Premier Exterior Remodeler in Sullivan’s Island, SC
American Custom Exteriors has worked on barrier island homes for over 40 years. Living out here means dealing with salt fog, baking summer sun, and tropical weather that tears through standard building materials. As a family-owned team, we focus on tough exterior work built for coastal South Carolina, keeping your home tight against the elements without losing its lowcountry style. Give us a call at 843-518-9923 to talk through what your home needs.
Building for Life on a Barrier Island
Island homes live a hard life. Salt air slowly corrodes bare metal, high humidity rots untreated wood from the inside out, and seasonal storms test every seam on your roof and siding.
Standard mainland building tactics simply do not hold up here. You need heavy-duty materials, marine-grade hardware, and installation methods tailored specifically to high-wind areas. That is where our decades on the island come in. We take the time to seal every edge, flash every window correctly, and select materials that stand up to constant exposure across Charleston County, SC near historic Charleston.
How We Help Protect and Update Your Home
From roof replacements and impact windows to custom decks and siding, we deliver tailored exterior solutions for Sullivan’s Island homes.
Tearing Off and Replacing Old Roofs
When salt spray and wind wear down a roof, patch jobs only buy you so much time. We strip old shingles down to the deck, inspect for damage, and install high-wind shingle or metal systems.

New Construction and Roof Expansions
Adding onto an existing layout or putting up a new build requires framing and professional roof installation that strictly meets coastal high-wind building codes.

Impact Windows That Cut Noise and Drafts
Swapping old single-pane windows for impact-rated glass gives you solid protection against flying storm debris while cutting down outside noise and lowering summer energy bills.

Framing and Sealing Windows for New Builds
Putting new window openings into an addition takes careful flashing work. We frame, level, and seal every opening using thick moisture barriers engineered for high-humidity environments.

Decks Built for Salt Air and Heavy Foot Traffic
An island porch or back deck needs to handle rain, sun, and wet feet. We build custom structures with expert deck installation using composite boards and stainless steel hardware.

Structural Repairs, Porches, and Exterior Carpentry
Barrier island homes often need targeted structural work like repairing rotted deck joists, replacing worn trim, or building screened lanais that keep pests out.

Custom Gutters Made Right on Site
Heavy lowcountry rainstorms drop huge volumes of water fast. We roll out seamless aluminum gutters right from our truck on site, fitting them to the exact length of your eaves.

Fiber Cement Siding That Stands Up to Humidity
Traditional wood siding struggles against damp island air. We perform complete siding replacement using fiber cement panels that resist rot, pests, and salt spray.
Learn MoreWhat 40 Years of Island Work Teaches You
Working out here for four decades teaches you that short cuts always show up after a couple of coastal winters. We run our business on honest communication, solid craftsmanship, and realistic timelines.
Four Decades on the Coast
40 years of hands-on experience means we know how local wind and moisture affect every joint, nail, and plank on a barrier island home.
Island-Tested Materials
We choose marine-grade fasteners, heavy vapor barriers, and impact-rated components built specifically for harsh coastal conditions.
Tailored Detail
No two lowcountry homes are built identical. We adjust trim details, window styles, and deck layouts to fit your specific structure.
Family-Owned Accountability
You deal directly with our local team. We show up when we say we will, keep your property tidy, and stand behind our work.
What to Expect From Start to Finish
Good exterior work starts with a realistic plan. We keep the process simple and transparent from the initial conversation to the final walk-around.
Initial Site Inspection
We come out to your house, look at your current exterior, take measurements, and point out any hidden moisture damage or wear.
Material and Layout Selection
We walk you through durable material options like composite deck shades or impact window lines, and pull the necessary permits.
Active Construction
Our crew works steadily, keeping the site swept up daily and making sure opened roof sections or walls are weather-tight before leaving every evening.
Final Inspection
We walk the property with you, check all trim joints and fasteners, and verify everything matches your expectations before wrapping up.

Common Questions Homeowners Ask Us
Answers to frequently asked questions about exterior remodeling on Sullivan’s Island, SC.
Yes, we take on projects across the entire island, from houses along Middle Street to properties near Station 12 and the lighthouse. Being local means we can head right over for site visits, evaluate your exterior, and plan work around local tide and wind conditions.
It depends on what we are doing and what the weather gives us. A basic gutter job or window swap might take two or three days. Replacing your siding or framing a large custom deck usually runs one to three weeks. If severe storms move in, we secure your home and resume as soon as conditions clear up. We give you a clear schedule before starting.
Call us at 843-518-9923 or drop us a message online. We schedule a time to come out, measure your project area, inspect the existing structure, and talk through material choices. Afterward, you get a straightforward written estimate laying out materials and labor with no high-pressure tactics or surprise add-ons.
Yes. Many island homes have distinct lowcountry details, from specific trim profiles to deep porch overhangs. We source fiber cement lap siding, historic window grid styles, and custom railings that respect your home's character while bringing structural strength up to modern standards.
Salt accumulation can dull finishes over time, so we suggest spraying down siding, window frames, and exterior doors with fresh water from a garden hose twice a year. Keep gutters clear of oak leaves, and do a quick visual check on deck boards after big windstorms.
That is the primary reason we use fiber cement, stainless steel hardware, and impact glass. Everything we install meets or exceeds high-wind building codes for coastal zones so your home remains protected during tropical weather.
Yes. The town has strict guidelines on tree protection, structural attachments, and coastal development. As an experienced Exterior Remodeler in Sullivan’s Island, SC, we handle the permit applications, submit structural drawings, and schedule the municipal inspectors so you do not have to worry about administrative delays.
National companies often send rotating crews who are not familiar with local salt fog, coastal code requirements, or island tree rules. Working with a family business means you get direct contact, experienced local crews, and accountability long after the job is finished.
