Landscaping and hardscaping in Allegheny County

Allegheny County is our southern market, and the terrain changes character as soon as you cross the line. The North Hills is genuinely hilly, and slope drives almost every decision on a property โ€” where a patio can physically sit, how many tiers a wall needs, and where the water coming off the ground above you is going to end up.

The housing stock is mature. A lot of what we do here is renovation rather than installation: taking out foundation shrubs planted too close to the house when it was built, rebuilding timber retaining walls that have finally rotted through, and re-cutting bed lines that have crept outward for twenty years.

Tree cover is the other constant. Pine, Marshall, McCandless and Hampton carry serious canopy, which means shade where turf will not establish, root competition in every bed, and enough leaf load to kill a lawn over winter if it sits. Shade-tolerant seed blends, selective canopy work and, where grass genuinely will not grow, artificial turf all get used here.

In Sewickley, Fox Chapel and Franklin Park the finish standard is higher and the deer pressure is heavier. A beautifully planned bed of hostas and arborvitae is a feeding station in those neighbourhoods, so plant selection is deliberate and anything the deer will take gets protected through its establishment years.

We work the City of Pittsburgh itself too, mostly the northern neighbourhoods and mostly on larger projects where the travel is justified โ€” city lots bring access limits, permits, and neighbours close enough that cleaning the site every evening is not optional.

On the ground

What the North Hills demands

  • Genuine slope

    Hillsides steep enough that a patio needs a wall before it needs pavers

  • Mature tree cover

    Dense shade, root competition and a leaf load that smothers turf over winter

  • Heavy deer pressure

    Plant selection has to be deliberate or the bed becomes a feeding station

  • Established landscaping

    Thirty-year-old plantings long outgrown and planted too close to the house

  • Water from uphill

    On a slope the problem often starts on somebody else's ground

Landscaping

Landscape design for
sloping, wooded lots

Designing on a hillside is a different exercise. You are deciding what is level, what is terraced and what stays planted, before anything about the look is settled.

Under mature canopy the planting list narrows fast โ€” shade tolerance and deer resistance rule out most of what looks good on a nursery bench.

  • Grade and drainage resolved before the planting plan
  • Shade and deer-tolerant species specified
  • 3D rendering so you can see the terracing before it is built

Hardscaping

Retaining walls and
patios that hold a hillside

On a North Hills lot the retaining wall usually is the project. Get the wall right and the patio on top of it is straightforward; get it wrong and you are rebuilding both in five years.

Every wall gets drainage stone and fabric behind it, courses set on a compacted base, and footings below the frost line.

  • Tiered walls where a single height would be wrong
  • Drainage behind the wall, every time
  • Engineered base under patios, not sand over clay

Lights Installation

Landscape lighting under
heavy tree cover

Mature trees are the best thing to light in this county and the main reason people call. Uplighting a specimen oak changes a property after dark more than any amount of path lighting.

Runs are buried, zoned, and the transformer is sized with room for the next phase.

  • Specimen tree uplighting
  • Zoned circuits so areas can run separately
  • Solid brass fixtures, buried cable runs

SOD Installation

Lawns that establish
in shade and on slope

Two problems here, often on the same property: not enough light, and too much gradient for water to stay where you put it.

Shade blends where there is a chance, grading and drainage first where there is not, and artificial turf where the honest answer is that grass will never hold.

  • Shade-tolerant seed blends
  • Slope stabilised before seeding
  • Artificial turf where grass genuinely will not establish

Good to know

Questions we get from Allegheny County

Do you work in the City of Pittsburgh?

Yes, mainly the northern neighbourhoods and mainly on larger projects where the travel is justified.

What can I plant that the deer will leave alone?

More than people expect, but it has to be chosen deliberately. We specify deer-resistant and protect anything vulnerable while it establishes.

Will grass grow under my trees?

Sometimes, with a shade blend and some canopy work. Where it will not, we will tell you rather than sell you a lawn twice.

My timber retaining wall is failing. Can it be repaired?

Usually not worth it. Rebuilding in segmental block with proper drainage costs more once and then stops costing.

Do you handle permits?

Where a wall or structure needs one, yes, as part of the job.
