Engineered wood flooring has become increasingly popular in recent years due to its durability, versatility, and aesthetic appeal. One common question that homeowners have when considering installing engineered wood flooring is whether it can be installed directly over existing floorboards. In this article, we will explore the feasibility of installing engineered wood flooring over existing floorboards, the considerations to keep in mind, and the steps involved in the installation process.
Understanding engineered wood flooring
Before delving into whether engineered wood flooring can be installed over existing floorboards, it is important to understand what engineered wood flooring is. Engineered wood flooring consists of multiple layers of wood veneer bonded together to form a sturdy plank. The top layer, known as the wear layer, is made of solid hardwood, while the lower layers are typically constructed from plywood or high-density fiberboard (HDF). This layered construction provides engineered wood flooring with enhanced stability and resistance to moisture, making it suitable for a variety of settings, including areas prone to high humidity levels such as basements or bathrooms.
Factors to consider before installing engineered wood over floorboards
While in some cases it is possible to install engineered wood flooring over existing floorboards, it is essential to consider a few factors before proceeding with the installation.
- Subfloor condition: The condition of the existing floorboards is crucial. They must be structurally sound, flat, and free from any significant damage, such as rot or warping. Any loose or damaged floorboards should be repaired or replaced before installation.
- Height differences: Installing engineered wood flooring over existing floorboards will increase the height of the floor. This can potentially create issues with door thresholds, transitions to other flooring types, or appliances like dishwashers. Considerations must be made to address any resulting height differences.
- Moisture levels: Moisture is the enemy of wood flooring. It is crucial to ensure that there is no moisture or excessive humidity present in the subfloor before installation. Moisture can lead to warping, cupping, or even mold growth. Moisture tests should be performed to evaluate the suitability of the subfloor.
Steps to install engineered wood flooring over existing floorboards
If you have evaluated the factors mentioned above and decided that it is appropriate to install engineered wood flooring over existing floorboards, here is a step-by-step guide to help you through the process:
- Prepare the subfloor: Ensure that the subfloor is clean, dry, and level. Remove any dirt, debris, or protruding nails that could negatively affect the installation.
- Lay the underlayment: Install an underlayment on top of the floorboards. The underlayment acts as a moisture barrier and provides additional cushioning. Ensure that the underlayment does not overlap or create any bumps or ridges.
- Acclimate the flooring: Before installation, allow the engineered wood flooring to acclimate to the room’s environmental conditions for at least 48 hours. This step helps the flooring adjust to the temperature and humidity of the room, minimizing the risk of expansion or contraction after installation.
- Begin installation: Start by laying down the first row of engineered wood flooring, ensuring a gap of approximately 1/4 inch from the walls to allow for expansion. Use a pneumatic nailer or adhesive to secure the planks to the floorboards. Follow the manufacturer’s instructions for proper installation techniques.
- Continue installation: Install subsequent rows, joining the planks together using either the click-lock or tongue-and-groove system. Cut the last plank in each row to fit if necessary, leaving a 1/4 inch gap from the wall. Stagger the end joints between rows for stability and an aesthetically pleasing look.
- Finishing touches: Trim the excess underlayment and install baseboards or quarter-round molding to cover the expansion gap. Transition pieces may be required at doorways or areas with different flooring types.
Professional advice and assistance
While the installation of engineered wood flooring over existing floorboards is possible for certain cases, it is always advisable to consult with professionals or flooring experts to assess the suitability of your specific situation. They can provide guidance, recommend the appropriate installation method, and address any potential challenges or concerns.
Installing engineered wood flooring over existing floorboards can be a viable option under the right circumstances. Considering factors such as the condition of the subfloor, height differences, and moisture levels is crucial before proceeding with the installation. Following the proper steps, including subfloor preparation, acclimatization of the flooring, and precise installation techniques, will help ensure a successful and long-lasting installation.
