Why homeowners replace their siding

Siding is your home’s raincoat. When it fails, water gets behind it and into the wall, often long before you see the damage inside. Common signs it’s time:

Warped, cracked or loose panels, especially after wind storms
Faded or chalky color on the sunny sides of the house
Soft spots, rot or mold on the sheathing behind the siding
Peeling paint inside on exterior walls, a sign of moisture getting in
Rising energy bills or drafty rooms along exterior walls
Old aluminum siding that’s dented, chalking and hard to repair

Siding and gutters belong together

This is why a gutter company does siding: most siding damage starts with water from the roof. Overflowing gutters, downspouts that splash against the wall, and missing drip edge are what stain, rot and warp siding over time.

When we replace siding, we plan the water path at the same time:

Gutters come down and the fascia and trim behind them get inspected.
New siding goes on over a proper weather-resistant barrier, with flashing at windows, doors and roof lines.
New seamless gutters and downspouts go up, sized for the roof and placed so water never runs down the new siding.

The result is an exterior that looks new and stays dry, with one crew and one schedule.

Siding questions

Should I replace my gutters when I replace my siding?

Often, yes. Gutters and downspouts usually come off during a siding job anyway, and putting old gutters back on brand-new siding wastes the opportunity. Doing both together means one crew, one schedule, and flashing and trim details that are planned to work together.

Vinyl or fiber cement, which is better?

Vinyl is lower cost, never needs painting and comes in many colors and profiles. Fiber cement is heavier, more rigid and more resistant to impact and fire, but costs more and needs repainting over time. We will walk you through both on your estimate.

Can you replace siding on just one side of the house?

Yes. Storm-damaged walls, additions and single elevations are common jobs. Matching faded existing siding can be tricky, so we will be honest about how close a match is possible.

What happens to the old siding?

Most projects remove the old siding so we can inspect the sheathing and wrap underneath. Removal and disposal are included in your written quote.

How long does a siding project take?

It depends on the size of the house and the material. Many single-family vinyl projects take a few days. We give you a timeline with your written quote.

Do you offer financing for siding?

Yes. Monthly payment options are available for siding, gutters and guards.
