Licensing and Subcontractor Requirements

Colorado doesn't require a state GC license for bathroom remodeling, but Denver requires a city contractor license. The plumbers and electricians within your remodel must hold Colorado state trade licenses.

Ask: Do you use licensed plumbers and electricians? Can you provide their license numbers? A reputable bathroom remodeler manages licensed subcontractors and pulls all required permits.

Waterproofing Is the Most Critical Factor

The most common bathroom remodel failure is inadequate waterproofing. Ask specifically: What waterproofing system do you use in the shower? The answer should reference a specific product — Schluter Kerdi, RedGard, Wedi, or similar.

'We use cement board' is not a complete waterproofing answer — cement board is not waterproof. A contractor who can't answer this question specifically is a red flag.

Portfolio and References

Always review a portfolio of completed Denver bathrooms before hiring. Look for: consistent grout lines, quality tile work, frameless glass installation quality, and overall design cohesion.

Ask for 2–3 references from bathroom projects completed in the past 12 months. Ask specifically: Were there any leaks or water issues after completion?

The Bathroom Remodel Contract

A proper contract should specify: exact tile by manufacturer and product name, fixture brands and model numbers, waterproofing system by name, permit responsibility, milestone payment schedule, and minimum 1-year labor warranty.

Vague contracts lead to disputes. If a contractor resists specifying materials, that's a red flag.

Frequently Asked Questions

How do I find a good bathroom remodeler in Denver?

Check Google reviews, Houzz portfolios, and BBB ratings. Ask for references from recent Denver bathroom projects and call them. Verify the contractor holds a Denver city contractor license.

What waterproofing should be used in a Denver shower?

Ask for Schluter Kerdi, RedGard, or Wedi systems. These are industry-standard waterproofing membranes. Cement board alone is not waterproof and is insufficient for shower applications.

How long does a bathroom remodel take in Denver?

A standard hall bathroom takes 2–3 weeks. A master bathroom takes 3–5 weeks. Add 1–2 weeks for permit approval if plumbing or electrical changes are involved.
