When siding fails in East Hanover, it rarely fails quietly. Water finds its way behind the panels, substrate starts to rot, and what looked like a cosmetic issue becomes a structural one. The homes most at risk are the split-levels and bi-levels built between the 1960s and 1980s and a significant portion of East Hanover’s residential stock falls right in that window. These homes have reached the point where original or once-updated siding is simply done.
New siding changes the equation. Your home stops losing heat through gaps and compromised insulation. The exterior holds up against the freeze-thaw cycles that hit this part of Morris County hard every winter. You stop worrying about what’s happening behind the wall every time it rains. And with East Hanover’s median home values now sitting around $760,000 up nearly 20% in a single year the financial case for protecting that asset is straightforward.
The right siding installation also means you’re not doing this again in ten years. Quality materials installed correctly, over a properly inspected substrate, with a moisture barrier that actually does its job that’s what separates a project that holds from one that just looks good for a season or two.
Proline Construction is a family-owned contracting company based in northern New Jersey, serving homeowners across Morris County and Essex County since 2018. East Hanover sits right at that county line and it’s territory we know well, from the permit process at 411 Ridgedale Avenue to the housing stock that lines the streets between Route 10 and the Troy Meadows wetlands.
We’re BBB Accredited and hold GAF Preferred Contractor status both verifiable, both earned. Our NJ Home Improvement Contractor Business license number is 13VH09838700, and you can confirm it in under two minutes through the NJ Division of Consumer Affairs. We carry full insurance and meet every requirement under New Jersey’s updated 2024 contractor licensing law.
What that means for you practically is simple: no liability exposure, no permit shortcuts, and no surprises after the job is done. Every project comes with a full written warranty covering both materials and workmanship because a manufacturer’s warranty alone won’t cover an installation mistake.
It starts with a free consultation. We come out, look at the full exterior, and give you an honest read on what’s going on whether that’s a few damaged panels that can be repaired or a full replacement that’s overdue. If there’s any sign of moisture infiltration or substrate damage, we document it and walk you through what we found before anything else is discussed.
From there, we handle the permit process with East Hanover’s Construction Department. Siding replacement requires both a zoning permit and a building permit under the NJ Uniform Construction Code, and it’s our job to get that paperwork right not yours. The township requires permit applications to be acted on within 20 business days, so we move efficiently to keep your project on schedule.
Once permits are approved, installation begins with substrate preparation. If we find rot or damaged sheathing under the old siding which is common in East Hanover homes from this era we address it before a single new panel goes up. We then install the moisture barrier, followed by the siding itself, with careful attention to seams, corners, trim, and all penetrations. East Hanover’s winters are hard on anything that isn’t sealed correctly, so that detail work isn’t optional. When the job is done, we walk the exterior with you before we consider it finished.

Not every East Hanover home needs the same solution. A 1970s split-level on the western side of the township where ambient moisture from Troy Meadows is a real factor has different needs than a newer colonial closer to the Route 10 corridor. The material you choose matters, and so does the installation approach behind it.
Vinyl siding remains the most common choice for good reason: it’s durable, low-maintenance, and handles the thermal cycling of New Jersey winters without cracking when installed correctly. Insulated vinyl adds a layer of energy performance that older East Hanover homes many of which were built before modern insulation standards can genuinely benefit from. Fiber cement, including James Hardie products, is the premium option for homeowners who want the look of wood without the maintenance liability. It holds paint longer, resists moisture more aggressively, and performs well in the kind of humid continental climate that defines this part of Morris County.
Beyond full replacement, we also handle siding repair for situations where the damage is isolated storm-cracked panels, sections that have pulled away from the wall, or areas where moisture has gotten in but hasn’t spread. If repair makes more sense than replacement, we’ll tell you that. And if a full replacement is what the home actually needs, we’ll show you exactly why before we recommend it.
Yes and it’s worth understanding exactly what that means before you hire anyone. East Hanover Township requires a zoning permit for any change to a property, and siding replacement also falls under the NJ Uniform Construction Code, which means a building permit is required as well. Both applications go through the Construction Department at 411 Ridgedale Avenue, and the township is required by ordinance to act on complete applications within 20 business days.
The practical risk of skipping permits isn’t just a fine. If unpermitted work is discovered during a future home sale and it often is you can be required to have the work inspected, redone, or torn out entirely. Any contractor who tells you permits aren’t necessary for siding work in East Hanover either doesn’t know the local code or is cutting corners intentionally. We handle the full permit process as a standard part of every project, so you’re covered from the start.
The honest answer is that it depends on how far the damage has spread and you often can’t tell from the outside alone. Cracked, faded, or warped panels on one section of the home might be a repair situation. But if moisture has been getting behind the siding for years, the damage is usually more widespread than it looks. In East Hanover specifically, homes built in the 1960s and 1970s are at the age where original or early-replacement siding has simply run its course, and what looks like surface wear often points to substrate issues underneath.
During a free consultation, we look at the full picture not just the visible panels, but the condition of the substrate, the state of the moisture barrier, and whether there are signs of rot or infiltration behind the wall. If repair makes sense, we’ll tell you that and quote it honestly. If replacement is the smarter call for the long term, we’ll show you why. You won’t get a replacement recommendation just because it’s a bigger job.
The freeze-thaw cycle is the biggest mechanical threat to siding in this part of Morris County. Every time temperatures cross the 32°F threshold which happens repeatedly from late fall through early spring in East Hanover siding panels, fasteners, and the substrate underneath expand and contract. Over time, that cycling loosens seams, opens gaps, and creates entry points for moisture.
Vinyl siding handles freeze-thaw well when it’s installed correctly the key word being correctly, because vinyl installed too tight or with improper fastening will buckle and crack under thermal stress. Insulated vinyl adds a layer of rigidity that helps it perform even better in cold conditions. Fiber cement is the most dimensionally stable option in extreme temperature swings and resists moisture absorption more aggressively than vinyl, which matters given East Hanover’s position between the Passaic and Whippany Rivers. Whatever material you choose, the installation quality and the moisture barrier behind it matter just as much as the product itself.
For a typical East Hanover home a split-level or colonial in the 1,800 to 2,500 square foot range full siding replacement generally runs between $12,000 and $30,000 depending on the material chosen, the size of the home, and what’s found under the existing siding. Vinyl installation runs roughly $300 to $800 per square (100 square feet), while fiber cement typically falls in the $700 to $1,500 per square range.
What can push a project toward the higher end is substrate condition. Homes from the 1960s and 1970s which make up a significant portion of East Hanover’s housing stock sometimes have damaged sheathing, failed vapor barriers, or rot that needs to be addressed before new siding goes up. A contractor who gives you a rock-bottom quote without inspecting the substrate is either not planning to address those issues or will hit you with change orders once the old siding comes off. We document substrate conditions before we quote the full scope, so you know what you’re actually agreeing to.
Start with the basics that are actually verifiable. Any contractor doing residential improvement work in New Jersey is required to hold a current NJ Home Improvement Contractor Business registration you can confirm any license number at the NJ Division of Consumer Affairs website in about two minutes. Since January 2024, updated state law also requires contractors to carry a compliance bond and workers’ compensation insurance. If a contractor can’t produce proof of both, that’s a real liability for you as the homeowner.
Beyond licensing, look for someone who handles permits as a standard part of the process not as an add-on or something they suggest skipping. Ask what happens if substrate damage is found once the old siding comes off, and get the answer in writing. A written workmanship warranty is non-negotiable on a project of this size. East Hanover’s housing stock and permit requirements are specific enough that local experience matters a contractor who works regularly in Morris County will handle the process more smoothly than one who’s treating your home as an unfamiliar market.
Yes and acting quickly after storm damage is genuinely important. When siding panels are cracked, blown off, or compromised by ice, the exterior envelope of your home is open. Moisture infiltration that starts immediately after a storm can reach the sheathing and insulation within days, and once that process starts, the repair scope grows fast. East Hanover sees its share of nor’easters and winter ice events, and the homes most vulnerable are the older split-levels and bi-levels where the original or aging siding was already under stress before the storm hit.
We offer emergency siding services specifically for situations like this. We assess the damage, secure the affected area to stop further infiltration, and walk you through the full repair scope so you understand what needs to happen and in what order. If the damage is covered by homeowner’s insurance, we can document the conditions clearly to support your claim. The goal is to stop the problem from compounding not to turn a manageable repair into a full replacement by waiting too long to address it.
