Installing wide plank hardwood flooring transforms any GTA home with a clean, modern look that narrower boards simply cannot match. Whether you're a homeowner taking on a DIY project or weighing professional installation, understanding the complete process from acclimation to finishing details makes the difference between a floor that performs beautifully and one that creates problems down the road. This guide covers every step GTA homeowners and contractors need to know about how to install wide plank hardwood flooring properly.
Preparing Your Space for Wide Plank Hardwood Installation

Proper preparation determines whether your wide plank floor stays flat and gap-free for decades or develops problems within months. The first critical step is acclimation. Hardwood planks must adjust to your home's temperature and humidity before installation. Keep all planks sealed in their original packaging and store them flat in the installation area for 48 to 72 hours. During GTA winters, extend this period to five to seven days when humidity fluctuates significantly between heated storage facilities and interior spaces.
Inspect the subfloor before any material arrives. For concrete slabs, check that the surface varies no more than 3 mm over a 3-metre span using a long straightedge. Wood subfloors require secure fastening with no squeaking or movement. Address any raised nails, protruding screws, or damaged sections before proceeding.
Gather essential tools ahead of time:
- Pneumatic flooring nailer or stapler
- Fine-tooth saw for cutting planks
- Spacers for expansion gaps
- Tape measure
- Moisture meter for subfloor testing
Skipping subfloor preparation or tool gathering leads to delays and compromised results once installation begins.
Selecting the Right Underlayment for Wide Plank Flooring
Underlayment supports the floor above and directly affects how well wide planks handle moisture and temperature changes. Wide boards—typically those 5 inches or wider—expand and contract more noticeably than narrower options, making the underlayment choice even more important.
Match the underlayment to your subfloor type:
| Subfloor | Recommended Underlayment | Key Features |
|---|---|---|
| Wood/Plywood | Foam or cork | Basic cushion and minor subfloor correction |
| Concrete | Rubber or modified bitumen with moisture barrier | Prevents vapour transmission that damages wood |
| Condo/Multi-level | Sound-dampening with IIC rating compliance | Meets Strata acoustic requirements |
For GTA condominiums, many Strata corporations specify minimum impact insulation ratings. Confirm requirements with your property manager before ordering materials. The right underlayment with built-in moisture protection reduces expansion and contraction issues that cause gapping, cupping, or buckling in wide plank installations.

Step-by-Step Installation Methods for Wide Plank Boards

Wide plank hardwood typically uses nail-down or staple-down installation over wood subfloors. Glue-down works for concrete slabs when using an appropriate adhesive. Floating installation is not recommended for solid hardwood.
Nail-Down Installation
- Set the first row with fasteners placed every 10 to 12 cm along the tongue edge using a pneumatic flooring nailer loaded with 2-inch cleat nails.
- Maintain expansion gaps of 12 to 15 mm around all walls and fixed objects including kitchen islands, bathroom fixtures, and stair stringers. Use spacers to ensure consistent spacing throughout the installation.
- Stagger end joints by at least 20 cm between adjacent rows. Avoid creating H-joints—those repetitive joint patterns where two joints align across consecutive rows—by keeping offsets random across the entire floor.
- Check alignment regularly as you work. Wide planks amplify minor deviations that narrower boards hide.
Transition Strips
Where hardwood meets different flooring materials, install appropriate transition strips. T-mouldings work for equal-height surfaces; reducers bridge height differences between hardwood and lower vinyl or tile surfaces. Always follow manufacturer guidelines for the specific transition product chosen.

Common Installation Pitfalls and How to Avoid Them
Three mistakes cause most wide plank hardwood problems in GTA homes:
Skipping Acclimation Cutting corners on acclimation saves no real time. Without proper adjustment to interior conditions, boards contract after installation, creating gaps. Alternatively, they expand and buckle or cup. The 48-to-72-hour minimum exists for good reason.
Neglecting Moisture Testing Concrete subfloors especially require moisture testing before installation. High moisture levels cause adhesive failure, board movement, and can void manufacturer warranties. Use a calcium chloride test or relative humidity probe. Confirm acceptable levels with the flooring manufacturer.
Ignoring Subfloor Levelness Wide planks flex more noticeably than narrower boards when the subfloor beneath is uneven. The 3 mm variation tolerance over 3 metres is not negotiable for wide plank performance. Use self-levelling compound on concrete or shim and fasten wood subfloors properly before installation begins.

Professional Installation Costs and DIY Considerations in the GTA
Professional installation for wide plank hardwood in the Greater Toronto Area typically ranges from $4 to $8 per square foot, varying by project complexity, accessibility, and contractor availability. This rate generally covers labour for nail-down or staple-down installation over prepared subfloors.
DIY installation saves labour costs but requires:
- Rental of a pneumatic flooring nailer or stapler
- Purchase of appropriate fasteners and adhesives
- Familiarity with GTA building code requirements for floor preparation
- Confidence in measuring, cutting, and fitting planks around obstacles
- Understanding of expansion gap requirements and moisture management
A hybrid approach works well for many GTA homeowners: hire professionals for acclimation guidance, subfloor preparation, and tricky transitions, then complete straightforward row installation yourself. This balances cost savings with expert handling of the most critical details.

Frequently Asked Questions About Wide Plank Hardwood Installation
How long should hardwood acclimate before installation in Canadian climates? A minimum of 48 to 72 hours applies in warmer months. During GTA winters when interior humidity fluctuates significantly between heated storage and occupied homes, extend acclimation to five to seven days. Solid hardwood is sensitive to moisture changes, and adequate acclimation prevents expansion, contraction, and gapping after installation.
Can wide plank hardwood be installed over radiant heating systems? Yes, but confirm compatibility with the flooring manufacturer first. Radiant-heat-appropriate underlayments are required, and operating temperature limits typically cap at 27°C maximum. Engineered hardwood often performs better over radiant heat than solid hardwood because the layered construction handles thermal cycling more gracefully.
What causes squeaking after installation and how can it be prevented? Squeaking results from movement between boards or between flooring and subfloor. Prevent it by ensuring fasteners penetrate solid subfloor properly, maintaining consistent indoor humidity between 35% and 55% relative humidity, and using construction adhesive on tongue-and-groove joints where recommended by the manufacturer.
Is wide plank hardwood suitable for GTA condominiums? Solid wide plank hardwood requires nail-down or staple-down installation, which involves noise during installation and may not be permitted in some condo buildings. Condo acoustic requirements often necessitate sound-dampening underlayments. Engineered hardwood or SPC vinyl may be better choices for condo installations—confirm requirements with your property manager before ordering.
What subfloor is required for wide plank solid hardwood? Solid hardwood must be installed over wood subfloors (plylywood, OSB, or existing wood planks) using nail-down or staple-down methods. It can also be glue-down over properly prepared concrete. Solid hardwood is not suitable for floating installation and should not be installed directly over concrete without an appropriate adhesive system.
Can I install wide plank hardwood myself? DIY installation is possible if you have experience with home improvement projects, access to the right tools including a flooring nailer or stapler, and understanding of acclimation, expansion gap, and moisture management requirements. Mistakes with wide plank hardwood are more visible than with narrower boards and can be costly to repair.
How does wide plank flooring affect room appearance? Wide planks create a cleaner visual flow with fewer seams, making rooms appear more spacious and contemporary. They also showcase natural wood grain and character more prominently, which some homeowners prefer while others favour the traditional look of narrower strips.
What is the cost of wide plank hardwood flooring in the GTA? Material costs vary by species, grade, and brand. Canadian-made solid hardwood from premium collections typically ranges from approximately $5 to $6 per square foot and up, depending on species and grade. Installation labour adds $4 to $8 per square foot. Always confirm current pricing on the product page or by contacting the supplier directly.
