Siding Contractors in Smithtown, NY

Siding for Smithtown's Older Lots and Big Trees

The Smithtown hamlet surrounds the Bull on Jericho Turnpike and spreads south toward the Expressway and north toward the river. The housing is varied: center-hall colonials and farm ranches from the 50s and 60s on half-acre and acre lots, 70s and 80s splits off Route 111 and Landing Avenue, and a handful of older homes near Main Street and the Smithtown Landing area. Much of it has aluminum or early vinyl that has run its course. AP Siding & Windows replaces it with horizontal lap, insulated vinyl, vinyl shake, cedar shake, board and batten, or fiber cement, and takes on the windows and roof when they are due too.

Smithtown is wooded and hilly compared to the South Shore. Tall oaks keep a lot of walls in shade, and the Nissequogue River valley adds humidity. Mold on the north side and peeling trim are the usual complaints. On the ridges and open stretches near the Expressway, wind and sun do the damage instead. We approach each house by elevation: drainage wrap and ventilation behind the siding on damp sides, heavier UV-stable panels on sun-struck walls, and corrosion-resistant fasteners throughout. On the older homes near the Landing we also expect to find and fix sheathing rot that has been hidden for years.

Siding services we provide in Smithtown

Siding replacement

Full tear-off to sheathing, repair of anything we find underneath, new water-resistive barrier, and new siding with trim. This is most of our Smithtown work.

Siding repair

Storm damage, cracked or loose panels, and rot behind the siding. Worth doing when the rest of the wall has life left in it, and worth being honest about when it does not.

Insulated vinyl siding

Contoured foam backing that adds R-value across the studs. The single best fit for Smithtown's post-war stock.

Fiber cement siding

James Hardie and similar. The choice for colonials and for older houses near the village where profile and trim detail have to look right.

Cedar and cedar-profile siding

Natural cedar shake and clapboard for period homes, plus cedar-look vinyl and composite when you want the appearance without the maintenance.

Trim, soffit, fascia and gutters

Aluminum trim wrap on windows and doors, plus new soffit and fascia so the whole exterior finishes at the same time rather than in two visits a year apart.

What we would put on a Smithtown house

• Insulated vinyl is what we recommend most often here, because it suits the post-war stock this town is full of. Those capes, ranches and splits were framed 2x4 with thin wall insulation, and the contoured foam backing adds R-value across the studs where the framing normally bleeds heat straight out. It also stiffens the panel, which matters on the long flat runs of a split level where standard vinyl can read wavy.
• Fiber cement is the choice for the colonials north of 25A and for the older houses near the village, where profile and trim detail have to look right. It holds a painted finish for years, will not soften in summer heat, and carries a Class A fire rating. It is heavier and needs a flat, sound nailing surface, which is part of why we tear off rather than go over.
• Standard vinyl still does the job on a defined budget, and modern fade-resistant panels in the right profile look considerably better than what went on these houses in 1991. On Smithtown's shaded lots we will steer you away from the palest colors, because that is where the green cast shows worst.

What siding costs in Smithtown

We do not quote over the phone, because phone numbers change once somebody actually looks at the house, and that is how homeowners end up with a price that moves after the contract is signed. What we can tell you is what drives the number.

Square footage and elevation count

A cape with four simple elevations prices very differently from a split level with dormers, gable returns, and a bump-out.

Material

Standard vinyl, insulated vinyl, and fiber cement sit at three different price points, and the gap widens on larger houses.

What is behind the old siding

This is the Smithtown variable. On houses that were re-sided over the original material in the 80s or 90s, there is a real chance of sheathing repair once we tear off. We open a section during the estimate specifically so this does not become a change order later.

Trim scope

Whether you wrap the windows and doors and replace soffit and fascia at the same time. Doing it together costs less than doing it twice.

You get an itemized written price after we measure on site, and it does not change unless you change the scope.

Permits for siding work in Smithtown

Exterior work in the hamlet permits through the Town of Smithtown Building Department, which sits on Redwood Lane behind Town Hall and has moved a good range of residential applications online.

Here is the part that catches people out. Three incorporated villages sit inside the township, and the Town will not accept applications for properties inside them. The Village of the Branch, the Village of Nissequogue, and Head of the Harbor each run their own building department with their own rules. Village of the Branch addresses read as Smithtown, NY 11787, exactly like the rest of the hamlet, so homeowners there routinely file with the Town and lose a week finding out it was the wrong desk.

One more thing worth knowing if you own an older house here. Smithtown did not require building permits before 1947, so for houses built before then the Town issues what it calls a History Letter, or Letter in Lieu, rather than a certificate. If you are selling and a title search turns up missing certificates on a pre-1947 house, that is the route, and it is worth starting before the siding work rather than after.

We confirm which jurisdiction your property is actually in before anything gets filed. It takes five minutes and it saves the kind of delay that pushes a spring job into summer.

How the job runs

1. One We come out, measure, and open a section of the existing siding so you can see what is behind it. No phone estimates.
2. Two You get an itemized written price with the material, color, trim scope, and expected schedule on it.
3. Three We confirm the permit authority for your address and file what is required.
4. Four Our own installers do the work. Tear-off to sheathing, any repairs, new water-resistive barrier, then siding and trim. Deliveries get staged neatly, the driveway stays usable, and we magnet-sweep for nails before we pull out each day.
5. Five Walkthrough with you before we call it finished.

Smithtown Sections We Work In

The streets around Main Street, Maple Avenue, and the Smithtown Landing area near the river have some of the oldest homes, set on sloped, wooded lots. South of Jericho Turnpike off Route 111 and Brooksite Drive the neighborhoods are 60s and 70s colonials and splits on half-acre lots. The area near Smithtown High School West and Blydenburgh Park is similar, with larger homes near the park. Along Landing Avenue toward Kings Park the lots are bigger and some homes older. The Village of the Branch east of Route 111, and Head of the Harbor and Nissequogue to the north, are separate villages with their own rules.

Frequently asked questions

What goes into a siding quote for a Smithtown home?

We start with measured wall area, which on a Smithtown center-hall colonial is more than most people expect. Then we factor in the material, tear-off, and the trim, soffit, and window wrap. Steep or wooded lots can add access time. Vinyl is the least expensive, fiber cement the most, cedar in the middle. The written price comes after we measure in person, not before.

Do I get a siding permit from the Town of Smithtown or a village?

If your address is in the Smithtown hamlet, permits go through the Town of Smithtown Building Department. If you are inside the Village of the Branch, Head of the Harbor, or Nissequogue, your village hall is the permit authority and each has its own process. Like-for-like siding often needs no permit, but we confirm your jurisdiction and handle whatever filing is required.

Which siding does best on a shaded Smithtown lot?

Shade and the humidity off the Nissequogue mean north and east walls stay damp. Fiber cement is the most resistant choice, and insulated vinyl does well too. Cedar shake looks right on the older homes but needs regular sealing under a tree canopy. What matters most is a proper drainage plane behind the siding. That, plus keeping the bottom course off the mulch, prevents rot.

How long will siding take on my Smithtown house?

A vinyl re-side on an average Smithtown ranch or split takes three to five working days. A two-story colonial, a fiber cement job, or an older house with rot repairs takes longer. Sloped lots can slow staging slightly, and we lose a day now and then to rain. We give you a realistic schedule after the measure and let you know promptly if it shifts.

Should I replace windows and siding at the same time in Smithtown?

If your windows are original or from the first replacement wave, yes. With the siding off we can pull them, flash the openings to the sheathing, and install new double-hung, casement, bay and bow, sliders, awning, basement, or custom-shape windows in vinyl or fiberglass. Then the new siding runs tight to the frames. Doing both at once gives a sealed wall and avoids rework.

I live in Head of the Harbor. Are there extra rules for siding?

Head of the Harbor and Nissequogue are incorporated villages with their own building departments, and both have design and preservation considerations in parts of the village. Some properties sit in or near historic areas or have architectural review. We check with the village before quoting so the material and color you choose will be approved, and we handle the village permit when one is required.
