Installed by the People Who Fix Installations

Window Installation

Most of the rot we repair started on someone's installation day. So when we install a window, we build the opening the way our repair crews wish everyone would — flashed, sealed, and drained so there's nothing for a future crew to find.

The Honest Math

Nobody told you it could be repaired.

Most homeowners hear one option — replacement — because that's what the company at the door sells. Here's the comparison nobody hands you.

Repair with RotGone

$1,200 – $1,800
per window, repaired in place
  • Original wood stays — including profiles nobody manufactures anymore
  • 1–2 weeks, not months of lead time
  • Same sightlines, same glass line, same house
  • 5-year workmanship warranty

Full replacement

$3,500+
per window, wood-to-wood replacement
  • "5–8 windows for $23,000" works out to $2,900–4,600 each
  • Vinyl swaps old-growth wood for plastic that can't be repaired later
  • 4–8 weeks including manufacturing lead time
  • Trim, sills and interior casing get rebuilt around the new unit

Prices depend on how far the decay actually goes — that's what the free assessment is for. And we'll tell you honestly when replacement really is the right call; it happens, and you'd rather hear it from us than find out afterwards.

We've seen how installations fail.
That's why ours don't.

There's a strange gap at the heart of the window business: the people who install windows almost never see how installations age. The crew that sets a unit in West Caldwell today will never open that wall again — the consequences of installation day surface a decade later, as someone else's service call. We are that someone else. Repair is our first trade, and a large share of it is forensic: stripping trim from a fifteen-year-old window in Livingston to find framing you can press a thumb into, tracing the water back, and finding — nearly every time — a decision made in twenty minutes on installation day. The missing pan. The reversed lap. The caulked weep. Installation is the only construction task we know of where the feedback loop is so long that bad habits never catch up with the people who have them.

Our installation service exists to close that loop. Same company, opposite ends of the timeline: the crews that diagnose failed installations set the standard for how ours are built, and the details below aren't marketing — they're the specific answers to the specific failures we repair every week. It also means our incentives run honestly. A company that profits from repairs has no reason to install badly and every reason to install so well it never sees the house again; our 5-year workmanship warranty on installation workmanship is us signing that sentence.

When installation is the right call

  • A window past the repair line — our standing rule: more than half the structural wood gone means replacement is the honest answer. The assessment says which side of the line you're on, free.
  • Storm or impact damage — a destroyed unit needs a new unit; the opening still deserves a proper pan and flashing while it's exposed.
  • Additions and new openings — first-time installations, where doing it right costs no more than doing it fast.
  • Owner-supplied units — you bought the windows; we make sure the wall around them is on your side.
  • Replicated originals — historic and discontinued windows built by our replication shop, hung and tuned by the same hands.

And when installation isn't the right call, you'll hear that from us too — it's the family rule. A homeowner in Chatham who calls about "replacing a drafty window" usually has a window that needs weatherstripping and a balance, at about 80% less than a new unit installed. We'd rather earn the small honest job and the referral than the large unnecessary one. When the big job is real, though, it gets built like this page describes: assessed within 1–2 days, quoted in writing, completed within 1–2 weeks of units arriving, by a fully insured crew that answers photos the same day.

The Details That Decide

What separates an install
from a future repair.

Four invisible details determine whether a window installation lasts. They're invisible at handoff — and unmistakable fifteen years later.

The sill pan is the assembly's insurance policy: a waterproof tray under the window, back-dammed and sloped outward, so any water that ever gets past the unit drains to daylight instead of into the framing. Skipping it saves twenty minutes and causes the single most common rot pattern we repair. Shingle-lapped flashing means every layer overlaps the one below it the way roof shingles do, so gravity carries water out over each seam — tape and housewrap layered in the wrong order do the opposite, funneling water into the wall with remarkable efficiency. Selective sealing is knowing where not to caulk: the sides and top get sealed, the bottom drains, because a window assembly must be able to weep the water it will inevitably admit. The air seal lives on the interior side — a continuous seal between frame and rough opening that keeps humid indoor air out of the cold wall cavity, where it would otherwise condense all winter and feed the quiet rot that shows up as a mystery stain in year ten.

None of this is exotic. It's all in the manufacturers' own instructions — the ones that go unread on installation day when the schedule says four windows before lunch. Our advantage isn't secret technique; it's motive. A crew that spends half its week rebuilding rotted frames and soaked sills around other people's shortcuts does not take those shortcuts. We've seen exactly how every one of them ends.

Installation FAQ

Asked by homeowners who've
been burned before.

Why hire a repair company to install windows?

Because we've spent 8+ years opening up other people's installations to fix what went wrong inside them. Nearly every rotted frame, soaked sill, and moldy jamb we rebuild traces back to installation day: flashing that was skipped, sill pans that were never formed, flanges sealed on the wrong side, gaps stuffed with fiberglass instead of sealed against air and water. Installers rarely meet those failures — they surface five to fifteen years later, long after the truck has moved on. We meet them weekly. That autopsy experience is the qualification: when the crew that repairs water damage for a living installs your window, every detail is chosen by people who know precisely which shortcuts turn into which repairs, because we've invoiced for all of them. We install windows we'd be proud to repair — and would rather never have to.

What actually goes wrong in a bad window installation?

Water management, almost always. A window opening is a hole in a rain screen, and the installation's real job — beneath the leveling and shimming — is to guarantee that water arriving at that hole ends up outside the wall. The classic failures: no sill pan, so water that gets past the window (it always eventually does) soaks the framing under it instead of draining out; reversed laps, where housewrap or flashing tape is layered so water runs behind the layer below it, straight into the sheathing; caulk as strategy, sealing the bottom flange so water that enters the assembly is trapped inside; and foam-and-forget, where a gap is filled for insulation but never sealed for air, so humid interior air condenses in the wall cavity every winter. None of these is visible at handoff. All of them are visible to us, years later, as the rot repairs on our rotten window frame page. Our installations exist so that page never features your house.

Do you install windows you didn't sell?

Yes — installation stands on its own. If you've already ordered units, or your architect specified a brand, or you're replacing one storm-damaged window with a matching unit you sourced, we'll install what you have and install it properly. We'll also tell you, before it goes in, if something about the unit worries us — a flange design that needs extra care, a size that's tight for the rough opening — because catching that on the ground beats discovering it on the wall. Where we do supply the window, our repair-first DNA shapes the recommendation: we have no exclusive brand allegiance and no volume quota, so the unit we suggest is the one whose construction we'd want to service in fifteen years. And when the opening calls for something no catalog carries — a historic profile, a discontinued line — the answer is our own custom window replication, built to match and installed by the same hands.

Is installation quality really worth paying attention to? The window has a warranty.

The window's warranty covers the window — the glass seal, the hardware, the frame material. It does not cover the wall around it, and the wall is where installation failures do their damage. When a missing sill pan lets water into the framing, the manufacturer owes you nothing: their product performed; the hole it sat in didn't. The repair bill for that distinction lands on the homeowner, and it's the kind of bill we know intimately, because rebuilding rotted framing, sheathing, and interior finishes around a perfectly functional window is bread-and-butter work for our repair crews. That's the quiet economics of installation: the cheapest line item on a window project controls the most expensive risk. Our installation workmanship carries its own 5-year workmanship warranty, separate from whatever the unit's manufacturer offers — meaning the flashing, sealing, and fit are backed by the people who did them, in writing.

How does an installation project run, start to finish?

It starts like all our work: send photos of the opening or the project to (973) 564-0958 or through the quote form, get an answer the same day, and book an onsite assessment within 1–2 days. The assessment is more thorough than a typical installer's measure visit — we check the condition of the framing and sills before quoting, because installing a new window over hidden rot is a disservice we decline to sell; if the opening needs repair first, you'll know, with a price beside it. Units are then ordered or built, and installation is scheduled — most single-family scopes complete within 1–2 weeks of the units arriving. On the day: old unit out clean, opening inspected and corrected, sill pan formed, unit set level and square, flashing lapped correctly, air-sealed inside, water-managed outside, trimmed, and tested. The crew is fully insured, we work Mon–Fri 8:00 AM – 6:00 PM, and we leave you with the one thing most installations never include: a wall assembly we'd bet our warranty on — because we do.
