Siding Contractors in Great River, NY

Siding Suited to Great River's Wooded Riverfront Lots

Great River is small, and most of it was built on former estate land along the west bank of the Connetquot. The homes are a mix: a few surviving early 1900s houses near the Bayard Cutting Arboretum, substantial colonials and ranches from the 50s and 60s on large wooded lots, and newer custom homes near Timber Point. Lots here are bigger than in the hamlets to the west, which usually means more wall and more trim. AP Siding & Windows installs cedar shake, vinyl shake, horizontal lap, insulated vinyl, board and batten, and fiber cement, and we are comfortable with the taller walls and detailed trim these houses carry.

Two things wear on siding in Great River: the river and the trees. The Connetquot and the bay bring salt and humidity up into the hamlet, and the tall oaks and pines that make the streets so pleasant also keep north and east walls shaded and damp most of the year. That combination is hard on cedar, which is why so much of it here has gone grey and soft. On these lots we keep a drainage gap behind the siding, use breathable wrap, choose fasteners that will not rust, and recommend materials by elevation. The sunny side and the mossy side rarely want the same answer.

Siding styles we install

Horizontal Vinyl Lap Siding

The classic look for capes, ranches, and colonials. Low maintenance, dozens of colors, and never needs painting.

Cedar & Cedar-Look Shake Siding

The look of cedar shakes without staining, splitting, or rot. Great on a whole home or as gable and dormer accents.

Board & Batten Siding

Vertical siding for farmhouse, modern, and coastal exteriors, often mixed with lap siding for contrast.

Fiber Cement Siding

The premium option: heavy, fire-resistant, and very durable, with a real painted-wood look.

Signs it's time to replace your siding

• Cracked, warped, or loose panels, especially after a storm
• Faded or chalky color that no longer cleans up
• Soft spots, rot, or mildew along seams and trim
• Water stains or peeling paint on interior walls
• Drafty rooms and rising heating and cooling bills

Siding and windows in one project

Replacing windows at the same time as siding is the smartest way to do both. With the old siding off, new windows can be flashed and sealed properly on every side, and all the exterior trim comes out clean and consistent. You get one crew and one schedule for the whole exterior.

Great River Areas We Cover

The streets off River Road near the Bayard Cutting Arboretum and the Connetquot have some of the oldest and largest homes, set well back on wooded lots. Toward Timber Point Road and the county park and golf course the housing is newer, with custom builds on waterfront or near-waterfront parcels. The neighborhood around Great River Road and the LIRR station is mostly mid-century colonials and ranches on half-acre lots. Along Montauk Highway near the East Islip line the lots are smaller and the homes more modest. The whole hamlet is residential and heavily treed, with the river on one side and Heckscher State Park to the south.

Great River and the Connetquot's West Bank

All of Great River is covered, from the arboretum and Timber Point down to the park boundary and up to Montauk Highway. The hamlet is compact, so our crews work it alongside East Islip and Oakdale on the same route, with Islip and Bohemia a few minutes beyond.

Frequently asked questions

Why might siding cost more on a Great River home than elsewhere?

The homes here tend to be larger, with taller walls, more gables, and more trim than an average Long Island house, which means more material and more labor. The actual price depends on measured square footage, your material choice, tear-off, and trim detail. Vinyl sits at the lower end of the range and fiber cement at the top. We measure in person before putting a price in writing.

Do I need a permit from the Town of Islip to re-side in Great River?

Great River is an unincorporated hamlet, so the Town of Islip Building Division is the only permit authority. Straight replacement siding usually does not require a permit. Larger projects that involve sheathing replacement, structural repair, or changes to window openings might. We confirm what your project needs before starting and take care of any filing with the Town.

What siding handles the shade and river moisture in Great River?

On wooded lots near the Connetquot, moisture is the issue more than sun. Fiber cement and vinyl both resist rot and do not feed moss the way cedar does. If you want cedar for the look, it can work, but expect to seal it regularly and keep the trees trimmed back. Either way, the drainage plane behind the siding is what keeps sheathing dry.

What is the timeline for siding a house in Great River?

Because Great River homes run larger, plan on the upper end of the typical range. A vinyl re-side on an average house is three to five working days, and a big colonial here with multiple gables can take more. Fiber cement adds time. Wind off the river and bay can also cost a day. We set a realistic schedule after we measure.

Does it make sense to replace windows during a Great River siding job?

On most of the mid-century homes here, yes. The original wood windows have usually been replaced once with units that were not flashed well, and the siding has to come off to fix that. We install double-hung, casement, bay and bow, sliders, awning, basement, and custom-shape windows in vinyl or fiberglass as part of the siding project, so the wall is sealed as one system.

I am near Timber Point on the water. Does that affect the siding job?

Waterfront and near-waterfront lots around Timber Point and the river mouth are often in a FEMA flood zone. Siding on its own does not usually trigger flood-code review, but if the project is large or involves a lot of sheathing replacement, the Town may apply the flood damage prevention rules. We check your lot when we quote and use wet-tolerant materials at the lowest courses.

Why Great River Homeowners Choose AP

• In-house crews. Our own installers handle Great River's larger, more detailed homes. We keep that work in-house because the trim and flashing are where quality shows.
• Written price after we measure. We measure every gable and elevation ourselves and put the price in writing. On a big wooded lot, the house is often larger than it looks from the road, and we account for that.
• Based nearby in East Northport. Great River is about 25 minutes from our shop, down the Sagtikos and east on Montauk Highway. Close enough for an easy measure and a quick callback.
