Evidence
Grupo Trejos evidence
Photos documenting patterns of negligence in Grupo Trejos projects: unfinished work, leaks, electrical installations, and poor finishes. Material is presented in general terms, without identifying specific homes.
Documented visual evidence
Each image summarizes a type of problem observed on sites reported by affected families.
Door frames without supervision
Poorly cut openings in the frame, strike plates badly installed, and damaged laminate around them; careless work with no oversight.
Careless exterior finishing detail
Tiles cut and glued carelessly around the frame, with poorly applied sealant and an unfinished concrete base.
Poorly made stairs
The steps were too narrow to fit a foot, so they had to be redone.
Exposed rebar in a poorly plastered wall
Reinforcing bar left exposed next to uneven, poorly finished plaster.
Support beam with defective concrete
One of the beams that hold up the house was left with badly placed concrete and exposed rebar.
Floors with ungrouted joints
Tile joints left without grout or poorly filled, with open gaps and debris accumulated.
New floor damaged by carelessness
Newly installed floor scratched and stained, with drag marks and debris; it was not protected during construction.
Rain leaks from the ceiling
Poorly built roofs that let rain leak through.
Poorly made finishes
Gap in the floor next to the door frame.
Roofs made with different materials
You can tell these are leftover materials from other projects.
Crude, careless finishes
A complete lack of attention to detail. How can anyone deliver something like this?
Roofs made with leftover materials
On top of that, they were poorly installed.
Poorly finished ceiling and walls
Cracks in the walls and electrical wiring without conduit.
Poorly plastered wall with exposed rebar
Uneven plaster and reinforcing bars left exposed in the wall.
Deficient plaster with rebar showing
Another wall section with badly finished plaster and uncovered reinforcing bars.
Poorly plastered wall with exposed water pipe
Uneven plaster and a drinking-water pipe left exposed on the wall.
Poorly laid blocks and unfinished column top
Misaligned blocks and a badly finished column top.
Roof made from recycled pieces
Roof assembled with sheets of different color and material, apparently leftovers from other projects.
Wall leaks
Moisture stains running down from the ceiling.
Water leak from the ceiling
Water stains running down from a hole in the ceiling, with open electrical cuts left unsealed.
Poorly made door frames
The length of the door frames was not measured correctly.
Crack in finish
The house hasn't even been delivered yet and there are cracks.
Cracked countertop
Countertop corner cracked along the edge, with sealant applied unevenly against the wall.
Poorly finished floor
Careless, unfinished flooring.
Wall broken open for forgotten piping
They forgot to run the piping inside the wall, so it had to be broken open, the pipe added, and that section rebuilt.
Poor frame fastening
Splintered wood and a poorly placed screw at the joint between frame and floor.
Unfinished joints
Gaps and debris between floor, baseboard, and panel; uneven finish at the corner.
Disorganized electrical panel
Loose, tangled cables outside the breaker box.
Incomplete exterior finishes
Moisture at the base of the wall, crumbling concrete, and loose piping at the exterior corner.
Incomplete structure
Rusted rebar and porous concrete exposed at a wall corner.
Unfinished frame
Exposed concrete edge next to a door left unprotected on site.
Poorly installed baseboards
The baseboards were not even measured correctly.
Unfinished corner
Unpainted filler patch and missing or poorly cut baseboard.
Damaged laminate edge
Top layer peeled away with exposed substrate on cabinetry or a door.
Frame with paint stains
Wooden door frame with white paint stains and a careless finish.
What this evidence shows
Grupo Trejos, the construction company led by architect Luis Diego Trejos (CFIA license A-33587), has been linked to housing projects in Costa Rica where families report unfinished work, poor workmanship, and broken promises. The photos on this page document those problems in general terms.
The photos cover different construction stages —from structural work to finishes and installations— and show problems such as misaligned or poorly plastered walls, exposed reinforcing rebar, gaps in wall joints, badly finished columns and beams, leaks, deficient installations, and abandoned projects. More images will be added as we receive new material.
These patterns —lack of supervision, unskilled labor, and deficient finishes— repeat across different projects. The goal of this evidence is to let anyone considering hiring Grupo Trejos or Luis Diego Trejos review the kind of work documented here before making a decision.
