Your siding is the weather barrier that keeps water, wind, and drafts on the outside where they belong — and it sets the whole look of your home. When it is installed right, it sheds Mid-Atlantic rain, stands up to nor'easter gusts, and keeps conditioned air inside instead of leaking out through gaps and failing seams. As the siding contractor Delaware homeowners call first, Marathon Restorations installs fiber-cement, engineered-wood, and vinyl siding that stays tight and true for decades. The same crew that starts your project finishes it: clean lines, straight reveals, properly lapped flashing, and a job site we sweep every day.
We serve homeowners across Delaware, Maryland, and Pennsylvania, and we know what our weather does to a wall. Freeze-thaw cycles, wind-driven rain off the coast, summer humidity, and hard afternoon sun all punish siding that was cut short, back-butted poorly, or hung without a real drainage plane behind it. Getting the layers right — sheathing, weather-resistant barrier, flashing, then siding — is what turns a good-looking exterior into one that actually protects the house behind it.
There is no single "best" siding; there is the right material for your home, your budget, and how long you plan to stay. We walk you through the honest trade-offs so you are not guessing.
Siding is only as good as the details that frame it. We wrap the job with cellular-PVC and composite trim that will not rot around windows, doors, and corners; vented soffit that lets your attic breathe and helps prevent moisture and ice problems; and clean, straight fascia that gives the roofline a crisp edge and supports your gutters. Getting these details right is what makes a siding job look finished rather than merely covered — and it seals the openings where water most often finds its way in.
A siding replacement is also a chance to upgrade how your home performs. Adding a continuous layer of rigid foam or a fully adhered weather-resistant barrier under new siding cuts the drafts and thermal bridging that make rooms feel cold in winter and stuffy in summer — so your HVAC works less and your bills settle down. Insulated and thicker siding profiles also knock down outside noise, so the house feels calmer inside. And because the finish is factory-applied or engineered in — as it is with James Hardie ColorPlus siding — you get curb appeal that holds its color and shape for decades instead of a repaint every few years.
As a fully insured siding contractor Delaware relies on, we treat every wall like it is protecting our own family — premium materials, manufacturer-certified installation, and a written warranty covering both labor and materials. When we leave, your home is sealed, straight, and ready for whatever the weather brings.
New siding, house wrap, and flashing work together to keep water and drafts out — protecting the structure, not just the look.
