Construction Standards & Tolerances
The construction tolerances, quality checkpoints, and field protocols that define Forest Heart Builders' work in the field.
Measurable Standards, Not Marketing Promises
Quality in custom home construction comes down to measurable things the gap between two pieces of trim, the deflection of a joist, the squareness of a door opening, the consistency of a tile grout line. Forest Heart holds tolerances that exceed standard residential construction practice. The following pages document selected standards from our internal field manual.
The Four Phases at a Glance
| STANDARD | TOLERANCE | VERIFICATION |
|---|---|---|
| Floor flatness | 1/4 inch in 10 feet | Critical for hardwood, tile, and stone installation. Verified before subfloor sheathing. |
| Wall plumb | 1/8 inch in 8 feet | Verified at framing. Out-of-plumb walls are corrected before drywall. |
| Door opening squareness | Within 1/16 inch | Door openings are checked diagonally and shimmed to spec before drywall. |
| Trim gap tolerance | Hairline (visible gap unacceptable) | All trim joints are coped, glued, and finished to be effectively invisible. |
| Tile lippage | Less than 1/32 inch | Verified by hand and straightedge across every grout line. |
| Grout line consistency | Within 1/16 inch across run | Tile setting protocols include layout review and template verification. |
| Cabinet reveal consistency | Within 1/32 inch | Reveals around doors and drawers are scribed and adjusted on site. |
Documented Quality Checkpoints
Quality control is not a final inspection. It is a series of documented checkpoints, each with a written checklist and sign-off:
- Foundation square, level, plumb, and dimensionally verified before backfill.
- Framing plumb, square, and properly fastened before mechanical rough-in.
- Mechanical rough-in plumbing, electrical, HVAC inspected and pressure-tested where applicable.
- Insulation verified for proper installation and coverage before drywall.
- Drywall surface finish quality verified before paint.
- Pre-finish every surface inspected before final finish application.
- Pre-substantial completion comprehensive walk with the project manager.
FAQ About Our Standards
Are these standards documented in my contract?
Yes. Our standard contract references our quality standards, and your full specification book documents every specific brand, material, grade, and tolerance applicable to your project.
What happens if something is built out of tolerance?
It gets corrected. Our checkpoints exist specifically to catch issues at the stage where correction is straightforward. Catching a framing issue at framing is a half-day fix. Catching the same issue after drywall and finish is a week of rework. Discipline at every stage is what keeps the project on track.
