Spring Pool Build Calendar: When to Sign for a Summer 2026 Swim

April 29, 2026 · 5 min read · By Anderson Brothers Pools

Quick answer for spring 2026: if you sign in late April or early May, you’re realistically swimming in late July or August this summer — assuming a clean permit, no major site complications, and you don’t fight us on finish selections. Sign in May or June and we’re talking late August or pushing into September. Sign in July, you’re swimming in 2027.

This isn’t us trying to push you. It’s just how the Michigan build season works. Here’s the realistic week-by-week so you can plan around it.

Where we are right now: our 2026 build calendar still has a small number of summer-swim slots open as of late April. The bigger 2026 conversations are now mostly about fall builds (swim by Memorial Day 2027) and the early 2027 schedule.

Why the window is so tight in Michigan

The honest reason: our buildable season is roughly April through November. Frozen ground stops excavation. Cold concrete stops gunite curing properly. Snow and ice stop decking. Most years we get about 30 weeks of clean work weather, sometimes less. A custom gunite build needs 8–12 of those weeks.

That math means there are maybe 18–20 build windows we can squeeze into a calendar year, and we have multiple crews, but each project still consumes one slot somewhere on the calendar. By the time we’re into late spring, the early-summer slots are gone.

The realistic week-by-week from signed contract to first swim

Phase Typical duration What’s happening
Design finalization 1–3 weeks Final shape, depth, features, finishes, decking, mechanical equipment.
Permit submittal & approval 2–6 weeks Pool, electrical, fence/barrier permits. Township-dependent.
Crew mobilization 1 week Equipment to site, access prep, utility marking.
Excavation & rough plumbing 1–2 weeks Dig the hole, set plumbing rough-in, set forms.
Steel cage 1 week Rebar grid construction, structural inspection.
Gunite shoot & cure 1–2 weeks Shotcrete, walls and floor, 7–10 days cure.
Tile, coping, equipment-pad 2 weeks Waterline tile, coping stone, equipment installation.
Decking 1–2 weeks Concrete, pavers, or stone deck.
Plaster & water-fill 1 week Plaster shoot, immediate fill, no time to dry out.
Equipment startup & chemistry balance 1–2 weeks Pump priming, heater commissioning, water chemistry.
Final inspections & landscape restore 1 week City final, fence final, basic dirt restore.

Add it up: 11–19 weeks worst-to-best. Realistic median: 12–14 weeks. Sign April 25, swim mid-August. Sign May 10, swim early September. Sign June 1, swim late September or October. Sign July, you’re done for the season.

The variables that compress or extend that timeline

Things that COMPRESS the timeline (we work faster)

  • You’ve already done your HOA submittal — saves 1–2 weeks for many SE Michigan subdivisions.
  • You pick finishes from samples we bring to the consultation — some homeowners spend weeks deciding on tile, coping, and plaster color.
  • Your township is on the faster end (Wixom, Troy, Novi typically faster than Bloomfield Hills).
  • Standard rectangular shape — less custom shell engineering.
  • Standard equipment package — in-stock vs special-order.

Things that EXTEND the timeline

  • Custom shell features — vanishing edges, beach entries, integrated raised spas with separate engineering.
  • Specialty plaster or aggregate finishes — pebble or quartz aggregates have longer lead times than standard white plaster.
  • Imported tile or stone coping — some specialty coping materials are 6–10 week lead.
  • Pool/spa automation panels with specific configurations — sometimes back-ordered.
  • Site access constraints — cranes-over-house builds take longer than drive-in access.
  • HOA back-and-forth — some architectural-review boards meet monthly.
  • Stretches of bad weather — we don’t shoot gunite in heavy rain, don’t pour decking on frozen ground.

What you can do RIGHT NOW even before signing

Whether you sign with us or somebody else, here’s what’s worth doing immediately if you want to swim this summer:

  1. Pull your HOA architectural review packet if you’re in a subdivision that has one. Know what they require for pool submittals before any builder needs the info.
  2. Walk your yard with a tape measure. Know your setbacks (back property line, side property lines, distance from the home, septic field if applicable).
  3. Take phone pictures of access — the side gate, fence sections, anything we’d have to remove or work around.
  4. Talk to your spouse / partner about budget range before any consultation. The conversations that go fastest are the ones where the homeowners are aligned on what they want to spend.
  5. Save 5–10 inspiration photos — not as a directive, but to communicate the feel you’re after. We design from your goals, not from someone else’s pool.

What slots are still bookable for 2026

As of late April 2026:

  • Summer-swim slots (sign now, swim mid-August): a small number remain. Standard-shape gunite with a not-too-custom feature set fits these best.
  • Late-season slots (sign now, swim September or October): more availability. Useful if you want to start the season swimming in 2027.
  • Memorial Day 2027 slots (sign by late summer 2026, build September–June): these are the slots most repeat customers ask about. They give us time to do the kind of high-end backyard build that’s hard to compress into 12 weeks.

What to do next

If summer 2026 is the goal: call us this week. We’ll do the in-home consultation, talk through what’s realistic for your timeline, and tell you honestly whether we can hit it.

If 2027 is the goal: still call this week. The fall-2026 build calendar is what fills up between now and August. The earlier you start the design conversation, the better the slot we can give you.

Frequently asked questions

How long does a custom gunite pool actually take to build?

Plan on 8-12 weeks of active build time once permits are approved, plus 2-6 weeks of permit-approval time before that, plus 1-3 weeks of design finalization. Realistic median total: 12-14 weeks from signed contract to first swim.

If I sign in May, can I swim this summer?

Probably yes, but late summer. Sign in early May, expect to swim late August or early September. The earlier in spring you sign, the earlier in summer you swim.

What’s the latest I can sign and still swim in 2026?

Realistically, late May or very early June for a swim before Labor Day. Beyond that you are looking at September or October completion, which is technically swimmable in Michigan but a short window before pool-closing season.

Why does Michigan have such a short pool build season?

Frozen ground stops excavation. Cold weather stops gunite from curing properly. Snow and ice stop decking. Most years we have roughly 30 weeks of clean build weather between April and November.

Can you guarantee my pool will be done by a specific date?

We give realistic dates and we hit them when weather and inspections cooperate. We do not promise dates we cannot control (like inspector schedules or 10-day rain stretches). What we will commit to is keeping you informed weekly and being straight about anything that shifts.
