When to hire a pro

- If the subfloor is wet, moldy, or structurally soft, stop cosmetic flooring work until the substrate is fixed.
- High-impact DIY mistake — Incorrect Nailing: Use finish nails and space them about 1 inch apart, countersinking them to avoid creating a tripping hazard.
- When hiring a professional to install a threshold or transition strip, provide them with the measurements of the doorway or transition area and the type of flooring involved. Ask for a detailed quote, including the cost of materials and labor, and any additional services they may provide, such as removing old flooring or adhesive.
- Inquire about the professional's experience with similar installations and their approach to ensuring a secure and even transition. Ask to see examples of their previous work or references from satisfied customers.

DIY steps
- Turn off the power to any nearby electrical outlets or switches, and ensure the floor is clear of debris and old adhesives. Put on safety goggles and a dust mask to protect yourself from sawdust and potential allergens. Measure the width of the doorway or transition area to determine the length of transition strip needed.
- Cut the transition strip to the measured length using a hacksaw or a miter saw, if available. Sand the cut ends to smooth them out and remove any splinters. Apply a small amount of construction adhesive to the back of the transition strip, following the manufacturer's instructions.
- Place the transition strip along the doorway or transition area, ensuring it is centered and even. Use finish nails to secure the strip to the subfloor or existing flooring, spacing them about 1 inch apart. Make sure the nails are countersunk to avoid creating a tripping hazard.
- Use a level to verify the transition strip is straight and even. Check the manufacturer's instructions for any specific recommendations on securing the strip or applying additional adhesive.
- Allow the adhesive to dry completely, following the manufacturer's instructions, usually several hours or overnight. Once dry, inspect the transition strip for any gaps or unevenness and make adjustments as needed.
- Clean up any debris or excess adhesive, and dispose of any leftover materials responsibly. Inspect the transition strip again to ensure it is secure and even.
- Test the transition strip by walking on it and checking for any movement or creaking. Make any necessary adjustments to ensure a smooth transition between the two flooring surfaces.
