Frequently Asked Questions - All Objections Addressed

What's the difference between inside and outside corner miters? ▼
Inside corner miters are used where two gutter sections meet at an inward corner (like the inside corner of an L-shaped building), while outside corner miters are used at outward corners (like the outside corner of a building). Both create perfect 90° transitions but are engineered for their specific applications. Most homes need both types for complete gutter systems. Simple rectangular buildings typically need 4 outside corners, while complex architectural designs require a combination of both inside and outside configurations.
Will this 6K box miter work with my existing gutters? ▼
This miter is designed specifically for 6K gutter systems and will only work with 6K gutters. It will not fit 5K, 7K, or other gutter profiles. 6K gutters are typically used in commercial applications and large residential installations requiring higher water capacity. If you're unsure about your gutter size, measure the top opening or contact us with photos. Our Damascus location staff can help identify your gutter system and ensure you order the correct corner configuration.
How do I choose the right color to match my existing gutters? ▼
We offer 30+ professional colors including exact matches for most standard gutter colors. Popular 6K choices include 30 Deg. White for commercial buildings, Dark Bronze and Musket Brown for residential applications, and Black for modern architectural designs. If you have existing gutters, take a photo in natural daylight and contact us - we can help identify the closest color match. For large commercial projects, we also offer custom color matching services to ensure perfect coordination with your building exterior and architectural specifications.
Can I install this myself or do I need a professional contractor? ▼
Professional installation is strongly recommended for several critical reasons: working at height requires proper safety equipment and fall protection, precise alignment is essential for leak-proof performance, proper sealing techniques with professional-grade sealants are critical for longevity, and improper installation can void warranties and create expensive water damage. Professional contractors have the specialized tools, extensive experience, proper insurance coverage, and proven techniques for safe, guaranteed installation that meets building codes and manufacturer specifications.
What's included with my box miter purchase? ▼
Each box miter includes the precision-engineered corner piece in your selected color and configuration (inside or outside). Professional installation hardware (screws, rivets) and sealant are typically purchased separately as they vary by installation method and contractor preference. We provide detailed installation specifications with each order and can recommend compatible professional-grade sealants (typically urethane or silicone-based) and appropriate fasteners for your specific project requirements and local building code compliance.
How many corners do I need for my home or building? ▼
Count each corner where gutters change direction - most simple rectangular buildings need 4 outside corners, while L-shaped or complex designs may need both inside and outside corners. Walk around your building perimeter and identify each 90-degree turn in the gutter system. Take photos of your roofline or provide your building address - our Damascus staff can help calculate exactly what you need including proper inside/outside configurations for complete coverage. Commercial buildings with complex rooflines may require professional site assessment.
What shipping options are available nationwide? ▼
We ship to all 50 states with multiple expedited options: standard ground shipping (5-7 business days), expedited shipping (2-3 business days), and overnight shipping available for urgent repair projects. All box miters are professionally packaged with protective materials to prevent damage during transit. Local Damascus area customers can choose free pickup at our showroom during business hours or arrange local delivery for large commercial orders. Bulk commercial orders qualify for special freight shipping rates and direct jobsite delivery coordination.
Do you offer volume discounts for multiple corners? ▼
Yes, we offer comprehensive volume discounts for multi-corner residential orders, special contractor pricing for professional installers and building professionals, and wholesale commercial rates for large development projects, apartment complexes, and commercial construction. Discounts typically start at 4+ corners for residential and increase progressively with quantity. Contact us at 503-496-7017 with your complete project requirements for custom pricing - we work with homeowners, general contractors, gutter installation companies, and commercial developers to provide competitive rates for any size project while maintaining our quality standards.
What's your return policy for box miters? ▼
We offer a 30-day return policy on unopened, unused box miters in original undamaged packaging. Custom colors and special-order finishes are non-returnable unless defective or incorrectly manufactured. For defective products or manufacturing errors, we provide immediate replacement at no charge. We work closely with customers during the selection process to ensure proper configuration (inside vs. outside), correct color matching, and accurate quantity calculations to minimize returns and ensure project success. Professional consultation available before purchase to prevent ordering errors.
Can you provide technical support for my gutter project? ▼
Yes, our experienced Damascus team provides comprehensive technical support including: corner configuration guidance for complex rooflines, color selection assistance with physical samples, precise quantity calculations based on building dimensions, detailed installation specifications and best practices, recommended sealant and fastener specifications, building code compliance guidance, and referrals to qualified local professional contractors when needed. Call 503-496-7017 for expert consultation and professional project planning assistance. Our staff averages 15+ years of gutter industry experience.
