Decks & Covered Patiosin Westmoreland County, PA

The good months here are short, so the space outside the back door should earn every one of them. We build decks, covered patios and three-season rooms with our own crew, on solid footings, flashed to the house and ready for winter.

The Work

More of the yearspent outside.

Maybe the old deck flexes underfoot and the railing wobbles when you lean on it. Maybe you’d eat outside every night if the sun and the rain would just cooperate, and the bugs would stay out.

We start where most deck problems start: where it attaches to the house and what it stands on. Then we plan the space around how you’ll use it. The carpenters who dig the footings are the ones who build the railings.

What We Build

From a new deckto a three-season room.

Some yards need a new deck where a tired one stood. Others need a roof over the patio, or screens and glass so it works from spring to fall. Here is what we build.

  • 01

    Decks

    New decks framed with treated lumber on footings dug below the frost line, with joists spaced for the decking and a ledger bolted and flashed to the house.

  • 02

    Composite & wood decking

    Composite boards that won’t splinter or need staining, or real wood if you like the look, installed with hidden fasteners or screws set clean and in straight lines.

  • 03

    Covered patios

    A roof over the patio or deck on posts and beams, shingled to match the house and tied into the roofline so water runs off, not in.

  • 04

    Three-season rooms

    A room with a roof, a floor and walls of screens or windows, usable from early spring to late fall without needing to be heated through the coldest months.

  • 05

    Screened porches

    Screened walls framed into a new or existing covered porch, with a screen door and a floor built so bugs and leaves stay out all summer.

  • 06

    Railings & stairs

    Railings at the right height with balusters close enough for small kids, and stairs with proper rise, run and landing so the deck is safe to use.

  • 07

    Deck rebuilds & repairs

    Rotted boards, loose railings and failing ledgers replaced, and the framing underneath checked, so an old deck either gets fixed properly or rebuilt on a solid structure.

  • 08

    Pergolas & shade

    Open-beam pergolas and shade structures built over a deck or patio, set on solid posts and sized so they look right against the back of the house.

  • 09

    Lighting, power & fans

    Step and post lights, outdoor outlets and ceiling fans under the roof, wired and rated for outdoor use so the space works well after dark, too.

The Honest Version

What’s holdingthe old deck up.

Most deck failures start where you can’t see them, under the boards and behind the trim. Checking those spots first is how a new deck outlasts the old one.

01

The ledger

What we usually findA ledger nailed to the house with no flashing, letting water rot the rim joist behind it for years.

What we do about itWe bolt the new ledger through the rim, flash above and behind it, and repair any rot first.

02

The footings

What we usually findPosts sitting on blocks or shallow footings that heave in the frost and leave the deck out of level.

What we do about itWe dig footings below the frost line and set posts on proper bases so the deck stays level.

03

The framing

What we usually findUndersized or widely spaced joists, which is why the deck bounces when you walk across it.

What we do about itWe size and space joists for the span and the decking, then add blocking so the floor feels solid.

04

The railings

What we usually findRailings fastened with a few screws, balusters too far apart, and posts that move when you push on them.

What we do about itWe bolt railing posts into the framing and space balusters so they meet code and hold your weight.

Who Does the Work

We don’t sub it out.We build it.

Plenty of decks are built in a weekend by whoever was free, on footings nobody inspected. Ours are framed by carpenters who dig the footings, bolt the ledger and set every railing post themselves.

The usual way

  • A quick quote off a photo
  • Shallow footings, nailed-on ledger
  • Railings that loosen in a season
  • Nobody back when the boards cup

The AllTrades way

  • Quoted and built by the same carpenter
  • Footings dug below the frost line
  • Ledger bolted and flashed to the house
  • Railing posts tied into the framing

How a Deck Job Runs

Dig, frame,and build it right.

Most decks take one to three weeks once the permit is in hand, longer with a roof or a three-season room. Here is what each stage looks like.

Start a Project
01

First Call

You get a carpenter, not an order desk. Tell us what you want out back, and we’ll come look at the yard, the house and the old deck.

02

Site Visit & Real Number

We check where it attaches, how the ground slopes and what the township requires, then write up what it will cost so you know before you commit.

03

Design & Permits

Layout, decking, railing and roof style chosen together, drawings made for the permit, and materials ordered once everything is approved.

04

Footings & Framing

Footings dug and inspected, then posts, beams, ledger and joists framed and flashed. For covered patios and rooms, the roof framing goes on next.

05

Decking & Finish

Decking, stairs and railings installed, then screens, windows, lighting and trim, and the crew checks in with you every week until it’s done.

06

Final Punch

Railings tested, stairs measured, every board fastened and the yard cleaned up. We walk the finished space with you and get the final inspection signed off.

The Investment

What a deckor patio costs.

We price decks and covered spaces after seeing the yard, the size and whether a roof is part of it. Most of our outdoor projects fall somewhere within these ranges.

Tier 01

Deck

$15K – $35K

A new deck, open to the sky

Typically includes

  • Footings below the frost line
  • Framing, ledger & flashing
  • Composite or wood decking
  • Railings & stairs

Tier 03

Three-Season Room

$70K+

Walls, screens & windows

Everything in Covered Patio, plus

  • Screened or windowed walls
  • Finished floor & ceiling
  • Door out to the yard
  • Outlets & lighting inside

Prices are written after we see the yard and the house in person. These ranges show where outdoor projects begin, not their limit.

“I couldn't recommend the All Trades team more! They did a wonderful job on the drywall and tile for a bedroom and bathroom remodel. They were responded to me quickly, were kind and easy to work with, efficient and attentive to detail. They checked in along the way to make sure we were on the same page about the project. I couldn't be happier with how it turned out!”

“My wife and I have been kicking around the idea to get our master bathroom remodeled for the last couple of years but never pulled the trigger. While getting a roof repair done due to some windstorms, I asked the gentleman for some bathroom remodel references and he gave me AllTrades contact info. I met with James and he was really good about understanding what we wanted to do. He allowed us to feel comfortable and confident in his teams ability to get us what we wanted. Once we agreed on the quotes (very detailed and broken down) the work started within days. This was a full gut and remodel which involved moving some plumbing and closing up a window and cutting in a new one on a different wall. The two gentleman doing the job were fantastic. Super nice and cordial to my whole family. Brison and Vinny, thank you for making my family feel safe while you were transforming our bathroom into a much more functional and beautiful space! This group does all kinds of work as isn't limited to just bathrooms. I recommend you at least speak to them and get some quotes for any work you are looking to get done.”

Deck & Patio Questions

Before you buildout back.

What homeowners ask before building a deck or covered patio. Don’t see your question? Ask us at the site visit.

Ask a Question
[ 01 ]Composite or wood decking?

Composite costs more up front but won’t splinter and doesn’t need staining. Wood costs less and looks natural but needs care every few years. We’ll walk you through both.

[ 02 ]Does a deck need a permit?

In most townships, yes, especially for anything attached to the house or built above a certain height. We prepare the drawings and handle the permit and every inspection.

[ 03 ]Can you add a roof over our existing deck?

Often, if the deck’s footings and framing can carry the extra weight. We check them first, and reinforce or rebuild what’s needed before the roof goes on.

[ 04 ]What’s the difference between a three-season and a four-season room?

A three-season room isn’t insulated or heated for winter, so it costs less. A four-season room is built like the rest of the house and used year-round.

[ 05 ]Can you fix our old deck instead of replacing it?

Sometimes. If the footings, ledger and framing are sound, new boards and railings may be all it needs. If not, we’ll tell you honestly that it’s time to rebuild.

[ 06 ]When is the best time to build a deck?

Spring through fall is ideal, but we can dig footings and frame in most weather. Planning over the winter usually means an earlier spot on the spring schedule.

The Rest of the Work
