EXCAVATION
From small digs to full site prep, this Q&A covers utility locating, equipment access, soil handling, safety steps, and how we keep the job clean and on schedule.
How does excavation work?
Excavation is the process of removing earth, rock, or other materials from a site to create a foundation for construction or other land development. It typically involves site surveying, marking the dig area, using heavy equipment (like excavators or backhoes), and transporting the removed material. It's used for foundations, trenches, grading, and drainage systems.
How much does excavation cost?
Excavation costs vary depending on the size of the area, soil type, depth of excavation, location access, and whether obstacles (trees, old structures, utilities) need removal. Costs typically range from $50 to $200 per cubic yard or $1,000 to $5,000+ for full projects. Additional fees may apply for hauling dirt, permits, or working in tight access areas.
Is excavation required before building a home?
Yes, excavation is usually one of the first steps in building a home. It prepares the land for the foundation, plumbing, and utility installations. Proper excavation ensures the ground is level, stable, and safe for construction, helping prevent future structural issues.
What’s the difference between excavation and landscaping?
Excavation involves large-scale earthmoving, often using heavy machinery to dig foundations, trenches, or grade land for building. Landscaping is more about shaping and beautifying the land’s surface, like adding plants, sod, or decorative features. Excavation is structural; landscaping is aesthetic.
When are permits needed for excavation?
Most cities or counties require permits for excavation, especially for large projects, digging near property lines, or disturbing public utility zones. Always check with your local building department before digging.
How long does excavation take?
Small residential projects (like digging for a driveway or foundation) may take 1–3 days. Larger or complex projects (with utility work, drainage, or grading) could take 1–2 weeks or longer. Factors like weather, soil conditions, and accessibility can affect the timeline.
How are underground utilities handled during excavation?
Before excavation starts, utility lines (gas, water, electric, internet) must be located and marked to prevent dangerous and costly damage. In the U.S., you must call 811 (the “Call Before You Dig” number) at least a few days in advance. Contractors often coordinate this step to ensure safe digging.
What happens to the dirt and debris that’s removed?
Excavated material can either be reused on-site (for grading, backfilling) or hauled away to disposal or recycling facilities. Some contractors include haul-off in their quotes, while others charge separately. It's important to clarify who handles cleanup and where the debris goes.
What kind of equipment is used in excavation?
Common excavation equipment includes:
-
Excavators (standard or mini)
-
Backhoes
-
Skid-steer loaders
-
Dump trucks
-
Bulldozers
The type used depends on the job size, depth, soil type, and site access. Residential jobs may use compact machinery for maneuverability.
​What should property owners do to prepare for excavation?
Before excavation, clear the area of personal belongings (furniture, plants, etc.) and ensure vehicles or obstructions are moved. If fencing or structures block access, you may need to remove them. It’s also smart to confirm all utilities are marked and that neighbors are informed if equipment will be near shared property lines.
DRAINAGE
Water issues demand the right fix. Here we explain French drains, dry wells, basins, downspout tie-ins, positive pitch, and how we diagnose problems to keep your yard and foundation dry.
What is yard drainage and why do I need it?
Yard drainage means managing the flow of water across your property so it doesn’t pool, saturate soil, damage landscaping, or seep into your home’s foundation. Without proper yard drainage you may see soggy spots, erosion, basement leaks or cracks in the concrete. You could also see an increase in mosquitos in the area.
What are the common signs of a poor drainage system in the yard?
-
More mosquitos then normal for your area
-
Water pooling or standing in low spots long after rain.
-
Saturated ground, especially near the house or garage.
-
Erosion of soil, plant damage or washed‑out areas.
-
Water entering the basement or crawl space.
What drainage problems occur around driveways?
Driveways often reinforce or create impermeable surfaces. Water can run toward your garage, basement or house instead of away. Low slope or improper grading causes pooling on or near the driveway, which may lead to damage or safety hazards (ice in winter, slippery surfaces).
How do gutters and downspouts fit into the drainage picture?
The roof sheds a large volume of water. If your gutters or down‑spouts are clogged, undersized or discharge too close to your house, water can overload the yard, wash toward your foundation, or pool near the house. A well‑functioning gutter/down‑spout system is the first line of defence.
How far should a down‑spout discharge be from the foundation?
Ideally the water should be carried away at least 4–6 feet (or more) from the foundation so it won’t soak into the soil immediately beside the house. Some systems extend underground to 10–20 feet.
What are typical drainage solutions for yards?
-
Grading the slope of the land so water flows away from the house or driveway.
-
Surface drains or swales: shallow channels to collect runoff.
-
Subsurface drains (e.g., French drains): buried perforated pipe surrounded by gravel/fabric.
-
Extending down‑spouts, installing down‑spout discharge lines or pop‑up emitters.
Can I fix drainage issues myself?
Yes, some fixes are DIY‑friendly: keeping gutters clean, ensuring down‑spouts carry water away, adding minor grading, clearing leaves/debris from swales or surface drains. However, if the problem is large (deep saturated soil, foundation issues, heavy runoff) you’ll likely need a specialist.
What maintenance does a drainage system require?
How much does drainage improvement cost?
Costs vary a lot depending on property size, soil type, slope, system complexity. A simple down‑spout extension may cost a few hundred dollars; a full subsurface drainage system could run into thousands.
Will fixing yard or gutter drainage add value to my home?
Yes. Proper drainage protects the home’s foundation, reduces risk of flooding or water damage, improves landscaping health and curb appeal — all of which are attractive to prospective buyers.
Why is there so many mosquitoes in my yard?
The reason there is so many mosquitoes around your property could just be from something as simple as poor drainage. Mosquitos breed in standing water, so if your drainage system is not working properly you could have pools of water around your property acting as a breeding ground for mosquitos. In that case your best bet is to talk to a Drainage professional to make sure there is no opportunity for water to pool on your property.
Why is water pooling in my yard after rain?
Water pools when the soil can't absorb rain fast enough, or when the land is improperly graded, directing water to low spots. Common causes: compacted soil, heavy clay content, poor slope, or blocked drainage paths.
How do I fix a low spot in my yard that holds water?
Fill the low spot with soil that matches your yard’s texture, and re-grade it so it slopes slightly away from your home. For frequent pooling, consider a French drain or surface drain system to redirect water.
What is the best way to redirect downspout water away from my foundation?
Extend the downspout using rigid or flexible pipe to at least 4–6 feet from your home. Bury it underground with a pop-up emitter or discharge into a swale, rain garden, or dry well.
How far should a downspout discharge be from the house?
Ideally, downspouts should discharge at least 4 to 6 feet from the foundation. In wet areas or properties with poor soil drainage, 10 to 20 feet is even better.
Why is my driveway flooding or holding water at one end?
Your driveway may be poorly graded (sloping toward your garage or house) or lack a drainage channel. Without an outlet, water collects at the lowest point, especially on flat concrete or asphalt. You could install a driveway drain system that collects the runoff at the end of your driveway and redirects the water.
How can I improve drainage around my driveway without repaving?
Install a trench drain (channel drain) across the base or edge of the driveway. You can also regrade the surrounding yard or add a catch basin to intercept runoff before it pools. You can also hire a company who specializes in yard drainage.
What is a French drain and when should I use one?
A French drain is a gravel-filled trench with a perforated pipe that collects and redirects water underground. It’s best for soggy yards, areas with slow drainage, or places where water pools consistently.
Are channel drains worth it for a driveway drainage problem?
Yes, channel drains are effective for capturing surface runoff on driveways and preventing water from reaching your garage or foundation. They're ideal for paved surfaces with low slopes.
How do I tell if the soil under my yard is preventing water absorption (clay vs. sandy soil)?
Do a simple soak test: dig a 12" hole, fill it with water, and time how long it drains. If it takes several hours or doesn’t drain at all, you likely have heavy clay soil, which resists water infiltration.
When do I need a permit for installing drainage systems on my property?
Permits may be required if you're altering land grading, installing systems near property lines, or discharging water into public storm systems. Check with your local building department or HOA.
How do I maintain or clear subsurface drainage (like a French drain) once installed?
French drains require minimal maintenance but should be checked yearly. Clear leaves or debris from inlet grates or pop-up emitters. If performance declines, flushing the pipe or professional jetting may be needed.
How often should I clean or inspect my gutters and downspouts for proper drainage?
-
Inspect and clean them at least twice a year—in the spring and fall. If you have heavy tree coverage, check more often. Clogged gutters overflow and can cause water to drain toward your foundation. You can always call a company like Sure Shot Site Solutions to come out and do an inspection on your underground drainage pipes.
Can landscaping changes fix drainage problems, or do I need heavy equipment?
Light drainage issues can often be fixed with landscaping: grading, swales, or rain gardens. For deep pooling or widespread saturation, professional drainage systems or excavation may be necessary.
What are the signs my foundation is being threatened by poor yard drainage?
-
Cracks in the basement or foundation walls
-
Mold, mildew, or musty smells in the lower level
-
Water seepage or puddles inside
-
Sinking or settling near the foundation perimeter
How long does it take to fix drainage issues around a house?
Simple fixes (gutter extensions, regrading) can take a few hours to a day. Full drainage system installations (like French drains or swales) may take 2–5 days, depending on site conditions and weather.
What is the cost range for installing a drainage system in New Jersey?
-
Costs vary:
-
Downspout extensions: $200–$500
-
French drains: $2,000–$6,000+
-
Surface drains / trench systems: $1,500–$4,000
-
Grading or swales: $1,000–$3,500+
Complex jobs near foundations or requiring permits may cost more.
Does grading the yard slope really help with drainage?
Yes. Proper grading ensures water flows away from your home and doesn’t pool in low areas. A slope of at least 2% (1/4 inch per foot) away from the foundation is ideal.
Can I install drainage solutions myself or should I hire a professional?
-
You can handle simple fixes (gutter cleaning, downspout extensions, grading small areas). For French drains, trenching, or systems near foundations, it’s safer to hire a professional to avoid costly errors.
What materials work best for downspout extensions?
-
Rigid PVC pipe: Durable, good for buried lines
-
Flexible corrugated pipe: Easier to install but less durable
-
Pop-up emitters: Help release water at a safe distance underground
Choose based on terrain, aesthetics, and how far you need to move the water.
How do I prevent driveway drainage issues freezing in winter (ice buildup)?
-
Install a channel drain to move water off the surface
-
Keep gutters and downspouts clear of ice
-
Use gravel or salt alternatives to reduce slipperiness
-
Ensure water doesn’t drain onto the driveway from uphill slopes or roofs
Grading
Good grading directs water where it should go. This section explains how we set elevations, reshape slopes, add or remove soil, and deliver a smooth, ready-for-sod finish
What is grading (or re‑grading) a yard/property?
Grading means altering the slope or elevation of the ground around your home or on your property so that water runs away from structures, doesn’t pool, and the land is stable.
​How steep should the slope be away from my house?
A good rule: drop at least 2‑3 inches per 10 feet of horizontal distance away from the foundation for proper drainage. Some sources say around a 5% slope (about 6 inches over 10 feet) is ideal.
Can I do grading myself, or should I hire a professional?
It depends on scope. Small re‑grading (a few low spots) may be DIY with rake/shovel. But when major elevation changes, near foundations, or require heavy equipment and permit, you’ll want a pro.
What are “rough grading” vs. “finish grading”?
-
Rough grading: moving large amounts of soil to establish overall slope and elevation.
-
Finish grading: smoothing and preparing surface for final landscaping (sod, plants), ensuring precise slope.
What should I check or ask before hiring someone for grading?
-
Have they surveyed slope and existing grade?
-
Do they know how the grading will impact drainage and neighbouring properties?
-
Will soil compaction and erosion control be handled?
-
Are permits required?
-
What’s included (topsoil, seeding, final smooth)?
