Part of Which eco friendly flooring options suit your subfloor and household?
An eco friendly flooring checklist for every stage of the project
A flooring checklist in four stages: what to survey, which documents to demand, what to test before the slab is covered, and what to check at handover.
This eco friendly flooring checklist runs in four stages: survey, documents, pre-installation tests, and handover. Every step is built around something you can verify in writing or measure on site, rather than a claim made in a showroom.
What to take away
- Survey the subfloor before you shop. Everything downstream depends on what it turns out to be.
- Certification paperwork should be requested by name and saved as a file, not admired on a website.
- Test a basement or slab-level room for radon before you cover the floor, not after.
- Handover is a checklist too, and the expansion gaps are the thing most often missed.
Stage one: survey
- Subfloor type identified in every roomslab, joists, existing floor, or a mix
- Moisture readings taken and recorded with method, instrument and date
- Floor height at every door and threshold measured
- Existing floor material identified, and its age noted
- If the building predates 1978, testing arranged before removal begins
- Any suspect old resilient tile or mastic left undisturbed pending a professional test
The last two lines are the ones that carry consequences. Old flooring is not a category to experiment with.
Stage two: documents before ordering
Ask for and save these, as files rather than links:
- The manufacturer's installation instructions for the exact product, format and batch.
- A formaldehyde compliance statement for composite woodTSCA Title VI, plus CARB Phase 2 for products sold in California.
- The certification certificate itself, by name, not a logo on a web page.
- The product's environmental product declaration (EPD) or health product declaration (HPD).
- Moisture test results for the slab or subfloor, with method, instrument, date and the manufacturer's stated limit.
- The written warranty, including the acclimation and expansion-gap conditions it depends on.
Documents to save before ordering
- Product data sheet, exact variant, wear layer
- Formaldehyde compliance documentation
- Installation instructions, moisture thresholds, acclimation
- Adhesive, primer and underlayment data sheets
- Care and maintenance sheet, warranty voids
- Warranty document, exclusions read in full
Certification is checkable rather than notional. EPA publishes the recognized accreditation bodies under the composite wood products rule, which sit behind the certifiers whose names appear on compliance documents. If a document names nobody, it is not a compliance document.
Which certificate a product needs depends on what it is made of. Bamboo, reclaimed wood and other wood flooring live or die on their forestry paperwork. Cork and linoleum are judged on their binders, oils and finishes. Wool carpet is judged on its fiber, backing and adhesive. Ask for the certificate that matches the material, by name:
- FSC chain-of-custody certification for bamboo, reclaimed wood and other wood flooring.
- FloorScore for hard-surface flooring, including laminate and resilient planks.
- GREENGUARD Gold for low chemical emissions from flooring and the adhesives under it.
- Green Seal or Cradle to Cradle certification for adhesives, sealers, oils and finishes.
- TSCA Title VI compliance statements for composite wood cores, and CARB Phase 2 for products sold in California.
Stage three: before the floor goes down
| Check | Why now | Once covered |
|---|---|---|
| Radon test in slab and basement rooms | Sealing changes how soil gas moves | Retesting means lifting the floor |
| Moisture reading, second confirmation | Conditions change between visits | Warranty argument |
| Photographs of the bare substrate | Records what was repaired | No evidence exists |
| Underfloor heating pressure test | Leaks are found while accessible | Destructive repair |
| Acclimation confirmed by meter | Movement later depends on it | Gapping or buckling |
Radon deserves the top row. EPA's frequently asked questions about radon covers what it is, how testing works and what results mean. Since a finished basement floor is exactly the kind of work that changes airflow at ground level, testing before the work is both cheaper and more informative. Use a measurement professional certified through the AARST-NRPP program, or a test kit whose instructions you follow exactly, and read the result against EPA's action level.
Stage four: handover and the first month
Walk the floor with the installer. Check that expansion gaps exist at every perimeter and are covered rather than filled. Check thresholds for height and fixing. Look along the floor at low angle for high spots, adhesive ridges and lippage between planks or tiles.
Then log conditions. Record room temperature and humidity at handover and again at one month, so movement can be interpreted rather than argued about.
Anything unexpected is worth checking against the common flooring failures and their causes. If you are still deciding on a product, the shortlist logic sits in our guide to which floors make sense for buyers.
