest U-factors available for the HVHZ zone; we have specified their products for waterfront properties from Palm Beach to North Palm Beach where the 170-mph rating is mandatory. ECO Window Systems supplies vinyl frames with welded multi-chamber construction that we have found particularly durable in the humidity cycle of inland Palm Beach County. Mr-Glass manufactures custom and geometric configurations - radius tops, octagonals, and trapezoids - that we have installed in historic renovations near El Cid and in custom homes in Wellington.
Whether you have PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, or ViewLux units, or any other manufacturer, we can assess the condition, specify the replacement, and perform the installation under the Haven Standard. Our measured survey identifies the existing product line and documents any discontinuation or parts availability issue before you commit to the job.

AfterSigns You Need Window Replacement Right Now
- Visible frame damage or rot. Soft spots in wood frames, powdering aluminum, or vinyl that has cracked at the weld indicate structural failure. In West Palm Beach’s climate, frame damage accelerates once it starts - a small soft spot in a wood sash near the Intracoastal can progress to full jamb failure within two hurricane seasons because the moisture cycle never fully dries the wood.
- Condensation between glass panes. Fogging inside a double-pane unit means the edge seal has failed and the argon fill has escaped. The window is no longer insulating as designed, and in Florida’s cooling-dominated climate, you are paying to dehumidify air that the failed unit is reheating. We see this most often in units installed between 2005 and 2015 with early-generation warm-edge spacers.
- Difficulty opening, closing, or locking. Sash operation should require no more than five pounds of force. If you are shouldering a window closed or the lock no longer engages without manipulation, the frame has likely racked out of square or the hardware has corroded. In coastal West Palm Beach, salt corrosion of locking hardware is a common failure mode that we document during surveys.
- Drafts or noticeable temperature differential near the window. A hand placed near the frame on a 75-degree day should detect no air movement. Drafts indicate failed weatherstripping, frame separation, or poor original installation. In older West Palm Beach homes with original jalousie or awning windows, the problem is often the fundamental design - single-pane glass with no thermal break - and replacement with a modern fixed or casement unit is the only permanent solution.
- Escalating energy bills with no other explanation. If your HVAC runtime has increased and the equipment has been serviced, the building envelope is the likely culprit. Windows are the most common failure point. We have documented cases in Palm Beach Gardens and Royal Palm Beach where replacement of single-pane units with low-E, argon-filled systems reduced cooling load by 18 to 22 percent, measured by utility bill comparison.
Our Window Replacement Process - Step by Step

- 1
Measured survey and documentation. Our technician arrives at the scheduled time, identified by license number, and performs a room-by-room assessment. Every opening is measured for width, height, and squareness to 1/16 inch. We document frame material, condition, existing product line if identifiable, and any structural or trim considerations. You receive a copy of this survey before we leave; it is the foundation of your written quote.
- 2
Written quote with fixed price. Within 24 hours, you receive a written scope with line-item pricing per opening, product specification including U-factor and SHGC where applicable, and a total project price. Haven Clause 1 states that this price cannot change unless you change the scope. There is no “estimate range” that widens at invoice time.
- 3
Product specification and order. Once you approve the quote, we specify the exact manufacturer, series, and options for each opening from our eight verified lines. Lead times vary by product and season; we communicate the expected delivery window in writing. For impact-rated units in the HVHZ zone, we verify that the specified product carries the required Florida Product Approval or Miami-Dade Notice of Acceptance.
- 4
Installation with photo documentation. On installation day, the crew removes the existing unit, prepares the opening, installs the new window per manufacturer specification and Florida Building Code, and seals with backer rod and low-expansion foam or the specified sealant system. Every stage is photographed: before, during, and after. These photos are included in your project file as standard evidence, not an upsell.
- 5
Final inspection and 365-Day Done Right Promise. The lead technician walks the job with you, demonstrates operation, confirms lock function, and reviews the photo record. You sign a completion certificate. The 365-Day Done Right Promise, written into the Haven Standard, takes effect: if anything is not done right, we make it right. The documented photo record and the written warranty travel together.
How Much Does Window Replacement Cost in West Palm Beach?
A typical insert replacement in West Palm Beach runs $650 to $1,200 per opening, while full-frame replacement ranges from $1,100 to $2,400 depending on frame material, glazing specification, and trim complexity. Energy-efficient upgrades with low-E/argon fill add $80 to $150 per unit over base glazing. Impact-rated units for HVHZ zones, required in many coastal West Palm Beach properties, start around $1,400 for insert and $1,900 for full-frame installation. Custom geometric shapes from Mr-Glass or other manufacturers are priced individually based on engineering and fabrication requirements.
Several factors move the price within these ranges. Frame material is the largest: vinyl costs less than aluminum, which costs less than wood or fiberglass composite. Glazing specification matters - triple-pane or suspended-film systems cost more than double-pane low-E. Installation complexity affects labor: second-story openings, stucco exterior returns, or interior plaster finishes require more time and protection than standard first-floor vinyl siding applications. In West Palm Beach, we also encounter older homes with lead paint or asbestos-containing window putty; proper remediation adds cost but is non-negotiable under EPA and OSHA requirements.
To avoid overpaying, compare written quotes line by line, not just bottom-line totals. A lower quote may substitute non-impact glass in an HVHZ zone, omit permit fees, or use mechanically fastened vinyl corners instead of welded frames. Our written quote itemizes every component; bring us a competitor’s written estimate and we will review it at no charge under our Free Second Opinion policy.
Every free estimate includes the measured survey you keep, the written scope with fixed pricing, and a product specification sheet. There is no obligation to proceed.

Frequently Asked Questions - Window Replacement in West Palm Beach

Window replacement is the removal of an existing window unit and installation of a new one, either as an insert within the existing frame or as a full-frame replacement down to the rough opening. At Sightline Windows & Doors West Palm Beach, every replacement begins with a measured survey that documents frame condition, opening squareness, and product specification; the written quote derived from that survey is fixed before work starts. Call (561) 354-3861 to schedule your survey.
Most residential window replacements in West Palm Beach are completed in one to two days per project, not per opening. A full-frame replacement of ten openings in a typical single-family home near Royal Palm Beach or Wellington takes our crew two days: one day for removal and rough opening preparation, one day for installation and finish trim. Insert replacements on sound frames often complete in a single day. Custom or geometric units may extend the timeline due to fabrication lead times. Your written quote specifies the expected duration before you approve the job.
Window replacement in West Palm Beach costs $650 to $2,400 per opening depending on whether it is an insert or full-frame installation, the frame material, and the glazing specification. Insert replacements with vinyl frames and standard low-E double-pane glass typically fall at the lower end; full-frame impact-rated aluminum units for HVHZ coastal zones fall at the upper end. Your measured survey produces a written, line-item quote with no range or estimate language. Call (561) 354-3861 for your exact price - estimates are free.
Yes. We are certified installers for CWS vinyl and aluminum systems, have specified ES Windows impact-rated units for more than 500 coastal openings, have installed ECO Window Systems vinyl frames across inland Palm Beach County, and have fabricated custom geometric configurations from Mr-Glass for historic and high-end residential projects. If your existing windows are from any of these manufacturers, we can assess condition, source replacement units or parts, and perform installation under the Haven Standard. If your windows are from another manufacturer, our survey identifies the product line and determines compatibility or replacement options.
We do not perform emergency same-day installation for planned replacements - no reputable installer can fabricate, deliver, and install a custom-specified window in hours. However, we do respond to urgent situations where a failed window creates a security or weather exposure risk. In these cases, we can perform temporary board-up or film application to secure the opening, then schedule the measured survey and permanent replacement. For storm damage or break-in situations in West Palm Beach, call (561) 354-3861; live phone coverage is available 24/7 to coordinate immediate protective measures.
Every window replacement is covered by the 365-Day Done Right Promise: if it is not done right, we make it right, written into the Haven Standard, not offered as a courtesy. Beyond our workmanship guarantee, manufacturer warranties vary by product line: CWS and ECO Window Systems typically offer lifetime limited warranties on vinyl frames, ES Windows provides 10 to 20 years on impact glass depending on series, and Mr-Glass custom configurations carry specific terms based on fabrication. We document the applicable manufacturer warranty in your written scope so you know what is covered by whom before installation begins.
Clear a path to each opening by moving furniture three feet back from the window wall, remove window treatments including brackets, and secure pets in a separate room. Our crew brings drop cloths and protection for floors and adjacent surfaces, but valuable items on nearby shelves should be moved by you. For full-frame replacements, we will discuss exterior landscaping or sprinkler protection during the measured survey if the opening requires ladder access through planted beds. We do not require you to be present for the entire installation, but a brief walkthrough at completion is standard to demonstrate operation and review the photo record. Call (561) 354-3861 to schedule your survey and receive the full preparation checklist.
