Both Lambert and Granuzzo sell Viking Pools products. Founded in Northern California, Viking opened in 1975 with a single mold. Today, it makes over 40 designs that come with a lifetime structural defect warranty.
Granuzzo says Viking’s production standards are the No. 1 benefit, especially compared to concrete.
“Concrete pools are very much dependent on the quality of the concrete – how old it was, how wet it was, how dry it was,” Granuzzo says. “Shooting it is an art form, and it’s only as good as the man with the gun. It can be hit and miss, while fiberglass is consistent and guaranteed for life.”
Out of over 2,000 fiberglass pools Lambert has installed, he says less than a half-dozen required resurfacing.

“It has limited places to leak, no liner to replace and there’s no re-plastering job,” he says.
Because fiberglass pools come ready to insert, Granuzzo and Lambert say installation usually only takes around three weeks, compared to four to five weeks for vinyl and a couple months for concrete.
Fiberglass pools also need fewer chemicals than concrete because the nonporous surface keeps the pH balanced and prevents algae. Alkaline-based concrete requires additional acid and sanitizer to achieve the same results. Granuzzo and Lambert also say the fiberglass shell has significantly better temperature retention and energy efficiency.
Concrete’s primary asset is that it’s not limited by size or design, but with fiberglass’ increased selection, homeowners have more choices than ever. Viking’s inventory offers seven different shapes, including the HydroZone, which has jets designed for cross training and physical therapy.
Vinyl-liner pools consist of steel or polymer walls and a cement floor, all covered by the lining. While they’re the cheapest in-ground option, the liner can puncture, tear or wrinkle. The liner typically requires replacement every 5 to 10 years at a cost of up to $5,000, according to CostHelper.
