Client Experience
“We have a covered concrete slab off the back of our house that we never used because the mosquitoes out here are absolutely brutal from May through October. i30 Builders converted it to a screened porch in about a week and a half. I asked specifically about pet-resistant screens because our lab destroys everything, and they knew exactly what I was talking about — showed me the 20x20 mesh rating. My husband was skeptical about the cost but now he's out there every evening. Worth every penny.”
