Castle Rock Service
Castle Rock underdeck maintenance by Undercover
Maintenance plans bundle annual cleaning, scheduled inspection, sealant touch-up, hardware retorque, and priority access for any in-warranty repair. Most underdeck issues caught at 6 to 12 months show up as 30-minute fixes; the same issue caught at 4 years can mean panel replacement, water damage, or framing repair. Maintenance is the cheapest insurance available against the second outcome.
Castle Rock plans run on an annual or biennial cadence depending on your tree exposure and elevation. We schedule the visit 12 months out, send a reminder, and confirm 1 week before. You do not need to be home — we work from outside the deck and email a photo report when complete.

Inspection scope
What we check every visit
Each maintenance visit covers panel surface and finish condition, gutter slope and clearance, downspout flow test, all visible flashing and sealant, hardware torque on perimeter brackets, and any visible deck framing in contact with the underdeck. We email a written report with photos and any recommended action items within 48 hours of the visit.

Cost and schedule
Plan tiers and investment
Castle Rock maintenance plans run $295 to $650 per visit depending on system size and visit frequency. Annual plans bundle the visit + cleaning at 15 percent off the standalone cleaning rate. Multi-year plans (3 or 5 year prepay) lock in the rate and add complementary mid-cycle phone consults if anything comes up.
Visit timing: most plan visits land in late spring after seed drop and before peak summer use. Outdoor entertaining season starts with the system cleaned, sealed, and inspected.
Common Questions
Answers before you call
How much does the maintenance plan cost?
Castle Rock annual plans run $295 to $650 per visit depending on system size. Includes cleaning at 15 percent off standalone rate, inspection, and priority repair scheduling.
Annual or biennial?
Annual if you have pine, cottonwood, or heavy tree cover within 30 feet of the deck. Biennial for homes with mostly grass and ornamental landscaping.
Do you maintain other companies’ systems?
Yes. We service aluminum, vinyl, or competitor steel underdecks installed by anyone. Same plan structure and pricing.
Do I need to be home?
No. We work from outside the deck and email a photo report when complete. You can be at work, traveling, or on the patio with coffee — we do not need access to the home interior.
What if something needs repair?
Repairs require a separate quote and your written approval. Maintenance plan customers get priority scheduling — typically 1 to 2 weeks vs 3 to 6 weeks for non-plan customers.
