The terms of this expressed warranty excludes failures due to damage due to freight carriers, common carriers, private transportation or any other means of transportation or handling after shipping from Sing Core.
The procedure for obtaining performance of the obligations of this warranty is as follows: if you believe your entry door to be defective, contact the contractor for inspection. If the contractor determines the Sing product or parts thereof to be defective, the manufacturer at its exclusive option will repair; provide a new product or part of a product after having determined that it does not conform to the limited warranties contained herein. The manufacturer reserves the right to discontinue or make changes in any of its products. If the products covered by this warranty are not available, the manufacturer shall have the right to substitute a product that is of equal quality or value. The manufacturer will ship the replacement product or part to the nearest authorized dealer and the purchaser must pay for any and all labor necessary to install such product or part and for the transportation from the nearest authorized dealer to his/her residence.
Any claim must be accompanied by a copy of the contract evidencing purchase of the Sing Core products.
SING CORE SHALL NOT BE LIABLE TO PURCHASER FOR CONSEQUENTIAL DAMAGES, SUCH AS, BUT NOT LIMITED TO, DAMAGES OR LOSS TO OTHER PROPERTY OR EQUIPMENT, LOSS OF USE, OR CLAIMS OF SERVICE INTERRUPTION, FOR BREACH OF ANY WRITTEN OR IMPLIED WARRANTIES ON ITS PRODUCT.
PURCHASER’S EXCLUSIVE REMEDY SHALL BE THE REPLACEMENT OF DEFECTIVE FINISH, COMPONENTS, OR PARTS, ALL AS PROVIDED HEREIN.

Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to purchaser.
THIS WRITING CONTAINS THE ENTIRE AGREEMENT BETWEEN SING CORE AND PURCHASER. DEALERS, CONTRACTORS, APPLICATORS, OR DISTRIBUTORS OF SING CORE PRODUCTS HAVE NO AUTHORITY TO GIVE WARRANTIES ON SING CORE’S BEHALF, THAT ARE DIFFERENT FROM OR EXCEED THOSE LISTED HEREIN. PURCHASER SHOULD THEREFORE EXAMINE THIS WARRANTY CAREFULLY.
ALL WARRANTIES, WHETHER EXPRESSED OR IMPLIED, WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE ARE LIMITED TO THE TERMS HEREOF.
Some states do not allow limitations on how long an implied warranty lasts; so the above limitations may not apply to purchaser.

Important Note: Keep your receipt of purchase and the receipt from the contractor who made the installation in your Home showing the date of installation and the address in a safe place.

Receiving Instructions and Maintenance
________________________________________
Arrival and Storage of Sing Products
Upon Arrival
• Sing products are delivered unfinished
• Offloading may require a dock or forklift
• Additional millwork or door shop work is required before the product is retail-ready
________________________________________
Temporary Appearance of Warp
• When multiple door blanks are shipped stacked or side by side, exterior pieces may appear warped
• This is normal and does not indicate a defective product
• Proper acclimatization will restore the panel to true flat condition
________________________________________
Acclimatization Procedure
• Stand the door on its long edge
• Keep it at least 12″ away from walls or other surfaces
• Allow up to 72 hours for acclimatization
• Re-measure after acclimatization
• If the door does not return to true flat, document and contact Sing Core
________________________________________
Proper Storage
• Store doors vertically at all times
• Do not lean doors against walls
• Store in a clean, dry, climate-controlled environment
If doors must be stored stacked
• Wrap in plastic
• Place plywood sheets underneath and on top of the stack
• This helps maintain even acclimatization
________________________________________
Jobsite Conditions
• Deliver doors only after plaster, concrete, and drywall mud have fully cured
• Do not store doors in damp basements or uncontrolled environments
• Moisture exposure will void the warranty
• Unequal moisture on opposite sides of a panel may cause warping
________________________________________
Fabrication
Safety
• Wear protective eyewear and a filter mask when cutting
• Position panels so saw blades enter from the exterior face first to prevent chipping
________________________________________
Blocking and Machining
• Blocking locations are marked in pencil
• Re-mark blocking if trimmed or sanded away
• All drilled holes and cutouts must be filled and sealed with an approved sealer
Failure to seal machined areas may void the warranty.
________________________________________
Finishing Requirements
General Requirements
• All six sides of the door must be fully sealed
• Includes top and bottom edges
• Use a high-quality finish rated for at least 15 years
• Primer or stain alone is not sufficient
________________________________________
Surface Preparation
• Sand the entire door surface with fine sandpaper before finishing
• Remove handling marks and oils
________________________________________
Timing
• After hardware fitting, apply a sealer or first finish coat promptly
• The sooner finishing begins after acclimatization, the better the door will perform
• Complete the finishing process without long interruptions
________________________________________
Finish Quality
• Variations in gloss, texture, or appearance caused by field finishing are not warrantable
• Consult your finish supplier for proper techniques
• Finishing should be performed or overseen by a professional millwork company with at least 5 years of experience
________________________________________
Sun Exposure and Color
• Avoid dark stains or paints on doors exposed to direct sunlight
• Black or very dark exterior doors exposed to sunlight are not covered under warranty
________________________________________
Exterior Overhang Requirement
All exterior doors must have a sufficient overhang.
Minimum requirements
• Overhang depth must equal half the distance from the bottom of the door to the underside of the overhang
• Overhang width must extend half of that same distance beyond each side of the door
This protects the door from weather exposure and is required for warranty eligibility.
________________________________________
Warranty-Critical Notes
• Doors must be protected from excessive heat, dryness, humidity, moisture, and direct sunlight
• Balanced skins are required to maintain warranty
• All finishing plans must be discussed with Sing Core in advance
• Mirrors, tile, or similar applied materials will void the warranty
• Only skins applied by Sing Square Log Home Inc. are covered
• Skins thicker than 1/8″ require prior written approval
• Machining of face grooves, reveals, or decorative cuts voids the warranty
Customers are responsible for notifying Sing Square Log Home Inc. in writing of all finishes and skins applied.
________________________________________
Maintenance
• Exterior finishes deteriorate over time
• Inspect exterior doors at least once per year
• Refinish immediately if deterioration is visible
• Refinish all six sides of the door
• Keep inspection and refinishing records to maintain warranty
