Siding Contractors in Mount Sinai, NY

Siding That Fits Mount Sinai's Mix of Old and New

Mount Sinai has two kinds of houses and not much in between. North of Route 25A, around the harbor, Crystal Brook, and the old Pipe Stave Hollow Road lanes, you find 1800s farmhouses and former summer cottages that were winterized and expanded over the years. South and east of the highway the hamlet is 1960s through 2000s subdivisions, ending with the big colonials on the former Davis Peach Farm land. AP Siding & Windows installs fiber cement and cedar on the older homes that want it, insulated vinyl and vinyl shake on the subdivisions, and board and batten or horizontal lap anywhere. We also handle the windows and roofing.

The weather here depends on how close you are to the water. Homes above Cedar Beach and along the harbor rim take a steady Sound wind with salt in it and need stainless fasteners and tight flashing. The low ground near the harbor mouth and Shore Road stays humid. Move south past 25A and the exposure drops off fast, the lots get sunnier, and the concern becomes fading on west-facing walls and moisture behind siding that was hung with no wrap in the 70s. We adjust the system for each house rather than installing the same thing everywhere.

What we would put on a Mount Sinai house

• Fiber cement Is what we put on most Mount Sinai houses that take real Sound exposure. It holds a painted finish considerably longer in salt air than painted wood does and resists the chalking coastal air causes. It is heavier and needs a flat, sound nailing surface, which is part of why we tear off.
• Insulated vinyl Works well on the sheltered parts of Mount Sinai, and it suits the post-war stock. The foam backing adds R-value across the studs and keeps long runs flat. Closer to the Sound the fastener specification matters more than the panel does.
• Standard vinyl Performs better near the water than people expect, since it has no painted finish to lose to salt air. What matters more on an exposed Mount Sinai house is the fastener specification and how the seaward elevation is detailed.

Permits for siding work in Mount Sinai

Exterior work here permits through the Town of Brookhaven. Brookhaven is the largest township in New York State by land area, and permit review can run longer than the smaller towns to the west, so it is worth filing early rather than at the point you want to start.

The part worth checking first: Brookhaven contains eight incorporated villages, and the Town does not issue permits for any of them. Belle Terre, Bellport, Lake Grove, Old Field, Patchogue, Poquott, Port Jefferson and Shoreham each run their own building department. Several of them share mailing addresses and ZIPs with the surrounding hamlets, which is how homeowners end up filing at the wrong desk.

We confirm which authority covers your address before anything is filed.

How the job runs

Mount Sinai Sections We Serve

Crystal Brook Park, the private community dating to the 1890s, has older homes on wooded lots near the harbor. The Pipe Stave Hollow Road area north and south of 25A mixes historic houses with 60s ranches. Along Shore Road and near Cedar Beach the homes face the Sound and harbor directly. The subdivisions off Canal Road, Mount Sinai–Coram Road, and near the schools are splits and colonials from the 60s to 80s. The Davis Peach Farm development east of Pipe Stave Hollow is early-2000s colonials and the newest housing in the hamlet. Near the Chandler Estate and North Shore Heritage Park the lots are larger and more secluded.

Every street in Mount Sinai is in our territory, from the bluffs above the Sound down to the Coram line. Miller Place and Sound Beach to the east and Port Jefferson to the west are on the same crew route, so scheduling is the same no matter which side of the harbor you are on.

Frequently asked questions

What goes into the price of siding a Mount Sinai colonial?

The newer colonials on the former peach farm land have a lot of wall and a lot of corners, so square footage and trim drive the number more than anything. The material is the next factor, with vinyl lowest and fiber cement highest, then tear-off of the existing layer. We measure in person and put the quote in writing.

Who handles permits for siding in Mount Sinai?

Mount Sinai is an unincorporated hamlet, so the Town of Brookhaven Building Division issues permits, not a village hall. A like-for-like siding swap often does not need one. Replacing rotted sheathing, altering window openings, or structural work can. Properties close to the harbor or in a mapped flood area may need an extra look. We check and handle the paperwork.

What siding lasts on a house near Cedar Beach or the harbor?

The homes along Shore Road and above the beach get salt wind off the Sound and a damp harbor breeze. Fiber cement with a factory finish is the longest-lasting option there. Insulated vinyl is a good lower-cost alternative that will not corrode. Whichever you pick, we use stainless or hot-dipped fasteners and double-check flashing at windows and corners on the water-facing sides.

How long does a Mount Sinai siding job usually run?

A vinyl re-side on a split or ranch in the 60s and 70s sections takes three to five working days. A large colonial off Pipe Stave Hollow runs longer, and fiber cement is slower on any house. Wind near the Sound costs us days that inland streets do not lose. Older harbor-area homes with hidden repairs stretch the schedule. We set the dates after measuring.

Does it make sense to do windows and siding at once in Mount Sinai?

Usually yes. The 1960s and 70s subdivisions here have windows that have aged out, and doing them with the walls open means proper flashing and new siding that meets the frame cleanly. We install double-hung, casement, bay and bow, slider, awning, basement, and custom units in vinyl or fiberglass. One crew, one schedule, and a wall that is sealed as a system.

My Mount Sinai house is a converted summer cottage. What should I expect?

The old cottages near the harbor and Crystal Brook were built light and added onto over decades. When the siding comes off we often find mixed framing, missing sheathing, and additions that were never tied in. We stop, show you what we found, and price any repair before continuing. A proper wrap and flashed openings make the biggest difference on these houses.
