Nearby: a deck & screened porch in Overland Park
In southern Overland Park, next door to Olathe, All Under One Roof built a multi level deck & screened porch in 2018 to sealed engineering: exterior Glulam beams, double rim beams & concrete piers between 12 & 18 inches in diameter. In 2023 the firm came back to repair rot in the rim where the deck meets the house, cutting it back to sound timber & rebuilding that joint, which is where most deck rot starts.
The porch was rescreened with a heavy grade pet resistant screen held by exterior screws, so a single panel can be replaced on its own, & the sunroom floor was taken back to the slab, prepped flat & crack filled before the new floor went down. The full Overland Park deck & screened porch project shows the finished work.
Additions, basements & permits in Olathe
The City of Olathe Building Codes division issues residential permits for new homes, additions & decks. All Under One Roof prepares the drawings with the licensed AIA architect & professional engineer on staff, pulls the permit & schedules each inspection inside the contract. Room additions & basement finishing both start with a structural & moisture assessment, so the scope is priced on what the house can actually carry.
