Windows & Exterior Doorsin Westmoreland County, PA

Drafty windows and doors that stick cost you twice: once on the heating bill and again when water gets into the wall. We set new windows and doors square, flash them properly and trim them clean, with our own crew.

The Work

Windows that seal,doors that close right.

Maybe you can feel the draft from across the room in January. Maybe the back door has to be lifted and shoved to latch, and the sill underneath has gone soft from years of rain getting in.

We look at more than the glass: how the opening is framed, whether water has been getting behind the trim, what the old flashing did or didn’t do. The crew that measures your openings is the crew that sets them.

What We Build

From one bad windowto every door in the house.

Some homes need one rotted window or a front door that finally fits. Others need every opening replaced at once. Here is the window and door work our crew takes on, from frame to trim.

  • 01

    Replacement windows

    New windows set into existing frames that are still sound, sized to the opening, shimmed square and sealed so they open, lock and stop drafts the way they should.

  • 02

    Full-frame replacement

    When the old frame or sill has rotted, we take it out to the studs, repair the framing, flash the opening and set a complete new window.

  • 03

    Entry doors

    Front and side doors hung plumb on a solid threshold, with weatherstripping that seals and a lockset that latches the first time without lifting or shoving.

  • 04

    Patio & sliding doors

    Sliding and hinged patio doors set level on a properly flashed sill pan, so they glide, lock and keep water from pooling under the floor inside.

  • 05

    Storm doors

    Storm and screen doors fit to the opening, adjusted so they close gently and seal, adding a layer of protection to the entry door behind them.

  • 06

    Bay & bow windows

    A bay or bow window framed out from the wall, supported and roofed, and insulated so the new window seat isn’t the coldest spot in the room.

  • 07

    New & enlarged openings

    Cutting a new window or widening one, with a header sized for the load, framing done right, and siding and trim patched so it looks original outside.

  • 08

    Basement & egress windows

    Replacement basement windows and code-sized egress windows, with the well dug, drained and the foundation cut where a basement bedroom needs a safe way out in an emergency.

  • 09

    Trim, capping & sills

    Interior casing and exterior trim replaced or wrapped in aluminum capping, with rotted sills cut out and rebuilt so the new window isn’t sitting on soft wood.

The Honest Version

What’s behindthe old trim.

Old windows and doors leak in ways you can’t see from inside. Pulling off the old trim is how we find damage before a new unit hides it.

01

The sills

What we usually findWindow sills and door thresholds gone soft and black from years of water running in where it shouldn’t.

What we do about itWe cut out the rot, rebuild the sill or subfloor, and set the new unit on solid wood.

02

The flashing

What we usually findNo flashing, or tape that failed years ago, so every storm sent water into the wall below.

What we do about itWe flash every opening with a sill pan and layered membrane so water drains out, not in.

03

The framing

What we usually findOpenings that are out of square, sagging headers, or framing that was cut when someone installed the last window.

What we do about itWe square up the opening and repair or replace the header before any new window or door goes in.

04

The gaps

What we usually findGaps around the old frames packed with a bit of fiberglass, or nothing, letting cold air straight in.

What we do about itWe seal the gap with low-expansion foam that won’t bow the frame, then trim it out tight.

Who Does the Work

We don’t sub it out.We build it.

Window companies often send an installer who sees the house once, works fast and leaves the rotted sill for someone else. Our carpenters fix what’s around the opening first, then set the window.

The usual way

  • A showroom sells you the windows
  • A rushed install crew sets them
  • Rotted sills caulked over, not fixed
  • Trim left for you to sort out

The AllTrades way

  • The carpenter who measures it installs it
  • Rotted framing repaired before install
  • Every opening flashed and sealed
  • Trim finished inside and out

How a Window Job Runs

Measured, set,and trimmed.

Most window and door jobs are done in a few days once the units arrive, longer when sills or framing need repair. Here is how it goes.

Start a Project
01

First Call

A carpenter answers, not a sales rep. Tell us which windows or doors are giving you trouble, and we’ll come measure and look at the openings.

02

Measure & Real Number

We measure every opening, check the sills and framing for rot, and give you a written price for the actual work before anything is ordered.

03

Ordering

Windows and doors picked with you, then custom-ordered to the exact sizes. Lead times vary, and we schedule the install around delivery.

04

Removal & Repair

Old units out one opening at a time, so the house is never left open. Rotted sills and framing repaired, then each opening flashed.

05

Set & Seal

New windows and doors set square, shimmed and foamed, then trimmed inside and out and caulked, with each one tested to open, close and lock.

06

Final Punch

Every sash, lock and screen checked, the site cleaned, old units hauled away. We walk the house with you and adjust anything that isn’t right.

The Investment

What windowsand doors cost.

Every opening is priced after we measure and check for rot, since a sill repair changes the number. Most of our window and door jobs land in these ranges.

Tier 01

A Few Openings

$3K – $10K

Problem windows or one door

Typically includes

  • A handful of units replaced
  • Removal & haul-away
  • Flashing & insulation
  • Interior & exterior trim

Tier 03

Full-Frame & New Openings

$40K+

Down to the studs

Everything in Whole House, plus

  • Full-frame window replacement
  • New or enlarged openings
  • Headers sized & framed
  • Siding patched to match

Every price comes after we measure and check each opening for damage. These ranges are where window jobs start, not where they cap out.

“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.”

Window & Door Questions

Before you replacea window.

What people ask before replacing windows or doors. Don’t see yours here? Ask us when we come out to measure.

Ask a Question
[ 01 ]Replacement or full-frame: which do we need?

If the frame and sill are solid, a replacement fits inside them. If there’s rot, full-frame is the right call, and we show you why at the walkthrough.

[ 02 ]How long does installation take?

Usually a few days once the windows arrive. Custom sizes take several weeks to come in, and we set each opening and close it the same day.

[ 03 ]Will you fix rotted sills and trim?

Yes, it’s part of the job. Setting a new window on a soft sill just hides the problem, so we repair the wood first and price it in up front.

[ 04 ]Do you install exterior doors too?

Front, side, patio and storm doors. We hang them plumb, seal the threshold, and adjust the hardware so the door latches without a shove every time.

[ 05 ]Can you add a window where there isn’t one?

Yes. We cut the opening, frame in a header sized for the wall above, flash it, and patch siding and drywall so it looks original.

[ 06 ]Do you haul away the old windows?

Yes. Old units, trim and debris leave with us, and we clean up inside and out at the end of each day so the house stays livable throughout.

The Rest of the Work
