Window Repair & Screen Replacement Experts
Complete Sliding Doors provides professional window repair and window screen replacement services for homeowners throughout South Florida. Damaged windows and torn screens can reduce energy efficiency, allow insects inside, and make your home less comfortable.
Our technicians repair window screens, window glass, and window hardware to restore proper function and airflow. Whether your window screen is torn, the glass is cracked, or the window frame needs adjustment, we provide reliable solutions designed to extend the life of your existing windows.
With 20 years of experience repairing windows and sliding doors, our team provides honest recommendations and free estimates so homeowners can choose the best repair option for their needs.
Balance springs, sash locks and sash guides are the parts that make a window hard to open, slow to close or unable to stay up. We match the part to your window, and many repairs are finished in one visit. Round springs are special order, so those take a return trip.
Common Window Problems We Repair
Balance Spring Replacement (Window Won’t Stay Up?)
Windows experience wear and damage over time due to weather exposure and everyday use. Our technicians frequently repair:
- Torn or damaged window screens
- Cracked or fogged window glass
- Loose or sagging screen mesh
- Bent or damaged screen frames
- Windows that are difficult to open or close
- Damaged window hardware
Repairing these issues early can help prevent more expensive window replacements later.
Balance Spring Replacement
A balance spring holds the sash up so the window doesn’t drop when you let go. When it weakens, the window slams shut, sinks or won’t stay open. We carry the spring types we see most, and we check the existing spring before ordering so the new one matches.
Square Balance Springs
Used on both impact and non-impact windows. We replace them in the same way, but impact sashes are heavier, so we confirm the spring rating before we install.
Round Balance Springs (3/8″ and 5/8″)
Round springs come in two diameters. Each one has an end tip that has to match the spring housing, so the tip is the first thing we check. Two tip styles are common: cross T and crow’s feet. Round springs are special order, so we measure on the first visit and come back to install.
Ultralift Impact Balance Springs
A specialty round spring made for impact windows. These are less common, so we check the window’s make and model before we quote.
Sash Lock Replacement
Sash locks keep the window closed and locked. Worn or broken locks let the window rattle, let air through and fail to secure the window. We replace the lock and check the strike plate and sash alignment at the same time.
Sash Guide & Rattle Guide Replacement
Windows that rattle, wobble, or feel loose need new sash guides or rattle guides. These small plastic parts keep the sash aligned so it opens smoothly and stays locked in position.
We replace:
Top sash guides
Bottom sash guides
Channel guides
Rattle guides
Tilt latches
Common symptoms:
Window shakes in the frame
Gaps around the sash
Drafts or wind noise
Uneven up/down movement
Difficulty locking the window
Small parts make a big difference — replacing these guides often restores a window to like-new function.
Window Beading Replacement (Glazing Bead)
Beading (or glazing bead) keeps the glass panel securely in the frame. Florida heat makes old beading brittle, warped, or cracked.
We replace glazing bead when you have:
Loose or rattling glass
Cracked or shrunk beading
Air or water leaks
Fogged windows (when replacing the IGU)
Proper beading ensures structural stability, weather resistance, and a clean appearance.
Window Screen Repair & Replacement
One of the most common window repairs is window screen replacement. Torn or damaged screens allow insects to enter your home and reduce airflow.
Our technicians provide:
- Window screen mesh replacement
- Screen frame repair
- Screen spline replacement
- Pet-resistant screen mesh upgrades
- Full screen replacement when necessary
Replacing damaged screens helps restore proper ventilation while keeping bugs outside.
Screen types, pet-resistant mesh and what to expect are covered on our window and door screen repair page.
Window Glass Replacement
If your window glass is cracked, chipped, or fogged between panes, it may be possible to replace the glass without replacing the entire window.
Our window glass services include:
- Broken window glass replacement
- Insulated glass unit replacement
- Tempered glass replacement
- Fogged window repair
Replacing the glass can restore energy efficiency and improve the appearance of your windows.
If a pane is cracked or foggy, we can often replace just the glass while we’re there. The full details, including broken, cracked and fogged glass, are on our window and door glass replacement page.
Impact Windows vs. Non-Impact Windows
Many South Florida homeowners aren’t sure what type of windows they have — or whether they should upgrade.
Impact windows use laminated glass with a reinforced frame and glazing system. If you’re unsure whether to upgrade or repair, we’ll give you honest guidance.
Impact Windows
Impact windows are designed to withstand hurricanes and debris impact. They provide:
Better hurricane protection
Enhanced security
Noise reduction
Energy efficiency
Insurance discounts
Non-Impact Windows
Non-impact windows are more vulnerable to breakage, drafts, and storm damage.
However — they can still be repaired.We repair:
Broken springs
Sash guides
Tracks and beading
Cracked glass
Window screens
Locks and tilt mechanisms
Window Repair vs Window Replacement
In many situations, windows can be repaired rather than replaced entirely. Our technicians evaluate the condition of your window frames, glass, and hardware to determine the best solution.
Simple repairs such as replacing screens or glass can often restore full functionality while saving homeowners the cost of installing new windows.
Benefits of Professional Window Repair
Repairing damaged windows offers several benefits for homeowners:
- Improved energy efficiency
- Better airflow and ventilation
- Increased home comfort
- Protection from insects and debris
- Extended window lifespan
In many cases, repairing window components is far more affordable than full window replacement.
Window Repair Frequently Asked Questions
Why won’t my window stay open?
This almost always means the balance springs are worn or broken. These springs counterbalance the sash weight. When they fail, the window becomes heavy and slams shut.
Can you repair windows that won’t slide up or down smoothly?
Yes. Smooth operation usually requires replacing balance springs, sash guides, rattle guides, or cleaning/rebuilding the tracks.
What causes windows to rattle when it’s windy?
Loose or worn sash guides or rattle guides are the cause. Replacing them tightens the sash and eliminates drafts and noise.
Do I need to replace the entire window if the glass is cracked?
No. We can replace just the glass insert (single-pane or insulated double-pane) without replacing the full window frame.
Why is my double-pane (IGU) window foggy?
The seal between the panes has failed, allowing moisture inside. The insulated glass unit (IGU) must be replaced to restore clarity.
How do I know if I have impact windows?
Look for a metal etching or sticker showing impact, laminated, or TAS 201/202/203, as well as thicker laminated glass layers. If you are unsure, we can help identify it for free.
How long does window repair take?
Most window repairs (balance springs, guides, screens) take 30–60 minutes per window.
Glass replacement typically takes 1–2 weeks to fabricate and 30 minutes to install.
Do you build custom window screens?
Yes — we fabricate screens to match the exact size of your existing frame, including pet-resistant and sun-control mesh.
Can old, hard-to-open windows be repaired instead of replaced?
Absolutely. Most older windows only need new balance springs, new sash or rattle guides, new beading, or fresh screens. These small repairs can often make them work like new again.
Is it cheaper to repair or replace a window?
Simple repairs such as replacing screens or glass are often significantly more affordable than installing new windows.
Can fogged window glass be repaired?
Fogged windows usually indicate a failed insulated glass seal. In many cases the insulated glass unit can be replaced without replacing the entire window frame.
Can you replace a balance spring on an impact window?
Yes. Impact windows use square springs and Ultralift springs, and we check the spring rating before we install.
What are cross T and crow’s feet springs?
They are two end tip styles for round balance springs. The tip has to match the spring housing, so we check it before ordering.
Do you replace sash locks by themselves?
Yes. We replace the lock and check the strike plate and sash alignment on the same visit.
Do you fix window screens and glass too?
Yes. See our screen repair and glass replacement pages for the details.
Do I need a permit?
Spring, lock and guide replacement are usually done without a permit. Glass swaps and impact replacements can differ, so we confirm before the job.
