Why Replace Your Double Hung Windows?
1. How to Know It’s Time for New Windows
- Drafts & Leaks
Feel a cold breeze even when the sashes are closed? Water stains or peeling paint around the frame? Those are your windows begging for help. - Rot & Decay
Press on the sill or jamb—if it feels soft or spongy, the wood’s had enough. - Foggy Panes
Condensation trapped between double-pane glass means the seal has failed. Goodbye insulation. - Sticks & Stops
Struggling to lift or lower the sashes? Worn balances or warped frames can be a safety hazard—and a pain. - Spiking Energy Bills
Old windows can account for up to 30% of your heat loss. If your heating or cooling costs keep climbing, drafty windows might be the culprit.

2. Picking the Right Replacement Style
Full-Frame vs. Retrofit
- Full-Frame Replacement
You remove the entire window and frame—ideal if the existing frame is warped, rotten, or you want a completely new look. - Retrofit (Insert) Replacement
New sashes and jambs fit inside the old frame. Faster and usually less expensive—just make sure the old frame is square and solid.
Frame Materials at a Glance
- Vinyl
Budget-friendly and nearly maintenance-free. Just be aware colors are factory-set, and extreme heat can warp cheaper models. - Wood
Timeless charm and natural insulation. Expect to repaint or restain every few years to keep rot at bay. - Fiberglass
Rock-steady in any climate, paintable to match your trim, and resists swelling or shrinking. Pays off over the long haul. - Composite/Clad
Real wood inside, low-maintenance metal or vinyl cladding outside. Premium price, but you get the best of both worlds.
3. Budgeting Your Project
Expense Item | DIY Range | Pro Installation Range |
---|---|---|
Window Unit (each) | $200–$500 | $200–$500 |
Labor | Your time | $100–$300 per window |
Disposal | $20–$50 | Often included |
Trim & Finish Carpentry | $50–$150 | $75–$200 |
Total per Window | $250–$700 | $375–$1,050 |
Pro tip: Swapping out three or more windows at once often unlocks contractor discounts and streamlines permit fees.
4. Step-By-Step Replacement
- Measure Carefully
Take three measurements (top, middle, bottom) of width and height—use the smallest number to order. - Order Your Windows
Pick glass options (Low-E coatings, argon fill), grilles, and hardware. Custom jobs can take 4–6 weeks. - Prep the Opening
Pull off interior trim and sashes, then remove the old frame. Check the sill for hidden rot and repair it now. - Install the New Unit
Set it square and level, shim all four corners, secure according to the manufacturer’s guide, then wrap it in flashing tape and seal with top-quality caulk. - Finish & Protect
Reinstall or replace your trim, paint or stain as needed, and run both sashes through their paces. - Seal the Deal
Register your warranty—then sit back and enjoy smooth, draft-free windows for years to come.

6. FAQs from My Own Experience
How long does a window swap take?
A single window can be professionally replaced in 1–2 hours; a full-house project of 10–15 windows usually wraps up in 1–3 days.
Do I need a permit?
Retrofit replacements rarely need one, but full-frame swaps often do—check your local building codes before you start.
Which energy features really matter?
Look for ENERGY STAR® certification, Low-E glass, argon fills between panes, and multi-point locking hardware for top performance.
Can I keep my existing trim?
Sure—if it’s still in good shape. But many folks swap to new trim at the same time for a fresh, cohesive look.
What maintenance will new windows need?
Vinyl and fiberglass windows usually just need a wipe-down and an annual balance check. Wood frames ask for painting or staining every few years to stay happy.
