Sliding Doors near you

CPSC's guidelines note that according to the Centers for Disease Control and Prevention, drowning is the leading cause of unintentional death for one to four year old children, and that each year nearly 300 children under age five drown in swimming pools. Where the house wall forms part of the enclosure, the guidelines say to install door alarms on all doors leading to the pool area and to make sure the doors have self-closing and self-latching devices or locks that are beyond the reach of children. The same guidance applies to all the walls surrounding a pool located completely inside a house.

The alarm specification is unusually detailed, which makes it easy to check what a supplier is selling you. CPSC says alarms should meet the requirements of UL 2017, General-Purpose Signaling Devices and Systems, Section 77, and lists the features: the alarm sound should last for 30 seconds or more and start within 7 seconds after the door is opened; it should be loud, at least 85 decibels measured 10 feet away from the alarm mechanism; it should be distinct from other sounds in the house such as the telephone, doorbell and smoke alarm; and it should have an automatic reset feature to deactivate the alarm temporarily for up to 15 seconds so adults can pass through, with the deactivation switch, a keypad or a manual switch, located at least 54 inches above the threshold and out of the reach of children.

The guidelines also say the alarm should sound when the door and the screen are opened, which is the detail people miss: a child who slides the screen open has already left the house. CPSC is clear that barriers are not childproof and can never replace adult supervision, and notes that some states and localities have incorporated its guidelines into their building codes, so check what your own jurisdiction requires before assuming an alarm is optional.

This is the most useful distinction on a patio door label, and it is easy to verify. Under the ENERGY STAR Version 7.0 specification, effective October 23, 2023, windows, sliding glass doors and skylights are all judged against the criteria for a given climate zone, while swinging doors are judged against the criteria for a given glazing level. So a slider in the Northern zone is being held to a U-factor of 0.22 with a solar heat gain coefficient of 0.17, and in the Southern zone to 0.32 and 0.23, in exactly the way a window in the same wall would be.

Air leakage separates them again. The specification sets 0.3 cubic feet per minute per square foot for windows, sliding doors and skylights, and 0.5 for swinging doors, demonstrated either by displaying the figure in the air leakage portion of the temporary NFRC label or by one of the structural certification labels the specification names. If you are weighing a slider against French doors for the same opening, that difference is a real one, and it is one of the few places where the two options can be compared on a published number rather than on impressions.

A large share of sliding door problems are hardware problems, and hardware is a service call rather than a replacement. Rollers, keepers, handles, interlock weatherstripping and even track capping are replaceable on most doors made in the last few decades, and a technician who arrives, removes the panel, cleans the track and fits new rollers has usually solved the complaint for a fraction of the cost of a new unit. Ask whether parts are available for the line before accepting that the door has to go.

Glass is its own category. A failed sealed unit can normally be replaced in the existing panel, which keeps the frame, the flashing and the finishes untouched. A cracked or broken pane in a patio slider is a different matter, because the standard treats sliding glass doors of the patio type as its most demanding category, so the replacement is a made-to-size ordered item rather than something cut on a truck.

Replacement earns its place when the frame itself is the problem: a sill that has rotted or settled, a frame racked out of square in the opening, corrosion at the fasteners, or a line whose parts have been discontinued so every future repair depends on salvage. It also earns its place when the opening is changing size, at which point the job stops being a door swap and becomes structural work with permits. Get the diagnosis from someone who is not also selling you the door, if you can.

A sliding door frequently serves a bedroom, a basement family room or a converted space, and in those rooms it may be doing double duty as the emergency escape and rescue opening. The Minnesota Department of Labor and Industry, publishing the 2020 Minnesota Residential Code, which adopts the 2018 International Residential Code with amendments, states that basements, habitable attics and every sleeping room shall have not less than one operable emergency escape and rescue opening, that where basements contain sleeping rooms an opening is required in each sleeping room, and that those openings shall open directly into a public way, or to a yard or court that opens to a public way.

Two provisions govern how it has to work rather than how big it is. Emergency escape and rescue openings shall be operational from the inside of the room without the use of keys, tools or special knowledge, and the required clear opening has to be obtained by the normal operation of the opening from the inside. That is a direct constraint on the security hardware people add to sliders: a bar in the track, a pin through the frame or a keyed lock on the inside can quietly disqualify the room's only escape route. The requirements that apply at your address are the ones your jurisdiction adopted and enforces, so ask the building department before fitting anything to a door in a sleeping room.

Sliding door pricing separates cleanly into three tiers, and knowing which tier you are in prevents most of the confusion. A hardware service call is priced on labor and parts. A glass replacement is priced on the size and make-up of the unit and the fact that it is manufactured to order. A door replacement is priced on the panel count, the opening, the condition of the sill discovered once the old unit is out, access for a heavy glazed panel, whether an alarm or pool-barrier hardware is part of the scope, and whether the opening is changing. Ask which tier a quote belongs to before comparing it to another.

LokalMatch is only the way the conversation starts. You describe the door once, with the opening width, the panel count, what the door is doing wrong, whether it faces a pool or a deck and whether the room it serves is a bedroom, and door companies covering your area contact you directly. They pay LokalMatch for the requests they take; you pay nothing to use it. LokalMatch does not repair or install doors, does not set prices, and does not vet, rank or recommend any company, so checking licensing where your state requires it, insurance and the written scope stays with you.
