How We Approach Pergola Construction
We design and build pergolas across Bergen and Passaic County, NJ, on new decks, existing decks and standalone footings. A pergola is a roof structure without a roof, and that is exactly what makes it easy to get wrong. The rafters have to span without sagging, the posts have to land somewhere that can actually carry them, and the whole thing has to resist wind uplift — an open frame catches more than people expect.
When a pergola goes over an existing deck, the first question is never the design. It is whether the deck below was framed to carry point loads at those four spots. Often the answer is that the posts need to come down to their own footings, or the framing underneath needs reinforcing. We would rather find that out at the estimate than after the posts are up.
The part you actually experience is shade, and shade is a geometry problem. Rafter depth, spacing and direction decide when the shade lands and how much of it you get. A pergola sized for looks and not for the afternoon sun is a very expensive shade structure that does not shade anything.

How It Works
Our proven process from first call to final walkthrough.
1
1
Free in-home estimate
We look at where you want it, where the sun actually comes from, and what is underneath. If it is going over an existing deck we check how that deck was framed.
2
2
Load path and footings
Four posts are four point loads. We work out whether they can land on the existing structure or need to carry through to their own footings below the frost line.

3
Span, spacing and shade
Rafter depth and spacing are sized for the span, then the spacing and direction are set for when you actually use the space — afternoon shade needs different geometry than midday.

Permit where required
An attached pergola, or one over a raised deck, generally needs a permit and a zoning setback check. We confirm what your township wants and file it.

Build and walkthrough
Posts, beams, rafters and bracing go up with hardware rated for uplift, and we walk the finished structure with you.
What Pergola Construction Covers
Typically 3–5 days on site, longer with new footings.
Freestanding pergolas
A standalone structure over a seating area, fire pit or a corner of the yard.
- Frost-depth footings
- Post bracing and uplift hardware
- Orientation planned for afternoon shade
Deck and pergola together
Both built at once, with the deck framing designed from the start to carry the pergola posts.
- Framing sized for point loads
- Matched posts, wraps and finish
- Lighting runs planned into the beams
Structure
Where a Pergola Is Actually Won or Lost
An open frame looks simple, which is why the engineering behind it is usually the part that was skipped.
Posts land on something real
Four posts concentrate load at four points. On an existing deck that often means reinforcing below or carrying the posts down to their own footings.
Rafters sized to span
Depth and spacing come from the span, not from a picture. Undersized rafters do not fail dramatically — they sag slowly, and it shows along the top line.
Uplift hardware
An open frame catches wind from underneath. Connections are made with hardware rated to hold it down, not just to hold it together.
Shade geometry
Rafter spacing and direction decide when shade lands. We orient the structure for the hours you use the space rather than for the plan view.
Attached or freestanding
Attaching to the house means a ledger, flashing and a permit conversation. Freestanding avoids all three but needs its own footings and bracing.
Built to match the deck
Post wraps, beam profiles and finish are matched to the deck below, so it reads as one structure rather than an addition.
Options
Choices That Change the Result
Most pergola decisions are about how much sun you keep and how much maintenance you sign up for.
Open rafters
The classic look. Dappled shade that moves through the day, and nothing to catch leaves or snow.
Tighter rafter spacing
More shade for more of the day, at the cost of some openness and a heavier structure to carry.
Cedar and pressure-treated
Cedar holds a finish and looks better bare; pressure-treated costs less and wants sealing. Both are real options and we price them side by side.
Composite post wraps
Wrapping posts in the same composite as the deck removes the part of the pergola that needs re-finishing most often.
Lighting and fans
Runs are planned into the beams while the structure is open. Retrofitting them afterwards is visible and awkward.
Built with the deck
If the deck is being built at the same time, the framing can be designed to carry the posts from the start. That is always cheaper than reinforcing later.
What Drives the Cost of a Pergola
Two pergolas with the same footprint can be priced far apart. These are the reasons why.
- Span between posts
- Longer clear spans need deeper rafters and beams. The jump from a 10-foot to a 16-foot span is structural, not cosmetic.
- Attached or freestanding
- Attaching saves two posts but adds a ledger, flashing and a permit conversation. Freestanding adds footings instead.
- What is underneath
- Posts landing on an existing deck often mean reinforcing the framing below or carrying the posts to their own footings.
- Timber choice
- Cedar against pressure-treated is the main fork — and wrapping posts in composite adds cost now to remove refinishing later.
- Rafter density
- Tighter spacing means more shade and more lumber. The look you want overhead is a real line item.
- Lighting and power
- Runs routed through the beams while the structure is open are cheap. The same wiring retrofitted later is not.
Before you build
Decisions to Settle Before the Posts Go In
A pergola is hard to move and expensive to change. These questions cost nothing to answer now and a great deal to answer later.
Where is the sun at 5pm?
Shade is a geometry problem. Orient the rafters for the hours you actually sit outside, not for the plan view of the yard.
Dining or lounging underneath?
A table wants clear height and headroom at the edges; a lounge corner tolerates a lower, denser canopy. It changes the frame.
Will a roof come later?
If polycarbonate panels or a louvred roof might come in a few years, the structure needs to carry that load from day one.
One open side or two?
A privacy screen on the neighbour's side changes wind loading and where the bracing goes. Decide before, not after.
Match the deck or contrast it?
Post wraps and finish matched to the deck read as one build. Contrast can work, but it should be a decision, not an accident.
Who maintains it?
Bare cedar silvers gracefully but wants oiling to stay brown. Wrapped posts and aluminum never ask for anything.

“The job that was done by House of Decks LLC for our new deck was really good. They started by removing the old deck and then assisted us in choosing a layout and material options, explaining everything before beginning the process. Their workers arrived on schedule, were fast at working and kept our backyard clean. The end result is a very solid deck with straight boards and railings, which has greatly improved the backyard area. We are really pleased with their work and would recommend them for any deck installation. Thank you guys!”

Frequently Asked Questions
The questions homeowners ask us at almost every estimate.
Do I need a permit for a pergola in New Jersey?
Usually yes if it is attached to the house or sits over a raised deck, and zoning setbacks apply either way. Some freestanding structures under a size threshold are exempt in some townships. We confirm what your town requires and file it if needed.
Can a pergola go on my existing deck?
Sometimes, and it depends entirely on how that deck was framed. Four posts are four concentrated loads. We check the framing below before agreeing to it, and if it will not carry, the posts go down to their own footings.
How much shade does a pergola actually give?
That is set by rafter depth, spacing and direction — and by the time of day you care about. A structure oriented for midday gives you very little at five in the afternoon. We size it for when you use the space.
Cedar or pressure-treated?
Cedar looks better bare and holds a finish well. Pressure-treated costs less and wants sealing to stay looking right. We quote both against your actual footprint rather than recommending one by default.
Will it stand up to wind?
It has to be built for uplift, which is the load people forget with an open frame. Connections use hardware rated to resist it rather than ordinary fasteners.
How long does a pergola take to build?
Typically three to five days on site once material is in, longer if footings are involved and the concrete needs to cure before the posts go up.
Can you add lighting or a fan?
Yes, and it is far easier to plan it while the structure is open. Runs are routed through the beams so nothing is surface-mounted afterwards.
Can you build the deck and pergola together?
That is the best case. If we frame the deck knowing where the posts land, the structure carries them from the start and you avoid paying to reinforce it later.
