How Long Does It Take to Build an Inground Pool in Montgomery County? Your Questions Answered.

03/14/2026

Planning to build an inground pool in Montgomery County and not sure what to expect? You’re not alone. This is one of the most common conversations we have with homeowners before a project begins. Below, we’ve answered the questions we hear most often so you can plan with confidence.

FAQ #1 — How long does it take to build an inground pool from start to finish?

The full process, from your first design consultation to the day you swim, typically takes 12 to 22 weeks. That breaks down into a few distinct phases: design, permitting, construction, and finishing work.

Construction alone runs eight to twelve weeks for fiberglass pools and ten to sixteen weeks for gunite. Permitting in Montgomery County adds another two to six weeks before the build begins. Starting your planning early gives you the best chance of swimming by summer.

FAQ #2 — Does the type of pool affect how long construction takes?

Yes, significantly. Fiberglass pools are faster to install because the shell comes pre-manufactured. Once excavation is done, the shell goes in quickly and construction moves forward fast. A fiberglass pool can be in the ground in a matter of days after digging begins.

Gunite pools take longer because they are built entirely on-site. Rebar framing, gunite application, and curing all require additional time. The tradeoff is more design flexibility. Gunite allows for nearly any shape, size, or depth. For custom builds with complex features, gunite is often the better choice.

If you’re comparing options, talk to a pool contractor who builds both. They can help you decide which is right for your yard and your timeline.

FAQ #3 — How long does the permit process take in Montgomery County?

Plan for two to six weeks. Montgomery County municipalities each have their own permitting process. Some townships move faster than others. Your contractor should handle the permit applications and follow-up on your behalf.

The most important thing homeowners can do is start early. Spring is the busiest time for permit offices. If you wait until March or April to start, you may find yourself behind others who planned ahead. Fall and winter are actually great times to get your permits in motion.

FAQ #4 — When is the best time of year to start building a pool?

Late summer through early fall is the sweet spot. Starting your project in August, September, or October gives you time to get through design and permitting before winter. When spring arrives, your project can move straight into construction and you’ll be ready to swim by June or July.

Many homeowners don’t realize you can build pools through the fall and even into winter in this region, depending on weather. Getting ahead of the spring rush almost always results in a faster, smoother project.

H2: FAQ #5 — What can delay a pool build in Montgomery County?

A few things commonly add time to a project:

Weather. Rain, frost, and extreme temperatures can slow excavation and outdoor work. This is most common in the fall and early spring.

Permit delays. Some townships take longer than expected to process applications. An experienced contractor anticipates this and submits early.

Change orders. Making significant design changes mid-construction adds time. The more decisions you make upfront, the smoother things go.

Homeowner availability. Inspections and walkthroughs require your sign-off at certain stages. Being responsive and available helps keep the project on schedule.

A well-run contractor minimizes all of these. At KS Pools, we coordinate every phase closely and keep homeowners informed throughout.

FAQ #6 — Does adding outdoor living features extend the timeline?

It can add a couple of weeks, but the results are worth it. Adding a patio, pergola, outdoor kitchen, or landscaping as part of the project is actually more efficient than doing it separately later.

When everything is built together, the crews coordinate and the work flows in sequence. Doing it piecemeal means scheduling contractors separately, tearing up finished work, and spending more overall. If you’re thinking about outdoor living features, build it into your plan from the start.

FAQ #7 — What happens after construction is done?

Once the pool is finished, a township inspector reviews the work to confirm it meets local code. After passing inspection, your contractor walks you through the startup process. That includes filling the pool, balancing water chemistry, and testing all equipment.

You should also receive a full orientation on how to operate and maintain your pool. Good contractors make sure you leave that conversation confident and informed.
