Asking the right questions before hiring a deck builder in Minnesota is the single most important step you can take to protect your investment and ensure a successful project. Not all deck contractors are created equal — the difference between a skilled, reputable builder and an inexperienced or unscrupulous one can mean the difference between a deck that lasts decades and one that fails in years. At Weatherguard Construction, we encourage homeowners across Stillwater, Woodbury, Minneapolis, and the Twin Cities metro to ask tough questions. Here are the 10 most important ones.
Question 1: Are You Licensed and Insured?
This is the most critical question and should be the first thing you ask. In Minnesota, deck contractors must hold a valid contractor's license issued by the Minnesota Department of Labor and Industry. They must also carry:
- General liability insurance — Protects you if the contractor damages your property
- Workers' compensation insurance — Protects you from liability if a worker is injured on your property
Red flag: Any contractor who cannot immediately provide proof of licensing and insurance should be eliminated from consideration. At Weatherguard Construction, we provide proof of licensing and insurance upon request without hesitation.
Question 2: How Long Have You Been Building Decks?
Experience matters enormously in deck construction. A contractor who has been building decks for 20+ years has encountered and solved countless challenges that a newcomer has never faced. They understand the nuances of Minnesota's climate, local building codes, soil conditions, and material performance.
What to look for: At least 5 years of dedicated deck building experience, with preference for 10+ years. Weatherguard Construction has 25+ years of experience in residential exterior construction, including thousands of deck projects.
Question 3: What Materials Do You Specialize In?
The best deck builders specialize in specific materials and have deep expertise with those products. A contractor who builds primarily with pressure-treated lumber may not have the skills and knowledge to properly install composite or PVC decking, which requires different fastening systems, spacing requirements, and construction techniques.
What to look for: Dealer certifications from major manufacturers. Weatherguard Construction is a certified Wolf Pro dealer, carrying TimberTech, AZEK, and Trex. Our specialization in composite and PVC decking ensures expert installation.
Question 4: Will You Pull the Permits and Handle Inspections?
Reputable deck builders handle all permitting and inspections as a standard part of their service. This includes preparing plans, submitting applications, scheduling inspections, and addressing any inspector comments. Learn more about deck permitting in Minnesota.
Red flag: A contractor who asks you to pull your own permit, suggests building without a permit, or says permits are not necessary is not a contractor you want building your deck. This is a major warning sign.
Question 5: Can I See Photos and References from Recent Projects?
Any experienced deck builder should have an extensive portfolio of completed projects and be willing to provide references from recent customers. Look for projects similar to yours in scope, material, and complexity.
What to look for: Before-and-after photos of completed decks, ideally in your area. Reviews on Google, Facebook, and industry sites like Houzz or Angi. Weatherguard Construction maintains a comprehensive portfolio and dozens of five-star reviews from homeowners throughout Maple Grove, Eden Prairie, St. Paul, and beyond.
Question 6: What Does Your Estimate Include — and Exclude?
A detailed, written estimate should clearly itemize everything included in the project and note any exclusions. Vague, one-line estimates are a recipe for surprise charges.
Your estimate should include:
- Decking material (brand, product line, color)
- Substructure materials (framing lumber, hardware, fasteners)
- Railing system (type, material, color)
- Stairs (number, width, railing)
- Footings (number, type, depth)
- Demolition and removal of existing deck (if applicable)
- Permits and inspections
- Site preparation and cleanup
- Warranty information
Red flag: Verbal estimates, handwritten estimates on scraps of paper, or estimates missing key line items. Professional contractors like Weatherguard Construction provide comprehensive written proposals.
Question 7: What Is Your Timeline?
Understanding the project timeline sets expectations and helps you plan. A reputable builder should provide an estimated start date and completion date, along with factors that might affect the schedule (weather, permit delays, material availability).
Typical timelines:
- Simple deck (200–300 sq ft): 1–2 weeks
- Standard deck (300–500 sq ft): 2–3 weeks
- Multi-level or complex deck: 3–5 weeks
Question 8: What Warranty Do You Offer on Labor?
Material warranties come from the manufacturer, but labor warranties come from the contractor. A quality deck builder stands behind their workmanship with a meaningful warranty.
What to look for: A minimum 2-year labor warranty, with preference for 5+ years. Weatherguard Construction provides a comprehensive workmanship warranty because we are confident in the quality of our installation.
Question 9: How Do You Handle Changes or Unexpected Issues?
Every construction project has the potential for unexpected discoveries — rotted rim joists behind siding, inadequate soil conditions, or design changes during construction. A professional contractor has a clear process for handling changes.
What to look for: A written change order process that requires your approval and signature before any additional work is performed. No contractor should ever incur additional charges without your explicit consent.
Question 10: What Sets You Apart from Other Deck Builders?
This open-ended question reveals what the contractor values and how they differentiate themselves. Listen for substance over salesmanship.
At Weatherguard Construction, our answer includes:
- 25+ years as a family-owned Minnesota business headquartered in Stillwater
- Certified Wolf Pro dealer with TimberTech, AZEK, and Trex
- Composite and PVC decking specialists — it is all we install
- Full-service permitting, design, and construction
- Transparent pricing with no hidden fees

Bonus: Trust Your Instincts
Beyond these 10 questions, trust your gut feeling. A great deck builder is communicative, punctual, professional, and genuinely interested in building the right deck for your home. If a contractor is hard to reach, vague in answers, or pressures you to sign immediately, move on.

Frequently Asked Questions
How many estimates should I get for my deck project?
We recommend getting at least three written estimates from licensed, insured deck builders. Compare not just price but also materials, scope, warranty, and professionalism. The cheapest estimate is rarely the best value.
Should I pay a deposit before work begins?
A reasonable deposit (10–33% of the project total) is standard practice and helps the contractor order materials. However, never pay the full amount upfront. A typical payment schedule includes a deposit, a mid-project payment, and a final payment upon completion and your satisfaction.
What if my deck builder goes out of business?
This is why choosing an established company matters. Material warranties transfer with the product regardless of the installer. However, labor warranties from a defunct company are worthless. Weatherguard Construction has been in business for 25+ years — we will be here when you need us.
How do I verify a contractor's license in Minnesota?
You can verify Minnesota contractor licenses through the Minnesota Department of Labor and Industry website. Search by company name or license number to confirm active status and check for any complaints or disciplinary actions.
