Siding Contractors in Ronkonkoma, NY

Alec's Construction replaces and repairs siding in Ronkonkoma, Suffolk County — vinyl, fibre cement and cedar, with the housewrap, flashing and sheathing repair behind it — working out of the yard in East Patchogue. Siding runs through our winter on the days above freezing, and fibre cement and cedar do not mind the cold at all.

Siding in Ronkonkoma

Ronkonkoma is inland with no salt and a lot of 1970s splits and hi-ranches still wearing original aluminum or first-generation vinyl, and the failure there is age rather than weather — brittle vinyl that cracks in the cold, aluminum that has been painted twice and is chalking again, and no housewrap behind either of them because it was not the practice when the house was built. A Ronkonkoma re-side is mostly about what goes on behind the new siding.

The Wall Behind the Siding Is the Job

Siding is a rain screen. Water gets behind every kind of siding there is — wind-driven, capillary, at every joint and every opening — and what keeps the wall dry is the water-resistive barrier behind it and the way the windows and doors are flashed into that barrier. On houses sided before the 1990s there is frequently nothing back there but building paper that failed decades ago, or bare sheathing.

A re-side is the one time the wall is open. The sheathing gets inspected and repaired where it is soft, a proper housewrap goes on, the openings get flashed in the right order — sill pan, jambs, head — and the siding goes on top as the finish. Skipping that to save a day is how a new siding job rots the wall behind it.

Materials, Honestly

• Vinyl — least cost, no maintenance, installed loose to move with temperature. Brittle in the cold, so winter installs are done with care and not on the coldest days.
• Fibre cement — holds a crisp edge and a painted finish, takes a colour change later, does not chalk or corrode. Reads as wood from the street. Fine in any weather.
• Cedar — what the older houses were built with. Beautiful, and it needs the maintenance it was always going to need. Repair in kind where it is mostly sound.

Permits in Ronkonkoma

Ronkonkoma straddles the Islip and Brookhaven line, so the governing department is confirmed by address. Siding replacement in kind is usually maintenance; where sheathing is replaced or openings change, it becomes permitted work, and we file.

Frequently Asked Questions

Is there housewrap behind the siding on a 1970s Ronkonkoma split?

Almost never. Houses of that era were sided straight over the sheathing, or over a layer of building paper that has long since failed. When the old siding comes off, the sheathing gets inspected and repaired, a proper housewrap goes on, and the windows and doors get flashed into it — and that is the part of a re-side that makes the wall last. The new siding is the finish. The wrap and the flashing are the job.

What is behind the siding that matters?

The housewrap and the flashing. The siding is a rain screen — water gets behind every siding there is — and what keeps the wall dry is a continuous water-resistive barrier with the windows and doors flashed into it in the right order. On houses sided before the 1990s there is often nothing back there. A re-side is the one chance to fix that, and it is where the money should go first.

Vinyl or fibre cement?

Vinyl costs less, needs nothing, and looks like vinyl. Fibre cement costs more, holds a crisp edge and a painted finish, takes a colour change later, and reads as a wood-sided house from the street. Both are honest choices. The wrap and the flashing behind them are identical, and that is the part not to save on.

Can you match the existing siding for a repair?

Sometimes. Vinyl profiles and colours are discontinued constantly, and a patch in a colour that has faded for twenty years will show. Where a match is not possible we side the whole elevation so the seam is at a corner, which is invisible. We tell you which it is going to be before we start.
