Door & window repair, statewide
Delaware Doors & Windows
Door and window repair in every city in Delaware
Sliding doors that will not slide, sashes painted shut, fogged glass, rotted thresholds and locks that no longer meet — repaired on site, usually in a single visit and almost always for far less than replacement.
The repair specialists Delaware homeowners call first
We do one thing: repair the doors and windows in Delaware homes. Not sell replacements, not fit new units, not quote you for a whole elevation when one component has failed. Repair.
That matters more here than in most states, because Delaware packs an unusual amount of variety into nine hundred square miles. Colonial and Victorian housing in New Castle County with original weight-and-pulley sash. Mid-century and agricultural building through Kent. And a coastal belt in Sussex where salt air, beach sand and seasonal rentals wear hardware out at a rate inland homes never see. A company that only knows one of those is going to get the other two wrong.
We work all three counties, we give you a firm price before we start, and the repair happens at your property.
Most of it has been getting worse for years
Doors and windows rarely fail suddenly. Salt gets into a roller bearing, another coat of paint goes over a sash lock that already did not close, a humid August swells every wooden door in the house, water sits at a threshold that stopped draining. None of it announces itself.
Then one day the patio door needs two hands, and the quote that arrives is for a new door. We would rather fix what actually failed and tell you honestly which situation you are in.
- A patio door that drags, grinds or takes both hands
- A window painted shut that has not opened in years
- Haze or moisture trapped between two panes of glass
- A sash that will not stay up when you let go
- A deadbolt you have to lift the door to turn
- Soft or darkened wood at the bottom of a door frame
- A door that binds in August and gaps in January
- Hardware near the water that has corroded solid
Doors and windows, start to finish
Delaware Doors & Windows handles the whole opening — the panel or sash, the frame around it and the hardware that moves it.
Sliding glass door repair
Rollers, tracks, glass panels, locks and alignment on the door most Delaware homes use daily.
Patio door repair
Sliding, French, hinged and folding patio doors realigned, resealed and re-rollered.
Window repair
Sash cords and weights, balances, cranks, painted-shut sashes and weatherstripping.
Window glass repair
Cracked panes, fogged sealed units and failed putty, reglazed in the sash you already have.
Door repair
Entry, interior and closet doors that stick, sag, drag or will not close cleanly.
Door lock repair
Deadbolts that bind, latches that miss the strike, and security on the openings that matter.
Window lock repair
Sash locks, keepers and casement hardware, including locks painted solid decades ago.
Weatherstripping and seals
Hardened seals renewed on doors and windows, which on an exposed coastal elevation is immediately noticeable.
Screens and rescreening
New mesh, rebuilt frames and custom sizes for older openings.
Every repair we offer, in one place
Doors and windows are the entire business. Nothing below is a sideline to something else.
Some of it is what people expect: a patio slider that will not move, a cracked pane, a window that will not stay open. The rest tends to surprise people — a sash lock painted solid decades ago, a parted cord on an original double-hung, a strike plate that has been out of line since the last humid summer.
Pick the service that matches your problem and you will find how we approach it. If you are not sure which one you need, call and describe what it is doing — working that out is part of the job.
Not sure where your problem fits? Call (302) 406-0168 and we will tell you.
A small state with three different sets of problems
Ninety-six miles top to bottom, and the way a door fails in Wilmington has almost nothing in common with how it fails in Bethany.
Salt air along the bay and the coast
From Lewes through Rehoboth, Bethany and Fenwick, salt corrodes roller bearings, lock cylinders, balances and the small screws holding everything together. Coastal hardware seizes rather than wearing gradually, and it needs corrosion-resistant replacements to last.
Beach sand in the tracks
In Sussex, sand comes home on feet, towels and dogs and goes straight into sliding door tracks. Mixed with old lubricant it becomes a grinding paste, and it is the fastest way there is to destroy a set of rollers.
Humidity that swells everything
Delaware summers run hot and genuinely humid. Wooden doors and sashes take on moisture, bind solid by July and then shrink back through a heated January. The same opening sticks in one season and rattles in the other.
The lowest-lying state in the country
A great deal of Delaware housing sits close to grade with a high water table beneath it. Water that cannot drain away from a threshold or a sill goes into the framing instead, and wood-framed construction does not tolerate that for long.
Three centuries of building
New Castle County holds colonial, Federal and Victorian homes whose openings have been settling for two hundred years. Original sash, mortise locks and out-of-square frames are everywhere, and they need repairing rather than ripping out.
Nor'easters and coastal storms
Winter nor'easters and the remnants of tropical systems both reach Delaware, driving rain horizontally at exactly the openings least able to shed it. Hardened seals and blocked sill drainage are what turn that weather into water damage.
Three steps, no runaround
Tell us what it is doing
Call or text. Photos help enormously, and you can send them straight over.
We diagnose on site
A technician checks the panel or sash, the frame and the hardware, then quotes a firm price before any work begins.
We repair it
Most repairs are finished the same visit. Glass is cut to size, so that follows on a short return trip.
Why we are the state's door and window specialists
We do not sell replacements
No replacement doors, no replacement windows. There is no commercial reason for us to recommend one when a repair will hold.
Doors and windows only
Not a general handyman service that occasionally touches them. It is a narrow trade and we work it every day.
Coastal-grade hardware
Corrosion-resistant components on properties near the water, where standard parts do not survive a season.
Old houses handled properly
Sash cords, mortise locks and openings that have not been square since the 1800s are routine work here.
Straight pricing
You get the number before we start. It does not move once we are working.
All three counties
Wilmington to Fenwick Island, and every town in between. Nowhere in Delaware is out of the way.
Serving every city in Delaware
We are a mobile service covering New Castle, Kent and Sussex. Wherever you are, we come to you.

Questions we get every week
My sliding door is really hard to open. What is wrong?
Almost always the rollers underneath have worn flat or seized, so the panel drags instead of rolling. Near the coast, salt corrosion is usually behind it; inland it is more often sand and grit in the track. Either way it is a repair, not a replacement.
My windows fogged up between the panes. Can that be fixed?
Yes. The sealed glass unit has failed and moisture has got in. We replace the unit inside your existing sash — the window itself stays exactly where it is.
My house is old and the windows are original. 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.
Everything on my beach house corrodes. Is there anything better?
Yes. Sealed stainless-bearing rollers and corrosion-resistant hardware last considerably longer in coastal conditions than the standard components most doors and windows ship with, and they are worth specifying.
My doors stick in summer and gap in winter.
That is wood responding to Delaware's humidity swing. The right fix is adjusting hinges and strikes rather than planing material off, because a door planed in August leaves a gap in January.
How much does a repair cost?
It depends on what failed. Rollers, hardware and rescreening sit at the low end; glass, rot and track work cost more. You get a firm price on site before we start, and the estimate is free.
Do you work with landlords and rental properties?
Yes, across all three counties, including the seasonal rental stock in the coastal towns. Doing several repairs in one visit is considerably cheaper than one at a time.
Do you serve my town?
We serve all of Delaware — New Castle, Kent and Sussex counties, from Wilmington down to Fenwick Island.
