H&J Landscaping — Concrete, Pavers, Artificial Grass

PLANNING BASICS

What belongs in a project estimate?

Look beyond the finish and understand what the proposed work includes, so you can compare bids fairly and sign with confidence.

Written by the H&J Landscaping crew. Updated September 2026.

Two estimates for the same yard can look completely different, and not just in price. One might be a single line with a total. Another might run two pages. The difference usually tells you more about the work than the number at the bottom does.

A good estimate describes what will actually be built, including the parts you will never see once the job is done. This guide explains what should be in one, what to watch for, and how an estimate becomes a contract.

Look beyond the finish

Most people read an estimate for the visible part: the paver color, the stamp pattern, the turf. But how long a surface lasts is decided mostly underground, by the demolition, the base and the drainage. If those lines are vague or missing, the price is not really comparable to a bid that spells them out.

What a complete estimate should include

Scope and measurements

Each area listed separately, with its approximate square footage or linear feet: the driveway, the patio, the side path, the wall. A drawing or marked-up photo helps a lot.

Demolition and haul-off

What is being removed, such as old concrete, lawn, roots or planters, and whether disposal is included. Removing thick or reinforced concrete costs more, so it should be stated.

Excavation, grading and base

How deep the area is dug, what base material goes in, how thick it is once compacted, and whether geotextile fabric is included. This is the line most responsible for price differences between bids.

The surface itself

  • Concrete: slab thickness, reinforcement (fiber, wire mesh or rebar), finish, color, control joint spacing and any sealer.
  • Pavers: manufacturer and product line, color, pattern, bedding layer, edge restraint and joint sand.
  • Artificial turf: product name, face weight, pile height, infill type and amount per square foot, and how seams are joined.

Drainage

Where water will go: the slope of the new surface, any area drains, pipe runs, downspout connections, and the outlet. If the estimate says nothing about drainage, ask.

Walls, steps and edges

Wall height and length, footing, drain rock and weep holes; step count and material; borders and transitions between surfaces.

Permits and engineering

Whether a permit is needed, who pulls it, who pays for it, and whether an engineer's design is included for walls that need one.

Schedule, cleanup and site protection

Estimated start date and working days, how the site and your property will be protected, and final cleanup.

Allowances, exclusions and change orders

Allowances are budget placeholders for things not yet chosen, such as "lighting fixtures: $1,500 allowance." If your final choice costs more or less, the price changes. Make sure allowances are realistic, not set low to make the total look smaller.

Exclusions list what is not included, such as irrigation changes, electrical work, repairs to hidden problems, or HOA fees. Read them carefully. A short exclusion list on a cheap bid can hide a lot.

Change orders cover work that changes after the contract is signed, either because you ask for something different or because something unexpected turns up under the old surface. Every change should be written down and agreed, with its price, before the extra work is done.

From estimate to contract

An estimate is a proposal. The written contract is what you sign, and it should carry over everything in the estimate. In California, home improvement contracts have specific legal requirements. Among other things:

  • The contractor's license number must appear on the contract.
  • The down payment cannot exceed $1,000 or 10% of the contract price, whichever is less.
  • Progress payments should not get ahead of the work actually completed.
  • In many situations, you have a right to cancel within a set number of days after signing, and the contract must explain it.
  • The contract must include required notices, such as information about mechanics liens.

You can check any contractor's license at cslb.ca.gov. This is general information, not legal advice, so read your contract carefully and ask questions before you sign.

Comparing more than one bid

Lay the estimates side by side and compare them line by line, not by total. If one bid leaves out the base depth, drainage or demolition, ask for those details in writing before you decide. Our hardscape cost guide has a checklist of lines to compare and typical Orange County price ranges.

What our estimates include

After a free on-site assessment, we send a written estimate that lists each area, the demolition, the base depth, the surface specifications, the drainage plan, permits where needed, and the payment schedule. If anything is unclear, ask and we will explain it before you sign anything.

Questions people ask us about this

Is an estimate the same as a contract?

No. An estimate is a proposal describing the work and price. The written contract you sign is what binds both sides, and it should include everything from the estimate along with the notices California law requires.

Why is one estimate so much higher than another?

Usually because they describe different amounts of work: a deeper base, reinforcement, drainage, full demolition or permits. Compare the line items, not the totals. If the lower bid leaves those details out, ask for them in writing.

What if you find something unexpected under my old concrete?

We stop, show you what we found, and explain the options and cost. Nothing extra is done until you agree to a written change order.

How long is an estimate valid?

Each estimate should state how long its price is valid, because material costs change. If it has expired, ask for an updated price before signing.
