Service
Hardscaping is the part of a garden that does not grow — the paving, the walls, the steps, the stone. In Seattle it is also the part that decides whether the rest works, because a garden on a slope that takes thirty-eight inches of rain a year is really a drainage problem with plants on top. Get the hard structure right and the soft landscaping has somewhere to live. Get it wrong and you spend a decade repairing it. Most of our work starts as one element — a patio that floods, a bank nobody can use, a driveway breaking up — and turns out to need two or three of them solved together, because they share the same ground and the same water. This page covers what each element costs and which ones a given problem actually needs. The individual pages go into how each one is built.

What is included
Flat, dry, usable ground that stays where you put it.
The usable outdoor room. Material, size and the falls it needs to shed water set the price far more than the paver you pick. See paver patios for layouts and sizing.
The widest range on this page, because a two-foot garden wall and an eight-foot engineered wall are different jobs sharing a name. Height, access and whether it needs a permit move it. See retaining walls.
Cheaper per foot than a patio because the units are simpler, more expensive overall because the base has to carry a car. See driveway paving.
Priced per square foot but driven by linear metres and by how many level changes the route has to absorb. See pathways and walkways.
Natural stone, brick and veneer, on walls, piers and chimneys. The most labour-intensive surface on the page. See masonry.
A built fire pit is a day; a fireplace with a flue is a build. Both usually land on a patio, which is why they are priced and scheduled together. See fire features.
Not decorative and not optional on most Seattle lots. It is the line item that stops the other six failing. See drainage.
Why people call us
How we build it

Seasonality. Hardscaping runs year-round in Seattle, unlike planting. Excavation in a wet January is slower and the site is messier, so winter is better for walls and paving than it is for anything that needs soil to be workable. The busiest enquiry period is February to April for work people want finished by summer, which means booking in autumn usually buys a better slot than booking in spring.
Before anything is priced. Where the water arrives, where it currently goes, and where it will go once a few hundred square feet of ground stops absorbing it. On a sloping lot this changes the design, not just the drainage line.
Walls before paving, drainage before both, and anything needing machine access before the route in is closed off. A correct sequence is most of what keeps a multi-element job from costing twice.
Wall height, Environmentally Critical Area, impervious surface limits. Three elements each individually exempt can still cross a threshold together, and finding that out mid-build is the expensive version.
Excavation to the depth the use requires, compaction in lifts, and the drainage placed as the structure goes up rather than added at the end. None of this is visible when the job is done, which is why it is where a cheap quote saves money.
Paving, wall faces, caps, stone. The part everyone is paying attention to, and the fastest part of the job when the three steps above were done properly.
Edges, jointing, the soft landscaping back in, and the levels checked against where the water is meant to go. We walk the finished fall lines with you rather than asserting them.
What it costs
A single-element job — a patio, or one wall — is usually quoted per square foot at the rates above. A whole-garden hardscape across three or four elements lands between $25,000 and $120,000 in this market, and the spread is mostly access, slope and how much of the ground has to be rebuilt before anything visible goes on it. Every figure here is the same number published on the individual service page for that trade; this page does not price differently from the pages it links to.
That is a market range, not a quote. Your price is fixed in writing after we have seen the site, and it does not move once agreed.
No deposit is required to start. Payment comes after the work is finished — not before.
A fixed, accurate price is guaranteed before the job starts. We do not quote low and raise it mid-project.
A 0% interest payment plan is available for up to 6 months.
Hardscaping work carries a warranty. Vegetation is excluded.

Alex and his crew do AMAZING work. I had a really great experience and can't recommend them enough. First, Alex was prompt and courteous when responding to any questions both before and during the work. When we met to estimate the project I had a variety of things (general yard cleanup, re-leveling existing flagstones, putting in new flagstones, installing steps, some tree removal, and re-dsigning the path down the side of the house). He was very accommodating, paid attention to ALL the details, and made several recommendations (I was unsure of some of them, but i went with them and it was DEFINITELY the right choice). Second, when they were doing the work, the guys were completely professional. They showed up when they said they would and finished on schedule (all of the work above was completed in ONE week). They were even careful of existing plants and sprinkler hoses within the ground. Last, the work itself came out beautifully. Alex's crew are efficient and have great attention to detail. The yard was a complete mess before (with invasive plants) and its been totally transformed, see the pics. I couldn't be happier with the end result. You gotta call these guys.

Alex and Aden Landscaping did an amazing job on our patio made of pavers. Fast, professional, and high quality work. Much cheaper than system pavers quote I got earlier.

They're the best landscapers in Seattle. Hired them for my house near Queen Anne and they did exactly what I asked them to do. They did retaining walls and landscape design for me. I loved every detail. Highly recommended.

Alex is one of the best contractors I've worked with! He's very creative and really sweats the details, which shows in the final product. Our backyard turned out very functional and beautiful! Our house is built on a steep hill so it was hard for us to see how we would utilize the backyard space because we had two retaining walls that minimized the main area. Alex proposed a great solution that maximized the main area and we couldn't be happier.

We could not be happier with the patio cover, retaining wall and new turf that Aden landscaping put up for us Alex and his entire team were incredible, and we are very impressed and thankful. They were polite, professional and even worked through lunch to get everything done ASAP. Everyone was also early to every appointment, which is rare these days. They went above and beyond expectations and took care of everything we asked for. We're all very impressed by aden landscaping and they have certainly made a customer for life! Their pricing was very reasonable and they were well worth the money.

We recently hired Alex and team to install artificial turf and a paver patio in a new house we moved into. We're very happy with the quality of the work and outcome. We evaluated Aden along with two other providers in getting a bid. Although they were not the most competitively priced initially, Alex was very willing to negotiate and meet our budget based on the competing bids we received.

I worked with Alex. Upfront, honest and very transparent about the work we requested. As an overview, this is what we requested and had done. - Removal of several trees and brush from back and front yards - Installation of 400 sq ft paver patio w/ high gloss sealant - Installation of 280 sq ft playground area with wood chips - Removal and replacement of all grass Alex and his team were prompt, on time and respectful of the surrounding properties. He kept us informed and let us know what to expect at every turn. The quality of work was superb, and cost was very fair compared to other competitive bids. I will be referring him to all friends and family for their landscaping needs!

We needed a solution with the sliding soil in our backyard (Seattle location). Eric & Alex suggested building a retaining wall and we are very satisfied with the solution and the results. Thank you.
Where we build it
Before you call
Something not answered here? Call (425) 331-9811 and ask — we would rather talk it through than have you guess.
Everything in a garden that is built rather than grown: paver patios and driveways, retaining and seat walls, walkways, steps, stone and brick masonry, fire pits and fireplaces, and the drainage underneath all of it. The counterpart is softscape — lawn, planting, soil, trees. Most gardens need both, and the usual order is hardscape first, because it involves machines, excavation and changes to where water goes, none of which you want happening after the planting is in.
Per square foot, between $18 and $120 depending which element you mean — walkways and driveways at the lower end, natural stone masonry at the top, patios and walls in between. As a whole project, a single element on an accessible flat lot can be $8,000–$15,000, and a full garden across three or four elements on a slope is typically $25,000 to $120,000. The three things that move a quote most are access for machinery, how steep the ground is, and how much of what is already there has to come out first. We quote fixed, and there is no deposit.
Drainage, then whatever is structural, then the surfaces. That order is not a sales preference — it is that each one is buried under the next. Putting a patio down before fixing where the water goes means lifting the patio to fix it later, and building a wall after the paving means bringing a machine across the finished surface. If the budget covers one phase now, the right phase is the one that is underneath, and we will quote it so the later phases connect to it rather than requiring it to be redone.
It depends on the element and often on the total. A retaining wall is exempt only if it is four feet or lower measured from the bottom of the footing, outside an Environmentally Critical Area, and causing no damage to adjoining property. Paving generally does not need a construction permit but can run into impervious surface limits on a small lot, and that limit counts your patio, driveway and walkway together rather than separately. The case that catches people is three individually exempt elements that cross a threshold combined. We check the parcel once for the whole job before quoting.
Usable outdoor space is worth more here than a decorative one, which is a Seattle-specific answer: a flat, dry, covered-or-not area that works nine months a year reads as extra room, and a steep unusable bank reads as a problem the buyer inherits. The elements that hold value best are the ones that fix something — a wall that makes a slope usable, drainage that stops a wet lawn, a driveway that stops breaking up. The ones that hold value least are highly specific installations built to one person's taste. We will tell you which half of that a given idea falls into.
Landscaping is the whole garden; hardscaping is the built half of it. A landscaper who only does softscape will plant around a drainage problem rather than fix it, and a hardscape contractor who does not think about planting leaves you with a lot of paving and nowhere for water to go. We do both, which mainly matters in the sequencing — knowing that the irrigation line crosses where the wall footing goes is cheaper to know before the footing is poured.
Yes, and most of our higher-value work is exactly that — Magnolia, Queen Anne, West Seattle, the north-end bluff streets. A steep lot usually wants terracing rather than one tall wall: two four-foot walls stepped apart generally cost less than a single eight-foot wall, avoid the engineering and permit the tall one triggers, and leave usable ground between the levels instead of a cliff. Where the lot sits in an Environmentally Critical Area the four-foot exemption stops applying and the process takes longer, which we will tell you before quoting rather than after.
A single patio or one wall is typically one to two weeks on site. A multi-element garden is three to six weeks, and the variable is almost never the visible work — it is excavation, disposal, and how much base has to be built. Access is the other big factor: a job a machine can reach moves several times faster than one where everything is barrowed through a side return. We give you a week-by-week sequence with the quote, not just a finish date.
Concrete pavers and natural stone both do well; the failures we are called out to are almost never the material. They are the base under it and the drainage behind it. Permeable pavers are worth considering where impervious surface limits are tight, because they can let you build more area within the same allowance. On shaded north-facing ground anything smooth gets slippery with algae, so texture matters more than it does in a sunnier climate, and sealing is maintenance rather than a one-off.
Yes — common-area paths, entrance walls, parking and walkway repair, and multi-year programmes for associations. The work is the same; the difference is documentation and scheduling around residents rather than around one household. See HOA and association landscape management for how those are quoted and run.

We come out, look at the site properly, and put a fixed written price together. No deposit, and nothing changes once the price is agreed.
