Professional Door Services in Greenwich: Repair & Installation
(475) 234-2695
We’re Open Every Day From 7:00 AM to 7:00 PM
Greenwich doors face a combination almost nothing else in Connecticut does: salt air off Long Island Sound, coastal storm exposure in Old Greenwich, Riverside and Byram, hard winters inland, and a housing stock that includes both eighteenth-century colonials and large custom homes with oversized, non-standard entries. A1 Door Services works across all of it, from waterfront properties to backcountry estates to the retail storefronts along Greenwich Avenue.
Reliable Door Repair in Greenwich, CT
The Greenwich pattern is corrosion plus exposure. Salt-laden air pits hardware finishes and attacks fasteners, driving rain from a nor’easter finds any failed seal, and doors on shoreline elevations weather years faster than the same door two miles inland.
Sliding & Patio Door Repair
Waterfront and pool-side sliders take the worst of the salt air. We replace corroded and flattened rollers, repair or replace pitted bottom track, fit new latches and handles, rescreen panels, and replace fogged insulated glass units. On large multi-panel and lift-and-slide systems we service the hardware and re-level the head track so heavy panels move and seal correctly again.
Door Frame & Alignment Repair
Coastal moisture and winter freeze-thaw both attack the base of an exterior opening. We replace thresholds and sill sections, splice rotted jamb legs, re-square and re-shim frames that have settled, and rebuild jambs after forced entry. On historic Greenwich homes we repair original frames and trim rather than replacing them, matching profiles where new material is needed.
Lock, Hinge & Hardware Repair
Salt air is unforgiving on door hardware. We replace seizing deadbolts and latches, service and adjust multipoint locking systems on custom and European-style doors, replace corroded hinges and fasteners, and rekey after purchases, staff changes and contractor work. Where finishes keep failing, we recommend hardware specified for coastal exposure rather than the standard interior-grade finish.
Storm & Impact Damage Repair
Nor’easters and coastal storms drive wind and water at Greenwich shoreline properties. We repair storm-damaged doors and storm doors, replace broken glass and torn screens, rebuild water-damaged frames and thresholds, and provide emergency board-up and securement, including ahead of a forecast storm where an opening is already compromised.
Commercial & Automatic Door Repair
For Greenwich businesses we service aluminum storefront doors, automatic sliding and swing operators, sensors and activation devices, closers, panic hardware and fire-rated openings. Retail on and around Greenwich Avenue, along with offices and clinics throughout town, gets 24/7 emergency response so an entrance is never left unusable.
Door Installation for Homes & Businesses in Greenwich, CT
Installation here often means non-standard work: oversized slabs, custom widths, multipoint hardware, transoms and sidelight assemblies. We measure the real opening, remove the old unit, set and insulate the new one, fit trim to match existing millwork, tune the hardware and take the old door away, with sill pan and flashing detail specified for coastal exposure.
Entry & Patio Door Installation
We install custom and standard entry doors in fiberglass, steel, solid wood and clad wood, with sidelights, transoms and multipoint hardware. On exposed shoreline elevations, fiberglass and properly finished clad units hold up where a field-finished wood door will not, though we also install and maintain traditional wood entries where the architecture calls for one. For patios we install sliding, multi-slide, lift-and-slide and French door systems.
Interior, Closet & Barn Doors
We install interior, closet, pocket and barn doors, matching existing trim profiles and panel proportions in older Greenwich homes rather than dropping in a stock slab that reads as new. Solid-core doors are standard in our interior installations for sound control.
Locks & Smart Hardware
We install deadbolts, multipoint locks, keypad and smart hardware and keyed-alike systems across whole properties, including outbuildings and pool houses. Hardware is chosen for coastal durability as well as appearance, and we can integrate smart locks with existing home systems and set up access for household staff and contractors.
Commercial, Fire-Rated & ADA Doors
We install hollow metal doors, aluminum storefronts, fire-rated assemblies, ADA low-energy operators and panic hardware for Greenwich businesses, configured for clearance, closing force and egress requirements. Fitting accessible entrances into older retail buildings without spoiling the storefront is regular work for us.
Garage Door Installation
We install and replace sectional and carriage-style garage doors, openers, springs, cables and rollers, specifying corrosion-resistant components on coastal properties, plus the self-closing fire-rated door between an attached garage and the house.
24/7 Emergency Door Repair in Greenwich
A1 Door Services answers emergency door repair calls in Greenwich 24 hours a day, every day, including during and after coastal storms.
Emergency work covers storm and water damage, break-in damage and split jambs, broken glass, board-up and securement, doors jammed shut or stuck open, and failed automatic operators and closers on commercial entrances. Call (475) 234-2695 and describe the opening; we’ll tell you what can be secured on the first visit.
Door Installation and Upkeep for Greenwich’s Climate
Proximity to Long Island Sound changes the maintenance picture entirely. Salt-laden air deposits on hardware and finishes continuously, not just during storms, and it pits plating, corrodes fasteners and seizes lock mechanisms far faster than inland exposure. Coastal storms then push wind-driven rain horizontally against elevations that shed ordinary rain without difficulty. Inland and backcountry properties trade some of that for harder winters, with snow and freeze-thaw working on thresholds and sills.
Practical upkeep for Greenwich: rinse exterior hardware and metal thresholds with fresh water periodically, particularly on shoreline properties; specify hardware and fasteners rated for coastal exposure rather than standard finishes; check perimeter sealant and sill drainage before storm season; keep sliding tracks clean so salt and grit don’t pit the rollers; and inspect the base of exterior jambs annually, since coastal rot works from behind the trim outward.

Frequently Asked Questions
Why does my exterior door hardware corrode so quickly?
Salt in the air, continuously. It settles on hardware, works into the mechanism and attacks plating and fasteners. Rinsing with fresh water helps, but the durable answer on a shoreline property is hardware specified for coastal exposure, with corrosion-resistant internal components rather than standard plating.
Can you service multipoint locks on custom and European doors?
Yes. We adjust, repair and replace multipoint locking systems, including gearboxes, strikes and handle sets, and we realign doors where the frame has moved and the multipoint no longer engages cleanly at all points. Parts for many systems are available, so replacing the entire door is rarely necessary.
My entry door is an unusual size. Does it have to be custom-made?
Not always. Where the frame is sound, we can often build the new jamb to the existing opening or fit a slab to the original frame. Where a custom unit genuinely is the right answer, we handle the measurement and specification so it fits the opening rather than forcing the opening to fit a stock size.
What should I do about my doors before a nor'easter?
Check that weatherstripping contacts along the full perimeter, that deadbolts and multipoints engage fully, that sliding panels seal at the interlock, and that perimeter sealant is intact. Secure or remove anything that could catch wind, and call us in advance if an opening is already compromised. We can board up ahead of the storm rather than after.
Can you repair the original doors on a historic Greenwich home?
Usually. Loose joinery, rotted bottom rails, worn mortise pockets and failed glazing are all repairable, and repairing keeps the original proportions and detail that a modern replacement cannot reproduce. Where new material is needed, we match profiles.
Do you cover Old Greenwich, Riverside and Cos Cob?
Yes. We serve Greenwich, Old Greenwich, Riverside, Cos Cob, Byram, Glenville and the backcountry. Provide the address when booking and we’ll confirm scheduling in advance.
