Door & window repair, statewide
About Delaware Doors & Windows
We fix what other companies want to replace
A door and window repair company serving homeowners across all three Delaware counties. No showroom, no sales appointment, no financing pitch — just technicians who turn up, work out what actually failed, and fix it.

It started with a question nobody was answering honestly
Why does a sticking patio door come back as a quote for a new patio door? We watched Delaware homeowners get told their slider, their windows, their entire rear elevation needed replacing — when the actual fault was a pair of salt-corroded rollers, a parted sash cord, or a strike plate three millimetres out of line.
Replacement is a far bigger sale. It is also a far bigger disruption, a far bigger bill, and very often completely unnecessary. So Delaware Doors & Windows was built to do the other job: the smaller one, the one that takes diagnosis rather than a sales script.
That is still the whole business. We repair. We recommend replacing something only when it genuinely cannot be saved, and when we do, we show you exactly why.
An original sash, properly repaired, will outlast the window sold to replace it.

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.
Four things we hold to
Not a mission statement. Just how the job actually gets done.
Repair first
We recommend replacement only when a repair genuinely will not hold — and then we show you the reason, not just the price.
Diagnose honestly
Sometimes nothing is broken. Winter condensation on the room side of your glass is indoor humidity, not a failed unit, and we will say so rather than sell you glass.
Specify for the location
Corrosion-resistant hardware within reach of salt air, standard components where they will last. The same repair needs different parts in Newark and in Dewey Beach.
Fix the cause
New rollers on a ruined rail, or a new lock on a dropped door, buys you a season. We deal with what actually caused the failure.

The people who turn up at your door
This is a specialist trade and we staff it that way. Our technicians work the same systems every day — aluminium and vinyl sliders, multi-panel patio doors, original double-hung sash with cords and weights, mortise locks, and hardware from manufacturers that closed decades ago.
They arrive in a stocked van carrying the common roller, track, hardware and screen components, so the job usually finishes on the first visit. Drop cloths go down, and the old parts and broken glass leave with them.
They will also talk you through what they found. If you want to understand why your doors only stick in August, or why the hardware on the ocean side of the house failed first, ask — that conversation is part of the job.
One sticking door, or a whole building
Whether it is a single patio slider or a rental property full of them, the process does not change: inspect, quote, repair.
Homeowners
Single-visit repairs on patio doors, windows, glass and hardware.
Landlords
Turnover work and tenant repair requests, including seasonal coastal rentals.
HOAs and condos
Consistent repairs across many units with one point of contact.
Small commercial

All three counties, coast to line
Delaware Doors & Windows is a statewide company. We cover New Castle County from Wilmington through Newark, Bear and Middletown; Kent County including Dover, Smyrna, Milford and Camden; and Sussex County from Lewes and Rehoboth down through Millsboro, Seaford, Georgetown and the beach towns to Fenwick Island.
Because we are mobile, there is no showroom to drive to. A technician comes to your home or property, diagnoses the problem in front of you, and in most cases completes the repair the same day.

What you can hold us to
No fine print, no pressure, and no quote that changes once the work has started.
A firm price, first
You get the number before we start, and it does not move once we are working.
Free estimates
No charge to look, and no obligation once we have looked.
Repair over replacement
We do not sell replacement doors or windows, so we have no reason to push one.
Coastal-grade hardware
Corrosion-resistant components near the water, where standard parts do not last.
All three counties
New Castle, Kent and Sussex — nowhere in Delaware is out of the way.
Work done at your property
Mobile service, so nothing has to be taken away and returned.
