Are you planning a wood floor installation in your Mississauga, Ontario home? Then you likely already know that hardwood flooring is a long-term investment. But achieving long-lasting, beautiful results goes beyond choosing the right wood.
Although hardwood is an attractive and durable flooring option, it can suffer wear and tear when exposed to extreme climate conditions or regular foot traffic. That’s why you need to care for your hardwood floors both before and after they are installed.
Whether you are installing hardwood floors for the first time, refinishing them, or looking to extend your existing floor’s lifespan, this blog covers everything you need to know.

How to Prepare Your Subfloor for a Hardwood Installation
The subfloor is the foundation of your hardwood flooring. A weak, uneven, damp, or dirty subfloor can cause issues like warping, squeaking, premature wear, and damage. Let’s learn how to prepare yours properly when installing hardwood floors.
Step 1: Recognize the Type of Subfloor
It is important to identify your subfloor type before preparing to install a new floor. These may include concrete, plywood, vinyl, tile, or old hardwood. Each subfloor type needs a slightly different preparation method in Mississauga, where climate conditions can vary significantly across seasons, from hot and humid summers to cold and dry winters.
Step 2: Examine the Condition of the Existing Subfloor
Moisture is one of the biggest enemies of hardwood flooring. That’s why it is crucial to check the existing moisture level around your subfloor to determine whether you need to replace it before installing wood flooring in your Mississauga home.
- If you have a plywood, vinyl, or tile subfloor, use a moisture meter to check its moisture level.
- For a concrete subfloor, perform a calcium chloride or relative humidity test. You can also get help from a professional floor installer for accurate results. The calcium chloride test measures moisture at the floor surface, whereas a relative humidity test reveals the moisture conditions within the flooring slabs. If your concrete subfloor’s moisture level is too high, then install a moisture barrier. You also need to fix leaks and drainage issues and allow adequate drying time.
Step 3: Building a Solid Foundation of Even and Durable Subfloor
An even subfloor ensures hassle-free, accurate hardwood flooring installation. In order to fix uneven areas, sand down high spots. Use a cement, gypsum, epoxy, or polyurethane-based self-levelling compound to fill low areas and secure loose panels or boards as needed.
Step 4: Repair Structural Weaknesses
Before installing wood floor in your Mississauga home, check for loose or squeaky panels, rot or mould, cracks, and damaged sections in subfloor, especially in older homes. Tighten the loose areas with screws.
For sections with significant damage, remove the old hardwood flooring and baseboards with a pry bar and hammer. This also creates an expansion gap and keeping this gap is important when installing hardwood, as it tends to expand with moisture and heat.
Step 5: Clean the Glue and Dirt Residue
After repairing these structural weaknesses, remove any leftover glue, dirt, debris, nails, and staples from the old flooring, then thoroughly vacuum the space. Make sure the subfloor is completely dry after cleaning as this improves adhesion and ensures a smooth installation.
Step 6: Install Underlayment
Underlayment plays a significant role in moisture resistance, sound reduction, and increasing comfort, ultimately extending the life of your floors.
For a concrete subfloor, polyethylene foam underlayment is an effective choice, while rubber underlayment offers effective sound absorption.
Step 7: Allow Your Hardwood Flooring to Adjust
Hardwood flooring needs time to adjust to your home’s humidity and temperature levels. To do that, store the unopened boxes in the new flooring installation area of your Mississauga home for a few days or as instructed by the manufacturer. Maintain normal living conditions during the acclimation period. Following this step helps to prevent excessive contraction or expansion of the hardwood planks after installation.
Essential Care Tips to Protect Your Hardwood Floors and Prolong Their Life
Below are some expert tips to help you protect the hardwood floors in your Mississauga home:
Gentle and Regular Cleaning
With gentle, regular cleaning, you can keep your hardwood floors looking like new for years. Don’t use excess water when mopping, as it can seep into the wood, cause warping, and damage the floor’s surface. Instead, use a soft-bristled broom or vacuum on a hardwood setting to sweep away dirt and debris, which would otherwise scratch the finish.
If your floor is exposed to mud, snow, or rainwater, remember to clean it promptly. Otherwise, moisture and dirt buildup can ruin the finish and compromise your floor's quality.
Controlling Indoor Humidity
Hardwood naturally interacts with humidity, which can cause it to expand. That’s why it is important to maintain a consistent humidity level in your home year-round. Using a humidifier during winter can protect the wood from losing its natural moisture, and a dehumidifier in summer can help reduce excess moisture.
Using Furniture Pads
Dragging or sliding furniture across your floor can cause scratches and dents due to its friction and weight. To prevent this, place felt pads under your furniture’s legs. This simple precaution can keep your floor free from the wear and tear of daily furniture use.
Placing Rugs in High-Traffic Areas
Thoughtfully placing area rugs or runners in high-traffic areas of your home, like hallways, living rooms, and entryways, is one of the most effective ways to protect your flooring, as they absorb some of the impacts of foot traffic.
Also, make sure the rugs and runners you placed are breathable. Otherwise, they can trap moisture beneath them, which can damage the wood.
Subfloor preparation is extremely important for installing a wood floor. Inspect, repair, level, and clean your subfloor thoroughly to ensure a strong, durable base for a precise hardwood floor installation in your Mississauga home. By using a soft-bristled broom or vacuum, controlling indoor humidity, using furniture pads, and placing rugs in high-traffic areas, you can prolong your flooring’s lifespan.
