Window & Door Repair Services
Before you replace it — let us fix it. Fast, professional repairs that restore performance, security, and peace of mind without the cost of full replacement.
Your windows and doors work hard every day. When something stops working, we make it right.
Impact Shield has been servicing windows and doors in South Florida since 2003. What started as a repair and maintenance company is still at the core of what we do — and that experience shows. We know these systems inside and out, we carry the right parts, and in most cases we can complete repairs on-site in a single visit.
Not every problem requires a full replacement. A door that's hard to open, a window that won't lock, a broken pane, a worn weatherstrip — these are fixable. And fixing them correctly extends the life of your system, maintains your home's security, and saves you significant money compared to a full installation.
Here's Everything We Service
Window Not Working the Way It Should? We Fix That.
Windows are used dozens of times a day. Over time, the mechanical components wear out, seals fail, and hardware breaks. Most of these issues are completely fixable without replacing the entire window — and we stock the most common parts so we can handle repairs on the spot.
Window won't stay up, is hard to lift, or slams shut.
ServiceBalance Replacement
The balance is the internal mechanism that holds a single-hung or double-hung window open and controls how it slides up and down.
When balances wear out or break, the window becomes difficult to operate — it may feel heavy, refuse to stay open, or drop suddenly.
We replace balances with the correct type and tension for your specific window model, restoring smooth, controlled operation.
Window won't lock or latch properly.
ServiceLock Repair & Replacement
A window that doesn't lock is a security vulnerability, plain and simple.
Lock mechanisms wear, corrode, or break over time — especially in South Florida's salt-air environment.
We repair or replace window locks with matched hardware, ensuring your window closes securely and latches properly every time.
Wind or water coming in around the window.
ServiceWeatherstrip Replacement & Perimeter Resealing
If you're feeling drafts, hearing wind, or noticing water intrusion around your window frame, the weatherstripping or perimeter sealant has likely deteriorated.
Weatherstrips compress and crack over time, and sealant around the frame and anchor screws can shrink, crack, or pull away from the wall.
We replace worn weatherstrip components and reseal the full perimeter — including anchor screw points — to restore a proper weatherproof barrier.
Cracked or broken glass.
ServiceGlass Replacement
We replace broken glass on-site in most cases, without needing to remove the entire window frame.
We carry a range of glass types to match your existing window's original specifications — including clear, tinted, low-E, laminated impact, and decorative options in multiple colors and finishes.
Getting the right glass matters: using the wrong type can void your window's certification, affect its energy performance, or simply look wrong.
Sliding Glass Door Problems? There's Usually a Simple Fix.
Sliding glass doors take more punishment than almost any other opening in the home — they're opened and closed hundreds of times a month, exposed to the elements, and carry significant weight. The good news is that most problems come down to a handful of components that we can replace quickly and correctly.
Door is hard to slide, feels heavy, or drags.
ServiceRoller Replacement
Rollers are the wheels that sit at the bottom of your sliding door panel and allow it to glide along the track.
Over time they flatten, crack, corrode, or seize — and when they fail, the door becomes difficult or impossible to move smoothly.
Not all rollers are the same: the correct roller depends on the door's brand, weight, frame material, and track configuration.
Using the wrong roller leads to premature failure, track damage, or a door that still doesn't operate correctly.
We identify the right roller for your specific system and replace it properly.
Door gets stuck, jumps, or derails.
ServiceTrack Cover Installation
The track your sliding door runs on takes constant exposure to dirt, debris, moisture, and foot traffic.
When the track is damaged, bent, or worn, the door can stick, skip, or jump off entirely.
In many cases, a track cover — a precisely fitted overlay installed over the existing track — solves the problem without requiring full track replacement.
Different track cover types suit different conditions: some address surface damage, others add height to restore proper roller engagement, and others provide a smooth surface when the original track has grooved or corroded.
We assess your specific situation and recommend the right solution.
Door doesn't lock securely, or you want more security.
ServiceLock Replacement, Lock Enhancers & Additional Lock Options
A sliding glass door is one of the most common points of entry for break-ins — and a worn or flimsy lock dramatically increases that risk.
We replace faulty or outdated lock mechanisms with high-quality matched hardware.
We also offer lock enhancers and supplemental locking options — including foot locks, security bars, and secondary bolt systems — for homeowners who want an additional layer of protection beyond the primary latch.
This is a simple, affordable upgrade that meaningfully improves your home's security.
Cracked or broken glass panel.
ServiceGlass Replacement
We replace broken sliding door glass panels on-site in most cases.
We carry a range of glass options to match your door's original specifications — including clear, tinted, low-E, laminated impact, and various color options.
As with windows, using the correct glass type is important: mismatched glass can compromise the door's structural performance, energy rating, or impact certification.
The Glass Doesn't Have to Change. Just What It Does.
Window film is one of the most cost-effective upgrades available for existing windows and glass doors. Professionally installed film transforms the performance of your current glass — improving energy efficiency, blocking UV radiation, reducing glare, and in the case of safety and security film, significantly reinforcing the glass against breakage and forced entry.
Architectural Film
Headline: Comfort, efficiency, and privacy — without replacing your windows.
Architectural film is designed to improve the day-to-day livability of your space.
It works by filtering the solar energy that passes through your glass, reducing the heat that enters your home or building without significantly affecting natural light.
- Heat reduction: Blocks a significant portion of solar heat before it enters, reducing the load on your air conditioning system and lowering energy bills.
- UV protection: Blocks up to 99% of ultraviolet radiation — protecting your furniture, flooring, artwork, and fabrics from fading and sun damage.
- Glare control: Reduces uncomfortable glare on screens and surfaces without darkening your space significantly.
- Privacy options: Available in a range of tints and reflective finishes that limit visibility from outside while maintaining your outward view.
- Aesthetic enhancement: Film is available in multiple shades and finishes, and can give your property a more uniform, polished appearance from the exterior.
Architectural film is ideal for homes, apartments, condos, and commercial spaces where comfort and energy efficiency are priorities.
Safety & Security Film
Headline: Your glass, reinforced. Your space, protected.
Safety and security film is a heavy-duty polyester film bonded to the interior surface of your existing glass.
On its own, standard glass shatters into dangerous shards when broken — whether from impact, blast pressure, or forced entry.
Security film holds the glass together after breakage, dramatically reducing the risk of injury from flying glass and significantly slowing or deterring entry through the opening.
This is not the same as impact-rated glass — but it is a meaningful and cost-effective layer of protection for spaces where full impact glass replacement isn't feasible or isn't the priority.
- Safe Rooms: For homeowners creating a designated storm shelter or safe room, security film on interior windows and glass doors adds a critical layer of protection — keeping glass intact under pressure and preventing dangerous fragmentation inside the room.
- Exposed Entry Points: Ground-floor windows, sidelights next to entry doors, and sliding glass doors are the most common targets for forced entry. Security film on these openings makes smash-and-grab entry significantly harder and slower — often enough to deter an intruder entirely.
- Schools: School safety protocols increasingly include glass protection as part of threat response planning. Security film on classroom windows and entry glass slows forced entry, buys critical response time, and reduces glass-related injuries in the event of an incident.
- Retail & Commercial Stores: Storefront glass is a primary vulnerability for smash-and-grab theft. Security film keeps the glass in place after impact, making rapid entry through the glass extremely difficult and costly for would-be intruders.
- Museums & Galleries: Protects high-value collections from both opportunistic theft and accidental glass damage. Also provides UV protection that preserves artwork and artifacts from light degradation.
Fresh Air In. Everything Else Out.
Screens are simple, but they matter — especially in South Florida, where open windows and doors are part of daily life for much of the year. A missing, torn, or ill-fitting screen means insects, debris, and whatever else is outside comes right in with the breeze. We measure, fabricate, and install replacement screens for all standard opening types, matched to your existing frames and hardware.
New Window Screens
Whether your screens are torn, missing, or were never there to begin with, we measure each opening individually and fabricate screens to fit.
We offer standard fiberglass mesh as well as heavier-duty options for high-traffic windows or areas with specific needs (pet-resistant, solar screen, no-see-um mesh).
Every screen is built to fit snugly in your existing frame track — no gaps, no rattling, no falling out.
New Sliding Screen Doors
A sliding screen door that doesn't glide smoothly, falls off its track, or doesn't close fully defeats the purpose entirely.
We install properly fitted replacement sliding screen doors matched to your existing door frame and track system.
We also address any track or roller issues that would prevent the new screen door from operating correctly.
New Hinged Entry Screen Doors
For front entries, side doors, and any opening with a swing door, we install hinged screen doors that close firmly, latch securely, and hold up to daily use.
Available in standard and heavy-duty configurations, with a range of frame finishes to complement your existing door hardware.
