Getting an accurate online interlock quote in Ottawa starts with providing the right information. While nothing beats an in-person site visit, today’s technology allows you to get a reliable preliminary estimate from the comfort of your home. The key? Quality photos and precise measurements.
At Interlock Experts, we’ve refined our online quoting process to provide Ottawa homeowners with estimates that are typically within ±15% of the final project cost. Here’s everything you need to know about preparing for your online interlock quote.
Why Measurement Accuracy Matters for Your Online Quote
Interlock paving is priced primarily by square footage, with additional factors like edging, base preparation, and pattern complexity affecting the final cost. Even a small measurement error can lead to significant price discrepancies.
When measuring your project area, use a proper tape measure—not steps or estimates. Measure multiple points to account for irregular shapes, and don’t forget to include areas for steps, slopes, and transitions. A rough sketch of your layout helps contractors visualize the scope and identify potential challenges.
The 7 Essential Photos for an Accurate Online Interlock Quote
1. Overview Photo: Capture the Full Project Area
Start with a wide-angle shot that shows the entire space you want paved. Stand back far enough to capture the full area in one frame. This helps contractors understand the overall scope and context of your project.
2. Overhead Angle: The Bird’s Eye View
If possible, take a photo from an elevated position—a second-story window, deck, or even a ladder (safely!). This overhead perspective reveals the true shape of the area and helps identify drainage patterns that might not be visible from ground level.
3. Corner and Edge Details
Take close-up shots of each corner and edge where the interlock will meet other surfaces. These transition points often require special cutting and edging work that affects pricing. Capture how your project area connects to the house foundation, garage, lawn, or existing hardscaping.
4. Problem Areas: Water Pooling and Damage
Document any existing issues. If you have water pooling after rain, photograph those areas. If there’s damage to current paving, cracks in concrete, or settled areas, capture these clearly. Ottawa’s freeze-thaw cycles can create unique drainage challenges that contractors need to see.
5. Adjacent Features and Surroundings
Photograph nearby trees, garden beds, downspouts, utility boxes, and any other features within 10 feet of the project area. These elements can affect access, drainage design, and installation complexity.
6. Clear Daylight Photos Only
Take all photos during daylight hours, preferably mid-morning or mid-afternoon when shadows are minimal. Avoid evening or cloudy photos where details are hard to see. Natural light reveals surface conditions, slopes, and existing drainage patterns that artificial lighting might hide.
7. Scale Reference: Add a Known Object
Include an object of known size in at least one photo—a measuring tape, ruler, or even a standard door (36 inches wide). This helps contractors verify your measurements and estimate material quantities accurately.
Critical Information to Include with Your Online Quote Request
Current Surface Type
Specify what’s there now: grass, gravel, concrete, asphalt, or existing interlock pavers. Each surface type requires different removal and base preparation work. Concrete removal costs significantly more than removing sod, which affects your overall project budget.
Neighborhood and Location Details
Your Ottawa neighborhood matters. Projects in older areas like The Glebe or Centretown often have narrower driveways and limited equipment access. Suburban areas like Kanata or Barrhaven typically allow easier material delivery and machinery access. Mention your specific neighborhood to help contractors plan logistics.
Desired Finish Date and Timeline
Ottawa’s interlock season runs roughly May through October, with peak demand in July and August. If you have flexibility on timing, mention it—projects scheduled during shoulder seasons (May, June, September) sometimes receive better pricing. If you need completion by a specific date, state that clearly.
Budget Range and Style Preferences
Being upfront about your budget helps contractors recommend appropriate materials and designs. Specify if you’re looking for basic functionality or premium aesthetics. Browse our project gallery and mention any styles that appeal to you—this helps contractors understand your expectations.
Soil and Drainage Information
If you know your soil type, include it. Ottawa has diverse soil conditions ranging from sandy soil near the Ottawa River to heavy clay in many suburban areas. Clay soil requires more extensive base preparation to prevent settling.
Describe any drainage issues you’ve observed: Does water pool after rain? How long does it take to drain? Where does water flow during heavy storms? Do your gutters drain toward the project area? This information is critical for designing proper slope and drainage solutions.
Accessibility Information Contractors Need to Know
Equipment access can significantly impact project cost. Note the following:
- Gate width: Can a wheelbarrow or mini-excavator reach the backyard?
- Obstacles: Are there low-hanging wires, narrow side yards, or tight corners?
- Trees and roots: Large trees near the project area may complicate excavation
- Utilities: Do you know where underground utilities run? (Call Ontario One Call before digging)
- Material delivery: Can a truck park near your property, or will materials need hand-carrying?
Limited access doesn’t make a project impossible, but it does affect labor costs and timeline.
Drainage Specifics: The Details That Matter
Proper drainage is critical for interlock longevity in Ottawa’s climate. When requesting your online quote, provide these drainage details:
- Water runoff direction: Where does water currently flow during rain?
- Pooling locations: Mark areas where water collects and stands
- Gutter downspouts: How many downspouts discharge near the project area?
- Neighboring properties: Does water run onto your property from neighbors?
- Existing drainage solutions: Are there French drains, catch basins, or sump pumps nearby?
- Slope direction: Does your property slope toward or away from the house?
Ottawa’s building codes require proper drainage away from foundations. Contractors need this information to design compliant installations that protect your home.
What to Expect: Online Quote Accuracy
With quality photos and accurate measurements, expect your online interlock quote to be within ±15% of the final project cost. This accuracy range accounts for factors that can only be confirmed during an in-person site visit:
- Exact base depth required based on soil conditions
- Underground obstacles (old foundations, buried debris, utilities)
- Precise slope calculations for drainage
- Material waste factors based on pattern complexity
- Access constraints that affect labor requirements

The Next Step After Your Online Quote
An online quote is just the beginning. Once you receive your preliminary estimate, the next step is scheduling an on-site consultation. During this visit, a contractor will:
- Verify measurements and assess site conditions firsthand
- Test soil composition and check for underground obstacles
- Confirm drainage solutions and slope requirements
- Show you physical paver samples and discuss design options
- Provide a detailed, binding quote with project timeline
- Answer all your questions about materials, process, and warranties
The site visit typically takes 30-45 minutes and should be provided free of charge by reputable Ottawa interlock contractors.
Common Mistakes to Avoid When Requesting an Online Quote
Measuring Only One Direction
Many homeowners measure length but forget width, or vice versa. Always measure both dimensions, and if the area isn’t rectangular, break it into sections and measure each part. For curved areas, estimate generously—it’s better to slightly overestimate than underestimate.
Photos Taken Too Far Away
Distant photos don’t show surface conditions, existing damage, or important details. Take wide overview shots, but also capture close-ups of problem areas, transitions, and unique features. Submit 8-12 photos rather than just 2-3.
Forgetting About Slopes and Elevation Changes
If your driveway or patio area has a slope, note this in your quote request. Measure the elevation change if possible—even a rough estimate helps. Sloped areas require additional base work and precise grading to ensure proper drainage.
Not Mentioning Existing Issues
Don’t hide problems hoping to get a lower quote. If you have settling, cracks, drainage issues, or soft spots, disclose them upfront. Contractors will discover these during installation anyway, and undisclosed issues can lead to change orders and budget overruns.
Assuming All Materials Cost the Same
Interlock pavers range from economy options at $3-4 per square foot to premium products exceeding $15 per square foot. If you have a specific material in mind, mention it. Otherwise, specify your budget range so contractors can recommend appropriate options.
