Drafty windows and worn doors cost you comfort and money every month. We install energy-efficient replacement windows and exterior doors that tighten up your home, cut noise, and sharpen its curb appeal.
Because we are an exterior contractor first, every unit we install is properly flashed, insulated, and sealed into the wall system, which is where most window jobs go wrong.
We replace windows and doors as standalone projects or alongside new siding, where doing both at once saves money and gives the cleanest result. Get numbers for your home with a free estimate. Planning the backyard too? The same team handles Long Island deck builders from footings to finish.
Water finds openings. Every window and door in your house is a hole cut in the wall, and the flashing around it decides whether that hole stays dry for decades or rots the framing quietly. We treat each unit as part of the whole exterior, tying its flashing into the housewrap and sealing the frame with the same care we give a chimney.
Our crews came up on Long Island roofing jobs before we ever set a window, so we already know what salt air and wind-driven rain do to a house here. We measure your openings, tell you plainly whether inserts or full-frame units make sense, and put every number in a free written estimate before any work starts.
Windows and doors are where houses leak heat, noise, and water. Here is what replacement actually buys you, and where installs go wrong.
Modern units with proper flashing and insulation around the frame eliminate the drafts and cold spots old windows and doors leak into a home. The difference is felt the first cold night.
Energy-rated windows and insulated doors cut heating and cooling loss through the largest openings in your walls. On Long Island's heating and cooling bills, that shows up every month.
Double-pane glass and tight modern seals noticeably quiet road and neighborhood noise, and current locking hardware is a real security upgrade over decades-old units.
The install matters more than the window:
A premium window installed without flashing and insulation performs worse than a modest one installed right.
Foam-only sealing:
A bead of foam is not a flashing system. Water management around the opening is what keeps walls dry.
Measure-and-run sales crews:
If the person quoting will never touch the install, ask who will, and what their flashing detail is.
Quality vinyl and fiberglass windows last 20 to 40 years and a well-hung exterior door even longer, and small upkeep habits protect that span. Quality units installed right ask for minutes a year:
Often, yes. A fogged or cracked pane in an otherwise sound window does not force a whole new unit, and we price the smaller fix whenever it makes sense.
Fogging between double panes means the sealed unit lost its gas and its insulating value. When the frame is square and rot-free, we set a new double-pane glass unit for well under the cost of a full window. A cracked single pane is simpler still.
When the moving sash is worn but the frame is solid, a sash replacement renews glass, seals, and hardware together at a fraction of full-window cost.
When glass-only is wasted money: rotted frames, racked openings, or failed seals across half the house mean the money belongs in replacement windows. We look first, then price both options honestly in a free estimate.
Few homeowners replace every opening at once. The order matters more than the count.
1. The Weather Sides First:
South- and water-facing openings take the coastal beating and return the most comfort per dollar.
2. Failed Seals Next:
Fogged double-panes have already lost their insulating gas. They are single-pane windows wearing a costume.
3. Doors With the Project:
Entry and patio doors share the same flashing logic and cost less bundled with window work.
Three frame materials cover nearly every replacement window on Long Island, and each earns its place at a different priority.
1. Vinyl Windows:
The value standard. Welded vinyl frames never need paint, insulate well, and deliver the lowest cost per opening. Frame gauge and reinforcement decide the quality.
2. Fiberglass Windows:
The durability pick. Fiberglass expands at nearly the same rate as glass, so seals last longer and frames stay rigid through coastal temperature swings. Paintable, stronger, and a step up in price.
3. Wood-Clad Windows:
The architectural pick. Real wood interiors with aluminum or fiberglass exteriors for historic and high-end homes, at the top of the price range.
Entry doors come down to three materials, and the right one balances exposure, security, and looks.
1. Fiberglass Doors:
The Long Island workhorse. Wood-grain texture without warping or rust, real insulation value, and the best all-around performance in salt air.
2. Steel Doors:
The security and budget pick. Strongest against forced entry at the lowest cost, though coastal exposure demands a quality factory finish to keep rust away.
3. Wood Doors:
The statement pick. Unmatched depth and character for covered entries, in exchange for periodic refinishing.
Opening projects price on three inputs, and unit count is only the first.
1. Unit Quality Tier:
Builder-grade, mid-range, and premium units differ more in seals, glass, and hardware than the price gap suggests.
2. Count and Sizes:
Standard sizes install efficiently. Bays, sliders, and custom openings carry their own labor.
3. Installation Scope:
Insert replacements and full-frame installations with new flashing are different jobs, and the right one depends on the wall's condition.
Every project gets a written, itemized estimate before any work begins, so the number you approve is the number you pay.
It depends on what actually failed. The cost to install a sliding glass door rides on unit size, frame material, and the condition of the opening underneath, and glass-only work costs far less than a full unit.
A fogged or cracked panel in a slider that still rolls straight can take a new sealed glass unit alone. If the rollers, track, and frame are worn too, that money is better put toward a new door.
The same rough opening usually accepts exterior double French doors, a swap plenty of Long Island homeowners make for the look and the wider walk-through. It adds carpentry, so it prices above a straight slider-for-slider replacement.
Under every door: a sill pan flashing goes beneath each patio door we set, because a missing pan is how sliders leak into the floor framing. Your written estimate breaks out each option so you can choose.

Yes. Basement openings sit at or below grade, where flashing and drainage decide everything, and that is the exterior work our crews do all day on Long Island.
Old steel and aluminum basement units rust, fog, and leak air along the sill. We replace them, hopper styles included, with insulated units sealed tight to the foundation, and we make sure window wells drain instead of holding water against the new frame.
A finished basement bedroom needs an egress window a person can climb out of, and code sets exact minimums. We check whether your openings qualify, and where a window swap brings one up to code, we price it. If the opening itself falls short, we say so plainly during a free inspection, before you spend anything.
Window flashing ties into the wall's water barrier, which is exposed exactly once: when the siding is off.
Our Advice: If siding is in your five-year plan, do windows with it. The combined job seals better than either alone and saves real money on labor and staging.
We are not a one-brand dealership. We supply the major manufacturers and match the line to your budget and your home's exposure.
These lines cover most mid-range and premium requests on Long Island, from Andersen window replacement in wood-clad series to Pella replacement windows and Marvin fiberglass frames that handle coastal temperature swings.
JELD-WEN and Milgard bring solid vinyl value when budget leads the decision, and Therma-Tru fiberglass entry doors are our usual answer for exposed entries.
Which brand is best: the install decides more than the sticker. The best replacement windows are the ones matched to your opening and exposure, then flashed, insulated, and sealed correctly. Your written estimate prices the lines side by side.
The Foam-Only Risk:
A bead of foam is not a flashing system. Water management around the opening is what keeps the wall dry for decades.
The Builder-Grade Risk:
The gap between builder-grade and quality units is bigger than the price gap. Cheap units fail seals early and get replaced twice.
Our Approach: Every unit flashed, insulated, and sealed into the wall system as an exterior contractor does it, because the install decides more than the window does.
Before we quote anything, we look hard at what is already there. We probe sills for soft wood, see how the old flashing was run, and check the sheathing behind the trim where rot likes to hide. A window measured wrong or set over bad framing fails early, so the inspection is where the job is really won.
On installation day the same standard holds. Sill pans go under every door, low-expansion foam fills the gap around each frame, and the exterior joint gets back-caulked before the trim goes on. We have run crews this way for over 10 years, and it is why our units stay tight through noreasters instead of whistling by February.
We treat every roof like it's protecting our own family.

Being local matters in this trade because word travels. We are licensed, insured, and easy to find, and founder Benjamin Shepherd has kept the company's name on Long Island work for over 10 years. If a job of ours went sideways, you would hear about it at the deli counter long before you ever met us.
Benny's replaced our whole roof after a storm and made the insurance claim painless. Crew was on time, cleaned up every nail, and the new roof looks incredible. Could not recommend them more.
Got three estimates and Benny's was the only one who actually inspected the attic and flashing. Honest, no pressure, and the price was fair. The new roof was done in two days.
A shingle blew off and I expected the runaround. Instead Benny's came out the next morning, fixed it, and didn't even charge me. That's how you earn a customer for life.
New roof in a single day. The crew showed up on time, protected the landscaping, and the final price matched the quote to the dollar. No surprises anywhere.
Financing made a full replacement doable for us. The office kept us in the loop the whole way and the work passed inspection with zero issues. Truly professional.
Quick response after a windstorm. They tarped the roof the same day and had it fully repaired that week. Lifesavers. I recommend Benny's to every neighbor.

Yes. We install energy-efficient replacement windows and exterior doors across Long Island, and every unit is properly flashed, insulated, and sealed into the wall system, which is where most installations go wrong. Every project starts with a free estimate and a written, itemized price.
It depends on the unit tier, the size and count of openings, and whether you need insert or full-frame installation, so per-window prices vary widely. Vinyl costs the least per opening, wood-clad the most, and hidden rot adds carpentry. We give you a written, itemized estimate before any work begins, so the number you approve is the number you pay.
Sometimes, and when it is the cheaper right answer we will say so. A cracked pane or a fogged double pane in an otherwise sound frame can take new glass or a new sash, but if the frame is rotted or the seals are gone, glass-only work is money down the drain. We price both options in a free estimate so you can decide.
Ask who actually installs your windows and what their flashing detail is, because measure-and-run sales crews are where jobs go wrong. We are an exterior contractor first, so every unit is flashed, insulated, and sealed by our own crew, and you get a written estimate with no sales pressure.
Yes. We replace front entry doors, sliding glass doors, and French patio doors across Long Island, and every exterior door we set gets a sill pan under it because a missing pan is the number one source of door leaks. Door work also costs less when it is bundled with a window project.
Yes, we handle basement and egress window replacement, including code-compliant egress sizing for finished basements. Openings, flashing, and drainage are exterior work, which is exactly what we do all day. We will confirm what your basement actually needs during a free inspection.
We install replacement windows and doors from the major manufacturers, including lines like Andersen, Pella, Marvin, JELD-WEN, and Milgard, and we match the line to your budget and your home's exposure. The honest truth is the install decides more than the sticker on the glass. Your written estimate prices the options side by side.
If siding is in your five-year plan, do the windows with it. Window flashing ties into the wall's water barrier, which is exposed exactly once, when the siding is off, so the combined job seals better and costs less than doing them separately.
Remove this question. Zero measured demand for signs/when-to-replace phrasings in either TSV (greps for how long, worth, last, signs, when to, need new return nothing), and its content already lives in the deep-dive pros/cons intro. Its slot goes to the cost question at order 2.
Start with the window that bothers you most. When we come out, we walk the house together and look at every unit you are thinking about, not just that one. We measure the openings, check the frames for rot, and answer questions in plain language while you point out the drafts and sticking sashes.
Afterward you get a written estimate, itemized and free, and the decision stays yours. We hand it over, answer anything you ask, and head to the truck. Some folks book the work that same week, others wait a season, and both get the same straight answer from us when they call back.
