Electric Strike Installation in Cypress, TX 77433

The door decides the hardware, not the other way round

An electric strike is not a lock. It replaces the fixed strike plate in the frame with a powered keeper — a hinged jaw that either holds the latch bolt or swings out of its way on command. The lock on the leaf is never touched, and the inside lever still retracts the latch by hand, powered or not.

Three door families turn up again and again in 77433, and they do not behave alike:

• Builder fiberglass and steel entry doors in Bridgeland, Towne Lake, Marvida and Cypress Creek Lakes — frequently fitted with a multipoint lock, which changes the answer completely.
• Interior, side and garage-to-house doors with a cylindrical lockset on a 2-3/8 inch backset. The simplest candidates in a Cypress house.
• Hollow metal and aluminum storefront doors in the centres along US-290, Fry Road, Mason Road and Barker Cypress. Purpose-built for this, if the frame prep is right.

We identify which you have before a part is ordered. A strike cut into the wrong door is money spent on an opening that still will not release.

Why a new-build front door may refuse a strike outright

This is the commonest disappointment on a house built in the last fifteen years, and better heard at the estimate than on installation day. A multipoint lock throws a centre latch plus two rods — one into the head jamb, one into the sill — when you lift the lever. Builders specify them on tall fiberglass slabs because they pull the door flat to its weatherstrip and stop a sun-facing leaf bowing.

A strike sits in the frame beside the centre latch. It can release that latch and nothing else. The top and bottom rods stay buried, and the door does not move. No strike at any price solves this.

Three honest ways forward:

• Put the credential on a different opening. The garage-to-house door, a side entry or a courtyard gate usually serves the real need.
• Swap the multipoint for a motorised unit that retracts all three points electrically. That is a lock replacement, matched to the existing door prep.
• Convert to a conventional single-latch lockset, sometimes possible when the slab was prepped for both patterns.

Half an inch of pine, a shim gap, and no margin for error

A production jamb is a thin board — often finger-jointed pine a shade over half an inch — with a shim space behind it and a jack stud behind that. A strike body needs a pocket cut clean through the jamb into that void: deep enough for the case, wide enough for the faceplate, with the screw ears on solid material rather than air. Too deep and you are into the stud; too shallow and the keeper binds every close. We scribe and chisel rather than route freehand.

Two details decide whether the door is genuinely secure afterwards:

• The deadlatch plunger must land on the faceplate. That small second plunger beside the main latch is what stops a card being slipped past the bolt. If the pocket is placed so the plunger drops into the opening with the latch, the door can be shimmed in seconds — and it still tests perfectly with a fob, which is why the defect survives so many installs.
• Weatherstrip compression is a real load. A tight exterior door presses its latch hard into the keeper. Most strikes cannot swing against that; a few models are built to. Closer tension, the sweep and seasonal swell of a west-facing slab all add to it.

Cable leaves the back of the pocket through a small bore into the stud cavity, then runs to the attic or down to the structured panel. Cypress attics are brutal May through September, so we book those pulls for early morning.

Suites on 290, Fry and Mason: call before the ceiling closes

Half our strike work in this ZIP is commercial — dental and veterinary practices, small offices, retail taking a landlord shell. The cheap version happens before the grid goes in; the expensive version eight months later through finished drywall.

• Hollow metal frames normally arrive with a factory cut-out and an internal strike box. A grouted frame has to have that fill cleared first, which is a different afternoon entirely.
• Aluminum storefront entries need a strike built for narrow-stile hardware and sized to the specific latch on the door. A generic box from a supply house will not fit.
• A conduit stub from each controlled frame to above the ceiling, placed at rough-in, removes the most expensive line item from the job.
• Plenum-rated cable wherever return air travels the ceiling cavity. Riser cable up there is a fire-marshal problem you inherit at the next inspection.
• The head-end wants a ventilated wall in conditioned space, not a sealed box above a ceiling where the standby battery cooks.

We walk the shell with you and your contractor and mark openings, conduit paths and the panel wall on the plan while changing them still costs nothing.

Fail-secure, fail-safe, and which one a fire door permits

Every strike is one or the other, and the words run opposite to most people’s instinct. Fail-secure holds the latch unpowered and releases when energised: lose power, the door stays locked from outside. Fail-safe holds when energised and releases when power is removed: lose power, the door is open.

Either way the inside lever or panic bar still retracts the latch by hand, so people can always get out. That is the structural advantage over a magnetic lock, which genuinely holds a door shut and therefore brings a stack of life-safety requirements with it: sensor release, an emergency push button, release on fire alarm. A strike sidesteps all of it because it never fights egress.

One rule we do not bend: a fire-rated opening must stay positively latched, because the rating depends on the latch holding the leaf in the frame as it warps under heat. That means a fail-secure device listed for fire doors, and no fail-safe strike on a rated opening. Look for the metal label on the hinge edge or the frame rabbet — we check every commercial opening for one before quoting.

Duty rating, voltage drop, and the diode nobody installs

A strike that works on the bench and misbehaves on the wall is almost always electrical rather than mechanical.

• Duty rating. An intermittent-duty strike is meant to be energised in short bursts; hold it open through a delivery window and the coil overheats. Anything unlocked for long stretches needs a continuous-duty unit.
• AC or DC. Alternating current gives the familiar buzz that tells a visitor to push now; direct current is silent. Many strikes are field-selectable between 12 and 24 volts, and 24 survives a long run far better.
• Voltage drop. Each strike draws a few hundred milliamps, with the data sheet governing the exact figure. Push that down two hundred feet of thin conductor and the strike sees materially less than the supply makes. The symptom is a jaw that chatters, or works in the morning and refuses by four.
• Suppression. A DC coil dumps a reverse spike every time it drops out. A suppression diode across the coil, fitted the right way round, protects relay contacts and stops that spike resetting readers on the same bus. It costs pennies and is left out constantly.

Five things that bring an installer back to Bridgeland

1. A thrown deadbolt. The strike releases the latch only. Someone throws the deadbolt at night and by morning the badge looks dead. If one credential is to rule the door, the deadbolt has to go or be replaced with hardware the system can drive.
2. Hardware bought online before the door was measured. A cut frame cannot be returned, and the wrong body means a second cut in a jamb that barely took the first.
3. The plunger in the pocket. Invisible in testing, and the reason a door that badges perfectly can still be opened with a plastic card.
4. A door that has dropped. New houses settle. A hinge-sagged leaf shifts the latch a quarter inch and the keeper starts catching; many first-year returns are shims and a closer adjustment, not electronics.
5. No request-to-exit. Without a REX or bar switch to shunt the door contact, staff leaving generate a forced-door alarm every evening until someone silences the system for good.

What actually moves a 77433 estimate

We do not quote a door over the phone; every variable that matters is physical. On site we look at:

• How many openings, and whether they are residential wood, hollow metal or aluminum storefront.
• Whether a frame cut-out and strike box already exist.
• The lock already fitted — cylindrical, mortise, multipoint, rim exit device, or a vertical rod device that needs a different solution altogether.
• Cable distance and route: an open shell ceiling is a different job from a finished one-story with no chase.
• Whether a controller, supply and battery exist, or the head-end is new.
• Latch monitoring and a door position switch reporting to the panel, or simply a release.

You get an itemised written quote listing hardware by model and labour separately.
