Siding Contractors in Ronkonkoma, NY

Re-Siding Ronkonkoma, Lakeside and Beyond

Ronkonkoma has two kinds of housing sitting side by side. Near the lake there are small cottages and bungalows from the days when this was a summer place, many expanded, dormered, and wrapped in several layers of siding over the decades. Spreading toward the Expressway and the station are the ranches, capes, and splits that filled in during the 50s through 70s. AP Siding & Windows handles both. On the cottages that often means stripping back to the framing and fixing what we find. On the postwar houses it is usually a clean tear-off and a new layer of insulated vinyl, lap, shake, board and batten, or fiber cement.

The lake changes things. Homes on the streets ringing Lake Ronkonkoma deal with humidity, shade from mature oaks and pines, and moisture that lingers on north-facing walls. That is where you see green film on old vinyl and soft spots in cedar. Farther south near the LIRR yard and Veterans Highway the lots are more open, and sun and wind take over. We match the approach to the lot: breathable house wrap and ventilation behind the siding on shaded lakeside homes, heavier UV-stable panels on the open streets, and careful flashing on every dormer and addition, because those seams leak first.

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.

Ronkonkoma Neighborhoods We Serve

The streets off Rosevale Avenue and Hawkins Avenue near the lake hold the old cottage stock, now mostly year-round homes with additions. Around Lake Shore Road and Portion Road, which is technically Lake Ronkonkoma in Brookhaven, the houses are similar and we cover them too. South of the tracks near Railroad Avenue and the Station Yards redevelopment the homes are mid-century ranches and capes. The area between Ocean Avenue and Lakeland Avenue, down toward MacArthur Airport, is a mix of 60s splits and 70s colonials. West near Smithtown Boulevard and Nichols Road the lots are a bit larger with some newer builds.

All of 11779, Whichever Town You Are In

We cover the Ronkonkoma hamlet in Islip and the Lake Ronkonkoma side in Brookhaven, plus the Smithtown corner of the ZIP near Nichols Road. The lake is the center of our route here, with Holbrook, Bohemia, and Lake Grove on the same schedule, so distance to the town line never affects availability.

Frequently asked questions

Is it expensive to re-side an older cottage near Lake Ronkonkoma?

Lakeside cottages can cost more per square foot than a plain ranch because they tend to have additions, dormers, odd angles, and sometimes rot behind the old siding. The price comes down to wall area, material, tear-off, trim, and any repairs we uncover. Vinyl runs lowest and fiber cement highest. After we measure and look behind a few pieces, you get a written price.

Which building department covers my Ronkonkoma address?

The Ronkonkoma hamlet proper is in the Town of Islip, so most permits go through the Islip Building Division. If your address is in Lake Ronkonkoma on the north side of the lake, you are in the Town of Brookhaven, and the far northwest corner of 11779 falls under the Town of Smithtown. We verify your town and file whatever your project requires.

What siding works best on a shaded lakeside lot in Ronkonkoma?

Shade and humidity near the lake mean moisture sits on north walls longer. Vinyl and fiber cement both resist that, while cedar needs regular maintenance in that setting. More important than the panel is what is behind it. We install breathable house wrap and make sure there is a drainage path, so any water that gets behind the siding can get out again.

How long does siding take on a Ronkonkoma house?

A standard vinyl re-side on a ranch or cape in Ronkonkoma runs three to five working days. Lakeside cottages with additions, multiple rooflines, and possible repairs can run longer, and fiber cement adds time because of the weight and cutting. Rain or high wind can shift the schedule by a day or two. We set a realistic timeline when we quote and keep you posted.

Can you do windows at the same time as siding on my Ronkonkoma home?

Yes. Many of the older homes around the lake have mismatched windows from different decades, and re-siding is the right moment to bring them all up to date. With the siding off, we can flash new units directly into the wall and seal everything behind the new siding. We offer double-hung, casement, sliders, bay and bow, awning, basement, and custom shapes.

My Ronkonkoma cottage has been added onto several times. Is that a problem?

It is common around the lake and it is not a problem, but it does require care. Each addition has a seam where old framing meets new, and those joints are where water gets in. We open those areas, check the sheathing, flash the transitions, and tie the new siding across them so the house reads as one structure. Rotten sills get fixed too.
