Level and Solid Before Anything Goes Down
Subfloor preparation services in Spokane and Coeur d’Alene that correct unevenness, reinforce weak areas, and prepare surfaces for long-lasting flooring.
Your subfloor is what holds everything up, and if it is uneven, soft, or damaged, your new flooring will not perform the way it should. In Spokane and Coeur d’Alene, older homes often have subfloors that have settled, absorbed moisture, or developed dips over time. Stone Base Contractors LLC inspects the subfloor after old flooring is removed, identifies problem areas, and completes the repairs and leveling needed before new material is installed.
The process includes evaluation of the existing subfloor condition, reinforcement or replacement of damaged sections, and leveling to correct slopes and uneven spots. Moisture mitigation is addressed where needed, and the surface is prepped to ensure proper adhesion for glue-down systems or a stable base for floating floors. This work is required if you want your floor to stay flat, quiet, and intact for years.
If you are preparing for a flooring installation in Spokane and beyond and want to make sure the foundation is right, reach out to schedule an inspection and get a clear plan for what needs to be done.
Why the Surface Under Your Floor Matters
Subfloor preparation starts with a visual and physical inspection of the exposed surface. In Spokane area homes, plywood and OSB subfloors are common, and both can develop issues from water exposure, structural settling, or improper installation. You might notice soft spots near bathrooms, dips in hallways, or squeaks that suggest loose fasteners. These issues are identified during the walkthrough and addressed before new flooring is laid.
After repairs are made, you will notice the floor feels stable underfoot and looks level across the room. High spots are sanded down, low areas are filled with leveling compound, and damaged sections are replaced or reinforced. The surface is then cleaned and prepped so adhesives bond correctly and floating systems do not shift or gap over time.
If moisture is present, a vapor barrier or moisture mitigation product may be applied depending on the flooring type being installed. The goal is to create a dry, flat, and structurally sound base that meets manufacturer requirements and supports the warranty on your new floor. Without this step, even high-quality flooring can fail early.
Homeowners often ask what subfloor prep includes, how long it takes, and whether it is always necessary. Here are the answers to the most common questions that come up during planning.
Let's talk through what this step involves
What does subfloor preparation include?
It includes inspection, repair or replacement of damaged sections, leveling of uneven areas, moisture mitigation, and surface prep for adhesion. The scope depends on what the inspection reveals.
How do you know if a subfloor needs leveling?
A straightedge or laser level is used to check for dips and slopes. Most flooring manufacturers require the subfloor to be flat within one-eighth inch over ten feet, and leveling compound is applied where needed to meet that standard.
When is subfloor replacement necessary?
Replacement is needed when sections are water-damaged, rotted, or too weak to support new flooring. You might notice soft spots, visible staining, or a spongy feel when walking on the exposed subfloor.
Can subfloor prep be done without replacing the entire floor?
Yes, most jobs involve repairing or reinforcing only the damaged areas. Full replacement is rare and usually only required after significant water damage or structural issues.
How long does subfloor preparation take?
Most residential jobs take one to three days depending on the size of the area and the extent of the repairs. Leveling compound typically needs 24 hours to cure before flooring installation can begin.
