Your siding isn’t just about curb appeal—it’s your home’s first line of defense. When we install your new siding in Thornwood, you get materials that can handle wind speeds up to 110 mph, the kind of protection that keeps moisture out and energy costs down.
You won’t be repainting every few years or dealing with rotting boards. Instead, you’ll have a home that looks great and performs even better, season after season. That’s the difference between siding that’s just installed and siding that’s installed right.
The result? Lower energy bills, zero maintenance headaches, and the peace of mind that comes from knowing your biggest investment is properly protected.
We at Certified Contracting Services Inc have been protecting homes across the Northeast for years, and we understand what Westchester County weather can do to your siding. From the hurricane damage we’ve seen in places like White Plains to the nor’easter destruction in Yonkers, we know this area demands serious protection.
We’re not the cheapest option in Thornwood, and that’s intentional. You’re not just getting siding—you’re getting materials that won’t fail when the next big storm hits, installation that won’t void your warranty, and a team that shows up when we say we will.
Our crews have seen every type of siding problem this climate can create, from ice damage to summer heat warping. That experience means we know exactly how to install your siding so it performs for decades, not just years.
We start with a thorough inspection of your current siding and the structure underneath. Too many contractors skip this step, but we need to see what we’re working with—any moisture damage, structural issues, or problems that could affect your new siding’s performance.
Next, we remove the old siding completely when needed. This isn’t always necessary, but when it is, we do it right. We’ll show you exactly what’s behind your current siding and address any issues before moving forward.
Then comes the installation itself. We install proper insulation backing, ensure every piece is sealed correctly, and use installation techniques that account for Westchester’s temperature swings and weather patterns. Every panel gets secured to handle the wind loads we see here, and every seam gets attention to prevent moisture intrusion.
The final step is a complete walkthrough with you, making sure everything meets our standards and yours before we consider the job complete.

We work with three main siding types because they’re the only ones that make sense for our climate. Vinyl siding gives you the most cost-effective protection—around $8.50 per square foot installed—and handles our temperature swings without cracking or fading.
Hardie fiber cement siding costs more upfront, typically $11 per square foot, but it’s practically indestructible. Fire-resistant, insect-proof, and built to handle everything from ice storms to summer heat without warping or deteriorating. Most Thornwood homeowners who choose Hardie never need to think about their siding again.
Cedar siding runs about $16-18 per square foot and requires more maintenance, but nothing matches its natural beauty and insulation properties. We install it with extra attention to moisture barriers because wood needs proper protection in our humid summers and freeze-thaw cycles.
Every material we install comes with proper insulation backing and house wrap to maximize energy efficiency. In Westchester, where heating and cooling costs can be significant, that extra insulation typically pays for itself within a few years through lower utility bills.
Most residential siding installations in Thornwood take 3-7 days, depending on your home’s size and complexity. Weather plays a role too—we won’t install when temperatures drop below 40 degrees because some materials don’t perform properly in cold conditions.
A typical 2,600 square foot home (average for Westchester) usually takes 4-5 days with our crew. We start early, work efficiently, and clean up completely each day. If we’re removing old siding first, add 1-2 days to account for proper disposal and any repairs we discover underneath.
Complex architectural features, multiple stories, or extensive trim work can extend the timeline, but we’ll give you exact dates during our initial consultation so you can plan accordingly.
For Westchester’s climate, we typically recommend either Hardie fiber cement or high-quality vinyl siding. Hardie handles our temperature extremes better than anything else—it won’t crack in winter cold or warp in summer heat, and it’s completely resistant to the moisture that causes so many problems here.
Vinyl siding works well too, especially the thicker gauges with proper insulation backing. It’s more affordable and still handles our weather patterns effectively. The key is proper installation with adequate expansion gaps to accommodate our 60+ degree temperature swings between winter and summer.
Wood siding can work but requires more maintenance in our humid summers and freeze-thaw cycles. If you choose wood, expect to restain or repaint every 3-5 years and budget for more frequent repairs than you’d need with Hardie or vinyl.
Yes, most siding replacement projects in Thornwood require permits, especially if you’re in a historic district or if the work exceeds $100 in value. Permit costs typically run $75-300 depending on the scope of work.
We handle all permit applications and inspections as part of our service. This ensures everything meets local building codes and protects you from potential fines or problems when you sell your home. The permit process usually takes 1-2 weeks, which we factor into our project timeline.
If your home is in a designated historic area, there may be additional requirements about materials and colors. We’re familiar with Westchester’s various municipal requirements and will guide you through any special considerations for your specific location.
For a typical 2,600 square foot Westchester home, expect to pay $22,000-34,000 depending on material choice. Vinyl siding runs about $22,100 total, Hardie fiber cement typically costs $28,600-34,000, and cedar can reach $45,000 including installation.
These prices include removal of old siding when necessary, proper insulation backing, all trim work, and cleanup. Additional costs might include permits ($75-300) and any structural repairs we discover during the removal process.
We provide detailed, written estimates that break down every cost so you know exactly what you’re paying for. No surprises, no hidden fees, and we’ll match any legitimate competitor’s quote for the same materials and scope of work.
Absolutely, especially when installed with proper insulation backing. We install 3/8 inch insulation board behind your siding, which significantly reduces heat transfer through your walls. Most homeowners see 10-15% reductions in heating and cooling costs.
In Westchester, where we get both cold winters and hot, humid summers, that improved insulation works year-round. Your HVAC system won’t work as hard to maintain comfortable temperatures, and you’ll notice fewer drafts and more consistent temperatures throughout your home.
The energy savings typically pay for the insulation upgrade within 3-5 years through lower utility bills. After that, it’s money in your pocket every month. Plus, better insulation often qualifies for energy efficiency rebates from your utility company.
First, our materials are designed to handle Westchester weather—including wind speeds up to 110 mph. But if storm damage does occur, your manufacturer’s warranty typically covers material defects, and our workmanship warranty covers installation issues.
Most homeowner’s insurance policies cover storm damage to siding, and we’re experienced in working with insurance companies to document damage and ensure proper repairs. We’ll help you navigate the claims process and provide detailed assessments for your adjuster.
For minor damage like a few loose panels, we offer repair services to get your home protected quickly. For major damage, we prioritize emergency repairs to prevent further moisture intrusion while planning the full restoration. Our goal is always to get your home properly protected as quickly as possible.
