Window Replacement & Installation in Lancaster & Central PA
If your home has drafty windows, rising energy bills, or frames that are showing their age, window replacement is one of the smartest upgrades you can make. At RFO Contracting, we serve homeowners throughout Lancaster County and Central PA with quality window installation, honest service, and attention to detail on every project.
Signs It’s Time to Replace Your Windows
Not sure if your windows actually need replacing? You’re not alone. Most homeowners put it off longer than they should, and it ends up costing more in the long run. Here are the clearest signs it’s time to take action.

Cold Drafts and Air Leaks
If you can feel cold air near a closed window, the seal has failed. That means outside air gets in year-round, making your heating and cooling systems work much harder than they should.

Energy Costs Going Higher
Older windows are a major source of energy loss in homes. If your utility bills keep creeping up and you haven’t made other changes recently, your windows are likely the culprit to address first.

Damaged or Rotting Frames
Wood frames are especially vulnerable to moisture over time. Once rot sets in, it doesn’t stop and can spread to the surrounding wall. Soft spots, peeling paint, or visible decay are all clear warning signs.

Condensation on the Glass
Foggy glass between panes means the insulated seal has broken down. That window is no longer doing its job, and wiping the glass won’t fix it. The only real solution is to replace the unit.

Difficult to Open or Lock
A window that won’t lock is a safety issue, not just an inconvenience. If your windows are warped, painted shut, or hard to operate, that’s a clear sign they’ve reached the end of their life.

Types of Replacement Windows We Install
Whether you’re replacing one problem window or upgrading your entire home, we’ll help you choose the right style for your space, your budget, and the way you live. Here are the types of windows we install:
- Casement windows
- Double-hung windows
- Sliding windows
- Custom and specialty shapes
Replacement Windows vs. New Construction Windows
This is one of the most common questions we hear, and it’s a good one.
Replacement windows are designed to fit inside your existing frame. They’re the right choice for most upgrades because the installation is less invasive, faster, and more affordable. If your frames are in good shape, replacement windows are almost always the way to go.
New construction windows include the full frame and are the better option when the existing frame is damaged, rotted, or when you’re adding a window to a wall that didn’t have one before.
During your estimate, we’ll look at your existing frames and give you an honest recommendation. There’s no upsell here. We’ll tell you what you actually need.
