Pool Design & Build
Custom concrete gunite pools with spas, water features, and modern coping.
Materials
What we install vs. what corner-cutters use.
Shell
Gunite over engineered rebar cage.
Fiberglass drop-in or vinyl liner.
Why it matters: Gunite lasts 50+ years; liners fail in 8–12.
Pump
Pentair IntelliFlo variable-speed.
Single-speed 2 HP pump.
Why it matters: Variable-speed pumps sip energy.
Sanitizer
Salt chlorine generator.
Manual chlorine dosing.
Why it matters: Salt is easier on skin, hair, and clothes and simpler long-term.
Process
A predictable path — with real durations.

Why us
Why homeowners pick Modern Builders for pool design & build.
Every pool we build has a structural engineer's stamp on the shell design — Houston expansive clay demands specific rebar patterns and shell thickness. We build to that spec, not to a shortcut. Plumbing is oversized (2.5" returns instead of the 2" that's technically enough) so the pump runs at low speed and low energy for decades. Variable-speed pumps cut pool energy use vs single-speed. Every pool we build gets one — even the smallest builds.
FAQs
Answers before you ask.
Concrete/gunite vs fiberglass?+
Gunite for custom shape, longevity, and unlimited features. Fiberglass is faster to install but limits shape and lasts less than half as long.
Do you handle permits and inspections?+
Yes — city, county, and HOA. All included.
What ongoing maintenance is required?+
Weekly skim/brush, monthly chemistry check, pump service every 5 years, resurface every 12–15 years.
Can I add a hot tub later?+
We recommend building spa-integrated from the start — much simpler than retrofitting.
