Stop wasting money on full window replacements. In most cases, a professional repair is all you need — and it costs a fraction of the price. We fix windows right the first time.
Is Your Window Driving You Crazy? You're Not Alone.
These are the most common window problems we see every day. They're frustrating — and they're all fixable without replacing your entire window.
Windows That Won't Open or Close
Stuck, jammed, or stiff windows that take two hands and all your strength to budge. A daily frustration that shouldn't exist.
Very CommonBroken Balancer Systems
Your sash crashes down the moment you let go. Or it won't stay open at all. A broken balance system makes windows dangerous and unusable.
Safety IssueFaulty or Broken Locks
A lock that doesn't catch, won't latch, or has broken completely. That's not just inconvenient — it's a security risk for your family.
Security RiskDrafts & Air Leaks
Feel a cold breeze near your window when it's closed? Failed seals and worn weatherstripping let outside air — and your heating bill — spiral out of control.
Energy LossRotten Wood Frames
Soft, spongy, or visually deteriorating wood around your window. Left untreated, rot spreads — and what's a simple repair today becomes a full replacement tomorrow.
Act FastWater Leaks & Moisture Damage
Water stains around your window frame, peeling paint, or visible moisture. Gaps in caulking and failed seals let rainwater in every storm.
Structural RiskDealing with one of these? Don't wait — small window problems become expensive ones fast.
We Fix It All — The Right Way, The First Time
From broken balancers to rotted wood, our technicians have the skills and tools to restore your windows to full function — without unnecessary replacements.
Balance System Repair
We replace broken springs, spiral balancers, and block-and-tackle systems so your windows open, hold, and close smoothly and safely.
Lock Repair & Replacement
Faulty latches, broken handles, and failed locks are repaired or replaced to restore full security to every window in your home.
Glass Repair & Replacement
Cracked, broken, or foggy single panes? We replace damaged glass units quickly and cleanly — no frame removal required.
Waterproofing & Caulking
We remove old, failing caulk and apply professional-grade sealants to stop drafts, moisture infiltration, and water damage at the source.
Wood Rot Repair & Restoration
We don't just paint over rot — we excavate the damaged wood, treat the area, and rebuild with architectural epoxy or treated timber for a permanent fix.
Hardware & Mechanism Repair
Hinges, operators, tilt latches, and all other window hardware — we source correct replacement parts and get your windows working like new.

Better Security
Locks that latch properly give you peace of mind — especially at night.
Draft-Free Comfort
Proper sealing keeps cold air out in winter and cool air in during summer.
Major Cost Savings
Repair instead of replace — often at 20–30% of full window replacement cost.
