Window Repair

Repaired properly, from Wilmington rowhomes to Sussex beach houses

Windows painted shut, sashes that will not stay up, cranks that spin, locks that no longer meet. Nearly all of it is a single worn component on a frame with decades of service left in it.

What a window actually is

The window, and every part of it that can fail

Before anyone talks about replacing a window, it is worth knowing what the thing is made of and which piece has actually stopped working.

A window is not a single object. It is a frame fixed into the building, one or more sashes that hold the glass, a glazing system holding that glass into the sash, a mechanism that makes the sash move and hold position, a lock that pulls everything tight, and a weatherseal that closes the gap when it is shut. Six systems, and any one of them can fail while the other five are perfectly sound.

That distinction matters because a replacement window replaces all six, at enormous cost, to solve a fault in one. A double-hung that will not stay open has a broken cord or a failed balance. A window that rattles has a worn lock or compressed stripping. A window that will not open has paint in the joint, not a structural problem. A window that fogs has a failed glass seal and a completely sound frame.

Delaware housing spans three centuries, from colonial and Victorian stock in New Castle County through mid-century ranches in Kent to the coastal builds of Sussex. That means almost every window mechanism ever manufactured is somewhere in this state, and almost all of them are still serviceable.

Sash cords, pulleys and counterweights are not obsolete and they are not beyond repair. They are among the most straightforward window repairs there is, and in Delaware's older housing we do them constantly.

The problem

Replacement windows are the most oversold product in the trade

Whole-home replacement quotes get written because that is where the margin sits, not because fourteen windows failed at once. In reality one component gives out at a time, and the rest of the window carries on.

Delaware's climate makes the sales pitch easier. A draughty window in a coastal February feels like a broken window, and a sash swollen shut in an August that runs at ninety per cent humidity feels like a failure. Both are usually repairs measured in hours.

There is a second argument worth making in this state. A well-built original sash, properly repaired and weatherstripped, will outlast the vinyl unit sold to replace it, and it already fits an opening that a modern unit would have to be shimmed into.

Six separate systems make up a window. Replacing all six to fix one is not a repair strategy.

What we fix

What we repair on a window

Operation, hardware, seals and sashes across every residential window type.

Sash cords and weights

Parted cords replaced, pulleys freed and counterweights rebalanced so an original double-hung works as designed.

Sash balances

Block-and-tackle, spiral and constant-force balances replaced on later double-hung and single-hung windows.

Crank operators

Casement and awning cranks that spin freely, bind or have stripped. The operator is replaced as a unit.

Painted-shut and swollen sashes

Freed carefully without damaging the sash, the glazing or the surrounding trim.

Weatherstripping and seals

Hardened and compressed seals renewed, which on the coast is the difference between a comfortable room and a whistling one.

Screens and storm windows

Rescreening, frame repair and storm window adjustment so combination units actually slide again.

Delaware conditions

The problems Delaware windows have

A small state with three genuinely different sets of conditions.

Humidity that does not let up

Delaware sits in a humid subtropical belt with summer humidity regularly above eighty per cent. Wooden sashes swell, joints tighten and windows that opened easily in April bind solid by July. Add generations of paint in an older home and they stop opening entirely.

Salt air along the bay and the coast

From Lewes down through Rehoboth, Bethany and Fenwick, salt-laden air corrodes balances, crank operators, locks and the small screws holding everything together. Coastal hardware seizes rather than wearing gradually, and it needs corrosion-resistant replacements.

Three centuries of housing stock

New Castle County holds colonial and Victorian homes with original weight-and-pulley sash. Kent and Sussex add mid-century and coastal construction. Each generation used different mechanisms, and treating them all as replacement candidates is how good windows get thrown away.

Why us

Why we are the state's window repair specialists

A narrow trade, worked every day, in every county.

We do not sell replacement windows

So there is no commercial reason for us to recommend one when a repair will hold. That is not a marketing line, it is how the business is structured.

Historic sash work done properly

Cords, weights, pulleys, parting beads and putty glazing. In a state with housing this old, that skill is the whole job.

Coastal-grade hardware

Corrosion-resistant components for homes near the bay and the ocean, where standard parts do not last.

Free estimates, firm prices

No charge to look, and the number does not move once work begins.

FAQ

Window repair questions

My windows are original to an old Wilmington house. Should I replace them?

In most cases, no. Original sash in sound condition, repaired and weatherstripped, performs well and lasts far longer than a replacement unit. It also fits an opening that is almost certainly no longer square.

The window will not stay up.

On an older double-hung, a sash cord has parted or a weight has come adrift. On a newer one, the balance has failed. Both are routine repairs and neither needs a new window.

My windows are painted shut.

Extremely common in Delaware's older housing. They can be freed carefully without damaging the sash or the trim, and in most cases they go on to work normally.

We are a block from the beach and everything corrodes.

Salt air is hard on window hardware. We fit corrosion-resistant balances, operators and fasteners on coastal properties, which last considerably longer than standard components.

How much does window repair cost?

It depends entirely on what failed. Cords, hardware and rescreening sit at the low end, glass costs more. You get a firm price on site and the estimate is free.
