Why the Receiving Inspection Matters

Patio doors are large glazed assemblies with frames, panels, tracks, rollers, locks, handles, screens, insulating glass, weatherstripping, and finish surfaces. Damage or an ordering discrepancy can involve only one component while remaining difficult to see through shipping material.

If the discrepancy is discovered immediately, the parties can document when and where it was found. If the product is moved several times, left unprotected, or partially installed before inspection, determining what happened becomes more difficult.

Contractors can review available products through Suburban Wholesale & Supply’s Gentek door collection . Information about the new construction product is available on the Gentek Model 1100 patio door page .

Prepare Before the Delivery Arrives

Receiving should not begin when the delivery vehicle reaches the site. Assign responsibility in advance and prepare a safe place where the door can be inspected without interfering with workers, vehicles, or other materials.

• Keep the approved quote and order confirmation available.
• Have the opening sketch, measurements, handing diagram, and finish selections ready.
• Know which accessories, screens, handles, and loose components should be included.
• Prepare a clean, dry, secure storage area protected from construction traffic.
• Arrange enough trained people and suitable equipment to handle the product safely.
• Have a phone or camera available for dated photographs.
• Know who must be contacted if damage or a discrepancy is discovered.

Large patio doors can be heavy and awkward. The number of handlers and type of equipment should be based on the actual unit, packaging, glass, site access, and manufacturer requirements. Do not improvise a lift that places workers, glass, or the frame at risk.

Match the Product to the Paperwork

Begin with identity rather than appearance. A patio door can look correct from several feet away and still have the wrong dimensions, glass package, operating direction, grid profile, or finish.

Inspect the Packaging Before Unwrapping

Examine the outside of the packaging before it is removed. Crushed corners, torn wrapping, broken bands, displaced protective material, punctures, water exposure, and impact marks can help identify areas that require closer inspection.

Photograph the complete packaged unit and any suspicious area before moving or opening it. Include wide views that establish the condition of the entire product and close views that show specific damage.

Packaging damage does not automatically mean the door is damaged, and intact packaging does not prove that everything inside is correct. It is evidence that should be preserved as part of the inspection record.

When signing delivery paperwork

• Count the units and separate packages.
• Compare identifying information with the order.
• Note visible packaging or product damage according to the delivery procedure.
• Avoid describing an uninspected product as undamaged.
• Keep copies of the delivery record and supporting photographs.

Inspect the Vinyl Frame and Nail Flange

Examine the frame from several angles under good lighting. Look for cracks, gouges, distortion, separated joints, finish damage, and signs that the frame has been twisted or placed under concentrated pressure.

On the Gentek Model 1100, pay particular attention to the integral nail flange. Gentek lists the fully fusion-welded sash and frame with integral nail flange as a principal product feature. The flange must be suitable for the manufacturer’s intended fastening and flashing process.

Frame inspection points

• Fusion-welded frame and sash corners
• Integral nail flange, including corners and transitions
• Head, jamb, and sill alignment
• Roller track and screen track
• Weatherstripping and interlock components
• Drainage and weep openings
• Interior and exterior finish surfaces
• Protective films and temporary shipping components

Do not attempt an undocumented field repair to a cracked frame, damaged nail flange, broken weld, or distorted component. Contact the supplier and obtain direction before altering the product. A repair that appears reasonable may conflict with manufacturer instructions, certified construction, or warranty requirements.

Inspect the Glass Without Making Unsupported Conclusions

Check the glass from both sides under normal lighting. Look for cracks, chips, impact marks, edge damage, scratches, debris, and obvious visual irregularities. Keep in mind that glass inspection standards may define viewing distance, lighting, background, and allowable conditions.

Do not assume that every reflection or visual distortion indicates defective glass. Large insulating-glass units can produce reflections that change with temperature, pressure, viewing angle, and exterior surroundings. Conversely, do not dismiss a crack or edge impact as merely cosmetic.

Photograph a suspected issue from several angles and record where it appears. Do not use markers, metal tools, razor blades, or aggressive cleaners on the glass or frame unless approved by the manufacturer.

Gentek’s care information advises against abrasive cleaners, solvents, paint removers, and sharp objects on its windows and patio doors. Follow the current care instructions for the actual product.

Check the Operating Panel, Rollers, Lock, and Screen

A patio door may not be ready for final operational adjustment while it is still packaged or unsupported. Do not force the panel, operate a lock against a misaligned keeper, or lift components without following the product instructions.

Once the manufacturer’s receiving procedure permits inspection, confirm that the major operating components are present and visibly intact. The Model 1100 currently includes adjustable tandem rollers, an extruded aluminum roller track, and a screen with four-point roller adjustment.

• Check that rollers and adjustment locations are not visibly damaged.
• Inspect the track for dents, bends, contamination, and concentrated impact.
• Verify that handles, locks, keepers, keys, and covers match the order.
• Inspect the screen frame, mesh, corners, rollers, and pull or handle.
• Confirm that weatherstripping is present and not crushed, torn, or displaced.
• Keep loose hardware identified and secured with the correct door.

Protect Labels and Product Identification

Product labels can contain information needed for inspection, code verification, product identification, and future service. Gentek’s care guide states that its warranty label provides identifying information such as the serial number, product size, and date of manufacture.

Photograph relevant labels before installation and preserve required documentation. Do not remove permanent or required labels merely to improve appearance during construction. Temporary labels and adhesive should be removed only as directed.

For safety glass, certification, energy, or code labels, confirm the project’s documentation requirements before removal. Some markings are permanently etched or applied to the glass, while other labels may be intended for inspection and later removal.

Understanding the AAMA Gold Label

The Fenestration and Glazing Industry Alliance administers the AAMA Gold Label Certification Program. The program identifies qualifying windows, doors, and skylights manufactured under a certification process involving product testing, plant inspections, and ongoing program requirements.

When a project requires certified performance, the receiving inspection should confirm the label and compare its information with the approved order and project requirements. Record the label before it is covered by flashing, trim, or interior finishes.

A Gold Label should not be interpreted as proof that the door was delivered without damage or that it will be installed correctly. Product certification, receiving condition, and installation quality are related but separate responsibilities.

Store the Patio Door Safely

Follow Gentek’s current handling and storage requirements for the particular patio door. In the absence of a project-specific instruction, do not invent a storage method based on convenience alone.

The storage area should protect the unit from water, mud, welding, grinding, sparks, masonry cleaning, drywall compound, paint, solvents, moving equipment, falling objects, and uncontrolled construction traffic. It should also prevent the door from becoming an unstable obstruction.

General storage precautions

• Use the orientation and support method required by the manufacturer.
• Keep the unit secure so it cannot tip, slide, rack, bow, or fall.
• Support it without concentrating pressure on the frame, track, flange, glass, or hardware.
• Keep it away from standing water and uncontrolled moisture.
• Protect it from direct jobsite impacts and material stacked against it.
• Do not use the packaged door as a shelf, workbench, or support.
• Keep identification and accessories together with the correct unit.
• Limit unnecessary movement between delivery and installation.

Vinyl and insulating-glass products can be affected by excessive heat and concentrated solar exposure. Do not cover or store the door in a way that creates uncontrolled heat buildup. Follow the manufacturer’s requirements for packaging, ventilation, and exposure.

Keep Jobsite Materials Away from the Door

Several common construction activities can damage a patio door even when the door is not directly involved in the work.

Temporary protection should be compatible with the product and should not trap damaging moisture or heat. Do not apply unapproved tape directly to visible finished surfaces.

What to Do When a Problem Is Found

1. Stop moving or altering the affected component. Prevent additional damage and preserve the condition in which the problem was found.
2. Photograph the complete door and specific issue. Include packaging, labels, order numbers, scale references, and surrounding conditions.
3. Write a factual description. State what is visible, where it is located, and when it was discovered. Avoid guessing about responsibility or cause.
4. Preserve packaging and loose components. Do not discard materials that may help identify shipping or handling conditions.
5. Contact the supplier promptly. Follow the applicable delivery, freight, warranty, or service procedure.
6. Wait for direction before repairing or installing. An unauthorized modification can complicate evaluation and may affect certified performance or warranty coverage.

Suburban Wholesale customers can use the contact page to reach the team regarding an order or product question. Have the order information, photographs, labels, and a clear description ready.

Apply InstallationMasters Principles Before Installation

FGIA describes InstallationMasters as a nationwide training and certification program for installers of windows and exterior glass doors in residential and light commercial construction. Its curriculum extends from initial site inspection through installation, final cleaning, and maintenance.

The receiving inspection fits naturally within that process. An installer should understand what product was ordered, whether it arrived in suitable condition, how it must connect with the wall, and which manufacturer instructions apply before installation begins.

InstallationMasters training does not authorize a contractor to ignore Gentek’s instructions or make unapproved repairs. FGIA specifically notes that manufacturer instructions should take precedence.

Preinstallation Verification

Perform a second documented inspection shortly before installation. Storage conditions, other trades, weather, and additional handling may have changed the product’s condition since delivery.

• Reconfirm the product, dimensions, handing, glass, colors, grids, and hardware.
• Verify that the frame, flange, glass, track, screen, and weatherstripping remain intact.
• Compare the physical unit with the prepared rough opening.
• Confirm that installation instructions and required materials are onsite.
• Verify the sill, flashing plan, fasteners, shims, sealants, and insulation.
• Confirm that weather and jobsite conditions permit proper installation.
• Make sure the opening can be secured if an unexpected problem stops the work.
