Full fiberglass pool install phase-by-phase timeline for San Antonio
| Phase | Duration | What happens |
|---|---|---|
| Phase 1 | Design + shell selection + permit 1-3 weeks | Select from 40+ factory shell shapes, order shell from manufacturer, submit permit. Shell delivery lead time typically 2-4 weeks — parallel with permit process. |
| Phase 2 | Excavation + haul-off 2-3 days | Precise dig to shell dimensions. Wrong dig means shell rework. |
| Phase 3 | Shell delivery + set 1-2 days | Truck delivery, crane set into hole. Verify road access + crane setback before design. |
| Phase 4 | Backfill + plumbing hookup 2-4 days | Structured backfill (not just dirt), skimmer + return plumbing connections, fill start. |
| Phase 5 | Deck construction 5-10 days | Same as gunite — sub-base, forms, pour or set. |
| Phase 6 | Equipment + electrical + start-up 3-4 days | Same equipment install as gunite. Chemistry startup is simpler (no 28-day plaster cure). |
What extends the timeline in San Antonio
Weather: Weather delays shorter than gunite because no shotcrete cure to protect. 1-3 days per rain event during excavation or deck pour. San Antonio is a South Texas city with a long swim season and strong family-pool demand, and this climate profile means the primary weather risk here is aligned with the local season.
Permits: Same permit process as gunite — but shell manufacturing runs parallel, so permit doesn't extend the critical path unless it exceeds shell lead time. WETYR-network project managers have pre-application relationships with San Antonio-area municipalities to reduce this to the minimum feasible for your jurisdiction.
Site conditions: Rocky soil (adds 1-3 days per phase), high water table (adds engineering + dewatering), utility conflicts (adds redesign time), or restrictive access (adds crane vs backhoe scheduling).
Change orders: Every owner-initiated change order adds time. WETYR fixed-price contracts limit change orders to owner-directed scope changes only — never contractor errors.
How WETYR keeps the schedule
Every WETYR-network project publishes a Gantt schedule at contract signature. Weekly progress photo + status update. Milestone gates locked to inspection dates, not "when the crew gets to it." Weather buffers built in (typically 15% of total duration). Backup crews on standby for critical phases (shotcrete, plaster) so a single weather event doesn't cascade the entire schedule. Result: 92% of WETYR-network projects hit contracted milestones inside 5 business days.
What you as the owner control
Three things you can do to keep the schedule tight: (1) Sign your HOA architectural review app the day it's ready — HOA delays are the #1 owner-side schedule killer. (2) Return material selection sheets (tile, coping, deck material, finish color) within 5 business days — every day of delay pushes the whole schedule. (3) Do not visit the site during active construction hours — every unscheduled owner visit steals 30-60 minutes of crew productivity. Ask for weekly walkthrough windows instead.
Fiberglass Pool Install timeline FAQ for San Antonio
Can you build faster than 4 weeks?
Only for simplified scopes. New-build gunite cannot compress the 28-day shotcrete cure — that's chemistry, not scheduling. Fiberglass and cold plunge can go faster with expedited scheduling but usually at 15-25% price premium.
What happens if you miss a milestone?
WETYR credit: 1% off contract total per week of milestone slippage beyond the 5-business-day tolerance, up to 5% max. This is in the contract — not a courtesy.
Can I use the pool the day it's filled?
Yes, once startup chemistry is balanced (typically 24-72 hours after fill).
When's the best time to start a San Antonio build?
For year-round warm-weather markets, any month works. Start Sept-Nov to be swimming by spring.
